+# Possible Improvements — UX & Consistency Review
+
+_A prioritized UX review of boha-app, grounded in 104 verified, code-referenced findings._
+

+> reviewers across 5 feature domains and 11 cross-cutting UX dimensions (155 raw findings),
+> deduplicated them into 118 unique items, then **adversarially re-checked every finding

+> documented decision (CLAUDE.md). What remains are 104 findings each confirmed in the
+> source, with file references kept intact so they can be acted on directly. Read §1–§3 for
+> the opinion and the plan; §4 is the full catalogue by theme; §5 is suggested sequencing.
+>
+> **Independently re-verified (2026-06-24):** a second adversarial pass (9 parallel
+> verifiers, different model) re-checked all 104 findings against the source:
+> **100 confirmed, 4 partial, 0 refuted.** The partials were factual nits (a couple of
+> miscounts, one wrong fix target, one mis-cited import), corrected inline in this

+## 1. Executive Summary
+
+boha-app is a **mature, broad, and genuinely well-built** back-office system. The bones are excellent: there is a real component kit (`src/admin/ui/`), shared document modules, a single-source-of-truth status module (`documentStatus.ts`), a global React Query cache with disciplined invalidation conventions, timezone-safe date handling, edit-locking on documents, and an accessibility-aware theme. Most of the "hard" platform work is done and done well. This is not a rescue job — it is a **polish-and-converge job**.
+
+That said, the owner asked the right question. The single dominant theme across these findings is **consistency debt: the app does the same thing several different ways, and the variants disagree in ways the daily user feels.** Almost every cluster below is a story of "module A got it right, module B is an older or forked copy that drifted." The codebase even documents this pattern against itself — `documentStatus.ts` exists _because_ per-page status maps drifted; `useUnsavedChangesGuard` exists _because_ the dirty-check was copy-pasted; CLAUDE.md explicitly says "extend, never fork." The findings show those rules are followed in the newest modules (offers, issued orders) and quietly violated in the older twins (invoices, orders, attendance-admin, projects, warehouse).
+
+Why this matters: the user's mental model breaks at the seams. Marking an invoice paid from the **detail** page leaves a project's order-status label stale, but doing it from the **list** page refreshes it. The "create" button **navigates to a page** on one Orders tab and **opens a modal** on the other. A failed list fetch shows "no records yet" — which can convince a user a customer has zero invoices when the server actually errored. Validation errors appear **inline under the field** on the supplier modal but **as a 4-second toast** on its mirror-image customer modal. None of these is catastrophic alone; collectively they make a strong app feel "not quite finished" and erode trust in what's on screen.
+
+**The five highest-leverage moves, in order:**
+
+1. **Stop showing stale data after writes.** Define one canonical React Query invalidation set per document family and apply it to _both_ list and detail mutations. Today detail-page edits invalidate fewer domains than their list twins (`OrderDetail`, `InvoiceDetail`, `DashProfile`, leave-cancel). Small effort, removes a whole class of "why is this number wrong" confusion. _(Cluster: data-freshness)_
+
+2. **Guard the irreversible actions that currently aren't.** Marking an invoice **"Zaplaceno"** is a single unconfirmed chip click and is _terminal_ — the one truly irreversible document transition with **no** confirm, while every reversible status change has one. Same inversion in the warehouse: **"Potvrdit"** (posts stock) has no confirm but its **undo** does. And the **Aktivní/Neaktivní** chips are secret one-click toggles that fail silently on error. _(Cluster: destructive actions)_
+
+3. **Fix list-page failure and loading states.** No list page reads `isError`, and there is no global `QueryCache.onError`, so failed fetches fall through to the **empty state** — actively misleading. Add a global error toast plus a distinct inline error. _(Cluster: loading/empty/error)_
+
+4. **Make the app usable on a phone.** The shared `Tabs` uses MUI's non-scrolling `variant="standard"`, so the 5 status-filter tabs on Offers/Invoices simply **clip off-screen and become unreachable** at ~360px — a one-prop fix that touches every status filter. Modals never go full-screen on phones. _(Cluster: mobile)_
+
+5. **Converge the shared primitives the app already owns.** Route the forked dirty-guards, status maps, empty states, page headers, save buttons, and PDF openers back through their canonical implementations. This is the structural fix that prevents the other four from re-drifting. _(Cluster: forked modules)_
+
+The rest of this report groups all findings by theme, gives a prioritized action table, and then lists every finding with its file references intact so they can be acted on directly.

+
+## 2. Top Themes
+
+### Theme A — Data-freshness drift (the trust killer)
+
+React Query invalidation is the app's nervous system, and CLAUDE.md lays out clear rules ("invalidate every domain that embeds the data"). The newest modules obey; older and raw-`apiFetch` paths don't. **List pages and their own detail pages invalidate different domain sets** because list pages use manual `invalidate` arrays while detail pages use `useApiMutation` arrays, and the two drifted independently. The result is subtle: a value that is correct after editing it one way is stale after editing it the identical other way. Converge on **one named invalidation constant per family** and reuse it on both surfaces. The dashboard already solved the "many domains feed me" case with `refetchOnMount: "always"` — apply the same backstop to the audit log.
+
+### Theme B — Destructive & risky actions are gated by consequence-inverted logic
+
+The pattern across the app is sound — `ConfirmDialog` everywhere — but the gating is **inversely correlated with actual consequence** in the few places it matters most. The _irreversible_ transitions (invoice→paid, warehouse "Potvrdit" posts stock) have **no** guard, while their _reversible_ counterparts (cancel document) get a full danger confirm. Several state changes hide as **chip toggles with no affordance** and **no `onError`**, so a rejected toggle silently reverts with zero feedback. And the "wipe the entire audit log" case uses the same low-key modal as "trim 30-day rows." Converge on: irreversibility → stronger friction, never weaker; every mutating control announces itself and reports its errors.
+
+### Theme C — Forms & save UX speak three dialects
+
+Validation is **inline-under-field** in some forms and **transient toast** in others — and _mirrored screens disagree_ (supplier modal inline vs customer modal toast; trip editor inline vs admin-trip editor toast; received-invoice bulk-review inline vs its single-edit toast). Enter submits page forms but **never** submits a shared-`Modal` form. Save buttons **spin** in document pages but only **swap text** elsewhere, and dual-save warehouse forms can't tell you which action is running. Failed validation never **moves focus** to the bad field. Converge on: inline `<Field error>` for validation, toasts only for transport/server failures, `<form onSubmit>` in the shared Modal, one save affordance, and focus-the-first-error.
