+`ai.use`-gated Claude assistant at `/odin` (granted to admin). **Phase 2a:
+read-only agentic assistant** — chat turns run an agentic loop
+(`agenticChat` in `src/services/ai.service.ts`, max 6 round-trips, budget
+re-checked between iterations) over the read-only tools in
+`src/services/ai-tools.ts` (invoices, offers, orders, projects, customers,
+warehouse, attendance).
+
+**Security model (do not weaken):** Odin is the **user's delegate** — the
+tool list is pre-filtered by the caller's permissions AND every handler
+re-checks them (`ctxCan`); there are **NO write tools** (writes come in
+Phase 2b as propose→confirm action cards, never autonomous). Tool handlers
+call the same service functions the routes use. Assistant turns persist
+their tool trace in `ai_chat_messages.content_json` (plain `content` stays
+the display text); the UI shows consulted-tool chips. The system prompt
+enforces plain-text replies (the chat renders pre-wrap text, no Markdown).

-> Severity tags: `[CRITICAL]` (exploitable / data-loss / breaks prod) · `[HIGH]` (real bug or security weakness) · `[MEDIUM]` (correctness/maintainability risk) · `[LOW]` (polish / nit). The `## Summary` section is written last, at the top, once every file is reviewed.
-
----
+Full file-by-file audit, 2026-06-09/10. Method: 45 independent review agents (every file read in full), plus a project-level architecture review and a dependency review; every CRITICAL/HIGH per-file finding was then re-examined by an independent adversarial verifier before being accepted into this report.
 
 ## Summary
 
-**Files reviewed:** 277 / 277 (100%) — every tracked source/config file plus `CLAUDE.md`. 8 files came back fully clean.
+**Coverage:** 304/304 in-scope files reviewed (see `REVIEW.md`); 130 files clean, 174 with findings.
 
-**Findings by severity:** **2 CRITICAL · 44 HIGH · 115 MEDIUM · 201 LOW** (≈362 total, including 9 project-level findings).
+**Per-file findings:** 0 CRITICAL, **19 HIGH**, 161 MEDIUM, 247 LOW. All 19 HIGH findings were independently verified as real (5 further candidates were downgraded during verification; none of the verified findings were refuted).
 
-**Project structure.** Contrary to the "mess from many AIs" worry, the architecture is _coherent and conventional_: a single-package Fastify-5 + Prisma/MySQL backend (clean routes → services → Prisma layering, followed consistently) serving a React-18 + MUI-v7 + TanStack-Query SPA from the same process. The layering, response-envelope, permission, audit, and React-Query conventions are applied uniformly across all ~277 files — that consistency is the codebase's real strength. The "mess" is not architectural; it is **(a) accumulated cleanup debt** — a handful of 1,300–2,400-line God-files (`warehouse.ts`, `InvoiceDetail.tsx`, `OfferDetail.tsx`, `attendance.service.ts`, `useAttendanceAdmin.ts`), ~77 `any` escape hatches, several dead modules (`STATUS_DOT_CLASS`, `ShortcutsHelp`, `useModalLock`, dead deps) and working-tree cruft — and **(b) missing guard-rails**: no ESLint, an unpinned Prettier, and tests excluded from type-checking, which is precisely why a _systemic_ Rules-of-Hooks bug and a wall of NaN-coercion gaps slipped in unnoticed. **Recommendation: keep the current core** (do not rewrite to Next.js or split repos) and spend the effort on linting + the targeted fixes below.
+**Project-level findings:** 1 CRITICAL, 2 HIGH, 13 MEDIUM, 17 LOW (details in PROJECT-LEVEL below).
 
-**Dependencies.** Healthy but drifting. `npm audit` reports **8 known vulns (6 moderate, 2 low)** — `quill` XSS (mitigated by the DOMPurify-everywhere sanitization, verified), `file-type` DoS, `react-router` open-redirect, plus transitive `ws`/`qs`/`brace-expansion`; most are non-breaking `npm audit fix`. Three **dead dependencies** (`react-datepicker`, `hi-base32`, `@types/mysql`) should be removed. Several **majors are behind** (React 18→19, MUI 7→9, Prisma 6→7, react-router 6→7, TS 5.9→6) — none urgent for an internal tool, but Prisma 6→7 and React 18→19 are worth planning. No secrets are committed (good); `.env.example` is stale and there is no committed README.
+**Project structure** — Structurally healthy: clean Fastify request pipeline, strict TypeScript across all tsconfig projects, solid ESLint/Prettier setup, exemplary `.env.example` and secret hygiene, and a real-DB Supertest suite. The main weaknesses are an incompletely applied service layer (trips/customers/received-invoices/leave-requests/quotations/warehouse keep Prisma + business logic in route files; `warehouse.ts` is 2,565 lines), ~3,700 lines of copy-pasted PDF template code across four `*-pdf.ts` route files, a fragile tsconfig-carved frontend/backend split inside one `src/` tree, naming drift (camelCase vs kebab-case, quotations-vs-offers), zero component tests for a 114-file React frontend, and documentation drift in README.md/CLAUDE.md. Consolidation work, not rescue work.
 
-**Top 5 to fix first:**
+**Dependencies** — Healthy and modern (Fastify 5, Prisma 7, React 19, Vite 8, Zod 4). The 2 critical npm-audit vulnerabilities come entirely from `concurrently`, an **unused** devDependency — deleting it clears them. The 3 moderates are one Prisma-CLI-tooling chain best fixed with an npm `overrides` pin of `@hono/node-server@^1.19.13` (do NOT take npm's suggested Prisma 6 downgrade). The quill XSS advisory is already mitigated by the existing DOMPurify/cleanQuillHtml discipline. Two deprecated `@types` stubs (`@types/dompurify`, `@types/bcryptjs`) should be removed; ~19 packages need only safe minor/patch bumps. Strategic majors to plan deliberately: MUI 7→9, react-router 6→7, puppeteer 25 (ESM-only — blocked on a CJS→ESM server move), TS 6.0 (wait for toolchain).
 
-1. **Systemic Rules-of-Hooks violation (2 CRITICAL + ~11 HIGH).** ~13 detail/form pages declare `useApiMutation` _after_ an early `return <Forbidden/>` (`OrderDetail`, `ProjectDetail` = CRITICAL; `Settings`, `Trips`, `TripsAdmin`, `Users`, `Vehicles`, `AttendanceBalances`, `AuditLog`, `LeaveApproval`, and 5 warehouse detail/form pages). React crashes ("rendered fewer hooks") when a user hits the page without the permission or permission state flips. Mechanical fix (move every hook above the guard); `eslint-plugin-react-hooks` would have caught all of them.
-2. **`roles.ts` privilege escalation (HIGH).** A non-admin `settings.roles` holder can create a role — even one named `admin` — with arbitrary `permission_ids`, and rewrite the existing admin role's permissions via PUT (no admin gate on POST/PUT, only DELETE). Real escalation/lockout path. (Pair with `trips.ts /users` and `vehicles.ts GET /` missing-permission disclosure.)
-3. **Warehouse stock + money correctness (HIGH).** `confirmIssue`/`confirmInventorySession` lock only the issue row (not item/batch), `cancelReservation` has no lock/transaction at all, and FIFO selection is a wide TOCTOU → lost updates, negative stock, double-issue. Compounded by the **schema NaN-coercion gap**: warehouse/trips/received-invoices/settings quantities, FKs, and security numbers (`max_login_attempts`, `lockout_minutes`) accept `NaN`/negatives — root cause is the missing shared coercion helper in `schemas/common.ts`.
-4. **VAT + concurrency data-integrity bugs (HIGH).** `received-invoices` JSON-create computes VAT as net-from-gross, inconsistent with the other two paths (same invoice → different stored VAT); `attendance.service.lockUserRow` uses `$executeRaw` for a `SELECT … FOR UPDATE` (the punch lock may not hold); `exchange-rates` `fetch` has no timeout (a hung ČNB endpoint blocks the event loop); `numbering`/`users`/`offers` have first-of-year / uniqueness TOCTOU races (500 instead of 409/retry).
-5. **Missing engineering guard-rails + the `nas-offers-manager` silent catches (HIGH).** Add ESLint + `typescript-eslint` + `eslint-plugin-react-hooks`, a committed Prettier as a real devDep, and type-check the tests (`tsconfig.test.json`) — this single investment would have caught #1 and a large share of the MEDIUM findings automatically. Separately, `nas-offers-manager.ts` has five fully-silent `catch {}` blocks (a failed offer-PDF save/delete is invisible), violating the project's own never-swallow rule.
+### Top 5 issues to address first
 
-**Note on test confidence:** the suite is server-side only (no component tests) and has real gaps on the _happy paths_ — no successful-login / refresh-rotation test, no happy-path `verifyAccessToken` test, and the `exchange-rates` module cache is never reset between tests (order-dependent). Warehouse FIFO is asserted only by total-quantity conservation, not oldest-batch-first. Green tests therefore give less assurance on auth and stock valuation than the count (195) suggests.
-
----
+1. **Attendance creation/editing is broken since commit 519edce (2026-06-09)** — `src/admin/pages/AttendanceCreate.tsx` (80-99): every submit 400s because always-sent empty time strings fail the new `timeString` validation, breaks/overnight fields are silently stripped, and validated "HH:MM" values crash the service (`new Date('08:00')` → Invalid Date → 500). Same schema/client/service contradiction breaks the AttendanceAdmin create/edit modals (407-442). A core daily workflow is non-functional.
+2. **Backup-code 2FA login is broken — lockout risk** — `src/admin/context/AuthContext.tsx` (263-272): backup codes are posted to `/login/totp` as `totp_code`, which the 6-digit schema always rejects; the real `POST /totp/backup-verify` endpoint is never called from the frontend. Any user who loses their authenticator is locked out. Related: the 2FA enrollment QR (`DashProfile.tsx:556`, api.qrserver.com) is blocked by the production CSP, and `Dashboard.tsx` (89-91) shows the company-wide 2FA _policy_ flag as the user's personal enrollment status.
+3. **Silent invoice data corruption on re-save** — `src/admin/pages/InvoiceDetail.tsx` (728): edit-mode hydration overwrites per-line VAT rates with the invoice-level rate (and `|| 21` turns legitimate 0% into 21%) — re-saving a mixed-rate invoice corrupts stored VAT data; `billing_text` edits are silently dropped because `UpdateInvoiceSchema` lacks the field. Same falsy-zero hydration bug in `IssuedOrderDetail.tsx` (606-611).
+4. **Trips lists/totals silently truncated at 25 rows** — `src/admin/lib/queries/trips.ts` (52-63, 95-103): the paginated response's meta is discarded, so Trips/TripsAdmin/TripsHistory compute km and business-trip totals from at most 25/100 rows with no pagination UI — wrong business numbers once data grows. Same class of bug: `orders.service.ts` ships the full PDF `attachment_data` blob inside every list/detail/totals JSON response (severe payload bloat).
+5. **`concurrently` devDependency (unused) carries both CRITICAL npm-audit vulnerabilities** (shell-quote command injection, CVSS 8.1) — remove the package, zero migration risk; then pin `@hono/node-server@^1.19.13` via `overrides` to clear the moderates.
 
 ## PROJECT-LEVEL
 
-### System core (what this app actually is)
+### Architecture & structure
 
-A **single-package full-stack monolith**, and — contrary to the "mess from many AIs" worry — the bones are coherent and conventional:
+Overall, boha-app-ts is a structurally healthy, above-hobbyist-grade codebase that mostly lives up to its own documented conventions: a clean Fastify request pipeline (CORS → cookies → rate-limit → security headers → permission guard → Zod → service → response helpers), strict TypeScript across all three tsconfig projects, a solid flat ESLint config with rules-of-hooks as an error, Prettier + format-on-save hooks, an exemplary .env.example, genuinely good secret hygiene (no env file ever committed, placeholder-only template, hard-throw on missing required vars), and a 25-file Supertest suite against a real isolated test DB. The main architectural weaknesses are (1) an incompletely-applied service layer — roughly half the entities (trips, customers, leave-requests, received-invoices, quotations, most warehouse CRUD) keep Prisma queries and business logic directly in route files, with warehouse.ts at 2,565 lines/46 endpoints and four ~800–1,100-line PDF route files containing copy-pasted inline HTML templates and helpers; (2) a single src/ tree shared by server and SPA that is carved up by fragile tsconfig include/exclude lists, leaving stragglers like src/context/ThemeContext.tsx, App.tsx and main.tsx outside the frontend's logical home; and (3) naming drift (camelCase vs kebab-case, .service suffix vs none, quotations-vs-offers domain split) plus documentation rot in README.md and a few spots in CLAUDE.md. Nothing found is critical; the recommendations below are consolidation work, not rescue work.
 
-- **Backend:** Fastify 5 JSON API. Entry `src/server.ts` registers ~29 route plugins under `/api/admin/*`. Clean 3-layer split: **routes** (HTTP, Zod validation, auth guards, `success/error` helpers) → **services** (plain exported async functions, own Prisma) → **Prisma/MySQL** (52 models, snake_case). Cross-cutting infra: JWT(HS256)+TOTP auth with hashed refresh-token rotation, custom security headers + prod CSP, `node-cron` (invoice alerts), Puppeteer (PDF), nodemailer (email), Anthropic SDK (Odin AI).
-- **Frontend:** React 18 SPA in `src/admin/`, built by Vite, **served by the same Fastify process** (Vite middleware in dev, `@fastify/static` in prod). MUI v7 + Emotion, TanStack Query for all data, React Router 6. Component kit in `ui/`, pages lazy-loaded.
-- **Build topology:** one `package.json`, three tsconfigs via a solution file — `tsconfig.server.json` (CJS → `dist/`) and `tsconfig.app.json` (ESM, `noEmit`, Vite owns emit). Tests (Vitest) hit a real MySQL test DB.
+- [HIGH] **Separation of concerns — service layer** — The documented 'services own Prisma, routes stay thin' pattern is applied to only ~half the entities: trips.ts (20 prisma calls), customers.ts (12), received-invoices.ts (15), leave-requests.ts, quotations.ts and warehouse.ts (79 prisma calls, 46 endpoints, 2,565 lines) all run Prisma queries and business decisions directly in route handlers, while attendance/plan/orders/invoices have proper \*.service.ts files.
+  - Recommendation: Incrementally extract services for the route-resident entities (start with warehouse CRUD and received-invoices since they carry the most logic), and split src/routes/admin/warehouse.ts into a folder of sub-route files (items, receipts, issues, reservations, inventory) registered under the same prefix. Do it opportunistically per the existing 'convert when you touch them' rule, but track it so it converges.
+- [HIGH] **Code duplication — PDF routes** — invoices-pdf.ts (1,097), orders-pdf.ts (917), issued-orders-pdf.ts (880) and offers-pdf.ts (784 lines) each embed a full inline HTML template plus four copy-pasted helper sets (formatNum, formatDate, cleanQuillHtml, a per-file JSDOM+DOMPurify instance) — ~3,700 lines of near-parallel presentation code living in the routes layer, where a sanitization or layout fix must be applied four times.
+  - Recommendation: Extract a shared src/pdf/ (or src/services/pdf/) module: one sanitize+cleanQuillHtml pipeline, one number/date formatter set, one base document template with per-document sections. The PDF routes then shrink to data-fetch + template-call, matching the thin-route convention.
+- [MEDIUM] **Project layout — frontend/backend split** — Server and SPA share one src/ tree carved up by tsconfig include/exclude lists: tsconfig.server.json includes src/\*_/_ then excludes src/admin, src/context, App.tsx, main.tsx, **tests** — so any new frontend folder created outside src/admin silently lands in the server build. Symptoms already exist: src/context/ThemeContext.tsx lives outside src/admin/context (where AuthContext/AlertContext live), and the SPA entry files App.tsx/main.tsx sit at src/ root next to server.ts.
+  - Recommendation: Move ThemeContext.tsx into src/admin/context (it is only excluded from the server build, nothing server-side imports it), relocate App.tsx/main.tsx under src/admin (adjust index.html entry), and flip tsconfig.server.json from an exclude-list to an explicit include of server directories (config, routes, services, schemas, middleware, utils, types, server.ts). That makes the boundary structural instead of memorized.
+- [MEDIUM] **Consistency — file naming** — Mixed naming conventions in the same directories: planCategory.service.ts / planCategory.schema.ts (camelCase) vs every sibling in kebab-case; services split between suffixed (warehouse.service.ts) and unsuffixed (auth.ts, audit.ts, mailer.ts, exchange-rates.ts, nas-\*.ts, system-settings.ts); src/admin/lib/queries has auditLog.ts beside issued-orders.ts; src/utils has planAuditDescription.ts beside czech-holidays.ts; and the offers domain is named 'quotations' only in routes/admin/quotations.ts (registered at /api/admin/offers, with offers.service.ts, offers.schema.ts, Offers.tsx everywhere else).
+  - Recommendation: Standardize on kebab-case files with .service.ts/.schema.ts suffixes for entity modules (rename planCategory._ → plan-category._, auditLog.ts → audit-log.ts, planAuditDescription.ts → plan-audit-description.ts, quotations.ts → offers.ts), and either suffix the bare services or document that unsuffixed files are infrastructure helpers, not entity services. Pure renames — git tracks them, low risk, one PR.
+- [MEDIUM] **Tooling — package.json contradicts migration policy** — package.json ships db:push (prisma db push) and db:pull scripts even though CLAUDE.md's golden rule is 'NEVER use prisma db push' — a one-keystroke footgun that bypasses migration history, and there are no db:migrate/db:deploy scripts for the blessed path.
+  - Recommendation: Remove db:push (and db:pull, or rename it db:pull:DANGEROUS), and add scripts for the sanctioned workflow instead: db:migrate → prisma migrate dev, db:deploy → prisma migrate deploy, keeping db:generate/db:studio.
+- [MEDIUM] **Testing — zero component tests for a 114-file React frontend** — All 25 test files in src/**tests** are server-side API tests (good breadth there); the only frontend test is a theme-token unit test (src/admin/theme.test.ts). Pages of 800–2,300 lines (InvoiceDetail.tsx 2,278; OfferDetail.tsx 2,012; CompanySettings.tsx 1,542) carry untested form/validation/permission logic, and the single node-environment vitest.config.ts cannot host jsdom component tests.
+  - Recommendation: Adopt Vitest projects (workspace) config: the existing node+real-DB project unchanged, plus a jsdom project with @testing-library/react for src/admin/\*_/_.test.tsx. Start with the shared kit (DataTable, Select, ConfirmDialog) and the most logic-heavy pages; even a handful of tests around the detail-page save flows would cover the riskiest untested surface.
+- [MEDIUM] **Frontend structure — monolithic page components** — Detail/settings pages routinely exceed 1,000 lines (InvoiceDetail 2,278; OfferDetail 2,012; CompanySettings 1,542; IssuedOrderDetail 1,465; Settings 1,356; ReceivedInvoices 1,316) because each page owns its forms, modals, line-item editors and mutations inline, while src/admin/components only holds a small set of shared pieces.
+  - Recommendation: When touching these pages, split per-page subcomponents into feature folders (e.g. src/admin/pages/invoices/{InvoiceDetail.tsx, InvoiceItemsEditor.tsx, InvoicePaymentsPanel.tsx}) keeping data logic in the parent. This is the natural prerequisite for the component-testing recommendation and reduces merge conflicts in the busiest files.
+- [MEDIUM] **Documentation accuracy — README.md and CLAUDE.md drift** — README.md claims 'Prisma 6' and 'React 18' (actual: Prisma 7.8.0, React 19.2.7) and points to 'eslint.config.js' (actual: eslint.config.mjs); CLAUDE.md says logAudit lives in src/utils/audit.ts (actual: src/services/audit.ts), lists utils as 'totp.ts, pdf.ts, email.ts, audit.ts' (actual: html-to-pdf.ts in utils, mailer.ts in services, no email.ts/pdf.ts/audit.ts), says 'admin/ # React 18' in the structure tree while its own tech-stack table says React 19, and cites '17 files'/'18 files / 247 tests' (actual: 25 files in src/**tests** plus theme.test.ts).
+  - Recommendation: One doc-sync pass: fix README versions and the eslint filename, correct CLAUDE.md's audit.ts path, utils listing, React-18 remnant and test counts. These docs are actively used as ground truth by tooling and agents, so drift here propagates into wrong code.
+- [LOW] **Repo hygiene — tracked .claude/settings.local.json** — .claude/settings.local.json is committed (git ls-files confirms) even though .gitignore lists it — it was tracked before the ignore rule was added, so ignore no longer applies and future machine-local permission edits will keep landing in commits. Current content is harmless (bash permission allowlists, no secrets); .claude/settings.json (hooks only) is fine to track.
+  - Recommendation: Run git rm --cached .claude/settings.local.json and commit; the existing .gitignore entry then takes effect. Keep settings.json tracked since the format-on-save and block-env hooks are useful shared config.
+- [LOW] **Repo hygiene — root directory clutter** — The repo root carries six release tarballs (app-ts-2.0.0…2.2.0.tar.gz, ~1 MB each), scratch outputs (npm-audit.json, npm-outdated.json, review_scope.txt, review_batches.json, frontend_Design_flaws.md, simon/plan_boha.pdf), and historical review reports (REVIEW\*.md, currently staged for deletion). All are gitignored or being removed, but they obscure the real project files and risk accidental tarball-of-a-tarball in releases.
+  - Recommendation: Move release archives to a gitignored releases/ folder (and update the release-process docs), delete or relocate one-off scan outputs to docs/ or a scratch dir, and finish committing the REVIEW\*.md deletions.
+- [LOW] **Dead configuration — unused path alias and stale ESLint ignore** — All three tsconfigs define the '@/_' → 'src/_' path alias but zero source files use it, and Vite has no matching resolve.alias so it could never work in the frontend anyway; eslint.config.mjs also ignores 'src/admin/bones/\*_' which no longer exists, and the blanket '_.config.ts' ignore leaves vite.config.ts/vitest.config.ts/prisma.config.ts unlinted.
+  - Recommendation: Either wire the alias properly (add resolve.alias to vite.config.ts and start using it for deep imports) or delete the paths blocks from all three tsconfigs; drop the bones ignore; consider linting the config files via the typescript-eslint node block.
+- [LOW] **Server module system — CJS forces an eval-import hack** — The server compiles to CommonJS, so src/server.ts loads ESM-only Vite via Function('return import("vite")')() — an eval-style escape hatch that defeats type checking and bundler analysis, and the same CJS choice drives 'as any' casting around the Vite middleware and the documented CJS/ESM test friction.
+  - Recommendation: Plan a server migration to ESM (module: nodenext, "type": "module" or .mts), which removes the eval hack, aligns with Fastify 5/Vitest defaults, and future-proofs against the growing set of ESM-only dependencies. Not urgent — it only bites in dev — but worth scheduling before more dynamic-import workarounds accumulate.
+- [LOW] **Environment validation — manual parsing instead of schema** — src/config/env.ts hand-rolls required()/parseInt with per-field fallbacks; the project already depends on Zod 4 but does not use it for env validation, so a typo like ACCESS_TOKEN_EXPIRY=15m silently becomes NaN→fallback rather than a boot error (a few fields like MAX_UPLOAD_SIZE guard this individually, most do not). The .env.example itself is excellent and complete vs env.ts.
+  - Recommendation: Define a Zod schema for the whole env (z.coerce.number() with bounds, enums for APP_ENV) and parse once at boot — same fail-fast behavior the codebase already mandates for request bodies, and it keeps .env.example verifiably in sync with one source of truth.
+- [LOW] **Test placement — theme.test.ts outside the test tree** — src/admin/theme.test.ts is the only test colocated with source; every other test lives in src/**tests** per the documented convention, and it is type-checked by tsconfig.app.json rather than tsconfig.test.json, so it follows different compiler settings than the rest of the suite.
+  - Recommendation: Either move it to src/**tests**/theme.test.ts for consistency, or — if adopting the component-testing recommendation — keep colocation as the new convention for frontend tests and document that split (server tests in **tests**, frontend tests colocated).
 
-**Verdict on structure:** This is a textbook layered monolith and the layering is followed consistently across the whole tree. The separation of concerns is _good_. The "mess" is not architectural — it's **(a) a handful of God-files, (b) missing tooling/hygiene scaffolding, (c) accumulated dead weight (deps + working-tree cruft), and (d) ~77 `any` escape hatches.** None of that requires re-architecting; it requires a cleanup pass. Recommendation: **keep the current core**; do not migrate to Next.js/separate repos — the unified Fastify-serves-SPA model is appropriate for an internal tool and a rewrite would cost far more than it returns.
+### Dependencies
 
-### [HIGH] No linter anywhere; formatter is unpinned and undeclared
+Overall dependency health is good: the stack is modern (Fastify 5, Prisma 7, React 19, Vite 8, Zod 4, Vitest 4) and ~19 of the 26 outdated packages are trivial minor/patch bumps clearable in one npm update pass. The npm audit total of 7 vulnerabilities (2 critical, 3 moderate, 2 low) is far less scary than it looks: both criticals come from `concurrently`, an UNUSED devDependency (no npm script references it — delete it and they vanish); the 3 moderates are one chain (prisma 7.x → @prisma/dev pinning vulnerable @hono/node-server) whose npm-suggested "fix" is a Prisma 6 downgrade you must NOT take — use an npm `overrides` entry for `@hono/node-server@^1.19.13` instead; the lows are an unpatched-upstream quill XSS already mitigated by the codebase's DOMPurify/cleanQuillHtml sanitization. Verified maintenance status (registry + web, June 2026): bcryptjs, node-cron, otpauth, nodemailer, puppeteer, react-quill-new and dnd-kit are all actively maintained — the only genuinely dormant package is the transitive quill core editor (last publish Jan 2025, open CVE), worth watching under its maintained react-quill-new wrapper. Two officially deprecated `@types` stubs (@types/dompurify, @types/bcryptjs) should be removed. Strategic upgrades to triage, none urgent: MUI 7→9 (double-major, codemods available), react-router-dom 6→7, TypeScript 5.9→6.0 (wait for toolchain support), and note puppeteer 25 is ESM-only + Node ≥22, which conflicts with the CommonJS server build — stay on the still-supported 24.x line until an ESM migration is planned.
 
-- There is **no ESLint config** (`eslint.config.*`/`.eslintrc` absent) and **no ESLint dependency**. A 77k-LOC TS/React codebase with no static lint is the single biggest hygiene gap — it's why 77 `any`s, unused vars, and hook-dep mistakes go uncaught. The app tsconfig even sets `noUnusedLocals: false` / `noUnusedParameters: false`, so the compiler won't flag dead code either.
-- `.claude/hooks/format-on-save.js` runs `npx prettier --write`, but **prettier is not in `devDependencies`** and there is **no `.prettierrc`**. Formatting is therefore whatever an ad-hoc `npx`-fetched Prettier defaults to — not reproducible, not enforced in CI.
-- **Recommend:** add `eslint` + `typescript-eslint` + `eslint-plugin-react-hooks` (the hooks plugin alone would catch a class of frontend bugs), add `prettier` as a real devDep with a committed config, and wire both into an npm script / pre-commit.
-
-### [HIGH] Test sources are never type-checked
-
-`tsconfig.server.json` excludes `src/__tests__`, and `tsconfig.app.json` does not include it — so **no project type-checks the test files**. `npx tsc -b` (the documented gate) silently skips 19 test files. Type errors in tests only surface at `vitest run`. Add a `tsconfig.test.json` (or include tests in a checked project) so the gate actually covers them.
-
-### [MEDIUM] God-files — a few modules carry far too much
-
-Largest files by LOC: `routes/admin/warehouse.ts` **2399**, `pages/InvoiceDetail.tsx` **2243**, `pages/OfferDetail.tsx` **2059**, `services/attendance.service.ts` **1700**, `pages/CompanySettings.tsx` **1503**, `hooks/useAttendanceAdmin.ts` **1402**, `pages/Settings.tsx` **1354**, `pages/Attendance.tsx` **1266**. These are hard to hold in context, hard to review, and the most likely homes for latent bugs. `routes/admin/warehouse.ts` in particular should be split per sub-entity (items/receipts/issues/reservations/inventory) the way the _pages_ already are. (Per-file findings below will flag specific seams.)
-
-### [MEDIUM] ~77 `any` escape hatches erode the strict-mode guarantee
-
-`grep` finds 77 `as any` / `: any` in `src`. CLAUDE.md explicitly warns that typing `authData as any` hides the `roleName` vs `role` bug — yet route files (`plan.ts`, `projects.ts`, `quotations.ts`, `sessions.ts`, `trips.ts`) and `services/audit.ts` use `any`. Each is a hole where the type system stops helping. Most are `(request.params as any).id` / `(request.body as any)` which a small set of typed helpers would remove. Flagged per-file where they hide real risk.
-
-### [MEDIUM] Dependency drift + 8 known vulnerabilities (`npm audit`)
-
-`npm audit`: **8 vulns (6 moderate, 2 low)**. Notable: `quill` 2.0.3 XSS via HTML-export (pulled by `react-quill-new`; partly mitigated here because rich-text is DOMPurify-sanitized on both render and PDF paths), `file-type` ASF infinite-loop DoS, `react-router` open-redirect via protocol-relative `//` path, plus `ws`/`qs`/`brace-expansion` transitive DoS/disclosure. Most are `npm audit fix` (non-breaking); `quill` and `file-type` need a major bump.
-Major versions behind (review before jumping — all breaking): **React 18→19**, **MUI 7→9**, **@mui/x-date-pickers 8→9**, **Prisma 6→7**, **react-router 6→7**, **TypeScript 5.9→6**, **file-type 16→22 (ESM-only)**, **@fastify/multipart 9→10**. None are urgent for an internal app, but Prisma 6→7 and React 18→19 are the strategically important ones to plan.
-
-### [MEDIUM] Dead dependencies (classic multi-AI residue)
-
-Verified zero imports in `src`: **`react-datepicker`** (replaced by `@mui/x-date-pickers` — remove), **`hi-base32`** (TOTP now via `otpauth` — remove), **`@types/mysql`** (no `mysql` package used; Prisma is the driver — remove). Removing these shrinks the install and the audit surface. (`qrcode`, `leaflet`, `file-type`, `dompurify`, `nodemailer`, `@dnd-kit` are all genuinely used.)
-
-### [MEDIUM] No committed README; `.env.example` is stale
-
-- **No README is tracked** (`README.md` exists only as an untracked working-tree file). A production app should have a committed README covering setup/run/deploy. (CLAUDE.md is excellent and partly compensates, but it's agent-facing, not a project README.)
-- **`.env.example` is missing many real env vars** that `config/env.ts` reads: `ANTHROPIC_API_KEY`, `NAS_FINANCIALS_PATH`, `NAS_OFFERS_PATH`, `SMTP_FROM_NAME`, `INVOICE_ALERT_EMAIL`, `RATE_LIMIT_*`, `TRUST_PROXY`, `TOTP_ALGORITHM/DIGITS/PERIOD`, `LOGIN_TOKEN_EXPIRY_MINUTES`. A fresh checkout can't discover these without reading source.
-
-### [LOW] `.gitignore` lets build/junk leak into the working tree
-
-`.gitignore` covers `node_modules/dist/dist-client/.env*` but **not** `*.tsbuildinfo`, `*.bak`, or stray artifacts. The working tree currently holds untracked cruft: `tsconfig.app.tsbuildinfo`, `tsconfig.server.tsbuildinfo`, `prisma/schema.prisma.bak`, `simon/plan_boha.pdf`, `.playwright-mcp/`, `frontend_Design_flaws.md`, `plan-*.png` screenshots. None are committed (good), but add `*.tsbuildinfo` and `*.bak` to `.gitignore` and clear the loose files so the tree reads clean.
-
-### [LOW] Per-request auth does several uncached DB round-trips
-
-`verifyAccessToken` → `loadAuthData` runs on **every** authenticated request and issues: user+roles+permissions join, a `company_settings` lookup for `require_2fa`, and — for admins — a **full `permissions` table scan** (`findMany`) every call. Correct, but it's 2–3 queries per request with zero caching. Fine at current scale; a short-TTL in-memory cache of permissions-by-role would cut DB load materially if traffic grows. (Noting once here rather than per-route.)
-
-### Positives worth preserving
-
-Timing-safe login (dummy-bcrypt on every failure path), refresh-token **rotation** with `replaced_by_hash` reuse-detection and `FOR UPDATE` locking, hashed (not plaintext) refresh tokens, strict secret validation at boot (64-hex JWT/TOTP keys, port range), health check before rate-limit, consistent `{success,error}` envelope, DOMPurify on both render and PDF paths, prod-only HSTS+CSP, and a genuinely thorough CLAUDE.md. The conventions doc + the 2026-06-06 audit show the team already fights entropy deliberately.
+- [CRITICAL] **concurrently (+ shell-quote)** — Both critical audit findings (GHSA-w7jw-789q-3m8p, shell-quote command injection CVSS 8.1, via concurrently 9.2.1) sit in a devDependency that is completely unused — no npm script in package.json references concurrently (the dev scripts run tsx/vite separately); the only 'concurrently' matches in src/ are the English word in comments.
+  - Recommendation: Remove concurrently from devDependencies entirely (zero migration risk — it is dead weight). If it is ever wanted again, install concurrently@10.0.3 which has the patched shell-quote. This single deletion clears both critical audit entries.
+- [MEDIUM] **prisma / @prisma/dev / @hono/node-server** — All 3 moderate audit findings are one chain: prisma 7.x ships @prisma/dev (<=0.24.8) which pins vulnerable @hono/node-server <1.19.13 (GHSA-92pp-h63x-v22m, middleware bypass via repeated slashes in serveStatic). Exposure is the Prisma CLI dev tooling, not the production runtime query path. npm audit's suggested fix is a DOWNGRADE to prisma 6.19.3 (semver-major backwards) — unacceptable, the app is built on the Prisma 7 Rust-free client + @prisma/adapter-mariadb.
+  - Recommendation: Do NOT take npm's downgrade fix. Add an npm overrides entry in package.json: "overrides": { "@hono/node-server": "^1.19.13" }, and track prisma/prisma#29605 for an upstream @prisma/dev fix. Migration risk: trivial (one package.json field + reinstall).
+- [MEDIUM] **@types/dompurify** — Officially deprecated on npm: "This is a stub types definition. dompurify provides its own type definitions, so you do not need this installed." dompurify >=3.2 bundles its own types; the stub is dead weight and can shadow/conflict with the real types.
+  - Recommendation: Remove @types/dompurify from devDependencies. Migration risk: none — run npm run typecheck after removal to confirm.
+- [MEDIUM] **@types/bcryptjs** — Officially deprecated on npm: "This is a stub types definition. bcryptjs provides its own type definitions." Worse, the installed stub is ^2.4.6 (2.x API) while bcryptjs 3.0.3 is the runtime — the stale stub can mask the bundled 3.x typings.
+  - Recommendation: Remove @types/bcryptjs from devDependencies. Migration risk: none — bcryptjs 3.x ships correct types; verify with npm run typecheck.
+- [MEDIUM] **quill (via react-quill-new)** — Two-part finding. (1) Audit low: quill 2.0.3 has an unpatched XSS in the HTML export feature (GHSA-v3m3-f69x-jf25 / CVE-2025-15056); NO fixed quill release exists, and npm's 'fix' is a downgrade of react-quill-new to 3.7.0 — not a real fix. The codebase already mitigates this (server-side DOMPurify via jsdom, frontend sanitization before dangerouslySetInnerHTML, cleanQuillHtml on all PDF routes). (2) Maintenance: quill core has had no release since Jan 2025 and Snyk flags it as possibly discontinued; the react-quill-new wrapper itself IS actively maintained (3.8.3, Feb 2026).
+  - Recommendation: Keep react-quill-new 3.8.3 and the existing sanitization discipline (do not take the downgrade 'fix'). Watch quill core: if it stays dormant through an open CVE for another cycle, plan a medium-term migration to TipTap or Lexical — that is a LARGE refactor (RichEditor/RichEditorRoot/RichTextView components, Quill Delta/HTML content model, existing stored rich-text in invoices/quotations/orders), so it should be a deliberate project, not a casual swap.
+- [MEDIUM] **puppeteer** — Behind on two levels: 24.40.0 → 24.43.1 (patch, safe) and major 25.1.0 available. Puppeteer is very actively maintained (verified, 25.1.0 published May 2026), but v25 is ESM-ONLY, requires Node >=22, and makes executablePath/defaultArgs async — this directly conflicts with the server build, which compiles to CommonJS (tsconfig.server.json, "type": "commonjs").
+  - Recommendation: Bump within 24.x to 24.43.1 now (safe). Defer v25 until/unless the server build migrates to ESM (or use dynamic import() shims); treat the v25 jump as HIGH migration risk and bundle it with any future CJS→ESM move. The 24.x line is still supported.
+- [MEDIUM] **@mui/material + @mui/x-date-pickers** — @mui/material 7.3.11 → 9.1.0 and @mui/x-date-pickers 8.29.0 → 9.4.0. MUI skipped v8 for core to re-align majors with MUI X. v9 removes previously-deprecated APIs and system props (sx only), changes Grid (no direction="column"), tweaks ListItemIcon min-width, ~3% smaller bundle; official codemods and an Upgrade-to-v9 guide exist. The app's entire admin UI kit (src/admin/ui/, theme.ts, GlobalStyles.tsx) sits on MUI v7, so the surface is wide.
+  - Recommendation: Plan a dedicated upgrade task: run the MUI v9 codemods, upgrade core and x-date-pickers together (one shared major), then visually regression-test the ui-kit showcase route and dense tables. Moderate migration risk, not urgent — v7 still works fine; do it before v7 drops out of support.
+- [MEDIUM] **react-router-dom** — 6.30.4 → 7.17.0 (major). v6 is in maintenance mode; v7 is the active line (package consolidation into react-router, react-router-dom kept as a thin re-export). The app uses classic <Routes>/lazy pages in AdminApp.tsx, and already satisfies v7's React 18+ requirement (React 19).
+  - Recommendation: Upgrade path: enable the v6 future flags first (v7_startTransition, v7_relativeSplatPath, etc.) on 6.30.x, confirm no warnings, then bump to v7 and optionally switch imports to "react-router". Moderate, mostly-mechanical migration risk for a non-data-router app like this one.
+- [LOW] **typescript** — 5.9.3 → 6.0.3 (major). TS 6.0 changes nine compiler defaults (strict by default — this repo is already strict; rootDir inference now '.', types:[] no longer auto-crawls @types, moduleResolution classic removed, ES5 target deprecated, esModuleInterop always on). Toolchain (typescript-eslint 8.61, vite, vitest) must also declare TS 6 support.
+  - Recommendation: Hold on 5.9.x until typescript-eslint and the Vite/Vitest toolchain officially support TS 6, then migrate using the ts5to6 codemod (npx @andrewbranch/ts5to6) and re-verify the three tsconfig projects (server/test/solution). Moderate config-level risk, low urgency.
+- [LOW] **@fastify/multipart, @fastify/rate-limit** — @fastify/multipart 9.4.0 → 10.0.0 and @fastify/rate-limit 10.3.0 → 11.0.0 — both new majors; Fastify plugin majors historically bump minimum Fastify/Node versions with small API changes (e.g. multipart v10 changes saveRequestFiles return values). Detailed breaking-change lists were not in release summaries found.
+  - Recommendation: Read the GitHub release notes for both before bumping; expected low migration risk on Fastify 5, but verify the multipart upload route and rate-limit config against the changelogs, and run the NAS file-manager tests after.
+- [LOW] **minor/patch batch (19 packages)** — Safe minor/patch updates available: @anthropic-ai/sdk 0.102.0→0.104.0, @tanstack/react-query 5.100.5→5.101.0, @types/jsdom 28.0.1→28.0.3, @types/node 25.5.0→25.9.2, @vitejs/plugin-react 6.0.1→6.0.2, date-fns 4.1.0→4.4.0, dompurify 3.4.5→3.4.8, dotenv 17.3.1→17.4.2, framer-motion 12.38.0→12.40.0, jsdom 29.0.2→29.1.1, mariadb 3.5.2→3.5.3, nodemailer 8.0.7→8.0.10, otpauth 9.5.0→9.5.1, prettier 3.8.3→3.8.4, puppeteer 24.40.0→24.43.1 (within-range), tsx 4.21.0→4.22.4, vite 8.0.13→8.0.16, vitest 4.1.0→4.1.8, zod 4.3.6→4.4.3.
+  - Recommendation: One npm update pass, then the standard gates (tsc -b --noEmit, npm run build, npx vitest run, npm run lint). @anthropic-ai/sdk is 0.x so skim its 0.103/0.104 changelog for the Odin extract-invoices structured-output path, but risk is low.
+- [LOW] **@types/nodemailer** — Types package (7.0.11) is a full major behind the installed runtime (nodemailer 8.0.x); @types/nodemailer 8.0.0 exists. Mismatched type majors can hide real API differences in src/utils/email.ts.
+  - Recommendation: Bump @types/nodemailer to ^8.0.0 alongside the nodemailer patch bump. Trivial risk; typecheck confirms.
+- [LOW] **bcryptjs** — Verified actively maintained (3.0.3, 2026 activity) and NOT deprecated — no forced action. Context: it is pure-JS (~3-4x slower than native bcrypt), and OWASP's current guidance puts Argon2id first with bcrypt 'acceptable'. Existing user hashes are bcrypt (including PHP-legacy $2y$), so any swap needs a rehash-on-login transition.
+  - Recommendation: Keep bcryptjs for now (zero native-build hassle on the Windows dev + Linux prod mix). Optional long-term hardening: migrate to argon2 (npm 'argon2', current 0.44.0) with verify-old/rehash-new on login. Migration risk: moderate (dual-verify logic, native dependency in prod deploy).
+- [LOW] **node-cron** — Verified maintained (4.2.1, 2026 activity) — not abandoned. However croner (current 10.0.1) is the more robust 2026 choice: TypeScript-native, zero deps, Intl-based timezone/DST handling, and a catch option so job errors aren't silently swallowed. Relevant here because the app pins TZ=Europe/Prague where DST transitions can shift naive cron schedules, and the codebase has a 'never swallow errors' rule.
+  - Recommendation: No urgent action. If cron-time DST correctness or job error handling ever bites, swap to croner@10 — cron expression syntax is compatible and the scheduler surface in this app is small. Low migration risk.
+- [LOW] **otpauth, nodemailer, puppeteer (maintenance verification)** — All three flagged-for-checking packages verified healthy via registry + web (June 2026): otpauth 9.5.1 (hectorm, active releases, RFC 6238 — matches the TOTP module), nodemailer 8.0.10 (published May 2026, active), puppeteer 25.1.0 (published May 2026, very active). None deprecated or abandoned.
+  - Recommendation: No replacements needed; just take the patch/minor bumps listed in the batch finding (puppeteer stays on 24.x per its separate finding).
+- [LOW] **@dnd-kit/\* and leaflet (staleness watch)** — @dnd-kit/core last npm publish Dec 2024, but 2026 ecosystem sources consistently describe dnd-kit as actively maintained and still the React drag-and-drop default (used in 3 detail pages here). leaflet is on 1.9.4 (last stable era 2023) with v2 in progress upstream; used on a single page (AttendanceLocation.tsx). Neither is deprecated.
+  - Recommendation: No action now; re-check both at the next dependency review. If dnd-kit goes truly dormant, Atlassian's pragmatic-drag-and-drop is the credible replacement (headless, more DIY). Leaflet 2.0 will be a deliberate migration when it ships stable.
+- [LOW] **framer-motion (weight, not redundancy)** — Used in 15 files, but mostly for simple entrance/fade/stagger animations (PageEnter, PageHeader, dashboard widgets, Odin thread) — the full framer-motion bundle (~30-40 kB gz) is heavy for that usage profile. It is genuinely used, so removal is not recommended; no competing animation lib is installed (no duplication).
+  - Recommendation: Optional optimization: adopt framer-motion's built-in LazyMotion + m components (domAnimation feature set) to cut the animation bundle to ~6 kB, or convert the simplest fades to CSS transitions. Low risk, purely a bundle-size win; respects the existing useReducedMotion handling.
+- [LOW] **dependency placement hygiene (@types/jsdom, dotenv)** — (1) @types/jsdom sits in dependencies instead of devDependencies, so the prod install (npm install --omit=dev) still pulls a types-only package. (2) dotenv 17 is fine and maintained, but Node >=20 supports --env-file natively; dotenv is now optional weight (kept useful here by the .env/.env.test switching workflow).
+  - Recommendation: Move @types/jsdom to devDependencies (trivial, no risk). Keep dotenv unless someone wants to slim prod deps — switching to node --env-file would touch the start script and test setup, so only do it deliberately.
+- [LOW] **date-fns (redundancy check — clean)** — Date-library redundancy check passed: date-fns v4 is the only date library (no moment/dayjs/luxon duplication) and it is REQUIRED as the @mui/x-date-pickers adapter (AdapterDateFns with cs locale in MuiProvider/DateField/MonthField/TimeField). Not replaceable by native code while MUI pickers are in use.
+  - Recommendation: No action — this is the correct setup. Take the 4.1.0 → 4.4.0 minor bump with the batch.
 
 ---
 
-## src/server.ts
+# Per-file findings
 
-- [LOW] `Function('return import("vite")')()` indirect-eval hack (line 160) to load ESM Vite from the CJS bundle — intentional, brittle. Otherwise clean: plugin order, health check before rate-limit, graceful shutdown.
+## .claude/hooks/block-env.js
 
-## src/config/env.ts
+- [HIGH] (line 10-11) Block decision never takes effect: hook prints {decision:'block'} JSON to stdout then exits 1 — Claude Code only parses stdout JSON on exit 0 and only blocks on exit 2 (reason read from stderr), so exit 1 is treated as a non-blocking error, stdout is ignored, and the .env edit proceeds silently; fix by exiting 0 with the JSON or exiting 2 with the reason on stderr. _(verified)_
+- [LOW] (line 13) Empty `catch {}` swallows malformed-hook-input errors with no log and fails open (edit allowed), violating the repo rule that silent expected-condition catches require an explanatory comment.
 
-- [LOW] Global `Date.prototype.toJSON` override (lines 14-22) — documented PHP-compat gotcha; app-wide. Strong boot-time secret/port validation. Clean.
+## .claude/hooks/format-on-save.js
 
-## src/config/database.ts
+- [MEDIUM] (line 10) Shell-injection risk: filePath from hook JSON input is interpolated unescaped into an execSync shell string (`npx prettier --write "${filePath}"`); filenames containing shell metacharacters (POSIX: quotes/backticks/$( ); cmd.exe: %VAR% expansion) execute arbitrary commands with no permission prompt — use execFileSync with an argument array.
+- [LOW] (line 12) Empty `catch {}` plus stdio:'ignore' silently swallows every hook failure (prettier errors, timeouts) with no comment marking it as an expected-condition catch.
 
-- Clean — single PrismaClient singleton.
+## .claude/settings.json
 
-## src/middleware/security.ts
+- [LOW] (line 9, 22) Hook commands use relative paths (`node .claude/hooks/...`) instead of "$CLAUDE_PROJECT_DIR"; hooks run in the session's current directory, so if cwd leaves the repo root both hooks fail non-blockingly and the .env guard + auto-format silently stop working.
 
-- [LOW] CSP/HSTS prod-only (line 18); `style-src 'unsafe-inline'` required by Emotion; no `report-uri`. Clean.
+## .claude/settings.local.json
 
-## src/middleware/auth.ts
+- [LOW] (line 4-9) Dead permission allowlist: lines 4-5 have backslashes escaped away (`D:cortexboha-appresources`) so the rules can never match a real command, and lines 4-5/8-9 all target the legacy boha-app PHP repo rather than this project — stale entries that should be pruned.
 
