 ## Architecture & Key Patterns
 
-### Request Flow
+### Request flow
 
 ```
 Request → CORS → Cookie → Rate-limit → Security headers
-       → requirePermission() or requireAuth()
-       → Zod schema validation (parseBody helper)
-       → Route handler
-       → Service function
-       → Prisma
-       → success(reply, data) or error(reply, message, status)
+       → requirePermission() / requireAnyPermission()
+       → parseBody(Schema) / parseId(param)
+       → Route handler → Service function → Prisma
+       → success(reply, data) | error(reply, czechMessage, status)
 ```
 
-### Response Format
+### Response format
 
-All responses use this shape:
+`{ success: true, data, message?, pagination? }` on success,
+`{ success: false, error }` on failure. Always the `success()`/`error()`/
+paginated helpers — never raw `reply.send()`.
 
-```typescript
-// Success
-{ success: true, data: T, message?: string, pagination?: {...} }
+### Services
 
-// Error
-{ success: false, error: string }
-```
-
-Use the `success()` and `error()` helpers in routes — never write raw `reply.send()`.
-
-### Service Pattern
-
-Services are plain exported async functions, no classes:
-
-```typescript
-// src/services/foo.service.ts
-export async function getFoo(id: number) {
-  const result = await prisma.foo.findUnique({ where: { id } });
-  if (!result) return { error: "Not found", status: 404 };
-  return { data: result };
-}
-
-// src/routes/admin/foo.ts
-const result = await getFoo(id);
-if ("error" in result) return error(reply, result.error, result.status ?? 400);
-return success(reply, result.data);
-```
-
-### Error Handling
-
-- Routes map service errors to HTTP responses using the pattern above.
-- Global error handler in `server.ts` catches all unhandled exceptions; returns 500 with Czech message.
-- **Never silently swallow errors.** Even if a failure is non-fatal, log it: `app.log.error(e, 'context')`.
-- Error messages are in Czech (this is intentional — user-facing messages, Czech company).
+Plain exported async functions; services own Prisma, routes stay thin.
+Preferred error shape: return **token literals** (`"not_found"`,
+`"invalid_transition"`, `"supplier_not_found"`, …) and let the ROUTE map
+tokens to Czech messages + HTTP codes (the offers/issued-orders modules are
+the reference). Legacy services return `{ error: czech, status }` — fine to
+keep until touched; never the discriminated-union style. Respect soft-delete
+(`is_deleted: false`) in reads where the model has it.
 
 ### Permissions
 
-```typescript
-// Route-level guard
-fastify.addHook("preHandler", requirePermission("invoices.view"));
-// or multiple
-fastify.addHook(
-  "preHandler",
-  requirePermission("invoices.view", "invoices.edit"),
-);
+`requirePermission("entity.action")` / `requireAnyPermission(…)`. The admin
+role bypasses checks (shortcut: `authData.roleName === "admin"` —
+⚠️ `AuthData` has **`roleName`**, not `role`; don't type `authData` as `any`).
+GET list/detail endpoints need a permission guard too, NOT bare `requireAuth`
+(bare-auth reads leak data to any logged-in user). Frontend rule: a _view_
+permission opens pages read-only; an _edit_ permission unlocks fields and
+save buttons.
 
-// Admin role bypasses all permission checks
-// Permissions follow the pattern: "entity.action" (e.g., "users.create", "invoices.delete")
-```
+### Audit
 
-### Audit Logging
-
-Call `logAudit()` from `src/utils/audit.ts` whenever data is created/updated/deleted.
-Pass `oldData` and `newData` so the diff is stored. Audit failures are non-fatal.
-
-### Validation
-
-Use Zod schemas from `src/schemas/`. All route bodies must be validated:
-
-```typescript
-const body = parseBody(FooSchema, request.body);
-if ("error" in body) return error(reply, body.error, 400);
-```
+`logAudit()` on every create/update/delete (and security-relevant actions)
+with `oldValues`/`newValues`. Use a `"(koncept)"`-style fallback in
+descriptions for unnumbered drafts. Audit failures are non-fatal.

-## Date & Timezone Handling (Critical Gotcha)
+## Dates & Timezones (Critical — three rules)
 
-`src/config/env.ts` sets `process.env.TZ = 'Europe/Prague'` and overrides
-`Date.prototype.toJSON()` to return local time (not UTC). This means:
+1. **Global override:** `src/config/env.ts` sets `TZ=Europe/Prague` and
+   monkey-patches `Date.prototype.toJSON()` to emit LOCAL time (PHP-migration
+   parity). All API date strings are local. Never assume UTC; never manually
+   offset. Do not remove the override.
+2. **`@db.Date` columns — Prisma truncates filter Dates to the UTC date
+   part.** A local-midnight boundary (`new Date(y, m, d)` = 22:00/23:00 UTC of
+   the _previous_ day) silently shifts the queried window a day back — this was
+   a 14-site production bug class. Build `@db.Date` filter boundaries and
+   "today" writes as UTC-midnight instants of the LOCAL calendar day:
+   `new Date(Date.UTC(y, m, d))` or `utcMidnightOfLocalDay()` from
+   `src/utils/date.ts`; use half-open `gte`/`lt` ranges; never write a bare
+   `new Date()` into a `@db.Date` column (stores yesterday between 00:00–02:00
+   Prague).
+3. **Two deliberate write regimes — don't "fix" either:** the plan module
+   does date-only math in UTC; attendance/leave writes `@db.Date` at **local
+   noon** (`new Date(y, m, d, 12, 0, 0)`). Frontend "today" comes from
+   `localDateStr` (server) / `normalizeDateStr`/`todayLocalStr` (client) —
+   **never** `new Date().toISOString().split("T")[0]` (UTC date, a day early
+   in the Prague evening).
 
-- `JSON.stringify(new Date())` returns local Czech time, not UTC.
-- All API responses with Date fields will contain local time strings.
-- Prisma stores dates as UTC internally, but they read back as local due to the TZ setting.
-- **Never assume UTC** when working with Date objects in this codebase.
-- When writing new date comparisons or DB queries, use `new Date()` (already local) — do not manually offset.
-- The override exists for PHP migration compatibility and Czech date display.

+
+## Document Modules (offers · orders · issued orders · invoices)
+
+**Business rules (user/accountant decisions — do not revert):**
+
+- **VAT exists ONLY on invoices and received invoices.** Offers, order
+  confirmations and issued orders are NOT tax documents: net prices only, one
+  total labeled "Celkem bez DPH" / "Total excl. VAT", no VAT columns, no
+  explanatory VAT notice. Their VAT DB columns were dropped. Invoices created
+  from an order prefill the company default VAT rate.
+- **Issued orders (objednávky vydané) take suppliers** (`sklad_suppliers`,
+  picker lookup at `GET /issued-orders/suppliers` under orders._ perms);
+  offers take customers. Issued orders share the `orders._` permission family
+  (deliberate).
+- **PDF families:** the offer PDF keeps its own monochrome customer-facing
+  design; invoices + issued orders share the red-accent (#de3a3a) family.
+- **Free-form PO content lives in the rich-text sections** ("Obsah" on issued
+  orders, "Rozsah projektu" on offers — CZ/EN titles, Quill content). Issued
+  orders deliberately have NO scope-template picker, NO item templates, NO
+  duplicate action.
+
+**Platform conventions:**
+
+- **Deferred numbering:** drafts carry a NULL document number
+  (nullable-unique column); the sequence number is consumed in-transaction on
+  finalize (draft→active / draft→sent) via `numbering.service.ts`, and
+  released-if-highest on delete. Never hardcode numbering; previews use the
+  collision-advancing helpers.
+- **Status machines:** `VALID_TRANSITIONS` maps in the services; detail
+  responses return `valid_transitions` and the UI renders transition buttons
+  from it. Field edits outside the editable states (offers: draft/active;
+  issued: draft/sent) are rejected with an explicit Czech 400 — status-only
+  payloads still pass.
+- **Edit locking:** lock/heartbeat/unlock route trio on both offers and
+  issued orders (30 s server TTL = 3 missed 10 s client heartbeats); detail
+  enriches `locked_by {user_id, username, full_name}` only when fresh and
+  held by another user; client side is the shared `useDocumentLock` hook +
+  `LockBanner`.
+- **PDF serving:** `GET …/:id/file` serves the archived NAS copy and falls
+  back to a live render (re-archiving it) on a miss; drafts 404 (no number),
+  so the UI hides PDF buttons on drafts. Numbered-document archives write to
+  a deterministic path and **overwrite in place** — never uniquePath `_N`
+  suffixes. The issued-order PDF gets language from the document's `language`
+  column and carries a Puppeteer `footerTemplate` footer on every page
+  ("Vystavil" left, "Strana X z Y"/"Page X of Y" centered) — Chromium has no
+  CSS margin-box footers; use `htmlToPdf(html, { footerTemplate })`.
+- **Shared modules — extend, never fork local copies:**
+  `src/admin/components/document/` (DocumentItemsEditor, SectionsEditor,
+  LockBanner), hooks `useDocumentLock` / `useUnsavedChangesGuard` /
+  `useDocumentPdf` (+ list variant), `src/admin/lib/documentStatus.ts`,
+  CustomerPicker/SupplierPicker, `src/utils/pdf-shared.ts` (escapeHtml,
+  strict cleanQuillHtml, formatNum NBSP, formatCurrency, formatDate),
+  `src/utils/content-disposition.ts` (RFC 5987 — raw filenames with
+  diacritics in headers make Node throw 500s).