+
+### Theme D — Unsaved-work protection is partial and fork-ridden
+
+The shared `useUnsavedChangesGuard` is used by exactly two pages; `OrderDetail` and `InvoiceDetail` **re-implement it inline**, and `ProjectDetail`, `CompanySettings`, all three warehouse forms, and `AttendanceCreate` have **no guard at all** — a refresh discards a 15-line receipt silently. Worse, _every_ guard only catches `beforeunload`, so clicking the in-app **"Zpět"** or a sidebar link — the most common way to leave — discards edits with no prompt (this one needs a router upgrade). And `InvoiceDetail` has **no edit-lock** while its siblings do, so two users can clobber each other's invoice line items.
+
+### Theme E — Loading, empty & error states have no single grammar
+
+Three different loading behaviors for the _same_ "change the month" action (dim / nothing / flash). Empty states built two ways (`<EmptyState>` vs hand-rolled `Box+Typography`). 40 pages **blank the whole page to a centered spinner** (layout shift) instead of keeping chrome; there are **zero** real MUI `<Skeleton>`s despite identifiers literally named `showListSkeleton`. The dashboard hand-rolls its own spinner. And the big one: **failed fetches render as empty**, not as errors.
+
+### Theme F — Navigation & information architecture has thin orientation
+
+Every browser tab reads **"Admin"** (no per-page title), there are no breadcrumbs, the back control is built **four different ways**, and `Received-order` detail sends you back to the **wrong Orders tab**. Master data is scattered across four nav sections; "Zákazníci" lives at the misleading URL `/offers/customers`; `settings.templates` opens the gear then **bounces you to the dashboard**; and there are three different "access denied" experiences. None blocks work, but together they make deep pages feel un-anchored.
+
+### Theme G — Mobile is a second-class citizen in specific, fixable spots
+
+Status-filter tabs **clip and become unreachable** on phones. Modals never go full-screen. Long full-page editors keep **Save only at the top**, so phone users scroll all the way back up to save. Warehouse line-items lose the labeled card-per-row layout the document editor has — worst exactly where shop-floor mobile use is likely. `FilterBar` children mix fixed and growing flex bases, leaving dead space.
+
+### Theme H — Microcopy & localization inconsistency
+
+The goods-receipt module is named **four ways** (Příjmy / Nový příjem / Příjmové doklady / Příjemka) and "Příjmy" also means _financial income_. "Cancelled" is spelled two ways in the same status file. Create verbs split three ways. The busy label has five competing forms plus a `"Chyba pripojeni"` diacritics typo. Autocompletes leak English **"No options"** in an otherwise fully-Czech app. Several prices bypass cs-CZ formatting (period decimals, no currency).
+
+### Theme I — Accessibility gaps in the hot paths
+
+Clickable table rows aren't keyboard-operable (warehouse records literally can't be opened by keyboard). Search boxes are placeholder-only with no accessible name across ~13 pages. The desktop line-item grid is unlabeled while the mobile card is fully labeled. No skip-to-content link, so keyboard users tab the whole sidebar on every navigation.
+
+### Theme J — Bundle & performance
+
+MUI + Emotion sit in the **781 kB entry chunk**, so every patch release busts the cached UI vendor code and daily users re-download ~232 kB gzip of unchanged MUI. The Dashboard and its 7 subcomponents are bundled into the entry chunk and downloaded **on the Login screen**. No route-transition progress bar, no link prefetch.

+## 4. Detailed Findings by Area
+
+### 4.1 Data-freshness — stale data after mutations
+
+- **Detail-page mutations invalidate fewer domains than their list twins.** `OrderDetail` status/notes/delete (`OrderDetail.tsx:162,168,177`) invalidate only `[orders,invoices]` while the `ReceivedOrders` list delete (`ReceivedOrders.tsx:175`) uses `[orders,offers,projects,invoices]`. `InvoiceDetail` save/status/delete (`InvoiceDetail.tsx:1054,1067,1073`) use `[invoices,orders]` while the `Invoices` list adds `projects` (`Invoices.tsx:328,352`). **Why it matters:** marking an invoice paid or changing an order status from the _detail_ page leaves `ProjectDetail`'s `order_status` label (`ProjectDetail.tsx:571`) and the source offer stale until staleTime/refocus. **Fix:** define one canonical set per family (e.g. `[offers,orders,issued-orders,projects,invoices]`) and apply to both surfaces; `OfferDetail`/`Offers` are the consistent reference to copy.
+
+- **Self-profile edit refreshes fewer domains than an admin editing the same user.** `DashProfile` (`DashProfile.tsx:225-226`) invalidates only `[dashboard,users]`, but admin Users edit uses `USER_INVALIDATE=[users,trips,attendance,leave-requests,leave,projects]` (`Users.tsx:117-124`). **Why:** your display name is embedded in trips/attendance/leave/projects (none keyed under `[users]`), so renaming yourself leaves it stale there. **Fix:** export `USER_INVALIDATE` from a shared module and reuse it in `DashProfile`.
+
+- **Cancelling a leave request omits the `[users]` balance invalidation that create/approve include.** Cancel (`LeaveRequests.tsx:90`) invalidates `[leave-requests,leave,attendance]`; create (`Attendance.tsx:305`) and approve/reject (`LeaveApproval.tsx:164,177`) add `users,dashboard`. **Why:** the genuinely-stale gap is `[users]` balance/history when an approved future request is cancelled (the `[dashboard]` part self-heals via `refetchOnMount`). **Fix:** hoist a shared `LEAVE_INVALIDATE` set across all three flows.
+
+- **Audit Log is never invalidated by the mutations that write audit rows.** `logAudit()` runs on every mutation, but `[audit-log]` is invalidated only by plan flows (`usePlanWork.ts:167`) and the page's own cleanup (`AuditLog.tsx:191`). **Why:** recent actions don't appear within the 30s default staleTime. **Fix:** add `refetchOnMount:'always'` (and `staleTime:0`) to the AuditLog page's inline `useQuery` (`AuditLog.tsx:135`), mirroring `dashboardOptions` — don't sprinkle `[audit-log]` into dozens of arrays. _(Verification note: `auditLogOptions` in `auditLog.ts` is dead code — nothing imports it; either delete it or wire the page onto it and put the option there.)_
+
+- **Odin invoice import invalidates only `[invoices]`, not `[suppliers]`/`[company-settings]`.** `OdinChat.tsx:362` vs manual `[invoices,suppliers,company-settings]` (`ReceivedInvoices.tsx:331,341`). **Why:** an Odin import that introduces a new vendor name won't appear in the `[suppliers]`-keyed autocomplete until staleTime expires. **Fix:** use the same set on both paths (they POST to the same endpoint).
