+## AI Assistant — "Odin" (shipped v2.1.5)
+
+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.
+
+- **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/`.

+## 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.

+# boha-app-ts
+
+Internal business-management system for a Czech company (attendance, invoicing,
+leave/trips, projects, vehicles, warehouse, HR) — a TypeScript/Node.js rewrite
+of the legacy PHP app. User-facing text is Czech by design.
+
+> For full architecture, conventions, and gotchas, see **[CLAUDE.md](./CLAUDE.md)**.
+
+## Stack
+
+- **Backend:** Fastify 5 · Prisma 6 → MySQL · Zod 4 · JWT (HS256) + TOTP 2FA
+- **Frontend:** React 18 · Vite · Material UI v7 (Emotion) · TanStack Query — an
+  SPA in `src/admin/`, served by the same Fastify process (Vite middleware in
+  dev, static files in prod)
+- **Other:** Puppeteer (PDF) · nodemailer · node-cron · `@anthropic-ai/sdk` (the
+  admins-only "Odin" assistant)
+
+## Prerequisites
+
+- Node.js (LTS) and a MySQL database
+- Copy `.env.example` → `.env` and fill in the **required** vars (`DATABASE_URL`,
+  `JWT_SECRET`, `TOTP_ENCRYPTION_KEY` — generate the keys with `openssl rand -hex 32`)
+
+## Setup
+
+```bash
+npm install
+npx prisma generate
+npx prisma migrate dev      # apply migrations to your dev DB
+npx prisma db seed          # optional: dev-only sample data (NEVER on prod)
+```
+
+## Develop
+
+```bash
+npm run dev:server   # API (tsx watch) on http://127.0.0.1:3050
+npm run dev:client   # Vite dev server (manage separately)
+```
+
+## Build & run
+
+```bash
+npm run build        # tsc server → dist/  +  vite client → dist-client/
+npm start            # node dist/server.js
+```
+
+## Test
+
+```bash
+npm test             # vitest run — hits a real test DB (.env.test); no Prisma mocks
+```
+
+## Quality gates
+
+Before committing, all of these must pass:
+
+```bash
+npx tsc -b --noEmit  # typecheck (NOT `tsc -p tsconfig.json`)
+npm run build
+npx vitest run
+npm run lint         # ESLint (incl. react-hooks) — see eslint.config.js
+```
+
+## Database migrations
+
+Every schema/data change is a tracked Prisma migration — **never** `prisma db push`
+or raw SQL on production. Stop the dev server before running `prisma migrate dev`.
+See CLAUDE.md → _Database Migrations_ for the full workflow and the production
+deploy/hotfix process.

+# Cross-Module Consistency Report: Offers, Invoices, Orders
+
+> Generated 2026-06-09 by a multi-agent UI/UX audit (4 by-dimension examiners + synthesis)
+> across the Offers (nabídky), Invoices (faktury), and Orders (objednávky) modules.
+> Examination only — no code was changed. File:line refs are at the time of the audit.
+
+## 1. Executive Summary
+
+The three document modules (Offers, Invoices, Orders) share a strong common foundation — `PageEnter`/`PageHeader`/`Card`/`FilterBar`/`DataTable`/`StatusChip`/`Pagination`, a near-identical line-item editor (dnd-kit drag, mobile cards, monospace per-row totals, per-rate VAT breakdown), and a uniform totals layout — so the divergences are concentrated in a handful of presentational and behavioral details rather than the architecture. **No single module is canonical across the board:** Invoices is the most mature on list-level intelligence (KPI StatCards, overdue row tinting) and is the only one with a polished load pattern (ReceivedInvoices' `hasLoadedOnce` skeleton suppression); Issued Orders is the cleanest detail-page reference (single editable form with a `readOnly` prop, semantically correct status-transition button colors); and Offers is the best on list-level state richness (three-tier `rowSx` tinting, search-aware empty states) but the worst on detail-form fidelity (raw HTML checkboxes, action-icon overload). The highest-value work clusters into four buckets: bring Orders up to Invoices' list intelligence (KPIs, filters, row tinting), converge the three detail forms on shared MUI kit components (Autocomplete customer picker, MUI Checkbox, RichEditor notes), fix two genuine safety/feature bugs (delete-button guards and Orders' missing delete), and a long tail of cheap label/width/alignment unifications in the line-item tables.
+
+## 2. Recommended Canonical Patterns
+
+| Dimension                       | Standardize on                                                                               | Why                                                                                        |
+| ------------------------------- | -------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------ |
+| List KPI cards                  | **Invoices** (`Invoices.tsx:420-505`)                                                        | Only module with a 4-card metrics grid; gives business context Orders/Offers lack          |
+| List load/skeleton              | **ReceivedInvoices** (`hasLoadedOnce` ref, lines 325/688/784)                                | Skeleton only on first mount, suppressed on refetch — no full-page blocking jank           |
+| List row state tinting          | **Offers** (`Offers.tsx:650-684`) three-tier `rowSx`                                         | Richest at-a-glance lifecycle signal; Invoices' single overdue tint is the minimal version |
+| List status filter              | **Tabs** for ≤4 states (Offers/Invoices), **Select** for ≥5 (IssuedOrders)                   | Tabs show all options inline; Select scales — choose by option count                       |
+| Search-aware empty state        | **Offers** (`Offers.tsx:840-855`)                                                            | Distinguishes search-empty (no CTA) from list-empty (with CTA)                             |