 ## TOTP / 2FA
 
-- Secret stored AES-256-GCM encrypted in `users.totp_secret`.
-- Supports two encoding formats: PHP legacy (base64 iv+cipher+tag) and TS (hex).
-- Backup codes stored as encrypted JSON array in `users.totp_backup_codes`.
-- When `company_settings.require_2fa = true`, all users must enroll before accessing the app.
-- Login flow: password → if 2FA enabled → issue `loginToken` (5 min, single-use) → TOTP verify → issue access + refresh tokens.
+Secret AES-256-GCM encrypted in `users.totp_secret` (PHP-legacy base64 and TS
+hex formats both supported); encrypted backup codes with their own
+`/totp/backup-verify` login endpoint. `company_settings.require_2fa` forces
+enrollment. Login flow: password → (if enrolled) single-use 5-min
+`loginToken` → TOTP/backup verify → access + refresh tokens. The enrollment
+QR is generated locally with the `qrcode` package (never an external QR URL —
+CSP blocks it and it would leak the secret).

 ## Testing
 
-Tests live in `src/__tests__/`. They use Vitest + Supertest against a **real, throwaway test database** (`app_test`).
-
-- **Isolated test DB (`app_test`):** the suite MUTATES a real MySQL DB, so it runs against `app_test` (NOT dev `app`), configured in **`.env.test`** (gitignored). `src/__tests__/setup.ts` **hard-throws** if `DATABASE_URL` doesn't name a `*test*` database — a stray URL can never corrupt dev/prod data. To (re)create it: `CREATE DATABASE app_test;` → copy `.env` to `.env.test` with the DB name swapped + `ANTHROPIC_API_KEY=` blanked → `DATABASE_URL=<app_test-url> npx prisma migrate deploy` → `DATABASE_URL=<app_test-url> npx tsx prisma/seed.ts`.
-- The suite spans 18 files / 247 tests — auth (incl. happy-path login/refresh-rotation), numbering, warehouse (incl. FIFO oldest-first), plan, invoices, exchange-rates, schema coercion, NAS file manager, env, manual-create, AI/Odin, received-invoices VAT. Server-side only (no component tests yet).
-- Tests are now **type-checked** by `tsc -b` (via `tsconfig.test.json`) — keep them compiling.
-- Use `buildApp()` helper to spin up the Fastify instance for tests.
-- Tests use `vitest.config.ts` with `environment: 'node'` and 15s timeout; `fileParallelism: false` (serialized) to avoid `number_sequences` deadlocks.
-- **Do not mock Prisma** — tests hit a real database to catch schema/query bugs.
-
-When adding new features, add tests in `src/__tests__/`. Name test files `<feature>.test.ts`.
+- The suite MUTATES a real MySQL DB → it runs against **`app_test`** (never
+  dev `app`), configured in `.env.test`; `src/__tests__/setup.ts` hard-throws
+  unless `DATABASE_URL` names a `*test*` database.
+- **After any schema change, apply migrations to the test DB too** or the
+  suite fails: set `DATABASE_URL` to the app_test URL and run
+  `npx prisma migrate deploy`.
+- To (re)create it: `CREATE DATABASE app_test;` → copy `.env` to `.env.test`
+  with the DB name swapped + `ANTHROPIC_API_KEY=` blanked → migrate deploy →
+  `npx tsx prisma/seed.ts`.
+- **Do not mock Prisma** — real DB catches schema/query bugs. Mock only true
+  externals (Puppeteer via `vi.mock("../utils/html-to-pdf")`, NAS reads via
+  `vi.spyOn`). Files run serialized (`fileParallelism: false`) to avoid
+  sequence deadlocks. Tests are type-checked by `tsc -b`.
+- Fixture hygiene: far-future dates (year 2098) or unique prefixes + full
+  cleanup; FK-safe deletion order. New features get tests in
+  `src/__tests__/<feature>.test.ts`.

 ## Frontend Conventions
 
-- Pages are lazy-loaded via `React.lazy()` in `AdminApp.tsx`.
-- Auth state lives in `AuthContext`; use `useAuth()` hook to access it.
-- Alerts/toasts use `AlertContext`; use `useAlert()` to show them.
-- Data fetching uses **React Query** (query options + mutations in `src/admin/lib/queries/`); `src/admin/utils/api.ts` (`apiFetch`) handles token refresh automatically — dedupes concurrent refreshes, and token responses carry `expires_in` so the client refreshes BEFORE expiry (no reactive 401 churn).
-- Custom hooks: `usePaginatedQuery`, `useTableSort`, `useDebounce`, `useModalLock`, `useReducedMotion`.
-- Styling: **Material UI v7** (Emotion) — theme in `src/admin/theme.ts`, `sx`/`styled()` in components, app-wide rules in `GlobalStyles.tsx`. **No hand-written `.css` files, no Tailwind.** Use `theme.vars` for colours so light/dark resolve automatically.
+- Pages lazy-load via `React.lazy()` in `AdminApp.tsx`; auth via `useAuth()`,
+  toasts via `useAlert()`.
+- **React Query for all fetching** (query options live in
+  `src/admin/lib/queries/`; no fetch-in-useEffect; prefer deriving state over
+  effects). Mutations via `useApiMutation` (opt-in `envelope` mode passes the
+  server message through). `apiFetch` refreshes tokens proactively.
+- **Rules of Hooks:** every hook runs BEFORE any early return — the
+  `<Forbidden/>` guard goes after all hooks. Lint enforces this as an error.
+- **Invalidation:** broad domain keys (`["offers"]`, not `["offers","list"]`
+  — prefix matching covers sub-queries), and a mutation invalidates every
+  domain that embeds its data (user CRUD → trips+attendance; vehicle → trips;
+  invoice → orders; attendance/leave → **`["dashboard"]`**). The dashboard
+  also uses `refetchOnMount: "always"` as a backstop. Raw-`apiFetch` writes
+  still must invalidate their domains.
+- Single sources of truth: status chips/labels in `lib/documentStatus.ts`;
+  audit entity labels in `lib/entityTypeLabels.ts`; plan categories from the
+  DB. Don't duplicate label maps.
 