-- Clean — correct `reply.sent` short-circuit, admin bypass via `roleName`.
-
-## src/utils/response.ts
-
-- Clean — envelope helpers + `parseId` (NaN/≤0 → 400).
-
-## src/services/auth.ts
-
-- [MEDIUM] Refresh-token rotation rejects replaced/expired tokens but does NOT revoke the token family on detected reuse (lines 273-280) — no breach containment.
-- [LOW] `loadAuthData` runs on every request (2-3 queries; admin full `permissions.findMany` scan). Strong otherwise (timing-safe, hashed tokens, FOR UPDATE, lockout).
-
-## src/services/ai.service.ts
-
-- [LOW] `extractInvoice` `JSON.parse` of model output unguarded (line 351) — low risk with json_schema. Budget/cost ledger correct.
-
-## src/routes/admin/ai.ts
-
-- [LOW] `extract-invoices` swallows per-file failure / budget-exhausted-mid-batch into partial success, no truncation signal (lines 130-131). Otherwise clean (guard, parseId/parseBody, per-user ownership, audit).
-
-## src/routes/admin/attendance.ts
-
-- [MEDIUM] Many handlers use raw `reply.send` envelope instead of `success()`/`paginated()` (lines 32,108,118,128,142,165-239).
-- [LOW] `action=project_logs` (line 189) — no ownership check (location path does enforce it); `Number(query.year)` NaN fallbacks.
-
-## src/routes/admin/audit-log.ts
-
-- [MEDIUM] `Number(query.user_id)` (line 33) → NaN → Prisma 500 instead of 400.
-- [LOW] `date_to`+`"T23:59:59"` (line 40) — malformed date → 500.
-
-## src/routes/admin/auth.ts
-
-- Clean — TOTP replay protection, single-use login token, httpOnly/secure/sameSite=strict cookie, rate limits, audit.
-
-## src/routes/admin/bank-accounts.ts
-
-- Clean — `settings.banking` guard, parseId/parseBody, existence checks, audit.
-
-## src/routes/admin/company-settings.ts
-
-- [LOW] Extra `findFirst` for `has_logo` (302-307, deliberate); request-time `require(package.json)`; PUT `Number()` without NaN re-guard (481). Clean (magic-byte MIME sniff, race-safe create).
-
-## src/routes/admin/customers.ts
-
-- [MEDIUM] GET `/` raw `reply.send` envelope (100-104) instead of `paginated()`. Otherwise clean (guards, FK-check before delete, allow-listed sort, parameterized search).
-
-## src/routes/admin/dashboard.ts
-
-- [MEDIUM] N+1: `today_plan` per-cell `plan_categories.findUnique` (55-67); bounded but should be one `findMany`.
-- [LOW] `created_at ?? ""` dead fallback (314). Otherwise clean (gated, Promise.all, parameterized $queryRaw).
-
-## src/routes/admin/leave-requests.ts
-
-- [MEDIUM] GET `/` raw `reply.send` envelope (57-61).
-- [LOW] Approval path drops `reviewer_note` (302-309) though rejection saves it. Otherwise clean (transactional approval, owner+pending cancel, audit).
-
-## src/routes/admin/profile.ts
-
-- Clean — current-password verify, email-uniqueness in tx (409), tokens invalidated on pwd change, self-scoped, audit.
-
-## src/routes/admin/invoices.ts
-
-- [LOW] GET `/` raw `reply.send` envelope (62-66); module-scoped `markOverdueInvoices` throttle can double-run under concurrency (30-39, self-correcting). Otherwise clean.
-
-## src/routes/admin/invoices-pdf.ts
-
-- [LOW] `JSON.parse(settings.custom_fields)` (451) has no try/catch → malformed JSON makes whole PDF 500; `save=1` raw envelope (1073); loose typing. Note: `notes` IS DOMPurify+cleanQuillHtml sanitized (521).
-
-## src/routes/admin/offers-pdf.ts
-
-- [LOW] `save=1` raw envelope (761); local `cleanQuillHtml` strips only `javascript:` (not data:/vbscript:) — defense-in-depth only (DOMPurify first, 357). Clean.
-
-## src/routes/admin/orders.ts
-
-- [MEDIUM] From-quotation multipart parses `fields.quotationId` with raw `parseInt` (123) not schema/parseId.
-- [LOW] Raw `request.body` casts (203,313); unbounded multipart field/file count (only fileSize limited). Otherwise solid.
-
-## src/routes/admin/orders-pdf.ts
-
-- [HIGH] POST renders an official "Order Confirmation" PDF entirely from client-supplied `body.items` (304-312) — `orders.view` holder can fabricate descriptions/prices not reflecting stored data (downloadable, not persisted → limited impact; trust/authz concern).
-- [LOW] Deprecated `.passthrough()` (30); loose untyped `body.lang`/`applyVat`; `(order as Record).payment_method` cast (387). `notes` sanitized (409).
-
-## src/routes/admin/quotations.ts
-
-- [MEDIUM] GET `/:id` second `quotations.findUnique` for lock info right after `getOffer(id)` (123-129) — redundant query per detail view.
-- [LOW] `(result as any).status` cast (286); empty `catch {}` on NAS PDF delete commented "Non-fatal" but does NOT log (321-323). Lock/heartbeat/unlock scoped to `locked_by=userId` (correct).
-
-## src/routes/admin/received-invoices.ts
-
-- [HIGH] JSON single-create computes `vat_amount=(amount*vat_rate)/100` (394-397) — treats GROSS as net, violating gross-VAT convention and INCONSISTENT with multipart (297) + update (467) paths using `vatFromGross`. Same invoice → different VAT by entry path.
-- [LOW] GET `/` raw envelope (89-93); `stats` `sumCzk` sequential + throws on unknown currency → 500 (135); multipart create loops per-file with no transaction (partial-success on failure).
-
-## src/routes/admin/scope-templates.ts
-
-- [MEDIUM] No `logAudit` on ANY mutation (create/update/delete of scope + item templates) — audit-convention violation.
-- [MEDIUM] DELETE `?action=item&id=X` uses `Number(query.id)` no NaN/existence guard (134-139) → 500; no row-exists/`is_deleted` check.
-- [LOW] `?action=` dispatch mixes two entities in one handler; `Number(body.id)`/`Number(query.id)` instead of validated ids.
-
-## src/routes/admin/plan.ts
-
-- [LOW] `(result.data as any).id`/`(result.oldData as any)` audit casts (256,310,334,361,392,416). Otherwise clean — guards on every route, parseId/parseBody, audit on every mutation, `isAdminLike` reads `roleName`, 92-day range cap.
-
-## src/routes/admin/project-files.ts
-
-- [LOW] Folder-create (120) and move (236) read raw `request.body` bypassing parseBody (manually String-coerced). Path traversal delegated to `resolveProjectPath` (sound). Clean.
-
-## src/routes/admin/projects.ts
-
-- [MEDIUM] GET `/` raw envelope (44-48).
-- [LOW] DELETE reads unvalidated body for `delete_files` (182-183); `(result as any).status` casts; POST `/:id/notes` does NOT `logAudit` though note-delete does (126-148) — inconsistent audit.
-
-## src/routes/admin/roles.ts
-
-- [HIGH] POST `/` no uniqueness guard on `roles.name` and no admin-only gate — a non-admin `settings.roles` holder can create a role (even named `admin`) and attach ANY permission_ids → privilege escalation (59-98). PUT `/:id` can rewrite the `admin` role's permissions (no `name==="admin"` guard like DELETE) → escalation/lockout (102-138).
-- [MEDIUM] Role insert + permission assignment in separate transactions (67-73 vs 76-86) — partial failure leaves orphan role.
-
-## src/routes/admin/sessions.ts
-
-- Clean — ownership-scoped queries, audit on terminate/terminate-all, current-session via `hashToken`. No IDOR.
-
-## src/routes/admin/totp.ts
-
-- [HIGH] `/enable` verifies the new secret with hardcoded SHA1/6/30 (87-94) not `config.totp.*` — config divergence → enrolled secrets verify under different params than login → lockout.
-- [MEDIUM] `/backup-verify` bcrypt-compares every code, no early-exit on match (307-312) — N bcrypt ops/attempt.
-- [LOW] `/enable` change-flow (2FA on) needs only a live code, not password (65-76); redundant dynamic re-imports shadow `config` (363-370).
-
-## src/routes/admin/trips.ts
-
-- [MEDIUM] GET `/users` (83) guarded only by `requireAuth` — any authenticated user enumerates all active users. Information disclosure.
-- [MEDIUM] GET `/` raw envelope (73-77).
-- [LOW] In-handler permission checks run after parseBody; POST create unconditionally sets `vehicle.actual_km=end_km` (244-247) — can regress odometer (PUT/DELETE recompute via MAX). PUT/DELETE ownership checks correct.
-
-## src/routes/admin/users.ts
-
-- [LOW] Non-admin escalation guard strips `role_id`/`is_active` (109-114, good); bounded `as Parameters<...>` cast (121); forced logout on pwd change not separately audited. Clean (parseId/parseBody/guard/audit, paginated used).
-
-## src/routes/admin/vehicles.ts
-
-- [MEDIUM] GET `/` guarded only by `requireAuth` (15) — any authenticated user lists all vehicles + stats; mutations need `vehicles.manage`. Read should require a view permission. Otherwise clean (single groupBy, delete blocks linked trips).
-
-## src/routes/admin/warehouse.ts
-
-- [HIGH] `confirmIssue` locks only the `sklad_issues` row, not item/batch (service:523) — two different draft issues selecting the same FIFO batch confirm concurrently, both read-modify-write `batch.quantity` -> lost update, negative stock, double-issue. Same gap in `confirmInventorySession`.
-- [HIGH] FIFO batch selection at issue create/update (1496-1499,1622-1625) runs with no lock, persists chosen batch on draft; availability re-checked only at confirm -> wide TOCTOU/oversell.
-- [HIGH] Reports stock-status/project-consumption/movement-log/below-minimum have NO pagination + per-item N+1 (3 sequential aggregates/item; 629-646,2174-2306).
-- [MEDIUM] PUT receipts/issues/inventory-sessions do deleteMany+createMany on lines with NO $transaction (1150-1164,1660-1673,2090-2098) -> failure leaves draft with no lines.
-- [MEDIUM] Attachment save: NAS write then DB insert, no compensating delete (orphan on DB failure); confirm does not verify batch.item_id===line.item_id (wrong item decremented); received_by overwritten at confirm (service:350).
-- [MEDIUM] 2399-line file bundles 8 sub-entities + inline mid-file multipart register (963) — split per sub-entity.
-- [LOW] Unvalidated query.status / Number(query.x) filters; pervasive Record-cast querystrings. Every handler guarded, tiers consistent, attachment DELETE ownership-checked — no missing-guard/IDOR.
-
-## src/services/attendance.service.ts
-
-- [HIGH] `lockUserRow` uses `tx.$executeRaw` for a bare SELECT ... FOR UPDATE (85) — $executeRaw is for write statements; the punch/switch concurrency lock may not reliably hold. Should be `tx.$queryRaw`.
-- [HIGH] `getBalances` N+1: one `leave_balances.findFirst` per user in a loop (491), unbounded.
-- [MEDIUM] `createLeave` books a Dec->Jan range entirely against the start year (getFullYear, 1261); `getStatus` runs 5 independent queries serially.
-- [LOW] `deleteAttendance` (1694) has no ownership param (unlike updateAttendance); hardcoded 160 vacation default x3; ~1700-line file should be split.
-
-## src/services/audit.ts
-
-- [LOW] `safeJsonReplacer` duck-types Prisma Decimal via method presence (14-19) — instanceof would be precise. Failure caught+logged. Clean.
-
-## src/services/exchange-rates.ts
-
-- [HIGH] `fetch(url)` (33) has NO timeout/AbortController — a hung CNB endpoint blocks every awaiting caller indefinitely.
-- [MEDIUM] Global single `rateCacheTime` (14,22-24) — a hit on one key refreshes TTL for ALL keys; date-specific entries can outlive TTL; stale-fallback only checks today.
-- [LOW] No validation data.rates is an array before iterating (39).
-
-## src/services/invoice-alerts.ts
-
-- [MEDIUM] Created-invoice alert amount uses only subtotal (net, 92-95) while received invoices show gross — inconsistent; per-invoice `invoice_alert_log.findUnique` N+1 (81,142).
-- [LOW] Dead/identical ternary branches (232-239); sequential unguarded create loop can re-fire alerts; escapeHtml omits the apostrophe char.
-
-## src/services/invoices.service.ts
-
-- [MEDIUM] Three divergent money/VAT implementations: computeInvoiceTotals (47-74), invoiceTotalWithVat (164-196), stats VAT loop (264-270, no per-line rounding) — inconsistent totals risk.
-- [MEDIUM] `getInvoiceStats` serializes many toCzk awaits (247-295) — should Promise.all; createInvoice/updateInvoice take body: Record<string,any> with unchecked `as InvoiceItemInput[]` casts.
-- [LOW] `deleteInvoice` derives year from invoice_number.split("/")[1] (497) -> wrong sequence released for non-standard numbers; getInvoice returns null not {error,status}; paid_date settable on non-paid invoice (463).
-
-## src/services/leave-notification.ts
-
-- [LOW] `formatDate` try/catch ineffective — new Date(invalid) returns Invalid Date, never throws (13-18). Header injection mitigated via sanitizeHeaderValue; send failure logged. Clean.
-
-## src/services/mailer.ts
-
-- [MEDIUM] Transport hardcoded to local sendmail /usr/sbin/sendmail (5-9) — Linux-only, no SMTP fallback; on hosts without the binary every send silently fails (console.error only).
-- [LOW] `to` not validated/sanitized for CRLF (11) — nodemailer guards most.
-
-## src/services/system-settings.ts
-
-- [LOW] JSON.parse of vat-rates/currencies (56,61) no shape validation; process-local cache won't propagate cross-instance within 60s TTL. Two empty catches are commented expected-condition guards (OK). Clean.
-
-## src/services/nas-file-manager.ts
-
-- [MEDIUM] TOCTOU between resolveProjectPath validation (701-713) and the later fs op on the returned path — a symlink swapped into a path component could bypass the guard (low risk on a trusted share); ".." matched as literal substring (679, contained by prefix check).
-- [LOW] createProjectFolder sync/non-atomic (idempotent); MIME gate passes type-less files (SVG served as attachment w/ nosniff -> mitigated); collision suffix loop can yield name_1_2.
-
-## src/services/nas-financials-manager.ts
-
-- [MEDIUM] Fully synchronous fs over a network share on the request path (39-73,81+) — slow/hung NAS blocks the event loop.
-- [LOW] isConfigured() does mkdirSync as a predicate side effect (24); saveIssuedInvoicePdf skips isConfigured() (asymmetry). resolveSafePath guard correct.
-
-## src/services/nas-offers-manager.ts
-
-- [HIGH] Five fully-silent empty-catch blocks, no log/comment (24,46,59,76,111) — violates never-swallow rule; sibling financials manager logs all of them -> failed offer-PDF save/delete is invisible.
-- [LOW] deleteOfferPdf readdir/rmdir swallowed (covered above); isConfigured() mkdir side effect. resolveSafePath correct.
-
-## src/services/numbering.service.ts
-
-- [MEDIUM] getNextSequence first-of-year INSERT race (61-75) -> @@unique([type,year]) P2002 as 500 instead of retry.
-- [MEDIUM] releaseSequence (116-158) SELECT-then-UPDATE with no transaction/lock/tx param — concurrent delete+create can lose a decrement or decrement an in-use number (gap/dup).
-- [LOW] releaseSequence reconstructs highest number from current settings (144-149); changed pattern -> no-op -> gap.
-
-## src/services/offers.service.ts
-
-- [MEDIUM] createOffer TOCTOU: isOfferNumberTaken runs BEFORE the tx (162-167), create inside does not re-check -> concurrent dup numbers (orders.service fixed this).
-- [LOW] deleteOffer never calls deleteOfferPdf -> orphaned PDF on NAS; pervasive any in enrich/list money math.
-
-## src/services/orders.service.ts
-
-- [LOW] enrichOrder/getOrder treat projects as array projects?.[0] (60,151) — confirm cardinality; status->project-status sync duplicated verbatim in both update branches (525-538 & 572-585); deleteOrder FK guard runs outside the tx (599,617-634) -> narrow re-intro window. Tx boundaries otherwise correct.
-
-## src/services/plan.service.ts
-
-- [MEDIUM] N+1 per mutation: resolvePlanLabels(2q)+resolveCategoryLabel(1q) after each write for the audit description (483-489); bulkCreateEntries multiplies it.
-- [LOW] createEntry cap check outside any tx (464) — concurrent creates can exceed cap (intentional per comment). UTC date math deliberate.
-
-## src/services/planCategory.service.ts
-
-- [LOW] slugifyCategory strips a literal combining-marks range (file-byte fragile); uniqueKey unbounded collision loop + race; sort_order=max+1 outside tx (dup possible). Soft-delete-aware checks correct.
-
-## src/services/projects.service.ts
-
-- [LOW] updateProject renames NAS folder after DB commit outside any tx (DB/NAS divergence, failure unlogged at call site, 143); getProject does a synchronous full-base readdirSync on every GET (95); deleteProject removes folder BEFORE the DB delete (218) — inconsistent with orders.service DB-first ordering; Record<string,any> typing.
-
-## src/services/users.service.ts
-
-- [MEDIUM] createUser username/email uniqueness via separate findFirst BEFORE a non-transactional create (116-142) — TOCTOU; duplicate -> unhandled 500 not 409 (updateUser already fixed this in a tx).
-- [LOW] createUser no in-service min password length (updateUser requires >=8); where: any. Last-admin + self-delete guards correct.
-
-## src/services/warehouse.service.ts
-
-- [HIGH] cancelReservation (959-988) has NO row lock and NO transaction — a concurrent confirmIssue fulfilling the same reservation interleaves -> lost fulfillment, double-counted stock. Every other warehouse op locks the parent row; this one was missed.
-- [MEDIUM] selectFifoBatches orders only by received_at no id tie-break (170) + second-truncated precision -> nondeterministic FIFO; getBelowMinimumItems N+1 (232-261).
-- [LOW] validateIssueReservationRules N+1; confirmInventorySession negative-diff decrements item_locations independent of consumed batches (drift); surplus enters at unit_price:0 (valuation); dead itemQty/linePrice locals. Lock/FIFO/storno guards otherwise correct.
-
-## src/schemas/common.ts
-
-- [HIGH] Contains only parseBody — NO shared coercion helpers despite the convention; the z.union number/string transform idiom is re-implemented ~150x across schemas with no shared home. Root cause of the NaN findings below.
-- [LOW] Deprecated ZodSchema import (1); Zod 4 prefers z.ZodType.
-
-## src/schemas/ai.schema.ts
-
-- [LOW] Message objects plain z.object (not strict); AiBudgetSchema.budget_usd no upper bound (39, but Number.isFinite-guarded).
-
-## src/schemas/attendance.schema.ts
-
-- [HIGH] Pervasive unguarded Number(v) transform with NO NaN check on user_id, year, vacation/sick totals, project_id, leave_hours, and all lat/lng/accuracy fields (13-145) — NaN flows to service/Prisma; project_id NaN -> bogus FK.
-- [MEDIUM] Time fields (arrival/departure/break) unbounded z.string() with no HH:MM regex (45-48 etc.).
-- [LOW] Plain z.object not strict; minutes not capped at 59.
-
-## src/schemas/auth.schema.ts
-
-- [MEDIUM] username/password and TOTP password fields have no .max() (4-5) — unbounded string to bcrypt (file caps backup codes for this exact DoS reason but not password).
-- [LOW] totp_code .length(6) but not digits-only; plain objects.
-
-## src/schemas/bank-accounts.schema.ts
-
-- [MEDIUM] iban/bic/account_number/currency/names all unbounded nullish strings (4-9) — no length caps, no IBAN/BIC/ISO format checks.
-- [LOW] position unguarded number-from-form (NaN); plain objects.
-
-## src/schemas/customers.schema.ts
-
-- [MEDIUM] custom_fields: z.array(z.any()) (11,23) — fully over-permissive, arbitrary nested payload persisted as-is.
-- [LOW] All address/id strings unbounded, no format checks; plain objects.
-
-## src/schemas/invoices.schema.ts
-
-- [LOW] quantity/unit_price throw on NaN (good) but vat_rate/position/order_id/customer_id use the UNGUARDED idiom; status/currency/language free strings (no enum); unbounded text; plain objects.
-
-## src/schemas/leave-requests.schema.ts
-
-- [LOW] date_from/date_to min(1) no YYYY-MM-DD regex, no date_to>=date_from cross-check; unbounded notes; plain objects.

-## src/schemas/offers.schema.ts
-
-- [LOW] Number coercions correctly refine(!isNaN) but re-implement the idiom ~7x; currency/language free strings; unbounded text; plain objects.
-

-
-- [LOW] Same as offers — refined but duplicated idiom; free currency/language; unbounded text; plain objects.
-
-## src/schemas/plan.schema.ts
-
-- [LOW] intFromForm (7-10) is a proper guarded helper but defined locally (belongs in common.ts); project_id coercions (21-102) use the UNGUARDED idiom not intFromForm -> NaN FK; plain objects.
-

+## .env.example
 
 - Clean
 
-## src/schemas/profile.schema.ts
-
-- [MEDIUM] new_password .min(8) no .max() (8); current_password unbounded — unbounded to bcrypt.
-- [LOW] first_name/last_name no min/max; plain objects.
-
-## src/schemas/projects.schema.ts
-
-- [LOW] Create FK fields refine-guard NaN, but Update + quotation_id/order_id use the UNGUARDED idiom (29-44) -> NaN FK on update; status free string (no enum); date strings no regex; plain objects.
-
-## src/schemas/received-invoices.schema.ts
-
-- [HIGH] month/year coerce via Number(v) with NO NaN guard AND no range bounds (5-6,53-60) — month not 1-12, year unbounded; flows into the ledger + date logic.
-- [MEDIUM] amount/vat_rate/vat_amount unguarded idiom (NaN); vat_rate no range bound (negative/>100 accepted) — load-bearing for gross VAT back-calc.
-- [LOW] Unbounded text; plain objects.
-
-## src/schemas/roles.schema.ts
-
-- [LOW] permission_ids: z.array(z.number()) not .int()/positive, no .max() length; name no slug/format; unbounded text; plain objects.
-
-## src/schemas/scope-templates.schema.ts
-
-- [LOW] position/id/default_price unguarded number-from-form (NaN); name/title nullish/optional with no .min(1) (nameless template passes); unbounded text; plain objects.
-
-## src/schemas/settings.schema.ts
-
-- [MEDIUM] Every numeric setting — incl. security-relevant max_login_attempts, lockout_minutes, max_requests_per_minute (15-62) — uses the unguarded idiom with NO NaN guard and NO range bounds; NaN/0/negative can disable lockout/rate-limit.
-- [MEDIUM] custom_fields/supplier_field_order: z.array(z.any()); available_vat_rates no int/range; available_currencies no enum.
-- [LOW] Email-ish fields no .email(); plain objects.
-
-## src/schemas/trips.schema.ts
-
-- [HIGH] start_km/end_km/vehicle_id/user_id use the unguarded idiom — NO NaN check; confirmed routes/admin/trips.ts:226 end_km<start_km guard is bypassed when either is NaN (NaN compare = false) and Number() then writes NaN to Prisma. Real data-integrity bug.
-- [LOW] route_from/route_to unbounded; trip_date no regex; plain objects.
-
-## src/schemas/users.schema.ts
-
-- [MEDIUM] password .min(8) no .max() (6,22-25) — unbounded to bcrypt.
-- [LOW] role_id unguarded NaN; username/names no .max(); plain objects.
-
-## src/schemas/vehicles.schema.ts
-
-- [LOW] initial_km/actual_km unguarded NaN + no .min(0) (negative odometer); spz/name no .max()/plate regex; plain objects.
-
-## src/schemas/warehouse.schema.ts
-
-- [HIGH] All movement quantities/prices (ReceiptItem/IssueItem/InventoryItem/Reservation, 124-219) use the unguarded idiom — NO NaN guard, NO .min/positivity; confirmed these feed stock math in warehouse.service -> NaN/negative corrupt inventory totals.
-- [MEDIUM] All FK coercions (item_id/category_id/supplier_id/project_id/location_id/batch_id/reservation_id) unguarded -> NaN FK to Prisma lookups.
-- [LOW] Supplier email/phone no format check; date strings no regex; unbounded text; plain objects; idiom duplicated dozens of times.
-
-## src/utils/czech-holidays.ts
-
-- [LOW] Easter calc parses YYYY-MM-DD as UTC midnight then reads with local getters (50-57) — correct only because Prague is east of UTC; a negative-offset TZ would be a day early (safe today, fragile). Minor formatting duplication. holidayCache bounded by year.
-
-## src/utils/date.ts
+## .gitignore
 
 - Clean
 
-## src/utils/encryption.ts
-
-- [MEDIUM] Format detection via split(":").length===3 (27-28) — brittle (a malformed TS value falls through to base64 branch). Crypto sound: random IV per encrypt (no reuse), GCM tag verified, raw 32-byte key. A version/prefix tag would be more robust.
-
-## src/utils/html-to-pdf.ts
-
-- [MEDIUM] process.env.CHROMIUM_PATH || "/usr/bin/chromium-browser" || "/usr/bin/chromium" (21-24) — third path is dead (second operand always truthy); if only chromium exists, launch fails. Browser lifecycle/finally sound (no leak). Injection safety handled upstream.
-
-## src/utils/pagination.ts
-
-- [LOW] sort/search passed through unvalidated (19,22) — trust-boundary note for callers (orderBy field needs an allowlist); page/limit clamping correct.
-
-## src/utils/planAuditDescription.ts
+## .prettierignore
 
 - Clean
 
-## src/utils/totp.ts
-
-- [LOW] console.error logs raw error on decrypt/verify failure (27) — no secret leak; swallow-to-{valid:false} intentional. Correct RFC-6238 (window:1, params from config); replay protection in auth.ts.

-- [LOW] JwtPayload.role vs AuthData.roleName (51,60) — the documented footgun that invites authData.role==="admin"; no bug here but a hazard.
+- [LOW] (line 39) Stale doc: project-structure comment says "React 18 + Material UI frontend" while the tech-stack table (line 17) says React 19.2.7.
+- [LOW] (line 50) Inconsistent test counts: line 50 says the suite is "17 files" while the Testing section (line 250) says "18 files / 247 tests".
 
-## prisma/seed.ts
+## boneyard.config.json
 
-- [MEDIUM] main() unconditionally deleteManys ALL role_permissions + permissions (321-322) before re-inserting — prod-destructive if ever misused (custom roles lose all permissions; stale-reconciliation at 351-368 is dead after the wipe). Dev-only by policy.
-- [LOW] Seeds an admin/admin user hashing the literal "admin" (389) — dev convenience, risk if run on a reachable env.
+- Clean
 
-## scripts/migrate-received-invoices-to-nas.ts
+## eslint.config.mjs
 
-- [LOW] Treats saveReceivedInvoice as sync (41) — verify; sets file_data: null after a claimed-success save with no read-back verification (56) — a 0-byte/corrupt write would lose the only DB copy (one-shot migration).
+- [LOW] (line 54-61) eslint-plugin-react-refresh is imported and registered in the frontend block but no react-refresh rule is ever enabled — dead plugin registration (e.g. only-export-components is never turned on).
 
-## scripts/rotate-totp-key.ts
+## index.html
 
-- [HIGH] Hand-rolled decrypt (6-14) only handles the TS iv:enc:tag format; PHP-legacy base64 secrets (no colon) -> Buffer.from(undefined,'hex') throws inside $transaction with no per-user try/catch (58-65) -> the FIRST legacy secret aborts/rolls back the ENTIRE batch. Should reuse src/utils/encryption.ts dual-format decrypt.
-- [LOW] Dry-run shows [FAIL] rows for legacy secrets the real run cannot process — operator must not ignore them.
+- [LOW] (line 2-6) data-theme="dark" and theme-color #12121a are hardcoded with no inline pre-React script syncing the stored 'mui-mode' localStorage key, so light-mode users get a dark flash on every page load until React/ThemeContext mounts.
+
+## package.json
+
+- [LOW] (line 17) "db:push": "prisma db push" provides a first-class npm script for the command CLAUDE.md's golden rule forbids (NEVER use prisma db push — it causes migration drift); the script should be removed.
+- [LOW] (line 50) @types/jsdom is listed in production dependencies (installed on prod via npm install --omit=dev) — type packages belong in devDependencies.
+- [LOW] (line 88) concurrently is a devDependency but no npm script uses it (dev script is plain `tsx watch`) — unused dependency.
+
+## prisma.config.ts
+
+- Clean
 
 ## prisma/schema.prisma
 
-- [HIGH] Entire sklad\_\* (warehouse) module declares relations with NO explicit onDelete (780-958) — header->line deletes and master-data deletes get engine-default behavior, inconsistent with the explicit cascade/setNull/restrict used everywhere else; define explicit onDelete (Cascade line->header, Restrict line->master-data).
-- [MEDIUM] Warehouse document numbers receipt_number/issue_number/session_number (825,877,935) are nullable and NOT unique — unlike every other document-number column (invoice/order/quotation are @unique); two receipts can share a number.
-- [MEDIUM] invoices.order_id/customer_id, orders.quotation_id/customer_id, quotations.customer_id, project FKs have no explicit onDelete (default Restrict — likely intended but implicit). Several \*\_id are bare Int with no relation/FK -> orphan risk (received_invoices.uploaded_by, quotations.locked_by can point at deleted users).
-- [MEDIUM] sklad_issues.project_id/issued_by, sklad_receipts.supplier_id/received_by, bank_accounts declare no @@index (MySQL auto-indexes the FK constraint, but non-FK hot filters are uncovered and the schema is inconsistent vs the rest).
-- [LOW] Most modified_at/updated_at lack @updatedAt (rely on app code -> stale-timestamp footgun); duplicate identical audit_logs created_at indexes (71,73); is_deleted absent on financial/document models (audit_logs compensates); invoice/order/project/quotation status are free strings not Prisma enums; config lists stored as LongText JSON not Json columns. Money is correctly Decimal throughout (good).
+- [MEDIUM] (line 302-309) number_sequences has fully nullable type (String?), year (Int?) and last_number (Int?) on the concurrency-critical numbering table — the [type, year] unique index does not prevent duplicate rows when either column is NULL (MySQL allows multiple NULLs in unique indexes), and a nullable counter forces null-handling in the locking/sequence code; all three should be required.
+- [LOW] (line 26, 36) attendance.project_id is a bare Int? with only an index (idx_project_id) and no relation/FK to projects (unlike attendance_project_logs.project_id) — deleting a project leaves dangling references with no referential integrity.
+- [LOW] (line 545-560, 624-634) Auth token tables have no FK to users: refresh_tokens.user_id is @db.UnsignedInt (type-mismatched against signed users.id, which blocks adding one) and totp_login_tokens.user_id has no relation — orphaned token rows persist after user deletion; same FK-less pattern on ai_usage.user_id, ai_chat_messages.user_id, received_invoices.uploaded_by and quotations.locked_by.
+- [LOW] (line 30, 293, 650, 673, 1043) Most updated_at columns are DateTime? @default(now()) WITHOUT @updatedAt (and the generated DDL has no ON UPDATE CURRENT_TIMESTAMP), so they only change when service code remembers to set them manually — inconsistent with ai_conversations/plan_categories which do use @updatedAt; updates that forget leave stale timestamps.
 
-## src/admin/ui/Alert.tsx
+## prisma/seed.ts
 
-- [LOW] MUI close button gets default English aria-label "Close" amid otherwise-Czech UI (18). Clean otherwise.
+- [MEDIUM] (line 320-327) Seed deleteMany-wipes ALL permissions/role_permissions then re-inserts only the hardcoded PERMISSIONS list, which omits the migration-seeded 'ai.use' (20260608120000_add_ai_assistant) — re-seeding a migrated dev/test DB silently deletes the AI permission row and any non-admin grants, desyncing the DB from the migration baseline (Odin page is gated on hasPermission("ai.use")).
+- [LOW] (line 306-315) The destructive-wipe production guard keys solely off APP*ENV === "production"; a DATABASE_URL pointing at prod with APP_ENV unset/local (e.g. after a migrate-diff session against the prod URL) still wipes prod permissions — no DB-target check like the test setup's hard-throw on non-\_test* database names.
 
-## src/admin/ui/AppShell.tsx
+## scripts/check-roles.mjs
 
-- [MEDIUM] `setTimeout(()=>logout(),400)` (27) is fire-and-forget, never cleared — fires on an unmounted tree if unmounted within 400ms.
-- [LOW] Decorative inline SVGs lack aria-hidden. Otherwise clean.
+- [MEDIUM] (line 2) Bare `new PrismaClient()` throws PrismaClientInitializationError at construction under Prisma 7 (driver adapter is mandatory — verified by running the script), and the script never loads dotenv so DATABASE_URL would be undefined anyway; it crashes on every invocation and should import the shared adapter-wired client from src/config/database like seed.ts does.
 
-## src/admin/ui/Button.tsx
+## scripts/migrate-received-invoices-to-nas.ts
 
-- Clean (sound polymorphic `component` pattern, caller sx wins).
+- [MEDIUM] (line 9, 21-30, 41, 61, 87-90) Script is fully dead/broken against the current codebase: it imports a nonexistent `nasFinancialsManager` export (the module now exports nasInvoicesManager/nasOrdersManager after the NAS split), calls removed methods saveReceivedInvoice/readReceivedInvoice (now saveReceived/readReceived), and queries/updates received_invoices.file_data/file_path fields that exist in neither schema.prisma nor any migration; the NAS_FINANCIALS_PATH usage header is stale too. scripts/ is excluded from every tsconfig so typecheck never catches it, and nas-financials-manager.ts (line 19) still references this script as the canonical safe-migration mechanism.
+- [LOW] (line 69-73) Reaches into the manager's private basePath via `as unknown as { basePath: string }` cast and concatenates the path manually with "/" — a type-safety hole that bypasses the manager's own path resolution/guards.
 
-## src/admin/ui/Card.tsx
+## scripts/rotate-totp-key.ts
 
-- [MEDIUM] Always wraps children in CardContent with no opt-out/contentProps — edge-to-edge content (media/table) can't use this primitive. Otherwise clean.
+- [LOW] (line 37-52) The --dry-run path returns from main() without prisma.$disconnect() (only the non-dry-run path disconnects at line 67), so the open mariadb pool keeps the event loop alive and the script hangs after printing "Dry run complete."
+- [LOW] (line 19-25) Old/new AES-256 encryption keys are passed as plain command-line arguments — they end up in shell history and are visible in the process list (ps) for the duration of the run; reading from env vars or prompting would avoid the leak.
 
-## src/admin/ui/Checkbox.tsx
+## scripts/seed-test-users.mjs
 
-- [MEDIUM] No disabled/name/id/indeterminate/required passthrough — minimal API forces callers to raw MUI. Otherwise clean.
+- [MEDIUM] (line 10) Bare `new PrismaClient()` throws PrismaClientInitializationError at construction under Prisma 7 (driver adapter is mandatory — empirically verified for the identical pattern in check-roles.mjs), and the script never loads dotenv — it crashes on every invocation, so neither documented invocation in the header (node / npx tsx) works.
+- [LOW] (line 57-107) No production guard (unlike prisma/seed.ts's APP_ENV hard-throw): once the client construction is fixed, running it with a production DATABASE_URL would create 20 active accounts with the known shared password "test1234".
 
-## src/admin/ui/ConfirmDialog.tsx
-
-- [MEDIUM] `cancelText` (and `confirmVariant`) not frozen in `shown` while title/message/confirmText/loading are — cancel label can flicker during the close fade. message is plain string (no XSS). Otherwise clean.
-
-## src/admin/ui/DataTable.tsx
-
-- [MEDIUM] Mobile card branch (78-173) ignores sortBy/sortDir/onSort — sorting controls vanish on phones with no alternative.
-- [LOW] Desktop action cells do NOT stopPropagation (237,254-275) — an action button in an `onRowClick` row fires BOTH (potential double-action; HIGH if any table pairs them). `"actions"` column key magically special-cased (undocumented). Status tints correctly channel-alpha.
-
-## src/admin/ui/DateField.tsx
-
-- [LOW] Dual-label coexistence (picker label + outer Field); parseISO guarded by isValid. Clean.
-
-## src/admin/ui/EmptyState.tsx
-
-- [LOW] icon sized via fontSize:48 — assumes font/SVG-inheriting glyph (an <img> won't scale). Clean.
-
-## src/admin/ui/Field.tsx
-
-- [HIGH] `<Typography component="label">` (24) has NO `htmlFor` and injects no id into children — label not associated with the input (no click-to-focus, screen readers don't announce). System-wide since this is the shared form-label primitive.
-- [MEDIUM] error/hint not linked via aria-describedby and input gets no aria-invalid (41-49). SwitchField lacks disabled passthrough.
-
-## src/admin/ui/FileUpload.tsx
-
-- [LOW] Keys include array index; remove button uses entity glyph with proper aria-label. Clean.
-
-## src/admin/ui/FilterBar.tsx
-
-- Clean.
-
-## src/admin/ui/LoadingState.tsx
-
-- [LOW] CircularProgress has no accessible label when `label` omitted (the full-screen AppShell case). Clean otherwise.
-
-## src/admin/ui/Modal.tsx
-
-- [MEDIUM] `cancelText` not frozen in `shown` (cancel label flickers on close); DialogContent renders LIVE children (77) so the form body still flashes its cleared state during the fade — the exact issue the freeze targets, unsolved for the body. Otherwise clean.
-
-## src/admin/ui/MonthField.tsx
-
-- [LOW] ~90% duplicate of DateField.tsx (low-value to consolidate); parseISO guarded. Clean.
-
-## src/admin/ui/MuiProvider.tsx
-
-- [LOW] `defaultMode="dark"` hardcoded (11); verify it agrees with ThemeContext's `data-theme`/`mui-mode` source of truth to avoid a one-frame mismatch. Clean otherwise.

+- [LOW] (line 323-336) API key is blanked then restored on the line after the assertion — if the 503 expectation fails, the restore is skipped and the rest of the file runs with apiKey="" until afterAll; should use try/finally like the budget test at lines 119-129 does.

-- [LOW] TabPanel unmounts inactive content with no role="tabpanel"/aria-labelledby wiring (a11y-incomplete).
+- [LOW] (line 112-118) "Deleting a draft" tests (also 183-189 and 267-274) never push the draft id into the cleanup array and never assert the delete service result — if deleteIssuedOrder/deleteInvoice/deleteOffer returns an error the test still passes (preview unchanged either way) and the row leaks into the shared app_test DB.
 
-## src/admin/ui/TextField.tsx
+## src/**tests**/env.test.ts
 
-- Clean.
+- [LOW] (line 36-68) The "failure path" describe asserts locally re-declared copies of the validation predicates (HEX64_RE, portValid, expiryValid) rather than exercising src/config/env.ts — it can never catch a regression in the real validation and drifts silently if env.ts changes (the comment acknowledges this, but only the happy-path assertions touch real code).

-- [LOW] Non-matchPrefix branch uses bare `pathname.startsWith(item.path)` (no boundary) — fragile if a `/x-foo` route is ever added (items needing exactness set end:true). Verbose inline SVG set.
+- [LOW] (line 24-29) Vacuous-pass risk: expect(Number(b.number)).toBe(Number(a.number) + 1) — issued_order_number_pattern is settings-configurable, and for any non-numeric pattern both sides become NaN and vitest's toBe (Object.is) treats NaN===NaN as a pass; numbering.test.ts's assertStrictIncrement (which asserts the parsed suffixes are not NaN) exists precisely to avoid this.
+- [LOW] (line 191-211) Cleanup gap: the order created in 'deletes, cascades items, frees the latest number' is never pushed to createdIds (unlike every other test in the file), so if any assertion before deleteIssuedOrder throws (e.g. expect(before).toBeTruthy() at line 198), the row and its consumed number leak into app_test and survive afterEach.

-- [MEDIUM] Module-level lock state — production-safe (balanced [open] dep + cleanup), but a StrictMode/hot-reload double-invoke can transiently skew lockCount.
-- [LOW] Stale comment references removed base.css (now GlobalStyles.tsx).
+- [LOW] (line 157-183) Cleanup gap: in the deleteOrder regression test, orderId is never pushed to createdOrderIds and the auto-created project is never pushed to createdProjectIds (other tests push immediately after create), so a mid-test assertion failure before deleteOrder leaks both rows past afterEach into app_test.
 
-## src/admin/pages/Warehouse.tsx
+## src/**tests**/nas-document-manager.test.ts
 
-- [LOW] Dead/duplicated `MovementRow` type drift (75); redundant per-column `?? 0`; cosmetic isLoading gating. Clean otherwise (read-only).
+- Clean
 
-## src/admin/pages/WarehouseCategories.tsx
+## src/**tests**/nas-file-manager.test.ts
 
-- [MEDIUM] `sort_order` via `parseInt(...)||0` no radix (308) — drops a legit 0 and truncates "3.9"->3; convention wants Number/NaN-guard.
-- [LOW] Redundant `saving` state duplicates `submitMutation.isPending`. Broad ["warehouse"] invalidation correct.
+- [LOW] (line 7-57) The first describe instantiates new NasFileManager() bound to the real env-configured NAS_PATH, and its two 'rejects path traversal' tests (lines 31-34, 53-56) pass vacuously: project 'PRJ-001' never exists, so resolveProjectPath returns null via findProjectFolder not-found — yielding the same 'Neplatná cesta' message whether or not the traversal guard fired. Only the tmp-dir tests at lines 105-127 genuinely exercise the guard; the first-describe traversal cases are redundant false confidence and should use the constructor seam like the rest.
 
-## src/admin/pages/WarehouseInventory.tsx
+## src/**tests**/nas-project-folder.test.ts
 
-- [MEDIUM] `items` column renders `s.items?.length ?? 0` (125) but list endpoint omits items -> always shows 0; should use a \_count. Otherwise clean.
+- Clean
 
-## src/admin/pages/WarehouseInventoryDetail.tsx
+## src/**tests**/numbering.test.ts
 
-- [HIGH] Rules-of-Hooks: `return <Forbidden/>` (70) precedes `useApiMutation` (72) -> hook-count mismatch crash on permission change.
-- [LOW] `.../0/confirm` URL fallback is dead (handler guards null). Broad invalidation correct.
+- Clean
 
-## src/admin/pages/WarehouseInventoryForm.tsx
+## src/**tests**/offer-invoice-totals.test.ts
 
-- [HIGH] Rules-of-Hooks: `return <Forbidden/>` (83) precedes `useApiMutation` (94).
-- [MEDIUM] `actual_qty` via `Number(e.target.value)` no NaN guard (249) — clearing field -> NaN in payload (receipt/issue forms use parseDecimal). validate() doesn't check qty finite.
+- Clean
 
-## src/admin/pages/WarehouseIssueDetail.tsx
+## src/**tests**/order-totals.test.ts
 
-- [HIGH] Rules-of-Hooks: `return <Forbidden/>` (73) precedes useApiMutation (77,89).
-- [MEDIUM] Project link uses raw `<Typography component="a" href>` (316-330) not RouterLink -> full-page reload, breaks SPA nav.
-- [LOW] Dead `/0/` URL fallbacks.
+- [LOW] (line 22) Dead code: createdCustomerIds is declared and cleaned up in afterEach (lines 29-30) but never populated — verified createOrder/createIssuedOrder never create customer rows in these tests.
+- [LOW] (line 157) Month zero-padding via template literal `0${STATS_MONTH}` (also lines 185-186 with STATS_MONTH+1) only works for single-digit months — changing STATS_MONTH to 9+ silently produces an invalid date string like "2097-010-15" instead of failing loudly.
 
-## src/admin/pages/WarehouseIssueForm.tsx
+## src/**tests**/orders-list.test.ts
 
-- [HIGH] Rules-of-Hooks: `return <Forbidden/>` (267) precedes useApiMutation/useState (335,347).
-- [MEDIUM] `confirmIssue` setState(id) then immediately `await mutateAsync`; the url: closure reads pre-update id -> first confirm hits `/0/confirm`. Pass id as mutation variable.
-- [LOW] Form-seeding effects (238,242) are effect-as-derived-state.
+- Clean
 
-## src/admin/pages/WarehouseIssues.tsx
+## src/**tests**/plan.test.ts
 
-- Clean (kit, FilterBar, PageEnter, debounce, \_count.items, keys).
+- [LOW] (line 1161-1170) Silent `.catch(() => {})` on the noPerm user/role cleanup lacks the justifying comment the repo convention requires for intentionally-silent catches (the matching scope-user cleanup at lines 85-92 has one).
 
-## src/admin/pages/WarehouseItemDetail.tsx
+## src/**tests**/planAuditDescription.test.ts
 
-- [HIGH] Rules-of-Hooks: `return <Forbidden/>` (157) precedes useApiMutation (164,180).
-- [MEDIUM] Error-handling effect navigates away (148-153) — effect-as-control-flow (could be a render branch).
-- [LOW] Form-seed logic duplicated 3x (128/132/248-261); `useModalLock(editing)` (155) locks page scroll for an in-page (non-modal) edit form — likely unintended.
+- Clean
 
-## src/admin/pages/WarehouseItems.tsx
+## src/**tests**/planCategory.test.ts
 
-- Clean (kit, FilterBar, useTableSort, debounce, keys, rowInactive).
+- [LOW] (line 37) Only test file that calls prisma.$disconnect() on the shared client in afterAll — harmless today because vitest isolates each file in its own worker, but inconsistent with every other suite and would break sibling files if isolation were ever turned off.
 
-## src/admin/pages/WarehouseLocations.tsx
+## src/**tests**/received-invoices-vat.test.ts
 
-- [LOW] toggleMutation toasts in handler not onSuccess (inconsistent); dead czechPlural ternary. Guard correctly after hooks. Clean otherwise.
+- [LOW] (line 49) Duplicated assertion with a stale comment: line 48 says the exact-equality pin is "replacing the toBeCloseTo above", but the original toBeCloseTo assertion at line 9 was never removed.
 
-## src/admin/pages/WarehouseReceiptDetail.tsx
+## src/**tests**/schema-nan.test.ts
 
-- [HIGH] Rules-of-Hooks: `return <Forbidden/>` (97) precedes useApiMutation (101,113,126).
-- [LOW] Dead `/0/` URL fallbacks; attachment link safe (noopener). Broad invalidation correct.
+- Clean
 
-## src/admin/pages/WarehouseReceiptForm.tsx
+## src/**tests**/setup.ts
 
-- [HIGH] Rules-of-Hooks: `return <Forbidden/>` (203) precedes useApiMutation/useState (269,281).
-- [MEDIUM] Same stale-closure confirm bug as IssueForm (307-309) -> `/0/confirm` on first confirm.
-- [LOW] Uses imperative document.createElement input + hand-rolled dropzone instead of kit FileUpload (620-633).
+- Clean
 
-## src/admin/pages/WarehouseReceipts.tsx
+## src/**tests**/warehouse.test.ts
 
-- Clean (kit, FilterBar, debounce, \_count.items, keys).
+- [LOW] (line 91-105) Cleanup order bug: sklad_items.deleteMany runs before sklad_inventory_lines.deleteMany (same in afterAll, 209-223), but sklad_inventory_lines.item_id FK-references sklad_items with onDelete: Restrict — leftover inventory-line test data would make the whole suite crash in beforeAll; latent today only because this file never creates inventory lines.
+- [LOW] (line 110-118) Silently swallowed errors: .catch(() => {}) on users/roles/projects cleanup without the explanatory comment the repo's 'never silently swallow' convention requires (the afterAll equivalents at 229-238 do have one); a masked FK-constraint failure here leaves a stale wh*test*\* user that makes the next run fail on the unique-username create with a misleading P2002 instead of the real cause.
 
-## src/admin/pages/WarehouseReports.tsx
+## src/admin/AdminApp.tsx
 
-- [MEDIUM] Project-consumption & movement-log tabs fetch via raw apiFetch + useState (263-290,386-413) not React Query — results NOT in ["warehouse"] cache, won't refresh on mutations; existing query options unused.
-- [LOW] Duplicated MovementLogRow type (46); empty `catch {}` -> setData([]) swallows fetch errors (285,408); raw `row.date` not formatDate'd (426).
+- Clean
 
-## src/admin/pages/WarehouseReservations.tsx
+## src/admin/GlobalStyles.tsx
 
-- [MEDIUM] Create & cancel use raw apiFetch + manual invalidate (170-217) not useApiMutation (broad key correct, but plumbing duplicated).
-- [LOW] Empty catches don't log; `quantity` via Number() no NaN guard (457) and `NaN<=0` is false so NaN can be submitted.
-
-## src/admin/pages/WarehouseSuppliers.tsx
-
-- [MEDIUM] `toggleActive` setState(id) then immediate `await mutateAsync` — url: closure reads null id -> PUT hits the collection root (wrong endpoint) on first toggle. Pass id as mutation variable.
-- [LOW] Redundant `saving` state. Guard correctly after hooks. Clean otherwise.
-
-## src/admin/pages/Attendance.tsx
-
-- [MEDIUM] `calculateBusinessDays` parses YYYY-MM-DD via `new Date()` (UTC midnight) + local `getDay()` (480-488) — can mis-count business days in the evening Prague window.
-- [LOW] leaveRequestMutation invalidates attendance/leave-requests/users but NOT ["leave"] (303) — approver's pending queue (["leave","pending"]) won't auto-refresh; live clock (676) never ticks; notes synced via effect can clobber unsaved edits (336-340). todayLocalStr used (good).
-
-## src/admin/pages/AttendanceAdmin.tsx
-
-- Clean (thin presenter over useAttendanceAdmin).
-
-## src/admin/pages/AttendanceBalances.tsx
-
-- [HIGH] Rules-of-Hooks: `return <Forbidden/>` (171) precedes useApiMutation (173,189).
-- [LOW] parseFloat on vacation/sick fields -> NaN on empty (770,781,794) into payload.
-
-## src/admin/pages/AttendanceCreate.tsx
-
-- [LOW] `leave_hours: parseFloat()` -> NaN on cleared field (190). todayLocalStr used; broad invalidation. Clean otherwise.
-
-## src/admin/pages/AttendanceHistory.tsx
-
-- [MEDIUM] ~865-line file with inline print-HTML template + hidden print JSX — split candidate.
-- [LOW] Duplicates holiday/business-day logic that also exists in attendanceHelpers (84-149). normalizeDateStr used; hooks before guard. Clean otherwise.
-
-## src/admin/pages/AttendanceLocation.tsx
-
-- [LOW] Dead LoadingState branch (199 unreachable, `!record` returns null at 187 while pending). Popup via createElement/textContent (no XSS); Leaflet cleanup correct. Clean.
-
-## src/admin/pages/AuditLog.tsx
-
-- [HIGH] Rules-of-Hooks: `return <Forbidden/>` (185-187) precedes useApiMutation (189).
-- keepPreviousData, FilterBar, broad invalidation, shared ENTITY_TYPE_LABELS. Otherwise clean.
-
-## src/admin/pages/CompanySettings.tsx
-
-- [MEDIUM] ~1503-line file — split candidate (info/banking/numbering/currency-VAT/logo cards).
-- [MEDIUM] Uses deprecated MUI `inputProps` (1312) — silently ignored in v7 so min/step not applied (rest of file uses slotProps.htmlInput).
-- [LOW] Doesn't wrap in PageEnter (raw motion.div per card — intentional embedded mode); fieldOrder index logic fragile. Blob cleanup correct.
-
-## src/admin/pages/Dashboard.tsx
-
-- [LOW] DashData hand-rolled with `[key]:unknown` index sig + `as DashData` cast (76,88) bypasses query typing; 2FA handlers use raw apiFetch + manual invalidate (179-211) not useApiMutation. getCzechDate used (good); gated sections. Clean otherwise.
-
-## src/admin/pages/InvoiceDetail.tsx
-
-- [MEDIUM] ~2243-line file — split candidate (SortableInvoiceRow / paid read-only view / create-edit form).
-- [MEDIUM] UTC anti-pattern `new Date(...).toISOString().split("T")[0]` for due_date default (494), issue/due/tax dates (645-651) and computedDueDate (818-823) — the latter reaches the saved payload (977), persisting a day-early due date in evening Prague.
-- [LOW] Editable `notes` state never wired to an input in non-paid mode (only form.notes saved) — confirm intended. DOMPurify correctly applied before the one dangerouslySetInnerHTML (1562) — no XSS. Money math guarded; blob cleanup correct.
-
-## src/admin/pages/Invoices.tsx
-
-- [LOW] handleDelete/toggleStatus/handlePdf use raw apiFetch + manual invalidate (broad keys, correct behavior, off-convention); overdue rowSx UTC-vs-local compare off by a day near midnight (506-507, visual only). Clean otherwise.
-
-## src/admin/pages/LeaveApproval.tsx
-
-- [HIGH] Rules-of-Hooks: `return <Forbidden/>` (158) precedes useApiMutation (160,173).
-- Broad invalidation on leave-requests/leave/attendance/users; reject requires note. Otherwise clean.
-
-## src/admin/pages/LeaveRequests.tsx
-
-- Clean — all hooks (useApiMutation:84) precede the guard (97); broad invalidation; truncation via title attr.
-
-## src/admin/pages/Login.tsx
-
-- [LOW] `verify2FA(loginToken!, ...)` non-null assertion (105) — a null token (server returns requires2FA w/o token) would pass `null!`. Otherwise secure: tokens via useAuth, no persisted token state, TOTP input strips non-digits, autoComplete=one-time-code, renders outside AppShell.
-
-## src/admin/pages/NotFound.tsx
-
-- Clean.
-
-## src/admin/pages/Odin.tsx
-
-- Clean (permission gate + OdinChat; PageEnter wrap).
-
-## src/admin/pages/OfferDetail.tsx
-
-- [HIGH] Heartbeat effect (730) deps omit `isCompleted` though the guard reads it (731) — lock heartbeat keeps running after transition to dokoncena (stale closure).
-- [MEDIUM] ~2059-line file — split candidate (SortableItemRow / scope-sections / draft logic).
-- [LOW] `payload: any` (884) and item-update casts; parseInt/parseFloat on qty/price yield NaN on cleared field (rendered until totals guard). Broad invalidation correct; draft parse guarded; blob revoked.
-
-## src/admin/pages/Offers.tsx
-
-- [LOW] Expired check uses idiosyncratic `new Date(new Date().toDateString())` (658, functional). Otherwise clean (broad keys, kit, blob revoke, keys).
-
-## src/admin/pages/OffersCustomers.tsx
-
-- [LOW] parseInt without radix on `key.split("_")[1]` (239,259,675, harmless decimal). Otherwise clean (custom-field re-key correct, broad invalidation, a11y).
-
-## src/admin/pages/OffersTemplates.tsx
-
-- [LOW] openEdit fetches via raw apiFetch (bypasses RQ cache) for on-demand modal. Guard is before a hooks-free body (no violation). Otherwise clean.
-
-## src/admin/pages/OrderDetail.tsx
-
-- [CRITICAL] Rules-of-Hooks: 3 useApiMutation (181,187,193) AFTER `return <Forbidden/>` (179) — crash when orders.view absent / permission flips.
-- [LOW] `valid_transitions?.filter(...).length! > 0` (466) misleading non-null assertion. Section rich text DOMPurify-sanitized before dangerouslySetInnerHTML (760) — no XSS. Broad invalidation; blob cleanup.
-
-## src/admin/pages/Orders.tsx
-
-- [LOW] vat_rate sent as raw string in JSON create (272, relies on Zod coercion). Otherwise clean — Forbidden return (312) after all hooks; broad invalidation; keys.
-
-## src/admin/pages/PlanWork.tsx
-
-- [LOW] Several mutation callbacks use `body: any`/`data: any` (185,395,412,476,491). `isoDate` toISOString().slice(0,10) is correct (Plan UTC convention, not a finding). Forbidden return after hooks; pulse timer cleaned; todayIsoLocal used. Clean otherwise.
-
-## src/admin/pages/ProjectDetail.tsx
-
-- [CRITICAL] Rules-of-Hooks: 4 useApiMutation (179,194,203,209) AFTER `return <Forbidden/>` (177).
-- [LOW] formatNoteDate duplicates utils/formatters date logic. Broad invalidation (projects/warehouse); keys.
-
-## src/admin/pages/Projects.tsx
-
-- [LOW] List query uses raw `search` not debounced (219) — every keystroke refetches (Offers/Orders debounce). Hooks (useApiMutation 124,173) precede the guard (222) — correct ordering. Broad invalidation; keys.
-
-## src/admin/pages/ReceivedInvoices.tsx
-
-- [MEDIUM] `toDateInput` uses `toISOString().split("T")[0]` (453) to seed edit-form dates — forbidden UTC-split (day-early evening Prague). Use normalizeDateStr.
-- [MEDIUM] ~1237-line file — split candidate (upload modal + edit modal).
-- [LOW] Render-phase ref mutation `hasLoadedOnce.current=true` (279); loose parseFloat typing (557). VAT-from-gross preserved; broad invalidation; blob cleanup.
-
-## src/admin/pages/Settings.tsx
-
-- [HIGH] Rules-of-Hooks: 5 useApiMutation (319,339,354,372,390) AFTER `return <Navigate/>` (315) — useQuery/useMemo/useState are above, mutations are not.
-- [MEDIUM] ~1354-line file — split candidate (roles / system-settings / system-info).
-- [LOW] `systemInfo as Record<string,any>` (679); O(n^2 log n) permission-group sort (1243, negligible). Tab state derived from URL (good); broad invalidation.
-
-## src/admin/pages/Trips.tsx
-
-- [HIGH] Rules-of-Hooks: 2 useApiMutation (190,204) AFTER `return <Forbidden/>` (188).
-- [LOW] Dead `[,setLastKm]` state (186, only setter used); parseInt without radix (287,315-316). todayLocalStr used; broad invalidation (trips/vehicles); keys.
-
-## src/admin/pages/TripsAdmin.tsx
-
-- [HIGH] Rules-of-Hooks: 2 useApiMutation (236,255) AFTER `return <Forbidden/>` (231).
-- [LOW] handlePrint uses raw printWindow.document.write of app data (344-417) — low XSS surface (React-escaped innerHTML) but fragile; iframe/template safer. Broad invalidation; keys.
-
-## src/admin/pages/TripsHistory.tsx
-
-- [LOW] `totals` computed before the Forbidden return (wasteful when unauthorized) — but all hooks precede the return (no violation). Read-only; kit; keys. Clean.
-
-## src/admin/pages/UiKit.tsx
-
-- Clean (dev-only showcase).
-
-## src/admin/pages/Users.tsx
-
-- [HIGH] Rules-of-Hooks: 3 useApiMutation (126,152,162) AFTER `return <Forbidden/>` (173).
-- [LOW] `roles[0]?.id ? ... : ""` default would skip a role id of 0 (never 0 in practice). Shared broad USER_INVALIDATE array (good); self-deactivation guarded; keys.
-
-## src/admin/pages/Vehicles.tsx
-
-- [HIGH] Rules-of-Hooks: 3 useApiMutation (121,136,146) AFTER `return <Forbidden/>` (162).
-- [LOW] Raw MUI `<Chip>` instead of kit StatusChip (264); `select: data as unknown as Vehicle[]` double-cast (100); parseInt without radix (404). Broad invalidation (vehicles/trips); rowInactive; keys.
+- Clean
 
 ## src/admin/components/AlertContainer.tsx
 
-- [LOW] Stacking offset keyed off array index (15) — removing a middle alert reflows/can overlap with 3+ alerts. Keys use alert.id. Otherwise clean.
+- Clean
 
 ## src/admin/components/AttendanceShiftTable.tsx
 
-- [LOW] Project-cell key falls back to index when log.id nullish (119); duration math not memoized. Otherwise clean (no any, keys, no effects).
+- Clean
 
 ## src/admin/components/BulkAttendanceModal.tsx
 
-- [LOW] Select-all label shows "Odznacit vse" when users empty (BulkPlanModal guards this — inconsistent). Otherwise clean.
+- Clean
 
 ## src/admin/components/BulkPlanModal.tsx
 
-- Clean (kit, derived activeCategories, keys, select-all guarded, no any).
+- Clean
 
 ## src/admin/components/ErrorBoundary.tsx
 
-- [LOW] componentDidCatch only console.errors (22) — no telemetry hook. Correct boundary pattern otherwise.
+- Clean
 
 ## src/admin/components/Forbidden.tsx
 
-- Clean.
+- Clean
 
 ## src/admin/components/OrderConfirmationModal.tsx
 
-- [MEDIUM] Local state (step/items/applyVat/lang) never reset on reopen — component is permanently mounted, toggled by isOpen; reopening shows prior step/edits and items captured once via useState(initialItems) go stale.
-- [MEDIUM] `finally` closes the modal even when onGenerate throws (58-77) — a generation error drops edited items with only a transient toast.
-- [LOW] Editable rows key={i} — deleting a non-last row shifts indices (focus jumps; data stays correct since controlled).
+- Clean
 
 ## src/admin/components/PlanCategoriesModal.tsx
 
-- [LOW] Label TextField uncontrolled defaultValue with no key={c.label} (148) — won't re-seed on external rename (color input does add key); inline delete-confirm instead of kit ConfirmDialog. Broad ["plan","dashboard","audit-log"] invalidation correct; onBlur-commit.
+- [LOW] (line 147-158) Rename TextField is uncontrolled and keyed on c.label, so when the PATCH fails (onError only alerts) the input keeps showing the user's unsaved text with no remount/reset — the row silently displays a value that differs from the server's label.
 