+
+- **Received-invoice supplier picker is disjoint from the warehouse/issued-order supplier registry.** Received invoices use a free-text `string[]` under `[suppliers]` → `/received-invoices/suppliers` (`common.ts:22-28`); issued orders/warehouse use the structured `sklad_suppliers` table (`issued-orders.ts:76`, `warehouse.ts:241`). **Why:** a vendor added in Warehouse→Suppliers never shows when entering a received invoice, and vice-versa — same conceptual entity, two disjoint stores. **Fix:** don't force an FK (keep one-off vendors as quick free-text), but **union** `sklad_suppliers` names into the received-invoice autocomplete source.
+
+### 4.2 Destructive & risky actions — confirmation and undo
+
+- **Marking an invoice "Zaplaceno" is a single unconfirmed chip click — the only irreversible transition with no guard.** In both invoice lists the chip instantly PUTs `status=paid` with no confirm and no undo (`Invoices.tsx:339-359,550-562`, `ReceivedInvoices.tsx:668-680`); for issued invoices "paid" is terminal (detail goes read-only, row undeletable, `InvoiceDetail.tsx:1220-1314`). Every _detail_ page gates status changes behind a `ConfirmDialog`, but this one doesn't, and the chip only differs from a static one by a pointer cursor. **Fix:** route the chip click through a `ConfirmDialog` ("Označit fakturu … jako zaplacenou?") or an undo toast, and add a hover/tooltip affordance.
+
+- **Aktivní/Neaktivní chips are hidden one-click toggles with no affordance, and fail silently.** On Vehicles, Users, Warehouse Locations and Suppliers the `StatusChip` is secretly an `onClick` toggle with no tooltip/label (`Vehicles.tsx:263`, `Users.tsx:288`). Deactivation fires on one click while the less-destructive delete gets a full `ConfirmDialog`. The Vehicles/Users toggle mutations declare only `onSuccess`, **no `onError`** and no try/catch (`Vehicles.tsx:146-160`, `Users.tsx:162-171`), so a rejected toggle gives zero feedback and the chip silently reverts. **Fix:** make activation an explicit labelled control (switch/menu action) with a tooltip; add a deactivation confirm for user/vehicle; add `onError` toasts. (`WarehouseLocations`/`WarehouseSuppliers` already toast via try/catch — copy them.)
+
+- **`ConfirmDialog` in-flight `loading` is applied inconsistently — some dialogs allow duplicate submits.** `IssuedOrderDetail` passes `loading` to both status and delete dialogs (`:958`); `OrderDetail`/`InvoiceDetail` pass it to delete but not status (`OrderDetail.tsx:780-790`, `InvoiceDetail.tsx:2453-2463`); Vehicles delete (`:417-429`), `AttendanceAdmin` delete (raw `apiFetch`, no `isPending`, `useAttendanceAdmin.ts:1293-1320`) and CompanySettings bank delete omit it entirely → a second click fires a duplicate request. **Fix:** pass `loading={mutation.isPending}` to every `ConfirmDialog`; convert `AttendanceAdmin`'s raw delete to `useApiMutation`; standardize on `IssuedOrderDetail`'s keep-open "Zpracovávám…" convention.
+
+- **Irreversible "Potvrdit" (posts stock) has no confirm, while its reversible "Zrušit doklad" undo does.** `WarehouseReceiptDetail.tsx:354-356` commits stock movements on one click; `:508-517` requires a danger confirm to reverse it. Same single-click commit in the form's "Uložit a potvrdit" (`WarehouseReceiptForm.tsx:445`). **Why:** the gating is inverted relative to consequence; a misclick commits stock. **Fix:** add a `ConfirmDialog` before "Potvrdit" (and ideally the form's commit).
+
+- **Cancellation confirms show two near-identical "Zrušit" buttons.** When the confirmed action is itself a cancellation, both the dismiss and the confirm start with "Zrušit" (`WarehouseReceiptDetail.tsx:508-516`, `LeaveRequests.tsx:260-268`) — same leading word, opposite meanings (the buttons do differ visually: contained vs text). **Fix:** relabel the dismiss to "Zpět"/"Ne" via `cancelText` (`ConfirmDialog.tsx:31-33`).
+
+- **Wiping the ENTIRE audit log uses the same low-key modal as trimming old rows.** "Vše" sits in the same dropdown as "30 dní"/"90 dní" and the only warning is a 0.6-opacity caption (`AuditLog.tsx:297-319,207-218`). The backend deliberately requires a special literal to wipe everything (`routes/admin/audit-log.ts:92-109`), but the UI auto-supplies it with no extra friction. **Fix:** when "Vše" is selected, switch to danger styling, show a prominent warning, ideally require typing a confirmation word.
+
+- **Error toasts auto-dismiss after 4s identically to successes, with no history.** `AlertContext.tsx:53-70` defaults every severity to 4000ms; a long Czech validation message vanishes as fast as "Uloženo," with no toast history (`AlertContainer.tsx:20-27`). **Fix:** key the default off severity — error/warning longer or sticky-until-dismissed, success ~4s.
+
+### 4.3 Error & message feedback fidelity
+
+- **Raw English/technical error strings leak into Czech toasts on ~30 pages.** A helper `apiErrorMessage(err, fallback)` converts client-generated English ("Unauthorized", "Failed to fetch", "Invalid JSON response", "Request failed (NNN)") into a Czech fallback (`mutations.ts:30-36,69-84`), but only `OfferDetail`/`IssuedOrderDetail` use it. ~30 pages do `alert.error(e instanceof Error ? e.message : "Chyba připojení")` (`Vehicles.tsx:203`, `OrderDetail.tsx:191`), passing the raw English through on dropped connections / non-JSON 500s / 401s. **Fix:** replace the inline pattern with `apiErrorMessage(e, "<Czech fallback>")` across the ~32 files. **Do not** add a blanket `useApiMutation` default `onError` — pages call `mutateAsync` inside try/catch and also reset local state there, so a default handler would double-toast.
+
+### 4.4 Unsaved-changes & data-loss protection
+
+- **The dirty guard is absent on heavy editors and forked twice.** Shared `useUnsavedChangesGuard` is used only by `OfferDetail`/`IssuedOrderDetail`; `OrderDetail` (`:130-143`) and `InvoiceDetail` (`:942-958`) re-implement `isDirty`+`beforeunload` inline; `ProjectDetail`, `CompanySettings`, `WarehouseIssueForm/ReceiptForm/InventoryForm` and `AttendanceCreate` register **no guard at all** — a refresh discards everything typed. **Fix:** route the two forks through the shared hook and add it to the six unguarded editors.
+
+- **Dirty guards block only tab-close, not in-app navigation.** Every guard registers only `beforeunload` (`useUnsavedChangesGuard.ts:25-33`), which doesn't fire on React-Router navigation — so the in-app "Zpět" or a sidebar link discards edits silently. **Fix (structural):** the app uses classic `<BrowserRouter>` (react-router 6.30.3) where `useBlocker`/`usePrompt` aren't available — this needs a migration to `createBrowserRouter`/`RouterProvider` (or a custom nav-intercept context), then centralize the blocker inside the shared hook.