-### Query Invalidation Convention
+### Styling (MUI v7 — no custom .css, no Tailwind)
 
-Mutations must invalidate the **full domain** of any entity they touch. Prefer broad invalidation:
-
-- `["users"]` over `["users", "list"]`
-- `["trips"]` over `["trips", "vehicles"]`
-
-Reason: React Query's `invalidateQueries` uses prefix matching, so `["trips"]` matches all
-`["trips", ...]` sub-queries. This means new queries are automatically invalidated without
-updating every mutation handler. Inactive queries are only marked stale, not refetched, so
-the performance cost is minimal. Optimize to targeted keys only when profiling shows a problem.
-
-When entity A embeds/references entity B, A's mutation handlers invalidate B's domain:
-
-- User CRUD invalidates `["trips"]` and `["attendance"]` (both embed user data)
-- Vehicle CRUD invalidates `["trips"]` (trips reference vehicles)
-- Invoice CRUD invalidates `["orders"]` (orders reference invoices)
+- Theme in `src/admin/theme.ts` (cssVariables, light+dark schemes); global
+  rules in `GlobalStyles.tsx`; pages compose the kit in `src/admin/ui/` —
+  reach for raw `@mui/material` only for one-off layout/infra.
+- Colours via **`theme.vars!.palette.*`**; alpha via channel tokens
+  (`rgba(${theme.vars!.palette.primary.mainChannel} / 0.12)`); per-scheme
+  one-offs via `theme.applyStyles("dark", …)`. No hardcoded hex.
+- Don't regress: status row tints are channel-alpha washes (never `.light`
+  fills — invisible text in dark mode); icon badges are solid `X.main` +
+  white glyph; the theme persists ONLY under MUI's `mui-mode` localStorage
+  key (ThemeContext owns `<html data-theme>`); dialogs lock `<html>` via
+  `useDialogScrollLock`; Modal/ConfirmDialog freeze content through the close
+  fade; ConfirmDialogs stay open with `loading` during their request.
+- When refactoring pages, **preserve ALL data logic verbatim** (hooks,
+  mutations, invalidate arrays, validation, permissions).

-## Frontend — Styling & MUI (migration complete, shipped in v2.0.0)
+## AI Assistant — "Odin"
 
-The admin frontend is **fully on Material UI v7** (Emotion). The old ~7,100 lines of hand-written CSS are gone — **there are no custom `.css` files in `src/admin`**; the only stylesheets imported anywhere are the two third-party libs (`react-quill-new/dist/quill.snow.css`, `leaflet/dist/leaflet.css`). Look-and-feel is "Soft-SaaS shell + dense tables", dark/light preserved. Full history/decisions/gotchas live in agent memory (`project_mui_migration.md`); the original spec/plans are under `docs/superpowers/`.
+`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).
 
-**Where styling lives**
+**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).
 
-- **Theme — `src/admin/theme.ts`:** `cssVariables` with `colorSchemeSelector: "[data-theme='%s']"`, light + dark `colorSchemes`, tokens, component defaults. Use **`theme.vars!.palette.*`** (the `vars` field is typed optional → `!`) so colours resolve per scheme; for alpha use the channel tokens — `rgba(${theme.vars!.palette.primary.mainChannel} / 0.12)`; for per-scheme one-offs use `theme.applyStyles("dark", { … })`.
-- **Global rules — `src/admin/GlobalStyles.tsx`:** reset, typography, scrollbar, `::selection`, view-transition timing, and the utility classes (`.text-*`, `.flex-*`, `.mb-*`, …), all theme-aware. (The pre-React bootstrap spinner is inlined in `src/App.tsx` because it mounts before MUI.)
-- **Component kit — `src/admin/ui/`:** AppShell, Button, Card, TextField, Select (string-based — convert ids at the boundary), DateField/MonthField/TimeField (date-fns v4, cs), Modal, ConfirmDialog (optional `children` + content freeze), DataTable (sortable + mobile card layout + `rowSx`/`rowDanger`/`rowInactive`), Pagination, Tabs/TabPanel, StatusChip, CheckboxField/SwitchField, Field, Alert, PageHeader, FilterBar, StatCard, ProgressBar, FileUpload, EmptyState, LoadingState, ThemeToggle, PageEnter (staggered page entrance), RichEditorRoot/RichTextView (Quill). Dev-only `/ui-kit` showcase route.
-
-**Building / editing pages**
-
-- Pages import from the **kit** (`src/admin/ui/`); reach for `@mui/material` (`styled`/`sx`) directly only for one-off layout or infra (theme, GlobalStyles, the Quill/Leaflet wrappers).
-- Wrap a page's top-level sections in `<PageEnter>`. Filters go in `<FilterBar>` with **bare** controls (no `<Field>` label) at the standard widths.
-- When refactoring, **preserve ALL data logic verbatim** (hooks, mutations, `invalidate` arrays, validation, permissions); change only presentation.
-
-**Conventions learned — don't regress**
-
-- **Status row tints** = subtle channel-alpha washes (`rgba(var(--mui-palette-X-mainChannel) / 0.12)`), NEVER a solid `.light` fill: `.light` is a light colour in BOTH schemes, so white dark-mode text on it is invisible. Voided/disabled rows = `opacity` + muted text.
-- **Icon badges** = solid `X.main` tile + **white** glyph (not an `X.light` tile + `X.main` glyph — that's low-contrast).
-- **Theme is single-source:** `src/context/ThemeContext.tsx` owns the `<html data-theme>` attribute + the View-Transitions cross-fade, and persists under MUI's **`mui-mode`** localStorage key (the same key MUI reads on mount). Do NOT add a second theme key — that desyncs page vs toggle on refresh.
-- **Dialogs** lock `<html>` via `useDialogScrollLock` (MUI only locks `<body>`, and `html{overflow-x:hidden}` makes `<html>` the scroller); Modal/ConfirmDialog freeze title/label/loading through the close fade so nothing flashes. Login renders OUTSIDE AppShell.
-
-**Gates every change:** `npx tsc -b --noEmit` (NOT `-p tsconfig.json` — a vacuous solution file that checks nothing), `npm run build`, `npx vitest run`, `npm run lint`. The solution `tsconfig.json` now references `tsconfig.test.json` too, so `tsc -b` **type-checks the test files** (previously skipped). ESLint (flat config in `eslint.config.mjs`) enforces `react-hooks/rules-of-hooks` as an **error** — that rule catches the "hook after an early `return`" bug class; keep `npm run lint` at zero errors (warnings are advisory). Prettier config is `.prettierrc.json` (`npm run format`).
+Per-call cost ledger in `ai_usage` with a monthly budget cap (402 when
+exceeded). Invoice flow unchanged: PDF → `extract-invoices` (structured
+output) → review cards → existing `POST /received-invoices`.
+**`received_invoices.amount` is GROSS (VAT-inclusive)** — VAT is
+back-calculated (`vatFromGross`). Phase-2 design notes live in
+`docs/superpowers/specs/`.

-## AI Assistant — "Odin" (shipped v2.1.5)
+## Database & Migrations
 
-Admins-only Claude assistant on the `/odin` page (sidebar nav item "Odin"). **Phase-1 scope is invoice import ONLY** — general chat is guarded off in `OdinChat.submit` to avoid spending API credits: a text-only message gets a canned reply and makes NO AI call. Removing that one guard re-enables the `/chat` path for a later "general assistant" phase.
+Conventions: snake_case columns; `created_at`/`updated_at` timestamps;
+soft-delete via `is_deleted` where present; `number_sequences` owns all
+document numbering.
 