+
+## 3. Inconsistencies by Dimension
+
+### A. Tables & Lists
+
+**HIGH — Orders lack KPI StatCards.** Invoices renders a 4-card metrics grid (`Invoices.tsx:420-505`; ReceivedInvoices `:687-761`); IssuedOrders, OrdersReceived, and Offers render none. Orders users lose pipeline visibility (count by status, total value). Fix: add a 4-StatCard grid to IssuedOrders/OrdersReceived mirroring the Invoices layout. Decide whether Offers warrants its own. Effort: **M**.
+
+**HIGH — Offers row-action overload (6-7 icons vs 3).** `Offers.tsx:540-641` renders View/Edit, Duplicate, Show/Create Order, Invalidate, PDF, Delete; Invoices/IssuedOrders/OrdersReceived keep 3. Fix: reduce Offers to 4 (View/Edit, Order toggle, PDF, Delete); move Duplicate/Invalidate into a row overflow menu or the detail page. Effort: **M**.
+
+**MED — Orders missing list features that Invoices/Offers have.**
+
+- _Row state tinting:_ Offers 3-tier (`:650-684`), Invoices 1-tier overdue (`:510-526`), all three Orders modules + ReceivedInvoices = none. Add `rowSx` (completed→success wash, overdue/expired→warning, voided→opacity) using the channel-alpha convention. Effort: **S** each.
+- _Status filter:_ OrdersReceived has none; add a Select like IssuedOrders (`:305-313`, `STATUS_OPTIONS` `:53`). Effort: **S**.
+- _Sortable columns:_ IssuedOrders/OrdersReceived expose only 3 `sortKey`s vs 5-6 in Invoices/Offers; add customer_name, total, status. Effort: **S**.
+
+**MED — Load pattern blocks the page on refetch.** Offers (`:453`), Invoices (`:402`), IssuedOrders (`:189`), OrdersReceived (`:328`) return a full `<LoadingState/>` whenever `isPending`; only ReceivedInvoices suppresses the skeleton after first load (`hasLoadedOnce`, `:325/688/784`). Adopt the `hasLoadedOnce` ref pattern everywhere. Effort: **S-M**.
+
+**MED — Amount column label split.** ReceivedInvoices uses "Částka"; everyone else "Celkem". Rename "Částka"→"Celkem". (supplier-vs-customer terminology "Dodavatel"/"Zákazník" is correctly domain-specific — leave it.) Effort: **S**.
+
+**LOW — Offers tabs not centered.** Invoices/Orders wrap Tabs in a centered Box (`Invoices.tsx:712-721`, `Orders.tsx:161-170`); Offers (`:717-726`) left-aligns. Effort: **S**.
+
+**LOW — Empty-state copy not search-aware.** Offers distinguishes search-empty vs list-empty (`:840-855`); the others show one message (+ stale CTA when filtered to empty). Effort: **S**.
+
+_Already fine: PageHeader, FilterBar layout, Pagination placement, StatusChip colors, search-placeholder copy, draft-banner presence (Offers/Invoices by design)._
+
+### B. Detail Buttons & Layout
+
+**HIGH — Delete-button safety bugs + Orders feature gap.**
+
+- OfferDetail (`:1191-1199`) allows delete even when invalidated/locked/completed.
+- InvoiceDetail (`:1167-1175`, `:1734-1742`) allows delete even when `paid`.
+- IssuedOrderDetail has **no delete at all** (no button/mutation/handler).
+  Fix: add `!readOnly`/status guards to Offers and Invoices; add a guarded delete to IssuedOrderDetail for parity. Effort: **M**.
+
+**HIGH — Detail read-only handling diverges.** IssuedOrderDetail uses one form with a `readOnly`/`editable` flag (`:638`); InvoiceDetail forks a whole separate read-only JSX branch for paid invoices (`:1104-1615`) that must be hand-synced; OfferDetail is always editable. Fix: refactor InvoiceDetail's paid view to the single-form-`readOnly`-prop model. Effort: **L**.
+
+**MED — Status-transition button styling inverted.** InvoiceDetail emphasizes positive ("paid"→`contained`+`primary`, `:1719-1733`); IssuedOrderDetail emphasizes danger ("cancelled"→`outlined`+`error`, `:903-917`). Standardize on the Order rule. Effort: **S**.
+
+**MED — Back-button target inconsistent.** OfferDetail→`/offers` (`:1108`), InvoiceDetail→`/invoices` (`:1124`/`:1639`), IssuedOrderDetail→`/orders?tab=vydane` (`:836`). Make tabbed-landing modules carry the tab param: Invoices→`/invoices?tab=issued`. Effort: **S**.
+
+**LOW — Save-button loading style.** Offers text-only (`:1187`); Invoice/Order spinner+text. Switch Offers to spinner+text. Effort: **S**.
+
+**LOW — Create-success invalidation scope.** OfferDetail invalidates `["offers","orders","projects","invoices"]` (`:927`); Invoice/Order invalidate only their own domain. Verify Invoice/Order touch no foreign domains, else widen. Effort: **S**.
+
+**LOW — Guard placement.** Hoist Invoice/Order `if (!dataReady)` guards to OfferDetail's top-level pattern when touching those files. Effort: **S**.
+
+_Already fine: PageEnter wrapper, header layout + `headerActionsSx`, StatusChip-in-header, mobile breakpoints, Card sectioning, items-table structure, totals block, permission guards._
+
+### C. Forms & Fields
+
+**HIGH — Customer/supplier picker: 3 different widgets.** Offers (`OfferDetail.tsx:1307-1373`) and Invoices (`InvoiceDetail.tsx:1816-1876`) use a hand-rolled searchable dropdown; IssuedOrders (`:935-948`) uses a plain non-searchable `<Select>`; ReceivedInvoices (`:914-929`) uses MUI `Autocomplete freeSolo`. Standardize all on `Autocomplete freeSolo`. Effort: **M**.
+
+**HIGH — `apply_vat` boolean: MUI Checkbox vs raw `<input>`.** Offers uses MUI `Checkbox` (`:1482-1488`); InvoiceDetail (`:2008-2017`) and IssuedOrderDetail (`:1023-1035`) use raw `<input type="checkbox">`. Standardize on the kit `CheckboxField`. Effort: **S**.
+
+**HIGH — Notes field: TextField vs RichEditor.** Offers (`:1953-1966`) and Orders (`:1257-1272`) use RichEditor; Invoices (`:2232-2240`) and ReceivedInvoices modal (`:1214-1225`) use plain multiline TextField. Move Invoices notes to RichEditor — and per CLAUDE.md gotcha #5, apply DOMPurify + `cleanQuillHtml` sanitization on both the PDF and render paths. Effort: **M**.
+
+**MED — `issued_by` editable in Orders, read-only in Invoices.** Make Orders read-only + auto-filled from auth. Effort: **S**.
+
+**MED — VAT rate/toggle layout differs.** Adopt Offers' dual-field (rate Select + toggle) where a per-document rate applies. Effort: **M**.
+
+**LOW — Currency options hard-coded in Orders.** IssuedOrders (`:96-99,985`) and OrdersReceived modal (`:575-580`) hard-code; point at company settings. Effort: **S**.
+
+_Already fine: `<Field>` wrapper + error display, DateField usage, totals footer, Card grouping, basic-info grid, delivery/payment terms being Orders-only (domain-justified)._
+
+### D. Line-Item Editors
+
+Offers is the consistent outlier; Invoices+Orders already agree — canonicalize on them. Cheap, mostly-mechanical edits in `OfferDetail.tsx` (plus one internal Invoices fix).
+
+**MED — Unit-price label.** Offers "Cena/ks" (`:336`, `:1625`) → "Jedn. cena". Effort: **S**.
+**MED — Unit-price + quantity header alignment/width.** Offers default-left, qty `5rem` → `align="center"`, qty `5.5rem`. Also InvoiceDetail's paid read-only header uses `align="right"` (`:1429`) — switch to `center`. Effort: **S**.
+**MED — Grand-total label.** Invoices "Celkem k úhradě:" is domain-appropriate (payment context) — **keep, intentional.**
+**MED — Editable VAT-column header.** Unify the two editable forms on "DPH"; align Invoices' paid-view header. Effort: **S**.
+**LOW — Remove-button cell width.** Offers `3rem` → `2.5rem`. Effort: **S**.
+
+_Already fine: description/detail multiline fields (rows=2, vertical resize), unit-price column width `8rem`, per-row monospace total, mobile card metrics, dnd-kit drag config, totals area layout, per-rate VAT breakdown._
+
+## 4. Suggested Fix Order
+
+**Batch 1 — Mechanical quick wins (low judgment, low risk).**
+
+1. Line-item unifications in `OfferDetail.tsx`: "Cena/ks"→"Jedn. cena", qty width `5rem`→`5.5rem`, `align="center"` on qty/unit-price headers, remove-button cell `3rem`→`2.5rem`. Plus in-Invoices fixes (paid-view unit-price `right`→`center`; "%DPH"→"DPH").
+2. List: "Částka"→"Celkem" (ReceivedInvoices); center Offers tabs.
+3. Detail: Offers save button → spinner+text; standardize status-transition button colors (Order rule); back-button tab params (Invoices→`?tab=issued`).
+4. Forms: `apply_vat` raw `<input>` → kit `CheckboxField` in Invoice/Order; Orders currency Select → company settings; Orders `issued_by` read-only+auto-filled.
+
+**Batch 2 — Small behavioral additions (per-file logic, light judgment).** 5. Add `rowSx` state tinting to the three Orders modules (+ optionally ReceivedInvoices). 6. Add OrdersReceived status-filter Select; widen IssuedOrders/OrdersReceived `sortKey` coverage. 7. Adopt `hasLoadedOnce` skeleton-suppression in Offers/Invoices/IssuedOrders/OrdersReceived. 8. Search-aware empty states (Offers pattern) in Invoices/IssuedOrders/OrdersReceived.
+
+**Batch 3 — Safety/feature bug fixes (need judgment, preserve data logic).** 9. Delete-button guards: add `!readOnly`/status checks to Offers + Invoices; add a guarded delete to IssuedOrderDetail for parity. 10. Verify create-success invalidation scope for Invoice/Order; widen only if they touch foreign domains.
+
+**Batch 4 — Shared-component & layout refactors (largest, most judgment).** 11. Replace the three customer/supplier pickers with one `Autocomplete freeSolo` (consider a shared `CustomerPicker` kit component). 12. Move Invoices notes to RichEditor + wire DOMPurify/`cleanQuillHtml` on PDF + render paths. 13. Unify VAT rate/toggle layout on Offers' dual-field pattern. 14. Add KPI StatCard grids to IssuedOrders/OrdersReceived (decide metrics; consider an Offers variant). 15. Refactor InvoiceDetail's separate paid read-only branch into the single-form-`readOnly`-prop model; hoist guards to top-level. 16. Reduce Offers row actions to 4 (move Duplicate/Invalidate to overflow menu/detail).
+
+## 5. Already Consistent — Do Not Touch
+
+- **Shell & layout:** `PageEnter`, `PageHeader`, `Card` sectioning, `FilterBar`, header layout + `headerActionsSx`, StatusChip-in-header, mobile breakpoints.
+- **Lists:** DataTable rendering, Pagination placement, StatusChip semantic colors, search-placeholder copy, draft-banner presence (by design).
+- **Forms:** `<Field>` wrapper + error display, DateField, totals footer, basic-info grid, delivery/payment terms being Orders-only.
+- **Line items:** description/detail multiline (rows=2, vertical resize), unit-price width `8rem`, per-row monospace total, mobile card metrics, dnd-kit drag, totals layout, per-rate VAT breakdown.
+- **Cross-cutting:** success/error handling, `formatCurrency`, permission guards.
+
+**Intentional differences to preserve:** Invoices' "Celkem k úhradě:" grand-total wording (payment context) and the supplier-vs-customer ("Dodavatel"/"Zákazník") terminology.

+
+# Part 2 — Status/State Models + Draft Persistence (follow-up audit)
+
+> Generated 2026-06-09 by a second multi-agent audit (status models + draft persistence).
+
+## Summary
+
+The five document types share the same conceptual lifecycle (draft → active → terminal/paid) but agree on almost nothing in implementation. State is stored two ways (raw `String(30)` vs Prisma enum), keyed in two languages (Czech for customer-orders, English for everything else), enforced with three transition styles, and rendered through **six separately-maintained label/color maps that have already drifted** (the same `issued` status is amber in the list, blue in the detail). Draft persistence works end-to-end only for Offers, is **half-wired for Issued Invoices (a banner promises a draft that is never written)**, and is absent everywhere else. The theme is **copy-paste divergence with no shared source of truth**.
+
+## State-model comparison

+| Document                             | Storage                    | Key language                                                 | #States | Transitions                      | Auto-transitions                         | Edit-lock                              | Color consistency                                      |
+| ------------------------------------ | -------------------------- | ------------------------------------------------------------ | ------- | -------------------------------- | ---------------------------------------- | -------------------------------------- | ------------------------------------------------------ |
+| Offer (quotations)                   | `String(30)` def `active`  | mixed (`active`/`ordered`/`invalidated`)                     | 3       | none (manual; `invalidateOffer`) | none                                     | locked only when `invalidated`         | **no label/color map** (tabs only)                     |
+| Customer Order (orders)              | `String(30)` def `prijata` | **Czech** (`prijata`/`v_realizaci`/`dokoncena`/`stornovana`) | 4       | `VALID_TRANSITIONS`              | → project status sync                    | items lock in `dokoncena`/`stornovana` | consistent list↔detail                                 |
+| Issued Order (issued_orders)         | **enum** def `draft`       | English (`draft`/`sent`/`confirmed`/`completed`/`cancelled`) | 5       | `VALID_TRANSITIONS`              | none                                     | full lock outside `draft`/`sent`       | consistent                                             |
+| Issued Invoice (invoices)            | `String(30)` def `issued`  | English (`issued`/`overdue`/`paid`)                          | 3       | `VALID_TRANSITIONS`              | `markOverdueInvoices()` + auto paid_date | full lock in `paid`                    | **DRIFTED**: `issued`=warning in list, =info in detail |
+| Received Invoice (received_invoices) | **enum** def `unpaid`      | English (`unpaid`/`paid`)                                    | 2       | implicit (no revert)             | auto paid_date, month/year               | locks in `paid`                        | consistent (list only)                                 |
+
+## Intentional (KEEP) vs Accidental (FIX)
+
+**Domain-justified — keep:** different state counts per document (orders need 5, received invoices need 2); Offers' transition-free lifecycle (document it); the customer-order→project sync and invoice auto-overdue business rules; stricter edit-lock on terminal states.
+
+**Accidental — fix:**
+
+- Czech vs English status keys (customer-orders are the lone Czech holdout — legacy-PHP carryover).
+- String vs enum storage (orders/quotations/invoices loose `String`; issued_orders/received_invoices typed enums).
+- Divergent semantic color for the same status (`issued` = warning vs info).
+- Six duplicated, drifting `STATUS_LABELS`/`STATUS_COLORS` maps; Offers has none.
+- Duplicated draft-key constants (`boha_offer_draft` defined in two files).
+- **Half-wired issued-invoice draft** (banner reads a key that's never written; `clearDraft` is dead code) — a live user-facing bug.
+- Cross-record draft leakage (`boha_offer_draft` not record-scoped).
+- Auto-transition logic placed in three different homes (service vs scheduled fn vs route handler).
+- Arbitrary draft-banner visibility heuristics.
+
+## Recommendations
+
+- **Status keys → English** (4/5 already English; matches CLAUDE.md identifier convention). Rename customer-order DB values (`prijata`→`received`, `v_realizaci`→`in_progress`, `dokoncena`→`completed`, `stornovana`→`cancelled`) + the `ORDER_TO_PROJECT_STATUS` keys. **Needs DB migration + backfill.**
+- **Storage → Prisma enums** for invoices/orders/quotations (match the other two). **Migration**, mechanical; do in the same migration as the rename.
+- **One shared `src/admin/lib/documentStatus.ts`** exporting per-document `STATUS_LABELS` + `STATUS_COLORS` (Czech labels, MUI colors), consumed everywhere — kills all six duplicates, fixes the `issued` color drift in one place (→ `warning`), gives Offers a chip. Fold draft-key constants into a shared `DRAFT_KEYS`. **Frontend-only.**
+- **Drafts → uniform or removed; never half-wired.** Recommended: a reusable `useDocumentDraft(key, { recordId })` hook (record-scoped, debounced autosave, restore-on-init, unified banner) applied to all create/edit forms; finish the stubbed invoice banner. Acceptable cheaper alternative: delete drafts entirely. Either way, fix the half-wired invoice banner. **Frontend-only.**
+- **Transition placement → one home** (service layer, never the route). **Backend-only, no migration.**
+
+## Effort + risk
+
+- **Frontend-only (cheap, safe, do now):** shared `documentStatus.ts` (+ fix `issued` color drift, + Offers chip), fix the half-wired invoice draft, record-scoped `useDocumentDraft` hook + leakage guard + banner unification.
+- **Backend, no migration (low risk, opportunistic):** centralize auto-transition logic into services; document Offers' transition-free lifecycle.
+- **Backend + DB migration (higher risk, deferrable, do as ONE planned tested change):** Czech→English customer-order status rename (DB values + transition map + project-sync keys + frontend maps in lockstep, with `UPDATE` backfill); String→enum conversion for invoices/orders/quotations. **Not correctness blockers** (the String columns work today) — schedule deliberately.