+
+- **Always-editable page forms offer no explicit Discard.** Modals have "Zrušit" and `WarehouseItemDetail` has an edit/cancel toggle that restores the snapshot (`:247-269`), but `ProjectDetail` (only Uložit+Smazat, `:343`) and `CompanySettings` (only Uložit, `:647`) give no way to abandon edits — you must reload (and they don't even warn). **Fix:** add a "Zrušit změny" button that restores the loaded snapshot from query cache.
+
+- **Invoices have no edit-lock while offers and issued orders do (multi-user clobbering).** `OfferDetail`/`IssuedOrderDetail` acquire a server lock, heartbeat, render `LockBanner` and force read-only when another user holds it; `InvoiceDetail` imports none of it (`:22-88`), so two users can clobber each other's line items (last-save-wins). Same gap for received-order notes on `OrderDetail`. **Fix (structural):** the _client_ pieces exist (`useDocumentLock`+`LockBanner`) but the _server_ trio does **not** — needs a migration adding `locked_by`/`locked_at` to invoices (and orders), a lock/heartbeat/unlock route trio + `locked_by` enrichment in the detail endpoint (mirror `issued-orders.ts:138-245`), then wire the existing hook + banner.
+
+### 4.5 Form validation & submission
+
+- **Validation is inline in some forms, transient toasts in others — and mirrored screens disagree.** Inline `<Field error>` camp: Trips, Users, Vehicles, WarehouseSuppliers, OfferDetail. Toast camp: ProjectDetail, AttendanceCreate, CompanySettings, OffersCustomers, TripsAdmin, ReceivedInvoices-edit. The disagreements: supplier modal inline (`WarehouseSuppliers.tsx:266-270`) vs its mirror customer modal toast (`OffersCustomers.tsx:338-341`); regular trip editor inline `end_km>start_km` (`Trips.tsx:294-300`) vs admin trip editor toast (`TripsAdmin.tsx:485-490`); received-invoice bulk-review inline per-row (`:431-446`) vs single-edit toast (`:508-519`). **Fix:** standardize on inline `<Field error>`; reserve toasts for server/transport failures.
+
+- **Enter submits page forms but never any shared-Modal form.** `Modal` renders children in `DialogContent` with an `onClick` button (default `type=button`) and no surrounding `<form>` (`Modal.tsx:84,92`), so Enter never submits a modal. `OfferDetail` even hand-rolled an `onKeyDown` Enter workaround (`:1059-1061`). **Fix:** wrap `DialogContent`+`DialogActions` in `<form onSubmit>`, make the primary action `type=submit`, mark secondary/in-content buttons `type=button`, and remove the workaround.
+
+- **Failed validation doesn't move focus to the first invalid field nor announce to AT.** Handlers just `setErrors` and return (`Vehicles.tsx:192-197`); the `Field` error is a plain caption wired via `aria-describedby`/`aria-invalid`, not `aria-live`/`role=alert` (`Field.tsx:81-89`). In a long modal the error can be off-screen. **Fix:** after `setErrors`, focus+`scrollIntoView` the first errored field and render the inline error with `role=alert`; centralize in `Field.tsx`/`Modal.tsx`.
+
+- **Required-asterisk marking is inconsistent with what's validated; DateField/TimeField can't show an error border.** `Field` paints the asterisk only when `required` is passed (`Field.tsx:74`), but it's applied unevenly: `WarehouseIssueForm` validates Projekt-required with no asterisk (`:474` vs `:328-329`); `ProjectDetail` validates Název-required with no asterisk (`:377` vs `:192`); `DateField`/`TimeField` take no `error` prop so a failed required date only reddens helper text, not the border. **Fix:** make `required` the single source of truth (drives asterisk + ideally validation); thread an `error` prop through `DateField`/`TimeField`.
+
+- **Save-button feedback differs (spinner vs text swap); dual-save warehouse forms don't show which action is running.** Document pages render a `CircularProgress` and track `savingAction` so only the clicked button spins (`OfferDetail.tsx:764`); most other forms just swap to text (`ProjectDetail.tsx:346`). On `WarehouseIssueForm` both save buttons swap to identical "Ukládání..." and disable (`:455-465`) — you can't tell which is in flight. **Fix:** adopt one affordance app-wide (spinner+disabled with per-action targeting); spin only the clicked warehouse action.
+
+- **Note typed in the create-project modal is saved to the legacy column and shown as non-editable.** The "Přidat projekt" modal's Poznámka writes `projects.notes` (`Projects.tsx:164`, `projects.service.ts:222`), but `ProjectDetail` renders that column read-only under "Starší poznámka (před zavedením systému)" (`:477,491`). So a note typed at creation is instantly mislabeled as legacy and uneditable, while the real editable `project_notes` system lives only on the detail page. **Fix:** drop the Poznámka field from the create modal, or route the create-time note through `createProjectNote`.
+
+### 4.6 Loading, empty & error states
+
+- **Failed list fetches silently render the empty state.** `usePaginatedQuery` exposes `isError`/`error` (`:47-48`) but no list page reads them, and `queryClient.ts` has no `QueryCache.onError`. So a 500/network drop falls through to the `DataTable` empty slot — Projects shows "Zatím nejsou žádné projekty" (`:480`). Detail pages handle errors loudly; `WarehouseReports.tsx:350` shows an inline `<Alert severity=error>`. **Fix:** add a `QueryCache.onError` toast and/or render an inline error distinct from empty when `isError`, with retry wired to `refetch`.
+
+- **Empty states built two ways, and clickable-CTA vs text-only split.** Shared `<EmptyState>` is used by document/warehouse lists, but Projects/Vehicles/Users hand-roll `Box(textAlign,py:6)+Typography+Button` (`Projects.tsx:471/480`, `Vehicles.tsx:323`, `Users.tsx:350`), reinventing the `action` prop. Offers renders a clickable "Vytvořit první nabídku" (`:835`) while Invoices/ReceivedInvoices only name the button in description text (`Invoices.tsx:770`). **Fix:** migrate hand-rolled empties to `<EmptyState title description action>` and standardize the clickable-create-CTA convention.