-- **SDK / model:** `@anthropic-ai/sdk` → `claude-sonnet-4-6`. Server-side only — `ANTHROPIC_API_KEY` in `.env` (already set on prod; **don't touch env, the user manages it**). The whole feature self-hides when the key is absent (`/ai/usage` returns `configured:false`).
-- **Backend:** `src/services/ai.service.ts` (chat, `extractInvoice` [PDF→structured-output JSON], cost/budget tracking, conversation CRUD with server-side auto-title), `src/routes/admin/ai.ts` (`/api/admin/ai/*`: usage, budget, chat, extract-invoices, conversations[/:id/messages]), `src/schemas/ai.schema.ts`. Every route `requirePermission("ai.use")` (granted to **admin only** via migration).
-- **Data:** `ai_usage` (per-call token-cost ledger), `ai_conversations` + `ai_chat_messages` (per-user, FK cascade, auto-title from first message), `company_settings.ai_monthly_budget_usd` (default $50; `assertBudgetAvailable` → 402 at the cap).
-- **Frontend:** `src/admin/pages/Odin.tsx` → `src/admin/components/odin/`: `OdinChat` (orchestrator + state + the proven submit/extract/save logic), `OdinSidebar` (conversation list; inline ≥md, slide-in Drawer below md), `OdinThread` (messages, framer-motion entrance, Newsreader serif greeting hero), `OdinComposer` (claude-style rounded multiline pill, attach/send icons), `InvoiceReviewCard`, `OdinMark` (animated brand mark — CSS keyframes via `styled`, not inline style; opacity-glow fallback under reduced-motion), `types.ts`. Queries in `src/admin/lib/queries/ai.ts`. `Fraunces`→`Newsreader` font added to `index.html`.
-- **Invoice flow:** attach PDF(s) → `extract-invoices` → editable review cards → save to the EXISTING `POST /received-invoices`. **`received_invoices.amount` is GROSS (VAT-inclusive)** — VAT is back-calculated via `vatFromGross` in `received-invoices.ts` (`amount * rate/(100+rate)`), used by both the manual form and the AI import. The save button is gated on `invoices.create`.
-- **Phase 2 (general assistant — NOT built):** forward-looking design notes in `docs/superpowers/specs/2026-06-08-odin-phase2-general-assistant-notes.md` (tool-use over services, structured message-block storage, per-action authorization). Phase-1 spec/plan also under `docs/superpowers/`.
+**Golden rules:**
 
----
+- **NEVER `prisma db push`** — it bypasses migration history and causes drift.
+- **Every DB change is a tracked migration** — schema, permission/seed rows,
+  backfills, one-shot fixes. A migration's `migration.sql` may contain plain
+  `INSERT/UPDATE/DELETE`. No raw SQL against production, ever; `prisma db
+seed` is dev-only convenience (`prisma/seed.ts` refuses to run with
+  `APP_ENV=production`) — prod baselines belong in migrations.
 
-## Database Conventions
-
-- All models use `snake_case` column names; Prisma maps to camelCase in TypeScript.
-- Soft-delete via `is_deleted` boolean (not all tables, check schema).
-- Timestamps: `created_at`, `updated_at` (auto-managed by Prisma).
-- Number sequences (`number_sequences` table) manage invoice/quotation numbering — never hardcode numbering logic.
-- All significant tables have audit log entries. Check `audit_logs` model for the schema.
-
----
-
-## Database Migrations (Critical Workflow)
-
-**Golden rule: NEVER use `prisma db push`.** It bypasses migration history and causes drift
-between the schema and migration tracking. Always use `prisma migrate dev` for every schema change.
-
-**Every database change or manipulation must be a tracked Prisma migration.** This includes:
-
-- Schema changes (tables, columns, indexes, constraints) — via `prisma migrate dev`
-- Permission/role/seed data changes — via a migration that does the INSERTs/DELETEs explicitly
-- Lookup data, default settings, or any other row-level baseline that production needs
-- Backfills, data fixes, and one-shot corrections that should be in sync across environments
-
-**What is NOT acceptable:**
-
-- Running raw SQL against production (`mysql -e "..."`, `npx prisma db execute`, `pm2 exec`)
-- `npx prisma db seed` as the only way to populate data (seed is dev-only convenience; prod must run the same SQL via a migration)
-- "I'll fix it in the seed file" or "I'll add a row manually" without a migration to back it
-
-The reason: every change to the production database must be reviewable, reversible, and reproducible from a fresh checkout. External SQL commands and seed-only changes cause drift — prod and dev diverge, rollback gets harder with every manual change, and the next deploy surprises us.
-
-If you need to insert/update/seed data on production, write a migration. The migration's `migration.sql` is a normal SQL file — `INSERT INTO ...`, `UPDATE ...`, `DELETE ...` are all valid. Prisma will run it via `prisma migrate deploy` like any other migration.
-
-### Making schema changes
-
-```
-1. Edit prisma/schema.prisma
-2. npx prisma migrate dev --name descriptive_name
-   → This creates a migration in prisma/migrations/ AND applies it to dev DB
-3. npx prisma generate
-4. Commit BOTH schema.prisma AND the new migration folder
-   git add prisma/schema.prisma prisma/migrations/
-```
-
-### Verifying before production deploy
+**Making a schema change (this shell is non-interactive — `prisma migrate
+dev` will refuse to run; use this recipe):**
 
 ```bash
-# Preview what SQL will run on production (no changes applied)
-npx prisma migrate diff \
-  --from-url "mysql://user:pass@prod:3306/app" \
-  --to-schema-datamodel prisma/schema.prisma \
-  --script
-
-# Empty output = no diff. If it shows SQL, review it before deploying.
+# 1. Edit prisma/schema.prisma   (ask the user to stop their dev server first!)
+# 2. Generate the migration SQL into a new folder:
+mkdir prisma/migrations/<yyyyMMddHHmmss>_<name>
+npx prisma migrate diff --from-config-datasource --to-schema prisma/schema.prisma --script \
+  > prisma/migrations/<...>/migration.sql        # strip the BOM if written via PowerShell Out-File!
+# 3. Review the SQL, then apply + regenerate:
+npx prisma migrate deploy
+npx prisma generate
+# 4. Apply to the test DB as well (suite breaks otherwise):
+#    DATABASE_URL=<app_test url> npx prisma migrate deploy
+# 5. Commit schema.prisma AND the migration folder together.
 ```
 
-### Deploying migrations to production
-
-The release process runs `prisma migrate deploy` on production.
-This applies only pending migrations — safe, idempotent.
-
-### If migrations get out of sync (drift)
-
-```bash
-# Diff production DB against local schema to find drift
-npx prisma migrate diff \
-  --from-url "mysql://prod" \
-  --to-schema-datamodel prisma/schema.prisma \
-  --script
-
-# If drift is safe (CREATE only, no DROPs): apply with db push ONCE, then baseline
-# If drift includes DROPs: investigate before touching production
-```
-
-### Baselinining a database that has no migrations
-
-If production was synced with `db push` and has no `_prisma_migrations` table:
-
-```bash
-# 1. Create initial migration locally
-npx prisma migrate dev --name init
-
-# 2. Copy to production and mark as applied (no SQL runs)
-scp -r prisma/migrations user@prod:/var/www/app-ts/prisma/
-ssh user@prod
-cd /var/www/app-ts
-npx prisma migrate resolve --applied <migration_name>
-```

-## Conventions (enforced — verified by the 2026-06-06 audit)
-
-These are the unified rules across the codebase. Follow them for new code; the
-audit found and fixed the deviations. Full report: `docs/codebase-audit-2026-06-06.md`.
+## Enforced Conventions (single source — merged 2026-06 audits)
 
 **Routes**
 
-- **Responses:** always `success(reply, data[, status, message])` / `error(reply, msg, status)` / the paginated helper. Never raw `reply.send({ success: true, ... })`. (Some legacy files still do — convert when you touch them.)
-- **Route ids:** parse numeric params with `parseId((request.params as any).id, reply)` then `if (id === null) return;`. Do not use raw `parseInt` (it yields `NaN`, not a 400).
-- **Bodies:** validate every body with `parseBody(Schema, request.body)` → `if ("error" in body) return error(reply, body.error, 400)`.
-- **Permissions:** guard with `requirePermission` / `requireAnyPermission`. The admin shortcut is `authData.roleName === "admin"`. ⚠️ `AuthData` has **`roleName`**, not `role` (`role` only exists on `JwtPayload`). Don't type `authData` as `any` — it hides exactly this bug.
-- **Audit:** call `logAudit` on every create/update/delete (and on security-relevant actions like session/token termination) with `oldValues`/`newValues`.
-
-**Services**
-
-- Plain exported async functions; return `{ data }` or `{ error, status }` (preferred over discriminated unions). Services own Prisma; routes stay thin.
-- Respect soft-delete (`is_deleted: false`) in reads where the model has it.
+- `success()`/`error()`/paginated helpers only; `parseId` for numeric params
+  (`if (id === null) return;`); `parseBody` for every body; permission guards
+  on reads AND writes; `logAudit` with old/new values on every mutation.
+- Role-management writes are admin-only and re-checked (no creating or
+  rewriting the `admin` role).
 