+# Odin Multi-Conversation Chat — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Turn the single-thread Odin assistant into a multi-conversation chat (top-tabs, rename/delete, auto-title) on the `/odin` page.
+
+**Architecture:** New `ai_conversations` table; `ai_chat_messages` gains `conversation_id` (FK, cascade). Conversation-scoped service + routes replace the single `/history` endpoints. A new `OdinChat` component (+ focused sub-components) replaces `DashAssistant`, keeping all proven chat/extract/save logic but scoped to the active conversation.
+
+**Tech Stack:** Fastify 5, Prisma 6 (MySQL), Zod 4, React 18 + MUI v7, TanStack Query, Vitest (real DB).
+
+**Spec:** `docs/superpowers/specs/2026-06-08-odin-conversations-design.md`.

+
+**Controller note (migration):** Tasks that touch the DB require the dev server stopped. After Task 1's files are written, the **controller** runs: ask user to stop dev server → `npx prisma generate` → `npx prisma migrate deploy` (applies to dev `app` DB) → resume. Backend tsc is red between Task 1 and Task 2 (data model changes before the service is updated) — that is expected; Task 2 restores green.
+
+---
+
+## Task 1: Data model + migration
+
+**Files:**
+
+- Modify: `prisma/schema.prisma`
+- Create: `prisma/migrations/20260608140000_add_ai_conversations/migration.sql`
+
+- [ ] **Step 1: Edit `prisma/schema.prisma`** — replace the existing `ai_chat_messages` model and add `ai_conversations` above it:
+
+```prisma
+model ai_conversations {
+  id         Int                @id @default(autoincrement())
+  user_id    Int
+  title      String             @db.VarChar(255)
+  created_at DateTime           @default(now()) @db.Timestamp(0)
+  updated_at DateTime           @default(now()) @updatedAt @db.Timestamp(0)
+  messages   ai_chat_messages[]
+
+  @@index([user_id, id], map: "idx_ai_conv_user")
+}
+
+model ai_chat_messages {
+  id              Int              @id @default(autoincrement())
+  user_id         Int
+  conversation_id Int
+  role            String           @db.VarChar(20)
+  content         String           @db.Text
+  created_at      DateTime         @default(now()) @db.Timestamp(0)
+  conversation    ai_conversations @relation(fields: [conversation_id], references: [id], onDelete: Cascade)
+
+  @@index([conversation_id, id], map: "idx_ai_chat_conv")
+}
+```
+
+- [ ] **Step 2: Write the migration SQL** at `prisma/migrations/20260608140000_add_ai_conversations/migration.sql`:
+
+```sql
+-- Multi-conversation Odin: conversations table + conversation_id on messages.
+
+CREATE TABLE `ai_conversations` (
+  `id` INTEGER NOT NULL AUTO_INCREMENT,
+  `user_id` INTEGER NOT NULL,
+  `title` VARCHAR(255) NOT NULL,
+  `created_at` TIMESTAMP(0) NOT NULL DEFAULT CURRENT_TIMESTAMP(0),
+  `updated_at` TIMESTAMP(0) NOT NULL DEFAULT CURRENT_TIMESTAMP(0),
+  PRIMARY KEY (`id`),
+  INDEX `idx_ai_conv_user` (`user_id`, `id`)
+) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
+
+ALTER TABLE `ai_chat_messages`
+  ADD COLUMN `conversation_id` INTEGER NULL AFTER `user_id`;
+
+-- Backfill: one conversation per user who has messages ("keep as first conversation").
+INSERT INTO `ai_conversations` (`user_id`, `title`, `created_at`, `updated_at`)
+SELECT `user_id`, 'Konverzace', NOW(), NOW()
+FROM `ai_chat_messages`
+GROUP BY `user_id`;
+
+UPDATE `ai_chat_messages` m
+JOIN `ai_conversations` c ON c.`user_id` = m.`user_id`
+SET m.`conversation_id` = c.`id`;
+
+-- Enforce: drop old per-user index, NOT NULL, FK (cascade), per-conversation index.
+ALTER TABLE `ai_chat_messages`
+  DROP INDEX `idx_ai_chat_user`,
+  MODIFY `conversation_id` INTEGER NOT NULL,
+  ADD CONSTRAINT `fk_ai_chat_conv` FOREIGN KEY (`conversation_id`)
+    REFERENCES `ai_conversations`(`id`) ON DELETE CASCADE,
+  ADD INDEX `idx_ai_chat_conv` (`conversation_id`, `id`);
+```
+
+- [ ] **Step 3: Controller applies the migration** (not the implementer):
+  - Ask user to stop the dev server (Prisma engine DLL is locked on Windows otherwise).
+  - `npx prisma generate` — expect "Generated Prisma Client".
+  - `npx prisma migrate deploy` — expect "Applying migration `20260608140000_add_ai_conversations`" → "successfully applied".
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add prisma/schema.prisma prisma/migrations/20260608140000_add_ai_conversations
+git commit -m "feat(odin): ai_conversations table + conversation_id on messages"
+```
+
+---
+
+## Task 2: Backend — conversation service, schemas, routes
+
+**Files:**
+
+- Modify: `src/services/ai.service.ts`
+- Modify: `src/schemas/ai.schema.ts`
+- Modify: `src/routes/admin/ai.ts`
+
+- [ ] **Step 1: Replace the chat-history block in `ai.service.ts`.** Delete `getChatHistory`, `appendChatMessages`, `clearChatHistory` and the `HISTORY_LIMIT` const, and put this in their place (keep the `StoredChatMessage` interface):
+
+```ts
+// ── Conversations (server-side, per user) ─────────────────────────────────

+  return { data: { ok: true } };
+}
+```
+
+- [ ] **Step 2: Schemas** — in `src/schemas/ai.schema.ts`, keep `AiHistoryAppendSchema` (reused for append) and add:
+
+```ts
+export const AiCreateConversationSchema = z.object({
+  title: z.string().max(255).optional(),
+});
+
+export const AiRenameConversationSchema = z.object({
+  title: z.string().min(1, "Název je povinný").max(255),
+});
+```
+
+- [ ] **Step 3: Routes** — in `src/routes/admin/ai.ts`: update imports (drop `getChatHistory/appendChatMessages/clearChatHistory`, add the new fns; add `AiCreateConversationSchema, AiRenameConversationSchema`; import `parseId` from `"../../schemas/common"`). Delete the three `/history` route blocks and append these (all `requirePermission("ai.use")`):
+
+```ts
+// GET /conversations — this user's conversations (stable order)
+app.get(
+  "/conversations",
+  { preHandler: requirePermission("ai.use") },
+  async (request: FastifyRequest, reply: FastifyReply) => {
+    const conversations = await listConversations(request.authData!.userId);
+    return success(reply, { conversations });
+  },

+    if ("error" in body) return error(reply, body.error, 400);
+    const conversation = await createConversation(
+      request.authData!.userId,
+      body.data.title,
+    );
+    return success(reply, { conversation });

+  { preHandler: requirePermission("ai.use") },
+  async (request: FastifyRequest, reply: FastifyReply) => {

+    );
+    if ("error" in result) return error(reply, result.error, result.status);
+    return success(reply, result.data);
+  },
+);
+
+// PATCH /conversations/:id — rename
+app.patch(
+  "/conversations/:id",
+  { preHandler: requirePermission("ai.use") },
+  async (request: FastifyRequest, reply: FastifyReply) => {

+    if (id === null) return;
+    const body = parseBody(AiRenameConversationSchema, request.body);
+    if ("error" in body) return error(reply, body.error, 400);
+    const result = await renameConversation(

+    return success(reply, result.data);
+  },

+- [ ] **Step 4: Gate**
+
+Run: `npx tsc -b --noEmit` — expect exit 0. Run: `npm run build` — expect success.

+
+## Task 3: Backend tests
+
+**Files:**
+
+- Modify: `src/__tests__/ai.test.ts`
+
+- [ ] **Step 1: Replace the imports + cleanup markers.** Swap the history-fn imports for the conversation fns, and update the top-of-file constants/cleanup:
+
+```ts
+import {
+  computeCostUsd,
+  recordUsage,
+  getMonthSpendUsd,
+  getBudgetUsd,
+  assertBudgetAvailable,
+  isConfigured,
+  listConversations,
+  createConversation,
+  getConversationMessages,
+  appendConversationMessages,
+  renameConversation,
+  deleteConversation,
+} from "../services/ai.service";
+
+const KIND = "test_ai";
+const CONV_UID_A = 999999991; // synthetic, FK-free owner ids
+const CONV_UID_B = 999999992;
+const HIST_MARKER = "「test-conv」"; // marks HTTP-test conversations on real users
+```
+
+Update the top-level cleanup (`afterAll` and the conversation `beforeEach`) to delete by these. Deleting a conversation cascades its messages:
+
+```ts
+afterAll(async () => {
+  await prisma.ai_usage.deleteMany({ where: { kind: KIND } });
+  await prisma.ai_conversations.deleteMany({
+    where: { user_id: { in: [CONV_UID_A, CONV_UID_B] } },