+
+- **Empty-state microcopy is inconsistent** (fragments vs sentences, trailing-period split, three filtered-empty phrasings, 2nd person). Fragments with no period (`AuditLog.tsx:368`, `WarehouseReports.tsx:223,364`) vs full sentences (`AttendanceHistory.tsx:653`). Filtered-empty worded three ways: "neodpovídají filtru" (`Offers.tsx:827`) / "neodpovídají filtru." (`Projects.tsx:473`) / "neodpovídají hledání." (`ReceivedInvoices.tsx:859`). Nothing-yet mixes "Zatím nejsou žádné X." with 2nd-person "Zatím nemáte žádné žádosti" (`LeaveRequests.tsx:253`). **Fix:** adopt one canonical filtered-empty string, one unfiltered-empty string, one trailing-period rule.
+
+- **Changing a month/filter gives three different loading behaviors.** Document/warehouse lists dim the card via `isFetching` opacity (`Offers.tsx:815`). `TripsHistory`/`TripsAdmin` keep stale data with NO feedback (`:304-306`/`:810-812`). `AttendanceHistory` uses plain `useQuery` with no `placeholderData`, so a month change flips `isPending` and swaps the whole table for a centered spinner (`:523,646`). **Fix:** standardize on the `isFetching` card-dim; give Trips screens the dim and `AttendanceHistory` `keepPreviousData`.
+
+- **No real skeletons; 40 list pages blank the whole page to a centered spinner (layout shift); "skeleton" identifiers are misnamed.** The only first-paint affordance is `LoadingState` (centered spinner, `LoadingState.tsx:10-22`); 40 pages early-return it before rendering chrome (`Projects.tsx:267`, `Offers.tsx:492`), so title/tabs/filter bar vanish then snap in. There are zero MUI `<Skeleton>`s despite identifiers like `showListSkeleton` (`ReceivedInvoices.tsx:357`). **Fix:** render `PageHeader`+`FilterBar` immediately and confine the spinner (or a real DataTable skeleton — the `skeleton-boha` skill exists) to the table area; at minimum rename the misleading identifiers.
+
+- **Redundant sequential/stacked spinners.** First visit to a lazy section shows the Suspense fallback spinner (chunk download, `AdminApp.tsx:112`), then the page's own `isPending` shows a SECOND centered spinner. Separately `ReceivedInvoices` never early-returns: `renderKpi` shows `<LoadingState/>` (`:752`) AND the list shows one (`:846`) — two stacked spinners on cold load, where sibling `Invoices` shows one. **Fix:** render a single unified loading state per page (have lazy pages supply their own shell as the Suspense fallback).
+
+- **Dashboard hand-rolls its loading spinner and mixes empty-state styles.** `Dashboard.tsx:313-316` and `DashSessions.tsx:161-164` inline `Box+CircularProgress` (different padding/size, no aria-label) vs the shared `<LoadingState/>`. `DashTodayPlan`/`DashSessions` hand-roll Typography empties while `DashActivityFeed`/`DashAttendanceToday` use `<EmptyState>`. On the most-visited page. **Fix:** use `<LoadingState/>` and standardize card empties on `<EmptyState>`.
+
+- **Profile, 2FA and active sessions are gated behind the heavy dashboard aggregate query.** `DashProfile` and `DashSessions` render only inside `{!dashLoading && (...)}` (`Dashboard.tsx:505`), where `dashLoading` is the multi-domain aggregate (attendance+offers+invoices+orders+projects+leave). Neither block depends on that data — `DashProfile`'s 2FA comes from `totpStatusOptions`, `DashSessions` has its own query (`:74`). **Fix:** render `DashProfile`/`DashSessions` independently; gate only the data-dependent cards.
+
+- **Autocomplete pickers show English "No options."** `MuiProvider` sets only the date-picker locale, no global `csCZ` `localeText` (`:15-22`); `CustomerPicker.tsx:49`/`SupplierPicker.tsx:49` omit `noOptionsText`, so empty search shows MUI's built-in English. `ItemPicker.tsx:61` correctly sets "Žádné položky." **Fix:** add MUI `csCZ` component `localeText` (fixes every Autocomplete/pagination at once) or at minimum `noOptionsText` on the two pickers.
+
+### 4.7 List-page consistency
+
+- **Invoices/ReceivedInvoices/AuditLog search fires a query per keystroke (no debounce).** Offers/IssuedOrders/ReceivedOrders/Projects/Warehouse use `useDebounce(value,300)`, but `Invoices.tsx:282`, `ReceivedInvoices.tsx:250` and `AuditLog.tsx:202` feed the raw value into the query key — laggier and hammering the API on the busiest financial screens. **Fix:** wrap in `useDebounce` (or a shared `SearchField`).
+
+- **DataTable `onRowClick` rows aren't keyboard-operable; row-click only exists on warehouse lists.** Warehouse Items/Issues/Inventory/Receipts open via clicking the row (their _only_ entry), but Offers/Invoices/Orders/Projects/Users/Vehicles don't set `onRowClick`. Worse, the clickable `TableRow` has no `tabIndex`/`role`/`onKeyDown` (`DataTable.tsx:285-303,137-161`), so a keyboard user **cannot** open a warehouse record. `OdinSidebar` already has the correct pattern (`:126-140`). **Fix:** add `role="button"`, `tabIndex=0`, Enter/Space handling when `onRowClick` is set; then pick one row convention.
+
+- **Column sorting absent on warehouse-document, audit-log and trips tables that look sortable.** `DataTable` renders sort headers only when columns carry `sortKey` and the page wires `onSort`. Offers/Invoices/Orders/Projects/WarehouseItems do; `WarehouseIssues.tsx:258`, `AuditLog.tsx:364`, `TripsAdmin.tsx:815` and WarehouseReceipts don't — you can't reorder warehouse docs by date/status nor the audit log by user, with no cue distinguishing a sortable header from a dead one. **Fix:** wire `useTableSort`+`sortKey`+`onSort` into the large paginated tables.
+
+- **Sibling Order tabs disagree on the "all" status label.** `IssuedOrders` uses "Všechny" (`:60`), `ReceivedOrders` "Všechny stavy" (`:54`) under the same parent Orders tabs. **Fix:** unify the label (don't force the Tabs-vs-Select control change — IssuedOrders deliberately keeps a Select).
+
+- **Filter baseline diverges: search/date/reset missing where needed.** WarehouseIssues/Receipts have search+status+date-range+reset; `WarehouseInventory.tsx:149` has only a status dropdown (no search despite `session_number`); `WarehouseReservations.tsx:354` has no text search or date filter; `AuditLog.tsx:321` (5 filters) and `TripsAdmin.tsx:734` (3 filters) have **no reset**. **Fix:** standardize a list-filter baseline; add the missing search/date/reset.
+
+- **Offers/IssuedOrders filter by customer/supplier but the Invoices list cannot.** Offers has a customer Select (`:797-812`), IssuedOrders a supplier Select (`:400-415`), but the equally customer-centric Invoices list offers only free-text search (`:739-751`). **Fix:** add a customer Select (load via `offerCustomersOptions`, wire `customer_id` into list+totals; may need a small backend add).