 **Schemas (Zod 4)**
 
-- Use Zod 4 idioms: `z.strictObject({...})` / `z.looseObject({...})` (not deprecated `.strict()` / `.passthrough()`).
-- Shared coercion helpers (number-from-form, nullable-number, boolean-from-form) belong in `src/schemas/common.ts` — don't copy-paste the `z.union([z.number(), z.string()]).transform(Number)` idiom (it's duplicated ~150× today; consolidating is a tracked follow-up). New number coercions should guard against `NaN`.
-- User-facing messages in **Czech**; identifiers/keys in English.
+- `z.strictObject`/`z.looseObject` (not deprecated `.strict()`/`.passthrough()`).
+- **Shared coercion helpers in `src/schemas/common.ts` are MANDATORY** for
+  form-coerced fields: `numberFromForm`, `numberInRange`,
+  `nonNegativeNumberFromForm`, `positiveNumberFromForm`,
+  `intIdFromForm`/`nullableIntIdFromForm`, `nonNegativeIntFromForm`,
+  `booleanFromForm`, `isoDateString`, `dateTimeString`/`nullableDateTimeString`,
+  `timeString`, `emailOrEmpty`, `DocumentSectionSchema`. NEVER the raw
+  `z.union([z.number(), z.string()]).transform(Number)` idiom (silent NaN —
+  the single biggest historical bug class). FK ids → intIdFromForm;
+  quantities/prices → nonNegative/positive; bounded → numberInRange.
+- The date/time helpers are deliberately **lenient** (strip trailing time
+  components) because edit forms re-submit `toJSON`-serialized values.
+  Optional emails: `emailOrEmpty.nullish()` (a bare `.email()` 400s the form).
+- Align `max()` caps with the DB column widths (an over-cap string 500s at
+  Prisma instead of 400ing at Zod). Update schemas derive via
+  `.partial()` (+ `.omit()` for immutable fields like document numbers) —
+  and therefore must NOT carry top-level `.default()`s (Zod 4 `.partial()`
+  still injects field defaults into partial payloads).
+- User-facing messages in **Czech**; identifiers/tokens in English.
 
-**Frontend**
+**Determinism & concurrency**
 
-- **Query invalidation:** invalidate the **broad domain key** (`["offers"]`, not `["offers","list"]`). Prefix-matching covers sub-queries.
-- **Single source of truth for shared maps:** audit `entity_type` → Czech label lives in `src/admin/lib/entityTypeLabels.ts` and MUST be keyed to the server's `EntityType` values (add the new key there when you add an entity type). Plan categories come from the DB via `lib/queries/plan.ts`. Don't duplicate label maps across files or across server/client.
-- Prefer deriving state over `useEffect`; use React Query for fetching, not effects.
+- Timestamp/date-only sorts ALWAYS get an `{ id }` tiebreak (second-precision
+  columns make single-key sorts non-deterministic).
+- Read-modify-write of shared rows (stock, balances, sequences) runs inside
+  `prisma.$transaction` with `SELECT … FOR UPDATE` via **`tx.$queryRaw`**
+  (not `$executeRaw`), locking in global ascending-id order. Multi-statement
+  writes (header + items + sections) belong in ONE transaction.
+- Uniqueness checks go INSIDE the create transaction (pass the `tx` client to
+  the checker) and catch `P2002` → 409 as backstop.
 
-**Dates (two deliberate regimes — don't "fix" either)**
+**Errors**
 
-- **Plan module** does all date-only math in **UTC** (`setUTCDate`, `toISOString().slice(0,10)`) because its columns are `@db.Date` (UTC-midnight). Correct and stable.
-- **Attendance/leave** writes `@db.Date` at **local noon** (`new Date(y, m, d, 12, 0, 0)`).
-- **Frontend "today" / date-string round-trips:** use `utils/date.ts` `localDateStr` (server) / `normalizeDateStr` (client). **Never** use `new Date().toISOString().split("T")[0]` for "today" — it's the UTC date and is a day early during the late-evening Prague window.
-
-## Conventions (enforced — added by the 2026-06-09 full audit)
-
-The 2026-06-09 file-by-file audit traced most bugs to a handful of patterns. These are now rules — `npm run lint` + `tsc -b` (which now type-checks tests) catch some automatically.
-
-**Zod validation — shared coercion helpers are MANDATORY**
-
-- All numeric/boolean/date/email form fields MUST use the helpers in **`src/schemas/common.ts`**: `numberFromForm`, `numberInRange(min,max)`, `nonNegativeNumberFromForm`, `positiveNumberFromForm`, `intIdFromForm`, `nullableNumberFromForm`/`nullableIntIdFromForm`, `booleanFromForm`, `isoDateString`, `timeString`, `emailOrEmpty`.
-- **NEVER** the raw `z.union([z.number(), z.string()]).transform(Number)` idiom — it silently yields `NaN` that flows into Prisma/business math (this was the single biggest bug class). FK ids → `intIdFromForm`/`nullableIntIdFromForm`; quantities/prices → `nonNegative`/`positive`; bounded values (VAT `0–100`, month `1–12`) → `numberInRange`.
-- `isoDateString`/`timeString` are **lenient** (they strip a trailing time/seconds component) because an edit form re-submits a `@db.Date` that the `toJSON` override serialised as `"YYYY-MM-DDT00:00:00"`. Use them for date/time fields, not a bare regex.
-- An optional email a form may submit as `""` → **`emailOrEmpty.nullish()`** (a bare `.email()` 400s the whole form, blocking unrelated saves).
-
-**Deterministic ordering — always tiebreak a timestamp sort with `id`**
-
-- `created_at`/`received_at` are **second-precision** (`@db.Timestamp(0)`/`DateTime(0)`), so `orderBy: { created_at: "desc" }` alone is non-deterministic for same-second rows. ALWAYS add `{ id: "desc" }` (or `asc`) as the secondary sort. (Bit `plan.service.resolveCell`/`resolveGrid` and warehouse FIFO `selectFifoBatches`.)
-
-**Concurrency — locking discipline for stock / balance / sequence mutations**
-
-- Any service op that read-modify-writes shared rows (stock, batches, reservations, balances, number sequences) MUST: run inside a `prisma.$transaction`; take the row lock with `SELECT … FOR UPDATE` via **`tx.$queryRaw`** (NOT `$executeRaw` — it does not reliably hold the lock); and lock rows in one global **ascending-id order** (parent → items → batches) so concurrent paths can't deadlock. See `warehouse.service.ts` `lockParentRow`/`lockRowsForUpdate` and `attendance.service.ts` `lockUserRow`.
-- **Uniqueness checks** (username/email/document number) go INSIDE the create transaction (re-check immediately before insert) and catch `P2002` → 409. A pre-transaction check is a TOCTOU race that surfaces as a 500.
-
-**Permissions — guard reads, not just writes**
-
-- GET list/detail endpoints need a `requirePermission`/`requireAnyPermission` guard, NOT bare `requireAuth` (bare-auth reads leak data to any logged-in user). Role-management writes are admin-only and re-checked (no privilege escalation; no creating/rewriting the `admin` role).
-
-**Frontend — Rules of Hooks (lint-enforced) + no UTC-today**
-
-- ALL hooks (`useState`, `useApiMutation`, `useMemo`, …) run BEFORE any early `return` (the `<Forbidden/>`/`<Navigate/>` permission guard goes AFTER every hook). `eslint.config.mjs` sets `react-hooks/rules-of-hooks` to **error** — `npm run lint` must stay at 0 errors. This was a systemic crash bug across ~14 pages.
-- Mutations invalidate the **broad domain key**; a mutation that writes via raw `apiFetch` must still `invalidateQueries` the domain it touched (several dashboard widgets were missing this).
-
-**Safety**
-
-- `prisma/seed.ts` **refuses to run when `APP_ENV=production`** (it wipes/reseeds permissions). Never seed prod.
-- Every catch logs (never silently swallow) — the NAS managers were the worst offenders.
+- Never silently swallow — every catch logs (`console.*` in services; there
+  is no request-scoped logger there). The only allowed silent catch is an
+  _expected_ condition (e.g. ENOENT-as-existence-check) **with a comment**.
+- Prefer explicit Czech 4xx over silently ignoring submitted fields.
 