 ## src/admin/components/PlanCellModal.tsx
 
-- [MEDIUM] Props onSaveEntry/onUpdateEntry/onSaveOverride/onUpdateOverride typed `any` (77-82) — untyped save payloads on the most bug-prone path.
-- [LOW] EditForm derives state from `initial` via useState (201-206) relying on parent remount per record (no key reset — fragile if parent swaps entryId same-kind); odd Czech phrasing (415). Discriminated-union mode + kit otherwise strong.
+- [MEDIUM] (line 276-333) handleSubmit/handleDelete are try/finally with no catch: PlanWork's handlers (PlanWork.tsx:394-584) alert then rethrow, and Modal.tsx:93 / ConfirmDialog.tsx:88 invoke onSubmit/onConfirm as bare onClick handlers, so every failed save/delete surfaces as an unhandled promise rejection.
+- [MEDIUM] (line 476-479) DayInRangeModal's 'Vytvořit přepsání' async onClick has no submitting/disabled state — a double-click fires onCreateOverrideFromRange twice and the server is additive up to 3 records per day (plan.service.ts:690-713, no unique constraint on user_id+shift_date), creating duplicate identical overrides; its rejection is also unhandled (parent rethrows after alerting).
 
 ## src/admin/components/PlanGrid.tsx
 
-- [LOW] `projects.find(...)` inside per-cell render loop (612-616) O(days*users*cells\*projects) — build a useMemo Map (rarely hit since server embeds label); eachDay/days recomputed every render (not memoized). todayIso uses local Y/M/D (correct); thorough aria-labels.
+- [LOW] (line 427-433) todayIso() is a third hand-rolled copy of the canonical local-today helper (todayLocalStr in src/admin/utils/formatters.ts; PlanWork.tsx:103 has another, todayIsoLocal) — implementation is correct (local components, not toISOString slicing), but 'today' should have a single source per the conventions.
+- [LOW] (line 486-493, 583) The pulse 'nonce' re-trigger mechanism doesn't work as the comments claim: for back-to-back mutations on the same cell the button's className is unchanged and no CSS selector references the root's data-pulse attribute, so changing it cannot restart the descendant keyframe animation — repeat pulses on the same cell never re-animate.
 
 ## src/admin/components/PlanRangeChips.tsx
 
-- [LOW] `readonly` prop accepted then discarded via `void readonly` (17) — dead prop (PlanGrid still passes it). className styling intentional (classes defined in PlanGrid root). Otherwise clean.
+- Clean
 
 ## src/admin/components/ProjectFileManager.tsx
 
-- [MEDIUM] Drag-over has no drag-depth counter — handleDragLeave (377-380) fires on every child boundary -> drop overlay flickers during drag.
-- [MEDIUM] File ops use raw apiFetch + manual invalidate of sub-key `["projects",id,"files"]` (349-351) not broad ["projects"] (deliberate scope, documented deviation).
-- [LOW] `catch {}` substitutes a generic toast but never logs the real error (336,408,438,471,508); sequential per-file upload; breadcrumb join breaks if a folder name contains "/". Escape/Enter handling + canManage gating correct.
+- [MEDIUM] (line 355-357) All four mutations (upload, create-folder, delete, rename at 355-357, 419-421, 484-486, 522-524) invalidate only the targeted ["projects", id, "files"] key instead of the broad ["projects"] domain mandated by the convention; the project detail query ["projects", id] is never invalidated, so has_nas_folder (the hasNasFolder prop driving the empty-state text) stays stale after the first upload auto-creates the NAS folder.
+- [LOW] (line 50-135) File-type icon colors are hardcoded hex (#e6a817, #e74c3c, #3498db, rgba(230,168,23,0.15), ...) instead of theme tokens; only the fallback at 138 correctly uses var(--mui-palette-text-secondary) — violates the theme.vars color convention.
+- [LOW] (line 594-614) Rename has no in-flight guard: pressing Enter starts the async handleRename while renamingItem stays set, so a subsequent blur (or second Enter) fires handleRename again against the already-renamed path, producing a spurious 'Nepodařilo se přejmenovat' error alert after a successful rename.
 
 ## src/admin/components/RichEditor.tsx
 
-- [LOW] `_delta: any` on the Quill onChange param (91, react-quill-new loose types — could be unknown); useLayoutEffect font-set no-ops if ref not ready (mounts sync in practice). Never injects HTML — consumers DOMPurify-sanitize. No XSS.
+- [MEDIUM] (line 78, 93-97) lastValueRef is initialized once from the initial value prop and only updated on user edits; external prop changes (form reset / switching records arrive as source 'api' and are ignored), so a later user change whose content exactly equals the stale ref (e.g. re-pasting the same text after a reset) is silently dropped — onChange never fires and parent state desyncs from what the editor displays, losing the content on save.
 
 ## src/admin/components/ShiftFormModal.tsx
 
-- [MEDIUM] `leave_hours` via parseFloat (330-331) writes NaN to form state on empty input — serializes to invalid; should fall back to 0 like the Number(...)||0 pattern.
-- [LOW] Module-level mutable `_logKeyCounter` (20) shared across instances (fragile under StrictMode/concurrent instances) — use a per-instance ref/randomUUID; server-loaded logs may lack \_key -> index-key risk. Derived isWorkType/isCreate + kit otherwise correct.
+- Clean
 
 ## src/admin/components/ShortcutsHelp.tsx
 
-- [LOW] Entire component is `return null` — dead stub; remove the file + references, or wire it up.
+- Clean
 
 ## src/admin/components/dashboard/DashActivityFeed.tsx
 
-- Clean (escaped React children, single-source ENTITY_TYPE_LABELS).
+- Clean
 
 ## src/admin/components/dashboard/DashAttendanceToday.tsx
 
-- [LOW] Key `${u.user_id}-${i}` index-suffixed (75); user_id alone is unique. Clean.
+- Clean
 
 ## src/admin/components/dashboard/DashKpiCards.tsx
 
-- [LOW] buildKpiCards recomputed every render (124, cheap); framer-motion entrance has no reduced-motion branch (JS-driven animate not stopped by the GlobalStyles CSS reset) — applies to DashQuickActions/DashProfile/DashSessions too. Clean otherwise.
+- Clean
 
 ## src/admin/components/dashboard/DashProfile.tsx

+- [HIGH] (line 556) The QR <img> from api.qrserver.com is blocked by the production CSP (src/middleware/security.ts:30 img-src only allows 'self' data: blob: and \*.tile.openstreetmap.org), so every production 2FA enrollment shows a broken image and users must fall back to typing the secret manually. _(verified)_
+- [MEDIUM] (line 556) 2FA setup sends the full otpauth:// URI — including the plaintext TOTP secret and the account label — as a GET query param to the third-party service api.qrserver.com; the live 2FA secret leaves the system (and lands in that service's logs). Generate the QR locally (client-side QR lib) instead. _(severity adjusted by verification: The code at DashProfile.tsx:556 really does embed the full otpauth:// URI (secret included, from totp.ts:50) in an api.qrserver.com GET URL, but in production the global CSP (security.ts:30, img-src 'self' data: blob: https://\*.tile.openstreetmap.org, applied via server.ts:99 to the served index.html) blocks the request entirely — the secret never egresses in prod; instead the QR renders broken and users fall back to the manual-key entry (DashProfile.tsx:568). The flaw is real (secret leaks in non-CSP local/dev runs, and prod QR enrollment is silently broken) and should be fixed with a local QR render (the `qrcode` dep already exists), but the headline "live secret leaves the system" does not hold in production, so HIGH is overstated — MEDIUM gap/risk.)_
 
 ## src/admin/components/dashboard/DashQuickActions.tsx
 
-- [HIGH] handleTripSubmit (157-176) POSTs a trip via raw apiFetch and NEVER invalidates ["trips"]/["dashboard"] (no useQueryClient imported) — list/dashboard stay stale until manual refetch.

+- [MEDIUM] (line 105-139) openTripModal (109-115) and handleTripVehicleChange (130-135) silently ignore success:false API responses — no log, no alert, and the vehicle list/start-km just stays empty or stale, violating the never-silently-swallow rule (only the network-error catch logs).
+- [LOW] (line 121-139) Stale-response race: rapidly switching vehicles fires concurrent /trips/last-km/:id fetches with no cancellation or selected-id check, so a late response for the previous vehicle can overwrite start_km for the currently selected one.
 
 ## src/admin/components/dashboard/DashSessions.tsx
 
-- [LOW] Correctly invalidates ["sessions"]; shared `deleting` flag (one dialog at a time); no reduced-motion branch. Clean.
+- [MEDIUM] (line 101, 122) Both delete handlers use a bare `catch { alert.error(...) }` that discards the error object without logging it (console.error), violating the repo's "every catch logs" convention — the generic 'Chyba připojení' toast loses all diagnostics.

 ## src/admin/components/odin/OdinChat.tsx
 
-- [LOW] saveInvoice invalidates ["invoices"] (353) — broad key DOES cover received invoices (keyed ["invoices","received"]), so correct; persist() is fire-and-forget (failure only console.error, user not told history unsaved). Seed/auto-scroll effects are legitimate. Invoice-only guard correct.
+- [MEDIUM] (line 254-282) Extraction response handling silently drops per-file `error` entries (filtered out at 261-279 with no per-file notice) and never reads the server's `truncated` flag (routes/admin/ai.ts:141, set when the budget halts the batch mid-way), so failed or unprocessed files vanish without feedback; an all-failed batch reads as the misleading 'V přílohách jsem nenašel žádnou fakturu'.
+- [MEDIUM] (line 185-200) ensureActive returns null on a non-ok POST /conversations response (193) without logging or alerting, and submit then skips persist() — the just-sent turn is silently never saved to history (silent error swallow).
+- [MEDIUM] (line 287, 315-318) If ensureActive's apiFetch throws (network) AFTER a successful, billed extraction, the catch rolls back the thread to prevTurns (losing the assistant summary), shows the wrong error 'Chyba čtení faktur', yet leaves the review cards and already-cleared attachments — inconsistent UI state for a non-extraction failure.
+- [MEDIUM] (line 337-339) saveInvoice coerces user-edited free-text with raw Number(): a Czech-format amount like "1 234,56" becomes NaN, which JSON.stringify serializes as null, and the server's non-nullable nonNegativeNumberFromForm (received-invoices.schema.ts:10) rejects it with a 400 — no client-side number validation or comma handling before submit.
+- [MEDIUM] (line 374-400) onRename/onDelete handle !res.ok but have no try/catch around apiFetch, and OdinSidebar invokes them un-awaited (OdinSidebar.tsx:53,61) — a network failure becomes an unhandled promise rejection with no user feedback and no log.

+- [MEDIUM] (line 132-140) Row onKeyDown doesn't check e.target, so Enter/Space on the focused kebab IconButton bubbles to the row, preventDefault() cancels the button's native click activation, and the row gets selected instead — rename/delete menu is unreachable by keyboard; the comment claiming the nested button 'handles its own keys' is wrong (stopPropagation is only on the click event, which never fires).

+- [HIGH] (line 263-272) Backup-code 2FA login is broken: verify2FA always POSTs to /login/totp with the code as totp*code plus an isBackup flag the server ignores — the route validates with TotpVerifySchema (exactly 6 digits), so the 8-char backup codes Login.tsx collects always fail with 400 'Kód musí mít 6 číslic'; the real endpoint POST /api/admin/totp/backup-verify (expects backup_code) is never called anywhere in the frontend, locking out any user who lost their authenticator. *(verified)\_
+- [LOW] (line 139-150) silentRefresh success sets user but never sets cachedUserRef (while the failure path nulls it at 148), so checkSession's degraded fallbacks (lines 176-177 and 195-196: return !!cachedUserRef.current) report false for a session established via cookie refresh — inconsistent cache maintenance.

-- [HIGH] Does data fetching with useEffect+useState+manual setLoading (818-922) against the "React Query for fetching" convention, AND also invalidateQueries(["attendance"]) after mutations — two sources of truth (its own fetchData cache vs the ["attendance"] domain).
-- [MEDIUM] fetchData useCallback closes over `alert` (captured first render) with eslint-disable + initialLoadDone ref; pervasive Record<string,any>/any in print/payroll helpers (350,380,597,1319); 300ms sleeps before success toasts as a sync crutch.

Remaining impact is a likely-wrong printed Přesčas/Včetně line (can even print −8h) in an uncommon worked-holiday edge case — a real gap, not a HIGH likely-in-practice bug.)_
+- [MEDIUM] (line 827-829) Empty catch ('/_ silent _/') silently swallows the projects-list load failure — violates the 'never swallow errors, every catch logs' convention; the project selector just stays empty with no log or user feedback.

+- [LOW] (line 818-922) Data fetching via useEffect + useState instead of React Query (convention: 'use React Query for fetching, not effects'); the hook invalidates ["attendance"] for other consumers but its own records live in local state, so external ["attendance"] invalidations never refresh this page.
+- [LOW] (line 350-353, 380-384, 1320) Print path is typed Record<string, any> / log: any despite AttendanceRecord/UserTotal types existing in the same file, and the userId parameter of buildUserSectionHtml is unused.

-- [MEDIUM] Optimistic rollback stashed via `(createEntry as any)._rolled = rolled` (264,332,369,403,454,481) — mutating the TanStack mutation object is non-idiomatic and NOT concurrency-safe (two in-flight mutations overwrite each other's \_rolled → wrong-snapshot rollback). Use onMutate context.
-- [MEDIUM] Heavy any on mutationFn/onSuccess (237,243,379,385,491); gridQuery.queryFn does r.json() with no res.ok check (92-94) — treats an error body as undefined data.
-- [LOW] isoDate UTC slice is correct for Plan, but anchor seeded from a LOCAL `new Date()` then read with getUTC\* (27-31,70,80-86) — verify the late-evening Prague window doesn't shift the week/month anchor. keepPreviousData + broad invalidation correct.
+- [LOW] (line 22-24, 113) Default anchor is new Date() (local now) pushed through isoDate() = toISOString().slice(0,10) UTC slicing — in the 00:00-02:00 Prague window the grid opens on the previous UTC day (previous week on Monday, previous month on the 1st); this is the banned toISOString 'today' derivation, distinct from the exempt plan-module UTC date math (PlanWork.tsx passes no initialDate, so this is the live path).
+- [LOW] (line 530) updateOverride optimistic patch uses vars.body.project_id ?? existing?.project_id, so explicitly clearing the project (project_id: null) is treated as 'unchanged' and the old project briefly stays in the cell until refetch — updateEntry (401-404) handles the undefined-vs-null distinction correctly.
+- [LOW] (line 138-148) gridQuery's queryFn duplicates apiCall's error-message extraction (44-54) verbatim instead of reusing it.
+- [LOW] (line 604-606) rollbackMutation is a retained no-op shim (dead code) kept only so PlanWork.tsx call sites compile — both ends should be cleaned up.

+- Clean
 
 ## src/admin/lib/queries/attendance.ts
 
-- [MEDIUM] attendanceLocationOptions (166-185) bypasses jsonQuery: reads `result.data.record||result.data` from untyped `response.json()` with NO response.ok/401 guard — a 500/non-JSON throws an opaque error instead of the adapter's normalized one.
-- [LOW] historyOptions hardcodes limit=1000 in the queryFn (not in the key). Keys unique per action/year; enabled:!!id correct.
+- [LOW] (line 173) Route-param `id` (user-controlled string from useParams) is interpolated unencoded into the query string (`?action=location&id=${id}`) instead of using URLSearchParams/encodeURIComponent like the file's other helpers — an id containing `&` injects extra query params or breaks the request.
 
 ## src/admin/lib/queries/auditLog.ts

 ## src/admin/lib/queries/invoices.ts

 ## src/admin/lib/queries/leave.ts
 
-- [LOW] Two key families for one entity: ["leave-requests","mine"/"all"] vs ["leave","pending"/"processed"] — mutations invalidate both domains (consistent) but it's avoidable duplication that's easy to under-invalidate later; rows typed Record<string,unknown> despite a LeaveRequest interface in-file.
+- [MEDIUM] (line 17-42) Leave entity split across two query-key domains — `["leave-requests", ...]` (line 19) vs `["leave", "pending"/"processed"]` (lines 28, 37) — so no single broad domain key exists; every mutation must invalidate both prefixes (all 4 current call sites do, but any future mutation invalidating only `["leave"]` silently leaves the requests list stale), violating the documented broad-domain-key convention.
 
 ## src/admin/lib/queries/mutations.ts
 
-- [LOW] invalidate() loops single top-level string keys (100-104) — can't express a multi-segment broad key (fine for current usage); onSuccess user override force-cast hides signature mismatch. ApiError.status/401 sentinel/broad-invalidation default correct.
+- [LOW] (line 47-52) On a non-JSON error response (e.g. proxy 502/504 HTML page) the thrown 'Invalid JSON response' Error carries no `.status`, losing the HTTP code the `ApiError` contract promises, so callers branching on `err.status` (e.g. 409 handling) get undefined.
 
 ## src/admin/lib/queries/offers.ts
 
-- [LOW] offerListOptions (90) omits the <T> on paginatedJsonQuery → rows are `unknown` (the only list option missing its generic); retry:false on detail justified/documented.
+- [LOW] (line 95) `paginatedJsonQuery` is called without a row type (the only list helper in these files that omits it), returning `PaginatedResult<unknown>`; the consuming page papers over it with a `usePaginatedQuery<Quotation>` cast in Offers.tsx — pass the row interface here like invoiceListOptions/issuedOrderListOptions do.
+- [LOW] (line 4-7) Duplicate `CurrencyAmount` interface — third identical copy (also in invoices.ts:4-7 and issued-orders.ts:73-76); consolidate into a shared module.
 
 ## src/admin/lib/queries/orders.ts

 ## src/admin/lib/queries/plan.ts

 ## src/admin/lib/queries/projects.ts
 
-- [LOW] projectFilesOptions treats HTTP 404 as empty result (97-99, reasonable but undocumented divergence from jsonQuery). Keys safe.
+- [LOW] (line 97-99) projectFilesOptions silently maps a 404 to a fabricated empty listing, so a missing project / unmounted NAS folder is indistinguishable from a genuinely empty folder (swallowed error with no signal to the user).
+- [LOW] (line 20) Type-safety hole: `responsible_user_id: string` but the server stores/returns a number|null (schemas/projects.schema.ts uses nullableIntIdFromForm); ProjectDetail only works by accident via MUI Select's String() comparison and Zod coercion — should be `number | null`.
 
 ## src/admin/lib/queries/settings.ts
 
-- Clean — distinct keys; 5-min staleTime; require2FAOptions canonical (dashboard duplicate removed).
+- [LOW] (line 66-88) Same settings entity is cached under two unrelated top-level domains (['company-settings'] vs ['settings','system-info']/['settings','2fa'] — require_2fa even lives in both), so every settings mutation must remember to invalidate both keys, contrary to the broad-domain invalidation convention (Settings.tsx:341 indeed has to list both).
 
 ## src/admin/lib/queries/trips.ts
 
-- [LOW] tripListOptions and tripHistoryOptions hit the SAME endpoint under two key families (redundant cache); tripVehiclesOptions duplicates vehicleListOptions (same /vehicles endpoint cached twice — both invalidated correctly, verified). Redundant footprint only.
+- [HIGH] (line 52-63) tripListOptions consumes the paginated /api/admin/trips endpoint via plain jsonQuery, discarding the pagination meta: Trips.tsx calls it with {} (server default limit 25) and TripsAdmin with perPage:100 (server hard cap), so both lists silently truncate rows with no way to render pagination controls. _(verified)_
+- [HIGH] (line 95-103) tripHistoryOptions sends no page/per*page, so the server returns only the default 25 rows and the dropped pagination meta hides it — TripsHistory.tsx (lines 105-128) computes monthly km/business totals from the truncated rows, silently understating totals for any month with >25 trips. *(verified)\_
 
 ## src/admin/lib/queries/users.ts
 
-- [LOW] userListOptions key ["users",{permission}] fans out cache per-permission (a ["users"] mutation invalidates all via prefix — fine). Clean otherwise.
+- [LOW] (line 24-28) userListOptions hardcodes limit=100 against the paginated /users endpoint and drops the pagination meta via jsonQuery, so user pickers would silently omit users past the first 100 (server maxLimit is 100, so no higher limit is possible).
 
 ## src/admin/lib/queries/vehicles.ts
 
-- [LOW] Returns Record<string,unknown>[] (untyped; consumers cast). Broad ["vehicles"] key invalidated correctly.
+- [LOW] (line 7) vehicleListOptions types rows as Record<string, unknown>[] — an effectively untyped result that forces consumers into `as` casts, unlike every other query module which defines a proper interface.
 
 ## src/admin/lib/queries/warehouse.ts
 
-- [LOW] Detail keys ["warehouse",entity,id] share prefix with list (no collision); locationListOptions defaults filters in two places that must stay in sync (251-253); undefined filter segments in stock-status/movement-log keys. Every mutation invalidates broad ["warehouse"] (verified).
+- [LOW] (line 247-258) warehouseLocationListOptions cache key isn't normalized: undefined, {}, and {active:'true'} all produce the same request but three distinct queryKeys (`filters ?? {active:'true'}` only normalizes the undefined case), causing duplicate cache entries/fetches.

-- [HIGH] Module-level rateCache/rateCacheTime never reset between tests (beforeEach resets only mockFetch) — the "throws when API fails and no cache" test passes only because it happens to run before the cache is populated; order-dependent/brittle.
-- [MEDIUM] Conversion tests share the uncleared cache — once "today" is cached, later mockFetch resolutions are ignored on hit, asserting stale rates (false confidence).
-- [LOW] No test for the amount!=1 path (CNB rates per 100 units, e.g. JPY/HUF) where rate/r.amount matters — the most money-bug-prone branch is untested.

-- [MEDIUM] Skip-taken preview tests assume a fresh counter, but real projects/quotations rows in the test DB may already hold the first number — second!==first can pass for the wrong reason / the create could collide on the unique column.
-- [LOW] "increments" asserts only num1!==num2 (not strictly +1 / year/format preserved); NO concurrency test for the SELECT...FOR UPDATE path the whole fileParallelism:false workaround exists to protect.
+- [MEDIUM] (line 360-380) Double-submit race in handlePunch: the 6s safety timeout calls submitPunch(action, {}), but a late getCurrentPosition success callback (the exact 'browser hangs' case the timeout exists for) clears the already-fired timer and submits the same punch a second time; the late error callback additionally reopens the GPS dialog for a third submit — no flag prevents re-submission after the safety timeout fires.
+- [MEDIUM] (line 345-349) Effect syncs server notes into local state on every statusQuery.data identity change, wiping an unsaved notes draft whenever the status payload changes — e.g. switching the active project (same card) invalidates ['attendance'], the refetched project_logs change the data reference, and the user's typed note resets to the last-saved server value.
+- [MEDIUM] (line 679) Convention violation: `${theme.palette.success.main}33` string-concatenated alpha instead of the mandated theme.vars channel token (rgba(${theme.vars.palette.success.mainChannel} / .2)); theme.palette resolves to the light-scheme value under cssVariables, so the dark scheme (success #22c55e) keeps a light-scheme #15803d glow while the adjacent dot (bgcolor 'success.main') adapts.
+- [LOW] (line 271-304) Mutation TOut generics claim { message?: string }, but useApiMutation returns the envelope's `data` field while the attendance routes put `message` at the envelope level (e.g. attendance.ts:391 success(reply,{id},status,message)) — `result?.message` is always undefined, so server messages are never shown and toasts always fall back to the hardcoded text.
+- [LOW] (line 810-815) Duplicated code: `projects.find(p => String(p.id) === String(activeProjectId))` is evaluated three times inline for the same value; hoist to a local const.

-- [LOW] Far-future created_at (2037) to dodge the 2038 ceiling (brittle); updateEntry doesn't test inactive/unknown category or date_from>date_to; assertNotPastDate "today" boundary (the bug-prone path) untested.
+- [HIGH] (line 407-442) Create/edit modal submits are broken: handleCreateSubmit/handleEditSubmit (useAttendanceAdmin) send combined 'YYYY-MM-DDTHH:MM:00' datetimes for arrival/departure/break, but since commit 519edce (2026-06-09) CreateAttendanceSchema/UpdateAttendanceSchema validate them with timeString (HH:MM only) — every create/edit containing a time is rejected 400 'Čas musí být ve formátu HH:MM' (and the service itself expects full datetimes via new Date(...), so the schema contradicts both client and service); additionally break*start/break_end are absent from CreateAttendanceSchema, so breaks are silently stripped on create. *(verified)\_
+- [LOW] (line 433) Edit-mode ShiftFormModal is wired to onShiftDateChange={handleCreateShiftDateChange}, which mutates the CREATE form's state; harmless only because ShiftFormModal never calls onShiftDateChange in edit mode (it uses updateField directly) — misleading dead wiring that corrupts the create form if edit mode ever starts calling it.
+- [LOW] (line 28-49) Local UserTotalData interface duplicates UserTotal from useAttendanceAdmin and is applied via an 'as' cast at line 235 — the two shapes can drift silently; import/export the hook's type instead.

+- [LOW] (line 452-453) boxShadow callback uses theme.palette.primary.main instead of theme.vars (repeated at 603-605) — with cssVariables mode this resolves the light-scheme primary (#c73030) even in dark mode (dark primary is #d63031), violating the documented theme.vars convention.
+
+## src/admin/pages/AttendanceCreate.tsx

+- [HIGH] (line 80-99) handleSubmit posts the raw form, whose shape the API does not accept: arrival*date/break_start_date/break_start_time/break_end*\*/departure*date are not in CreateAttendanceSchema (silently stripped — breaks and overnight dates never save), times are never combined with dates (unlike useAttendanceAdmin's combineDatetime), so a validated 'HH:MM' reaches createAttendance which does new Date('08:00') → Invalid Date → 500 on work records; and since commit 519edce the always-sent empty-string time fields (arrival_time: "") fail timeString validation, so EVERY submit from this page — including leave records — returns 400. *(verified)\_

+- [MEDIUM] (line 84-149) Local getEasterSunday/getCzechHolidays/getBusinessDaysInMonth duplicate the shared holiday util (holidaysInMonth / src/utils/czech-holidays) which this file also imports — the same computed block mixes both sources (line 245 local vs 247 shared), a two-sources-of-truth divergence risk that directly enables the fund bug above.
+- [LOW] (line 245-249) Monthly fund formula (businessDays + holidayCount) _ 8 counts holidays that fall on Sat/Sun as +8h fund (holidaysInMonth returns all holidays; getBusinessDaysInMonth already excludes weekday holidays), so in months with a weekend holiday (5.7.2026 = Sunday, 26.12.2026 = Saturday — verified) the page shows a fund 8h higher than the admin/print computation (rawBizDays _ 8 in useAttendanceAdmin), producing wrong 'Zbývá/Přesčas' numbers for the user. _(severity adjusted by verification: The mechanism is real but the claimed harm is not: at AttendanceHistory.tsx:249 a weekend holiday does add +8h to `fund`, but the SAME +8h flows into `fondUsed` via `calculateFreeHolidayHours` (attendanceHelpers.ts:341-343 credits 8h for EVERY unworked holiday, weekend included; line 269-271 adds it), so `delta = fondUsed - fund` is invariant and the displayed Zbývá/Přesčas (lines 634-638 use `delta` directly; `monthlyFund.remaining/overtime` are never rendered) are NOT wrong — for July 2026 a full-time user gets fund 192, fondUsed 192, "Fond splněn", exactly as the admin model (184/184/0) concludes. What remains is a cosmetic cross-page inconsistency: the "Fond: X/Y" label (line 574) shows both numbers 8h higher than the admin/print fund (`rawBizDays*8`, useAttendanceAdmin.ts:292/520) in the ~1-2 months/year with a weekend holiday (2026-07-05 Sun, 2026-12-26 Sat verified), with the progress bar unaffected since both sides inflate equally — a LOW display-consistency cleanup, not a HIGH wrong-balance bug.)_
+- [LOW] (line 204) queryClient from useQueryClient() is declared but never used — dead code (plus the unused import).
+- [LOW] (line 258-261) records as unknown as Parameters<typeof calculateFreeHolidayHours>[0] — double-cast type hole that bypasses checking between the page's AttendanceRecord shape and the helper's expected record shape.

 - Clean
 
-## src/__tests__/planCategory.test.ts
+## src/admin/pages/AuditLog.tsx
 
-- [MEDIUM] Dedupe test asserts \_2 but cleanup is keyed to in-memory ids (afterAll), so a mid-run crash leaves rows that make the next run assert \_3 and fail (slug-prefix cleanup would be safer).
-- [LOW] No duplicate-label-on-update negative test, no deactivate/reactivate test; slugify empty-result collision (slugify("\*\*\*")→"") untested.
+- [MEDIUM] (line 131-180) Query errors are never surfaced: queryFn throws on failure but the component has no isError handling (and queryClient.ts defines no global query error handler), so a 500/network failure renders the misleading EmptyState 'Žádné záznamy k zobrazení' (line 368) instead of an error — a silently swallowed error on a main read path.
+- [LOW] (line 210-214) The client auto-attaches the backend's literal DELETE_ALL_AUDIT confirmation token whenever days===0, reducing the server's extra-confirmation safeguard for wiping the entire audit log to a single dropdown selection + Smazat click.
 
-## src/__tests__/received-invoices-vat.test.ts
+## src/admin/pages/CompanySettings.tsx
 
-- [LOW] Solid value checks but no half-cent rounding edge, no negative/credit-note amount; rounding pinned via toBeCloseTo rather than the stored 2-dp value.
+- [MEDIUM] (line 488-494) Save payload filters empty rows out of custom_fields but builds supplier_field_order from the UNFILTERED list (getFullFieldOrder over customFields indices), so saved custom_N keys misalign with the saved array — after reload the order filter (idx < customFields.length, line 271-277) drops/mismaps custom fields and the PDF supplier-block order is corrupted whenever an empty custom-field row existed at save time.
+- [MEDIUM] (line 345-412) The populate effect resets the entire form/customFields/fieldOrder whenever settingsData changes; with refetchOnWindowFocus:true (queryClient.ts) and the logo-upload invalidation of ['company-settings'] (line 529), a refetch that returns changed data (first logo upload flips has_logo; concurrent edit by another admin) silently clobbers the user's unsaved in-progress edits.
+- [MEDIUM] (line 1369-1383) VAT-rates CSV parsing maps empty segments through Number(''.trim())===0 which passes the !isNaN filter, so typing a trailing comma in 'Dostupné sazby DPH' immediately injects a spurious 0% rate into the controlled value (the adjacent currencies field correctly filters empties with .filter(Boolean); this one doesn't).
+- [LOW] (line 302-328) URL.createObjectURL/URL.revokeObjectURL side effects live INSIDE the setLogoUrl/setLogoUrlDark updater functions; state updaters must be pure — under React StrictMode double-invocation this creates a second, leaked blob URL per fetch (and double-revokes the previous one).
+- [LOW] (line 883) In standalone (non-embedded) mode the bank-accounts management card renders via (canManageBanking || !embedded) even when the user lacks settings.banking, exposing add/edit/delete UI whose requests will only fail server-side — inconsistent with the embedded-mode gating and with the page's own canManageBanking flag (computed at 169 but effectively unused standalone).
 
-## src/__tests__/schema-nan.test.ts

-- [MEDIUM] Proves "not-a-number" is rejected but never that a valid numeric STRING ("2") is coerced/accepted — the whole point of the form-coercion helper (string→number) is untested.
-- [LOW] Only CreateOrder/CreateQuotation covered; the ~150 other duplicated coercion sites (invoices/received-invoices/trips/plan) have no NaN test.
+- [HIGH] (line 89-91) totpEnabled is derived from require2FAOptions(), but that query returns the COMPANY-WIDE require*2fa policy flag (verified: src/routes/admin/totp.ts:200-211 reads company_settings.require_2fa), not the user's enrollment — once loaded, the ?? fallback to user.totpEnabled never applies, so DashProfile shows '2FA Aktivní' plus a Deaktivovat button to un-enrolled users whenever the policy is on (blocking enrollment from the profile card) and 'Neaktivní' plus an enable button to enrolled users when it's off; the per-user totp_enabled endpoint (totp.ts:190-197) exists but is never queried. *(verified)\_
+- [LOW] (line 86-88) dashboardOptions() types the payload as Record<string, unknown> and the page force-casts it with 'as DashData | undefined' — an unvalidated cast that hides shape drift; the DashData type belongs on the queryOptions in lib/queries/dashboard.ts.
+- [LOW] (line 86-87, 309-313) A failed dashboard query is silently swallowed: on error dashLoading goes false and every widget renders with undefined/empty data, with no isError check, alert, or retry affordance anywhere on the page.
 
-## src/__tests__/setup.ts
+## src/admin/pages/InvoiceDetail.tsx
 
-- [LOW] Loads .env.test but doesn't assert it exists or that DATABASE_URL targets a TEST db (vitest.config also loads it with override:true — redundant); a missing .env.test silently runs against whatever env is present (non-test-DB risk).
+- [HIGH] (line 728) Edit-mode hydration overwrites each item's persisted per-line VAT rate with the invoice-level rate (`vat_rate: Number(inv.vat_rate) || 21`) even though invoice*items.vat_rate is a real DB column returned per-item by the detail endpoint — re-saving a mixed-rate invoice silently corrupts per-line VAT rates in the DB, and the edit form plus the paid view's totals (1544-1587, via createTotals over the hydrated items) display wrong VAT; the `|| 21` also turns a legitimate 0% rate into 21% (same falsy-zero at line 689). *(verified)\_
+- [HIGH] (line 1891-1902) Editing 'Text fakturace (na PDF)' on an existing invoice/draft is silently lost: the payload includes billing*text (line 985-998) but UpdateInvoiceSchema (src/schemas/invoices.schema.ts:46-67, plain z.object) has no billing_text field, so Zod strips it before updateInvoice (which supports it via strFields) — the user sees a success toast while the change is dropped. *(verified)\_
+- [MEDIUM] (line 951-953) Post-save PDF regeneration error is silently swallowed (`void apiFetch(...).catch(() => {})`) with no log or user feedback — the stored PDF stays stale/missing after an edit and the later 'Zobrazit fakturu' fails confusingly; violates the repo's never-silently-swallow rule (the adjacent comment does not justify the silence).
+- [MEDIUM] (line 1102) `if (isEdit && !invoice) return null;` renders a blank page while the detail query loads and PERMANENTLY blank when it fails (404/network) — invoiceQuery.isError is never handled, no error message or retry path.
+- [MEDIUM] (line 994) Submit coerces an empty quantity to 0 (`Number(item.quantity) || 0`) and the number inputs explicitly allow min "0" (lines 323, 425), but the server schema uses positiveNumberFromForm (> 0), so a 0-quantity line 400s the entire save with a raw Zod message; client-side validation (970-980) never checks quantities, and the comment claims the coercion makes the payload safe.
+- [LOW] (line 1055) Dead parameter: handleViewPdf(\_lang) ignores the language argument that both call sites pass (invoice.language || "cs") — the endpoint serves the stored file regardless.
+- [LOW] (line 624) Duplicated state: `notes` mirrors form.notes/invoice.notes (set once at line 703) and is used only in the paid read-only view (1595-1597) — should be derived rather than separate state.
+- [LOW] (line 1814-1823) Dead code: the 'cancelled'/'stornovana' variant/color branches can never trigger — VALID_TRANSITIONS in invoices.service.ts only yields ["issued"]/["paid"], and the button label falls back to the raw status string (line 1829) instead of statusLabel like the confirm dialog does.
+- [LOW] (line 1012) Fragile route-state coupling: /invoices/new and /invoices/:id are sibling routes rendering the same un-keyed component (AdminApp.tsx:156-157), so React preserves the instance across navigate() after create; the one-shot dataReady-gated hydration effects (658-659, 753-754) never re-run and are compensated only by the invoice-number resync effect (645-653) — any future direct navigation between invoice ids or detail→new will show stale form state.
 
-## src/__tests__/warehouse.test.ts
+## src/admin/pages/Invoices.tsx
 
-- [MEDIUM] Shared `counter` for location codes + per-describe createdItemId/createdCategoryId in closure → tests within a describe are order-dependent (one early failure cascades).
-- [LOW] "deactivates an item (soft delete)" actually asserts a HARD delete (404) — name lies and would mask a future intended soft-delete; FIFO verified only by summed batch quantity, never that the OLDEST batch is consumed first (core stock-valuation logic unverified); no partial-issue-across-batches / negative-qty rejection / reservation+issue-simultaneous-subtraction tests; hardcoded item_number "ITM001" + item_id:1 in a 403 test (fragile).
+- [MEDIUM] (line 215, 276-297, 736-740) Search input is not debounced (sibling IssuedOrders.tsx uses useDebounce 300ms): every keystroke re-keys BOTH the paginated list query and the totals query, firing two network requests per character typed.
+- [MEDIUM] (line 334-354, 552-557) Mark-as-paid StatusChip is clickable for any user with only invoices.view, but PUT /invoices/:id requires invoices.edit (invoices.ts:181) — view-only users get a guaranteed-403 control; the irreversible-from-the-list mark-paid also fires with no confirmation, unlike delete which is both permission-gated and confirmed.
+- [LOW] (line 804) Delete-confirm message interpolates deleteConfirm.invoice?.invoice_number raw — the column is nullable (drafts, schema.prisma:218; the list at line 530 uses documentNumberLabel for exactly this) so deleting a draft shows 'smazat fakturu "null"'; the Invoice type in lib/queries/invoices.ts also wrongly declares invoice_number: string (non-null), hiding this.
+- [LOW] (line 611) hasPermission("invoices.view") guard around the PDF IconButton is dead code — the whole page already returned <Forbidden/> at line 305 when that permission is missing, so the check is always true.
 
-## Suite-level (tests)
+## src/admin/pages/IssuedOrderDetail.tsx
 
-- [MEDIUM] Server-side only — ZERO frontend/component tests: React Query mutations, api.ts token-refresh/dedup, UI VAT/number formatting, and permission-gated rendering are entirely unverified.
-- [LOW] buildApp/generateToken/no-perm-user bootstrap copy-pasted across ai/plan/warehouse tests instead of helpers.ts (~150 lines of drift-prone duplication).
+- [HIGH] (line 606-611) Hydration coerces with falsy-fallbacks on legitimate zeros: quantity: Number(it.quantity) || 1 turns a saved quantity of 0 into 1, and vat*rate: Number(it.vat_rate) || Number(d.vat_rate) || 21 turns a saved 0% VAT line (0 is a valid VAT_OPTIONS choice, e.g. reverse charge) into 21%/order default — the wrong value is displayed immediately and silently persisted on the next save, changing the order's totals. *(verified)\_
+- [HIGH] (line 826-839) handleStatusChange never mirrors the new status into form.status (handleSubmit does at 797-799, and the one-shot hydration won't re-run since dataReady stays true), so after every transition the StatusChip (938), the `editable` flag (651), and the delete-button gate `form.status !== "completed"` (1080) all use the stale status — e.g. a just-completed order still shows an enabled Delete button (and per the comment at 1074-1077 the backend does not reject that delete). _(verified)_
+- [MEDIUM] (line 885-890) If the detail query errors (404/network), dataReady never becomes true (hydration bails at !detailQuery.data), so the page renders <LoadingState/> forever with no error message — detailQuery.isError is checked only to skip the first spinner, never to surface the failure.
+- [MEDIUM] (line 786-788) Fire-and-forget NAS PDF-archive call swallows all failures with a bare .catch(() => {}) — no console.error, no toast — violating the repo rule that even non-fatal failures must be logged; an order whose PDF never archived to NAS fails completely silently.
+- [MEDIUM] (line 651, 1003-1014, 1040-1054) Save paths aren't gated on orders.edit: `editable` ignores permissions and the "Uložit koncept" / "Uložit" buttons render for any user with only orders.view, while PUT /issued-orders/:id requires orders.edit (issued-orders.ts:118) — view-only users get a fully editable form whose save always 403s, inconsistent with the gated "Odeslat" (1015) and transition buttons (1056).

-- Clean — PreToolUse block-env + PostToolUse prettier hooks. (Prettier-not-a-declared-dep is captured at PROJECT-LEVEL.)
+- [MEDIUM] (line 134-146) Query errors are silently swallowed: no isError handling on either useQuery and the app's QueryClient (src/admin/lib/queryClient.ts) has no global QueryCache onError, so a 403/500/network failure renders 'Žádné čekající žádosti' as if nothing awaits approval instead of surfacing an error.
+- [LOW] (line 141-146) Unchecked `as RawLeaveRequest[]` casts over queries that lib/queries/leave.ts types as Record<string, unknown>[] — the payload type (incl. Prisma relation names) should live on leavePendingOptions/leaveProcessedOptions via jsonQuery<RawLeaveRequest[]> instead of a page-level assertion that hides server payload drift.
+- [LOW] (line 137-140) The lazily-enabled processed query has no loading state: switching to the 'Vyřízené' tab shows the 'Zatím žádné vyřízené žádosti' empty state (lines 429-437) while the fetch is still in flight, because undefined data falls back to [] and only the pending query's isPending gates LoadingState.

-- [LOW] Permission allowlist contains stale entries pointing at the OLD PHP app (find ...boha-app ...\*.php, lines 4-9) — harmless (gitignored, local-only) but dead config from the pre-rewrite project.
+- [MEDIUM] (line 160, 219-220) `minHeight/maxHeight: ["100vh", "100dvh"]` looks like a CSS fallback but in MUI sx an array is responsive breakpoints — xs (phones) gets 100vh and only sm+ gets 100dvh, giving mobile (where dvh matters) the exact phantom-scroll/mis-centering behavior commit 78cd7cf just fixed in the shell; should be a plain "100dvh" (or a real @supports fallback).
+- [LOW] (line 256) Hardcoded decorative orb color `rgba(120, 119, 198, 0.13)` bypasses the theme.vars convention (the sibling orb at line 241 correctly uses `rgba(var(--mui-palette-primary-mainChannel) / 0.16)`), so it doesn't adapt across color schemes.
 
-## CLAUDE.md
+## src/admin/pages/NotFound.tsx
 
-- [LOW] Otherwise excellent and current (counts verified: 52 models, 17 test files/195 tests, 114 admin tsx). One doc-vs-code drift: it states `vatFromGross` (gross VAT) is used "by both the manual form and the AI import," but the JSON single-create path in received-invoices.ts still uses the net `amount*rate/100` formula (see that file's [HIGH]) — the convention is documented as fully applied when one code path was missed. Strength worth preserving: the conventions section + the 2026-06-06 audit reference keep entropy in check.

+- [MEDIUM] (line 125-136) emptyForm is a module-level constant, so created_at: todayLocalStr() is evaluated once at first lazy-load of the page; in a long-lived SPA tab, every new offer created on a later day (e.g. after midnight) defaults to the stale date — the helper must be called at state-init time, not module scope.
+- [MEDIUM] (line 741-743) Create-mode dirty snapshot is captured during the first render, before the async initializers run (next-number effect at 698-704 sets quotation_number, company-settings effect at 580-594 sets currency/vat_rate), so an untouched 'Nová nabídka' page becomes permanently isDirty and fires a spurious beforeunload 'unsaved changes' prompt; also a ref write during render (side effect in render phase).
+- [MEDIUM] (line 679-681) Lock acquisition result is never inspected and errors are swallowed with a bare .catch(() => {}): a 423 'locked by another user' response (race where two users open the offer within the lock window) is silently ignored, the page stays editable, and the server PUT (quotations.ts:285-318) enforces no lock ownership — silent last-write-wins overwrite.
+- [MEDIUM] (line 711-725) Heartbeat interval (10 s) exactly equals the server's LOCK_TIMEOUT_MS (10 s, quotations.ts:25) with zero safety margin; browser background-tab timer throttling (or laptop sleep) lets the lock expire mid-edit, after which heartbeats become owner-scoped no-ops and the user keeps editing unaware that another user can acquire the lock and be overwritten on save.
+- [MEDIUM] (line 847-851) Post-save PDF generation/NAS archival (offers-pdf?save=1) failure is silently swallowed by an uncommented bare .catch(() => {}) — no log, no toast — while the user is shown a success message; violates the 'never silently swallow, log at minimum' rule and leaves the offer without its archived PDF ('PDF soubor nenalezen' surfaces only much later).
+- [MEDIUM] (line 823) Client coerces an emptied quantity input to 0 (Number(x) || 0) but the server schema requires > 0 (QuotationItemSchema.quantity = positiveNumberFromForm, offers.schema.ts:14), and handleSave's pre-validation (805-811) never checks item quantities — saving with a cleared/zero quantity 400s the whole form with only a generic toast and no field-level error.
+- [LOW] (line 817) const payload: any defeats type-checking of the request body and leaks internal fields (\_key, existing item id) to the API — harmless today only because the server schema is a non-strict z.object that strips unknown keys.
+- [LOW] (line 1733) Reorderable/removable scope sections are keyed by array index (key={idx}) while the items list correctly uses stable \_key; swap/remove re-associates DOM state (focus, Quill editor instance) with the wrong section — content stays correct only because all inputs are controlled.
+- [LOW] (line 1023-1028) Permission gate requires offers.edit just to open an active offer's detail (offers.view only suffices for invalidated/completed), even though the page already has a complete readOnly rendering mode (used for lock-by-other) — a view-only user is inconsistently Forbidden from viewing active offers.

+- [LOW] (line 717) hasPermission("offers.view") guard inside the actions column is always true (the page already returned <Forbidden/> at line 436 without it) — dead check.
+- [LOW] (line 398-434) Mutations type TOut as { message?, error? } but useApiMutation resolves result.data (e.g. {id}) — the server's top-level success message is never surfaced, so data?.message in onSuccess is always undefined and the fallback string always shows; the typing misrepresents the actual payload.
+
+## src/admin/pages/OffersCustomers.tsx

+- [MEDIUM] (line 325-335) Submit payload filters out empty custom fields but customer_field_order (getFullFieldOrder, lines 224-244) is built from UNFILTERED customFields indices — if an empty row precedes filled ones, the saved custom_N keys point at shifted indices, producing wrong/phantom field ordering in the PDF address block and on re-edit.
+- [LOW] (line 185-222) Same envelope-typing issue as Offers.tsx: TOut typed { message?, error? } but useApiMutation returns the data payload, so data?.message is always undefined and server success messages are never shown.

+- [MEDIUM] (line 392-397) default_price: parseFloat(e.target.value) yields NaN when the price field is cleared (no guard/fallback); the controlled input gets value={NaN} (React warning, field blanks) and JSON.stringify serializes NaN as null, which the server's numberFromForm rejects → save fails with an opaque 400. This is the client-side variant of the banned NaN-coercion bug class.
+- [MEDIUM] (line 490-527) ScopeTemplatesTab openEdit silently does nothing when the detail response is success:false (404 deleted template, server error returning JSON, etc.) — only thrown/network errors reach the catch+alert; the failure path is swallowed and the edit click appears to do nothing.
+- [LOW] (line 189-213, 445-472) Same envelope-typing issue: mutation TOut typed { message?, error? } but useApiMutation resolves result.data ({id} or null), so data?.message is always undefined and server messages like "Položka byla uložena" are never displayed.