+
+- **Count subtitle missing on Projects/Users/Vehicles/Customers and the Přijaté tab; count copy splits `czechPlural` vs hand-rolled ternary.** Projects/Users/Vehicles show a bare title (`Projects.tsx:427`, `Users.tsx:338`, `Vehicles.tsx:311`), Customers a static description (`:492`), and Vydané shows a count line but Přijaté doesn't. The plural is hand-rolled five times (`WarehouseIssues.tsx:112-114`) where `czechPlural()` exists (`formatters.ts:69`). **Fix:** add a result-count subtitle via `PageHeader`; replace the hand-rolled ternaries with `czechPlural()`.
+
+- **Many pages hand-roll the title bar instead of `PageHeader`, so multi-button headers wrap raggedly on mobile.** `PageHeader`'s `headerActionsSx` makes header buttons stack full-width on phones (`PageHeader.tsx:19-30`), but ~20 pages hand-roll `Box+Typography h4 + raw action Box` (Projects, Users, Vehicles, TripsAdmin, Attendance, AttendanceAdmin, Settings, CompanySettings). The multi-button ones (AttendanceAdmin Tisk/Vyplnit/Přidat `:179-198`; TripsAdmin Tisk/Vozidla `:699-731`) wrap into a ragged half-width grid on phones. **Fix:** route through `<PageHeader>` or wrap the action Box in `headerActionsSx`.
+
+- **Three forked invoice PDF openers → inconsistent feedback and different error copy.** Shared `useDocumentListPdf`/`useDocumentPdf` pre-opens the tab, shows a per-row spinner, guards double-clicks, handles 401 and revokes the blob URL (`useDocumentPdf.ts:37-86`); Offers/IssuedOrders use it. But Invoices reimplements it inline (`:361`), ReceivedInvoices reimplements with **no** loading state (`:561`), and InvoiceDetail forks its own (`:1175`). Same failure yields three different sentences. **Fix:** route all three through the shared hook (make the error string a parameter — received-invoice `openFile` streams a stored upload, not a generated PDF).
+
+- **Invoices LIST shows a PDF button on draft invoices, dead-ending in a 404.** Offers/IssuedOrders hide the PDF icon for drafts and InvoiceDetail's own header hides it on drafts (`:1890`), but the Invoices list renders it for every invoice gated only on permission (`:616-626`). **Fix:** gate on `inv.invoice_number` too, matching `Offers.tsx:660`/`IssuedOrders.tsx:303`.
+
+- **Customers and Suppliers directories use opposite data/search/pagination models.** Built as mirrors, but `OffersCustomers` fetches the entire list once and filters client-side with no debounce/pagination (`:159,380`), while `WarehouseSuppliers` is server-paginated, debounced, page-sized with real Pagination (`:139,449`). **Fix:** align Customers on the Suppliers model (server pagination/search), preserving instant responsiveness via `keepPreviousData`/quick debounce.
+
+### 4.8 Navigation & information architecture
+
+- **Received-order detail returns you to the wrong Orders tab.** Received orders live under Orders→"Přijaté", but `OrderDetail`'s Zpět/post-delete/fetch-error redirects all go to `/orders` with no tab, and Orders defaults to "vydane" (`Orders.tsx:78-79`) — so you land on the issued-orders list (a different doc type). IssuedOrderDetail does it right with `/orders?tab=vydane`. **Fix:** point `OrderDetail`'s links (`:116,280,399`) at `/orders?tab=prijate`.
+
+- **The "Zpět" back control is built four different ways.** No shared back primitive: document detail puts a labeled outlined Zpět on the LEFT (`OfferDetail.tsx:643`); warehouse detail puts it on the RIGHT inside PageHeader (`WarehouseItemDetail.tsx:372`); warehouse forms use an icon-only IconButton on the left (`WarehouseReceiptForm.tsx:423`); `AttendanceCreate` uses a text "← Zpět na správu" on the right (`:173`). All hardcode the list route. **Fix:** add an optional `back={{to,label}}`/`onBack` prop to `PageHeader` rendering one canonical left-aligned icon+label control.
+
+- **No per-page browser title — every tab/bookmark/history entry reads "Admin."** `index.html:22` hardcodes `<title>Admin</title>` and nothing updates it (zero `document.title` refs). With multiple tabs open (common here), the tab strip/history/bookmarks all read "Admin." **Fix:** add a `<TitleSync>` setting `document.title` per route from `navData.tsx` labels (`+ " · BOHA"`).
+
+- **No route breadcrumbs on deep detail/form pages.** Deep destinations (`/warehouse/items/:id`, `/warehouse/receipts/:id/edit`, `/orders/issued/:id`) give only one back link to a single hardcoded list, with no "Sklad › Položky › <item>" trail. Combined with the missing title, deep-page orientation is thin. **Fix:** add a lightweight section › list › record breadcrumb derived from route + `navData` metadata.
+
+- **`settings.templates` gates the Nastavení nav item but Settings bounces such users to the dashboard.** The gear shows if the user holds any of five permissions including `settings.templates`, but `canAccessSettings` checks only roles/company/system/banking and `Navigate`-to-`/` otherwise (`Settings.tsx:199-200,421-423`). So a templates-only user sees the gear, clicks, and is teleported away. Meanwhile the offer-templates editor (`/offers/templates`, `OffersTemplates.tsx:137`) has **no** nav entry — only a "Šablony" button buried in the Offers header (`Offers.tsx:750`). **Fix:** drop `settings.templates` from the Nastavení gate (`navData.tsx:486-492`) and give the templates editor a discoverable home.
+
+- **Three different "access denied" experiences.** ~40 pages render the polished `<Forbidden/>` (403 + explanation + "Zpět na Dashboard"); Settings silently `Navigate`-to-`/` (`:421-423`); Odin shows a bare unstyled line of text (`Odin.tsx:9-17`). **Fix:** standardize on `<Forbidden/>` everywhere.
+
+- **"Zákazníci" master data sits under the misleading URL `/offers/customers`.** Customers are a top-level entity referenced by offers, orders and invoices, yet the route implies a sub-resource of offers — visible in code as the `matchExclude:['/offers/customers','/offers/templates']` hack the Nabídky nav item needs (`navData.tsx:250`). **Fix:** move customers to a top-level `/customers` (redirect from the old URL), removing the hack.
+
+- **Master-data lists are scattered across four nav sections with no cross-links.** Zákazníci under Administrativa, Dodavatelé under Sklad, Vozidla under Kniha jízd, Uživatelé under Systém (`navData.tsx:226,297,448,470`). Salient consequence: issued orders (Administrativa) pull suppliers from `sklad_suppliers` (Sklad), so fixing a supplier means jumping to Sklad. **Fix:** at minimum add cross-links (e.g. "spravovat dodavatele" from the issued-order supplier picker → `/warehouse/suppliers`).