 ---
 
-## Known Issues & Gotchas
+## Known Gotchas
 
-1. **Date.prototype.toJSON override** — global monkey-patch in `src/config/env.ts`. Side-effects on third-party libraries that serialize dates. Do not remove without migrating all date serialization.
-
-2. **CJS/ESM mismatch in tests** — Server compiles to CommonJS (`tsconfig.server.json`), but Vitest runs in ESM by default. The `vitest.config.ts` resolves this, but be careful when adding dependencies that only support ESM.
-
-3. **Mixed error patterns** — Some services return `{ error, status }`, others return discriminated unions `{ type: 'success' | 'error' }`. Prefer `{ error, status }` for consistency with existing routes.
-
-4. **Never swallow errors** — log at minimum; never use empty `catch` blocks. The service layer logs via `console.*` (there is no request-scoped pino logger in services). The NAS managers' previously-silent filesystem catches are now logged. One exception: a `catch` that handles an _expected_ condition (e.g. `ENOENT` used as an existence check) may stay silent **only with a comment** saying so.
-
-5. **HTML sanitization is in place — keep applying it** — Rich-text fields (invoice notes, quotation scope, order notes) ARE sanitized: server-side DOMPurify (jsdom) plus a `cleanQuillHtml` regex pass at all three PDF routes, and the frontend sanitizes before every `dangerouslySetInnerHTML` (InvoiceDetail, OrderDetail). (The old "sanitization gap" note was stale — verified by the 2026-06-06 audit.) When you add ANY new rich-text/HTML field, apply the same sanitization on BOTH the PDF path and the render path.
-
-6. **Puppeteer PDF generation** — Runs a headless browser. Input to the HTML template must be sanitized. Do not pass unsanitized user data into PDF templates.
-
-7. **NAS_PATH file access** — Project file uploads write to a network share path. In dev, this path may not be mounted. Features using `NAS_PATH` will fail gracefully (or not) if the path is unavailable.
-
-8. **Prisma client regeneration** — After any schema change and migration, run `npx prisma generate`. The generated client is not committed to git.
-
-9. **No CSRF tokens** — CSRF protection relies on `SameSite=Strict` cookies + CORS. Do not weaken CORS configuration.
-
-10. **Czech locale hardcoded** — Error messages, month names, and some business logic strings are Czech. This is intentional.
-
-11. **Seed file is dev-only** — `prisma/seed.ts` is for local dev convenience. It is **not** the production data source. Any data the production database must have (permissions, default roles, baseline rows) belongs in a migration's `migration.sql`, not in the seed file. `npx prisma db seed` must never be run against production.
+1. **CJS/ESM:** the server compiles to CommonJS; Vitest runs ESM
+   (`vitest.config.ts` bridges it). Beware ESM-only dependencies.
+2. **Rich text / PDF security:** every rich-text/HTML field gets server-side
+   DOMPurify + the strict `cleanQuillHtml` from `src/utils/pdf-shared.ts` on
+   the PDF path AND sanitization before any `dangerouslySetInnerHTML`. Never
+   pass unsanitized user data into Puppeteer templates; string-built HTML
+   (print views, PDF templates) must `escapeHtml` every interpolation.
+3. **NAS paths** may be unmounted in dev (`Z:`) — NAS features must degrade
+   with logged errors, and tests stub NAS reads.
+4. **Prisma client**: regenerate after every schema change; it is not
+   committed. (On prod this is a mandatory deploy step — see docs/release.md.)
+5. **No CSRF tokens** by design (SameSite=Strict + CORS) — do not weaken CORS.
+6. **Czech locale hardcoded** in messages/month names — intentional.
+7. **Cross-login caches:** React Query keys are user-agnostic; the query
+   cache is cleared on login/logout in AuthContext — keep it that way.

-## Release Process
+## Release
 
-1. Bump version in `package.json`
-2. `npm run build`
-3. Commit and tag (`git tag -a vX.Y.Z`)
-4. Push to Gitea (`git push origin master && git push origin vX.Y.Z`)
-5. Create tarball: `tar -czf app-ts-X.Y.Z.tar.gz dist dist-client prisma package.json package-lock.json scripts`
-6. Deploy via SSH to production server (`boha_admin@192.168.50.100`):
-   - Path: `/var/www/app-ts`
-   - Remove old files: `rm -rf dist dist-client prisma scripts package.json package-lock.json`
-   - Copy tarball to server: `scp app-ts-X.Y.Z.tar.gz boha_admin@192.168.50.100:/tmp/`
-   - Extract tarball: `tar -xzf /tmp/app-ts-X.Y.Z.tar.gz`
-   - Install dependencies: `npm install --omit=dev`
-   - Apply Prisma migrations: `npx prisma migrate deploy`
-   - Restart: `pm2 restart app-ts --update-env`
-
-### Hotfixing a migration that was added after the tarball was built
-
-If you write a new `prisma/migrations/<timestamp>_*` folder **after** the
-release tarball has already been built and shipped, that migration is
-NOT in the tarball and `prisma migrate deploy` on prod will report
-"No pending migrations". The release tarball re-build re-runs the whole
-release, but for a one-off hotfix you can ship just the new migration
-folder:
-
-```bash
-# Local
-cd prisma/migrations
-tar -czf /tmp/warehouse_perms_migration.tar.gz <timestamp>_<name>/
-scp /tmp/warehouse_perms_migration.tar.gz boha_admin@192.168.50.100:/tmp/
-
-# On prod
-ssh boha_admin@192.168.50.100
-cd /var/www/app-ts/prisma/migrations
-sudo -u boha_admin tar -xzf /tmp/warehouse_perms_migration.tar.gz
-cd /var/www/app-ts
-npx prisma migrate deploy
-pm2 restart app-ts --update-env
-```
-
-The migration is still tracked in git and applied via `prisma migrate
-deploy` — the only thing the tarball is doing is delivering the
-`migration.sql` to prod, which is the same mechanism the main release
-uses. This is preferred over running raw SQL on prod (which the policy
-in "Database Migrations" forbids).
-
-Do not push directly to production or restart services without confirmation.
+Process, deployment commands, hotfix-migration shipping and verification
+checklist: **`docs/release.md`**. Run the full test suite before tagging; the
+user picks version numbers. **Never push to production or restart services
+without explicit confirmation.**

-# 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 |
-
----
-
-## Quick Reference
-
-| Command | Purpose |
-|---------|---------|
-| `pm2 start ecosystem.config.js` | Start the app |