+- [MEDIUM] (line 163-182) statusMutation and orderDeleteMutation invalidate only ["orders","invoices"], but the server propagates status 'dokoncena' to the linked project (orders.service.ts ORDER_TO_PROJECT_STATUS) and deleteOrder deletes linked projects — ["projects"] cache stays stale after both actions, violating the invalidate-every-touched-domain convention (the page's own dialogs at 790/806 even announce the project side-effects).
+- [MEDIUM] (line 132-135) isDirty useMemo reads initialNotesRef with deps [notes]: (a) the falsy guard `!initialNotesRef.current` means orders whose saved notes are "" can never become dirty, so the beforeunload guard never arms on the common empty-notes case; (b) after handleSaveNotes updates the ref (line 206) the memo is not recomputed, so the unsaved-changes prompt incorrectly persists after a successful save.

+- [LOW] (line 9-11) Lazy-loading is inverted: the DEFAULT tab component (IssuedOrders, rendered for tab=vydane) is React.lazy with a Suspense fallback flash on every cold visit, while the secondary-tab ReceivedOrders is eagerly bundled into this chunk even when never shown.
+
+## src/admin/pages/PlanWork.tsx
+
+- [MEDIUM] (line 261-263) goToToday passes a raw local-time `new Date()` as the anchor, but usePlanWork derives the visible range with UTC getters (startOfWeek/getUTCMonth) — between local midnight and 01:00/02:00 Prague the UTC date is the previous day, so 'Dnes' shows the previous week (on Mondays) or previous month (on the 1st), disagreeing with the local-time todayIsoLocal() highlight/past-date gate; same banned UTC-today class as toISOString date-slicing.
+- [MEDIUM] (line 185) any-typed mutation payloads/response defeat usePlanWork's typed contracts (PlanEntryBody/PlanOverrideBody etc.): `const data: any` here plus `body: any` in saveEntry (394), updateEntryFn (411), saveOverride (475) and updateOverrideFn (490) — field accesses like body.user_id/body.date_from/body.shift_date and summary.skipped_days compile with no checking, so a renamed field silently breaks pulse targeting/rollback.
+- [LOW] (line 27) Stale comment claims 'plan.css is imported once globally in AdminApp.tsx' — no .css files exist anywhere under src/admin (plan.css was removed in the MUI migration; PlanGrid.tsx:18 documents the replacement).
+- [LOW] (line 137) Project selector source is hard-capped at projectListOptions({ perPage: 200 }) with no pagination/search — once the company exceeds 200 projects (one is auto-created per order) older projects silently disappear from the plan modal's picker.
+
+## src/admin/pages/ProjectDetail.tsx
+
+- [MEDIUM] (line 139-141) Type lie breaks the inactive-assignee retention: ProjectData.responsible_user_id is declared string but the API returns the Prisma Int (projects.service.ts spreads the row; schema.prisma `responsible_user_id Int?`), so `String(u.id) === assignedUserId` is never true — a project assigned to a now-inactive user drops them from the select (out-of-range/empty value) despite the comment's stated intent, and form.responsible_user_id holds a number behind a string type.
+- [MEDIUM] (line 600-601) Linked order's status is rendered via the local project STATUS_LABELS map (keys aktivni/dokonceny/zruseny), but order statuses are prijata/v_realizaci/dokoncena/stornovana — no key ever matches, so the raw DB value (e.g. 'v_realizaci') is always shown; should use ORDER_STATUS/statusLabel from lib/documentStatus, the documented single source of truth this duplication regresses.
+- [MEDIUM] (line 177-190) projectSaveMutation invalidates only ["projects","warehouse"], but orders embed project data (OrderDetail renders order.project.project_number — name) — renaming or restatusing a project leaves linked order queries stale, violating the 'entity B's CRUD invalidates embedding domain A' convention (should also invalidate ["orders"]).
+
+## src/admin/pages/Projects.tsx

+- [HIGH] (line 153-154) Create modal submits createForm verbatim (line 207) with start*date/end_date initialized to "" — server CreateProjectSchema uses isoDateString.nullish(), which rejects "" (verified: safeParse fails with 'Datum musí být ve formátu YYYY-MM-DD'), so creating a project without filling BOTH dates (the default path; only 'name' is validated client-side) always 400s; the fields must be sent as null/omitted when empty. *(verified)\_

+- [MEDIUM] (line 249) Search input is not debounced (sibling pages Projects/ReceivedOrders use useDebounce(300)); raw `search` keys both the list query (266-274) and the totals query (285-291), so every keystroke fires two fresh network requests.
+- [MEDIUM] (line 389-395) removeUploadFile deletes uploadErrors[idx] but does not reindex higher-keyed entries while uploadFiles/uploadMeta shift down — after removing a file, remaining validation errors render on the wrong file cards (or vanish).
+- [LOW] (line 656-662) The unpaid StatusChip's toggle-to-paid onClick is not gated by hasPermission("invoices.edit"), unlike the edit/delete buttons (707, 717) — users without edit permission get a clickable chip that fails with a server-error alert.

+- [MEDIUM] (line 1172-1173) Admin-role info banner uses solid bgcolor "info.light" + color "info.dark" — violates the documented MUI convention (channel-alpha washes via theme.vars, never solid .light fills; info.light stays a light fill in dark mode and clashes with the dark scheme).
+- [LOW] (line 193-198) Redundant double-await: apiFetch(...).then(r => r.json()) is already resolved by Promise.all, so `const rolesResult = await rolesRes` / `await permsRes` are no-op awaits on plain values (confusing dead code).
+- [LOW] (line 917-923) Number(e.target.value) coercion (also at 928-938, 974-1010, 1111-1121) silently turns a cleared numeric field into 0; server numberInRange(1,…) then 400s the entire settings save for max_login_attempts/lockout_minutes/max_requests_per_minute, while break_threshold_hours=0 is silently accepted — no empty/NaN guard client-side.
+- [LOW] (line 680) `systemInfo as Record<string, any>` any-cast discards all typing for the system-info rendering (si.memory?._, si.database?._, si.nas?.\*) — a renamed backend field would silently render undefined instead of failing typecheck.

+- [HIGH] (line 324-336) Stat-card totals (Počet jízd / Celkem naježděno / Služební / Soukromé, lines 458-482) are computed from tripListOptions({}) whose backend response is paginated at the default 25 rows — once a user has >25 trips the totals silently undercount (count caps at 25); the header (435-439) additionally labels these stats with the current month although the query has no month filter. _(verified)_
+- [MEDIUM] (line 161-166) No isError handling for the trips query (and no global QueryCache onError): on fetch failure tripsLoading ends, trips=[] and the page shows zeroed stats plus the misleading empty state "Zatím nemáte žádné záznamy jízd" (509-518) — error silently swallowed and presented as 'no data'.
+- [LOW] (line 186) Write-only state `const [, setLastKm] = useState(0)` — the value is never read; the setLastKm calls (220, 227, 236, 251, 268) only trigger pointless re-renders. Dead state to remove.
+- [LOW] (line 282-283) Falsy-zero validation: `if (!form.start_km)` rejects a legitimate 0 starting odometer (the last-km prefill at 229 sets start_km to numeric 0 for a vehicle with no trips, then validation blocks submit with 'Zadejte počáteční km').

+- [HIGH] (line 295, 665-676) Edit modal offers a vehicle Select and sends vehicle*id in the PUT body, but UpdateTripSchema (src/schemas/trips.schema.ts:23-31) has no vehicle_id and the PUT /trips/:id handler never applies it — changing the vehicle is silently dropped while the UI reports 'Upraveno' success. *(verified)\_
+- [MEDIUM] (line 220-229) List fetched with perPage: 100 (server also clamps maxLimit=100) and the page has no pagination UI — months with >100 trips silently truncate the table, the client-computed stat totals, and the printed 'Kniha jízd' report (wrong totals with no indication; pagination meta is discarded by jsonQuery).
+- [LOW] (line 285-289) Client km validation is vacuous when a field is empty: parseInt('') yields NaN and NaN comparisons are false, so the end>start guard passes and the server rejects with the misleading message 'Číslo nesmí být záporné' (nonNegativeNumberFromForm NaN refine).

+- [MEDIUM] (line 149-163) BatchSelect's "-- auto FIFO --" option is a no-op once a batch is chosen: selecting it yields `Number("") === 0`, `batches.find` returns undefined, and `onChange` (whose signature can't even pass null) never fires — the user cannot revert a row to auto-FIFO and stays pinned to a manually picked batch, with stale unit*price, unless they delete and re-add the row. *(severity adjusted by verification: Mechanics confirmed: Select (src/admin/ui/Select.tsx:31) emits "" for the auto-FIFO option, and WarehouseIssueForm.tsx:151-154 does Number("")===0 → find→undefined → guarded onChange (typed (number, number), line 124) never fires, so the row stays pinned to the picked batch with no other reset path (ItemPicker at line 527 doesn't clear batch*id). However, severity is overstated: the stale unit_price is display-only (buildPayload at lines 342-354 never submits it; the server prices from the batch), the pinned batch is valid user-chosen data that the server validates (warehouse.service.ts:612-628), and delete/re-add-row is an immediate workaround — a real UX/functional gap, not likely practical damage, so MEDIUM.)*
+- [MEDIUM] (line 524-536) Changing a row's item via ItemPicker does not reset batch_id/reservation_id/unit_price — the stale batch from the previous item is kept (BatchSelect renders an out-of-range value against the new item's batch list) and submitted, which the server rejects at confirm with a confusing 400 "Šarže ID X nepatří k položce ID Y" (verified in warehouse.service.ts:614).

+- [LOW] (line 18) Math.min/Math.max clamps only the _displayed_ page without notifying the parent via onChange, so when page > pageCount (e.g. last-page items deleted) the parent keeps fetching the stale out-of-range page showing an empty list while the pager highlights pageCount as selected — and clicking that highlighted button fires no onChange, so it can't self-correct.

+- [MEDIUM] (line 102-111) Type-safety hole: `options.headers as Record<string, string>` — RequestInit.headers may be a Headers instance (spreads to {}, silently dropping all caller headers incl. Content-Type) or a [string,string][] (spreads to numeric keys); also the case-sensitive `!headers["Content-Type"]` check adds a duplicate header if a caller used `content-type` lowercase. Normalize HeadersInit instead of casting.
+- [LOW] (line 143-153) If the 401-triggered refresh reports success but getTokenFn() returns null, the retry re-sends the original stale `Authorization` header (set at line 115), guaranteeing a second 401 that is returned to the caller without setSessionExpired() being flagged.
+
+## src/admin/utils/attendanceHelpers.ts

+- [LOW] (line 142-154) calcFormWorkMinutes guards only the time fields; with an empty date (useAttendanceAdmin.ts:787 initializes arrival_date:"") it builds `"T08:00"` → Invalid Date → NaN, and `Math.max(0, Math.floor(NaN))` is NaN — rendered as "NaN:NaN" via formatMinutes and silently skipping the `totalWork > 0` project-hours validation in useAttendanceAdmin.validateProjectLogs. Should return 0 when any needed date/time is missing or the result is NaN.
+- [LOW] (line 251) calculateNightMinutes treats equality as cross-midnight: `if (endMs <= startMs) endMs += 24h`, so a record with arrival_time === departure_time (zero-length shift; calculateWorkMinutes returns 0 for it) is counted as a full 24h shift and yields 480 night minutes on the payroll print. Should be `<` with the `===` case returning 0.

+- [LOW] (line 21) `process.env.DATABASE_URL as string` with no import of ./config/env (or required()) makes the module depend on every entry point loading dotenv first; if one forgets, the failure is a cryptic `new URL(undefined)` "Invalid URL" TypeError instead of the clear missing-env error (all current entry points — server.ts, seed.ts, scripts — happen to do it right, verified).

+- [MEDIUM] (line 338-441) POST / punch, leave, and standard-create paths are guarded only by requireAuth — any authenticated user without the attendance.record permission can punch in/out and create their own attendance/leave records via the API (only cross-user writes check attendance.manage; the frontend gates the UI on attendance.record but the backend never does), affecting leave balances/payroll data.
+- [MEDIUM] (line 181-184) action=projects branch has no permission check at all (every other action in this GET handler is explicitly guarded) — any logged-in user can list all active projects (id, name, project_number), violating the 'GET reads need a permission guard, not bare requireAuth' convention.
+- [LOW] (line 263-368) request.body is cast to Record<string, unknown> without a null guard; a POST with no body/content-type leaves rawBody undefined and `rawBody.punch_action` (line 368) throws a TypeError → 500 instead of a 400.

+- [MEDIUM] (line 61-67) Paginated list uses orderBy { created_at: order } with no { id } tiebreak — created_at is second-precision, so same-second rows (common for bulk operations in audit logs) make page boundaries non-deterministic (rows duplicated/skipped across pages); violates the documented 'always tiebreak a timestamp sort with id' rule.
+- [LOW] (line 15-18) AuditCleanupSchema uses bare z.number() for `days` instead of the mandatory numberFromForm coercion helper from src/schemas/common.ts — a form-stringified "30" is rejected with a 400.

+- [MEDIUM] (line 116-190) Login-token consumption is not atomic: the token is SELECT … FOR UPDATE'd in one transaction (116-150) but only deleted at line 188 after that transaction committed and after TOTP verification — the lock is released without consuming the token, so concurrent requests can both pass validation with the same single-use login token, and the loser's totp_login_tokens.delete then throws P2025 → unhandled 500.
+- [MEDIUM] (line 161-200) A failed TOTP code neither consumes the login token nor increments failed_login_attempts/locked_until (the success path resets them at 193-200 but there is no failure counterpart) — code guessing against a stolen password is bounded only by the per-IP rate limit (default 5/min) for the 5-minute token lifetime.
+- [LOW] (line 203-240) Duplicated token-issuance logic: re-implements access-token signing + refresh-token creation inline via dynamic import("jsonwebtoken")/import("../../services/auth") instead of reusing the existing generateAccessToken/refresh-token helpers in services/auth.ts — drift risk between the two issuance paths.

+- [MEDIUM] (line 33-45, 73-114) is_default is not exclusive: creating or updating an account with is_default=true never clears the flag on the previous default, so multiple defaults can coexist and InvoiceDetail.tsx (`bankAccounts.find(a => a.is_default)`) picks one arbitrarily.

+- [MEDIUM] (line 145-364) GET / is guarded only by bare requireAuth and returns the FULL settings row — including security configuration (max_login_attempts, lockout_minutes, max_requests_per_minute, require_2fa), SMTP sender, alert/notify emails, and all numbering patterns — to every authenticated user; convention requires permission-guarded reads (writes need settings.company/settings.system, the read needs nothing).
+- [LOW] (line 197-313) The 'race-safe' create-on-GET transaction takes no row lock and company_settings has no unique constraint, so under MySQL REPEATABLE READ two concurrent first-GETs can both insert a settings row (the comment overstates the guarantee); it is also an unaudited write triggered by a GET.
+- [LOW] (line 317-322) Every settings GET loads both logo BLOB columns (up to 5 MB each) just to compute the has_logo/has_logo_dark booleans — a `where: { logo_data: { not: null } }` existence check would avoid pulling the blobs.
+- [LOW] (line 483-511) Dead re-validation: strFields String() coercion and the numFields Number()+isFinite guards re-check values already validated/coerced by UpdateCompanySettingsSchema (nonNegativeNumberFromForm/numberInRange/emailOrEmpty), so the 400 branches at 489-490 and 507-508 are unreachable.

+- [LOW] (line 218-224) PUT custom-fields handling is asymmetric with company-settings: sending custom_fields without customer_field_order silently wipes the stored field order (encodeCustomFields gets undefined → []), and sending customer_field_order alone is ignored entirely (company-settings PUT merges with the existing blob; this one does not). Latent today because OffersCustomers.tsx always sends both.
+- [LOW] (line 250-265) FK-reference pre-check (4 counts) runs outside any transaction before the delete — a quotation/order/invoice/project linked between the check and the delete yields an FK-violation 500 (or an orphaned reference if the DB lacks the constraint); TOCTOU race.

+- [MEDIUM] (line 418-435) VAT recapitulation hardcodes rates [21, 12, 0]; items with any other vat_rate (e.g. legacy Czech 15%/10% on pre-2024 invoices) are silently omitted from the recap table while still counted in totals/vatDetailHtml, so the tax recap no longer sums to the invoice total.
+- [LOW] (line 408-410) QR (SPAYD) generation catch swallows the error without logging — a QR failure is not an expected-condition existence check, so per the repo rule it should at least request.log.warn.

+- [LOW] (line 34-40) The onRequest hook runs before the preHandler auth guards, so unauthenticated GETs to any invoice path trigger the markOverdueInvoices DB writes (hourly-throttled and internally error-logged, but still a pre-auth write trigger).
+- [LOW] (line 142-150) CreateInvoiceSchema accepts status as a free string (max 20, no enum), so POST / with e.g. status "foo" consumes an official invoice number (createInvoice numbers anything non-draft) and creates a record outside the VALID_TRANSITIONS state machine (no valid transitions out).

+- [LOW] (line 37-39) customer_id/month/year query filters coerced with raw Number() and no NaN guard — a malformed value becomes NaN, which the service's falsy check silently drops, returning the unfiltered list instead of a 400 (same on /stats lines 69-71).
+- [LOW] (line 98-164) All three logAudit calls (create/update/delete) omit oldValues/newValues — the repo convention says to pass them so the audit diff is stored (most valuable for update/delete of financial documents).
+
+## src/routes/admin/leave-requests.ts
+
+- [MEDIUM] (line 195-299) Vacation-balance cap check (195-210) runs BEFORE the transaction and the in-transaction leave_balances read-modify-write (270-299) takes no SELECT…FOR UPDATE lock — concurrent approvals for the same user can overdraw the balance or lose an increment; the repo convention mandates row locking for balance mutations (cf. attendance.service lockUserRow).
+- [MEDIUM] (line 49) orderBy: { created_at: order } with no { id } tiebreak — created_at is second-precision, so paginated ordering is non-deterministic for same-second rows (documented ALWAYS-tiebreak rule).
+- [MEDIUM] (line 39-42) Unvalidated `?status=` values are passed straight into the Prisma enum filter (equals or { in }) on leave_requests_status — an invalid status (or trailing comma yielding "") throws a Prisma validation error → 500 instead of 400.
+- [LOW] (line 71-78) Dead code: the VALID_LEAVE_TYPES re-check duplicates CreateLeaveRequestSchema's z.enum(["vacation","sick","unpaid"]) which has already validated body.leave_type (also line 19).
+- [LOW] (line 375-381) DELETE checks request status (400) before ownership (403), so any authenticated user can probe by id whether another user's leave request exists and whether it is still pending — check ownership first.
+- [LOW] (line 251-260) Duplicate-attendance check runs one tx.attendance.findFirst per business day in a loop (N sequential queries inside the transaction) — a single findFirst with shift_date: { in: [...] } would do.
+- [LOW] (line 116-123) logAudit calls throughout the file (create 116, approve 329, reject 351, cancel 387) omit oldValues/newValues, so no diff (e.g. previous status) is stored per the audit convention.
+
+## src/routes/admin/offers-pdf.ts
+
+- [MEDIUM] (line 752-771) save=1 path ignores saveOfferPdf's return value (it returns null on a failed NAS write, only console.error-ing inside the manager) and always replies success 'PDF uloženo'; when NAS is unconfigured or quotation_number is empty it silently falls through to serving the HTML instead of reporting the save was skipped — NAS archival failures are invisible to callers.
+- [LOW] (line 31-49) formatCurrency drops the negative sign for USD and GBP (Math.abs(n).toFixed(...) without re-prepending '-' as formatNum does for EUR/CZK), so negative line items (discounts) render as positive amounts in those currencies.
+- [LOW] (line 220) GET endpoint with a write side effect (?save=1 writes/overwrites the archived PDF on the NAS) is gated only by offers.view — a view-only user can trigger NAS writes; contrast with orders-pdf.ts which deliberately gates its write-ish path behind orders.edit.
+
+## src/routes/admin/orders-pdf.ts
+
+- [LOW] (line 62-84) This cleanQuillHtml copy drifted from the offers-pdf/invoices copies: it strips only 'javascript:' in href and does not strip 'data:'/'vbscript:' schemes or the src attribute (offers-pdf.ts lines 78-87 does, and its comment claims the copies match). Defense-in-depth only since DOMPurify.sanitize runs first, but the triplicated helper invites exactly this drift — extract it to a shared util.
+
+## src/routes/admin/orders.ts
+
+- [MEDIUM] (line 134-141) The multipart parts() loop only consumes file parts named 'attachment'; any file part with another fieldname is skipped without draining its stream, and per @fastify/multipart 9.4.0 docs an unconsumed file stream means the iterator promise never fulfills — the request hangs indefinitely (Fastify has no default connection timeout). Add an else branch that drains (part.file.resume() or await part.toBuffer()).
+- [MEDIUM] (line 342-344) DELETE body bypasses parseBody/Zod (raw 'request.body as Record<string, unknown>') and '!!body?.delete_files' is truthy for the string "false" — convention requires validating every body (booleanFromForm exists exactly for this string-boolean coercion).
+- [LOW] (line 245-247) Dead code: 'if (!quotationId || isNaN(quotationId))' can never trigger — CreateOrderFromQuotationSchema's intIdFromForm already guarantees a valid positive integer (verified in src/schemas/orders.schema.ts).

+- Clean
+
+## src/routes/admin/profile.ts
+
+- [MEDIUM] (line 70-86) The email-uniqueness 'transaction' does not prevent the race its comment claims: a plain findFirst inside $transaction takes no lock (MySQL REPEATABLE READ won't serialize two concurrent checks), so the real backstop is the @unique index on users.email — but the resulting P2002 is NOT caught (only the 'EMAIL_EXISTS' Error is) and rethrows as a 500. Convention requires catching P2002 → 409.
+- [LOW] (line 88-95) logAudit for the profile update passes only a description — no oldValues/newValues diff for the email/first_name/last_name change (convention: pass old/new values so the diff is stored; exclude password_hash).

+- [MEDIUM] (line 26-31) DeleteProjectSchema uses the banned raw z.union([z.boolean(),z.string(),z.number()]).transform(...) idiom for a form boolean instead of the mandated booleanFromForm helper from src/schemas/common.ts (which does exactly this).
+- [LOW] (line 90, 128, 161) `(result as any).status` any-casts on service results defeat type-checking; the service returns a typed {error,status} shape that could be narrowed instead.

+- [LOW] (line 189-217) POST /:id/lock reads then updates the lock without a transaction/row lock — a TOCTOU race lets two users both pass the freshness check and both acquire the edit lock (advisory lock, low stakes).
+
+## src/routes/admin/received-invoices.ts
+
+- [MEDIUM] (line 142) List orderBy `{ [sortField]: order }` has no `id` tiebreak; created_at is @db.Timestamp(0) (second-precision) and issue_date/due_date are date-only, so paginated results over same-value rows are non-deterministic (skips/dupes across pages).
+- [MEDIUM] (line 390-398, 429-431, 489, 617) issue_date/due_date are validated only as plain strings (schema uses z.string().max(255), not isoDateString), so a malformed value flows into `new Date(String(...))` → Invalid Date written to DB, and in the multipart path Invalid Date.getMonth()/getFullYear() yields NaN month/year persisted to Int columns (crash/data-corruption).
+- [LOW] (line 296-301) File route serves the uploaded `file_mime` with Content-Disposition: inline and no content-type allowlist (upload accepts any mimetype); an uploaded text/html invoice would render inline. Largely mitigated by global nosniff + prod CSP (script-src 'self' blocks inline JS), and requires a privileged uploader.
+- [LOW] (line 382-444) Multipart create writes each NAS file then creates each DB row sequentially with no surrounding transaction; a mid-batch failure leaves partially-created invoices and/or an orphaned NAS file (NAS save precedes the DB create).
+
+## src/routes/admin/roles.ts
+
+- [MEDIUM] (line 83-109) Role-name uniqueness is checked with findFirst BEFORE the create transaction (TOCTOU) and the create has no P2002 catch; roles.name is @unique, so two concurrent creates of the same name surface as an unhandled 500 instead of the intended 409 (violates the in-transaction-uniqueness + P2002 convention).
+- [LOW] (line 151-174) The roles.update (display_name/description) runs outside the role_permissions delete+recreate transaction, so a failure between them leaves the name updated but permissions in an inconsistent state.

+
+- [LOW] (line 83-96, 101-108, 142-154, 179-185, 259-278, 298-305) All logAudit calls in this file omit `entityType`, so audit rows for scope/item templates store entity_type = null (inconsistent with every other route and breaks filtering by entity type).
+
+## src/routes/admin/sessions.ts

Authorization gap allowing trip spoofing for other users.
+- [MEDIUM] (line 73) Paginated list orderBy trip_date (date-only @db.Date) has no `id` tiebreak; with many trips sharing a date this makes skip/take pagination non-deterministic (rows skipped/duplicated across pages).

However, severity is MEDIUM not HIGH: the unique constraint preserves data integrity, the failure is only a wrong status/unhelpful message on the infrequent duplicate-plate path in a rarely-mutated fleet table — a convention/error-reporting gap, not a bug likely to bite in practice.)_

+- [MEDIUM] (line 433-445, 551-559) createOrder explicit order_number path: empty string passes the !== undefined/!== null guard and creates an order numbered "" while skipping number generation; isOrderNumberTaken runs on the base client (not the tx, so the TOCTOU is not closed) and there is no P2002 → 409 catch, so a concurrent duplicate explicit number surfaces as a 500 (convention requires in-tx re-check + P2002 handling).
+- [LOW] (line 576-584) Dead guard: UpdateOrderSchema has no order_number field and z.object strips unknown keys, so body.order_number is always undefined and the 'Číslo objednávky nelze změnit' check can never fire.
+- [LOW] (line 690-741, 755) deleteOrder's warehouse/attendance guard counts refs only for projects fetched BEFORE the transaction, while projects.deleteMany targets order_id — a project linked to the order between the pre-tx fetch and the tx bypasses the guard entirely (its restricted FKs then fail as P2003 → 500), despite the comment claiming the in-tx count closes the window.
+- [LOW] (line 670-677) In the no-items branch the order status update and syncProjectStatus run as two separate non-transactional calls on the base client (the items branch wraps both in a tx), so a failure between them leaves the order and its linked project's statuses diverged.
+
+## src/services/plan.service.ts
+
+- [MEDIUM] (line 586-606) updateEntry validates date_to >= date_from only when BOTH endpoints are in the payload (the Zod refine in plan.schema.ts:36-41 has the same both-present gap), so a partial update of just date_from (or just date_to) can store an inverted range (date_from > date_to) that then matches no day in resolveCell/resolveGrid — the entry silently disappears from the grid.
+- [LOW] (line 681, 747) createOverride and updateOverride return Promise<Result<any>> — the override row type is left as any (entries use the explicit CreatedEntry type), a documented type-safety hole.
+- [LOW] (line 377-378) assertNotPastDate re-implements the local YYYY-MM-DD 'today' computation inline instead of importing the canonical localDateStr from src/utils/date.ts (the convention names that helper as the single source for server-side 'today').
+
+## src/services/planCategory.service.ts
+
+- [MEDIUM] (line 34-79) createPlanCategory runs the uniqueKey probe loop and the create outside any transaction with no P2002 catch — TOCTOU on the key unique constraint: two concurrent creates of the same label pass the probe and the loser surfaces as an unhandled 500, violating the documented 'uniqueness check inside the create transaction + catch P2002 -> 409' rule (the sort_order aggregate at 66-69 has the same unguarded race).
+
+## src/services/projects.service.ts
+
+- [MEDIUM] (line 50) listProjects allows sort=created_at (in ALLOWED_SORT_FIELDS) but orderBy has no { id } secondary sort — second-precision timestamps make paginated ordering non-deterministic (rows can repeat/skip across pages), violating the 'always tiebreak a timestamp sort with id' convention.
+- [LOW] (line 80) project_notes ordered by created_at desc with no id tiebreak — notes created in the same second render in unstable order (same convention as above, unpaginated so lower impact).
+- [LOW] (line 100-135) updateProject takes body as Record<string, any> and re-coerces with raw Number()/new Date(String()) even though the route already validated via UpdateProjectSchema (verified in routes/admin/projects.ts:122-125) — type-safety hole duplicating validation; should accept the inferred UpdateProjectInput type.
+- [LOW] (line 104-109) Dead code: the 'Číslo projektu nelze změnit' guard can never fire — UpdateProjectSchema (z.object, strips unknown keys) has no project_number field, so body.project_number is always undefined after parseBody; an attempted change is silently dropped instead of 400ing.
+- [LOW] (line 94-96) getProject calls nasFileManager.projectFolderExists() — a synchronous directory scan of the SMB NAS share (findProjectFolder uses sync fs APIs, verified in nas-file-manager.ts) — on every project-detail GET; a slow or unavailable NAS blocks the Node event loop for all requests.
+
+## src/services/system-settings.ts
+
+- Clean
+
+## src/services/users.service.ts
+
+- [MEDIUM] (line 321-329) updateUser's transaction catch only maps custom status errors and rethrows everything else — a concurrent username/email write that beats the in-tx uniqueness check throws P2002 and surfaces as a 500; createUser (180-188) catches P2002 -> 409 but updateUser does not, violating the 'catch P2002 -> 409' convention.
+- [MEDIUM] (line 334-350) deleteUser has no last-active-admin guard: updateUser blocks demoting (228-234) and deactivating (248-253) the last active admin, but hard-deleting the sole admin account is allowed (only self-delete is blocked), so any non-admin user with users.delete can leave the system with zero administrators.
+- [LOW] (line 203-256) The admin-role and active-admin-count guards run before/outside the update transaction — check-then-act race: two concurrent demote/deactivate requests for the two remaining admins can both pass count<=1 checks and remove all admins.
+- [LOW] (line 64) listUsers builds the Prisma filter as `const where: any` — untyped filter object hides field-name/shape mistakes from the compiler (projects.service uses Record<string, unknown> for the same pattern).
+
+## src/services/warehouse.service.ts
+
+- [MEDIUM] (line 952) validateIssueReservationRules calls getItemTotalStock(itemId), which queries the GLOBAL prisma client, while the surrounding code uses the passed tx `client` (953) — a non-transactional, unlocked stock read inside confirmIssue's locked transaction (runs on a separate pooled connection, misses in-tx state), exactly the discipline violation getItemAvailableQtyTx's own comment (157-160) warns about.
+- [MEDIUM] (line 352-387) confirmReceipt mutates sklad_item_locations without first locking the affected sklad_items rows (every other stock path — confirmIssue 589-598, cancelIssue 775-784, confirmInventorySession 1132-1136 — does): a concurrent issue-confirm's unlocked read-then-delete of the same location row (683-695) can discard the receipt's just-committed increment (lost update / location drift), and two concurrent first-creates of the same (item, location) row race to P2002 -> 500 (Prisma upsert is not native on MySQL).
+- [MEDIUM] (line 445-532) cancelReceipt's CONFIRMED->CANCELLED path validates batch is_consumed/quantity and reverses item_locations on plain snapshot reads with no lockRowsForUpdate on items/batches (unlike confirmIssue/cancelIssue) — the consumed-check is racy against a concurrent draft-issue create+confirm inside the cancel window (batch delete then fails on the issue_lines FK as a 500), inconsistent with the file's own locking discipline.
+- [LOW] (line 446-450) Redundant per-line query: cancelReceipt re-fetches each batch via tx.sklad_batches.findUnique although item.batch was already loaded by the include at 424 in the same transaction (N+1 duplication).
+
+## src/types/fastify.d.ts
+
+- Clean
+
+## src/types/index.ts
+
+- [LOW] (line 88-94) PaginationMeta requires both limit and per_page, which are always set to the same value (utils/pagination.ts:59 fills per_page: limit) — duplicated field every paginated route must populate twice.
+- [LOW] (line 81-86) ApiResponse lacks the message field that success() actually sends, forcing the ApiResponse<T> & { message?: string } intersection workaround in utils/response.ts:10 — the declared response type understates the real wire shape.
+
+## src/utils/czech-holidays.ts
+
+- [LOW] (line 30-100) Holiday/business-day logic is fully duplicated client-side in src/admin/pages/AttendanceHistory.tsx (getCzechHolidays/getBusinessDaysInMonth reimplemented, lines ~100-145 there) — two sources of truth that can drift if a holiday rule changes.

+- Clean
+
+## src/utils/encryption.ts
+
+- Clean
+
+## src/utils/html-to-pdf.ts
+
+- [MEDIUM] (line 47) Bare `catch {}` swallows the puppeteer launch error without logging before falling back to puppeteer-core — when puppeteer IS installed but launch fails (e.g. missing shared libs, sandbox issue), the real cause is hidden and only the misleading puppeteer-core/CHROMIUM_PATH error surfaces; violates the 'never silently swallow errors, log at minimum' rule (the comment covers only the expected module-absent case).
+- [LOW] (line 99-104) closeBrowser: if `browser.close()` rejects, `browser = null` is never executed (stale dead reference kept) and the rejection propagates out of htmlToPdf's finally block (line 93), masking the original page-close/render error.

+- [MEDIUM] (line 22-25) Replay-protection gap: `counterDelta = Math.min(delta, 0)` records a future-window code (delta=+1, accepted via window:1) as the CURRENT counter, so one period later the same code re-validates at delta=0 with counter = currentCounter+1 > stored and passes auth.ts's `counter <= lastCounter` replay check (auth.ts:167-185) — an intercepted code from a clock-ahead device can be used twice; should record `currentCounter + delta` for the matched window.
+
+## src/vite-env.d.ts
+
+- Clean
 
 ## tsconfig.app.json
-- [MEDIUM] `noUnusedLocals:false`/`noUnusedParameters:false` (compiler won't flag dead code) and tests not included (not type-checked). strict:true, bundler resolution correct.
+
+- [LOW] (line 19-22) Dead/footgun config: the `@/*` -> `src/*` paths alias is used by zero source files and has no matching `resolve.alias` in vite.config.ts — any future `@/` import would typecheck under tsc but fail the Vite build/dev server.
+
+## tsconfig.json
+
+- Clean
+
+## tsconfig.server.json
+
+- [LOW] (line 16-19) Dead '@/\*' path alias: zero server files import via '@/', and tsc does not rewrite aliases at emit, so any future '@/' import would typecheck and build yet crash node dist/server.js at runtime (no tsc-alias/runtime resolver is installed).
+- [LOW] (line 21-30) src/vite-env.d.ts ('/// <reference types="vite/client" />') is matched by include and not excluded, leaking Vite's frontend ambient types (\*.css module declarations, ImportMeta.env) into the server program so bogus asset imports would typecheck.
+- [LOW] (line 29) src/**tests** is excluded from the build but stale pre-exclusion output (9 compiled test files in dist/**tests**/) remains — build:server is plain tsc with no clean step and the release tars dist wholesale, so dead test JS (importing dev-only vitest) ships to production.
+
+## tsconfig.test.json
+
+- [LOW] (line 14-17) Dead '@/\*' path alias duplicated here: no test uses it, and vitest.config.ts has no tsconfig-paths/alias wiring, so an '@/' import in a test would typecheck under tsc -b but fail to resolve at runtime under Vitest.
 
 ## vite.config.ts
-- Clean — react plugin, manualChunks for vendor splitting, es2020 target.
+
+- [MEDIUM] (line 18-25) manualChunks uses substring match id.includes("node_modules/react") which captures every react\* package (react-quill-new, react-is, react-transition-group), not just react/react-dom/react-router — verified in dist-client: the eagerly-loaded 435 KB vendor-react chunk contains the full Quill editor (ql-editor/react-quill markers), defeating lazy-loading of the rich editor and bloating every initial page load; match 'node_modules/react/' etc. with trailing slash instead.
+- [LOW] (line 8-10) server: { port: 3000 } backs the standalone 'npm run dev:client' flow, but there is no server.proxy and the SPA fetches relative '/api/...' URLs, so that documented workflow 404s on every API call; the actual dev flow is Vite middleware-mode inside Fastify (src/server.ts:166), leaving this block dead/misleading.
 
 ## vitest.config.ts
-- Clean — node env, `.env.test` override, `fileParallelism:false` (deliberate, documented), 15s timeouts.
 
-## .env.example
-- [MEDIUM] Stale — missing many env vars config/env.ts reads (ANTHROPIC_API_KEY, NAS_FINANCIALS_PATH, NAS_OFFERS_PATH, SMTP_FROM_NAME, INVOICE_ALERT_EMAIL, RATE_LIMIT_*, TRUST_PROXY, TOTP_*). See PROJECT-LEVEL.
+- [LOW] (line 12) Specifying exclude replaces Vitest's '**/'-anchored defaults with root-only patterns ('dist/**', 'node_modules/\*\*' don't match nested dirs, and dist-client/cypress/.git defaults are dropped) — currently latent (verified no stray test files outside root node_modules/.claude), but should spread configDefaults.exclude to keep the safety net.
 
-## .claude/hooks/block-env.js
-- Clean — blocks direct `.env` edits via PreToolUse.
+---
 
-## .claude/hooks/format-on-save.js
-- [LOW] Runs `npx prettier --write` but prettier is not a declared devDep and there's no `.prettierrc` (see PROJECT-LEVEL) — formatting is unpinned/non-reproducible.

-
-## src/server.ts
-
-- [x] [LOW] `Function('return import("vite")')()` indirect-eval hack (line 160) to load ESM Vite from the CJS bundle — intentional, brittle. Otherwise clean: plugin order, health check before rate-limit, graceful shutdown.
-
-## src/config/env.ts
-
-- [x] [LOW] Global `Date.prototype.toJSON` override (lines 14-22) — documented PHP-compat gotcha; app-wide. Strong boot-time secret/port validation. Clean.
-
-## src/config/database.ts

-- [x] [MEDIUM] Refresh-token rotation rejects replaced/expired tokens but does NOT revoke the token family on detected reuse (lines 273-280) — no breach containment.
-- [x] [LOW] `loadAuthData` runs on every request (2-3 queries; admin full `permissions.findMany` scan). Strong otherwise (timing-safe, hashed tokens, FOR UPDATE, lockout).
-
-## src/services/ai.service.ts

-- [x] [LOW] `action=project_logs` (line 189) — no ownership check (location path does enforce it); `Number(query.year)` NaN fallbacks.
-
-## src/routes/admin/audit-log.ts
-
-- [x] [MEDIUM] `Number(query.user_id)` (line 33) → NaN → Prisma 500 instead of 400.

-
-## src/routes/admin/invoices-pdf.ts
-
-- [x] [LOW] `JSON.parse(settings.custom_fields)` (451) has no try/catch → malformed JSON makes whole PDF 500; `save=1` raw envelope (1073); loose typing. Note: `notes` IS DOMPurify+cleanQuillHtml sanitized (521).
-
-## src/routes/admin/offers-pdf.ts
-
-- [x] [LOW] `save=1` raw envelope (761); local `cleanQuillHtml` strips only `javascript:` (not data:/vbscript:) — defense-in-depth only (DOMPurify first, 357). Clean.
-
-## src/routes/admin/orders.ts
-
-- [x] [MEDIUM] From-quotation multipart parses `fields.quotationId` with raw `parseInt` (123) not schema/parseId.
-- [x] [LOW] Raw `request.body` casts (203,313); unbounded multipart field/file count (only fileSize limited). Otherwise solid.
-
-## src/routes/admin/orders-pdf.ts
-
-- [x] [HIGH] POST renders an official "Order Confirmation" PDF entirely from client-supplied `body.items` (304-312) — `orders.view` holder can fabricate descriptions/prices not reflecting stored data (downloadable, not persisted → limited impact; trust/authz concern).
-- [x] [LOW] Deprecated `.passthrough()` (30); loose untyped `body.lang`/`applyVat`; `(order as Record).payment_method` cast (387). `notes` sanitized (409).
-
-## src/routes/admin/quotations.ts
-
-- [x] [MEDIUM] GET `/:id` second `quotations.findUnique` for lock info right after `getOffer(id)` (123-129) — redundant query per detail view.
-- [x] [LOW] `(result as any).status` cast (286); empty `catch {}` on NAS PDF delete commented "Non-fatal" but does NOT log (321-323). Lock/heartbeat/unlock scoped to `locked_by=userId` (correct).
-
-## src/routes/admin/received-invoices.ts
-
-- [x] [HIGH] JSON single-create computes `vat_amount=(amount*vat_rate)/100` (394-397) — treats GROSS as net, violating gross-VAT convention and INCONSISTENT with multipart (297) + update (467) paths using `vatFromGross`. Same invoice → different VAT by entry path.
-- [x] [LOW] GET `/` raw envelope (89-93); `stats` `sumCzk` sequential + throws on unknown currency → 500 (135); multipart create loops per-file with no transaction (partial-success on failure).
-
-## src/routes/admin/scope-templates.ts
-
-- [x] [MEDIUM] No `logAudit` on ANY mutation (create/update/delete of scope + item templates) — audit-convention violation.
-- [x] [MEDIUM] DELETE `?action=item&id=X` uses `Number(query.id)` no NaN/existence guard (134-139) → 500; no row-exists/`is_deleted` check.
-- [x] [LOW] `?action=` dispatch mixes two entities in one handler; `Number(body.id)`/`Number(query.id)` instead of validated ids.
-
-## src/routes/admin/plan.ts
-
-- [x] [LOW] `(result.data as any).id`/`(result.oldData as any)` audit casts (256,310,334,361,392,416). Otherwise clean — guards on every route, parseId/parseBody, audit on every mutation, `isAdminLike` reads `roleName`, 92-day range cap.
-
-## src/routes/admin/project-files.ts
-
-- [x] [LOW] Folder-create (120) and move (236) read raw `request.body` bypassing parseBody (manually String-coerced). Path traversal delegated to `resolveProjectPath` (sound). Clean.
-
-## src/routes/admin/projects.ts
-
-- [x] [MEDIUM] GET `/` raw envelope (44-48).
-- [x] [LOW] DELETE reads unvalidated body for `delete_files` (182-183); `(result as any).status` casts; POST `/:id/notes` does NOT `logAudit` though note-delete does (126-148) — inconsistent audit.
-
-## src/routes/admin/roles.ts
-
-- [x] [HIGH] POST `/` no uniqueness guard on `roles.name` and no admin-only gate — a non-admin `settings.roles` holder can create a role (even named `admin`) and attach ANY permission_ids → privilege escalation (59-98). PUT `/:id` can rewrite the `admin` role's permissions (no `name==="admin"` guard like DELETE) → escalation/lockout (102-138).
-- [x] [MEDIUM] Role insert + permission assignment in separate transactions (67-73 vs 76-86) — partial failure leaves orphan role.
-
-## src/routes/admin/sessions.ts
-
-
-## src/routes/admin/totp.ts
-
-- [x] [HIGH] `/enable` verifies the new secret with hardcoded SHA1/6/30 (87-94) not `config.totp.*` — config divergence → enrolled secrets verify under different params than login → lockout.
-- [x] [MEDIUM] `/backup-verify` bcrypt-compares every code, no early-exit on match (307-312) — N bcrypt ops/attempt.
-- [x] [LOW] `/enable` change-flow (2FA on) needs only a live code, not password (65-76); redundant dynamic re-imports shadow `config` (363-370).
-
-## src/routes/admin/trips.ts
-
-- [x] [MEDIUM] GET `/users` (83) guarded only by `requireAuth` — any authenticated user enumerates all active users. Information disclosure.
-- [x] [MEDIUM] GET `/` raw envelope (73-77).
-- [x] [LOW] In-handler permission checks run after parseBody; POST create unconditionally sets `vehicle.actual_km=end_km` (244-247) — can regress odometer (PUT/DELETE recompute via MAX). PUT/DELETE ownership checks correct.
-
-## src/routes/admin/users.ts
-
-- [x] [LOW] Non-admin escalation guard strips `role_id`/`is_active` (109-114, good); bounded `as Parameters<...>` cast (121); forced logout on pwd change not separately audited. Clean (parseId/parseBody/guard/audit, paginated used).
-
-## src/routes/admin/vehicles.ts
-
-- [x] [MEDIUM] GET `/` guarded only by `requireAuth` (15) — any authenticated user lists all vehicles + stats; mutations need `vehicles.manage`. Read should require a view permission. Otherwise clean (single groupBy, delete blocks linked trips).
-
-## src/routes/admin/warehouse.ts
-
-- [x] [HIGH] `confirmIssue` locks only the `sklad_issues` row, not item/batch (service:523) — two different draft issues selecting the same FIFO batch confirm concurrently, both read-modify-write `batch.quantity` -> lost update, negative stock, double-issue. Same gap in `confirmInventorySession`.
-- [x] [HIGH] FIFO batch selection at issue create/update (1496-1499,1622-1625) runs with no lock, persists chosen batch on draft; availability re-checked only at confirm -> wide TOCTOU/oversell.
-- [x] [HIGH] Reports stock-status/project-consumption/movement-log/below-minimum have NO pagination + per-item N+1 (3 sequential aggregates/item; 629-646,2174-2306).
-- [x] [MEDIUM] PUT receipts/issues/inventory-sessions do deleteMany+createMany on lines with NO $transaction (1150-1164,1660-1673,2090-2098) -> failure leaves draft with no lines.
-- [x] [MEDIUM] Attachment save: NAS write then DB insert, no compensating delete (orphan on DB failure); confirm does not verify batch.item_id===line.item_id (wrong item decremented); received_by overwritten at confirm (service:350).
-- [x] [MEDIUM] 2399-line file bundles 8 sub-entities + inline mid-file multipart register (963) — split per sub-entity.
-- [x] [LOW] Unvalidated query.status / Number(query.x) filters; pervasive Record-cast querystrings. Every handler guarded, tiers consistent, attachment DELETE ownership-checked — no missing-guard/IDOR.
-
-## src/services/attendance.service.ts
-
-- [x] [HIGH] `lockUserRow` uses `tx.$executeRaw` for a bare SELECT ... FOR UPDATE (85) — $executeRaw is for write statements; the punch/switch concurrency lock may not reliably hold. Should be `tx.$queryRaw`.
-- [x] [HIGH] `getBalances` N+1: one `leave_balances.findFirst` per user in a loop (491), unbounded.
-- [x] [MEDIUM] `createLeave` books a Dec->Jan range entirely against the start year (getFullYear, 1261); `getStatus` runs 5 independent queries serially.
-- [x] [LOW] `deleteAttendance` (1694) has no ownership param (unlike updateAttendance); hardcoded 160 vacation default x3; ~1700-line file should be split.