+
+- **Sklad nav is a flat 10-item list mixing daily ops with one-time config.** Ten ungrouped items (`navData.tsx:314-463`) intermix `warehouse.operate` daily drivers with rarely-touched `warehouse.manage` config (Kategorie/Lokace/Dodavatelé). **Fix:** split into operations vs "nastavení skladu" subgroups (or move the three config screens behind one entry).
+
+- **One "Vytvořit objednávku" button navigates to a page on one tab and opens a modal on the other.** On Objednávky: Vydané routes to `/orders/issued/new`, Přijaté opens a modal (`Orders.tsx:119-132`, `ReceivedOrders.tsx:606`). Across modules, offers/invoices/issued orders use routed full-page forms while received orders create in a modal. **Fix:** pick one pattern per tier or split into two distinct labelled actions.
+
+- **No skip-to-content link — keyboard users tab the whole sidebar on every page.** A permanent 248px sidebar with many links renders before `<main>` (`AppShell.tsx:130-145,210-223`), with no skip link and no id on `<main>`. **Fix:** add a visually-hidden "Přeskočit na obsah" link (visible on focus) targeting `id="main-content"`.
+
+### 4.9 Discoverability & workflow friction
+
+- **"Moje žádosti" has no create action.** Its header has no actions and its empty state literally instructs filing on the Docházka page (`LeaveRequests.tsx:241,254`); the only way to open the leave form is a button buried on the punch screen (`Attendance.tsx:936,978`). **Fix:** add a "Nová žádost" button to `LeaveRequests` opening the same modal; lift the modal into a shared component.
+
+- **Dashboard "Vaše dnešní zařazení" card shows the project as plain text — every other dash card links onward.** `DashTodayPlan` renders `projectLabel` as plain text (`:69`) while other cards link "Vše →"/"Detail →." **Fix:** wrap `projectLabel` in a `RouterLink` to `/projects/:id` (id is already in `TodayPlan`); optionally add a "Plán prací →" header button.
+
+- **Issue detail shows the consumed reservation as a raw "ID: n" database identifier** (`WarehouseIssueDetail.tsx:204`), unlike the project reference beside it (a real link). **Fix:** at minimum render "R{id}" to match `ReservationPicker`'s own label (`:65`).
+
+- **`ReservationPicker` is dead code — a manual Výdejka can't draw down an existing reservation.** A ready-made picker exists (`ReservationPicker.tsx:14`) but is imported nowhere; the issue form only sets `reservation_id` from router prefill (`WarehouseIssueForm.tsx:183`). **Fix:** render it in the issue-form line (gated on item_id+project_id, mirroring `BatchSelect`) — or delete the unused component.
+
+- **Audit log surfaces only the one-line description — the stored old/new values are on the wire but never shown.** `audit_logs` stores `old_values`/`new_values` and the route returns full rows (`routes/admin/audit-log.ts:64-74`), but the page's row type omits them and rows aren't expandable (`AuditLog.tsx:97-105,229-275`). The most valuable part of an audit trail is invisible. **Fix:** add the fields to the type and open a detail modal rendering old→new.
+
+- **Odin's empty state never hints it can query real system data.** The landing hero only says "Zeptejte se na cokoli, nebo přiložte fakturu…" (`OdinThread.tsx:82-149`), giving no hint Odin can query invoices/offers/orders/projects/warehouse via its read-only tools. **Fix:** add 3-4 clickable example-prompt chips that prefill the composer (`OdinChat.tsx:218-219`).
+
+- **Keyboard shortcuts ship undiscoverable; `ShortcutsHelp` is a permanent no-op.** `ShortcutsHelp` is mounted but returns null (`:1-7`, `AppShell.tsx:226`), while Ctrl+Enter (note save), Enter (Odin send), Enter (plan category) ship with no help. **Fix:** build the "?"-opens-cheat-sheet overlay, or as a cheap first step add `title` hints (copy `OdinComposer`'s `title="Odeslat (Enter)"` onto `NoteCard`'s Ctrl+Enter).
+
+- **Plan grid resets to the current week on every remount.** `usePlanWork` inits view/anchor to `new Date()` with no persistence (`:112-113`), so leaving and returning to `/plan` loses your scroll position. **Fix:** persist view+anchor (URL query or localStorage).
+
+- **"Zpět na správu" / post-save links pass `?month=YYYY-MM` but AttendanceAdmin ignores it.** `AttendanceCreate` (`:141`) and `AttendanceLocation` (`:211`) link to `/attendance/admin?month=…`, but `useAttendanceAdmin` never reads the URL (hard-inits month to current). **Fix:** seed the initial month from `useSearchParams()` and keep it synced.
+
+- **Receipt/Issue details never show a document-level total.** They compute per-line "Celkem" but the `DataTable` has no footer/sum (`WarehouseReceiptDetail.tsx:250`, `WarehouseIssueDetail.tsx:182`); forms show no running total. Every other money-bearing document leads with a prominent total. **Fix:** add a summary line (sum of qty×unit_price via `formatCurrency`) under the Položky table and a live running total in the forms.
+
+- **Inventory form only creates a draft; Receipt/Issue forms offer "Uložit a potvrdit" in one action.** `WarehouseInventoryForm` offers only "Vytvořit inventuru" (`:204`); to post you must go to the detail and click "Potvrdit inventuru" (`:209`). **Fix:** add a "Vytvořit a potvrdit" button (the form already collects `actual_qty`), OR surface a hint explaining the deliberate two-step variance-review flow.
+
+- **Trips admin can't enter a trip on behalf of a driver, though attendance admin can create for any employee.** `TripsAdmin` offers only Tisk + a Vozidla link (`:710`), no "add trip," and its edit modal has no driver picker. The `/trips` POST already accepts `body.user_id` (`trips.ts:341`). **Fix:** add an "Přidat jízdu" action with a driver selector, mirroring `AttendanceAdmin`.
+
+- **⚠ Found during verification (backend, not UX): `POST /trips` accepts `body.user_id` without a `trips.manage` check.** Any user holding only `trips.record` can create a trip attributed to another user's id (`src/routes/admin/trips.ts:341`, `trips.schema.ts:13`) — reads are correctly scoped (`buildTripsWhere` limits non-managers to their own trips) but the create path is not. Minor impersonation-on-create authz gap. **Fix:** ignore `body.user_id` (force `authData.userId`) unless the caller holds `trips.manage`.