+
+**Files:**
+
+- Modify: `src/admin/lib/queries/ai.ts`
+
+- [ ] **Step 1: Add conversation options.** Keep everything (incl. `aiHistoryOptions` for now — it's removed in Task 6 alongside its only consumer `DashAssistant.tsx`, so every task stays green). Add:
+
+```ts
+export interface Conversation {
+  id: number;
+  title: string;
+  updated_at: string;
+}
+
+export const aiConversationsOptions = () =>
+  queryOptions({
+    queryKey: ["ai", "conversations"],
+    queryFn: () =>
+      jsonQuery<{ conversations: Conversation[] }>(
+        "/api/admin/ai/conversations",
+      ),
+    staleTime: 30_000,
+  });
+
+export const aiConversationMessagesOptions = (id: number) =>
+  queryOptions({
+    queryKey: ["ai", "conversation", id, "messages"],
+    queryFn: () =>
+      jsonQuery<{ messages: StoredChatMessage[] }>(
+        `/api/admin/ai/conversations/${id}/messages`,
+      ),
+    // Re-read the DB on each mount/selection (no stale-cache resurrection).
+    staleTime: Infinity,
+    gcTime: 0,
+  });
+```
+
+- [ ] **Step 2: Gate**
+
+Run: `npx tsc -p tsconfig.app.json --noEmit` — expect exit 0 (we kept `aiHistoryOptions`, so `DashAssistant.tsx` still compiles).
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/admin/lib/queries/ai.ts
+git commit -m "feat(odin): conversation query options"
+```
+
+---
+
+## Task 5: Frontend presentational components
+
+**Files:**
+
+- Create: `src/admin/components/odin/OdinTabs.tsx`
+- Create: `src/admin/components/odin/OdinThread.tsx`
+- Create: `src/admin/components/odin/InvoiceReviewCard.tsx`
+- Create: `src/admin/components/odin/OdinComposer.tsx`
+
+These are **props-driven** (no data fetching). Port presentational details (bubble styling, the `Typography`-color fix, review-card fields, staged chips) from the current `src/admin/components/dashboard/DashAssistant.tsx`, which the implementer should read first.
+
+- [ ] **Step 1: Shared types** — define at the top of `OdinChat.tsx` (Task 6) and import where needed, OR duplicate the tiny `ChatTurn` shape. Use these exact shapes across files:
+
+```ts
+export interface ChatTurn {
+  role: "user" | "assistant";
+  content: string;
+}
+export interface ReviewInvoice {
+  uid: string;
+  supplier_name: string;
+  invoice_number: string;
+  amount: string;
+  currency: string;
+  vat_rate: string;
+  issue_date: string;
+  due_date: string;
+  description: string;
+  file_name: string;
+  file: File;
+}
+export type EditableField =
+  | "supplier_name"
+  | "invoice_number"
+  | "amount"
+  | "currency"
+  | "vat_rate"
+  | "issue_date"
+  | "due_date"
+  | "description";
+export interface StagedFile {
+  id: string;
+  file: File;
+}
+```
+
+Put these in a new `src/admin/components/odin/types.ts` and import from there in every odin file.
+
+- [ ] **Step 2: `OdinTabs.tsx`** — props and behavior:
+
+```tsx
+interface OdinTabsProps {
+  conversations: { id: number; title: string }[];
+  activeId: number | null;
+  busy: boolean;
+  onSelect: (id: number) => void;
+  onNew: () => void;
+  onRename: (id: number, title: string) => void;
+  onDelete: (id: number) => void;
+}
+```
+
+Render a horizontally-scrollable row (`Box` with `overflowX: "auto"`, `display: flex`, `gap`). Each conversation is a clickable pill (`Button` size small; active = `contained`, else `outlined color="inherit"`). After the pills, a `+` `Button` calls `onNew`. The **active** pill shows a small `⋮` `IconButton` opening an `@mui/material` `Menu` with "Přejmenovat" and "Smazat". "Přejmenovat" opens the kit `Modal` containing a `TextField` (prefilled with current title) → on submit calls `onRename`. "Smazat" opens the kit `ConfirmDialog` → on confirm calls `onDelete`. All actions disabled while `busy`.
+
+- [ ] **Step 3: `OdinThread.tsx`** — props:
+
+```tsx
+interface OdinThreadProps {
+  turns: ChatTurn[];
+  busy: boolean;
+  loading: boolean;
+  threadRef: React.RefObject<HTMLDivElement>;
+}
+```
+
+Render the scrolling message area (`flex: 1, minHeight: 0, overflowY: "auto"`). Assistant turns left with a small circular Odin avatar (`Box` 28px, `borderRadius: "50%"`, `bgcolor: "primary.main"`, white "O"); user turns right-aligned `primary.main` bubble. **Message colour MUST be on the `Typography`** (`color: user ? "common.white" : "text.primary"`) — GlobalStyles pins `p` to text.secondary. Empty state (no turns, not busy, not loading): centered Odin avatar + "Dobrý den, jsem Odin. Zeptejte se, nebo přiložte fakturu (PDF) k importu." When `loading`: "Načítám…". When `busy`: a `CircularProgress size={14}` + "Pracuji…" row.
+
+- [ ] **Step 4: `InvoiceReviewCard.tsx`** — props:
+
+```tsx
+interface InvoiceReviewCardProps {
+  inv: ReviewInvoice;
+  busy: boolean;
+  onChange: (uid: string, field: EditableField, value: string) => void;
+  onSave: (inv: ReviewInvoice) => void;
+  onDiscard: (uid: string) => void;
+}
+```
+
+Port the card body from `DashAssistant.tsx` verbatim (the `Chip "Faktura"` + filename header, the 2-col grid of `TextField`s including **"Částka s DPH"**, "Datum splatnosti", "Popis", and the Uložit / Zahodit buttons). Replace `patch(...)`→`onChange(...)`, `saveInvoice`→`onSave`, the discard filter→`onDiscard(inv.uid)`.
+
+- [ ] **Step 5: `OdinComposer.tsx`** — props:
+
+```tsx
+interface OdinComposerProps {
+  input: string;
+  attachments: StagedFile[];
+  busy: boolean;
+  canSubmit: boolean;
+  fileRef: React.RefObject<HTMLInputElement>;
+  onInput: (v: string) => void;
+  onFiles: (files: FileList | null) => void;
+  onRemoveAttachment: (id: string) => void;
+  onSubmit: () => void;
+}
+```
+
+Port the staged-attachment chips + the composer row (hidden file `input`, "Přiložit" button, `TextField` with Enter-to-submit, "Odeslat" button) from `DashAssistant.tsx`. Disable per `busy` / `!canSubmit`.
+
+- [ ] **Step 6: Gate**
+
+Run: `npx tsc -p tsconfig.app.json --noEmit` — expect exit 0 (these compile independently of the orchestrator). If a component is unused at this point, that is fine — Task 6 wires them.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add src/admin/components/odin
+git commit -m "feat(odin): tabs, thread, review-card, composer components"
+```
+
+---
+
+## Task 6: OdinChat orchestrator + page + delete DashAssistant
+
+**Files:**
+
+- Create: `src/admin/components/odin/OdinChat.tsx`
+- Modify: `src/admin/pages/Odin.tsx`
+- Modify: `src/admin/lib/queries/ai.ts` (remove `aiHistoryOptions`)
+- Delete: `src/admin/components/dashboard/DashAssistant.tsx`
+
+- [ ] **Step 1: Write `OdinChat.tsx`.** It owns all state + queries + the ported submit/extract/save logic, scoped to the active conversation. Port the helper fns (`summaryNote`, `nextUid`, `plural`, `MODEL_CONTEXT`, `MAX_STORE`) and the **submit / saveInvoice / onFiles / persist** logic from `DashAssistant.tsx` with these adaptations:
+  - **Queries:** `usage` (unchanged), `aiConversationsOptions()`, and `aiConversationMessagesOptions(activeId)` (enabled when `activeId != null`).
+  - **State:** `activeId: number | null`, plus `input`, `busy`, `turns`, `review`, `attachments`, `fileRef`, `threadRef`.
+  - **Ensure a conversation exists:** when the conversations query resolves: if empty, `POST /conversations` to create a default and `setActiveId(new.id)` + invalidate `["ai","conversations"]`; else if `activeId == null`, `setActiveId(list[0].id)`.
+  - **Seed per conversation:** a `seededId = useRef<number|null>(null)`. Effect keyed on `[activeId, messagesData]`: when `messagesData` for the active id arrives and `seededId.current !== activeId`, set `seededId.current = activeId`, `setTurns(messagesData.messages.map(m => ({role:m.role, content:m.content})))`, `setReview([])`.
+  - **Switch tab (`onSelect`):** `setActiveId(id); setTurns([]); setReview([]); seededId.current = null;` (force re-seed; the messages query for the new id loads and seeds).
+  - **`persist(msgs)`** posts to `/api/admin/ai/conversations/${activeId}/messages` (was `/history`); best-effort + `console.error` on failure.
+  - **`submit`:** identical to `DashAssistant.submit` EXCEPT it first ensures `activeId` (if null, await-create one and use it); marks `seededId.current = activeId`; on success persists via the conversation endpoint; on error rolls back + keeps input/attachments. Gate `canSubmit` on `!conversationsPending && activeId != null && !busy && (input.trim() || attachments.length)`.
+  - **`onNew`:** `POST /conversations` → select it (`setActiveId`, clear turns/review, `seededId.current=null`) + invalidate `["ai","conversations"]`.
+  - **`onRename(id, title)`:** `PATCH /conversations/:id` → invalidate `["ai","conversations"]`.
+  - **`onDelete(id)`:** `DELETE /conversations/:id` → invalidate `["ai","conversations"]`; if `id === activeId`, pick another conversation from the (refetched) list or null.
+  - **Layout:** a full-height shell — `Box sx={{ height: "calc(100dvh - 140px)", display: "flex", flexDirection: "column" }}` containing: header (`Odin` + budget `Utraceno: $x / $y`), `<OdinTabs … />`, `<OdinThread … />` (flex 1), the review list (`review.map(inv => <InvoiceReviewCard … />)` in a bounded `maxHeight: "35vh", overflowY: "auto"` box), and `<OdinComposer … />`.
+  - **Self-hide:** keep `if (usage && usage.configured === false) return null;`.
+
+Reference the exact bodies of `submit`, `saveInvoice`, `onFiles`, `summaryNote`, `nextUid` in the current `DashAssistant.tsx` (lines ~52–333) — copy them, applying only the adaptations above.
+
+- [ ] **Step 2: Update `src/admin/pages/Odin.tsx`** — swap the import and render:
+
+```tsx
+import OdinChat from "../components/odin/OdinChat";
+// …
+<Box sx={{ maxWidth: 1100, mx: "auto" }}>
+  <OdinChat />
+</Box>;
+```
+
+- [ ] **Step 3: Delete `src/admin/components/dashboard/DashAssistant.tsx`** and remove the now-orphaned `aiHistoryOptions` from `src/admin/lib/queries/ai.ts` (DashAssistant was its only consumer).
+
+```bash
+git rm src/admin/components/dashboard/DashAssistant.tsx
+```
+
+- [ ] **Step 4: Gate**
+
+Run: `npx tsc -b --noEmit` — expect exit 0. Run: `npm run build` — expect success. Run: `npx vitest run` — expect the full suite green.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/admin/components/odin/OdinChat.tsx src/admin/pages/Odin.tsx src/admin/lib/queries/ai.ts
+git commit -m "feat(odin): OdinChat orchestrator; render on /odin; remove DashAssistant"
+```
+
+---
+
+## Final verification (controller)
+
+- `npx tsc -b --noEmit` = 0, `npm run build` = success, `npx vitest run` = all green.
+- Manual (user/controller): create a conversation, send a chat, attach a PDF → review → save, rename a tab, delete a tab, reload (history persists per conversation), switch tabs (each keeps its own thread).
+- Adversarial review pass (workflow) before merge/release.