-- [x] [LOW] `safeJsonReplacer` duck-types Prisma Decimal via method presence (14-19) — instanceof would be precise. Failure caught+logged. Clean.
-
-## src/services/exchange-rates.ts
-
-- [x] [HIGH] `fetch(url)` (33) has NO timeout/AbortController — a hung CNB endpoint blocks every awaiting caller indefinitely.
-- [x] [MEDIUM] Global single `rateCacheTime` (14,22-24) — a hit on one key refreshes TTL for ALL keys; date-specific entries can outlive TTL; stale-fallback only checks today.
-- [x] [LOW] No validation data.rates is an array before iterating (39).
-
-## src/services/invoice-alerts.ts
-
-- [x] [MEDIUM] Created-invoice alert amount uses only subtotal (net, 92-95) while received invoices show gross — inconsistent; per-invoice `invoice_alert_log.findUnique` N+1 (81,142).
-- [x] [LOW] Dead/identical ternary branches (232-239); sequential unguarded create loop can re-fire alerts; escapeHtml omits the apostrophe char.
-
-## src/services/invoices.service.ts
-
-- [x] [MEDIUM] Three divergent money/VAT implementations: computeInvoiceTotals (47-74), invoiceTotalWithVat (164-196), stats VAT loop (264-270, no per-line rounding) — inconsistent totals risk.
-- [x] [MEDIUM] `getInvoiceStats` serializes many toCzk awaits (247-295) — should Promise.all; createInvoice/updateInvoice take body: Record<string,any> with unchecked `as InvoiceItemInput[]` casts.
-- [x] [LOW] `deleteInvoice` derives year from invoice_number.split("/")[1] (497) -> wrong sequence released for non-standard numbers; getInvoice returns null not {error,status}; paid_date settable on non-paid invoice (463).
-
-## src/services/leave-notification.ts
-
-- [x] [LOW] `formatDate` try/catch ineffective — new Date(invalid) returns Invalid Date, never throws (13-18). Header injection mitigated via sanitizeHeaderValue; send failure logged. Clean.
-
-## src/services/mailer.ts
-
-- [x] [MEDIUM] Transport hardcoded to local sendmail /usr/sbin/sendmail (5-9) — Linux-only, no SMTP fallback; on hosts without the binary every send silently fails (console.error only).
-- [x] [LOW] `to` not validated/sanitized for CRLF (11) — nodemailer guards most.
-
-## src/services/system-settings.ts
-
-- [x] [LOW] JSON.parse of vat-rates/currencies (56,61) no shape validation; process-local cache won't propagate cross-instance within 60s TTL. Two empty catches are commented expected-condition guards (OK). Clean.
-
-## src/services/nas-file-manager.ts
-
-- [x] [MEDIUM] TOCTOU between resolveProjectPath validation (701-713) and the later fs op on the returned path — a symlink swapped into a path component could bypass the guard (low risk on a trusted share); ".." matched as literal substring (679, contained by prefix check).
-- [x] [LOW] createProjectFolder sync/non-atomic (idempotent); MIME gate passes type-less files (SVG served as attachment w/ nosniff -> mitigated); collision suffix loop can yield name_1_2.
-
-## src/services/nas-financials-manager.ts
-
-- [x] [MEDIUM] Fully synchronous fs over a network share on the request path (39-73,81+) — slow/hung NAS blocks the event loop.
-- [x] [LOW] isConfigured() does mkdirSync as a predicate side effect (24); saveIssuedInvoicePdf skips isConfigured() (asymmetry). resolveSafePath guard correct.
-
-## src/services/nas-offers-manager.ts
-
-- [x] [HIGH] Five fully-silent empty-catch blocks, no log/comment (24,46,59,76,111) — violates never-swallow rule; sibling financials manager logs all of them -> failed offer-PDF save/delete is invisible.
-- [x] [LOW] deleteOfferPdf readdir/rmdir swallowed (covered above); isConfigured() mkdir side effect. resolveSafePath correct.
-
-## src/services/numbering.service.ts
-
-- [x] [MEDIUM] getNextSequence first-of-year INSERT race (61-75) -> @@unique([type,year]) P2002 as 500 instead of retry.
-- [x] [MEDIUM] releaseSequence (116-158) SELECT-then-UPDATE with no transaction/lock/tx param — concurrent delete+create can lose a decrement or decrement an in-use number (gap/dup).
-- [x] [LOW] releaseSequence reconstructs highest number from current settings (144-149); changed pattern -> no-op -> gap.
-
-## src/services/offers.service.ts
-
-- [x] [MEDIUM] createOffer TOCTOU: isOfferNumberTaken runs BEFORE the tx (162-167), create inside does not re-check -> concurrent dup numbers (orders.service fixed this).
-- [x] [LOW] deleteOffer never calls deleteOfferPdf -> orphaned PDF on NAS; pervasive any in enrich/list money math.
-
-## src/services/orders.service.ts
-
-- [x] [LOW] enrichOrder/getOrder treat projects as array projects?.[0] (60,151) — confirm cardinality; status->project-status sync duplicated verbatim in both update branches (525-538 & 572-585); deleteOrder FK guard runs outside the tx (599,617-634) -> narrow re-intro window. Tx boundaries otherwise correct.
-
-## src/services/plan.service.ts
-
-- [x] [MEDIUM] N+1 per mutation: resolvePlanLabels(2q)+resolveCategoryLabel(1q) after each write for the audit description (483-489); bulkCreateEntries multiplies it.
-- [x] [LOW] createEntry cap check outside any tx (464) — concurrent creates can exceed cap (intentional per comment). UTC date math deliberate.
-
-## src/services/planCategory.service.ts
-
-- [x] [LOW] slugifyCategory strips a literal combining-marks range (file-byte fragile); uniqueKey unbounded collision loop + race; sort_order=max+1 outside tx (dup possible). Soft-delete-aware checks correct.
-
-## src/services/projects.service.ts
-
-- [x] [LOW] updateProject renames NAS folder after DB commit outside any tx (DB/NAS divergence, failure unlogged at call site, 143); getProject does a synchronous full-base readdirSync on every GET (95); deleteProject removes folder BEFORE the DB delete (218) — inconsistent with orders.service DB-first ordering; Record<string,any> typing.
-
-## src/services/users.service.ts
-
-- [x] [MEDIUM] createUser username/email uniqueness via separate findFirst BEFORE a non-transactional create (116-142) — TOCTOU; duplicate -> unhandled 500 not 409 (updateUser already fixed this in a tx).
-- [x] [LOW] createUser no in-service min password length (updateUser requires >=8); where: any. Last-admin + self-delete guards correct.
-
-## src/services/warehouse.service.ts
-
-- [x] [HIGH] cancelReservation (959-988) has NO row lock and NO transaction — a concurrent confirmIssue fulfilling the same reservation interleaves -> lost fulfillment, double-counted stock. Every other warehouse op locks the parent row; this one was missed.
-- [x] [MEDIUM] selectFifoBatches orders only by received_at no id tie-break (170) + second-truncated precision -> nondeterministic FIFO; getBelowMinimumItems N+1 (232-261).
-- [x] [LOW] validateIssueReservationRules N+1; confirmInventorySession negative-diff decrements item_locations independent of consumed batches (drift); surplus enters at unit_price:0 (valuation); dead itemQty/linePrice locals. Lock/FIFO/storno guards otherwise correct.
-
-## src/schemas/common.ts
-
-- [x] [HIGH] Contains only parseBody — NO shared coercion helpers despite the convention; the z.union number/string transform idiom is re-implemented ~150x across schemas with no shared home. Root cause of the NaN findings below.
-- [x] [LOW] Deprecated ZodSchema import (1); Zod 4 prefers z.ZodType.
-
-## src/schemas/ai.schema.ts
-
-- [x] [LOW] Message objects plain z.object (not strict); AiBudgetSchema.budget_usd no upper bound (39, but Number.isFinite-guarded).
-
-## src/schemas/attendance.schema.ts
-
-- [x] [HIGH] Pervasive unguarded Number(v) transform with NO NaN check on user_id, year, vacation/sick totals, project_id, leave_hours, and all lat/lng/accuracy fields (13-145) — NaN flows to service/Prisma; project_id NaN -> bogus FK.
-- [x] [MEDIUM] Time fields (arrival/departure/break) unbounded z.string() with no HH:MM regex (45-48 etc.).
-- [x] [LOW] Plain z.object not strict; minutes not capped at 59.
-
-## src/schemas/auth.schema.ts
-
-- [x] [MEDIUM] username/password and TOTP password fields have no .max() (4-5) — unbounded string to bcrypt (file caps backup codes for this exact DoS reason but not password).
-- [x] [LOW] totp_code .length(6) but not digits-only; plain objects.
-
-## src/schemas/bank-accounts.schema.ts
-
-- [x] [MEDIUM] iban/bic/account_number/currency/names all unbounded nullish strings (4-9) — no length caps, no IBAN/BIC/ISO format checks.
-- [x] [LOW] position unguarded number-from-form (NaN); plain objects.
-
-## src/schemas/customers.schema.ts
-
-- [x] [MEDIUM] custom_fields: z.array(z.any()) (11,23) — fully over-permissive, arbitrary nested payload persisted as-is.
-- [x] [LOW] All address/id strings unbounded, no format checks; plain objects.
-
-## src/schemas/invoices.schema.ts
-
-- [x] [LOW] quantity/unit_price throw on NaN (good) but vat_rate/position/order_id/customer_id use the UNGUARDED idiom; status/currency/language free strings (no enum); unbounded text; plain objects.
-
-## src/schemas/leave-requests.schema.ts
-
-- [x] [LOW] date_from/date_to min(1) no YYYY-MM-DD regex, no date_to>=date_from cross-check; unbounded notes; plain objects.
-
-## src/schemas/offers.schema.ts
-
-- [x] [LOW] Number coercions correctly refine(!isNaN) but re-implement the idiom ~7x; currency/language free strings; unbounded text; plain objects.
-
-## src/schemas/orders.schema.ts
-
-- [x] [LOW] Same as offers — refined but duplicated idiom; free currency/language; unbounded text; plain objects.
-
-## src/schemas/plan.schema.ts
-
-- [x] [LOW] intFromForm (7-10) is a proper guarded helper but defined locally (belongs in common.ts); project_id coercions (21-102) use the UNGUARDED idiom not intFromForm -> NaN FK; plain objects.
-
-## src/schemas/planCategory.schema.ts
-
-
-## src/schemas/profile.schema.ts
-
-- [x] [MEDIUM] new_password .min(8) no .max() (8); current_password unbounded — unbounded to bcrypt.
-- [x] [LOW] first_name/last_name no min/max; plain objects.
-
-## src/schemas/projects.schema.ts
-
-- [x] [LOW] Create FK fields refine-guard NaN, but Update + quotation_id/order_id use the UNGUARDED idiom (29-44) -> NaN FK on update; status free string (no enum); date strings no regex; plain objects.
-
-## src/schemas/received-invoices.schema.ts
-
-- [x] [HIGH] month/year coerce via Number(v) with NO NaN guard AND no range bounds (5-6,53-60) — month not 1-12, year unbounded; flows into the ledger + date logic.
-- [x] [MEDIUM] amount/vat_rate/vat_amount unguarded idiom (NaN); vat_rate no range bound (negative/>100 accepted) — load-bearing for gross VAT back-calc.
-- [x] [LOW] Unbounded text; plain objects.
-
-## src/schemas/roles.schema.ts
-
-- [x] [LOW] permission_ids: z.array(z.number()) not .int()/positive, no .max() length; name no slug/format; unbounded text; plain objects.
-
-## src/schemas/scope-templates.schema.ts
-
-- [x] [LOW] position/id/default_price unguarded number-from-form (NaN); name/title nullish/optional with no .min(1) (nameless template passes); unbounded text; plain objects.
-
-## src/schemas/settings.schema.ts
-
-- [x] [MEDIUM] Every numeric setting — incl. security-relevant max_login_attempts, lockout_minutes, max_requests_per_minute (15-62) — uses the unguarded idiom with NO NaN guard and NO range bounds; NaN/0/negative can disable lockout/rate-limit.
-- [x] [MEDIUM] custom_fields/supplier_field_order: z.array(z.any()); available_vat_rates no int/range; available_currencies no enum.
-- [x] [LOW] Email-ish fields no .email(); plain objects.
-
-## src/schemas/trips.schema.ts
-
-- [x] [HIGH] start_km/end_km/vehicle_id/user_id use the unguarded idiom — NO NaN check; confirmed routes/admin/trips.ts:226 end_km<start_km guard is bypassed when either is NaN (NaN compare = false) and Number() then writes NaN to Prisma. Real data-integrity bug.
-- [x] [LOW] route_from/route_to unbounded; trip_date no regex; plain objects.
-
-## src/schemas/users.schema.ts
-
-- [x] [MEDIUM] password .min(8) no .max() (6,22-25) — unbounded to bcrypt.
-- [x] [LOW] role_id unguarded NaN; username/names no .max(); plain objects.
-
-## src/schemas/vehicles.schema.ts
-
-- [x] [LOW] initial_km/actual_km unguarded NaN + no .min(0) (negative odometer); spz/name no .max()/plate regex; plain objects.
-
-## src/schemas/warehouse.schema.ts
-
-- [x] [HIGH] All movement quantities/prices (ReceiptItem/IssueItem/InventoryItem/Reservation, 124-219) use the unguarded idiom — NO NaN guard, NO .min/positivity; confirmed these feed stock math in warehouse.service -> NaN/negative corrupt inventory totals.
-- [x] [MEDIUM] All FK coercions (item_id/category_id/supplier_id/project_id/location_id/batch_id/reservation_id) unguarded -> NaN FK to Prisma lookups.
-- [x] [LOW] Supplier email/phone no format check; date strings no regex; unbounded text; plain objects; idiom duplicated dozens of times.
-
-## src/utils/czech-holidays.ts
-
-- [x] [LOW] Easter calc parses YYYY-MM-DD as UTC midnight then reads with local getters (50-57) — correct only because Prague is east of UTC; a negative-offset TZ would be a day early (safe today, fragile). Minor formatting duplication. holidayCache bounded by year.
-
-## src/utils/date.ts
-
-
-## src/utils/encryption.ts
-
-- [x] [MEDIUM] Format detection via split(":").length===3 (27-28) — brittle (a malformed TS value falls through to base64 branch). Crypto sound: random IV per encrypt (no reuse), GCM tag verified, raw 32-byte key. A version/prefix tag would be more robust.
-
-## src/utils/html-to-pdf.ts
-
-- [x] [MEDIUM] process.env.CHROMIUM_PATH || "/usr/bin/chromium-browser" || "/usr/bin/chromium" (21-24) — third path is dead (second operand always truthy); if only chromium exists, launch fails. Browser lifecycle/finally sound (no leak). Injection safety handled upstream.
-
-## src/utils/pagination.ts
-
-- [x] [LOW] sort/search passed through unvalidated (19,22) — trust-boundary note for callers (orderBy field needs an allowlist); page/limit clamping correct.
-
-## src/utils/planAuditDescription.ts
-
-
-## src/utils/totp.ts
-
-- [x] [LOW] console.error logs raw error on decrypt/verify failure (27) — no secret leak; swallow-to-{valid:false} intentional. Correct RFC-6238 (window:1, params from config); replay protection in auth.ts.
-
-## src/types/fastify.d.ts
-
-
-## src/types/index.ts
-
-- [x] [LOW] JwtPayload.role vs AuthData.roleName (51,60) — the documented footgun that invites authData.role==="admin"; no bug here but a hazard.
-
-## prisma/seed.ts
-
-- [x] [MEDIUM] main() unconditionally deleteManys ALL role_permissions + permissions (321-322) before re-inserting — prod-destructive if ever misused (custom roles lose all permissions; stale-reconciliation at 351-368 is dead after the wipe). Dev-only by policy.
-- [x] [LOW] Seeds an admin/admin user hashing the literal "admin" (389) — dev convenience, risk if run on a reachable env.
-
-## scripts/migrate-received-invoices-to-nas.ts
-
-- [x] [LOW] Treats saveReceivedInvoice as sync (41) — verify; sets file_data: null after a claimed-success save with no read-back verification (56) — a 0-byte/corrupt write would lose the only DB copy (one-shot migration).
-
-## scripts/rotate-totp-key.ts
-
-- [x] [HIGH] Hand-rolled decrypt (6-14) only handles the TS iv:enc:tag format; PHP-legacy base64 secrets (no colon) -> Buffer.from(undefined,'hex') throws inside $transaction with no per-user try/catch (58-65) -> the FIRST legacy secret aborts/rolls back the ENTIRE batch. Should reuse src/utils/encryption.ts dual-format decrypt.
-- [x] [LOW] Dry-run shows [FAIL] rows for legacy secrets the real run cannot process — operator must not ignore them.
-
-## prisma/schema.prisma
-
-- [x] [HIGH] Entire sklad\_\* (warehouse) module declares relations with NO explicit onDelete (780-958) — header->line deletes and master-data deletes get engine-default behavior, inconsistent with the explicit cascade/setNull/restrict used everywhere else; define explicit onDelete (Cascade line->header, Restrict line->master-data).
-- [x] [MEDIUM] Warehouse document numbers receipt_number/issue_number/session_number (825,877,935) are nullable and NOT unique — unlike every other document-number column (invoice/order/quotation are @unique); two receipts can share a number.
-- [x] [MEDIUM] invoices.order_id/customer_id, orders.quotation_id/customer_id, quotations.customer_id, project FKs have no explicit onDelete (default Restrict — likely intended but implicit). Several \*\_id are bare Int with no relation/FK -> orphan risk (received_invoices.uploaded_by, quotations.locked_by can point at deleted users).
-- [x] [MEDIUM] sklad_issues.project_id/issued_by, sklad_receipts.supplier_id/received_by, bank_accounts declare no @@index (MySQL auto-indexes the FK constraint, but non-FK hot filters are uncovered and the schema is inconsistent vs the rest).
-- [x] [LOW] Most modified_at/updated_at lack @updatedAt (rely on app code -> stale-timestamp footgun); duplicate identical audit_logs created_at indexes (71,73); is_deleted absent on financial/document models (audit_logs compensates); invoice/order/project/quotation status are free strings not Prisma enums; config lists stored as LongText JSON not Json columns. Money is correctly Decimal throughout (good).
-
-## src/admin/ui/Alert.tsx
-
-- [x] [LOW] MUI close button gets default English aria-label "Close" amid otherwise-Czech UI (18). Clean otherwise.
-
-## src/admin/ui/AppShell.tsx
-
-- [x] [MEDIUM] `setTimeout(()=>logout(),400)` (27) is fire-and-forget, never cleared — fires on an unmounted tree if unmounted within 400ms.
-- [x] [LOW] Decorative inline SVGs lack aria-hidden. Otherwise clean.
-
-## src/admin/ui/Button.tsx
-
-
-## src/admin/ui/Card.tsx
-
-- [x] [MEDIUM] Always wraps children in CardContent with no opt-out/contentProps — edge-to-edge content (media/table) can't use this primitive. Otherwise clean.
-
-## src/admin/ui/Checkbox.tsx
-
-- [x] [MEDIUM] No disabled/name/id/indeterminate/required passthrough — minimal API forces callers to raw MUI. Otherwise clean.
-
-## src/admin/ui/ConfirmDialog.tsx
-
-- [x] [MEDIUM] `cancelText` (and `confirmVariant`) not frozen in `shown` while title/message/confirmText/loading are — cancel label can flicker during the close fade. message is plain string (no XSS). Otherwise clean.
-
-## src/admin/ui/DataTable.tsx
-
-- [x] [MEDIUM] Mobile card branch (78-173) ignores sortBy/sortDir/onSort — sorting controls vanish on phones with no alternative.
-- [x] [LOW] Desktop action cells do NOT stopPropagation (237,254-275) — an action button in an `onRowClick` row fires BOTH (potential double-action; HIGH if any table pairs them). `"actions"` column key magically special-cased (undocumented). Status tints correctly channel-alpha.
-
-## src/admin/ui/DateField.tsx
-
-- [x] [LOW] Dual-label coexistence (picker label + outer Field); parseISO guarded by isValid. Clean.
-
-## src/admin/ui/EmptyState.tsx
-
-- [x] [LOW] icon sized via fontSize:48 — assumes font/SVG-inheriting glyph (an <img> won't scale). Clean.
-
-## src/admin/ui/Field.tsx
-
-- [x] [HIGH] `<Typography component="label">` (24) has NO `htmlFor` and injects no id into children — label not associated with the input (no click-to-focus, screen readers don't announce). System-wide since this is the shared form-label primitive.
-- [x] [MEDIUM] error/hint not linked via aria-describedby and input gets no aria-invalid (41-49). SwitchField lacks disabled passthrough.
-
-## src/admin/ui/FileUpload.tsx
-
-- [x] [LOW] Keys include array index; remove button uses entity glyph with proper aria-label. Clean.
-
-## src/admin/ui/FilterBar.tsx
-
-
-## src/admin/ui/LoadingState.tsx
-
-- [x] [LOW] CircularProgress has no accessible label when `label` omitted (the full-screen AppShell case). Clean otherwise.
-
-## src/admin/ui/Modal.tsx
-
-- [x] [MEDIUM] `cancelText` not frozen in `shown` (cancel label flickers on close); DialogContent renders LIVE children (77) so the form body still flashes its cleared state during the fade — the exact issue the freeze targets, unsolved for the body. Otherwise clean.
-
-## src/admin/ui/MonthField.tsx
-
-- [x] [LOW] ~90% duplicate of DateField.tsx (low-value to consolidate); parseISO guarded. Clean.
-
-## src/admin/ui/MuiProvider.tsx
-
-- [x] [LOW] `defaultMode="dark"` hardcoded (11); verify it agrees with ThemeContext's `data-theme`/`mui-mode` source of truth to avoid a one-frame mismatch. Clean otherwise.
-
-## src/admin/ui/PageEnter.tsx
-
-- [x] [LOW] Children keyed by index (animation only); useReducedMotion called before early return (hook order safe). Clean.
-
-## src/admin/ui/PageHeader.tsx
-
-
-## src/admin/ui/Pagination.tsx
-
-
-## src/admin/ui/ProgressBar.tsx
-
-- [x] [LOW] Determinate LinearProgress has no accessible name (26).
-
-## src/admin/ui/RichText.tsx
-
-
-## src/admin/ui/Select.tsx
-
-- [x] [LOW] `slotProps as {...}` localized sound widening; spread order correct. Clean.
-
-## src/admin/ui/SidebarNav.tsx
-
-- [x] [LOW] Logo onError fallback relies on the fallback existing (no infinite loop). `& svg {width:18}` constraint documented; OdinMark overrides via wrapper + 70% !important (verified). Clean.
-
-## src/admin/ui/StatCard.tsx
-
-
-## src/admin/ui/StatusChip.tsx
-
-
-## src/admin/ui/Tabs.tsx
-
-- [x] [LOW] TabPanel unmounts inactive content with no role="tabpanel"/aria-labelledby wiring (a11y-incomplete).
-
-## src/admin/ui/TextField.tsx
-
-
-## src/admin/ui/ThemeToggle.tsx
-
-
-## src/admin/ui/TimeField.tsx
-
-- [x] [LOW] Module-level REF Date used read-only by date-fns (safe); validates via isValid. Clean.
-
-## src/admin/ui/index.ts
-
-
-## src/admin/ui/navData.tsx
-
-- [x] [LOW] Non-matchPrefix branch uses bare `pathname.startsWith(item.path)` (no boundary) — fragile if a `/x-foo` route is ever added (items needing exactness set end:true). Verbose inline SVG set.
-
-## src/admin/ui/useDialogScrollLock.ts
-
-- [x] [MEDIUM] Module-level lock state — production-safe (balanced [open] dep + cleanup), but a StrictMode/hot-reload double-invoke can transiently skew lockCount.
-- [x] [LOW] Stale comment references removed base.css (now GlobalStyles.tsx).
-
-## src/admin/pages/Warehouse.tsx
-
-- [x] [LOW] Dead/duplicated `MovementRow` type drift (75); redundant per-column `?? 0`; cosmetic isLoading gating. Clean otherwise (read-only).
-
-## src/admin/pages/WarehouseCategories.tsx
-
-- [x] [MEDIUM] `sort_order` via `parseInt(...)||0` no radix (308) — drops a legit 0 and truncates "3.9"->3; convention wants Number/NaN-guard.
-- [x] [LOW] Redundant `saving` state duplicates `submitMutation.isPending`. Broad ["warehouse"] invalidation correct.
-
-## src/admin/pages/WarehouseInventory.tsx
-
-- [x] [MEDIUM] `items` column renders `s.items?.length ?? 0` (125) but list endpoint omits items -> always shows 0; should use a \_count. Otherwise clean.
-
-## src/admin/pages/WarehouseInventoryDetail.tsx
-
-- [x] [HIGH] Rules-of-Hooks: `return <Forbidden/>` (70) precedes `useApiMutation` (72) -> hook-count mismatch crash on permission change.
-- [x] [LOW] `.../0/confirm` URL fallback is dead (handler guards null). Broad invalidation correct.
-
-## src/admin/pages/WarehouseInventoryForm.tsx
-
-- [x] [HIGH] Rules-of-Hooks: `return <Forbidden/>` (83) precedes `useApiMutation` (94).
-- [x] [MEDIUM] `actual_qty` via `Number(e.target.value)` no NaN guard (249) — clearing field -> NaN in payload (receipt/issue forms use parseDecimal). validate() doesn't check qty finite.
-
-## src/admin/pages/WarehouseIssueDetail.tsx
-
-- [x] [HIGH] Rules-of-Hooks: `return <Forbidden/>` (73) precedes useApiMutation (77,89).
-- [x] [MEDIUM] Project link uses raw `<Typography component="a" href>` (316-330) not RouterLink -> full-page reload, breaks SPA nav.
-- [x] [LOW] Dead `/0/` URL fallbacks.
-
-## src/admin/pages/WarehouseIssueForm.tsx
-
-- [x] [HIGH] Rules-of-Hooks: `return <Forbidden/>` (267) precedes useApiMutation/useState (335,347).
-- [x] [MEDIUM] `confirmIssue` setState(id) then immediately `await mutateAsync`; the url: closure reads pre-update id -> first confirm hits `/0/confirm`. Pass id as mutation variable.
-- [x] [LOW] Form-seeding effects (238,242) are effect-as-derived-state.
-
-## src/admin/pages/WarehouseIssues.tsx
-
-
-## src/admin/pages/WarehouseItemDetail.tsx
-
-- [x] [HIGH] Rules-of-Hooks: `return <Forbidden/>` (157) precedes useApiMutation (164,180).
-- [x] [MEDIUM] Error-handling effect navigates away (148-153) — effect-as-control-flow (could be a render branch).
-- [x] [LOW] Form-seed logic duplicated 3x (128/132/248-261); `useModalLock(editing)` (155) locks page scroll for an in-page (non-modal) edit form — likely unintended.
-
-## src/admin/pages/WarehouseItems.tsx
-
-
-## src/admin/pages/WarehouseLocations.tsx
-
-- [x] [LOW] toggleMutation toasts in handler not onSuccess (inconsistent); dead czechPlural ternary. Guard correctly after hooks. Clean otherwise.
-

-
-- [x] [HIGH] Rules-of-Hooks: `return <Forbidden/>` (97) precedes useApiMutation (101,113,126).

-- [x] [HIGH] Rules-of-Hooks: `return <Forbidden/>` (203) precedes useApiMutation/useState (269,281).
-- [x] [MEDIUM] Same stale-closure confirm bug as IssueForm (307-309) -> `/0/confirm` on first confirm.
-- [x] [LOW] Uses imperative document.createElement input + hand-rolled dropzone instead of kit FileUpload (620-633).
-
-## src/admin/pages/WarehouseReceipts.tsx
-
-
-## src/admin/pages/WarehouseReports.tsx
-
-- [x] [MEDIUM] Project-consumption & movement-log tabs fetch via raw apiFetch + useState (263-290,386-413) not React Query — results NOT in ["warehouse"] cache, won't refresh on mutations; existing query options unused.
-- [x] [LOW] Duplicated MovementLogRow type (46); empty `catch {}` -> setData([]) swallows fetch errors (285,408); raw `row.date` not formatDate'd (426).
-
-## src/admin/pages/WarehouseReservations.tsx
-
-- [x] [MEDIUM] Create & cancel use raw apiFetch + manual invalidate (170-217) not useApiMutation (broad key correct, but plumbing duplicated).
-- [x] [LOW] Empty catches don't log; `quantity` via Number() no NaN guard (457) and `NaN<=0` is false so NaN can be submitted.
-
-## src/admin/pages/WarehouseSuppliers.tsx
-
-- [x] [MEDIUM] `toggleActive` setState(id) then immediate `await mutateAsync` — url: closure reads null id -> PUT hits the collection root (wrong endpoint) on first toggle. Pass id as mutation variable.
-- [x] [LOW] Redundant `saving` state. Guard correctly after hooks. Clean otherwise.
-
-## src/admin/pages/Attendance.tsx
-
-- [x] [MEDIUM] `calculateBusinessDays` parses YYYY-MM-DD via `new Date()` (UTC midnight) + local `getDay()` (480-488) — can mis-count business days in the evening Prague window.
-- [x] [LOW] leaveRequestMutation invalidates attendance/leave-requests/users but NOT ["leave"] (303) — approver's pending queue (["leave","pending"]) won't auto-refresh; live clock (676) never ticks; notes synced via effect can clobber unsaved edits (336-340). todayLocalStr used (good).
-
-## src/admin/pages/AttendanceAdmin.tsx
-
-
-## src/admin/pages/AttendanceBalances.tsx
-
-- [x] [HIGH] Rules-of-Hooks: `return <Forbidden/>` (171) precedes useApiMutation (173,189).
-- [x] [LOW] parseFloat on vacation/sick fields -> NaN on empty (770,781,794) into payload.
-
-## src/admin/pages/AttendanceCreate.tsx
-
-- [x] [LOW] `leave_hours: parseFloat()` -> NaN on cleared field (190). todayLocalStr used; broad invalidation. Clean otherwise.
-
-## src/admin/pages/AttendanceHistory.tsx
-
-- [x] [MEDIUM] ~865-line file with inline print-HTML template + hidden print JSX — split candidate.
-- [x] [LOW] Duplicates holiday/business-day logic that also exists in attendanceHelpers (84-149). normalizeDateStr used; hooks before guard. Clean otherwise.
-
-## src/admin/pages/AttendanceLocation.tsx
-
-- [x] [LOW] Dead LoadingState branch (199 unreachable, `!record` returns null at 187 while pending). Popup via createElement/textContent (no XSS); Leaflet cleanup correct. Clean.
-
-## src/admin/pages/AuditLog.tsx
-
-- [x] [HIGH] Rules-of-Hooks: `return <Forbidden/>` (185-187) precedes useApiMutation (189).
-
-## src/admin/pages/CompanySettings.tsx
-
-- [x] [MEDIUM] ~1503-line file — split candidate (info/banking/numbering/currency-VAT/logo cards).
-- [x] [MEDIUM] Uses deprecated MUI `inputProps` (1312) — silently ignored in v7 so min/step not applied (rest of file uses slotProps.htmlInput).
-- [x] [LOW] Doesn't wrap in PageEnter (raw motion.div per card — intentional embedded mode); fieldOrder index logic fragile. Blob cleanup correct.
-
-## src/admin/pages/Dashboard.tsx
-
-- [x] [LOW] DashData hand-rolled with `[key]:unknown` index sig + `as DashData` cast (76,88) bypasses query typing; 2FA handlers use raw apiFetch + manual invalidate (179-211) not useApiMutation. getCzechDate used (good); gated sections. Clean otherwise.
-
-## src/admin/pages/InvoiceDetail.tsx
-
-- [x] [MEDIUM] ~2243-line file — split candidate (SortableInvoiceRow / paid read-only view / create-edit form).
-- [x] [MEDIUM] UTC anti-pattern `new Date(...).toISOString().split("T")[0]` for due_date default (494), issue/due/tax dates (645-651) and computedDueDate (818-823) — the latter reaches the saved payload (977), persisting a day-early due date in evening Prague.
-- [x] [LOW] Editable `notes` state never wired to an input in non-paid mode (only form.notes saved) — confirm intended. DOMPurify correctly applied before the one dangerouslySetInnerHTML (1562) — no XSS. Money math guarded; blob cleanup correct.
-
-## src/admin/pages/Invoices.tsx
-
-- [x] [LOW] handleDelete/toggleStatus/handlePdf use raw apiFetch + manual invalidate (broad keys, correct behavior, off-convention); overdue rowSx UTC-vs-local compare off by a day near midnight (506-507, visual only). Clean otherwise.
-
-## src/admin/pages/LeaveApproval.tsx
-
-- [x] [HIGH] Rules-of-Hooks: `return <Forbidden/>` (158) precedes useApiMutation (160,173).
-
-## src/admin/pages/LeaveRequests.tsx
-
-
-## src/admin/pages/Login.tsx
-
-- [x] [LOW] `verify2FA(loginToken!, ...)` non-null assertion (105) — a null token (server returns requires2FA w/o token) would pass `null!`. Otherwise secure: tokens via useAuth, no persisted token state, TOTP input strips non-digits, autoComplete=one-time-code, renders outside AppShell.
-
-## src/admin/pages/NotFound.tsx
-
-
-## src/admin/pages/Odin.tsx
-
-
-## src/admin/pages/OfferDetail.tsx
-
-- [x] [HIGH] Heartbeat effect (730) deps omit `isCompleted` though the guard reads it (731) — lock heartbeat keeps running after transition to dokoncena (stale closure).
-- [x] [MEDIUM] ~2059-line file — split candidate (SortableItemRow / scope-sections / draft logic).
-- [x] [LOW] `payload: any` (884) and item-update casts; parseInt/parseFloat on qty/price yield NaN on cleared field (rendered until totals guard). Broad invalidation correct; draft parse guarded; blob revoked.
-
-## src/admin/pages/Offers.tsx
-
-- [x] [LOW] Expired check uses idiosyncratic `new Date(new Date().toDateString())` (658, functional). Otherwise clean (broad keys, kit, blob revoke, keys).
-
-## src/admin/pages/OffersCustomers.tsx
-
-- [x] [LOW] parseInt without radix on `key.split("_")[1]` (239,259,675, harmless decimal). Otherwise clean (custom-field re-key correct, broad invalidation, a11y).
-
-## src/admin/pages/OffersTemplates.tsx
-
-- [x] [LOW] openEdit fetches via raw apiFetch (bypasses RQ cache) for on-demand modal. Guard is before a hooks-free body (no violation). Otherwise clean.
-
-## src/admin/pages/OrderDetail.tsx
-
-- [x] [CRITICAL] Rules-of-Hooks: 3 useApiMutation (181,187,193) AFTER `return <Forbidden/>` (179) — crash when orders.view absent / permission flips.
-- [x] [LOW] `valid_transitions?.filter(...).length! > 0` (466) misleading non-null assertion. Section rich text DOMPurify-sanitized before dangerouslySetInnerHTML (760) — no XSS. Broad invalidation; blob cleanup.
-
-## src/admin/pages/Orders.tsx
-
-- [x] [LOW] vat_rate sent as raw string in JSON create (272, relies on Zod coercion). Otherwise clean — Forbidden return (312) after all hooks; broad invalidation; keys.
-
-## src/admin/pages/PlanWork.tsx
-
-- [x] [LOW] Several mutation callbacks use `body: any`/`data: any` (185,395,412,476,491). `isoDate` toISOString().slice(0,10) is correct (Plan UTC convention, not a finding). Forbidden return after hooks; pulse timer cleaned; todayIsoLocal used. Clean otherwise.
-
-## src/admin/pages/ProjectDetail.tsx
-
-- [x] [CRITICAL] Rules-of-Hooks: 4 useApiMutation (179,194,203,209) AFTER `return <Forbidden/>` (177).
-- [x] [LOW] formatNoteDate duplicates utils/formatters date logic. Broad invalidation (projects/warehouse); keys.
-
-## src/admin/pages/Projects.tsx
-
-- [x] [LOW] List query uses raw `search` not debounced (219) — every keystroke refetches (Offers/Orders debounce). Hooks (useApiMutation 124,173) precede the guard (222) — correct ordering. Broad invalidation; keys.
-
-## src/admin/pages/ReceivedInvoices.tsx
-
-- [x] [MEDIUM] `toDateInput` uses `toISOString().split("T")[0]` (453) to seed edit-form dates — forbidden UTC-split (day-early evening Prague). Use normalizeDateStr.
-- [x] [MEDIUM] ~1237-line file — split candidate (upload modal + edit modal).
-- [x] [LOW] Render-phase ref mutation `hasLoadedOnce.current=true` (279); loose parseFloat typing (557). VAT-from-gross preserved; broad invalidation; blob cleanup.
-
-## src/admin/pages/Settings.tsx
-
-- [x] [HIGH] Rules-of-Hooks: 5 useApiMutation (319,339,354,372,390) AFTER `return <Navigate/>` (315) — useQuery/useMemo/useState are above, mutations are not.
-- [x] [MEDIUM] ~1354-line file — split candidate (roles / system-settings / system-info).
-- [x] [LOW] `systemInfo as Record<string,any>` (679); O(n^2 log n) permission-group sort (1243, negligible). Tab state derived from URL (good); broad invalidation.
-
-## src/admin/pages/Trips.tsx
-
-- [x] [HIGH] Rules-of-Hooks: 2 useApiMutation (190,204) AFTER `return <Forbidden/>` (188).
-- [x] [LOW] Dead `[,setLastKm]` state (186, only setter used); parseInt without radix (287,315-316). todayLocalStr used; broad invalidation (trips/vehicles); keys.
-
-## src/admin/pages/TripsAdmin.tsx
-
-- [x] [HIGH] Rules-of-Hooks: 2 useApiMutation (236,255) AFTER `return <Forbidden/>` (231).
-- [x] [LOW] handlePrint uses raw printWindow.document.write of app data (344-417) — low XSS surface (React-escaped innerHTML) but fragile; iframe/template safer. Broad invalidation; keys.
-
-## src/admin/pages/TripsHistory.tsx
-
-- [x] [LOW] `totals` computed before the Forbidden return (wasteful when unauthorized) — but all hooks precede the return (no violation). Read-only; kit; keys. Clean.
-
-## src/admin/pages/UiKit.tsx
-
-
-## src/admin/pages/Users.tsx
-
-- [x] [HIGH] Rules-of-Hooks: 3 useApiMutation (126,152,162) AFTER `return <Forbidden/>` (173).
-- [x] [LOW] `roles[0]?.id ? ... : ""` default would skip a role id of 0 (never 0 in practice). Shared broad USER_INVALIDATE array (good); self-deactivation guarded; keys.
-
-## src/admin/pages/Vehicles.tsx
-
-- [x] [HIGH] Rules-of-Hooks: 3 useApiMutation (121,136,146) AFTER `return <Forbidden/>` (162).
-- [x] [LOW] Raw MUI `<Chip>` instead of kit StatusChip (264); `select: data as unknown as Vehicle[]` double-cast (100); parseInt without radix (404). Broad invalidation (vehicles/trips); rowInactive; keys.
-
-## src/admin/components/AlertContainer.tsx
-
-- [x] [LOW] Stacking offset keyed off array index (15) — removing a middle alert reflows/can overlap with 3+ alerts. Keys use alert.id. Otherwise clean.
-
-## src/admin/components/AttendanceShiftTable.tsx
-
-- [x] [LOW] Project-cell key falls back to index when log.id nullish (119); duration math not memoized. Otherwise clean (no any, keys, no effects).
-
-## src/admin/components/BulkAttendanceModal.tsx
-
-- [x] [LOW] Select-all label shows "Odznacit vse" when users empty (BulkPlanModal guards this — inconsistent). Otherwise clean.
-
-## src/admin/components/BulkPlanModal.tsx
-
-
-## src/admin/components/ErrorBoundary.tsx
-
-- [x] [LOW] componentDidCatch only console.errors (22) — no telemetry hook. Correct boundary pattern otherwise.
-
-## src/admin/components/Forbidden.tsx
-
-
-## src/admin/components/OrderConfirmationModal.tsx
-
-- [x] [MEDIUM] Local state (step/items/applyVat/lang) never reset on reopen — component is permanently mounted, toggled by isOpen; reopening shows prior step/edits and items captured once via useState(initialItems) go stale.
-- [x] [MEDIUM] `finally` closes the modal even when onGenerate throws (58-77) — a generation error drops edited items with only a transient toast.
-- [x] [LOW] Editable rows key={i} — deleting a non-last row shifts indices (focus jumps; data stays correct since controlled).
-
-## src/admin/components/PlanCategoriesModal.tsx
-
-- [x] [LOW] Label TextField uncontrolled defaultValue with no key={c.label} (148) — won't re-seed on external rename (color input does add key); inline delete-confirm instead of kit ConfirmDialog. Broad ["plan","dashboard","audit-log"] invalidation correct; onBlur-commit.
-
-## src/admin/components/PlanCellModal.tsx
-
-- [x] [MEDIUM] Props onSaveEntry/onUpdateEntry/onSaveOverride/onUpdateOverride typed `any` (77-82) — untyped save payloads on the most bug-prone path.
-- [x] [LOW] EditForm derives state from `initial` via useState (201-206) relying on parent remount per record (no key reset — fragile if parent swaps entryId same-kind); odd Czech phrasing (415). Discriminated-union mode + kit otherwise strong.
-
-## src/admin/components/PlanGrid.tsx
-
-- [x] [LOW] `projects.find(...)` inside per-cell render loop (612-616) O(days*users*cells\*projects) — build a useMemo Map (rarely hit since server embeds label); eachDay/days recomputed every render (not memoized). todayIso uses local Y/M/D (correct); thorough aria-labels.
-
-## src/admin/components/PlanRangeChips.tsx
-
-- [x] [LOW] `readonly` prop accepted then discarded via `void readonly` (17) — dead prop (PlanGrid still passes it). className styling intentional (classes defined in PlanGrid root). Otherwise clean.
-
-## src/admin/components/ProjectFileManager.tsx
-
-- [x] [MEDIUM] Drag-over has no drag-depth counter — handleDragLeave (377-380) fires on every child boundary -> drop overlay flickers during drag.
-- [x] [MEDIUM] File ops use raw apiFetch + manual invalidate of sub-key `["projects",id,"files"]` (349-351) not broad ["projects"] (deliberate scope, documented deviation).
-- [x] [LOW] `catch {}` substitutes a generic toast but never logs the real error (336,408,438,471,508); sequential per-file upload; breadcrumb join breaks if a folder name contains "/". Escape/Enter handling + canManage gating correct.
-
-## src/admin/components/RichEditor.tsx
-
-- [x] [LOW] `_delta: any` on the Quill onChange param (91, react-quill-new loose types — could be unknown); useLayoutEffect font-set no-ops if ref not ready (mounts sync in practice). Never injects HTML — consumers DOMPurify-sanitize. No XSS.
-
-## src/admin/components/ShiftFormModal.tsx
-
-- [x] [MEDIUM] `leave_hours` via parseFloat (330-331) writes NaN to form state on empty input — serializes to invalid; should fall back to 0 like the Number(...)||0 pattern.
-- [x] [LOW] Module-level mutable `_logKeyCounter` (20) shared across instances (fragile under StrictMode/concurrent instances) — use a per-instance ref/randomUUID; server-loaded logs may lack \_key -> index-key risk. Derived isWorkType/isCreate + kit otherwise correct.
-
-## src/admin/components/ShortcutsHelp.tsx
-
-- [x] [LOW] Entire component is `return null` — dead stub; remove the file + references, or wire it up.
-
-## src/admin/components/dashboard/DashActivityFeed.tsx
-
-
-## src/admin/components/dashboard/DashAttendanceToday.tsx
-
-- [x] [LOW] Key `${u.user_id}-${i}` index-suffixed (75); user_id alone is unique. Clean.
-
-## src/admin/components/dashboard/DashKpiCards.tsx
-
-- [x] [LOW] buildKpiCards recomputed every render (124, cheap); framer-motion entrance has no reduced-motion branch (JS-driven animate not stopped by the GlobalStyles CSS reset) — applies to DashQuickActions/DashProfile/DashSessions too. Clean otherwise.
-
-## src/admin/components/dashboard/DashProfile.tsx
-
-- [x] [MEDIUM] handleSubmit (175-197) uses raw apiFetch and invalidates NO React Query domain after a profile PUT — anything keyed on user data goes stale.
-- [x] [LOW] `delete (dataToSave as any).current_password` casts (172-173); magic 300ms sleep before success toast (189); no reduced-motion branch.
-
-## src/admin/components/dashboard/DashQuickActions.tsx
-
-- [x] [HIGH] handleTripSubmit (157-176) POSTs a trip via raw apiFetch and NEVER invalidates ["trips"]/["dashboard"] (no useQueryClient imported) — list/dashboard stay stale until manual refetch.
-- [x] [MEDIUM] `result` from .json() untyped any (96,116,164); last_km assigned into a string field with no String() coercion.
-- [x] [LOW] Empty catches don't log (104-106,120-122); parseInt without radix. tripDistance derived (good); todayLocalStr used.
-
-## src/admin/components/dashboard/DashSessions.tsx
-
-- [x] [LOW] Correctly invalidates ["sessions"]; shared `deleting` flag (one dialog at a time); no reduced-motion branch. Clean.
-
-## src/admin/components/dashboard/DashTodayPlan.tsx
-
-- [x] [LOW] key={i} on plans (96, tiny static list); color-mix bgcolor (43, modern-browser only). Clean.
-
-## src/admin/components/odin/InvoiceReviewCard.tsx
-
-
-## src/admin/components/odin/OdinChat.tsx
-
-- [x] [LOW] saveInvoice invalidates ["invoices"] (353) — broad key DOES cover received invoices (keyed ["invoices","received"]), so correct; persist() is fire-and-forget (failure only console.error, user not told history unsaved). Seed/auto-scroll effects are legitimate. Invoice-only guard correct.
-
-## src/admin/components/odin/OdinComposer.tsx
-
-- [x] [LOW] `fileRef as RefObject<HTMLInputElement>` unnecessary cast (48); Enter-to-send calls onSubmit even when !canSubmit (parent re-guards — no double-send). Clean.
-
-## src/admin/components/odin/OdinMark.tsx
-
-
-## src/admin/components/odin/OdinSidebar.tsx
-
-- [x] [LOW] Conversation row is a clickable <Box onClick> (128) — not a button/no role/tabIndex, so not keyboard-focusable (a11y gap); kebab has aria-label. Clean otherwise.
-
-## src/admin/components/odin/OdinThread.tsx
-
-- [x] [LOW] Bubble key={i} (174, append-only so stable); content via Typography pre-wrap (no XSS); reduced-motion gated. Clean.
-
-## src/admin/components/odin/types.ts
-
-
-## src/admin/components/warehouse/ItemPicker.tsx
-
-- [x] [MEDIUM] useQuery(warehouseItemListOptions({search: inputValue})) fires on EVERY keystroke with no debounce (30-32) — request spam; useDebounce hook exists. renderOption correctly extracts key (good).
-
-## src/admin/components/warehouse/ReservationPicker.tsx
-
-- [x] [MEDIUM] On item/project change, if the selected `value` is no longer in `reservations`, the component doesn't reset/notify the parent — parent can hold a stale reservationId. Redundant Number() casts (41,49). Typed (no any).
-
-## src/admin/AdminApp.tsx
-
-- [x] [LOW] No RequireAuth wrapper visible in the router — auth gating delegated to AppShell/pages (a new top-level route outside AppShell would be public by default); Dashboard eagerly imported (not lazy) (13). Clean otherwise.
-
-## src/admin/GlobalStyles.tsx
-
-
-## src/admin/theme.ts
-
-- [x] [LOW] containedPrimary hover/active transform lacks a prefers-reduced-motion guard present on MuiButton.root/MuiOutlinedInput (89-95); iconBadgeSx key cast loses type-safety (248, behavior fine). Clean otherwise.
-
-## src/admin/theme.test.ts
-
-- [x] [LOW] Heavy `as any`/`as unknown as ...` to reach theme internals (deliberate test shortcut). Clean.
-
-## src/App.tsx
-
-- [x] [LOW] AdminLoader reads data-theme once at render — dark fallback on cold load before ThemeContext sets it (acceptable). Clean otherwise.
-
-## src/main.tsx
-
-
-## src/vite-env.d.ts
-
-
-## src/context/ThemeContext.tsx
-
-- [x] [MEDIUM] Theme single-source is correct (mui-mode only; legacy boha-theme read-once-then-deleted) BUT the "dark" default is hardcoded twice (here:30 and MuiProvider.tsx:11) — change one without the other and page (MUI) vs toggle desync on first paint; reconcile to one constant.
-- [x] [LOW] No `storage` event listener — two tabs won't sync theme until reload. View-Transition/flushSync + reduced-motion fallback correct.
-
-## src/admin/context/AlertContext.tsx
-
-
-## src/admin/context/AuthContext.tsx
-
-- [x] [MEDIUM] `apiRequest` (318-350) duplicates the refresh+retry logic of utils/api.ts apiFetch — two parallel 401-retry paths with DIVERGENT behavior (apiRequest ignores abort signals and doesn't set the session-expired flag). Consolidate onto apiFetch.
-- [x] [MEDIUM] Proactive-refresh timer fires a closure-captured `silentRefresh` (memoized [] + eslint-disable, 117-125); works only because everything is read through refs — fragile cyclic setup.
-- [x] [LOW] In-flight refresh not cancelled on logout (a resolving refresh could re-setUser); checkSession maps user twice (181-182). Token held in-memory only (secure). Dedup + expires_in proactive refresh otherwise correct.
-
-## src/admin/utils/api.ts
-
-- [x] [LOW] Module-singleton `state` with injected getTokenFn/refreshFn couples a module global to React lifecycle (resetApiState for tests); on a 401 with aborted signal returns the 401 response not the 499 sentinel used elsewhere (inconsistent); its refreshPromise dedup is a second single-flight layer alongside AuthContext's. Up-front refresh/abort/FormData handling correct.
-
-## src/admin/utils/attendanceHelpers.ts
-
-- [x] [MEDIUM] getTimePart (105-109) uses `new Date(datetime).getHours()` (TZ-dependent) while sibling extractTime parses the string to avoid TZ conversion — can yield a different hour than displayed at DST/offset edges, violating the file's own stated ethos.
-- [x] [LOW] getLeaveTypeBadgeClass returns badge-\* classes that exist only in AttendanceHistory's print <style> (near-dead as a general helper); calculateNightMinutes mixes timestamp windows with local-midnight math (Prague-TZ-coupled).
-
-## src/admin/utils/dashboardHelpers.ts
-
-- [x] [MEDIUM] STATUS_DOT_CLASS (7-12) is exported but referenced by ZERO files and maps to dash-status-\* CSS classes removed in the MUI migration — dead code.
-- [x] [LOW] getCzechDate ISO-week calc (59-62) is the naive formula (off-by-one near year boundaries, display-only). Other exports live/correct.
-
-## src/admin/utils/formatters.ts
-
-
-## src/admin/hooks/useAttendanceAdmin.ts
-
-- [x] [HIGH] ~1402-line file mixing the React hook, computeUserTotals payroll math, and ~370 lines of print-HTML templating — the two pure modules have no React dep and should be extracted to utils/ for testability.
-- [x] [HIGH] Does data fetching with useEffect+useState+manual setLoading (818-922) against the "React Query for fetching" convention, AND also invalidateQueries(["attendance"]) after mutations — two sources of truth (its own fetchData cache vs the ["attendance"] domain).
-- [x] [MEDIUM] fetchData useCallback closes over `alert` (captured first render) with eslint-disable + initialLoadDone ref; pervasive Record<string,any>/any in print/payroll helpers (350,380,597,1319); 300ms sleeps before success toasts as a sync crutch.
-- [x] [LOW] handlePrint document.write of escaped data; today/now recomputed every render.
-
-## src/admin/hooks/useDebounce.ts
-
-
-## src/admin/hooks/useModalLock.ts
-
-- [x] [LOW] Module-level activeLocks counter locks only document.body.style.overflow (3-7) — CLAUDE.md says dialogs must lock <html> (via useDialogScrollLock) because html{overflow-x:hidden} makes <html> the scroller; this body-only lock likely doesn't prevent background scroll for the app layout (superseded/near-dead — confirm callers).
-
-## src/admin/hooks/usePaginatedQuery.ts
-
-- [x] [LOW] `options: any` param (24, eslint-disable) loses generic typing; `as UseQueryOptions<...>` unchecked. Clean otherwise.
-
-## src/admin/hooks/usePlanWork.ts
-
-- [x] [MEDIUM] Optimistic rollback stashed via `(createEntry as any)._rolled = rolled` (264,332,369,403,454,481) — mutating the TanStack mutation object is non-idiomatic and NOT concurrency-safe (two in-flight mutations overwrite each other's \_rolled → wrong-snapshot rollback). Use onMutate context.
-- [x] [MEDIUM] Heavy any on mutationFn/onSuccess (237,243,379,385,491); gridQuery.queryFn does r.json() with no res.ok check (92-94) — treats an error body as undefined data.
-- [x] [LOW] isoDate UTC slice is correct for Plan, but anchor seeded from a LOCAL `new Date()` then read with getUTC\* (27-31,70,80-86) — verify the late-evening Prague window doesn't shift the week/month anchor. keepPreviousData + broad invalidation correct.
-
-## src/admin/hooks/useReducedMotion.ts
-
-- [x] [LOW] setReduced(false) initial then reconciles in effect — one render with motion for reduced-motion users (documented intentional; a lazy matchMedia initializer would avoid the flash). Listener add/remove correct.
-
-## src/admin/hooks/useTableSort.ts
-
-
-## src/admin/lib/apiAdapter.ts
-
-- [x] [LOW] paginatedJsonQuery fallback uses per_page=items.length, total_pages=1 when server omits pagination (74-80) — masks a missing-meta bug; `result.data as T`/`items as T[]` unchecked (by design). 401/success/error handling correct.
-
-## src/admin/lib/entityTypeLabels.ts
-
-
-## src/admin/lib/queryClient.ts
-
-
-## src/admin/lib/queries/ai.ts
-
-- [x] [LOW] Singular/plural key split: list ["ai","conversations"] vs messages ["ai","conversation",id,"messages"] — a broad ["ai","conversations"] invalidation won't touch open threads (intended; relies on staleTime Infinity/gcTime 0 to refetch on mount). Correct.
-
-## src/admin/lib/queries/attendance.ts
-
-- [x] [MEDIUM] attendanceLocationOptions (166-185) bypasses jsonQuery: reads `result.data.record||result.data` from untyped `response.json()` with NO response.ok/401 guard — a 500/non-JSON throws an opaque error instead of the adapter's normalized one.
-- [x] [LOW] historyOptions hardcodes limit=1000 in the queryFn (not in the key). Keys unique per action/year; enabled:!!id correct.
-
-## src/admin/lib/queries/auditLog.ts
-
-- [x] [LOW] queryFn returns Record<string,unknown>[] rows (23-26) — untyped; consumers cast to AuditLogEntry[] at the page. Key ["audit-log",filters] consistent with broad invalidation.
-
-## src/admin/lib/queries/common.ts
-
-
-## src/admin/lib/queries/dashboard.ts
-
-- [x] [MEDIUM] sessionsOptions (27-38) hand-rolls fetch with untyped json() and no response.ok/401 guard before reading data.success — inconsistent with jsonQuery.
-- [x] [LOW] dashboardOptions returns Record<string,unknown> (untyped payload). Keys broad/unique.
-
-## src/admin/lib/queries/invoices.ts
-
-- [x] [LOW] receivedInvoiceListOptions (157-169) manually lists filter fields into the key instead of spreading filters — a new filter silently won't bust the cache (inconsistent with invoiceListOptions); ["invoices",id] shares prefix with list/stats/received (no real collision). NOTE: received invoices ARE under ["invoices","received"], so a broad ["invoices"] invalidation covers them.
-
-## src/admin/lib/queries/leave.ts
-
-- [x] [LOW] Two key families for one entity: ["leave-requests","mine"/"all"] vs ["leave","pending"/"processed"] — mutations invalidate both domains (consistent) but it's avoidable duplication that's easy to under-invalidate later; rows typed Record<string,unknown> despite a LeaveRequest interface in-file.
-
-## src/admin/lib/queries/mutations.ts
-
-- [x] [LOW] invalidate() loops single top-level string keys (100-104) — can't express a multi-segment broad key (fine for current usage); onSuccess user override force-cast hides signature mismatch. ApiError.status/401 sentinel/broad-invalidation default correct.
-
-## src/admin/lib/queries/offers.ts
-
-- [x] [LOW] offerListOptions (90) omits the <T> on paginatedJsonQuery → rows are `unknown` (the only list option missing its generic); retry:false on detail justified/documented.
-
-## src/admin/lib/queries/orders.ts
-
-- [x] [LOW] orderListOptions (75) also omits <T> → unknown rows; same theoretical id-vs-literal key note.
-
-## src/admin/lib/queries/plan.ts
-
-
-## src/admin/lib/queries/projects.ts
-
-- [x] [LOW] projectFilesOptions treats HTTP 404 as empty result (97-99, reasonable but undocumented divergence from jsonQuery). Keys safe.
-
-## src/admin/lib/queries/settings.ts
-
-
-## src/admin/lib/queries/trips.ts
-
-- [x] [LOW] tripListOptions and tripHistoryOptions hit the SAME endpoint under two key families (redundant cache); tripVehiclesOptions duplicates vehicleListOptions (same /vehicles endpoint cached twice — both invalidated correctly, verified). Redundant footprint only.
-
-## src/admin/lib/queries/users.ts
-
-- [x] [LOW] userListOptions key ["users",{permission}] fans out cache per-permission (a ["users"] mutation invalidates all via prefix — fine). Clean otherwise.
-
-## src/admin/lib/queries/vehicles.ts
-
-- [x] [LOW] Returns Record<string,unknown>[] (untyped; consumers cast). Broad ["vehicles"] key invalidated correctly.
-
-## src/admin/lib/queries/warehouse.ts
-
-- [x] [LOW] Detail keys ["warehouse",entity,id] share prefix with list (no collision); locationListOptions defaults filters in two places that must stay in sync (251-253); undefined filter segments in stock-status/movement-log keys. Every mutation invalidates broad ["warehouse"] (verified).
-
-## src/__tests__/ai.test.ts
-
-- [x] [MEDIUM] Budget-block test inserts cost_usd=budget+1 cleaned only in afterAll — inflates getMonthSpendUsd for other current-month tests in the file (order-safe today, fragile); "sums only current month" asserts spend<6 relying on no other current-month rows.
-- [x] [LOW] Configured chat path + the text-only canned-reply guard are untested (avoids API spend — acceptable); duplicated buildApp/token helpers; ai.use grant migration not exercised (relies on admin bypass).
-
-## src/__tests__/auth.service.test.ts
-
-- [x] [HIGH] Only failure/null branches of verifyAccessToken tested — the happy path (valid token → loadAuthData → AuthData) has ZERO coverage.
-- [x] [LOW] hashToken tests don't pin a known vector (a silent algo change staying 64-hex deterministic would pass).
-
-## src/__tests__/auth.test.ts
-
-- [x] [HIGH] No successful-login test — the whole happy path (tokens issued, refresh cookie set, 2FA loginToken branch) untested; only 401/400 negatives.
-- [x] [MEDIUM] /refresh only tests the no-token 401 — success/rotation and expired/invalid paths untested (security-critical).
-- [x] [LOW] Logout asserts only statusCode<500, never that the refresh cookie is cleared (name overstates the assertion).
-
-## src/__tests__/customers.schema.test.ts
-
-- [x] [MEDIUM] Trivial: only name empty/valid + one partial update; no NaN-coercion, email/ICO/DIC format, or nullable-field coverage.
-
-## src/__tests__/env.test.ts
-
-- [x] [LOW] Asserts shape only, never the validation FAILURE path (missing/short secret, bad port) which is the point of env validation.
-
-## src/__tests__/exchange-rates.test.ts
-
-- [x] [HIGH] Module-level rateCache/rateCacheTime never reset between tests (beforeEach resets only mockFetch) — the "throws when API fails and no cache" test passes only because it happens to run before the cache is populated; order-dependent/brittle.
-- [x] [MEDIUM] Conversion tests share the uncleared cache — once "today" is cached, later mockFetch resolutions are ignored on hit, asserting stale rates (false confidence).
-- [x] [LOW] No test for the amount!=1 path (CNB rates per 100 units, e.g. JPY/HUF) where rate/r.amount matters — the most money-bug-prone branch is untested.
-
-## src/__tests__/helpers.ts
-
-- [x] [LOW] extractCookie splits on first "=" via split("=")[1], truncating base64/JWT values containing "=" (latent; no caller exercises it); `response: any`.
-
-## src/__tests__/invoices.service.test.ts
-
-- [x] [MEDIUM] Inputs use duck-typed {toNumber:()=>N} stand-ins, not real Prisma.Decimal — a regression in real-Decimal handling wouldn't be caught; the "null quantity" test (40) actually passes 0, not null (name lies).
-- [x] [MEDIUM] No apply_vat:true with mixed per-line vat_rate, no currency-conversion, no negative/discount line — narrow surface for money logic.
-
-## src/__tests__/manual-create.test.ts
-
-- [x] [MEDIUM] afterEach deleteManys number_sequences type="shared" (16) — destructive shared global state also used by numbering.test.ts (serialized so safe, but resets the live shared counter).
-- [x] [LOW] Assertions guard with `if (!("id" in res)) return;` (37,50,116,132) — a failed create silently passes the test; attachment test checks only name+truthiness, not size/content.
-
-## src/__tests__/nas-file-manager.test.ts
-
-- [x] [LOW] Only traversal REJECTIONS tested (moveItem destination path not tested; "rejected" asserts a substring without confirming nothing was deleted/moved); no positive "legitimate path accepted" test (a reject-everything bug would pass).
-
-## src/__tests__/nas-project-folder.test.ts
-
-
-## src/__tests__/numbering.test.ts
-
-- [x] [MEDIUM] Skip-taken preview tests assume a fresh counter, but real projects/quotations rows in the test DB may already hold the first number — second!==first can pass for the wrong reason / the create could collide on the unique column.
-- [x] [LOW] "increments" asserts only num1!==num2 (not strictly +1 / year/format preserved); NO concurrency test for the SELECT...FOR UPDATE path the whole fileParallelism:false workaround exists to protect.
-
-## src/__tests__/plan.test.ts
-
-- [x] [MEDIUM] noPermUserId is "second user in DB" reused for two meanings across two beforeAlls; if the DB has only one user it falls back to admin and the scoping assertion toEqual([]) is wrong-for-the-right-reason masked.
-- [x] [LOW] Far-future created_at (2037) to dodge the 2038 ceiling (brittle); updateEntry doesn't test inactive/unknown category or date_from>date_to; assertNotPastDate "today" boundary (the bug-prone path) untested.
-
-## src/__tests__/planAuditDescription.test.ts
-
-
-## src/__tests__/planCategory.test.ts
-
-- [x] [MEDIUM] Dedupe test asserts \_2 but cleanup is keyed to in-memory ids (afterAll), so a mid-run crash leaves rows that make the next run assert \_3 and fail (slug-prefix cleanup would be safer).
-- [x] [LOW] No duplicate-label-on-update negative test, no deactivate/reactivate test; slugify empty-result collision (slugify("\*\*\*")→"") untested.
-
-## src/__tests__/received-invoices-vat.test.ts
-
-- [x] [LOW] Solid value checks but no half-cent rounding edge, no negative/credit-note amount; rounding pinned via toBeCloseTo rather than the stored 2-dp value.
-
-## src/__tests__/schema-nan.test.ts
-
-- [x] [MEDIUM] Proves "not-a-number" is rejected but never that a valid numeric STRING ("2") is coerced/accepted — the whole point of the form-coercion helper (string→number) is untested.
-- [x] [LOW] Only CreateOrder/CreateQuotation covered; the ~150 other duplicated coercion sites (invoices/received-invoices/trips/plan) have no NaN test.
-
-## src/__tests__/setup.ts
-
-- [x] [LOW] Loads .env.test but doesn't assert it exists or that DATABASE_URL targets a TEST db (vitest.config also loads it with override:true — redundant); a missing .env.test silently runs against whatever env is present (non-test-DB risk).
-
-## src/__tests__/warehouse.test.ts
-
-- [x] [MEDIUM] Shared `counter` for location codes + per-describe createdItemId/createdCategoryId in closure → tests within a describe are order-dependent (one early failure cascades).
-- [x] [LOW] "deactivates an item (soft delete)" actually asserts a HARD delete (404) — name lies and would mask a future intended soft-delete; FIFO verified only by summed batch quantity, never that the OLDEST batch is consumed first (core stock-valuation logic unverified); no partial-issue-across-batches / negative-qty rejection / reservation+issue-simultaneous-subtraction tests; hardcoded item_number "ITM001" + item_id:1 in a 403 test (fragile).
-
-## Suite-level (tests)
-
-- [x] [MEDIUM] Server-side only — ZERO frontend/component tests: React Query mutations, api.ts token-refresh/dedup, UI VAT/number formatting, and permission-gated rendering are entirely unverified.
-- [x] [LOW] buildApp/generateToken/no-perm-user bootstrap copy-pasted across ai/plan/warehouse tests instead of helpers.ts (~150 lines of drift-prone duplication).
-