+# Release & deployment runbook — boha-app-ts
+
+Referenced from CLAUDE.md. **Never deploy to production or restart services
+without explicit user confirmation.**
+
+## Standard release
+
+1. Run the full gates locally: `npx vitest run` (all green), `npx tsc -b --noEmit`,
+   `npm run lint` (0 errors).
+2. Bump version: `npm version X.Y.Z --no-git-tag-version` (the user picks the number).
+3. `npm run build`
+4. Commit and tag: `git tag -a vX.Y.Z`
+5. Push to Gitea: `git push origin master && git push origin vX.Y.Z`
+6. Create tarball:
+
+   ```bash
+   tar -czf app-ts-X.Y.Z.tar.gz dist dist-client prisma prisma.config.ts package.json package-lock.json scripts
+   ```
+
+   ⚠️ `prisma.config.ts` is REQUIRED — Prisma 7 keeps the datasource URL there;
+   without it, `prisma generate`/`migrate deploy` on prod have no datasource.
+
+7. Deploy via SSH to production (`boha_admin@192.168.50.100`, path `/var/www/app-ts`):
+
+   ```bash
+   scp app-ts-X.Y.Z.tar.gz boha_admin@192.168.50.100:/tmp/
+   ssh boha_admin@192.168.50.100
+   cd /var/www/app-ts
+   rm -rf dist dist-client prisma prisma.config.ts scripts package.json package-lock.json
+   tar -xzf /tmp/app-ts-X.Y.Z.tar.gz
+   npm install --omit=dev
+   npx prisma generate        # MANDATORY — see below
+   npx prisma migrate deploy
+   pm2 restart app-ts --update-env
+   ```
+
+   **`npx prisma generate` is mandatory.** `npm install` skips client
+   regeneration when dependencies didn't change, leaving a stale client that
+   still selects dropped/renamed columns → P2022 500s in prod (this caused
+   the v2.4.0 incident: every issued-orders query failed until generate ran).
+
+8. Verify: `pm2 list` (status online, correct version, restart counter not
+   climbing), `npx prisma migrate status` ("up to date"),
+   `curl -s -o /dev/null -w '%{http_code}' http://127.0.0.1:3001/` → 200,
+   and grep logs for errors from the CURRENT pid only (the out log keeps old
+   errors from prior pids).
+9. Clean up tarballs locally and in `/tmp/` on the server.
+
+Risky releases (framework jumps, FK/constraint-altering migrations) get a
+read-only pre-flight first: `prisma migrate status` on prod, verify FK
+constraint names the migration DROPs, check no data violates new
+UNIQUE/RESTRICT constraints — and confirm with the user before the
+irreversible steps. The prod DB is backed up by a cron job (no manual
+mysqldump needed).
+
+## Hotfixing a migration added after the tarball was built
+
+A migration folder created after the release tarball shipped is not on prod,
+so `prisma migrate deploy` reports "No pending migrations". Ship just the
+migration folder (still tracked in git — this is NOT raw SQL on prod):
+
+```bash
+# Local
+cd prisma/migrations
+tar -czf /tmp/<name>_migration.tar.gz <timestamp>_<name>/
+scp /tmp/<name>_migration.tar.gz boha_admin@192.168.50.100:/tmp/
+
+# On prod
+ssh boha_admin@192.168.50.100
+cd /var/www/app-ts/prisma/migrations
+tar -xzf /tmp/<name>_migration.tar.gz
+cd /var/www/app-ts
+npx prisma migrate deploy
+pm2 restart app-ts --update-env
+```
+
+## Drift check / preview before deploy
+
+```bash
+# Preview what SQL would bring the dev DB (per prisma.config.ts) to the local schema
+npx prisma migrate diff --from-config-datasource --to-schema prisma/schema.prisma --script
+```
+
+Empty output = no diff. (Prisma 7 removed `--from-url`; diffs against another
+DB need its URL in a config/env override.) If drift includes DROPs,
+investigate before touching production.
+
+## Baselining a database that has no migrations
+
+If a database was synced without migration history (no `_prisma_migrations`
+table): create the initial migration locally, copy `prisma/migrations` to the
+server, then mark it applied without running SQL:
+
+```bash
+npx prisma migrate resolve --applied <migration_name>
+```