+# 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

+      (buildTripsWhere shared), vehicle_id on PUT + both-vehicle odometer recompute,

+# Design — AI assistant, Phase 1 (chat + invoice import + budget cap)
+
+**Date:** 2026-06-08
+**Status:** Approved (brainstorming) — ready for implementation plan
+**Phase 1 of 2.** Phase 2 (the AI querying system data via read-tools) is a separate later cycle — see "Deferred: Phase 2" at the end.
+
+---
+
+## Goal
+
+Add the app's first AI capability: an **admin-only chat assistant embedded on the
+dashboard** where you can talk to Claude and, crucially, **attach received-invoice
+PDFs that the AI reads and imports into Přijaté faktury** (extract → you confirm →
+save). All AI usage is bounded by an **admin-editable monthly budget (default
+$50)** that hard-stops calls when exhausted.
+
+## Decisions (locked in brainstorming)
+
+- **Scope (Phase 1):** chat + invoice import + budget cap. **No system-data
+  access** (the AI cannot query your invoices/projects/attendance — that's Phase 2).
+- **Placement:** a `DashAssistant` widget on the **dashboard, at the top under the
+  welcome text** — not a separate page, not a floating bubble.
+- **Access:** **admins only**, via a new `ai.use` permission.
+- **Model:** **Claude Sonnet 4.6** (strong vision, low cost).
+- **Save flow:** extract → **you confirm/edit → save** (never silent auto-save).
+- **Budget:** **$50/month**, resets each calendar month, **admin-editable in
+  Settings**; AI calls are **blocked** once the month's spend reaches the budget.
+- **Chat:** **non-streaming** (request → full reply) and **in-browser history
+  only** (not persisted server-side) for v1 — both are easy later upgrades.
+
+## Non-goals / out of scope (Phase 1)
+
+- No system-data query tools / function-calling (Phase 2).
+- No server-side conversation persistence, no streaming.
+- No new invoice storage path — reuses `POST /received-invoices` verbatim.
+
+---
+
+## Architecture
+
+Greenfield AI integration; the rest of the app is unaffected and works unchanged
+if `ANTHROPIC_API_KEY` is absent (the assistant widget simply doesn't render and
+the AI routes return a clear "not configured" error).
+
+- **Dependency:** `@anthropic-ai/sdk`.
+- **Env:** `ANTHROPIC_API_KEY` (required for the feature). Optional
+  `AI_MONTHLY_BUDGET_USD` default seed (the live value lives in the DB, below).
+- **`src/services/ai.service.ts`** — wraps the SDK, owns the model choice + system
+  prompt + cost accounting. Two operations:
+  - `chat(messages)` → `client.messages.create({ model: "claude-sonnet-4-6", … })`,
+    non-streaming, returns `{ reply: string, usage }`.
+  - `extractInvoice(pdfBuffer, fileName)` → `client.messages.create` with the PDF as
+    a `document` content block + `output_config.format` JSON-schema for the
+    received-invoice fields, returns `{ fields, usage }`.
+  - Both call the spend tracker to record usage **and** are gated by the budget
+    guard (below) BEFORE the API call.
+  - Isolated so tests can stub the Anthropic call (no real API in CI).
+
+## Spend cap (the $50/month budget)
+
+- **New table `ai_usage`** (migration): `id`, `user_id?`, `kind` ("chat" |
+  "extract"), `model`, `input_tokens`, `output_tokens`, `cost_usd`
+  `@db.Decimal(10,6)`, `created_at @db.Timestamp(0)`, with an index on
+  `created_at`.
+- **Cost map** (in `ai.service.ts`): model → `{ inputPerToken, outputPerToken }`.
+  Sonnet 4.6 = $3 / $15 per 1M → `0.000003` / `0.000015` per token. `cost_usd =
+in*inP + out*outP`.
+- **Budget value:** a new `ai_monthly_budget_usd Decimal @default(50)` column on
+  `company_settings` (the existing app-config singleton). Admin-editable in
+  Settings.
+- **Budget guard `assertBudgetAvailable()`:** sum `cost_usd` for rows where
+  `created_at >= startOfMonth(now)`; if `>= ai_monthly_budget_usd`, return
+  `{ error: "Měsíční rozpočet AI byl vyčerpán", status: 402 }`. Called at the top
+  of every AI route BEFORE the Claude call.
+- **Usage read:** `GET /api/admin/ai/usage` → `{ month_spend_usd, budget_usd,
+remaining_usd }` for the chat's budget indicator and the Settings page.
+
+## Backend routes — `src/routes/admin/ai.ts`
+
+All guarded by `requirePermission("ai.use")`.
+
+- `POST /api/admin/ai/chat` — body `{ messages: {role, content}[] }`. Budget guard →
+  `ai.service.chat` → log usage → `success(reply: string, remaining_usd)`.
+- `POST /api/admin/ai/extract-invoices` — multipart PDF files (≤ `MAX_UPLOAD_SIZE`,
+  PDF/image only). Budget guard → `extractInvoice` per file → returns the extracted
+  fields per file (NOT saved) + usage. The files are **not** persisted here.
+- `GET /api/admin/ai/usage` — current-month spend + budget + remaining.
+
+If `ANTHROPIC_API_KEY` is unset, the POST routes return
+`{ error: "AI není nakonfigurováno", status: 503 }`.
+
+## Invoice import flow (extract → confirm → save)
+
+1. Admin attaches one or more invoice PDFs in the dashboard chat (optionally with a
+   text note).
+2. Frontend posts the files to `POST /ai/extract-invoices`; the AI returns the
+   extracted fields for each.
+3. The chat renders an **editable review card per invoice** (dodavatel, číslo
+   faktury, částka, měna, sazba DPH, datum vystavení/splatnosti, poznámka),
+   pre-filled with the AI's values, plus a duplicate hint if `invoice_number` +
+   `supplier_name` already exists.
+4. Admin glances/edits → **"Uložit"** (per card) or **"Uložit vše"**.
+5. The frontend submits **the original File + the confirmed metadata** to the
+   **existing `POST /api/admin/received-invoices`** (multipart) — same NAS storage,
+   same server-side VAT recompute, same audit. The AI never writes invoices
+   directly. (The PDF is uploaded twice — once to extract, once to save — which is
+   fine for invoice-sized files and avoids any server-side temp-file handling.)
+
+## Frontend
+
+- **`src/admin/components/dashboard/DashAssistant.tsx`** — the chat widget:
+  message list, input box, attach-file button, and a small budget indicator
+  ("Rozpočet: $X.XX / $50"). Non-streaming; conversation in component state only.
+  Renders the invoice review cards inline (reusing the received-invoice field
+  inputs / kit components).
+- **`src/admin/pages/Dashboard.tsx`** — render `<DashAssistant />` at the top,
+  directly under the welcome text, **only when** the user is admin / has `ai.use`
+  (and only when AI is configured — a `GET /ai/usage` 503 hides it gracefully).
+- **`src/admin/lib/queries/ai.ts`** — React Query options/mutations for chat,
+  extract, and usage. On a successful invoice save, invalidate `["received-invoices"]`.
+- **Settings** — an admin field to set the monthly budget (writes
+  `company_settings.ai_monthly_budget_usd`).
+
+## Permissions & migration
+
+One Prisma migration:
+
+- Create `ai_usage` table.
+- Add `ai_monthly_budget_usd` to `company_settings` (default 50).
+- Insert the `ai.use` permission and grant it to the **admin** role (explicit
+  `INSERT`s in `migration.sql`, per the project's migration policy).
+
+(The admin role bypasses permission checks via `roleName === "admin"`, but the
+explicit `ai.use` permission lets the access be widened later without code changes
+and documents intent.)
+
+## Security / privacy
+
+- **Phase 1 has no tools**, so the AI cannot take actions on your data — its only
+  effect is the human-confirmed invoice save. A malicious/auto-generated invoice
+  PDF therefore can't trigger anything (the injection-to-action surface arrives in
+  Phase 2 and is designed there).
+- Attached PDFs are sent to the Anthropic API to be read. The API key lives in
+  `.env` (server-side only), never exposed to the browser.
+- Standard sanitization already applies on the received-invoice render/PDF paths;
+  AI-extracted text flows through the same validated `received_invoices` create.
+
+## Testing
+
+Server-side, real test DB, **Anthropic call stubbed** (no real API in CI):
+
+- **Spend tracker:** `cost_usd` computed correctly from tokens for Sonnet 4.6;
+  monthly sum only counts the current month.
+- **Budget guard:** under budget → allowed; at/over budget → `402` with the Czech
+  message; the guard reads the DB budget value.
+- **Permissions:** all `/ai/*` routes return `403` without `ai.use`.
+- **Not-configured:** with no `ANTHROPIC_API_KEY`, POST routes return `503`.
+- **extract field-mapping:** given a stubbed AI response, the route returns the
+  expected `received_invoices` field shape (and computes nothing that the existing
+  create doesn't already).
+
+Frontend has no component-test harness → gated by `tsc -b` + `build` + a manual
+check (the dashboard widget renders for admins, hidden otherwise).
+
+Gates: `npx tsc -b --noEmit`, `npm run build`, `npx vitest run`.
+
+## Rollout
+
+Ships as **v2.1.0** (notable new capability) via the standard process. **Requires a
+migration**, so the dev server must be stopped for `prisma migrate dev` (ask first),
+and the release runs `prisma migrate deploy` on prod. `ANTHROPIC_API_KEY` must be
+set in the production `.env` before the feature works.
+
+---
+
+## Deferred: Phase 2 (system-data access) — captured
+
+A later, separate spec + cycle. The AI gains **read-only tools** (function calling)
+to answer questions about your data — e.g. "co je po splatnosti?", "kolik jsme
+fakturovali v květnu?". Key design work for Phase 2:
+
+- A curated set of **read tools** (search invoices, overdue list, project lookup,
+  attendance summary, …), each **scoped to the calling user's permissions** so the
+  AI never returns data the user can't see.
+- The **agentic tool-loop** (Claude requests a tool → app executes against Prisma →
+  returns results → Claude continues), with a per-conversation tool-call cap to
+  bound cost (within the same monthly budget).
+- **Prompt-injection hardening:** because the AI will both read untrusted invoice
+  content _and_ hold tools, tools stay **read-only**, results are treated as data,
+  and any state-changing action remains human-confirmed.