-
-
-## .claude/settings.json
-
-
-## boneyard.config.json
-
-
-## .claude/settings.local.json
-
-- [x] [LOW] Permission allowlist contains stale entries pointing at the OLD PHP app (find ...boha-app ...\*.php, lines 4-9) — harmless (gitignored, local-only) but dead config from the pre-rewrite project.
-
-## CLAUDE.md
-
-- [x] [LOW] Otherwise excellent and current (counts verified: 52 models, 17 test files/195 tests, 114 admin tsx). One doc-vs-code drift: it states `vatFromGross` (gross VAT) is used "by both the manual form and the AI import," but the JSON single-create path in received-invoices.ts still uses the net `amount*rate/100` formula (see that file's [HIGH]) — the convention is documented as fully applied when one code path was missed. Strength worth preserving: the conventions section + the 2026-06-06 audit reference keep entropy in check.

-## Fix Log — Wave F-1: Schemas (verified: tsc 0, vitest 195/195)
-
-**Foundation:** added NaN-guarded coercion helpers to `src/schemas/common.ts` (`numberFromForm`, `numberInRange`, `nonNegativeNumberFromForm`, `positiveNumberFromForm`, `intIdFromForm`, `nullableNumberFromForm`, `nullableIntIdFromForm`, `booleanFromForm`, `isoDateString`, `timeString`) — the root-cause fix for the ~150× duplicated unguarded idiom. Replaced `ZodSchema` import with `z.ZodType`.
-
-- **[HIGH] common.ts no shared helpers** → FIXED (helpers added above).
-- **[HIGH] trips.schema NaN start_km/end_km/ids** → FIXED (`intIdFromForm`/`nonNegativeNumberFromForm`/`isoDateString`/`booleanFromForm`, route `end_km<start_km` guard now sees finite numbers); route bug closed.
-- **[HIGH] received-invoices month/year/amount/vat** → FIXED (`numberInRange(1,12)`/`(2000,2100)`/`(0,100)`, `nonNegativeNumberFromForm`).
-- **[HIGH] warehouse movement quantities/FKs NaN/negative** → FIXED (`positiveNumberFromForm`/`nonNegativeNumberFromForm` for qty/price, `intIdFromForm`/`nullableIntIdFromForm` for all FKs).
-- **[HIGH] attendance pervasive NaN** → FIXED (ids→intId, project_id→nullableIntId, numerics→numberFromForm, times→`timeString`, minutes→`numberInRange(0,59)`).
-- **[MEDIUM] auth/users/profile password no .max()** → FIXED (`.max(200)`); totp_code digits-only regex; usernames/names capped.
-- **[MEDIUM] settings security numerics unguarded** → FIXED (`max_login_attempts`→1..100, `lockout_minutes`→1..1440, `max_requests_per_minute`→1..100000, vat 0..100, breaks non-negative); array(any)→array(unknown).max; email fields `.email()`.
-- **[MEDIUM] customers/settings z.array(z.any())** → FIXED (`z.array(z.unknown()).max(N)`).
-- **[MEDIUM] bank-accounts unbounded iban/bic/currency** → FIXED (`.max(255)`; format regexes intentionally not added to avoid rejecting valid edge cases).
-- **[MEDIUM] plan/projects update-FK inconsistency** → FIXED (shared helpers; plan local intFromForm/isoDate now alias shared ones; project Update FKs → nullableIntId).
-- **[LOW] vehicles/scope-templates/offers/orders/invoices/leave/roles/ai NaN + unbounded text + bool idiom** → FIXED (helpers + `.max()` caps + `booleanFromForm` + date `isoDateString` where safe). vat_rate→numberInRange(0,100). permission_ids→array(int().positive()).max(500).
-- **[LOW] "plain z.object not z.strictObject" (all schemas)** → RESOLVED (intentional): converting request bodies to `strictObject` would reject forward-compatible payloads (extra fields the client may send); the strip-unknown behavior is the safer default. Convention noted; not changed.
-- **[LOW] status/currency free strings (invoices/orders/received/projects/settings)** → RESOLVED: capped `.max(20)`/left as bounded strings; enum values not guessed (a wrong enum would reject valid requests). Models with an existing `z.enum` (offers/orders status) already correct.

-
-## Fix Log — Wave F-2a: Backend routes + NAS/utils/scripts (verified: tsc 0, vitest 195/195)
-
-**Security (HIGH):**
-- roles.ts → POST/PUT now require admin role; reject role named "admin", enforce name uniqueness, block rewriting the admin role's permissions; role+permissions wrapped in one `$transaction`.
-- totp.ts → `/enable` (and `/setup`) now use `config.totp.algorithm/digits/period` (not hardcoded SHA1/6/30); backup-code loop early-exits on match.
-- services/auth.ts → on refresh-token reuse, the whole token family is revoked (`deleteMany` by user) + warn-logged, before 401.
-- trips.ts `GET /users` and vehicles.ts `GET /` → now permission-guarded (`requireAnyPermission`) instead of bare `requireAuth` (info-disclosure closed).
-- received-invoices.ts → JSON single-create now uses `vatFromGross` (gross-VAT consistent across all 3 paths).
-- orders-pdf.ts → custom client-supplied items now require `orders.edit`; `orders.view`-only callers get STORED order items (fabrication closed); `.passthrough()`→`z.looseObject` + bounded item schema.
-- nas-offers-manager.ts → all 5 silent `catch {}` now `console.error` with context.
-
-**Correctness/convention:**
-- Raw `reply.send` envelopes → `success()`/`paginated()` across attendance/customers/leave-requests/projects/invoices/received-invoices.
-- scope-templates.ts → `logAudit` added to all template mutations; DELETE id NaN-guarded + existence-checked.
-- leave-requests.ts → approval path now persists `reviewer_note`.
-- dashboard.ts → `today_plan` N+1 replaced with one `findMany({where:{key:{in}}})` + Map.
-- audit-log.ts / company-settings.ts → numeric query/body NaN-guarded (→400 not 500).
-- projects.ts → POST `/:id/notes` audited; DELETE body validated; trips odometer no longer regresses (recompute via MAX).
-- project-files.ts → folder-create/move bodies validated via parseBody (inline Zod).
-- invoices-pdf.ts → `JSON.parse(custom_fields)` guarded; offers-pdf cleanQuillHtml strips js/data/vbscript.
-- orders.ts → from-quotation multipart `quotationId` validated via schema (NaN-safe).
-- quotations.ts → redundant 2nd findUnique removed; NAS-delete catch logged; `(result as any)` typed.
-- html-to-pdf.ts → chromium path now probed via `fs.existsSync` through the fallback list.
-- rotate-totp-key.ts → reuses the dual-format `decrypt` from utils/encryption (handles PHP-legacy secrets); encryption.ts refactored to add `decryptWithKey`/`encryptWithKey` (backward compatible, wire format unchanged).
-- migrate-received-invoices-to-nas.ts → read-back size check before nulling `file_data`.
-- seed.ts → hard guard refusing to run when `APP_ENV==="production"`.
-
-**Resolved-as-noted / deferred (ticked):**
-- attendance.ts `project_logs` ownership → FIXED (owner-or-`attendance.manage`).
-- nas-financials-manager.ts "sync fs blocks event loop" → DEFERRED (async rewrite large/risky; documented); `saveIssuedInvoicePdf` isConfigured guard added.
-- nas-file-manager.ts TOCTOU/symlink, encryption.ts format-detection, pagination/czech-holidays TZ → documented via comments (no behavior change; crypto wire format untouched).
-- totp.ts `/enable` change-flow (LOW), plan.ts UTC note → low-risk, left as-is with rationale.
-- scope/item-template audit entries omit `entityType` (no matching `EntityType` union member; action+entityId+Czech description still recorded).

-## Fix Log — Wave F-2b: Services + warehouse route (verified: tsc 0, vitest 195/195)
-
-**Concurrency / data-integrity (HIGH):**
-- warehouse.service: `cancelReservation` now in `$transaction` with FOR UPDATE on the reservation row; `confirmIssue`/`confirmInventorySession` lock affected item + batch rows (ascending-id order, no new deadlock) before read-modify-write; `selectFifoBatches` adds `{id:"asc"}` tie-break; confirm rejects `batch.item_id !== line.item_id`; `getBelowMinimumItems` N+1 → one `groupBy`.
-- warehouse.ts route: report endpoints bounded (pagination + `REPORT_SOURCE_CAP=5000`); PUT line replacements wrapped in `$transaction`; attachment save does a compensating NAS delete on DB-insert failure; NaN/status filters guarded. **Report default limit raised to 2000 (max 5000) via new `parsePagination(query,{defaultLimit,maxLimit})` so reports stay complete, not silently truncated to 25.**
-- attendance.service: `lockUserRow` `$executeRaw`→`$queryRaw` (lock now holds); `getBalances` N+1 → one `findMany({user_id:{in}})`; `getStatus` independent queries via `Promise.all`; `createLeave` books Dec→Jan days against each day's own year; `deleteAttendance` gained optional owner-or-admin params (backward compatible); `DEFAULT_VACATION_TOTAL=160` constant.
-- exchange-rates: `fetch` now has `AbortSignal.timeout(8000)`; per-key TTL (not one global timestamp); `data.rates` array-validated.
-- numbering.service: first-of-year INSERT race handled (P2002 catch + single retry); `releaseSequence` in `$transaction` with FOR UPDATE.
-- users.service / offers.service: uniqueness checks moved INSIDE the create transaction (TOCTOU → proper 409, not 500).
-
-**Correctness / quality:**
-- invoices.service: three money/VAT impls unified through one `computeMoney` core (outputs byte-identical; test still passes); `getInvoiceStats` awaits via `Promise.all`; `Record<string,any>`→typed `InvoiceInput`; deleteInvoice year-parse guarded.
-- invoice-alerts: created-invoice amount now gross; per-invoice log N+1 → one findMany; dead ternary removed; `createMany({skipDuplicates})`.
-- orders.service: status→project-status sync extracted to one helper; deleteOrder FK guard moved inside the tx.
-- offers.service: deleteOffer cleans the NAS PDF. projects.service: deleteProject is DB-first then NAS (no orphan); updateProject logs rename failure.
-- planCategory.service: `̀-ͯ` combining-marks strip; bounded uniqueKey loop. plan.service: audit-label N+1 batched via `Promise.all` (descriptions identical; bulk skips per-entry labels).
-- mailer: optional SMTP transport when `SMTP_HOST` env present (sendmail default unchanged; no .env edited); `to` validated.
-- system-settings: JSON.parse shape-validated. leave-notification: `formatDate` uses `isNaN(getTime())`. ai.service: model-output `JSON.parse` wrapped.
-
-**Deferred (ticked, rationale):** God-file splits (warehouse.ts route 2399, attendance.service 1700) — large refactors deferred for unattended safety, documented in-file; `getInvoice` null-return kept (route depends on it); nas-financials sync-fs kept (async rewrite risky), documented.
-
-**Controller fix:** `invoices.service.ts` `InvoiceItemInput` widened to allow `null` (schema yields nullish) to clear a tsc error from the refactor.

-## Fix Log — Wave F-3a: Frontend UI kit + warehouse pages + components (verified: tsc 0, build 0)
-
-**Rules-of-Hooks (HIGH) — moved every hook above the early `return <Forbidden/>`:** WarehouseInventoryDetail, WarehouseInventoryForm, WarehouseIssueDetail, WarehouseIssueForm, WarehouseItemDetail, WarehouseReceiptDetail, WarehouseReceiptForm.
-**Stale-closure confirm bugs (MEDIUM):** WarehouseIssueForm/ReceiptForm `confirm*` and WarehouseSuppliers `toggleActive` now pass the id as the mutation variable (no more `/0/...` or collection-root PUT).
-**UI kit:** Field.tsx → `useId` label `htmlFor` + child `id` injection + `aria-describedby`/`aria-invalid` (system-wide a11y); ConfirmDialog/Modal freeze `cancelText`(+`confirmVariant`); Card `disableContentPadding`/`contentProps`; Checkbox `disabled/name/id/indeterminate/required`; DataTable mobile sort control + desktop action-cell `stopPropagation`; ProgressBar/Tabs aria; AppShell logout-timeout cleanup; navData boundary-safe active; Alert Czech close label; LoadingState aria fallback.
-**Warehouse pages:** WarehouseIssueDetail project link → RouterLink (SPA nav); WarehouseInventoryForm `actual_qty` parseDecimal/NaN-guard; WarehouseInventory `items` col → `_count.items`; WarehouseReports tabs → React Query (in `["warehouse"]` cache) + error Alert + formatDate; WarehouseReservations → `useApiMutation` + NaN guard; WarehouseCategories `sort_order` Number+guard; dead `/0/` fallbacks + duplicated MovementRow types removed.
-**Components:** OrderConfirmationModal resets state on reopen + no close-on-error; ShiftFormModal `leave_hours` NaN→0 + per-instance ref key counter; PlanCellModal typed payload props (no `any`); ProjectFileManager drag-depth counter + logged catches; PlanRangeChips dead `readonly` prop removed (+ PlanGrid call site); PlanGrid `useMemo` project Map + memoized days; PlanCategoriesModal label `key`; AlertContainer stacking offset; misc keys/labels.
-
-**Deferred (ticked, rationale):** Modal live-children freeze (snapshotting ReactNode form children breaks controlled inputs); WarehouseItemDetail error-effect→render-branch (also toasts; behavior risk); WarehouseReceiptForm hand-rolled dropzone→kit FileUpload (kit lacks drag-drop/auto-upload); ShortcutsHelp `return null` (still rendered by AppShell — kept, commented); ErrorBoundary telemetry (no telemetry service exists — commented hook); various LOW form-seed-effect patterns (intentional).

-## Fix Log — Wave F-3b: Remaining pages + dashboard/odin components + hooks/data-layer (verified: tsc 0, build 0, vitest 195/195)
-
-**Rules-of-Hooks (CRITICAL/HIGH) — moved every hook above the early permission return:** OrderDetail, ProjectDetail (CRITICAL); Settings, Trips, TripsAdmin, AttendanceBalances, AuditLog, LeaveApproval (HIGH). (Users, Vehicles were verified ALREADY correct — finding prose said "after" but line numbers showed before.)
-**UTC-date persisted-value fixes (MEDIUM):** InvoiceDetail due_date default/issue/due/tax/`computedDueDate` → local-date helper `addDaysLocalStr`/`normalizeDateStr` (no more `toISOString().split` reaching the saved payload); ReceivedInvoices `toDateInput` → `normalizeDateStr`; Attendance `calculateBusinessDays` → local parse; Invoices overdue tint → local string compare.
-**Invalidation gaps (HIGH/MEDIUM):** DashQuickActions trip POST → invalidate `["trips"]`+`["dashboard"]`; DashProfile PUT → `["dashboard"]`+`["users"]`; Attendance leave submit → added `["leave"]`.
-**Other:** OfferDetail heartbeat effect dep `isCompleted` added (stale closure); Projects search debounced; Vehicles raw `<Chip>`→kit StatusChip; parseInt radix (Trips/Vehicles/OffersCustomers); Login `loginToken!` guarded; AttendanceLocation dead LoadingState branch fixed; ReceivedInvoices render-phase ref→effect.
-**Hooks/data-layer:** usePlanWork optimistic rollback moved to `onMutate`-context (+typed bodies, `res.ok` guard); attendanceHelpers `getTimePart` now string-parses (TZ-safe); dashboardHelpers dead `STATUS_DOT_CLASS` removed; ThemeContext `DEFAULT_THEME_MODE` constant + cross-tab `storage` listener (+ MuiProvider now imports the constant — drift closed); theme.ts reduced-motion guard on containedPrimary; `attendanceLocationOptions`/`sessionsOptions` routed through `jsonQuery` (ok/401 guards); useReducedMotion lazy initializer; ItemPicker debounce; ReservationPicker stale-selection reset; OdinSidebar row keyboard-accessible; dashboard widgets reduced-motion branch.
-
-**Deferred (ticked, rationale):** AuthContext `apiRequest`↔`apiFetch` consolidation (high auth-regression risk; cross-referenced in comments); useAttendanceAdmin split/RQ-migration (large refactor); big-file splits (InvoiceDetail/OfferDetail/Settings/CompanySettings/ReceivedInvoices/AttendanceHistory); `usePaginatedQuery` precise option typing (TanStack `enabled` contravariance over-constrains callers — reverted to documented `any`, data shape still enforced); untyped query-row `Record<unknown>` LOWs (typing every row = large churn, accepted); useModalLock body-vs-html (still used; documented). 
-
-**Controller fixes:** projects.ts DeleteSchema default, invoices.service InvoiceItemInput null-widening, usePaginatedQuery generic revert, OdinComposer ref cast restored, DashQuickActions message fallback, MuiProvider DEFAULT_THEME_MODE import.

-- **[HIGH] No linter / unpinned formatter** → FIXED: added ESLint flat config (`eslint.config.mjs`) with `typescript-eslint` + **`react-hooks/rules-of-hooks` as ERROR** + `react-refresh`; Prettier as a real devDep (`.prettierrc.json`/`.prettierignore`); npm scripts `lint`/`lint:fix`/`format`/`format:check`/`typecheck`. **The linter immediately caught a real Rules-of-Hooks bug the fix-agents had missed (`PlanCellModal` EditForm — `useState`s after an early `return null`); fixed by extracting `computeEditFormInitial` and moving the guard after all hooks.** `npm run lint` = 0 errors (110 advisory warnings).
-- **[HIGH] Tests never type-checked** → FIXED: added `tsconfig.test.json` (node + `vitest/globals`, includes `src/__tests__` + the fastify `.d.ts` augmentation) referenced from the solution `tsconfig.json`, so `tsc -b` now covers the suite. It surfaced **7 real type holes** in `manual-create.test.ts`/`plan.test.ts` (optional `id`/`unknown` data) — all fixed.
-- **[MEDIUM] Dependency vulns** → FIXED: `npm audit fix` (non-breaking) took **8 vulns → 3** (remaining `quill`/`file-type` need breaking majors — DEFERRED; quill XSS is mitigated by the DOMPurify-everywhere sanitization).
-- **[MEDIUM] Dead dependencies** → FIXED: removed `react-datepicker`, `hi-base32`, `@types/mysql`.
-- **[MEDIUM] No README / stale `.env.example`** → FIXED: wrote a real README (setup/run/build/test/gates/migrations); rewrote `.env.example` with every env var `config/env.ts` reads (+ optional SMTP, ANTHROPIC_API_KEY).
-- **[MEDIUM] ~77 `any`** → REDUCED: typed InvoiceInput, PlanCellModal props, usePlanWork bodies, dashboard fetch results, etc.; the remainder are now surfaced as ESLint warnings. Tracked, not silent.
-- **[MEDIUM] God-files** → DEFERRED: large splits are unsafe in an unattended pass; documented in-file and in CLAUDE.md.
-- **[LOW] `.gitignore`** → FIXED: added `*.tsbuildinfo`, `*.bak`, `.playwright-mcp/`.
-- **[LOW] Per-request auth caching** → DEFERRED: adding a cache to the auth hot path unattended is risky; documented as a future optimization.
-- **Infra LOW notes** → audit.ts now uses `instanceof Prisma.Decimal`; types/index.ts JwtPayload.role hazard documented; server.ts vite-import / env Date.toJSON / security CSP-prod-only / totp logging confirmed intentional (by-design, no change).
-- **CLAUDE.md** gate line updated to include `npm run lint` + the test-typecheck note.
-
-## Fix Log — config/doc closures
-- tsconfig.server.json/tsconfig.app.json "tests not typechecked / noUnusedLocals off" → FIXED (tsconfig.test.json now type-checks tests; ESLint no-unused-vars covers dead-code).
-- .env.example stale, format-on-save prettier undeclared → FIXED (rewritten; prettier now a real devDep + .prettierrc.json).
-- CLAUDE.md vatFromGross doc-vs-code drift → CLOSED (received-invoices JSON path now uses vatFromGross, so the doc is accurate).
-- .claude/settings.local.json stale PHP allowlist → RESOLVED (gitignored local-only config; harmless, left to the user).
-
-## Fix Log — Prisma schema (verified: prisma validate ✓, generate ✓, tsc 0, vitest 195/195)
-Edited `prisma/schema.prisma` + regenerated client + staged a **PENDING** migration `prisma/migrations/20260609000000_audit_schema_hardening/` (NOT applied — needs the user to run `prisma migrate deploy`/`migrate dev` with the dev server stopped, per policy; the migration header documents the data-safety checks).
-- [HIGH] sklad_* relations now have explicit `onDelete` (Cascade line→header, Restrict line→master-data, SetNull on the genuinely-optional `*_by`/supplier/category refs; required "project" refs → Restrict since SetNull is invalid on a non-null column).
-- [MEDIUM] `@unique` on receipt_number/issue_number/session_number.
-- [MEDIUM] Financial FKs (invoices/orders/projects/quotations) made explicit `onDelete: Restrict` (prevents orphaning; note: some were the optional default SetNull — RESTRICT is the safer intent).
-- [MEDIUM] New `@@index` on sklad_issues(project_id, issued_by), sklad_receipts(supplier_id, received_by), bank_accounts(is_default).
-- [LOW] Removed the duplicate audit_logs created_at index. Did NOT add @updatedAt (runtime risk), convert status→enum (data risk), or add FKs to deliberately-FK-less user-reference columns (by design).
-
-## Fix Log — Tests (verified: tsc 0 incl. tests, vitest 243/243 — was 195)
-**Flakiness/correctness (the real bugs):**
-- exchange-rates: added `__resetRateCacheForTest()` (test-only, no runtime change) + `beforeEach` reset → no more order-dependent stale-cache; added the `amount!=1` (per-100-unit) test.
-- ai: over-budget row cleaned in-test + "sums only current month" now asserts an exact delta → order-independent.
-- numbering: "increments" now asserts strict +1 / format / year; skip-taken previews seed high so they can't pass for the wrong reason.
-- planCategory: slug-prefix cleanup so a crashed run can't shift dedupe to `_3`.
-- plan: dedicated distinct non-admin `scopeUserId` for employee-scoping (can't be the admin / collapse to 1).
-- manual-create: `if (!("id" in res)) return` → `failResult()` that throws (no silent pass); attachment test now asserts exact bytes.
-**Misleading names fixed:** warehouse "soft delete"→"hard-deletes…404"; invoices "null quantity" now passes a genuine null.
-**New high-value coverage:** auth happy-path login + refresh-rotation + logout-cookie-cleared; `verifyAccessToken` happy path + pinned `hashToken` vector; schema-nan valid-string-COERCION positives (orders/quotations/trips/received-invoices/warehouse); invoices real `Prisma.Decimal` + mixed-VAT + discount line; customers schema breadth; received-invoices half-cent rounding pinned to 2dp; nas-file-manager POSITIVE accept + destination-traversal reject; plan today-boundary; warehouse FIFO oldest-first.
-**helpers/setup:** `extractCookie` no longer truncates `=`-containing values; setup.ts now warns if DATABASE_URL isn't a test DB.
-**Suite-level:** [MEDIUM] no component tests → DEFERRED (a component-test harness is a substantial separate initiative; backend coverage materially improved); [LOW] duplicated buildApp/token bootstrap → acknowledged (consolidation is a safe future cleanup; not done to avoid churn across passing suites).
-
-> ⚠️ **Finding for the user:** there is **no `.env.test` file** — the suite runs against the dev DB named `app` (per `.env`). Create a dedicated `.env.test` pointing at a throwaway test DB, then the new `setup.ts` guard can be upgraded from a warn to a hard throw.
-
----
-
-## Verification Round (5 independent adversarial verifiers + fixes)
-
-After all findings were fixed and ticked, 5 fresh agents re-audited the fixes against the original findings + current code, and hunted for regressions. **Most fixes VERIFIED correct; the verification caught issues a self-review would have missed — all now fixed:**
-
-**3 REGRESSIONS I had introduced (validation now rejecting valid input) — FIXED + regression-tested:**
-1. `settings` email fields `.email()` rejected the empty string the Settings form submits for un-filled emails → it blocked saving ALL system settings. FIXED: new `emailOrEmpty` helper (accepts "" | valid email) in common.ts; applied to settings + warehouse-supplier emails.
-2. `warehouse` supplier `email` same issue → FIXED (emailOrEmpty).
-3. `trips` `trip_date` (and by extension `projects`/`leave` date fields) used strict `isoDateString`, which rejected the `"YYYY-MM-DDT00:00:00"` an edit form re-submits (the `@db.Date` toJSON round-trip) → FIXED: `isoDateString`/`timeString` now strip a trailing time component before validating (output stays date-only). Added 4 regression tests (schema-nan.test.ts → 24 tests).
-
-**Concurrency issues the verifier found — FIXED:**
-4. `cancelIssue` was left OUT of the new lock discipline (locked batches in unsorted issue-line order, no item gate) → a residual deadlock window vs `confirmIssue`. FIXED: now locks affected items then batches in ascending id order, matching confirmIssue/confirmInventorySession.
-5. `$executeRaw` vs `$queryRaw` inconsistency: the warehouse lock helpers (`lockParentRow`/`lockRowsForUpdate`) + `cancelReservation` still used `$executeRaw` for `SELECT … FOR UPDATE` while the attendance fix switched to `$queryRaw` (the reliable form). FIXED: unified all warehouse FOR-UPDATE locks on `$queryRaw`.
-6. `createUser` concurrent-duplicate surfaced as 500 not 409 → FIXED: catch P2002 → 409.
-
-**Verified clean (no issues found):** all frontend Rules-of-Hooks (enforced by the lint rule), UTC-date fixes, invalidation gaps, stale-closure confirms, Field a11y; all infra (eslint/test-typecheck/dead-deps/audit/README/.env); prisma schema + migration consistency; the security fixes (roles escalation, totp, token-family revoke, VAT gross, orders-pdf authz, NAS catches).
-
-**Acknowledged residual (LOW, pre-existing, not introduced here):** roles.ts PUT metadata-update sits just outside the permission-rewrite transaction; the refresh-reuse→401 path is now tested but the family-revocation side-effect lacks a dedicated assertion.
-
-### FINAL GATES (after verification fixes): tsc 0 · build 0 · vitest **247/247** (was 195) · eslint **0 errors**.

-# Deployment Guide — boha-app-ts (Ubuntu Server)
-
-Migration from PHP boha-app to TypeScript boha-app-ts on the same Ubuntu server.
-Both apps share the same MySQL database. The PHP app stays running during migration.
-
----
-
-## Prerequisites
-
-- Ubuntu server with the PHP boha-app already running
-- nginx with SSL (Let's Encrypt) already configured
-- MySQL database already running with production data
-- NAS storage mounted (e.g., `/mnt/nas/02_PROJEKTY`)
-- SSH access to the server
-
----
-
-## Phase 1: Prepare on Dev Machine (Windows)
-
-### 1.1 Create Prisma migration baseline
-
-```bash
-cd D:\cortex\boha-app-ts
-mkdir -p prisma/migrations/0_init
-npx prisma migrate diff --from-empty --to-schema-datamodel prisma/schema.prisma --script > prisma/migrations/0_init/migration.sql
-npx prisma migrate resolve --applied 0_init
-git add prisma/migrations/
-git commit -m "chore: create Prisma migration baseline"
-```
-
-### 1.2 Build the application
-
-```bash
-npm run build
-```
-
-This creates:
-- `dist/` — compiled server (Node.js)
-- `dist-client/` — compiled frontend (static files)
-
-### 1.3 Generate new production secrets
-
-```bash
-openssl rand -hex 32
-# Save this as JWT_SECRET
-
-openssl rand -hex 32
-# Save this as TOTP_ENCRYPTION_KEY (only if you want a new key)
-```
-
-### 1.4 Test the production build locally (optional)
-
-```bash
-APP_ENV=production JWT_SECRET=<your-dev-key> TOTP_ENCRYPTION_KEY=<your-dev-key> DATABASE_URL=<your-dev-db> node dist/server.js
-```
-
-Verify it starts and responds at `http://localhost:3001/api/health`.
-
----
-
-## Phase 2: Prepare Ubuntu Server
-
-### 2.1 Install Node.js 22
-
-```bash
-curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash -
-sudo apt-get install -y nodejs
-node -v
-npm -v
-```
-
-### 2.2 Install PM2
-
-```bash
-sudo npm install -g pm2
-```
-
-### 2.3 Create application directory
-
-```bash
-sudo mkdir -p /var/www/boha-app-ts
-sudo chown $USER:$USER /var/www/boha-app-ts
-```
-
----
-
-## Phase 3: Transfer Files to Server
-
-### 3.1 Copy built files
-
-From your Windows machine (Git Bash or PowerShell with SCP):
-
-```bash
-scp -r dist/ dist-client/ package.json package-lock.json prisma/ scripts/ .env.example user@server:/var/www/boha-app-ts/
-```
-
-Or use rsync if available:
-
-```bash
-rsync -avz --exclude node_modules --exclude .env dist/ dist-client/ package.json package-lock.json prisma/ scripts/ .env.example user@server:/var/www/boha-app-ts/
-```
-
-### 3.2 Install production dependencies on server
-
-```bash
-ssh user@server
-cd /var/www/boha-app-ts
-npm install --production
-npx prisma generate
-```
-
----
-
-## Phase 4: Configure Environment
-
-### 4.1 Create production .env
-
-```bash
-cd /var/www/boha-app-ts
-cp .env.example .env
-nano .env
-```
-
-Fill in:
-
-```env
-# Database — same as the PHP app
-DATABASE_URL=mysql://user:password@localhost:3306/your_db_name
-
-# Server
-PORT=3001
-HOST=127.0.0.1
-APP_ENV=production
-
-# Auth — use the NEW secrets generated in step 1.3
-JWT_SECRET=<paste-new-jwt-secret>
-ACCESS_TOKEN_EXPIRY=900
-REFRESH_TOKEN_SESSION_EXPIRY=3600
-REFRESH_TOKEN_REMEMBER_EXPIRY=2592000
-
-# TOTP — use SAME key as PHP app (unless you want to re-encrypt)
-TOTP_ENCRYPTION_KEY=<same-key-as-php-app>
-
-# NAS — Linux mount point
-NAS_PATH=/mnt/nas/02_PROJEKTY
-MAX_UPLOAD_SIZE=52428800
-
-# Email
-CONTACT_EMAIL_TO=manager@boha-automation.cz
-CONTACT_EMAIL_FROM=web@boha-automation.cz
-SMTP_FROM=noreply@boha-automation.cz
-
-# CORS — your production domain(s)
-CORS_ORIGINS=https://app.boha-automation.cz,https://www.boha-automation.cz
-```
-
-**Important decisions:**
-
-| Setting | Recommendation |
-|---------|---------------|
-| `JWT_SECRET` | **New key.** All PHP sessions will be invalid — users re-login. This is expected. |
-| `TOTP_ENCRYPTION_KEY` | **Same key as PHP app.** Avoids re-encrypting all TOTP secrets. |
-| `DATABASE_URL` | **Same database as PHP app.** Both apps share it. |
-| `NAS_PATH` | **Linux mount point** instead of Windows drive letter. |
-
----
-
-## Phase 5: Database Setup
-
-### 5.1 Mark Prisma baseline as applied
-
-```bash
-cd /var/www/boha-app-ts
-npx prisma migrate resolve --applied 0_init
-```
-
-This tells Prisma the database already has all tables. No SQL is executed.
-
-### 5.2 Verify database connection
-
-```bash
-npx prisma db pull --print | head -20
-```
-
-Should show your existing tables.
-
----
-
-## Phase 6: TOTP Key Rotation (only if using new encryption key)
-
-**Skip this section if you're using the same `TOTP_ENCRYPTION_KEY` as the PHP app.**
-
-If you generated a new encryption key:
-
-```bash
-cd /var/www/boha-app-ts
-
-# Dry run — verify all secrets can be decrypted and re-encrypted
-npx tsx scripts/rotate-totp-key.ts <old-key> <new-key> --dry-run
-
-# If all [OK], run for real
-npx tsx scripts/rotate-totp-key.ts <old-key> <new-key>
-```
-
-After this, the PHP app's TOTP verification will break (secrets are now encrypted with the new key). Only do this when you're ready to cut over.
-
----
-
-## Phase 7: Start Application with PM2
-
-### 7.1 Create PM2 config
-
-```bash
-cd /var/www/boha-app-ts
-cat > ecosystem.config.js << 'EOF'
-module.exports = {
-  apps: [{
-    name: 'boha-app-ts',
-    script: 'dist/server.js',
-    cwd: '/var/www/boha-app-ts',
-    instances: 1,
-    env: {
-      NODE_ENV: 'production',
-    },
-  }]
-};
-EOF
-```
-
-### 7.2 Start the app
-
-```bash
-pm2 start ecosystem.config.js
-pm2 save
-pm2 startup
-# Follow the printed command to enable auto-start on boot
-```
-
-### 7.3 Verify
-
-```bash
-pm2 status
-pm2 logs boha-app-ts --lines 20
-curl http://localhost:3001/api/health
-```
-
-Expected: `{"status":"ok","timestamp":"..."}`
-
----
-
-## Phase 8: Nginx Configuration
-
-### 8.1 Create nginx config
-
-```bash
-sudo nano /etc/nginx/sites-available/boha-app-ts
-```
-
-Paste:
-
-```nginx
-server {
-    listen 443 ssl http2;
-    server_name app.boha-automation.cz;
-
-    ssl_certificate /etc/letsencrypt/live/app.boha-automation.cz/fullchain.pem;
-    ssl_certificate_key /etc/letsencrypt/live/app.boha-automation.cz/privkey.pem;
-
-    client_max_body_size 55M;
-
-    location / {
-        proxy_pass http://127.0.0.1:3001;
-        proxy_http_version 1.1;
-        proxy_set_header Upgrade $http_upgrade;
-        proxy_set_header Connection 'upgrade';
-        proxy_set_header Host $host;
-        proxy_set_header X-Real-IP $remote_addr;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-        proxy_set_header X-Forwarded-Proto $scheme;
-        proxy_cache_bypass $http_upgrade;
-    }
-}
-
-server {
-    listen 80;
-    server_name app.boha-automation.cz;
-    return 301 https://$host$request_uri;
-}
-```
-
-Adjust `server_name` and SSL paths to match your setup.
-
-### 8.2 Enable and reload
-
-```bash
-sudo ln -s /etc/nginx/sites-available/boha-app-ts /etc/nginx/sites-enabled/
-sudo nginx -t
-sudo systemctl reload nginx
-```
-
----
-
-## Phase 9: Testing
-
-### 9.1 Verify in browser
-
-Open `https://app.boha-automation.cz` and test:
-
-- [ ] Login page loads
-- [ ] Login works (users will need to re-login due to new JWT_SECRET)
-- [ ] TOTP verification works (if using same encryption key)
-- [ ] Dashboard loads with data
-- [ ] Offers — list, create, edit, PDF export
-- [ ] Orders — list, create from offer, status transitions
-- [ ] Invoices — list, create, PDF with QR code
-- [ ] Projects — list, create, file manager (upload/download)
-- [ ] Attendance — clock in/out, admin view, print
-- [ ] Trips — list, history
-- [ ] Settings — company settings, users, roles
-
-### 9.2 Check logs for errors
-
-```bash
-pm2 logs boha-app-ts --lines 50
-```
-
----
-
-## Phase 10: Cutover Strategy
-
-Both apps run simultaneously on the same database. Recommended approach:
-
-1. **Week 1:** Run both apps. Use the TS app for daily work. Fall back to PHP if issues arise.
-2. **Week 2:** If stable, redirect the main domain to the TS app.
-3. **Week 3:** Stop the PHP app.
-
-To redirect the PHP domain to the TS app, update the nginx config for the PHP domain to proxy to port 3001 instead.
-
----
-
-## Future Updates
-
-When you push code changes:
-
-```bash
-# On dev machine
-npm run build
-git push
-
-# On server
-cd /var/www/boha-app-ts
-git pull
-npm install --production
-npx prisma generate
-npx prisma migrate deploy    # runs any new migrations
-pm2 restart boha-app-ts
-```
-
----
-
-## Troubleshooting
-
-| Problem | Solution |
-|---------|----------|
-| `EADDRINUSE: port 3001` | `pm2 stop boha-app-ts` then `pm2 start` |
-| Prisma connection error | Check `DATABASE_URL` in `.env` |
-| TOTP verification fails | Verify `TOTP_ENCRYPTION_KEY` matches the key used to encrypt secrets |
-| NAS files not accessible | Check mount: `ls /mnt/nas/02_PROJEKTY`, verify permissions |
-| 502 Bad Gateway | App not running: `pm2 status`, check logs: `pm2 logs` |
-| CSS/JS not loading | Verify `dist-client/` was copied, check `APP_ENV=production` |
-| CORS errors | Check `CORS_ORIGINS` in `.env` matches your domain exactly |
-
----
-

+# Warehouse Module Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Full warehouse/inventory management module with receipts, issues, reservations, inventory sessions, FIFO batch tracking, and reporting.
+
+**Architecture:** Document-driven (header + lines) matching existing invoice/offer patterns. 13 Prisma models, REST API under `/api/admin/warehouse`, React frontend with 17 lazy-loaded pages. True FIFO via `sklad_batches` table linked to receipt lines.
+
+**Tech Stack:** Prisma 6.19.2, Fastify 5, Zod 4, React 18, TanStack React Query, NAS file storage via NasFinancialsManager

+  @@map("sklad_inventory_lines")
+}
+```
+
+- [ ] **Step 3: Add reverse relations to existing models**
+
+Add these relation fields to the `projects` model in `prisma/schema.prisma`:
+
+```prisma
+  sklad_issues       sklad_issues[]
+  sklad_reservations sklad_reservations[]
+```
+
+Add this relation field to the `users` model in `prisma/schema.prisma`:
+
+```prisma
+  sklad_receipts_received sklad_receipts[] @relation("SkladReceivedBy")
+  sklad_issues_issued     sklad_issues[]   @relation("SkladIssuedBy")
+  sklad_reservations      sklad_reservations[] @relation("SkladReservedBy")
+```
+
+Note: The `users` model likely already has multiple relations, so named relation mappings may be needed to avoid ambiguity. Use `@relation("SkladReceivedBy")` on `sklad_receipts.received_by_user`, `@relation("SkladIssuedBy")` on `sklad_issues.issued_by_user`, and `@relation("SkladReservedBy")` on `sklad_reservations.reserved_by_user`. Update the corresponding relation field definitions in the warehouse models accordingly:
+
+In `sklad_receipts`:
+
+```prisma
+  received_by_user  users? @relation("SkladReceivedBy", fields: [received_by], references: [id])
+```
+
+In `sklad_issues`:
+
+```prisma
+  issued_by_user  users? @relation("SkladIssuedBy", fields: [issued_by], references: [id])
+```
+
+In `sklad_reservations`:
+
+```prisma
+  reserved_by_user  users? @relation("SkladReservedBy", fields: [reserved_by], references: [id])
+```
+
+- [ ] **Step 4: Run migration**
+
+```bash
+npx prisma migrate dev --name add_warehouse_module
+npx prisma generate
+```
+
+Expected: Migration created and applied. Prisma client regenerated.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add prisma/schema.prisma prisma/migrations/
+git commit -m "feat(warehouse): add Prisma schema for warehouse module"
+```
+
+---
+
+### Task 2: Add Entity Types and Permissions
+
+**Files:**
+
+- Modify: `src/types/index.ts`
+- Modify: `prisma/seed.ts`
+
+- [ ] **Step 1: Add EntityType values**
+
+In `src/types/index.ts`, extend the `EntityType` union to include:
+
+```ts
+export type EntityType =
+  | "user"
+  | "role"
+  | "attendance"
+  | "leave_request"
+  | "invoice"
+  | "quotation"
+  | "order"
+  | "project"
+  | "customer"
+  | "trip"
+  | "vehicle"
+  | "bank_account"
+  | "company_settings"
+  | "leave_balance"
+  | "project_file"
+  | "audit_logs"
+  | "warehouse_item"
+  | "warehouse_receipt"
+  | "warehouse_issue"
+  | "warehouse_reservation"
+  | "warehouse_inventory"
+  | "warehouse_supplier"
+  | "warehouse_category"
+  | "warehouse_location";
+```
+
+- [ ] **Step 2: Add warehouse permissions to seed.ts**
+
+In `prisma/seed.ts`, add these entries to the `PERMISSIONS` array:
+
+```ts
+  { name: "warehouse.view", display_name: "Zobrazit sklad", module: "warehouse", description: "Prohlížet stav skladu, položky, reporty a historii pohybů" },
+  { name: "warehouse.operate", display_name: "Příjem a výdej", module: "warehouse", description: "Vytvářet a potvrzovat příjmy, výdeje a rezervace" },
+  { name: "warehouse.manage", display_name: "Správa skladu", module: "warehouse", description: "Spravovat katalog materiálů, dodavatele, lokace a kategorie" },
+  { name: "warehouse.inventory", display_name: "Inventura", module: "warehouse", description: "Vytvářet a potvrzovat inventurní sčítkání" },
+```
+
+- [ ] **Step 3: Add number sequence types to seed.ts**
+
+In the number sequence seeding section of `prisma/seed.ts`, add `"warehouse_receipt"`, `"warehouse_issue"`, and `"warehouse_inventory"` to the types array:
+
+```ts
+const types = [
+  "quotation",
+  "order",
+  "invoice",
+  "warehouse_receipt",
+  "warehouse_issue",
+  "warehouse_inventory",
+];
+```
+
+- [ ] **Step 4: Re-seed and verify**
+
+```bash
+npx prisma db seed
+```
+
+Expected: 4 new warehouse permissions created, 3 new number sequence types seeded.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/types/index.ts prisma/seed.ts
+git commit -m "feat(warehouse): add entity types, permissions, and number sequences"
+```

+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/admin/components/warehouse/
+git commit -m "feat(warehouse): add shared warehouse components"
+```
+
+---
+
+### Task 10: Sidebar & Routes
+
+**Files:**
+
+- Modify: `src/admin/components/Sidebar.tsx`
+- Modify: `src/admin/AdminApp.tsx`
+
+- [ ] **Step 1: Add warehouse entry to Sidebar.tsx**
+
+In `src/admin/components/Sidebar.tsx`, add a new item to the "Administrativa" menu section:
+
+```ts
+{
+  path: "/warehouse",
+  label: "Sklad",
+  permission: "warehouse.view",
+  matchPrefix: "/warehouse",
+  icon: (
+    <svg viewBox="0 0 24 24" fill="none" stroke="currentColor" strokeWidth="2" strokeLinecap="round" strokeLinejoin="round">
+      <path d="M21 16V8a2 2 0 0 0-1-1.73l-7-4a2 2 0 0 0-2 0l-7 4A2 2 0 0 0 3 8v8a2 2 0 0 0 1 1.73l7 4a2 2 0 0 0 2 0l7-4A2 2 0 0 0 21 16z" />
+      <polyline points="3.27 6.96 12 12.01 20.73 6.96" />
+      <line x1="12" y1="22.08" x2="12" y2="12" />
+    </svg>
+  ),
+},
+```
+
+- [ ] **Step 2: Add lazy imports and routes to AdminApp.tsx**
+
+In `src/admin/AdminApp.tsx`, add lazy imports:
+
+```tsx
+const Warehouse = lazy(() => import("./pages/Warehouse"));
+const WarehouseItems = lazy(() => import("./pages/WarehouseItems"));
+const WarehouseItemDetail = lazy(() => import("./pages/WarehouseItemDetail"));
+const WarehouseReceipts = lazy(() => import("./pages/WarehouseReceipts"));

+  () => import("./pages/WarehouseReceiptDetail"),
+);
+const WarehouseReceiptForm = lazy(() => import("./pages/WarehouseReceiptForm"));
+const WarehouseIssues = lazy(() => import("./pages/WarehouseIssues"));
+const WarehouseIssueDetail = lazy(() => import("./pages/WarehouseIssueDetail"));
+const WarehouseIssueForm = lazy(() => import("./pages/WarehouseIssueForm"));
+const WarehouseReservations = lazy(
+  () => import("./pages/WarehouseReservations"),
+);
+const WarehouseInventory = lazy(() => import("./pages/WarehouseInventory"));
+const WarehouseInventoryDetail = lazy(
+  () => import("./pages/WarehouseInventoryDetail"),
+);
+const WarehouseInventoryForm = lazy(
+  () => import("./pages/WarehouseInventoryForm"),
+);
+const WarehouseReports = lazy(() => import("./pages/WarehouseReports"));
+const WarehouseSuppliers = lazy(() => import("./pages/WarehouseSuppliers"));
+const WarehouseLocations = lazy(() => import("./pages/WarehouseLocations"));
+const WarehouseCategories = lazy(() => import("./pages/WarehouseCategories"));
+```
+
+Add routes inside the `<Route element={<AdminLayout />}>` section:
+
+```tsx
+<Route path="warehouse" element={<Warehouse />} />
+<Route path="warehouse/items" element={<WarehouseItems />} />
+<Route path="warehouse/items/:id" element={<WarehouseItemDetail />} />
+<Route path="warehouse/receipts" element={<WarehouseReceipts />} />
+<Route path="warehouse/receipts/new" element={<WarehouseReceiptForm />} />

+<Route path="warehouse/receipts/:id/edit" element={<WarehouseReceiptForm />} />
+<Route path="warehouse/issues" element={<WarehouseIssues />} />
+<Route path="warehouse/issues/new" element={<WarehouseIssueForm />} />
+<Route path="warehouse/issues/:id" element={<WarehouseIssueDetail />} />
+<Route path="warehouse/issues/:id/edit" element={<WarehouseIssueForm />} />
+<Route path="warehouse/reservations" element={<WarehouseReservations />} />
+<Route path="warehouse/inventory" element={<WarehouseInventory />} />
+<Route path="warehouse/inventory/new" element={<WarehouseInventoryForm />} />
+<Route path="warehouse/inventory/:id" element={<WarehouseInventoryDetail />} />

+- [ ] **Step 3: Commit any remaining fixes**
+
+---
+
+## Self-Review Checklist
+
+After writing the complete plan, I verified:
+
+1. **Spec coverage**: Every requirement in the design spec has a corresponding task:
+   - 13 Prisma models → Task 1
+   - 5 enums → Task 1
+   - Entity types → Task 2
+   - 4 permissions → Task 2
+   - 3 number sequence types → Task 2
+   - Zod schemas → Task 3
+   - Service (FIFO, confirm, cancel, inventory) → Task 4
+   - All API endpoints → Tasks 5-6
+   - Server registration → Task 7
+   - Query hooks → Task 8
+   - Shared components → Task 9
+   - Sidebar + routes → Task 10
+   - All 17 pages → Tasks 11-15
+   - Tests → Task 16
+   - Build verification → Task 17
+
+2. **Placeholder scan**: No TBD, TODO, or placeholder patterns found. All tasks contain actual code or specific instructions.
+
+3. **Type consistency**: Types defined in Task 8 (`WarehouseItem`, `WarehouseReceipt`, etc.) are used consistently across Tasks 9-15. Service function signatures in Task 4 match route handler usage in Tasks 5-6.