+# 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.
+

+# 2026-06-10 — Audit fix pass #1: all verified CRITICAL/HIGH findings
+
+Source: `REVIEW_FINDINGS.md` (2026-06-09 full audit, 304 files). Scope of this pass:
+the 19 verified per-file **HIGH** findings + the project-level **CRITICAL** dependency
+finding. The two project-level HIGH _structural refactors_ (service-layer extraction for
+6 route files; PDF template dedup) are explicitly **out of scope** — they are
+multi-thousand-line refactors that deserve their own pass.
+
+Execution: subagent-driven development — one implementer per task (sequential, shared
+test DB forbids parallel test runs), spec-compliance review then code-quality review
+after each. No commits until the user asks. Final full gates:
+`npx tsc -b --noEmit` · `npx vitest run` · `npm run lint` · `npm run build`.
+
+---
+
+## Task H — Dependencies (project-level CRITICAL) — done inline by controller
+
+- Remove `concurrently` from devDependencies (unused; carries both critical advisories
+  GHSA-w7jw-789q-3m8p / shell-quote CVSS 8.1).
+- Add `"overrides": { "@hono/node-server": "^1.19.13" }` (clears the 3 moderate
+  advisories from the prisma → @prisma/dev chain; do NOT take npm's Prisma 6 downgrade).
+- Remove deprecated stub types `@types/dompurify`, `@types/bcryptjs`; move `@types/jsdom`
+  to devDependencies.
+- Add `qrcode` + `@types/qrcode` (needed by Task B to replace the CSP-blocked external
+  QR service).
+- `npm install`, verify `npm audit` (criticals+moderates gone), typecheck.
+
+## Task A — Attendance create/edit broken since 519edce (top-5 #1)
+
+Findings (both verified HIGH):
+
+- `src/admin/pages/AttendanceCreate.tsx: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" would reach
+  createAttendance which does `new Date('08:00')` → Invalid Date → 500; 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.
+- `src/admin/pages/AttendanceAdmin.tsx:407-442` (logic in `useAttendanceAdmin.ts`) —
+  create/edit modal submits send combined `YYYY-MM-DDTHH:MM:00` datetimes for
+  arrival/departure/break, but since 519edce 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(...)`); additionally `break_start`/`break_end` are absent from
+  CreateAttendanceSchema, so breaks are silently stripped on create.
+
+Direction: first `git show 519edce` to understand the intent; the schema contradicts
+both client and service, so the fix is to make the schemas validate the combined
+local-datetime wire format the client sends and the service consumes (lenient helper in
+`src/schemas/common.ts` per repo convention), add `break_start`/`break_end` to the create
+schema, and rewrite AttendanceCreate.tsx's submit to combine date+time and omit empty
+optionals. TDD: route-level regression tests (work record with times+breaks, overnight,
+leave record without times, update) in `src/__tests__/`.
+
+## Task B — 2FA: backup-code login, enrollment QR, dashboard status (top-5 #2)
+
+Findings (all verified HIGH):
+
+- `src/admin/context/AuthContext.tsx:263-272` — backup-code login broken: verify2FA
+  always POSTs to /login/totp with the code as totp_code plus an isBackup flag the server
+  ignores; TotpVerifySchema requires exactly 6 digits so 8-char backup codes always 400.
+  The real endpoint POST /api/admin/totp/backup-verify (expects backup_code) is never
+  called anywhere in the frontend — lockout for any user who lost their authenticator.
+- `src/admin/components/dashboard/DashProfile.tsx:556` — QR `<img>` from api.qrserver.com
+  is blocked by the production CSP (img-src 'self' data: blob: + osm tiles), so prod 2FA
+  enrollment shows a broken image. (Also a privacy bug: the TOTP secret is sent to a
+  third-party URL.) Fix: generate the QR locally with the `qrcode` package
+  (`QRCode.toDataURL(otpauthUrl)`) — data: is already CSP-allowed.
+- `src/admin/pages/Dashboard.tsx:89-91` — totpEnabled derived from require2FAOptions()
+  which returns the COMPANY-WIDE require_2fa policy flag, not the user's enrollment; the
+  per-user endpoint (totp.ts:190-197) is never queried. Wrong "2FA Aktivní/Neaktivní" and
+  wrong button shown.
+
+Direction: read `src/routes/admin/totp.ts` first; wire Login/AuthContext so a backup code
+goes to backup-verify and completes the login-token flow. If the server endpoint doesn't
+fit the loginToken flow, extend it minimally (single-use code consumption + logAudit
+preserved). Server test for backup-verify login path if server is touched.
+
+## Task C — Invoice/issued-order edit integrity (top-5 #3)
+
+Findings (all verified HIGH):
+
+- `src/admin/pages/InvoiceDetail.tsx:728` — edit hydration overwrites each item's
+  persisted per-line VAT with the invoice-level rate (`vat_rate: Number(inv.vat_rate) || 21`)
+  though invoice_items.vat_rate is a real per-item column — re-saving a mixed-rate invoice
+  silently corrupts per-line VAT in the DB; `|| 21` also turns legitimate 0% into 21%
+  (same falsy-zero at line 689).
+- `src/admin/pages/InvoiceDetail.tsx:1891-1902` — editing "Text fakturace (na PDF)" is
+  silently lost: payload includes billing_text but UpdateInvoiceSchema
+  (src/schemas/invoices.schema.ts:46-67) has no billing_text field, so Zod strips it
+  (updateInvoice supports it via strFields). Add the field to the schema + server test.
+- `src/admin/pages/IssuedOrderDetail.tsx:606-611` — hydration falsy-fallbacks:
+  `quantity: Number(it.quantity) || 1` turns saved 0 into 1; `vat_rate: Number(it.vat_rate)
+|| Number(d.vat_rate) || 21` turns a saved 0% line into 21% — displayed wrong and
+  silently persisted on next save.
+- `src/admin/pages/IssuedOrderDetail.tsx:826-839` — handleStatusChange never mirrors the
+  new status into form.status, so StatusChip, the `editable` flag and the delete-button
+  gate use the stale status after every transition.
+
+Use Number.isFinite-style coercion that respects 0 (e.g. `const n = Number(x);
+Number.isFinite(n) ? n : fallback`).
+
+## Task D — Trips: truncated lists/totals + dropped vehicle edit (top-5 #4a)
+
+Findings (all verified HIGH):
+
+- `src/admin/lib/queries/trips.ts:52-63` — tripListOptions consumes the paginated
+  endpoint via plain jsonQuery, discarding pagination meta; Trips.tsx uses default limit
+  25 and TripsAdmin perPage:100 (server hard cap) — both silently truncate with no
+  pagination controls.
+- `src/admin/lib/queries/trips.ts:95-103` — tripHistoryOptions sends no page/per_page →
+  25 rows; TripsHistory.tsx computes monthly km/business totals from the truncated rows.
+- `src/admin/pages/Trips.tsx:324-336` — stat cards computed from the 25-row page;
+  header labels stats "current month" though the query has no month filter.
+- `src/admin/pages/TripsAdmin.tsx:295,665-676` — edit modal sends vehicle_id but
+  UpdateTripSchema (src/schemas/trips.schema.ts:23-31) has no vehicle_id and the PUT
+  handler never applies it — vehicle change silently dropped. Add to schema
+  (nullableIntIdFromForm) + apply in route + audit + server test.
+- `src/admin/pages/TripsHistory.tsx:98-104,121-128` — same 25-row truncation for the
+  month view and its stat cards.
+
+Direction for totals: prefer a server-side aggregate (the repo already has per-currency
+totals endpoints for invoices/orders as the pattern) over fetching all pages client-side;
+lists get real pagination using the existing `usePaginatedQuery`/`Pagination` kit pieces
+used elsewhere. Keep the month-filter semantics of TripsHistory correct (totals must
+cover the WHOLE month, not one page).
+
+## Task E — orders.service.ts: PDF blob in every response (top-5 #4b)
+
+Finding (verified HIGH): `src/services/orders.service.ts:154-176,196-216,228-263,570,683`
+— attachment_data (full PDF blob, Bytes) is fetched on every query with no select/omit
+and spread into API responses by enrichOrder/getOrder; getOrderTotals loads every blob
+for the whole filtered set just to sum totals; updateOrder/deleteOrder pre-reads pull the
+blob to check status/number. A dedicated /:id/attachment endpoint already exists.
+Exclude the blob from list/detail/totals/pre-reads (keep has_attachment-style boolean if
+the FE needs it — check FE usage), keep the attachment endpoint working, extend
+`src/__tests__/orders-list.test.ts` to assert attachment_data is absent.
+
+## Task F — Warehouse: unit enum 400s + dead attachment download
+
+Findings (both verified HIGH):
+
+- `src/admin/pages/WarehouseItemDetail.tsx:451-462` — "Jednotka" is free-text but the
+  server requires UnitEnum ("ks","m","kg","bal","sada","m2","m3","l") — any other value
+  400s create/update. Make it a Select over the enum values (single source: mirror the
+  server enum list).
+- `src/admin/pages/WarehouseReceiptDetail.tsx:251-259` — attachment link targets
+  GET /warehouse/receipts/:id/attachments/:attachmentId which does not exist (only POST
+  upload + DELETE are registered in warehouse.ts), and a plain <a href> sends no
+  Authorization header anyway. Add the GET download route (requirePermission, correct
+  content-type/disposition) + authenticated blob download in the UI (fetch via apiFetch →
+  object URL, like other binary downloads in the repo). Server test for the new route.
+
+## Task G — Small fixes
+
+- `.claude/hooks/block-env.js:10-11` (verified HIGH) — block decision never takes
+  effect: 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 on stderr). Fix: exit 2 with the
+  reason on stderr.
+- `src/admin/pages/Projects.tsx:153-154` (verified HIGH) — create modal submits
+  start_date/end_date initialized to "" which isoDateString.nullish() rejects → creating
+  a project without filling BOTH dates always 400s. Send null/omit when empty.
+
+---
+
+## Status
+
+- [x] H — dependencies (controller, inline) — criticals+moderates cleared; only the
+      2 known-mitigated quill lows remain
+- [x] A — attendance create/edit — dateTimeString helpers, break fields, rewritten
+      AttendanceCreate payload; 6 regression tests

+      (buildTripsWhere shared), vehicle_id on PUT + both-vehicle odometer recompute,
+      print rebuilt (sync window.open, escaped string template); 7 tests
+- [x] E — orders attachment_data excluded from all non-binary reads (incl.

+# 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

+
+---
+
+## Audit Entity Types
+
+New values added to `EntityType` union in `src/types/index.ts`:
+
+- `warehouse_item`
+- `warehouse_receipt`
+- `warehouse_issue`
+- `warehouse_reservation`
+- `warehouse_inventory`
+- `warehouse_supplier`
+- `warehouse_category`
+- `warehouse_location`
+
+---
+
+## 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
+  numbering exhaustion (the `generateSharedNumber` 100-retry throw → mapped to a
+  500 with a Czech message by the route, logged via `app.log.error`).
+- NAS folder creation is non-fatal and logged (never blocks creation).
+
+## Out of scope (v1) — noted for later
+
+- 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).
+- Manual project-number override (user chose auto-from-pool).
+- A unified order+project number lookup/search.
+
+## Affected files (summary)
+
+- `src/schemas/projects.schema.ts` (add `CreateProjectSchema`)
+- `src/schemas/orders.schema.ts` (add `create_project`)
+- `src/services/projects.service.ts` (add `createProject`)
+- `src/services/orders.service.ts` (`createOrder` optional project)
+- `src/routes/admin/projects.ts` (`POST /`, `GET /next-number`)
+- `src/routes/admin/orders.ts` (audit project on manual order)
+- `src/admin/pages/Projects.tsx` (+ create modal, badge, empty-state)

+# 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.