+# Odin — Multi-Conversation AI Chat — Design
+
+**Date:** 2026-06-08
+**Status:** Approved (design), pending spec review
+
+## Goal
+
+Replace the single-thread Odin assistant with a multi-conversation chat: a
+purpose-built UI on the `/odin` page where the user keeps several named
+conversations (like topics), switches between them via top tabs, and can
+rename or delete them. All existing assistant capabilities (chat, PDF invoice
+extraction → review → save, monthly budget) carry over unchanged.
+
+## Background (current state)
+
+- `ai_chat_messages` is a single rolling thread per user (`user_id, role,
+content, created_at`). Endpoints `GET/POST/DELETE /api/admin/ai/history`
+  read/append/clear that one thread.
+- The chat lives in `DashAssistant.tsx`, rendered on the `/odin` page (moved
+  off the dashboard in the prior change, branch `feat/odin-page`).
+- Stateless AI endpoints (`/chat`, `/extract-invoices`, `/usage`, `/budget`)
+  are unaffected by conversations — they don't persist anything themselves.
+
+## Decisions (from brainstorming)
+
+- **Titling:** new conversation auto-titles from its first user message; user
+  can rename.
+- **Per-conversation actions:** rename + delete.
+- **Existing history:** migrate the current single thread into one conversation
+  per user ("keep as first conversation"); nothing is lost.
+- **Layout:** top tabs + chat (not a left sidebar).
+
+## Data model
+
+### `ai_conversations` (new)
+
+| column     | type                  | notes                               |
+| ---------- | --------------------- | ----------------------------------- |
+| id         | INT PK AUTO_INCREMENT |                                     |
+| user_id    | INT NOT NULL          | owner; isolation key                |
+| title      | VARCHAR(255) NOT NULL | default "Nová konverzace"           |
+| created_at | TIMESTAMP(0) NOT NULL | default CURRENT_TIMESTAMP           |
+| updated_at | TIMESTAMP(0) NOT NULL | bumped on each append; sort/recency |
+
+Index: `idx_ai_conv_user (user_id, id)`.
+
+### `ai_chat_messages` (modified)
+
+- Add `conversation_id INT NOT NULL` (FK → `ai_conversations(id)` `ON DELETE
+CASCADE`). Keep `user_id` (denormalized, harmless; simplifies cleanup).
+- Replace index `idx_ai_chat_user (user_id, id)` with
+  `idx_ai_chat_conv (conversation_id, id)` (messages are read per conversation).
+
+### Prisma
+
+```prisma
+model ai_conversations {
+  id         Int      @id @default(autoincrement())
+  user_id    Int
+  title      String   @db.VarChar(255)
+  created_at DateTime @default(now()) @db.Timestamp(0)
+  updated_at DateTime @default(now()) @updatedAt @db.Timestamp(0)
+  messages   ai_chat_messages[]
+
+  @@index([user_id, id], map: "idx_ai_conv_user")
+}

+  id              Int              @id @default(autoincrement())
+  user_id         Int
+  conversation_id Int
+  role            String           @db.VarChar(20)

+  created_at      DateTime         @default(now()) @db.Timestamp(0)
+  conversation    ai_conversations @relation(fields: [conversation_id], references: [id], onDelete: Cascade)
+
+  @@index([conversation_id, id], map: "idx_ai_chat_conv")
+}
+```
+
+### Migration (hand-written SQL; one tracked migration)
+
+1. `CREATE TABLE ai_conversations (...)`.
+2. `ALTER TABLE ai_chat_messages ADD COLUMN conversation_id INT NULL AFTER user_id`.
+3. Backfill one conversation per user who has messages:
+   `INSERT INTO ai_conversations (user_id, title, created_at, updated_at)
+ SELECT user_id, 'Konverzace', NOW(), NOW() FROM ai_chat_messages GROUP BY user_id;`
+4. Point messages at it:
+   `UPDATE ai_chat_messages m JOIN ai_conversations c ON c.user_id = m.user_id
+ SET m.conversation_id = c.id;`
+5. Drop the old index, enforce NOT NULL, add the FK + new index:
+   `ALTER TABLE ai_chat_messages DROP INDEX idx_ai_chat_user,
+ MODIFY conversation_id INT NOT NULL,
+ ADD CONSTRAINT fk_ai_chat_conv FOREIGN KEY (conversation_id)
+   REFERENCES ai_conversations(id) ON DELETE CASCADE,
+ ADD INDEX idx_ai_chat_conv (conversation_id, id);`
+
+The backfill is a no-op when `ai_chat_messages` is empty (prod today), and
+preserves the dev thread.
+
+## Service layer (`ai.service.ts`)
+
+Replace the single-thread helpers (`getChatHistory` / `appendChatMessages` /
+`clearChatHistory`) with conversation-scoped ones. Every function takes
+`userId` and verifies the conversation belongs to the user.
+
+- `listConversations(userId)` → `{id, title, updated_at}[]`, ordered by `id` asc
+  (stable tab order).
+- `createConversation(userId, title?)` → the new conversation (default title
+  "Nová konverzace").
+- `getConversation(userId, id)` → conversation or null (ownership check helper).
+- `getConversationMessages(userId, id)` → `StoredChatMessage[]` oldest→newest,
+  or `{ error, status }` if not owned/found.
+- `appendConversationMessages(userId, id, msgs)` → append; **bump `updated_at`**;
+  **auto-title**: if the conversation's title is still the default and this batch
+  has a user message, set `title` = first ~60 chars of that user message.
+- `renameConversation(userId, id, title)` / `deleteConversation(userId, id)` —
+  ownership-checked; delete cascades messages.
+
+Auto-title keeps titling server-side and robust (no client title logic).
+
+## Routes (`routes/admin/ai.ts`, all `requirePermission("ai.use")`)
+
+| Method | Path                          | Body / result                              |
+| ------ | ----------------------------- | ------------------------------------------ |
+| GET    | `/conversations`              | → `{ conversations: [...] }`               |
+| POST   | `/conversations`              | `{ title? }` → `{ conversation }`          |
+| GET    | `/conversations/:id/messages` | → `{ messages: [...] }` (404 if not owned) |
+| POST   | `/conversations/:id/messages` | `{ messages:[{role,content}] }` (1..20)    |
+| PATCH  | `/conversations/:id`          | `{ title }` (1..255)                       |
+| DELETE | `/conversations/:id`          | → `{ ok: true }`                           |
+
+`:id` parsed via `parseId`; bodies via `parseBody`; ownership 404 from the
+service surfaced with `error(reply, ...)`. The old `/history` routes are removed.
+`/chat`, `/extract-invoices`, `/usage`, `/budget` are unchanged.
+
+## Frontend
+
+### Queries (`lib/queries/ai.ts`)
+
+- `aiConversationsOptions()` → `["ai","conversations"]`, `GET /conversations`.
+- `aiConversationMessagesOptions(id)` → `["ai","conversation",id,"messages"]`,
+  `GET /conversations/:id/messages`, `gcTime: 0` (each mount re-reads the DB,
+  same rationale as today: no stale-cache resurrection).
+- Types: `Conversation { id, title, updated_at }`, reuse `StoredChatMessage`.
+
+### Components (`src/admin/components/odin/`)
+
+- **`OdinChat.tsx`** — orchestrator. Owns: active conversation id, input, busy,
+  staged attachments, review list. Loads the conversation list; ensures one
+  exists (creates a default if the user has none); loads the active thread;
+  routes send/extract/save through the active conversation. Full-height flex
+  layout: header → tabs → thread (flex-grow, scroll) → review → composer.
+- **`OdinTabs.tsx`** — horizontally-scrollable tabs (one per conversation) +
+  a "+" new-chat button + a ⋮ menu on the active tab (Přejmenovat / Smazat).
+  Rename uses a small Modal with a text field; delete uses ConfirmDialog.
+- **`OdinThread.tsx`** — message list with an Odin avatar on assistant turns,
+  user turns right-aligned; the "Pracuji…" indicator; empty-state greeting.
+  (Message text colour set on the `Typography` — GlobalStyles pins `p` to
+  text.secondary.)
+- **`InvoiceReviewCard.tsx`** — the editable extract card (supplier, number,
+  Částka s DPH, měna, sazba, dates, popis) + Uložit / Zahodit.
+- **`OdinComposer.tsx`** — staged-attachment chips + attach button + message
+  field (Enter to send) + send button; disabled until the active thread loads.
+
+`DashAssistant.tsx` is deleted; `pages/Odin.tsx` renders `OdinChat`.
+
+### Data flow
+
+1. Mount → load `aiConversationsOptions`. If empty, `POST /conversations` to
+   create a default and select it; else select the first (or last-active).
+2. Selecting a tab sets the active id → `aiConversationMessagesOptions(id)`
+   loads that thread into the displayed turns (seed-once per id; submit marks
+   the thread live so a late load can't clobber — same guard as today).
+3. **Send (chat):** optimistic user turn → `POST /chat` → append assistant
+   reply → `POST /conversations/:id/messages` persists both → bump usage. On
+   error: roll back, keep input.
+4. **Send (attachments):** `POST /extract-invoices` → review cards →
+   client-side summary turn → persist the user+summary turns. Save a card →
+   `POST /received-invoices` (gross/VAT-inclusive, unchanged).
+5. **New / rename / delete** → mutations that invalidate `["ai","conversations"]`
+   (and reset the active id appropriately on delete).
+
+### Reuse
+
+All proven logic carries over verbatim: staged-attach (no auto-send), the three
+bug fixes (no clear-on-error, rollback dangling turn, stable ids — `nextUid`,
+NOT `crypto.randomUUID`), the model-context trimming (last 20, leading-user),
+budget indicator, gross/VAT save. The only structural change is "one thread" →
+"active conversation thread", plus the tab/CRUD shell.
+
+## Error handling
+
+- Ownership: service returns `{ error: "Konverzace nenalezena", status: 404 }`
+  for a conversation the user doesn't own; routes surface it. No cross-user read
+  or write is possible (every query filters by `user_id`).
+- Persistence is best-effort and logged (never swallowed), as today.
+- Auto-create-default and create/rename/delete failures surface a Czech toast.
+
+## Testing
+
+Backend (Vitest, real DB):
+
+- Conversation CRUD: create → list → rename → delete (cascade removes messages).
+- **Isolation:** user A cannot read/append/rename/delete user B's conversation
+  (404), and `listConversations(A)` excludes B's.
+- Append: ordering oldest→newest; `updated_at` bumps; **auto-title** sets the
+  title from the first user message and does not overwrite a renamed title.
+- HTTP: routes 403 without `ai.use`; 404 for a foreign/:id; 400 on bad body.
+
+Frontend: no component tests (consistent with the codebase); gated by
+`tsc -b` + `npm run build`. Live verification by the user/controller.
+
+## Out of scope (Phase 2+)
+
+- Querying system data inside chat (the original deferred Phase-2 scope).
+- Conversation search, pinning, folders, sharing.
+- Streaming responses.