+# Deferred HIGH issues — performance & UX sprint
+
+**Created:** 2026-06-03
+**Source audit:** Parallel 5-agent production risk audit (2026-06-03)
+**Context:** All 8 CRITICAL and 3 of 8 HIGH issues were fixed in the same session.
+The 5 items below were intentionally deferred — they are not data-integrity or
+auth risks, but they are real production pain that should be addressed in a
+dedicated performance / UX sprint before the user base notices.
+
+---
+
+## #9 — N+1 queries in warehouse list/detail/report
+
+**Files:**
+
+- `src/services/warehouse.service.ts:184-199` (getBelowMinimumItems)
+- `src/services/warehouse.service.ts:629-646` (somewhere in items list)
+- `src/services/warehouse.service.ts:681-683`
+- `src/services/warehouse.service.ts:2182-2203` (report)
+
+**Pattern:** `items.map(async (i) => { const stock = await getStock(i.id); const available = await getAvailable(i.id); const value = await getValue(i.id); })` — fires N+1 round-trips per item. For a list of 50 items, that's 150 sequential queries.
+
+**Production impact:** Slow page loads (1-3s on 50 items, scales linearly). Users already complain about the items page; this is the root cause for the warehouse report being the slowest page in the app.
+
+**Fix sketch:**
+
+- Replace the `for` loop with a single grouped query: `prisma.sklad_batches.groupBy({ by: ['item_id'], _sum: { quantity: true }, where: { item_id: { in: itemIds } } })` for stocks, similar aggregates for reservations.
+- Map the grouped results back to items in JS. One query instead of N.
+- For the report view, do the same — group all batches and reservations by item_id in a single round-trip, then join with items in memory.
+- Estimated effort: M (4-6 hours including testing).
+
+---
+
+## #10 — Missing FK indexes on hot warehouse tables
+
+**File:** `prisma/schema.prisma` (no `@@index` directives on the new warehouse tables)
+
+**Missing indexes (verify against `prisma/schema.prisma` and add to a new migration):**
+
+- `sklad_receipt_lines.item_id` — every `confirmReceipt` reads/writes this
+- `sklad_issue_lines.batch_id` — every `confirmIssue` reads/writes this
+- `sklad_issue_lines.item_id`
+- `sklad_reservations.project_id` — reservation list per project
+- `sklad_reservations.item_id`
+- `sklad_item_locations.item_id`
+- `sklad_item_locations.location_id`
+- `sklad_batches.receipt_line_id` (if nullable FK)
+- `sklad_inventory_lines.item_id`
+- `sklad_inventory_lines.session_id`
+
+**Production impact:** MySQL currently does table scans for these joins. With even 10k batch rows, the receipts/issues/reservations pages will start to crawl. On production data (likely already 50k+ batches), this is a real performance cliff.
+
+**Fix sketch:**
+
+- Add `@@index([item_id])`, `@@index([batch_id])` etc. to each model in `prisma/schema.prisma`.
+- Run `npx prisma migrate dev --name warehouse_fk_indexes` (after asking user to stop dev server per CLAUDE.md).
+- Run `npx prisma generate`.
+- Verify with `EXPLAIN` on the slow queries after deploy.
+- Estimated effort: S (1-2 hours).
+
+**CLAUDE.md note:** Before running `prisma migrate dev`, the user must stop the dev server.
+
+---
+
+## #13 — Pagination does not auto-adjust after delete
+
+**Files:** All list pages (Invoices, Offers, Projects, Orders, WarehouseXxx)
+
+**Pattern:** User is on page 5 (e.g. 10 items per page, 47 total, pages 1-5). They delete the last item on page 5. Total becomes 46, but the page param is still 5. The list endpoint returns 0 results, the user sees an empty table, and the "next" button is disabled but there's no automatic jump back to page 4.
+
+**Production impact:** Confusing UX. Users have to manually click "previous" or reset filters. Doesn't cause data loss but is a small papercut that erodes trust.
+
+**Fix sketch:**
+
+- In each list page's `useQuery` error/empty handler, detect `pagination.total === 0 && page > 1` and call `setPage(page - 1)`.
+- Or more cleanly: have the API include `pagination.total_pages` and the frontend clamp `page` to `min(page, total_pages)` after each refetch.
+- Estimated effort: S (2-3 hours; touches ~10-12 pages).
+
+---
+
+## #14 — Offer lock lifecycle has multiple silent failures
+
+**File:** `src/admin/pages/OfferDetail.tsx:472-516`
+
+**Pattern:** Lock acquire, heartbeat (interval), and unlock all use `.catch(() => {})`. If any of them silently fails, the user thinks they have the lock but actually don't — or worse, the lock is held by a tab that's already closed because the unload handler also swallowed the error.
+
+**Production impact:** Two users editing the same offer can both see "You have the lock" and clobber each other's changes. Data loss in a real, low-probability but high-impact scenario.
+
+**Fix sketch:**
+
+- Replace `.catch(() => {})` with `.catch((err) => console.error("Offer lock error:", err))` at minimum.
+- Better: surface lock acquisition failures via a toast (`alert.error("Nepodařilo se získat zámek, stránka bude pouze pro čtení.")`).
+- For the unlock on unmount: best-effort `navigator.sendBeacon` or a synchronous fallback so the lock is released even if the page is closing.
+- Estimated effort: S (1-2 hours).
+
+---
+
+## #11 (audit item, not a real bug) — TOTP replay counter rewind
+
+**File investigated:** `src/utils/totp.ts:5-30`, `src/routes/admin/auth.ts:165-184`
+
+**Status:** False positive. The audit suggested `verifyResult.counter` could be lower than the actual step used. After reading the implementation:
+
+```ts
+const delta = totp.validate({ token: code, window: 1 });
+// ...
+const counterDelta = Math.min(delta, 0); // -1 or 0, never +1
+const counter = currentCounter + counterDelta;
+```
+
+`Math.min(delta, 0)` clamps to ≤ 0, so `counter` is always the **current** step or **one step in the past** — never a future step. The `counter <= lastCounter` check in the route is correct and complete. No fix needed.
+
+If anyone revisits this in the future, this analysis is the basis for closing the ticket.
+
+---
+
+## Suggested order for the next sprint
+
+1. **#10 (indexes)** — cheap, high impact, addresses a growing data cliff. Do first.
+2. **#9 (N+1)** — bigger effort but the same root cause family. Tackle after indexes.
+3. **#14 (offer lock)** — small but prevents data loss; fits in a single PR.
+4. **#13 (pagination)** — UX polish; do last, batch with other UX cleanup.
+
+Estimated total: 1-2 days of focused work.

+# Plán prací (Work Schedule) Module Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Build a work-schedule module under Docházka that lets a foreman plan each employee's per-day work as date ranges (with per-day overrides) and lets every employee see the plan read-only. Single new sidebar entry, single page with two permission-driven modes.
+
+**Architecture:** Two new Prisma tables (`work_plan_entries` for ranges, `work_plan_overrides` for single-day exceptions) and one new enum (`plan_category`). Backend is REST under `/api/admin/plan` following the existing `routes → Zod schemas → services → Prisma` pattern, with audit logging on every write. Frontend is a single page (`PlanWork.tsx`) that renders a `PlanGrid` component and a state-driven `PlanCellModal` (edit) or `PlanCellDetailModal` (view-only), reusing `FormModal`, `FormField`, `ConfirmModal`, `AdminDatePicker`. Sidebar entry gated by `attendance.manage || attendance.record`; page itself decides editor vs read-only mode by checking `useAuth().hasPermission('attendance.manage')`.
+
+**Tech Stack:** Prisma 6.19.2 (MySQL), Fastify 5, Zod 4, React 18 + Vite, TanStack React Query, Vitest + Supertest for backend tests.
+
+**Reference spec:** `docs/superpowers/specs/2026-06-05-plan-praci-design.md`

+
+## Phase 0: Verification Prerequisite
+
+Before starting, confirm the developer is on a clean working tree on `master` and that the dev server is **not** running (per `CLAUDE.md`, the user manages the dev server — do not start it):
+
+```bash
+git status
+# Expected: working tree clean OR only the spec file from brainstorming
+
+pgrep -f "tsx watch src/server.ts" || echo "dev server not running (good)"
+```
+
+If the dev server is running, **stop here** and ask the user to stop it. Database migrations can conflict with active connections.
+
+---
+
+## Phase 1: Database Foundation
+
+### Task 1: Add Prisma Enum and Models
+
+**Files:**
+
+- Modify: `prisma/schema.prisma`
+
+- [ ] **Step 1: Add the `plan_category` enum**
+
+Open `prisma/schema.prisma` and find the enums section. The current schema has these enums: `attendance_leave_type`. Append the new enum at the end of the enums block (search for the last `enum` declaration and add after it):
+
+```prisma
+enum plan_category {
+  work
+  preparation
+  travel
+  leave
+  sick
+  training
+  other
+}
+```
+
+- [ ] **Step 2: Add the `work_plan_entries` model**
+
+Append the following model at the end of `prisma/schema.prisma` (after the last existing model):
+
+```prisma
+model work_plan_entries {
+  id         Int             @id @default(autoincrement())
+  user_id    Int
+  date_from  DateTime        @db.Date
+  date_to    DateTime        @db.Date
+  project_id Int?
+  category   plan_category   @default(work)
+  note       String          @db.VarChar(500)
+  created_by Int
+  created_at DateTime?       @default(now()) @db.Timestamp(0)
+  updated_at DateTime?       @default(now()) @db.Timestamp(0)
+  is_deleted Boolean?        @default(false)
+  users      users           @relation(fields: [user_id], references: [id], onDelete: Cascade, onUpdate: NoAction)
+  projects   projects?       @relation(fields: [project_id], references: [id], onDelete: SetNull, onUpdate: NoAction)
+  creator    users           @relation("work_plan_entries_creator", fields: [created_by], references: [id], onDelete: Restrict, onUpdate: NoAction)
+
+  @@index([user_id, date_from], map: "idx_wpe_user_from")
+  @@index([user_id, date_to], map: "idx_wpe_user_to")
+  @@index([project_id], map: "idx_wpe_project")
+  @@index([date_from, date_to], map: "idx_wpe_dates")
+}
+```
+
+- [ ] **Step 3: Add the `work_plan_overrides` model**
+
+Append immediately after `work_plan_entries`:
+
+```prisma
+model work_plan_overrides {
+  id         Int           @id @default(autoincrement())
+  user_id    Int
+  shift_date DateTime      @db.Date
+  project_id Int?
+  category   plan_category
+  note       String        @db.VarChar(500)
+  created_by Int
+  created_at DateTime?     @default(now()) @db.Timestamp(0)
+  updated_at DateTime?     @default(now()) @db.Timestamp(0)
+  is_deleted Boolean?      @default(false)
+  users      users         @relation(fields: [user_id], references: [id], onDelete: Cascade, onUpdate: NoAction)
+  projects   projects?     @relation(fields: [project_id], references: [id], onDelete: SetNull, onUpdate: NoAction)
+  creator    users         @relation("work_plan_overrides_creator", fields: [created_by], references: [id], onDelete: Restrict, onUpdate: NoAction)
+
+  @@unique([user_id, shift_date], map: "uniq_wpo_user_date")
+  @@index([shift_date], map: "idx_wpo_date")
+}
+```
+
+- [ ] **Step 4: Add the back-relations on the `users` and `projects` models**
+
+Open `prisma/schema.prisma` and find the `model users` block. Add these relation fields to its existing relation list (place them adjacent to the other work-related relations, or at the end of the relations list — Prisma does not care about order):
+
+```prisma
+  work_plan_entries        work_plan_entries[]         @relation("work_plan_entries_creator")
+  work_plan_entries_owned  work_plan_entries[]         // entries where this user is the employee
+  work_plan_overrides      work_plan_overrides[]       @relation("work_plan_overrides_creator")
+  work_plan_overrides_owned work_plan_overrides[]      // overrides where this user is the employee
+```
+
+Find the `model projects` block. Add this relation field to its existing relations:
+
+```prisma
+  work_plan_entries   work_plan_entries[]
+  work_plan_overrides work_plan_overrides[]
+```
+
+- [ ] **Step 5: Generate and apply the migration**
+
+```bash
+npx prisma migrate dev --name add_work_plan
+```
+
+Expected: a new folder `prisma/migrations/<timestamp>_add_work_plan/` is created with a `migration.sql` containing `CREATE TABLE work_plan_entries`, `CREATE TABLE work_plan_overrides`, and the enum. The Prisma client is regenerated.
+
+If Prisma complains about missing/dangling relations, re-read the existing `users` and `projects` models and ensure the relation names match exactly.
+
+- [ ] **Step 6: Verify the schema is valid**
+
+```bash
+npx prisma generate
+npx tsc -p tsconfig.server.json --noEmit
+```
+
+Expected: no TypeScript errors. If `tsc` complains about the new `plan_category` type, the next task will introduce the import.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add prisma/schema.prisma prisma/migrations/
+git commit -m "feat(plan): add work_plan_entries, work_plan_overrides, plan_category enum"
+```

+### Task 2: Zod Schemas
+
+**Files:**
+
+- Create: `src/schemas/plan.schema.ts`
+
+- [ ] **Step 1: Write the schema file**
+
+Create `src/schemas/plan.schema.ts` with the following content:

+> **Note on Prisma input types:** the `category: input.category as any` cast avoids having to import the Prisma enum at runtime. The Zod schema already constrains the value to a valid enum member, so the cast is safe. If your team prefers strict types, replace with `category: input.category as keyof typeof plan_category` after importing the enum from `@prisma/client`.

+### Task 14: Grid Component
+
+**Files:**
+
+- Create: `src/admin/components/PlanGrid.tsx`
+- Create: `src/admin/components/PlanRangeChips.tsx`
+- Create: `src/admin/plan.css` (or merge into `attendance.css` — see Step 0)
+
+- [ ] **Step 0: Decide where the CSS lives**
+
+Open `src/admin/attendance.css` and add a comment header: `/* === Plán prací (work schedule) module === */`. If the file is already large (>1000 lines), create a separate `src/admin/plan.css` instead. **Pick one** and stick with it. The rest of this plan assumes `src/admin/plan.css`.
+
+- [ ] **Step 1: Add the CSS file**
+
+Create `src/admin/plan.css`:

+}
+```
+
+- [ ] **Step 2: Lazy-load and route the page**
+
+Open `src/admin/AdminApp.tsx`. Find the line `const AttendanceLocation = lazy(() => import("./pages/AttendanceLocation"));`. Add the PlanWork import after the AttendanceLocation lazy import (in the "Docházka" group):
+
+```typescript
+const PlanWork = lazy(() => import("./pages/PlanWork"));
+```
+
+Find the line `<Route path="attendance/location/:id" element={<AttendanceLocation />} />`. Add the new route after it:
+
+```typescript
+              <Route path="attendance/plan" element={<PlanWork />} />
+```
+
+Find the line `import "./attendance.css";`. Add the plan CSS import immediately after it:
+
+```typescript
+import "./plan.css";
+```
+
+- [ ] **Step 3: Add the sidebar entry**
+
+Open `src/admin/components/Sidebar.tsx`. Find the "Docházka" section. Add a new menu item after the "Správa bilancí" item (the last one in the section, just before the closing `]`):
+
+```typescript
+      {
+        path: "/attendance/plan",
+        label: "Plán prací",
+        permission: ["attendance.manage", "attendance.record"],
+        icon: (
+          <svg
+            viewBox="0 0 24 24"
+            fill="none"
+            stroke="currentColor"
+            strokeWidth="2"
+          >
+            <rect x="3" y="4" width="18" height="18" rx="2" />
+            <line x1="16" y1="2" x2="16" y2="6" />
+            <line x1="8" y1="2" x2="8" y2="6" />
+            <line x1="3" y1="10" x2="21" y2="10" />
+            <rect x="7" y="14" width="3" height="3" />
+            <rect x="14" y="14" width="3" height="3" />
+          </svg>
+        ),
+      },
+```
+
+- [ ] **Step 4: Verify the frontend compiles**
+
+```bash
+npx tsc -p tsconfig.json --noEmit
+```
+
+Expected: no errors. The first run may surface small prop mismatches with `FormModal`, `ConfirmModal`, or `AdminDatePicker` — adjust the modal file to match the actual API.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/admin/pages/PlanWork.tsx src/admin/AdminApp.tsx src/admin/components/Sidebar.tsx
+git commit -m "feat(plan): page, route, sidebar entry, CSS import"
+```
+
+---
+
+### Task 17: Manual Smoke Test
+
+**Files:** none (no code changes expected).
+
+- [ ] **Step 1: Build the production bundle**
+
+```bash
+npm run build
+```
+
+Expected: no errors. If the build fails, fix the issues before continuing.
+
+- [ ] **Step 2: Start the dev server (manual)**
+
+**Per `CLAUDE.md`, the user manages the dev server. Ask the user to start it:**
+
+> The frontend and backend are wired. Could you start the dev server so I can verify the page renders and the grid loads? (`npm run dev` or your usual workflow.)
+
+Wait for the user to confirm it's running.
+
+- [ ] **Step 3: Smoke test checklist**
+
+Manually verify in the browser:
+
+1. Log in as an admin user. Open Docházka → Plán prací. The page should render with a week view grid.
+2. Click an empty cell. The edit modal should open with default values.
+3. Fill in a project, category "Práce", and a note. Submit. The cell should now show a chip with the project and note.
+4. Click the same cell. The "Den je součástí rozsahu" chooser should appear. Click "Upravit pouze tento den" — the override form opens.
+5. Switch to month view via the toggle. The grid should reload with a month of dates.
+6. Log out, log in as a regular employee (with `attendance.record` only). The page should render in read-only mode: cells are non-clickable for editing, and clicking a populated cell opens a view-only detail modal.
+7. Check the audit log: open Nastavení → Audit log, search for `work_plan_entry` or `work_plan_override` entity_type. The mutations from step 3 should appear.
+
+- [ ] **Step 4: Commit any smoke-test fixes**
+
+If anything had to be fixed during the smoke test, commit them individually with clear messages:
+
+```bash
+git add -A
+git commit -m "fix(plan): <describe the issue>"
+```
+
+---
+
+## Phase 5: Release Preparation
+
+### Task 18: Bump Version, Build, and Tag
+
+**Files:**
+
+- Modify: `package.json` (manual version bump)
+
+- [ ] **Step 1: Bump the version in `package.json`**
+
+Open `package.json`. Find the `"version"` field. Bump the minor version (e.g. `1.8.0` → `1.9.0`). Ask the user which version to use if uncertain.
+
+- [ ] **Step 2: Build**
+
+```bash
+npm run build
+```
+
+Expected: clean build.
+
+- [ ] **Step 3: Commit the version bump**
+
+```bash
+git add package.json
+git commit -m "chore(release): bump version to <new-version>"
+git tag -a v<new-version> -m "Plán prací module"
+```
+
+**Do not push.** The release push + tarball + deploy to production is the user's responsibility per the project's release process (`CLAUDE.md` "Release Process" section).
+
+- [ ] **Step 4: Hand off to the user**
+
+Tell the user:
+
+> The plan module is complete. All backend tests pass (`npm test`), the production build is clean (`npm run build`), and the manual smoke test passed. The release artifacts are ready.
+>
+> Per the project's release process (`CLAUDE.md`), the next steps are yours:
+>
+> 1. Push to Gitea: `git push origin master && git push origin v<new-version>`
+> 2. Create the tarball: `tar -czf app-ts-<new-version>.tar.gz dist dist-client prisma package.json package-lock.json scripts`
+> 3. Deploy via SSH: `scp` to `boha_admin@192.168.50.100:/tmp/`, extract to `/var/www/app-ts`, run `npm install --omit=dev`, `npx prisma migrate deploy`, `pm2 restart app-ts --update-env`
+> 4. Smoke-test on production: log in, open Docházka → Plán prací, add a one-day entry, reload, confirm it shows.
+
+---
+
+## Self-Review Notes (for the plan author)
+
+- **Spec coverage:** all 9 spec sections (Core, Effective-cell resolution, Editing rules, Categories, Visibility & permissions, Grid, Audit, Non-goals, Architecture) have at least one implementing task. The new enum is in Task 1, the two new tables in Task 1, the data model in Task 1, the effective-cell resolution in Task 3 (service) and Task 4 (grid), the past-date lock in Task 6, CRUD in Tasks 7–8, list in Task 9, routes in Task 10, server wiring in Task 11, frontend state in Task 13, grid in Task 14, edit modal in Task 15, page in Task 16, smoke test in Task 17, release in Task 18.
+- **Placeholder scan:** no "TBD" / "TODO" in the task steps. All "Check" notes in steps 13.1, 15.1, 15.2, 16.4 reference existing files the implementer will read and adjust to — they are not placeholders.
+- **Type consistency:** the service exports `resolveCell`, `resolveGrid`, `listPlanUsers`, `assertNotPastDate`, `createEntry`, `updateEntry`, `deleteEntry`, `createOverride`, `updateOverride`, `deleteOverride`, `listEntries`, `listOverrides` — these are imported consistently in the route file (Task 10) and the test file. The frontend `ResolvedCell`, `PlanUser`, `GridData` types are defined in `src/admin/lib/queries/plan.ts` (Task 13.1) and used by `PlanGrid` (Task 14.3), `PlanCellModal` (Task 15.1), and the page (Task 16.1). The modal prop `mode` uses a discriminated union that is referenced consistently.

+# Manual Project & Order Creation — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Let users manually create projects on `/projects` and orders without an offer on `/orders`, reusing the existing shared order/project numbering pool with correct tracking.
+
+**Architecture:** Backend re-introduces `createProject` (removed in `82919d3`) but takes the next _shared_ number via `generateSharedNumber(tx)` inside a transaction; the manual `createOrder` (already exists) gains an optional linked-project. Frontend adds inline create modals on the Projects and Orders list pages, mirroring the `Vehicles.tsx` `FormModal`/`FormField` pattern. `projects.create` permission is re-added via a migration + seed.
+
+**Tech Stack:** Fastify 5, Prisma 6 (MySQL), Zod 4, React 18 + TanStack Query v5, Vitest.
+
+**Spec:** `docs/superpowers/specs/2026-06-06-manual-project-order-creation-design.md`
+
+**Conventions to honor (from CLAUDE.md):**
+
+- Routes: `success()`/`error()`/`parseId()`/`parseBody()`; never raw `reply.send` for new code.
+- `AuthData.roleName` (admin bypasses permission checks).
+- Services return `{ data }`-ish or `{ error, status }`; own Prisma; routes stay thin.
+- Czech user-facing strings, English identifiers.
+- Broad query invalidation (`["projects"]`, not `["projects","list"]`).
+- Numbering: NEVER hardcode — always go through `numbering.service`.

+## Task 1: `createProject` service + schema (TDD)
+
+**Files:**
+
+- Create test: `src/__tests__/manual-create.test.ts`
+- Modify: `src/schemas/projects.schema.ts`
+- Modify: `src/services/projects.service.ts:1-5` (imports) and add `createProject`/`getNextProjectNumber`
+
+- [ ] **Step 1: Write the failing test** — create `src/__tests__/manual-create.test.ts`:
+
+```ts
+import { describe, it, expect, afterEach } from "vitest";
+import prisma from "../config/database";
+import { createProject } from "../services/projects.service";
+
+const createdProjectIds: number[] = [];
+const createdOrderIds: number[] = [];
+
+afterEach(async () => {
+  for (const id of createdProjectIds)
+    await prisma.projects.deleteMany({ where: { id } });
+  for (const id of createdOrderIds)
+    await prisma.orders.deleteMany({ where: { id } });
+  createdProjectIds.length = 0;
+  createdOrderIds.length = 0;
+  await prisma.number_sequences.deleteMany({ where: { type: "shared" } });
+});
+
+describe("createProject (manual, standalone)", () => {
+  it("assigns a shared number and is not linked to an order", async () => {
+    const result = await createProject({
+      name: "Test projekt",
+      status: "aktivni",
+    });
+    expect("project_number" in result).toBe(true);
+    if (!("project_number" in result)) return;
+    createdProjectIds.push(result.id);
+    expect(typeof result.project_number).toBe("string");
+    expect(result.project_number!.length).toBeGreaterThan(0);
+    expect(result.order_id).toBeNull();
+  });
+
+  it("gives consecutive standalone projects distinct numbers", async () => {
+    const a = await createProject({ name: "Projekt A", status: "aktivni" });
+    const b = await createProject({ name: "Projekt B", status: "aktivni" });
+    if ("project_number" in a) createdProjectIds.push(a.id);
+    if ("project_number" in b) createdProjectIds.push(b.id);
+    expect("project_number" in a && "project_number" in b).toBe(true);
+    if ("project_number" in a && "project_number" in b) {
+      expect(a.project_number).not.toBe(b.project_number);
+    }
+  });
+});
+```
+
+- [ ] **Step 2: Run it and confirm it fails**
+
+Run: `npx vitest run src/__tests__/manual-create.test.ts`
+Expected: FAIL — `createProject` is not exported from `projects.service`.
+
+- [ ] **Step 3: Add `CreateProjectSchema`** to `src/schemas/projects.schema.ts` (above `CreateProjectNoteSchema`). Match the file's existing `z.object` style; add NaN guards on the new number coercions (CLAUDE.md) and treat `""` as null so an empty `<select>` value doesn't become `0`:
+
+```ts
+export const CreateProjectSchema = z.object({
+  name: z.string().min(1, "Zadejte název projektu"),
+  customer_id: z
+    .union([z.number(), z.string(), z.null()])
+    .transform((v) => (v === null || v === "" ? null : Number(v)))
+    .refine((v) => v === null || !Number.isNaN(v), {
+      message: "Neplatný zákazník",
+    })
+    .optional(),
+  responsible_user_id: z
+    .union([z.number(), z.string(), z.null()])
+    .transform((v) => (v === null || v === "" ? null : Number(v)))
+    .refine((v) => v === null || !Number.isNaN(v), {
+      message: "Neplatná zodpovědná osoba",
+    })
+    .optional(),
+  status: z.string().optional().default("aktivni"),
+  start_date: z.union([z.string(), z.null()]).optional(),
+  end_date: z.union([z.string(), z.null()]).optional(),
+  notes: z.string().nullish(),
+});
+```
+
+And add to the type exports at the bottom of the file:
+
+```ts
+export type CreateProjectInput = z.infer<typeof CreateProjectSchema>;
+```
+
+- [ ] **Step 4: Extend the numbering imports** in `src/services/projects.service.ts` — replace the line `import { releaseSharedNumber } from "./numbering.service";` (line 2) with:
+
+```ts
+import {
+  generateSharedNumber,
+  previewSharedNumber,
+  releaseSharedNumber,
+} from "./numbering.service";
+```
+
+Also add the schema type import near the top (after the existing imports):
+
+```ts
+import type { CreateProjectInput } from "../schemas/projects.schema";
+```
+
+- [ ] **Step 5: Implement `createProject` + `getNextProjectNumber`** — add to `src/services/projects.service.ts` (e.g. just above `deleteProject`):
+
+```ts
+/**
+ * Create a standalone (manual) project. Takes the next SHARED number — the
+ * same pool orders/projects draw from — generated atomically inside the
+ * transaction (SELECT … FOR UPDATE via getNextSequence). order_id stays null,
+ * which is what marks it "samostatný" in the UI. NAS folder creation is
+ * best-effort (the manager self-guards isConfigured() and swallows fs errors).
+ */
+export async function createProject(data: CreateProjectInput) {
+  if (data.customer_id != null) {
+    const customer = await prisma.customers.findUnique({
+      where: { id: data.customer_id },
+    });
+    if (!customer) return { error: "Zákazník nenalezen", status: 400 };
+  }
+  if (data.responsible_user_id != null) {
+    const user = await prisma.users.findUnique({
+      where: { id: data.responsible_user_id },
+    });
+    if (!user) return { error: "Zodpovědná osoba nenalezena", status: 400 };
+  }
+
+  const project = await prisma.$transaction(async (tx) => {
+    const project_number = await generateSharedNumber(tx);
+    return tx.projects.create({
+      data: {
+        project_number,
+        name: data.name,
+        customer_id: data.customer_id ?? null,
+        responsible_user_id: data.responsible_user_id ?? null,
+        status: data.status || "aktivni",
+        start_date: data.start_date ? new Date(data.start_date) : null,
+        end_date: data.end_date ? new Date(data.end_date) : null,
+        notes: data.notes ?? null,
+        order_id: null,
+        quotation_id: null,
+      },
+    });
+  });
+
+  if (project.project_number && nasFileManager.isConfigured()) {
+    nasFileManager.createProjectFolder(
+      project.project_number,
+      project.name || "",
+    );
+  }
+
+  return project;
+}
+
+/** Preview the next shared number for the create form (does NOT consume it). */
+export async function getNextProjectNumber(): Promise<string> {
+  return previewSharedNumber();
+}
+```
+
+- [ ] **Step 6: Run the test and confirm it passes**
+
+Run: `npx vitest run src/__tests__/manual-create.test.ts`
+Expected: PASS (2 tests).
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add src/__tests__/manual-create.test.ts src/schemas/projects.schema.ts src/services/projects.service.ts
+git commit -m "feat(projects): add createProject service (manual, shared numbering)"

+
+## Task 2: Project routes (`POST /`, `GET /next-number`)
+
+**Files:**
+
+- Modify: `src/routes/admin/projects.ts`
+
+- [ ] **Step 1: Import the new schema + service functions** — update the two import blocks at the top of `src/routes/admin/projects.ts`:
+
+```ts
+import {
+  UpdateProjectSchema,
+  CreateProjectSchema,
+  CreateProjectNoteSchema,
+} from "../../schemas/projects.schema";
+import {
+  listProjects,
+  getProject,
+  createProject,
+  getNextProjectNumber,
+  updateProject,
+  deleteProject,
+  createProjectNote,
+  deleteProjectNote,
+} from "../../services/projects.service";
+```
+
+- [ ] **Step 2: Add the two routes** — inside `projectsRoutes`, immediately after the `fastify.get("/", …)` list route (before `GET /:id`, so the static `/next-number` path is registered alongside the other statics):
+
+```ts
+// GET /api/admin/projects/next-number — preview the next shared number
+fastify.get(
+  "/next-number",
+  { preHandler: requirePermission("projects.create") },
+  async (_request, reply) => {
+    const number = await getNextProjectNumber();
+    return success(reply, { number, next_number: number });
+  },
+);
+
+// POST /api/admin/projects — create a standalone (manual) project
+fastify.post(
+  "/",
+  { preHandler: requirePermission("projects.create") },
+  async (request, reply) => {
+    const parsed = parseBody(CreateProjectSchema, request.body);
+    if ("error" in parsed) return error(reply, parsed.error, 400);
+
+    const result = await createProject(parsed.data);
+    if ("error" in result)
+      return error(reply, result.error, (result as any).status ?? 400);
+
+    await logAudit({
+      request,
+      authData: request.authData,
+      action: "create",
+      entityType: "project",
+      entityId: result.id,
+      description: `Vytvořen projekt ${result.project_number}`,
+    });
+    return success(reply, { id: result.id }, 201, "Projekt byl vytvořen");
+  },
+);
+```
+
+- [ ] **Step 3: Verify it compiles**
+
+Run: `npm run build:server`
+Expected: builds with no TypeScript errors.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/routes/admin/projects.ts
+git commit -m "feat(projects): POST /projects + GET /projects/next-number"
+```

+
+## Task 3: Manual order — optional linked project (TDD)
+
+**Files:**
+
+- Modify: `src/schemas/orders.schema.ts:49-89` (`CreateOrderSchema`)
+- Modify: `src/services/orders.service.ts:275-291` (`CreateOrderData`) and `293-366` (`createOrder`)
+- Modify: `src/routes/admin/orders.ts:203-225` (manual branch audit)
+- Modify test: `src/__tests__/manual-create.test.ts`
+
+- [ ] **Step 1: Add the failing test** — append a new `describe` block to `src/__tests__/manual-create.test.ts`:
+
+```ts
+import { createOrder } from "../services/orders.service";
+
+const baseOrder = {
+  status: "prijata" as const,
+  currency: "CZK",
+  language: "cs",
+  vat_rate: 21,
+  apply_vat: true,
+  exchange_rate: 1,
+};
+
+describe("createOrder (manual, optional linked project)", () => {
+  it("creates an order AND a project sharing one number when create_project=true", async () => {
+    const res = await createOrder({
+      ...baseOrder,
+      scope_title: "Ruční zakázka",
+      create_project: true,
+    });
+    expect("id" in res).toBe(true);
+    if (!("id" in res)) return;
+    createdOrderIds.push(res.id);
+    expect(res.project_id).toBeTruthy();
+    const project = await prisma.projects.findUnique({
+      where: { id: res.project_id! },
+    });
+    if (project) createdProjectIds.push(project.id);
+    expect(project?.project_number).toBe(res.order_number);
+    expect(project?.order_id).toBe(res.id);
+  });
+
+  it("creates only the order when create_project=false", async () => {
+    const res = await createOrder({ ...baseOrder, create_project: false });
+    expect("id" in res).toBe(true);
+    if (!("id" in res)) return;
+    createdOrderIds.push(res.id);
+    expect(res.project_id).toBeUndefined();
+  });
+});
+
+describe("shared pool coherence (tracking)", () => {
+  it("order → standalone project → order produce three distinct shared numbers", async () => {
+    const o1 = await createOrder({ ...baseOrder, create_project: true });
+    if ("id" in o1) {
+      createdOrderIds.push(o1.id);
+      if (o1.project_id) createdProjectIds.push(o1.project_id);
+    }
+    const p = await createProject({ name: "Mezi-projekt", status: "aktivni" });
+    if ("project_number" in p) createdProjectIds.push(p.id);
+    const o2 = await createOrder({ ...baseOrder, create_project: false });
+    if ("id" in o2) createdOrderIds.push(o2.id);
+
+    const n1 = "id" in o1 ? o1.order_number : null;
+    const np = "project_number" in p ? p.project_number : null;
+    const n2 = "id" in o2 ? o2.order_number : null;
+    expect(new Set([n1, np, n2]).size).toBe(3);
+  });
+});
+```
+
+> Note: `createOrder`'s success return type must include the optional `project_id` (added in Step 4). Until then, this test fails to compile/run — that is the expected red state. The coherence test also needs `createProject` (already imported in Task 1).
+
+- [ ] **Step 2: Run it and confirm it fails**
+
+Run: `npx vitest run src/__tests__/manual-create.test.ts`
+Expected: FAIL — `create_project`/`project_id` don't exist yet.
+
+- [ ] **Step 3: Add `create_project` to `CreateOrderSchema`** — in `src/schemas/orders.schema.ts`, inside `CreateOrderSchema` (after the `sections` field, before the closing `})`):
+
+```ts
+  create_project: z
+    .preprocess((v) => v === true || v === 1 || v === "1", z.boolean())
+    .optional()
+    .default(true),
+```
+
+- [ ] **Step 4: Extend `CreateOrderData` and `createOrder`** — in `src/services/orders.service.ts`:
+
+Add to the `CreateOrderData` interface (after `sections?: OrderSectionInput[];`, line 290):
+
+```ts
+  create_project?: boolean;
+```
+
+In `createOrder`, replace the final `return { id: order.id, order_number: order.order_number };` (the value returned from inside the `prisma.$transaction` callback) with a block that optionally creates the linked project, mirroring `createOrderFromQuotation`'s project block:
+
+```ts
+let projectId: number | undefined;
+// Only auto-create a project for genuine offer-less orders; share the
+// order's number (same shared pool) exactly like the from-quotation flow.
+if (body.create_project !== false && body.quotation_id == null) {
+  const project = await tx.projects.create({
+    data: {
+      project_number: orderNumber,
+      name: body.scope_title || body.customer_order_number || orderNumber,
+      customer_id: order.customer_id,
+      order_id: order.id,
+      status: "aktivni",
+    },
+  });
+  projectId = project.id;
+}
+
+return {
+  id: order.id,
+  order_number: order.order_number,
+  project_id: projectId,
+};
+```
+
+- [ ] **Step 5: Audit the linked project in the route** — in `src/routes/admin/orders.ts`, the manual branch (lines 203-225). After the existing `logAudit` for the order and before the `return success(...)`, add:
+
+```ts
+if (result.project_id) {
+  await logAudit({
+    request,
+    authData: request.authData,
+    action: "create",
+    entityType: "project",
+    entityId: result.project_id,
+    description: `Vytvořen projekt k objednávce ${result.order_number}`,
+  });
+}
+```
+
+> `result.order_number` is already returned by `createOrder` (it's part of the success object); no extra fetch needed.
+
+- [ ] **Step 6: Run the test and confirm it passes**
+
+Run: `npx vitest run src/__tests__/manual-create.test.ts`
+Expected: PASS (all 4 tests).
+
+- [ ] **Step 7: Commit**
+
+```bash

+## Task 4: `projects.create` permission (migration + seed)
+
+**Files:**
+
+- Create: `prisma/migrations/20260606120000_add_projects_create_permission/migration.sql`
+- Modify: `prisma/seed.ts` (PERMISSIONS array, projects block ~lines 168-192)
+
+> ⚠️ Verify `20260606120000` sorts AFTER the latest existing migration folder (`ls prisma/migrations`). If a later timestamp exists, bump the prefix so this is last.
+
+- [ ] **Step 1: Create the migration** — `prisma/migrations/20260606120000_add_projects_create_permission/migration.sql`:
+
+```sql
+-- Re-add the projects.create permission (removed in commit 82919d3 when manual
+-- project creation was deleted). Idempotent: re-running is a no-op.
+-- Mirrors prisma/seed.ts PERMISSIONS exactly (name, display_name, module, description).
+
+-- 1. Insert the permission (INSERT IGNORE skips on duplicate name).
+INSERT IGNORE INTO `permissions` (`name`, `display_name`, `module`, `description`, `created_at`) VALUES
+  ('projects.create', 'Vytvořit projekt', 'projects', 'Ručně vytvářet projekty', NOW());
+
+-- 2. Grant it to the admin role (idempotent via composite PK).
+INSERT IGNORE INTO `role_permissions` (`role_id`, `permission_id`)
+SELECT r.id, p.id
+FROM   `roles` r
+CROSS  JOIN `permissions` p
+WHERE  r.name = 'admin'
+  AND  p.name IN ('projects.create');
+```
+
+- [ ] **Step 2: Add to seed.ts** — in `prisma/seed.ts`, inside the `PERMISSIONS` array's `// Projekty` block, add (e.g. after `projects.view`):
+
+```ts
+  {
+    name: "projects.create",
+    display_name: "Vytvořit projekt",
+    module: "projects",
+    description: "Ručně vytvářet projekty",
+  },
+```
+
+- [ ] **Step 3: Apply to the dev DB.** Ask the user to confirm before touching the database, then:
+
+Run: `npx prisma migrate deploy`
+Expected: applies `20260606120000_add_projects_create_permission`. (`migrate deploy` only runs pending migrations and needs no shadow DB; admin already bypasses permission checks, so this mainly matters for non-admin roles and prod.)

+```bash
+git add src/admin/lib/queries/projects.ts src/admin/lib/queries/orders.ts
+git commit -m "feat(queries): next-number options for project/order create modals"
+```
+
+---
+
+## Task 6: Projects page — create modal, badge, empty-state
+
+**Files:**
+
+- Modify: `src/admin/pages/Projects.tsx`
+
+This mirrors the `Vehicles.tsx` inline create-modal pattern (state + `useApiMutation` + `handleSubmit` + `FormModal`/`FormField`).
+
+- [ ] **Step 1: Add imports** — extend the import block at the top of `src/admin/pages/Projects.tsx`:
+
+```ts
+import { useQuery } from "@tanstack/react-query";
+import FormModal from "../components/FormModal";
+import FormField from "../components/FormField";
+import {
+  projectListOptions,
+  projectNextNumberOptions,
+} from "../lib/queries/projects";
+import { offerCustomersOptions } from "../lib/queries/offers";
+import { userListOptions } from "../lib/queries/users";
+```
+
+(Remove the now-duplicated single `projectListOptions` import line so it isn't imported twice.)
+
+- [ ] **Step 2: Add create-modal state + mutation + submit** — inside the `Projects()` component, after the existing `deleteMutation` block:
+
+```ts
+const [showCreate, setShowCreate] = useState(false);
+const [createForm, setCreateForm] = useState({
+  name: "",
+  customer_id: "",
+  responsible_user_id: "",
+  status: "aktivni",
+  start_date: "",
+  end_date: "",
+  notes: "",
+});
+const [createErrors, setCreateErrors] = useState<Record<string, string>>({});
+const [creating, setCreating] = useState(false);
+
+const customersQuery = useQuery({
+  ...offerCustomersOptions(),
+  enabled: showCreate,
+});
+const usersQuery = useQuery({ ...userListOptions(), enabled: showCreate });
+const nextNumberQuery = useQuery({
+  ...projectNextNumberOptions(),
+  enabled: showCreate,
+});
+
+const createMutation = useApiMutation<typeof createForm, { id: number }>({
+  url: () => `${API_BASE}/projects`,
+  method: () => "POST",
+  invalidate: ["projects", "orders", "offers", "invoices", "attendance"],
+  onSuccess: () => {
+    setShowCreate(false);
+    alert.success("Projekt byl vytvořen");
+  },
+});
+
+const openCreate = () => {
+  setCreateForm({
+    name: "",
+    customer_id: "",
+    responsible_user_id: "",
+    status: "aktivni",
+    start_date: "",
+    end_date: "",
+    notes: "",
+  });
+  setCreateErrors({});
+  setShowCreate(true);
+};
+
+const handleCreate = async () => {
+  const errs: Record<string, string> = {};
+  if (!createForm.name.trim()) errs.name = "Zadejte název projektu";
+  setCreateErrors(errs);
+  if (Object.keys(errs).length > 0) return;
+
+  setCreating(true);
+  try {
+    await createMutation.mutateAsync(createForm);
+  } catch (e) {
+    alert.error(e instanceof Error ? e.message : "Chyba připojení");
+  } finally {
+    setCreating(false);
+  }
+};
+```
+
+- [ ] **Step 3: Add the header button** — replace the page-header `<div>` (the one holding only the title/subtitle, ~lines 117-128) so it gains an actions slot gated by `projects.create`:
+
+```tsx
+<div>
+  <h1 className="admin-page-title">Projekty</h1>
+  <p className="admin-page-subtitle">
+    {pagination?.total ?? projects.length}{" "}
+    {czechPlural(
+      pagination?.total ?? projects.length,
+      "projekt",
+      "projekty",
+      "projektů",
+    )}
+  </p>
+</div>;
+{
+  hasPermission("projects.create") && (
+    <div className="admin-page-actions">
+      <button onClick={openCreate} className="admin-btn admin-btn-primary">
+        <svg
+          width="20"
+          height="20"
+          viewBox="0 0 24 24"
+          fill="none"
+          stroke="currentColor"
+          strokeWidth="2"
+        >
+          <line x1="12" y1="5" x2="12" y2="19" />
+          <line x1="5" y1="12" x2="19" y2="12" />
+        </svg>
+        Přidat projekt
+      </button>
+    </div>
+  );
+}
+```
+
+- [ ] **Step 4: Update the empty-state copy** — change the second `<p>` in the empty state (currently "Projekt se vytvoří automaticky při vytvoření objednávky.") to:
+
+```tsx
+                Projekty vznikají z objednávek nebo je můžete vytvořit ručně
+                tlačítkem „Přidat projekt“.
+```
+
+- [ ] **Step 5: Add the "Typ" badge column** — in `<thead>`, add a header after the `Stav` `<th>`:
+
+```tsx
+<th>Typ</th>
+```
+
+In `<tbody>`, add a matching cell after the `Stav` cell (the `<td>` with the status badge):
+
+```tsx
+<td>
+  <span className="admin-badge">
+    {p.order_id ? "Z objednávky" : "Samostatný"}
+  </span>
+</td>
+```
+
+- [ ] **Step 6: Render the create modal** — just before the closing `</div>` of the component's returned JSX (next to the existing `ConfirmModal`), add the modal. Customer + responsible-user are `<select>`s populated from the queries; the number preview is read-only:
+
+```tsx
+<FormModal
+  isOpen={showCreate}
+  onClose={() => setShowCreate(false)}
+  onSubmit={handleCreate}
+  title="Přidat projekt"
+  submitLabel="Vytvořit"
+  loading={creating}
+>
+  <div className="admin-form">
+    <FormField label="Název" error={createErrors.name} required>
+      <input
+        type="text"
+        value={createForm.name}
+        onChange={(e) => {
+          setCreateForm({ ...createForm, name: e.target.value });
+          setCreateErrors((p) => ({ ...p, name: "" }));
+        }}
+        className="admin-form-input"
+        placeholder="Název projektu"
+        aria-invalid={!!createErrors.name}
+      />
+    </FormField>
+
+    <div className="admin-form-row">
+      <FormField label="Zákazník">
+        <select

+- [ ] **Step 7: Verify build + types**
+
+Run: `npm run build:client`
+Expected: builds clean (no TS errors). Visually confirm later in the running app.
+
+- [ ] **Step 8: Commit**
+
+```bash
+git add src/admin/pages/Projects.tsx
+git commit -m "feat(projects-ui): add project create modal, type badge, empty-state copy"
+```
+
+---
+
+## Task 7: Orders page — manual create modal (header only)
+
+**Files:**
+
+- Modify: `src/admin/pages/Orders.tsx`
+
+- [ ] **Step 1: Add imports** — extend the top of `src/admin/pages/Orders.tsx`:
+
+```ts
+import { useQuery } from "@tanstack/react-query";
+import FormModal from "../components/FormModal";
+import FormField from "../components/FormField";
+import {
+  orderListOptions,
+  orderNextNumberOptions,
+} from "../lib/queries/orders";
+import { offerCustomersOptions } from "../lib/queries/offers";
+```
+
+(Remove the duplicated single `orderListOptions` import line.)
+
+- [ ] **Step 2: Add state + mutation + submit** — inside `Orders()`, after the existing `deleteMutation`:
+
+```ts
+const [showCreate, setShowCreate] = useState(false);
+const [createForm, setCreateForm] = useState({
+  customer_id: "",
+  customer_order_number: "",
+  currency: "CZK",
+  vat_rate: "21",

+const customersQuery = useQuery({
+  ...offerCustomersOptions(),
+  enabled: showCreate,
+});
+const nextNumberQuery = useQuery({
+  ...orderNextNumberOptions(),
+  enabled: showCreate,
+});
+
+// The payload normalises customer_id: "" → null. CreateOrderSchema's
+// customer_id coercion does NOT special-case "", so a raw "" would become
+// Number("") = 0 and hit a foreign-key violation. (Note: the projects schema
+// in Task 1 DOES special-case "", so the project modal can send createForm raw.)
+type OrderCreatePayload = Omit<typeof createForm, "customer_id"> & {
+  customer_id: number | null;
+};
+
+const createMutation = useApiMutation<OrderCreatePayload, { id: number }>({
+  url: () => `${API_BASE}/orders`,
+  method: () => "POST",
+  invalidate: ["orders", "projects", "offers", "invoices"],
+  onSuccess: () => {
+    setShowCreate(false);

+};
+
+const handleCreate = async () => {
+  setCreating(true);
+  try {
+    await createMutation.mutateAsync({
+      ...createForm,
+      customer_id: createForm.customer_id
+        ? Number(createForm.customer_id)

+    });
+  } catch (e) {
+    alert.error(e instanceof Error ? e.message : "Chyba připojení");
+  } finally {
+    setCreating(false);
+  }
+};
+```
+
+- [ ] **Step 3: Add the header button** — in the page-header `motion.div` (lines 105-123), after the title/subtitle `<div>`, add:
+
+```tsx
+{
+  hasPermission("orders.create") && (
+    <div className="admin-page-actions">
+      <button onClick={openCreate} className="admin-btn admin-btn-primary">

+
+---
+
+## Task 8: Full verification
+
+**Files:** none (verification only)
+
+- [ ] **Step 1: Type-check + build everything**
+
+Run: `npm run build`
+Expected: server + client build with zero TypeScript errors.
+
+- [ ] **Step 2: Run the whole test suite**
+
+Run: `npm test`
+Expected: all tests pass (the prior 134 + the 4 new `manual-create` tests = 138).
+
+- [ ] **Step 3: Manual smoke (in the running app — user-driven, do not start the dev server yourself)**
+
+Confirm in the browser:
+
+- `/projects` → "Přidat projekt" creates a standalone project; it appears with a "Samostatný" badge and an auto-assigned number; the audit log shows a `project` create entry.
+- `/orders` → "Vytvořit objednávku" with the checkbox on creates an order **and** a linked project sharing the same number; the project shows "Z objednávky".
+- Creating with the checkbox off makes only the order.
+
+- [ ] **Step 4: Final commit (if any verification fixups were needed)**
+
+```bash
+git add -A
+git commit -m "test: verify manual project/order creation end-to-end"
+```
+
+---
+
+## Notes for the executor
+
+- **Do not start the dev server** (the user manages it). For the Task 4 migration, ask the user to confirm before `prisma migrate deploy`.
+- Admin bypasses permission checks, so the new routes work for admin even before Task 4; the migration matters for non-admin roles and production.
+- Numbering is the sensitive part: the project/order share one `shared` pool. The tracking guarantees (collision check across both tables, release-on-delete, audit, the "Samostatný/Z objednávky" badge) are what make standalone projects coherent — do not bypass `generateSharedNumber`/`previewSharedNumber`.
+- Release is automatic on delete (`deleteProject`/`deleteOrder` already call `releaseSharedNumber`); no new release code is needed.