+# Odin → General Assistant (Phase 2+) — Forward-Looking Notes
+
+**Date:** 2026-06-08 · **Status:** NOT scheduled — design notes only, recorded so Phase 1 choices don't box us in.
+
+The vision: Odin grows from "chat + invoice import" into a **general assistant** that can **query system data** (invoices, projects, attendance, vehicles…) and **take actions** (create an order, mark paid, draft a quote…). This note assesses whether the Phase-1 architecture supports that, and what to carry forward deliberately.
+
+## Bottom line
+
+Phase 1 sets us up well; it does **not** box us in. Two things to carry forward on purpose:
+
+1. **Structured message storage** (content blocks, not a plain string) — cheap to plan now, costly to retrofit later.
+2. **The assistant acts strictly as the authenticated user** — every tool runs through the existing permission/ownership layer.
+
+Everything else (conversations, budget/usage, thin services) is already pointing the right way.
+
+## What Phase 1 already gets right
+
+- **Conversations** — multi-turn, persisted, per-user, isolated. Exactly the context substrate an agent needs.
+- **Budget + usage tracking + `ai.use` gate** — the cost/access spine. Tool loops spend more, so this matters _more_, not less.
+- **Thin service layer** (`{ data } | { error, status }`, ownership-checked) — ideal to wrap as tools without rewriting business logic.
+- **The extract → review → save flow** — a perfect template for "propose action → human confirms → execute." The `canSave`/`invoices.create` gate added in Phase 1 is the one-tool version of per-action authorization.
+
+## The one schema thing to note now
+
+`ai_chat_messages.content` is a **plain string**. Tool use requires persisting **content blocks** (`text` + `tool_use` + `tool_result`), because the model must see the full tool-call history to continue. When Phase 2 lands, store the **raw content-block array** (JSON column, e.g. `content_json`/`blocks`) and keep a derived plain-text for display/search. Don't change it now — just design Phase 2 persistence as "store the blocks," treating the current string as a lossy projection.
+
+## The core shift (Phase 2)
+
+1. **Tool use over the existing services.** Define tools (`list_invoices`, `get_project`, `create_order`, …) whose handlers call the **same service functions the routes use**. The SDK tool-runner loops; we execute. Reuses all validation/business logic and — critically — permissions.
+2. **Authorization is the hard part.** Every tool MUST run **as the user**, through `requirePermission` / service ownership checks. The assistant must never do what the user can't. It is the user's _delegate_, not a privileged actor.
+3. **Read vs write.** Read/query tools may run autonomously. Write/destructive tools **propose → confirm → execute** (generalize the invoice review card into a generic "action card"). Aligns with the assistant safety rules (confirm side-effecting actions).
+4. **Audit.** Every action the assistant takes should `logAudit` like a manual action, attributed to the user with a marker (e.g. `via: "odin"`), for a real trail.
+5. **Cost.** Tool loops are multi-round-trip → 3–10× the tokens of a chat turn. The $50 cap bites faster; consider per-conversation cost display and per-action budget re-checks (the inter-file budget re-check in `extract-invoices` is the pattern).
+
+## Data access: tools-over-services, NOT RAG
+
+Recommendation: **function-calling against the real services**, not embeddings/RAG. The data is structured, live, and permissioned — tools give correct, current, authorized answers. RAG over a snapshot would be stale, would leak across permission boundaries, and would duplicate logic. Reserve embeddings for genuinely unstructured document search if it ever comes up.
+
+## Other forward notes
+
+- **Model / effort:** a true agentic assistant wants a stronger model and possibly `effort` tuning; Phase-1 Sonnet single-shot is right for now.
+- **Streaming:** multi-step tool use feels slow without it — add SSE when Phase 2 lands.
+- **System prompt:** describe the user's role + available tools + the confirm-before-write rule.
+- **Managed Agents vs self-hosted loop:** Anthropic's Managed Agents host the loop, but for a self-hosted business app with our own services + permissions, **Claude API + tool use with a self-hosted loop** is the better fit — authorization stays in our stack.
+
+## What NOT to do prematurely
+
+- Don't add a tool framework, embeddings, or streaming now — Phase 1 is plain chat + a fixed-prompt extractor, and that's the right scope.
+- Don't widen `ai.use` to non-admins until the per-action authorization story (point 2) is in place.

+# Objednávky vydané (Issued Purchase Orders) — Design Spec
+
+**Date:** 2026-06-09
+**Status:** Approved (brainstorm) → ready for implementation plan
+**Author:** brainstorm session
+
+> **Updated 2026-06-09 (as-built):** Shipped with three deviations from this
+> brainstorm — **Vydané-first tabs** (Vydané | Přijaté, mirroring Invoices), a
+> **shared chevron month/year filter** above the tabs that filters both lists,
+> and a PDF **rebuilt on the shared invoice/order-confirmation template** rather
+> than the custom layout sketched below. See the affected sections (UI placement,
+> PDF export, Frontend) and the plan's "Post-plan consistency pass" note.
+
+---
+
+## Goal
+
+Add a new document type — **objednávky vydané** (purchase orders you issue to a
+supplier) — alongside the existing customer orders. You author the PO with line
+items, it gets an auto-generated number, you track its status, and you export it
+to PDF to send to the supplier. The existing orders module becomes the
+**přijaté** (customer-order) side of a two-tab UI, mirroring how the Invoices
+page already splits **Vydané | Přijaté**.
+
+## Non-goals (v1)

+- **No cross-module wiring.** A PO does **not** link to warehouse goods receipts
+  (`sklad_receipts`) or to received invoices (`faktury přijaté`). The full
+  procurement loop (ordered → received → invoiced) is a deliberate later phase.
+- **No new supplier master.** POs reuse the existing `customers` table as generic
+  business partners.
+- **No NAS persistence of the PO PDF** in v1 (generated on demand only).
+- **No "scope sections"** (the CZ/EN rich-text blocks orders/quotations carry).
+- **No AI/Odin authoring.** POs are authored by hand; Odin extraction is a
+  received-document concept and does not apply to documents you create.
+
+---
+
+## Decisions log (resolved during brainstorm)
+
+1. **Direction mapping.** Today's `orders` (status default `prijata`, flowing
+   quotation → order → project → invoice) stay as the **Přijaté** side, largely
+   unchanged — only surfaced under a new tab. The new **Vydané** side is a
+   brand-new document type. _(Not a `direction` flag on the existing table.)_
+2. **Supplier source.** A PO references the existing **`customers`** table (FK),
+   used as a generic business partner. No new supplier/vendor master.
+3. **Linkage.** **Standalone document** in v1. No automatic links to warehouse or
+   received invoices.
+4. **UI placement.** **Tabs on the Orders page**, mirroring the Invoices page.
+   _(As-built: **Vydané first / Přijaté second** — `Vydané | Přijaté`, tab values
+   `vydane`/`prijate`, persisted in `?tab=` — matching the Invoices page order. A
+   shared **chevron month/year selector** sits above the tabs and filters BOTH
+   lists: Vydané by `order_date`, Přijaté by `created_at`. The pre-existing Přijaté
+   search bug — search term sent but ignored by the backend — was also fixed.)_
+5. **Model shape.** A **dedicated `issued_orders` + `issued_order_items`** pair,
+   mirroring `invoices`/`invoice_items` — _not_ an extension of `orders` and _not_
+   an upload-only record like `received_invoices`.
+6. **VAT regime.** **NET base + VAT-on-top** (the _issued-invoice_ convention),
+   the **opposite** of `received_invoices` (which are gross/VAT-inclusive). Totals
+   use the same per-line-rounded math as `computeInvoiceTotals`.
+7. **Numbering.** A **dedicated** `number_sequences` type (`"issued_order"`),
+   separate from the `"shared"` orders/projects pool and from `"invoice"`. Number
+   assigned **at creation** (even for a `draft`), with release-on-delete.
+8. **Permissions.** **Reuse the existing `orders.*` set** (`view`/`create`/`edit`/
+   `delete`) plus `orders.export` for the PDF — mirrors invoices sharing one
+   permission set across both tabs; **no permission migration needed**.
+
+---
+
+## Architecture
+
+A self-contained vertical slice following the codebase's established document
+pattern (the same shape `invoices` uses):
+
+```
+prisma/schema.prisma         → models issued_orders, issued_order_items + enum
+src/schemas/issued-orders.schema.ts
+src/services/issued-orders.service.ts
+src/services/numbering.service.ts        (extend: issued-order number fns)
+src/routes/admin/issued-orders.ts        (register in routes/admin/index.ts)
+src/routes/admin/issued-orders-pdf.ts    (PDF route, modeled on invoices-pdf.ts)
+src/admin/pages/Orders.tsx               (add Přijaté | Vydané tabs)
+src/admin/pages/IssuedOrderDetail.tsx    (create/edit form + PDF export)
+src/admin/lib/queries/issued-orders.ts
+src/admin/lib/entityTypeLabels.ts        (add "issued_order" Czech label)
+src/admin/AdminApp.tsx                    (lazy routes for detail/new)
+src/__tests__/issued-orders.test.ts
+```
+
+**Tech stack:** Fastify 5, Prisma 7 (MySQL), Zod 4, React 19 + MUI v7, React
+Query, Puppeteer (PDF), Vitest. All new code follows the audited conventions
+(success/error helpers, `parseBody`/`parseId`, shared Zod coercers, broad query
+invalidation, deterministic ordering with an `id` tiebreak, locked
+read-modify-write for numbering).

+
+`draft`, `sent`, `confirmed`, `completed`, `cancelled`
+(Czech labels: _Koncept · Odeslaná · Potvrzená · Dokončená · Stornovaná_.)
+
+---
+
+## Numbering
+
+A dedicated sequence, exactly like invoices:
+
+- New `number_sequences` type string `"issued_order"` (unique on `(type, year)`,
+  as the table already enforces). Separate from `"shared"` and `"invoice"`.
+- New `company_settings` columns:
+  - `issued_order_number_pattern` VARCHAR default `"{YY}{CODE}{NNNN}"`
+  - `issued_order_type_code` VARCHAR default `"72"` (orders use `71`, invoices
+    `81`; `72` is free and configurable).
+- New functions in `src/services/numbering.service.ts`, reusing the existing
+  `applyPattern` + `getNextSequence` (`SELECT … FOR UPDATE` lock, P2002
+  first-of-year retry):
+  - `generateIssuedOrderNumber(tx)` — atomically consumes the next number.
+  - `previewIssuedOrderNumber()` — non-consuming peek (for the create form).
+  - `releaseIssuedOrderNumber(year, number)` — decrement only if the deleted PO
+    held the current highest number that year (gap prevention), mirroring
+    `releaseInvoiceNumber`.
+- The number is **assigned at creation**, including for a `draft`. Deleting a PO
+  releases the number per the rule above.
+
+---
+
+## Backend API
+
+### Schema — `src/schemas/issued-orders.schema.ts`
+
+`CreateIssuedOrderSchema`, `UpdateIssuedOrderSchema`, `IssuedOrderItemSchema`,
+built **only** from the shared coercers in `src/schemas/common.ts`:
+
+- `customer_id` → `nullableIntIdFromForm`
+- `quantity` → `positiveNumberFromForm`; `unit_price` → `nonNegativeNumberFromForm`
+- `vat_rate` → `numberInRange(0, 100)`
+- `order_date` / `delivery_date` → `isoDateString` (lenient)
+- text fields → `z.string().max(...)`; optional email-like none here
+- Czech user-facing messages; English identifiers.
+
+**No** raw `z.union([z.number(), z.string()]).transform(Number)` — that idiom is
+banned (silent `NaN`).
+
+### Service — `src/services/issued-orders.service.ts`
+
+Plain exported async functions returning `{ data }` or `{ error, status }`:
+
+- `listIssuedOrders(params)` — paginated; filters `status`, `customer_id`,
+  `search` (po_number / supplier name); whitelist sort
+  (`id`/`po_number`/`status`/`order_date`/`created_at`) with a deterministic
+  **`{ id }` tiebreak**; each row enriched via `computeIssuedOrderTotals`.
+- `getIssuedOrder(id)` — full detail with items, supplier name, and
+  `valid_transitions`.
+- `createIssuedOrder(body)` — inside `prisma.$transaction`:
+  `generateIssuedOrderNumber(tx)` → insert header → batch-insert items.
+- `updateIssuedOrder(id, body)` — validates the status transition against
+  `VALID_TRANSITIONS`; replaces items (delete-all + recreate) only while the doc
+  is editable (`draft`/`sent`); blocks any `po_number` change.
+- `deleteIssuedOrder(id)` — delete (items cascade) then
+  `releaseIssuedOrderNumber(year, po_number)`.
+- `computeIssuedOrderTotals(items, applyVat, docRate)` — **NET + VAT-on-top,
+  rounded per line before accumulation** (same shape as `computeInvoiceTotals`):
+  `base = qty × unit_price`; `lineVat = round(base × rate/100)` when
+  `applyVat`; `subtotal = Σ base`, `vat = Σ lineVat`, `total = subtotal + vat`.
+  Falls back line `vat_rate` → doc `vat_rate` → 21.
+- `getNextIssuedOrderNumber()` — proxies `previewIssuedOrderNumber()`.
+
+`VALID_TRANSITIONS`:
+
+```
+draft     → [sent, cancelled]
+sent      → [confirmed, cancelled]
+confirmed → [completed, cancelled]
+completed → []      // terminal
+cancelled → []      // terminal
+```
+
+### Routes — `src/routes/admin/issued-orders.ts`
+
+Registered in `src/routes/admin/index.ts`. Every handler uses `success()`/
+`error()`, `parseBody(Schema, …)`, `parseId((request.params as any).id, reply)`,
+and `logAudit` with a **new** entity type `"issued_order"` (create/update/delete,
+with `oldValues`/`newValues`). Adding this entity type requires also registering
+its Czech label in `src/admin/lib/entityTypeLabels.ts` (keyed to the server's
+`EntityType` value), per the single-source-of-truth convention.

+
+## PDF export
+
+> **As-built (2026-06-09):** rather than the custom/compact layout this section
+> originally sketched, the issued-order PDF was **rebuilt on the shared
+> invoice / order-confirmation red-accent (#de3a3a) template** (`src/routes/admin/issued-orders-pdf.ts`),
+> titled **OBJEDNÁVKA**, for visual consistency with the rest of the document
+> suite. Because a PO is a buying document, the direction is **flipped vs an
+> invoice**: the selected **customer record renders as "Dodavatel" (supplier)**
+> and **your company as "Odběratel" (buyer)**. It is generated **on demand** and
+> streamed as `application/pdf` — **no NAS persistence**. Sanitization,
+> on-demand/no-NAS behavior, and the NET+VAT-on-top totals below are unchanged.
+
+New route + template `src/routes/admin/issued-orders-pdf.ts`, reusing
+`htmlToPdf` (Puppeteer) from `src/utils/pdf.ts`:
+
+- **Dodavatel (supplier) block** = the selected `customers` record (name,
+  IČO/`company_id`, DIČ/`vat_id`, address). **Odběratel (buyer) block** = your
+  company (`company_settings`: name, IČO, DIČ, address, logo as base64).
+- Body: items table → VAT recap grouped by rate → **NET total + VAT + gross**.
+- `cs` / `en` strings selected by `language`. Czech date/currency via the
+  existing formatters.
+- `notes` passed through the **same** `cleanQuillHtml` + DOMPurify sanitization
+  used by invoices/orders before going into the template (mandatory for any new
+  rich-text-on-PDF field).
+- **v1 behavior:** generate on demand and stream `application/pdf` with
+  `Content-Disposition` filename `{po_number}.pdf`. **No NAS write.** (A future
+  `?save=1 → Objednávky vydané/YYYY/MM/{po_number}.pdf` add-on is a small,
+  isolated follow-up.)
+
+---
+
+## Frontend
+
+- **`src/admin/pages/Orders.tsx` — add `Vydané | Přijaté` tabs** using the same
+  MUI Tabs pattern as `Invoices.tsx`. The current orders list moves **verbatim**
+  into the **Přijaté** tab — every hook, mutation, `invalidate` array, validation,
+  and permission check preserved unchanged; only presentation is reorganized. The
+  **Vydané** tab renders the new list.
+  _(As-built: `Orders.tsx` became a **parent shell** that owns the `PageHeader` +
+  the shared month/year selector + the tabs; `IssuedOrders.tsx` (Vydané) and
+  `OrdersReceived.tsx` (Přijaté) are **content-only children** receiving `month`/`year`
+  props. `OrdersReceived`'s create modal is **hoisted** to the shell via
+  `createOpen`/`setCreateOpen`, the ReceivedInvoices pattern. **No KPI/stat cards**
+  on the Orders landing — deliberate, since orders have no paid/overdue semantics.)_
+- **Vydané list** — `DataTable` columns: `po_number`, supplier (customer name),
+  status chip (color per status), `order_date`, total (currency), actions (open,
+  **Export PDF**, delete). `FilterBar` with status + customer `Select`s and search
+  at standard widths; pagination + sortable headers; an "Vytvořit objednávku
+  vydanou" button gated on `orders.create`.
+- **`src/admin/pages/IssuedOrderDetail.tsx`** (lazy routes `/orders/issued/new`
+  and `/orders/issued/:id` in `AdminApp.tsx`): supplier `Select`, `order_date` /
+  `delivery_date` `DateField`s, currency / VAT rate / `apply_vat`, a **line-items
+  table** (add/remove rows + `@dnd-kit` reorder, like `InvoiceDetail`), `RichEditor`
+  notes, internal notes, `delivery_terms` / `payment_terms`, `issued_by`, **live
+  totals** (net / VAT / gross), status-transition buttons, and an **Export PDF**
+  button gated on `orders.export`. Top-level sections wrapped in `<PageEnter>`;
+  imports come from the `ui/` kit.
+- **Queries** `src/admin/lib/queries/issued-orders.ts` — `issuedOrderListOptions`,
+  `issuedOrderDetailOptions`, `issuedOrderNextNumberOptions`. All mutations
+  invalidate the **broad `["issued-orders"]`** domain key.
+- **Rules of Hooks:** all hooks run before any early permission `return`
+  (`<Forbidden/>`/`<Navigate/>` go after every hook) — `npm run lint` enforces
+  `react-hooks/rules-of-hooks` as an error.
+- Sidebar nav unchanged — one "Objednávky" item; the split lives in the tabs.
+
+---
+
+## Permissions
+
+Reuse the existing `orders.*` set for the Vydané tab:
+
+- `orders.view` — list + detail + PDF view
+- `orders.create` — create + next-number preview
+- `orders.edit` — update
+- `orders.delete` — delete
+- `orders.export` — PDF export (already seeded)
+
+This mirrors invoices (issued + received share one `invoices.*` set) and needs
+**no permission migration**. _(Future option, out of scope for v1: a dedicated
+`purchase-orders._` set via a seed + migration if purchasing must be locked down
+separately from sales orders.)\*
+
+---
+
+## Status lifecycle
+
+`draft → sent → confirmed → completed`, plus any non-terminal → `cancelled`.
+
+- **Editable** (header + items): `draft`, `sent`.
+- **Read-only except a permitted status change**: `confirmed`, `completed`,
+  `cancelled`.
+- Enforced server-side by the `VALID_TRANSITIONS` guard in the service; the detail
+  page only renders buttons for valid next states.
+
+---
+
+## Testing
+
+`src/__tests__/issued-orders.test.ts`, against the real **`app_test`** DB via
+`buildApp()` (no Prisma mocks):
+
+- **Numbering:** sequential allocation; release-only-if-highest on delete; the
+  generated number matches the configured pattern.
+- **Create + totals:** create with multiple items, assert NET+VAT-on-top totals
+  with **per-line rounding pinned to exact 2-decimal values**; mixed per-line VAT
+  rates; `apply_vat=false` zeroes VAT but preserves the NET subtotal.
+- **Status transitions:** every valid transition succeeds; invalid transitions
+  return the proper error; items become read-only after `confirmed`.
+- **Permissions:** each endpoint rejects a caller lacking the required `orders.*`
+  permission (not bare auth).
+- **PDF:** `GET /:id/pdf` returns `200` with `content-type: application/pdf`.
+
+---
+
+## Migration
+
+A single `prisma migrate dev --name issued_orders`:
+
+1. Creates `issued_orders` and `issued_order_items` tables + the
+   `issued_orders_status` enum.
+2. Adds `issued_order_number_pattern` and `issued_order_type_code` columns to
+   `company_settings` with SQL defaults (`"{YY}{CODE}{NNNN}"`, `"72"`).
+
+Per project rules: **ask the user to stop the dev server first**; commit both
+`schema.prisma` and the generated migration folder; run `prisma generate`. No raw
+SQL on prod — the column defaults ship inside the migration's `migration.sql`.
+
+**Quality gates before "done":** `npx tsc -b --noEmit`, `npm run build`,
+`npx vitest run`, `npm run lint` (0 errors).
+
+---
+
+## Future phases (explicitly out of scope for v1)
+
+- **Procurement links:** PO ↔ warehouse goods receipt (`sklad_receipts`) and
+  PO ↔ received invoice matching (ordered → received → invoiced rollups), with
+  Odin pre-filling a received invoice from a PO.
+- **NAS persistence** of the generated PO PDF (`?save=1`).
+- **Dedicated `purchase-orders.*` permission set.**
+- **Scope sections** (CZ/EN rich-text blocks) if POs ever need narrative content.

+-- Audit schema hardening (from the 2026-06-09 codebase audit).
+--
+-- ⚠️ PENDING — NOT YET APPLIED. Review, then apply with the dev server stopped:
+--   npx prisma migrate deploy        (prod / already-tracked)
+--   -- or, in dev, `npx prisma migrate dev` will pick it up as pending.
+--
+-- What this does:
+--   • Warehouse line→header relations now CASCADE on delete (deleting a
+--     receipt/issue/inventory session removes its lines/attachments).
+--   • Warehouse line→master-data (item/batch/location) and the financial FKs
+--     (invoices/orders/projects/quotations → customer/order/quotation) are now
+--     explicit ON DELETE RESTRICT — preventing deletion of a referenced master
+--     record / orphaning of a financial record. (Some of these were previously
+--     the optional-relation default SET NULL; RESTRICT is the safer intent.)
+--   • UNIQUE on warehouse document numbers (receipt_number/issue_number/
+--     session_number) — like every other document-number column.
+--   • New indexes on hot FK filters (sklad_issues/receipts, bank_accounts).
+--
+-- ⚠️ BEFORE APPLYING ON PRODUCTION, verify existing data won't violate the new
+--    constraints: no DUPLICATE non-null receipt/issue/session numbers (else the
+--    UNIQUE index fails), and no rows that would break the RESTRICT FKs. Test on
+--    a copy first.