+# Plan Categories Management Implementation Plan

+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Let `attendance.manage` users create, rename, recolor, and retire work-plan categories via a "Správa kategorií" modal above the calendar, replacing the hardcoded `plan_category` enum and CSS colors with database-driven categories.
+
+**Architecture:** New `plan_categories` table (id, key, label, color, sort_order, is_active). Entry/override `category` columns become `VARCHAR(50)` storing the category **key** (existing values preserved). "Remove" = deactivate. The frontend loads categories via React Query and renders chip/tape colors from an inline `--cat-color` custom property instead of per-key CSS rules.
+
+**Tech Stack:** Prisma 6 → MySQL, Fastify 5, Zod 4, React 18 + TanStack Query, Vitest (real test DB).
+
+**Reference spec:** `docs/superpowers/specs/2026-06-06-plan-categories-management-design.md`
+
+> **Formatting note:** a markdown formatter reflowed some fenced `tsx` blocks.
+> Single-line JSX-prop snippets may render as an assignment, e.g.
+> `categories = { categories };` — read this as "add the JSX prop
+> `categories={categories}` to the named element." Likewise a lone
+> `{ list.map(...) }` shown with a trailing `;` is a JSX expression, not a
+> statement. The larger multi-line code blocks (service, schema, modal
+> component, CSS) are correct as-is.

+## File Structure
+
+- Create `src/schemas/planCategory.schema.ts` — Zod schemas for category CRUD.
+- Create `src/services/planCategory.service.ts` — category CRUD + key validation.
+- Create `src/__tests__/planCategory.test.ts` — service tests (real DB).
+- Create `src/admin/components/PlanCategoriesModal.tsx` — management modal.
+- Modify `prisma/schema.prisma` — add model, change `category` columns, drop enum.
+- Modify `src/types/index.ts` — add `plan_category` to `EntityType`.
+- Modify `src/routes/admin/plan.ts` — category routes + entry/override category validation passthrough.
+- Modify `src/services/plan.service.ts` — validate active category key on entry/override writes; resolve category label for audit.
+- Modify `src/utils/planAuditDescription.ts` + `src/__tests__/planAuditDescription.test.ts` — `buildPlanAuditDescription` takes a resolved `categoryLabel`.
+- Modify `src/schemas/plan.schema.ts` — `category` becomes a non-empty string (not the enum).
+- Modify `src/admin/lib/queries/plan.ts` — `PlanCategory` type, `planCategoriesOptions`, `categoryMap`, `planCategoryLabel(key, map)`.
+- Modify `src/admin/plan.css` — generic `--cat-color` chip/tape rules (delete 14 per-key rules).
+- Modify `src/admin/components/PlanGrid.tsx` — set `--cat-color`, pass label to chips.
+- Modify `src/admin/components/PlanRangeChips.tsx` — render label from prop.
+- Modify `src/admin/components/PlanCellModal.tsx` — category `<select>` + view label from categories.
+- Modify `src/admin/pages/PlanWork.tsx` — load categories, pass down, add button + modal.
+- Modify `src/admin/pages/AuditLog.tsx` + `src/admin/utils/dashboardHelpers.ts` — `plan_category` label.

+
+## Task 1: Database — `plan_categories` table, enum → varchar, seed
+
+**Files:**
+
+- Modify: `prisma/schema.prisma`
+- Create: `prisma/migrations/<timestamp>_plan_categories/migration.sql` (generated, then hand-edited)
+
+⚠️ This task changes the DB. Per CLAUDE.md, **ask the user to stop the dev server and confirm** before running `prisma migrate dev`.
+
+- [ ] **Step 1: Add the model and change the columns in `prisma/schema.prisma`**
+
+Add this model (anywhere among the models):
+
+```prisma
+model plan_categories {
+  id         Int       @id @default(autoincrement())
+  key        String    @unique @db.VarChar(50)
+  label      String    @db.VarChar(100)
+  color      String    @db.VarChar(7)
+  sort_order Int       @default(0)
+  is_active  Boolean   @default(true)
+  created_at DateTime? @default(now()) @db.DateTime(0)
+  updated_at DateTime? @default(now()) @updatedAt @db.DateTime(0)
+}
+```
+
+In `model work_plan_entries`, change:
+
+```prisma
+  category   plan_category   @default(work)
+```
+
+to:
+
+```prisma
+  category   String          @default("work") @db.VarChar(50)
+```
+
+In `model work_plan_overrides`, change:
+
+```prisma
+  category   plan_category
+```
+
+to:
+
+```prisma
+  category   String        @db.VarChar(50)
+```
+
+Delete the enum block:
+
+```prisma
+enum plan_category {
+  work
+  preparation
+  travel
+  leave
+  sick
+  training
+  other
+}
+```
+
+- [ ] **Step 2: Generate the migration WITHOUT applying it**
+
+Run: `npx prisma migrate dev --create-only --name plan_categories`
+Expected: creates `prisma/migrations/<timestamp>_plan_categories/migration.sql` with the CREATE TABLE + the two MODIFY column statements. Nothing applied yet.
+
+- [ ] **Step 3: Append the seed INSERT to the generated `migration.sql`**
+
+Open the new `migration.sql` and add this at the END (after the generated DDL):
+
+```sql
+-- Seed the categories that were previously the plan_category enum
+INSERT INTO `plan_categories` (`key`, `label`, `color`, `sort_order`, `is_active`) VALUES
+  ('work',        'Práce',          '#2563eb', 1, true),
+  ('preparation', 'Příprava',       '#0d9488', 2, true),
+  ('travel',      'Cesta / Montáž', '#ca8a04', 3, true),
+  ('leave',       'Dovolená',       '#16a34a', 4, true),
+  ('sick',        'Nemoc',          '#dc2626', 5, true),
+  ('training',    'Školení',        '#7c3aed', 6, true),
+  ('other',       'Jiné',           '#6b7280', 7, true);
+```
+
+Verify the generated DDL changed the columns to `VARCHAR(50)` (MySQL `MODIFY`). If Prisma emitted `DROP`/recreate that would lose data — it should only `MODIFY`. If unsure, stop and inspect.
+
+- [ ] **Step 4: Ask the user to stop the dev server, then apply**
+
+Confirm with the user. Then run: `npx prisma migrate dev`
+Expected: "All migrations have been applied" and the seed rows inserted.
+
+- [ ] **Step 5: Regenerate the Prisma client**
+
+Run: `npx prisma generate`
+Expected: client regenerated (now `prisma.plan_categories` exists; `category` is `string`).
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add prisma/schema.prisma prisma/migrations
+git commit -m "feat(plan): add plan_categories table, migrate category enum to varchar"
+```
+
+---
+
+## Task 2: Zod schemas for category CRUD
+
+**Files:**
+
+- Create: `src/schemas/planCategory.schema.ts`
+
+- [ ] **Step 1: Create the schema file**
+
+```typescript
+import { z } from "zod";
+
+const hexColor = z
+  .string()
+  .regex(/^#[0-9a-fA-F]{6}$/, "Barva musí být ve formátu #RRGGBB");
+
+export const CreatePlanCategorySchema = z.object({
+  label: z
+    .string()
+    .trim()
+    .min(1, "Název je povinný")
+    .max(100, "Maximálně 100 znaků"),
+  color: hexColor,
+});
+
+export const UpdatePlanCategorySchema = z
+  .object({
+    label: z.string().trim().min(1, "Název je povinný").max(100).optional(),
+    color: hexColor.optional(),
+    is_active: z.boolean().optional(),
+  })
+  .refine((v) => Object.keys(v).length > 0, {
+    message: "Nic k aktualizaci",
+  });
+
+export type CreatePlanCategoryInput = z.infer<typeof CreatePlanCategorySchema>;
+export type UpdatePlanCategoryInput = z.infer<typeof UpdatePlanCategorySchema>;
+```
+
+- [ ] **Step 2: Commit**
+
+```bash
+git add src/schemas/planCategory.schema.ts
+git commit -m "feat(plan): add plan category zod schemas"

+## Task 4: Category routes + audit + EntityType
+
+**Files:**
+
+- Modify: `src/types/index.ts` (add `plan_category`)
+- Modify: `src/routes/admin/plan.ts`
+
+- [ ] **Step 1: Add the entity type**
+
+In `src/types/index.ts`, in the `EntityType` union, after `"work_plan_override";` change the end to:
+
+```typescript
+  | "work_plan_override"
+  | "plan_category";
+```
+
+- [ ] **Step 2: Add imports and routes in `src/routes/admin/plan.ts`**
+
+Add to the imports at the top:

+  UpdatePlanCategorySchema,
+} from "../../schemas/planCategory.schema";
+import {
+  listPlanCategories,

+
+## Task 5: Dynamic category validation on entries/overrides + audit label
+
+**Files:**
+
+- Modify: `src/schemas/plan.schema.ts`
+- Modify: `src/utils/planAuditDescription.ts`
+- Modify: `src/__tests__/planAuditDescription.test.ts`
+- Modify: `src/services/plan.service.ts`
+
+- [ ] **Step 1: Loosen the category validation in `src/schemas/plan.schema.ts`**
+
+Replace:
+
+```typescript
+const planCategoryEnum = z.enum([
+  "work",
+  "preparation",
+  "travel",
+  "leave",
+  "sick",
+  "training",
+  "other",
+]);
+```
+
+with:
+
+```typescript
+// Category is now a dynamic key (validated against plan_categories in the
+// service). Keep it a non-empty string here.
+const planCategoryEnum = z.string().trim().min(1, "Kategorie je povinná");
+```
+
+Leave every `planCategoryEnum` usage as-is (the `.default("work")` on create still works for a string).
+
+- [ ] **Step 2: Change `buildPlanAuditDescription` to take a resolved label**
+
+In `src/utils/planAuditDescription.ts`, change the `category` field to `categoryLabel` and use it directly. Replace the `PlanAuditDescriptionInput.category` field and the `planCategoryLabel(opts.category)` call:
+
+In the interface:
+
+```typescript
+/** Already-resolved Czech category label (resolved from plan_categories). */
+categoryLabel: string;
+```
+
+(remove the `category: string;` field)
+
+In `buildPlanAuditDescription`, replace:
+
+```typescript
+const parts: string[] = [
+  opts.userName,
+  dateLabel,
+  planCategoryLabel(opts.category),
+];
+```
+
+with:
+
+```typescript
+const parts: string[] = [opts.userName, dateLabel, opts.categoryLabel];
+```
+
+Keep `PLAN_CATEGORY_LABELS_CS` / `planCategoryLabel` exported (still used as a fallback by the service), but they are no longer called inside `buildPlanAuditDescription`.
+
+- [ ] **Step 3: Update the audit-description tests**
+
+In `src/__tests__/planAuditDescription.test.ts`, in every `buildPlanAuditDescription({...})` call replace the `category: "work"` (etc.) field with the resolved label, e.g. `categoryLabel: "Práce"`. Concretely:
+
+- `category: "work"` → `categoryLabel: "Práce"`
+- `category: "leave"` → `categoryLabel: "Dovolená"`
+- `category: "sick"` → `categoryLabel: "Nemoc"`
+
+(The `planCategoryLabel` describe block stays unchanged.)
+
+- [ ] **Step 4: Resolve the label and validate the key in `src/services/plan.service.ts`**
+
+Add a helper near `resolvePlanLabels`:
+
+```typescript
+import { planCategoryLabel as fallbackCategoryLabel } from "../utils/planAuditDescription";
+
+/** Resolve a category key to its Czech label from the DB, falling back to
+ * the built-in map then the raw key. */
+async function resolveCategoryLabel(key: string): Promise<string> {
+  const cat = await prisma.plan_categories.findUnique({
+    where: { key },
+    select: { label: true },
+  });
+  return cat?.label ?? fallbackCategoryLabel(key);
+}
+
+/** Returns an error result if the category key is not an active category. */
+async function assertActiveCategory(
+  key: string,
+): Promise<{ error: string; status: number } | null> {
+  const cat = await prisma.plan_categories.findFirst({
+    where: { key, is_active: true },
+    select: { id: true },
+  });
+  if (!cat) return { error: "Neplatná nebo neaktivní kategorie", status: 400 };
+  return null;
+}
+```
+
+In `createEntry`, after the past-date locks and before `prisma.work_plan_entries.create`, add:
+
+```typescript
+const catErr = await assertActiveCategory(input.category);
+if (catErr) return catErr;
+```
+
+In `updateEntry`, after computing locks and before the `prisma...update`, add (only validate if category provided):
+
+```typescript
+if (input.category) {
+  const catErr = await assertActiveCategory(input.category);
+  if (catErr) return catErr;
+}
+```
+
+Apply the same two patterns to `createOverride` (validate `input.category` before the transaction) and `updateOverride` (validate `input.category` if provided).
+
+Then, in each place that currently builds the description with `category: <row>.category`, resolve the label first and pass `categoryLabel`. For example in `createEntry` replace:
+
+```typescript
+const { userName, projectName } = await resolvePlanLabels(
+  created.user_id,
+  created.project_id,
+);
+const description = buildPlanAuditDescription({
+  userName,
+  category: created.category,
+  projectName,
+  dateFrom: input.date_from,
+  dateTo: input.date_to,
+  force,
+});
+```
+
+with:
+
+```typescript
+const { userName, projectName } = await resolvePlanLabels(
+  created.user_id,
+  created.project_id,
+);
+const categoryLabel = await resolveCategoryLabel(created.category);
+const description = buildPlanAuditDescription({
+  userName,
+  categoryLabel,
+  projectName,
+  dateFrom: input.date_from,
+  dateTo: input.date_to,
+  force,
+});
+```
+
+Apply the same `category: X.category` → `categoryLabel: await resolveCategoryLabel(X.category)` change in `updateEntry`, `deleteEntry`, `createOverride` (both the created row and the `replaced` row), `updateOverride`, and `deleteOverride`.

+
+## Task 6: Frontend categories query + types + helpers
+
+**Files:**
+
+- Modify: `src/admin/lib/queries/plan.ts`
+
+- [ ] **Step 1: Add the type, query, and helpers**
+
+Add the import at the top of `src/admin/lib/queries/plan.ts` (it already imports `queryOptions`, `apiFetch`, `jsonQuery`):
+
+```typescript
+// (queryOptions and jsonQuery are already imported at the top of this file)
+```
+
+Add after the `ResolvedCell` interface:
+
+```typescript
+export interface PlanCategory {
+  id: number;
+  key: string;
+  label: string;
+  color: string;
+  sort_order: number;
+  is_active: boolean;
+}
+
+export const planCategoriesOptions = () =>
+  queryOptions({
+    queryKey: ["plan", "categories"],
+    queryFn: () => jsonQuery<PlanCategory[]>("/api/admin/plan/categories"),
+  });
+
+/** Build a key → category lookup from the categories list. */
+export function categoryMap(
+  categories: PlanCategory[] | undefined,
+): Record<string, PlanCategory> {
+  const map: Record<string, PlanCategory> = {};
+  for (const c of categories ?? []) map[c.key] = c;
+  return map;
+}
+```
+
+Then change `planCategoryLabel` to be map-driven, and DELETE the now-unused internal `PLAN_CATEGORY_LABELS` const. **Keep `PLAN_CATEGORIES` for now** — `PlanCellModal` still imports it; it is removed in Task 8 once the `<select>` no longer uses it (this keeps every commit building). Replace the old `planCategoryLabel` (and remove `PLAN_CATEGORY_LABELS`) with:
+
+```typescript
+/** Czech label for a plan category key, resolved from the loaded categories
+ * map, falling back to the raw key. The `map` arg is optional so callers not
+ * yet threading categories still compile (they show the raw key until wired). */
+export function planCategoryLabel(
+  key: string,
+  map?: Record<string, PlanCategory>,
+): string {
+  return map?.[key]?.label ?? key;
+}
+```
+
+(`cellProjectLabel` stays unchanged. `PLAN_CATEGORIES` is intentionally left in place until Task 8.)
+
+- [ ] **Step 2: Commit**
+
+```bash
+git add src/admin/lib/queries/plan.ts
+git commit -m "feat(plan): add categories query, type, and map helpers (frontend)"
+```
+
+---
+
+## Task 7: Wire categories through the grid + color refactor (CSS)
+
+**Files:**
+
+- Modify: `src/admin/plan.css`
+- Modify: `src/admin/components/PlanGrid.tsx`
+- Modify: `src/admin/components/PlanRangeChips.tsx`
+- Modify: `src/admin/pages/PlanWork.tsx`
+
+- [ ] **Step 1: CSS — make the tape use `--cat-color`**
+
+In `src/admin/plan.css`, change the base tape `.plan-cell::before` `background` line from:
+
+```css
+background: var(--plan-paper-rule);
+```
+
+to:
+
+```css
+background: var(--cat-color, var(--plan-paper-rule));
+```
+
+Then DELETE the seven per-key tape rules (`.plan-cell:has(.plan-chip--work)::before` … `.plan-cell:has(.plan-chip--other)::before`).
+
+- [ ] **Step 2: CSS — make the chip use `--cat-color`**
+
+In the base `.plan-chip` rule, replace these three lines:
+
+```css
+color: var(--plan-ink);
+background: color-mix(in srgb, var(--plan-paper) 60%, var(--plan-paper-soft));
+border: 1px solid var(--plan-paper-rule);
+```
+
+with:
+
+```css
+color: var(--cat-color, var(--plan-ink));
+background: color-mix(
+  in srgb,
+  var(--cat-color, var(--plan-paper-soft)) 10%,
+  var(--plan-paper)
+);
+border: 1px solid
+  color-mix(in srgb, var(--cat-color, var(--plan-paper-rule)) 35%, transparent);
+```
+
+Then DELETE the seven per-key chip rules (`.plan-cell:has(.plan-chip--work) .plan-chip--work` … `.plan-cell:has(.plan-chip--other) .plan-chip--other`).
+
+Update the dark override from:
+
+```css
+[data-theme="dark"] .plan-chip {
+  background: color-mix(in srgb, var(--plan-cell-bg) 90%, var(--plan-paper));
+}
+```
+
+to:
+
+```css
+[data-theme="dark"] .plan-chip {
+  background: color-mix(
+    in srgb,
+    var(--cat-color, var(--plan-cell-bg)) 16%,
+    var(--plan-paper)
+  );
+}
+```
+
+- [ ] **Step 2b: CSS — keep the decorative grain static**
+
+The paper-grain gradient (search for `--plan-tape-work` / `--plan-tape-training` around the `.plan-grid-wrap::before` area) is cosmetic; leave it and the `--plan-tape-*` variable definitions in place. No change.
+
+- [ ] **Step 3: PlanGrid — accept categories, set `--cat-color`, pass label**
+
+In `src/admin/components/PlanGrid.tsx`:
+
+Change the import:
+
+```typescript
+import {
+  GridData,
+  ResolvedCell,
+  planCategoryLabel,
+  categoryMap,
+  PlanCategory,
+} from "../lib/queries/plan";
+```
+
+Add `categories` to `Props`:
+
+```typescript
+  categories: PlanCategory[];
+```
+
+Destructure it in the component signature alongside `canEdit`, and build the map once (inside the component body, before the return / inside the existing `useMemo` area):
+
+```typescript
+const catMap = useMemo(() => categoryMap(categories), [categories]);
+```
+
+On the cell `<button>`, add an inline style with the color when the cell has a category. Change the `<button ...>` opening tag to include:
+
+```tsx
+                        style={
+                          cell
+                            ? ({ "--cat-color": catMap[cell.category]?.color } as React.CSSProperties)
+                            : undefined
+                        }
+```
+
+In the aria-label, change `planCategoryLabel(cell.category)` to `planCategoryLabel(cell.category, catMap)`.
+Pass the label to the chips — change the `<PlanRangeChips ... />` usage to add:
+
+```tsx
+                          categoryLabel={cell ? planCategoryLabel(cell.category, catMap) : ""}
+```
+
+(If `React` is not imported, add `import { useMemo } from "react";` already exists; for the `React.CSSProperties` cast add `import type { CSSProperties } from "react";` and use `as CSSProperties`.)
+
+- [ ] **Step 4: PlanRangeChips — render label from prop**
+
+In `src/admin/components/PlanRangeChips.tsx`:
+
+- Remove `planCategoryLabel` from the import (keep `cellProjectLabel`, `ResolvedCell`).
+- Add `categoryLabel: string;` to `Props`.
+- Destructure `categoryLabel` and render it. Replace:
+
+```tsx
+<span className={`plan-chip plan-chip--${cell.category}`}>
+  {planCategoryLabel(cell.category)}
+</span>
+```
+
+with:
+
+```tsx
+<span className="plan-chip">{categoryLabel}</span>
+```
+
+(The per-key class is no longer needed; color comes from the inherited `--cat-color`.)
+
+- [ ] **Step 5: PlanWork — load categories and pass to the grid**
+
+In `src/admin/pages/PlanWork.tsx`:
+Add the import:
+
+```typescript
+import { planCategoriesOptions, PlanCategory } from "../lib/queries/plan";
+```
+
+After the projects query (`const projects: Project[] = ...`), add:
+
+```typescript
+const { data: categoriesData } = useQuery(planCategoriesOptions());
+const categories: PlanCategory[] = categoriesData ?? [];
+```
+
+Pass to the grid — in `<PlanGrid ... />` add:
+
+```tsx
+categories = { categories };
+```
+
+- [ ] **Step 6: Build the client**
+
+Run: `npm run build:client`
+Expected: BUILD-EXIT 0.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add src/admin/plan.css src/admin/components/PlanGrid.tsx src/admin/components/PlanRangeChips.tsx src/admin/pages/PlanWork.tsx
+git commit -m "feat(plan): render category colors from DB via --cat-color"
+```
+
+---
+
+## Task 8: Plan create/edit `<select>` uses active categories
+
+**Files:**
+
+- Modify: `src/admin/components/PlanCellModal.tsx`
+- Modify: `src/admin/pages/PlanWork.tsx`
+
+- [ ] **Step 1: Pass categories into the modal**
+
+In `src/admin/components/PlanCellModal.tsx`:
+Change the import to drop the removed `PLAN_CATEGORIES` and use the categories from props:
+
+```typescript
+import {
+  ResolvedCell,
+  planCategoryLabel,
+  cellProjectLabel,
+  PlanCategory,
+} from "../lib/queries/plan";
+```
+
+Add `categories: PlanCategory[];` to the `Props` interface (next to `projects`).
+
+In `EditForm`, derive active categories and a label map from props. Near the top of `EditForm` (after `const isOverride = ...`):
+
+```typescript
+const activeCategories = props.categories.filter((c) => c.is_active);
+```
+
+Replace the category `<select>` options (`{PLAN_CATEGORIES.map((c) => (...))}`) with:
+
+```tsx
+{
+  activeCategories.map((c) => (
+    <option key={c.key} value={c.key}>
+      {c.label}
+    </option>
+  ));
+}
+```
+
+In `ViewModal`, build a map and resolve the label. Replace:
+
+```tsx
+        <strong>Kategorie:</strong> {planCategoryLabel(c.category)}
+```
+
+with:
+
+```tsx
+        <strong>Kategorie:</strong>{" "}
+        {planCategoryLabel(
+          c.category,
+          Object.fromEntries(props.categories.map((x) => [x.key, x])),
+        )}
+```
+
+Finally, now that `PlanCellModal` no longer references `PLAN_CATEGORIES`,
+**remove the exported `PLAN_CATEGORIES` const** from
+`src/admin/lib/queries/plan.ts` (it was kept alive only for this select). Grep
+to confirm no other importer remains: `npx rg "PLAN_CATEGORIES" src` should
+return nothing.
+
+- [ ] **Step 2: Pass categories from PlanWork to the modal**
+
+In `src/admin/pages/PlanWork.tsx`, add the JSX prop `categories={categories}` to
+the `<PlanCellModal ... />` element.
+
+- [ ] **Step 3: Build the client**
+
+Run: `npm run build:client`
+Expected: BUILD-EXIT 0.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/admin/components/PlanCellModal.tsx src/admin/pages/PlanWork.tsx
+git commit -m "feat(plan): drive category select and view label from DB categories"

+
+- As an `attendance.manage` user: "Správa kategorií" button is visible above the calendar; a view-only user does NOT see it.
+- Add a category (label + color) → it appears in the create/edit plan `<select>` and its color shows on a new entry's chip + tape.
+- Recolor an existing category → all entries with that category recolor after the grid refetch.
+- Rename a category → the chip/label/select update.
+- "Skrýt" (deactivate) a category in use → it disappears from the `<select>` but existing entries still show its label/color; cannot hide the last active one (Czech error).
+- Audit log shows `Plán prací – kategorie` rows for category changes.
+
+- [ ] **Step 5: Final commit (if any stray changes)**
+
+```bash
+git add -A
+git commit -m "chore(plan): finalize category management"
+```
+
+---
+
+## Self-review notes (addressed)
+
+- **Spec coverage:** table + enum→varchar + seed (Task 1); CRUD API + permissions + audit (Task 4); dynamic validation + audit label (Task 5); categories query/type (Task 6); color refactor (Task 7); dynamic select + view label (Task 8); management modal + button (Task 9); audit entity labels (Task 10); tests (Task 3/5/11).
+- **Deactivate semantics:** GET returns all categories (display keeps working for retired ones); `<select>` filters to active; last-active guard in `updatePlanCategory`.
+- **Type consistency:** service returns `{ data } | { error, status }`; `planCategoryLabel(key, map)` signature used consistently in PlanGrid/PlanCellModal; `categories: PlanCategory[]` threaded PlanWork → PlanGrid/PlanRangeChips(label)/PlanCellModal.
+- **`buildPlanAuditDescription`** now takes `categoryLabel` everywhere it is called (service Task 5, tests Task 5 step 3).

+# Warehouse (Sklad) Module Design
+
+**Date:** 2026-05-29
+**Status:** Approved
+**Module:** Warehouse/Inventory management for boha-app-ts
+
+---
+
+## Overview
+
+Full warehouse management module under the Administration section. Tracks material receiving, issuing, reservations, inventory, and project assignment. Uses true FIFO with batch-level tracking, document-driven architecture (header + lines), and integrates with existing projects, number sequences, and NAS file storage.
+
+---
+
+## Requirements
+
+### Movements
+
+- **Receipt (Prijem):** Material enters warehouse. Multi-item document with delivery note attachment.
+- **Issue (Vydej):** Material leaves warehouse, mandatory project assignment. Multi-item document.
+- **Reservation:** Virtual hold on stock before issue. Reduces available qty but not physical stock. Issue consumes reservation.
+- **Inventory (Inventura):** Corrective movements based on physical count vs system count.
+- **Storno:** Cancel a confirmed receipt or issue. Creates opposite corrective movements, preserves audit trail.
+
+### Catalog
+
+- Each material has: catalog number, name, description, category, unit, min quantity.
+- Categories are user-defined (CRUD).
+- Units are fixed list: ks, m, kg, bal, sada, m2, m3, l.
+- Items can be soft-deactivated (is_active=false).
+
+### Pricing
+
+- Purchase price per unit, recorded bez DPH.
+- True FIFO: each receipt line creates a batch. Issues consume oldest batches first.
+- Batch-level tracking with remaining quantity.
+
+### Delivery Notes
+
+- File attachment (PDF/image) uploaded to NAS.
+- Delivery note number and date stored as metadata on receipt header.
+
+### Suppliers
+
+- Separate `sklad_suppliers` table (ICO, DIC, contact info).
+- Not shared with customers table.
+
+### Locations
+
+- Warehouse has named locations/shelves (code + name, e.g. "A1 - Regal A, police 1").
+- Junction table tracks qty per item per location.
+
+### Projects
+
+- Every issue is mandatory FK to `projects` table.
+- No free/issues without project assignment.
+
+### Min Stock Alerts
+
+- Each item has optional `min_quantity`.
+- Dashboard highlights items below minimum.
+- No email notification (UI alert only).
+
+### Immutability
+
+- All movements are immutable once confirmed.
+- Corrections via storno (cancel receipt/issue) which creates opposite movements.
+- Draft movements can be edited freely.
+
+### Numbering
+
+- Auto-numbering via `number_sequences` on confirm.
+- Types: `warehouse_receipt` (e.g. PRI-2026-001), `warehouse_issue` (e.g. VYD-2026-001).
+
+### Issue Documents
+
+- No PDF generation for issues. Record only in system.
+
+### Reports
+
+- Stock status: all items with qty, min_qty, value, below-min flag.
+- Project consumption: material consumed per project (filter by project, date range).
+- Movement log: all receipts + issues with filters.
+- Below minimum: items under min_quantity.
+
+---
+
+## Architecture: Document-Driven
+
+Each movement type is a document (header + lines), matching the existing invoice/offer pattern.
+
+### Document Flow
+
+```
+DRAFT → CONFIRMED (affects stock)
+DRAFT → CANCELLED (no stock effect)
+CONFIRMED → CANCELLED (storno: reverses stock changes)
+```
+
+Only CONFIRMED documents affect `sklad_batches`, `sklad_item_locations`, and reservations.
+

+
+## Business Logic
+
+### Receipt Confirm (single Prisma transaction)
+
+1. Validate status is DRAFT
+2. Generate `receipt_number` via `number_sequences` (type: `warehouse_receipt`)
+3. For each receipt line:
+   - Create `sklad_batches` row (quantity = original_qty = line qty, unit_price from line, received_at = now)
+   - Upsert `sklad_item_locations` (add qty to specified location)
+4. Update receipt status to CONFIRMED
+5. Log audit
+
+### Receipt Cancel
+
+**If DRAFT:** Set status to CANCELLED. No stock changes.
+
+**If CONFIRMED (storno):**
+
+1. Validate no issue lines have consumed batches from this receipt
+2. For each receipt line / batch:
+   - If batch is fully consumed (is_consumed=true), reject cancellation
+   - Decrement `sklad_item_locations` by batch remaining quantity
+   - Delete the batch row
+3. Set receipt status to CANCELLED
+4. Log audit
+
+### Issue Confirm (single Prisma transaction)
+
+1. Validate status is DRAFT
+2. For each issue line, validate: batch has enough remaining quantity
+3. Generate `issue_number` via `number_sequences` (type: `warehouse_issue`)
+4. For each issue line:
+   - Decrement `sklad_batches.quantity`, set `is_consumed=true` if 0
+   - Decrement `sklad_item_locations.quantity`
+   - If `reservation_id` set, decrement `sklad_reservations.remaining_qty`
+5. Check reservations: if remaining_qty = 0, set status to FULFILLED
+6. Update issue status to CONFIRMED
+7. Log audit
+
+### Issue Cancel
+
+**If DRAFT:** Set status to CANCELLED. No stock changes.
+
+**If CONFIRMED (storno):**
+
+1. For each issue line:
+   - Increment `sklad_batches.quantity`, set `is_consumed=false` if was true
+   - Increment `sklad_item_locations.quantity`
+   - If `reservation_id` set, increment `sklad_reservations.remaining_qty`, set status back to ACTIVE if was FULFILLED
+2. Set issue status to CANCELLED
+3. Log audit
+
+### Auto-FIFO on Issue Creation
+
+When creating an issue line, if user doesn't pick a specific batch:
+
+- Service selects oldest unconsumed batches for the item (via `sklad_batches_fifo` index)
+- May span multiple batches if quantity exceeds one batch's remaining qty
+- Frontend shows available batches for manual override
+
+### Reservation Creation
+
+1. Validate item exists and is_active
+2. Calculate available_qty = total stock qty - sum of active reservation quantities for this item
+3. Validate available_qty >= requested quantity
+4. Create reservation with quantity = remaining_qty
+5. Does NOT modify `sklad_batches` or `sklad_item_locations`
+
+### Inventory Confirm (single Prisma transaction)
+
+1. Validate status is DRAFT
+2. For each inventory line where difference != 0:
+   - If difference > 0 (more stock than system): create a corrective receipt (type: inventory, auto-confirmed)
+   - If difference < 0 (less stock than system): create a corrective issue (type: inventory, auto-confirmed)
+3. Generate `session_number` via `number_sequences` (type: `warehouse_inventory`)
+4. Set status to CONFIRMED
+5. Log audit

+
+## Constraints & Edge Cases
+
+1. **Batch consumption on cancel:** If any batch from a receipt has been partially or fully consumed by an issue, the receipt cannot be cancelled. User must first cancel the consuming issues.
+
+2. **Reservation availability:** Available qty = sum of active batch quantities - sum of active reservation quantities. Reservation creation validates available_qty >= requested.
+
+3. **Location qty consistency:** `sklad_item_locations` is a denormalized cache for quick lookups. It must always stay in sync with `sklad_batches`. The confirm/cancel transactions maintain this.
+
+4. **FIFO spanning batches:** When auto-FIFO selects batches for an issue line and the quantity spans multiple batches, the service creates **multiple issue lines** (one per batch consumed), all under the same issue document. The user's original requested quantity is preserved across the split lines. This works because each `sklad_issue_lines` row has exactly one `batch_id`.
+
+5. **Inventory corrective movements:** On confirm, each line with a difference creates an auto-confirmed receipt or issue. The `notes` field of these corrective documents references the inventory session ID and line, so they can be traced back. These corrective documents are fully audited like manual receipts/issues.
+
+6. **Unit consistency:** Once an item is created with a unit, it cannot be changed if any movements exist. This prevents unit mismatches in stock calculations.

+# Manual project & order creation — design
+
+Date: 2026-06-06
+Status: approved (pending spec review)
+Author: Claude + BOHA
+
+## Problem
+
+Today both entities are only ever _derived_ from a parent:
+
+- A **project** is created solely as a side-effect of `createOrderFromQuotation`
+  (`orders.service.ts`). There is **no** `POST /projects`, no `createProject`
+  service, no `CreateProjectSchema`. A manual-create feature existed but was
+  **removed in commit `82919d3`** (2026-04-28) — the note: _"Projects can only
+  be created through orders (shared numbering sequence)."_ The old code pulled
+  `project_number` from the shared order/project pool, which consumed an order
+  number and left **gaps in order numbering**. That is the bug we must not repeat.
+- An **order** is normally created from an offer. A manual `createOrder`
+  (`orders.service.ts`, offer-less) **already exists** and the route already
+  dispatches to it, but there is **no UI**, and it does not create a project.
+
+We want: (1) manually create projects on `/projects`, (2) manually create
+orders without an offer on `/orders`.
+
+## Decisions (locked with the user)
+
+1. **Project numbering: shared pool, _with_ proper tracking.** Standalone
+   projects take the next **shared** number via `generateSharedNumber()` — the
+   same pool as orders — but we add the tracking/transparency that was missing
+   before (see "Tracking" below). Auto-assigned; no manual number entry.
+2. **Manual order → project: optional checkbox, default ON.** The order form
+   has a pre-checked "Vytvořit propojený projekt"; when set, the order and its
+   project share the order number (identical to the from-offer flow → no gap).
+3. **Order form scope: header only.** Customer, customer order number,
+   currency/VAT, scope title/description, notes. No line-item editor.
+4. **Customer: optional** on both forms (matches the existing nullable schema).
+5. **Match existing house design** — `FormModal` + `FormField`, the
+   `Vehicles.tsx` create/edit-modal pattern, the `OffersCustomers.tsx`
+   header-button + customer-selector pattern, existing list/badge styling.
+
+## Why the shared pool is safe here (the tracking)
+
+The shared sequence is effectively a single "zakázkové číslo" pool. An order and
+its project share one number; a standalone project simply takes the next number
+in that pool and has no order. The mechanics that make this coherent:
+
+- **Collision-safe:** `isSharedNumberTaken()` already checks **both**
+  `orders.order_number` and `projects.project_number`, so the same number can
+  never be issued twice across the pool (`numbering.service.ts:161-167`).
+- **Atomic:** `createProject` wraps `generateSharedNumber(tx)` in
+  `prisma.$transaction` — the existing `SELECT … FOR UPDATE` lock
+  (`getNextSequence`) serialises concurrent consumers.
+- **Release on delete:** `deleteProject` already calls `releaseSharedNumber`,
+  which decrements the sequence only if the deleted number is the current
+  highest — so deleting a standalone project doesn't leave a permanent tail-gap
+  (`numbering.service.ts:116-158, 319-328`).
+- **Audit trail:** `logAudit` on create/delete records the number in
+  `newValues`/`oldValues`, so every consumed pool number has a "who/when/what"
+  trail showing it went to a project (not a lost order).
+- **UI transparency:** the Projects list shows a badge — **"z objednávky"**
+  (order-linked, `order_id != null`) vs **"samostatný"** (standalone) — so a
+  pool number with no order reads as intentional. The create form previews the
+  number it is about to assign (`previewSharedNumber()`).
+
+## Part A — Manual projects
+
+### Backend
+
+- **`src/schemas/projects.schema.ts`** — add `CreateProjectSchema`
+  (`z.strictObject`, shared coercers from `schemas/common.ts`, Czech messages):
+  - `name` — required, `z.string().min(1)`.
+  - `customer_id` — optional number (coerced, NaN-guarded).
+  - `responsible_user_id` — optional number.
+  - `status` — optional, default `"aktivni"`.
+  - `start_date`, `end_date` — optional date strings.
+  - `notes` — optional string.
+  - **No** `project_number` field (auto-assigned from the pool).
+- **`src/services/projects.service.ts`** — add `createProject(data)`:
+  - `prisma.$transaction(async (tx) => …)`: `project_number = await
+generateSharedNumber(tx)`; `tx.projects.create({ … order_id: null,
+quotation_id: null, status: data.status ?? "aktivni", … })`.
+  - Validate `customer_id` / `responsible_user_id` exist (when provided) →
+    return `{ error, status: 400 }` (Czech) if not.
+  - After commit: `nasFileManager.createProjectFolder(number, name)` when
+    `isConfigured()` — non-fatal, logged on failure (mirrors the old code).
+  - Return `{ data: project }` (or `{ error, status }`).
+- **`src/routes/admin/projects.ts`**:
+  - `POST /` guarded by `requirePermission("projects.create")` →
+    `parseBody(CreateProjectSchema, …)` → `createProject` → `logAudit`
+    (`action: "create"`, `entityType: "project"`, `newValues`) →
+    `success(reply, project, 201, "Projekt vytvořen")`.
+  - `GET /next-number` guarded by `projects.create` → `previewSharedNumber()` →
+    `success(reply, { number })`. (Preview only; does not consume.)
+
+### Frontend (`src/admin/pages/Projects.tsx` + new modal)
+
+- Header **"Přidat projekt"** button, gated on `hasPermission("projects.create")`,
+  matching the `OffersCustomers.tsx` "Přidat zákazníka" header-button pattern.
+- A project create `FormModal` (house pattern from `Vehicles.tsx`): `FormField`
+  rows for name (required), customer (select from customers list), responsible
+  user (select from `userListOptions`), status, start/end dates, notes, plus a
+  read-only "Číslo projektu: `<preview>` (přiděleno automaticky)" line fetched
+  from `GET /projects/next-number` when the modal opens.
+- `useApiMutation` POST `/api/admin/projects`; on success invalidate
+  **`["projects"]`** (broad domain key, per the invalidation convention) and
+  close modal; surface server errors via `useAlert`.
+- List: add the **"z objednávky" / "samostatný"** badge (derive from
+  `order_id`). Update the empty-state text (currently "Projekt se vytvoří
+  automaticky při vytvoření objednávky") to mention manual creation.
+
+## Part B — Manual orders (header only, optional project)
+
+### Backend
+
+- **`src/schemas/orders.schema.ts`** — add `create_project` to
+  `CreateOrderSchema`: boolean via the existing `preprocess(v => v === true || v
+=== 1 || v === "1")` idiom, `.optional().default(true)`. (Only the manual path
+  uses this schema; the from-quotation path uses `CreateOrderFromQuotationSchema`.)
+- **`src/services/orders.service.ts` `createOrder`** — inside the existing
+  transaction, after the order is created, when `body.create_project` is true and
+  there is no quotation link: `tx.projects.create({ project_number: orderNumber,
+order_id: order.id, customer_id: order.customer_id, name: scope_title ??
+customer_order_number ?? orderNumber, status: "aktivni" })` — mirrors
+  `createOrderFromQuotation`'s project block, so order + project share the number.
+  Return the project id so the route can audit it.
+- **`src/routes/admin/orders.ts`** — the manual `POST /` branch already exists
+  (`orders.create`); add a second `logAudit` for the created project when present.
+
+### Frontend (`src/admin/pages/Orders.tsx` + new modal)
+
+- Header **"Vytvořit objednávku"** button, gated on `orders.create`.
+- Header-only `FormModal`: customer (select), customer order number, currency,
+  VAT rate + apply-VAT, language, scope title, scope description, notes, and a
+  pre-checked **"Vytvořit propojený projekt"** checkbox. Read-only next
+  order-number preview via the existing `GET /api/admin/orders/next-number`.
+- POST `/api/admin/orders` (no `quotationId`); on success invalidate
+  **`["orders"]`** and **`["projects"]`**; errors via `useAlert`.
+
+## Part C — Permissions
+
+`projects.create` was removed from the permission set and must come back the
+**migration** way (per CLAUDE.md — never seed-only for prod data):
+
+- New migration `prisma/migrations/<ts>_add_projects_create_permission/` that
+  `INSERT`s the `projects.create` permission row and grants it to the **admin**
+  role (mirror `20260603230000_add_warehouse_permissions/migration.sql`). Use
+  `INSERT … ON DUPLICATE KEY UPDATE` / `INSERT IGNORE` style so re-runs are safe.
+- Add `projects.create` to the `PERMISSIONS` array in `prisma/seed.ts` (dev).
+- `orders.create` already exists — no change.
+
+## Part D — Tests (`src/__tests__/`)
+
+Real-DB Vitest (no Prisma mocks), following `numbering.test.ts` style:
+
+- `createProject` assigns the next shared number, increments the `shared`
+  sequence by exactly 1, sets `order_id = null`, writes an audit row.
+- `createOrder` with `create_project: true` creates an order **and** a project
+  sharing one `order_number`/`project_number`.
+- Interleaved coherence: order → standalone project → order produces three
+  consecutive shared numbers with no duplicates (the tracking guarantee).
+- `createOrder` with `create_project: false` creates only the order.
+
+## Error handling
+
+- Service returns `{ error, status }` (Czech) for bad customer/user FK and

+- NAS folder creation is non-fatal and logged (never blocks creation).

+
+- Editing order line-items after creation.
+- Attaching a standalone project to an order later (conflicts with current
+  `order_id` immutability + the `has_order` delete guard).

+# Plan Categories Management — Design Spec
+
+Date: 2026-06-06
+Status: Approved (approach A)
+Area: Work Plan (`/plan-work`)
+
+## Goal
+
+Let managers (`attendance.manage`) **create, rename, recolor, and retire** the
+categories used by the work plan, via a "Správa kategorií" button above the
+calendar that opens a form modal with a per-category color picker. Categories
+become data, not a hardcoded enum.
+
+## Current state (what's hardcoded today)
+
+- DB: `plan_category` **enum** (`work, preparation, travel, leave, sick,
+training, other`) used by `work_plan_entries.category` and
+  `work_plan_overrides.category` (both `NOT NULL`).
+- Validation: `planCategoryEnum` in `src/schemas/plan.schema.ts`.
+- Frontend labels: `PLAN_CATEGORIES` / `planCategoryLabel` in
+  `src/admin/lib/queries/plan.ts`.
+- Colors: per-category CSS variables `--plan-tape-<key>` in `src/admin/plan.css`,
+  applied via `.plan-cell:has(.plan-chip--<key>)::before` (left "tape" bar) and
+  `.plan-chip--<key>` (chip text/border/background via `color-mix`). 14 rules.
+- Server audit: `PLAN_CATEGORY_LABELS_CS` in `src/utils/planAuditDescription.ts`.
+- A decorative paper-grain gradient (`plan.css` ~lines 102–107) tints the page
+  background with `--plan-tape-work` / `--plan-tape-training` at 5%. This is
+  cosmetic and **not** category-semantic.
+
+## Approach (A)
+
+Introduce a `plan_categories` table. Keep the entry/override `category` column
+as a **string key** (slug) referencing `plan_categories.key`. Change the column
+type from the enum to `VARCHAR(50)`; existing values are preserved verbatim.
+"Remove" means **deactivate** (`is_active = false`), never hard-delete, so
+historical entries keep resolving their label and color.
+
+Rejected: a real FK `category_id` (needs per-row backfill + read/write churn for
+no user-visible benefit); keeping the enum (can't add categories).
+
+## Data model
+
+New table `plan_categories`:
+
+| column     | type         | notes                                        |
+| ---------- | ------------ | -------------------------------------------- |
+| id         | INT PK AI    |                                              |
+| key        | VARCHAR(50)  | UNIQUE, slug, immutable after create         |
+| label      | VARCHAR(100) | Czech display name, editable                 |
+| color      | VARCHAR(7)   | `#RRGGBB`                                    |
+| sort_order | INT          | display order; new categories append (max+1) |
+| is_active  | BOOLEAN      | default true; false = retired                |
+| created_at | DATETIME     | default now                                  |
+| updated_at | DATETIME     | auto                                         |
+
+Column change: `work_plan_entries.category` and `work_plan_overrides.category`
+`plan_category` → `VARCHAR(50) NOT NULL`. Drop the `plan_category` enum from the
+Prisma schema once no column uses it.
+
+## Migration (one tracked Prisma migration)
+
+`npx prisma migrate dev --name plan_categories` (requires dev server stopped —
+ask the user first per CLAUDE.md). The generated `migration.sql` will:
+
+1. `CREATE TABLE plan_categories (...)`.
+2. `ALTER` the two `category` columns enum → `VARCHAR(50)`.
+3. `INSERT` the 7 seed rows (so production gets them — not seed-only, per the
+   migration policy). Seed values (key, label, color, sort_order):
+
+   | key         | label          | color   | sort |
+   | ----------- | -------------- | ------- | ---- |
+   | work        | Práce          | #2563eb | 1    |
+   | preparation | Příprava       | #0d9488 | 2    |
+   | travel      | Cesta / Montáž | #ca8a04 | 3    |
+   | leave       | Dovolená       | #16a34a | 4    |
+   | sick        | Nemoc          | #dc2626 | 5    |
+   | training    | Školení        | #7c3aed | 6    |
+   | other       | Jiné           | #6b7280 | 7    |
+
+After: `npx prisma generate`, commit schema + migration folder.
+
+## API — `/api/admin/plan/categories`
+
+All under the existing plan route file group.
+
+- `GET /` — returns **all** categories (active + inactive), ordered by
+  `sort_order, id`. Readable by `attendance.record` OR `attendance.manage`
+  (every grid viewer needs labels/colors, including for retired categories on
+  historical entries).
+- `POST /` — create. `attendance.manage`. Body: `{ label, color }`. `key` is
+  auto-slugged from `label` (ASCII, lowercased, deduped); `sort_order = max+1`.
+- `PATCH /:id` — update `label` / `color` / `is_active`. `attendance.manage`.
+  `key` is immutable.
+- `DELETE /:id` — deactivate (`is_active = false`). `attendance.manage`.
+
+Service layer: `src/services/planCategory.service.ts` (plain async functions,
+`{ data }` / `{ error, status }` envelope). Audit-logged via `logAudit` with a
+new entity type `plan_category` (add to `EntityType` and the AuditLog +
+dashboard `ENTITY_TYPE_LABELS` maps, e.g. "Plán prací – kategorie").
+
+Validation (`src/schemas/plan.schema.ts` or a new `planCategory.schema.ts`):
+
+- `label`: required, 1–100 chars, trimmed.
+- `color`: regex `^#[0-9a-fA-F]{6}$`.
+- `is_active`: boolean (PATCH only).
+- Entry/override create/update: `category` becomes `z.string().min(1)`; the
+  **service** validates the key exists and `is_active` (reject unknown/inactive
+  with a Czech 400).
+
+## Validation rules / edge cases
+
+- **Slug collision:** if the slug derived from a new label already exists,
+  append `-2`, `-3`, … Keys are never shown to users.
+- **At least one active category:** deactivating the last active category is
+  rejected (Czech 400) so the create form is never empty.
+- **Deactivate in use:** allowed. Existing entries keep their key; the category
+  still renders (GET returns inactive ones) but is hidden from the create
+  `<select>`.
+- **Rename/recolor:** applies to all entries with that key (reference is by
+  key) — this is the desired "recolor everywhere" behavior.
+- **No hard delete** in this iteration (deactivate only). Possible later
+  enhancement: allow hard-delete when zero entries reference the key.
+
+## Frontend
+
+- **Button** "Správa kategorií" in `PlanWork.tsx` header, rendered only when
+  `hasPermission("attendance.manage")`.
+- **Modal** (`PlanCategoriesModal.tsx`, uses `FormModal`): a row per category =
+  `label` text input + native `<input type="color">` swatch + active toggle (or
+  a "retire/restore" control), plus an "add category" row (label + color +
+  add). Mutations invalidate `["plan", "categories"]` **and** `["plan"]` (so the
+  grid recolors) and `["dashboard"]`/`["audit-log"]` (audit feed).
+- **Category query** `["plan","categories"]` loaded in `PlanWork`, passed to the
+  grid and cell modal. The create/edit plan `<select>` lists **active**
+  categories from this query (replacing hardcoded `PLAN_CATEGORIES`); display
+  uses the **full** map (so retired categories still render).
+- `planCategoryLabel` becomes a lookup into the categories map (with raw-key
+  fallback). `PLAN_CATEGORIES` constant is removed.
+
+## Color rendering (the notable refactor)
+
+Replace the 14 hardcoded per-key rules with a generic, custom-property-driven
+treatment:
+
+- `PlanGrid` sets `style={{ "--cat-color": color }}` on the `.plan-cell`
+  `<button>` when the cell has a category (`color` from the categories map). The
+  custom property cascades to the chip and is available to the cell's `::before`
+  tape.
+- `plan.css`:
+  - `.plan-cell::before` tape uses
+    `background: var(--cat-color, var(--plan-tape-other))` — the graphite
+    `#6b7280` is the defensive neutral fallback when a cell has no category
+    color (replaces the seven `:has(.plan-chip--<key>)::before` rules).
+  - `.plan-chip` (generic) uses `color: var(--cat-color)`,
+    `border-color: color-mix(in srgb, var(--cat-color) 35%, transparent)`,
+    `background: color-mix(in srgb, var(--cat-color) 10%, var(--plan-paper))`
+    (replaces the seven `.plan-chip--<key>` rules).
+- Visual output is identical for the existing 7; new categories work with no CSS
+  changes.
+- The decorative paper-grain gradient stays static (keep two literal colors or
+  the two `--plan-tape-*` vars it needs); it is not category-semantic.
+
+## Audit description
+
+`src/services/plan.service.ts` builds the audit description with the category
+label. Since labels now live in the DB, resolve the label from `plan_categories`
+by key (alongside the existing `resolvePlanLabels` lookups) and pass the plain
+label into `buildPlanAuditDescription`. `src/utils/planAuditDescription.ts`'s
+`buildPlanAuditDescription` stays pure (receives the resolved label);
+`PLAN_CATEGORY_LABELS_CS`/`planCategoryLabel` there are removed or reduced to a
+fallback.
+
+## Testing
+
+Vitest (real DB, per project convention):
+
+- `planCategory.service` CRUD: create (slug generation, sort_order), update
+  (label/color/active), deactivate, and the "last active category" guard.
+- Color/label validation rejects bad hex and empty label.
+- Entry create accepts an active key and rejects an unknown/inactive key.
+
+## Out of scope (YAGNI)
+
+- Per-category icons.
+- Drag-to-reorder (order by `sort_order, id`; new categories append).
+- Hard delete of unused categories (deactivate only).
+
+## Assumptions to confirm
+
+- "Remove" = deactivate (history preserved). ✅ implied by approach A.
+- Native browser color picker (`<input type="color">`), not a custom palette.

+ * - Handlers call the SAME service functions the routes use (or replicate a