+
+- **Personal Trips "Záznam" shows company-wide trips/stats for managers.** Unlike "Moje historie" (filters by `userId`), the personal Trips page calls `tripListOptions`/`tripStatsOptions` with no `userId` and renders a "Řidič" column (`Trips.tsx:166,359`) — surfacing all drivers' trips and company-wide totals, unlike the strictly-personal attendance punch screen. **Fix:** pass `userId` (matching `TripsHistory`), or relabel/drop the Řidič column. Keep list and stats on one scope.
+
+### 4.10 Forked/duplicated shared modules & code drift
+
+- **`InvoiceDetail` forks the shared document editor (and drops the item-description maxLength cap).** Offers/issued orders compose shared `DocumentItemsEditor`/`useDocumentPdf`/`useUnsavedChangesGuard`; `InvoiceDetail` reimplements all three (`:241-541,1175-1196,942-958`). Divergence: the invoice item description textarea has **no maxLength** while the shared editor caps it (`DocumentItemsEditor.tsx:390`) — an over-long description 500s at Prisma instead of capping client-side. **Fix:** add a `showVat`/`vatOptions` flag to `DocumentItemsEditor` (respecting "VAT only on invoices") and migrate `InvoiceDetail` onto it plus the shared hooks.
+
+- **Status label/color maps duplicated across warehouse, projects and leave.** `documentStatus.ts` exists specifically to kill per-page maps, yet DRAFT/CONFIRMED/CANCELLED recur across 6 warehouse files (`WarehouseIssues.tsx:35-48`), `Projects.tsx:44-57`/`ProjectDetail.tsx:37-50` are byte-identical, and `LeaveRequests.tsx:25-55`/`LeaveApproval.tsx:36-66` are byte-identical. **Fix:** add `WAREHOUSE_DOC_STATUS`, `MOVEMENT_TYPE`, `RESERVATION_STATUS`, `PROJECT_STATUS`, `LEAVE_STATUS`/`LEAVE_TYPE` to `documentStatus.ts` and import them.
+
+- **`AttendanceAdmin` fetches outside React Query (raw `apiFetch` in `useEffect` + manual refetch dance).** `useAttendanceAdmin` loads projects/users/records via raw `apiFetch` with its own `setData`/`setLoading` (`:823,871`), so it doesn't participate in `['attendance']` invalidations — each mutation must invalidate AND manually re-run `fetchData` with a `setTimeout(300)` (`:1057-1063`). The single biggest structural inconsistency and a latent stale-data risk. **Fix:** migrate reads to React Query options.
+
+- **Orphaned standalone attendance-create page diverges from the admin modal (no project logs).** Adding a record exists twice: a standalone full-page form at `/attendance/create` AND `ShiftFormModal` (`AttendanceAdmin.tsx:194`). The modal supports per-shift project-time logs; the standalone page can't (`AttendanceCreate.tsx:63-147`), and nothing navigates to it. **Fix:** delete `AttendanceCreate.tsx` and its route — the modal is the live superset.
+
+- **"Vytvořit objednávku" modal uses two different file pickers.** The Offers-list version uses the shared `FileUpload`; the Offer-detail version reimplements it with a raw `<input type=file>` + manual readout + custom remove button (`OfferDetail.tsx:1066-1112` vs `Offers.tsx:894-929`). Same dialog, two attachment UIs. **Fix:** replace the raw input with `FileUpload` (gains drag-drop/validation).
+
+- **Warehouse entities use three different create/edit interaction models.** Items edit inline on the detail page via a toggle (`WarehouseItemDetail.tsx:112`); Receipts/Issues use a full-page Form + read-only Detail; Inventory has a Form for creation only; Reservations/Categories/Locations/Suppliers use a list-page Modal. Items (a flat record like Suppliers) using inline edit is the main outlier. **Fix:** document one convention (line-item records = Form+Detail; flat lookups = list modal) and reconcile the Items outlier — treat as a documented rule, not a forced risky migration.
+
+- **Inconsistent "record not found": Item detail redirects away, siblings keep a stable URL.** `WarehouseItemDetail` toasts + `navigate('/warehouse/items')` (`:153-158`); `WarehouseIssueDetail`/`ReceiptDetail`/`InventoryDetail` render an in-place "nebyla nalezena" EmptyState with a Back button and keep the URL (`:122`/`:200`/`:99`). **Fix:** align Item detail to the in-place EmptyState pattern.
+
+- **Settings save model is inconsistent.** The System tab has **two** "Uložit" buttons doing the same thing (`Settings.tsx:997-1007,1193-1199`); other cards have no save; 2FA saves instantly; on Firma, bank accounts/logo apply instantly while company info/numbering/currency need the bottom save (`CompanySettings.tsx:990-1013,1457-1461`). The user can't predict whether a change is live or pending. **Fix:** drop one duplicate System Save; visually distinguish auto-apply vs pending controls.
+
+- **Attendance location page formats datetime with `new Date()` instead of the timezone-safe shared helper.** `AttendanceLocation` defines a local `formatDatetimeLocal` parsing with `new Date()` (`:176`); the rest of attendance uses the timezone-safe `formatDatetime` (`attendanceHelpers.ts:42`), so the same timestamp renders differently. **Fix:** build a regex-based timezone-safe formatter that keeps the year (the location detail legitimately wants the year, which `formatDatetime` omits).
+
+- **Document editor uses two reorder gestures side by side.** Line items reorder via a drag handle (`DocumentItemsEditor.tsx:350-364`), but sections (`SectionsEditor.tsx:200-219`) and company custom fields (`CompanySettings.tsx:1049-1067`) use up/down arrows — on the same page. The drag-only items are also less keyboard-discoverable. **Fix:** add up/down arrow buttons alongside the line-item drag handle (matching SectionsEditor) — also fixes the keyboard-affordance gap.
+
+- **Login re-implements the theme toggle.** The shell uses shared `<ThemeToggle/>` (animated crossfade, title + aria-label); Login builds its own IconButton with hand-duplicated SVGs, only a title, no aria-label, no animation (`Login.tsx:264-313` vs `ThemeToggle.tsx:36-57`). The first screen every user sees is less accessible. **Fix:** reuse the shared `<ThemeToggle/>`.
+
+### 4.11 Visual & theming consistency
+
+- **Projects status-chip colors diverge from the app-wide convention (and duplicate the label map).** `documentStatus.ts` establishes success=done/paid, error=cancelled, info=open. Projects breaks all three — ACTIVE=green, COMPLETED=**blue**, CANCELLED=**grey** (`Projects.tsx:50`, `ProjectDetail.tsx:43`). So a finished project shows blue while a finished order shows green. **Fix:** add a `PROJECT_STATUS` map (aktivni→info, dokonceny→success, zruseny→error) and consume via `statusLabel`/`statusColor`.
+
+- **Linked order status on Project detail renders as a raw untranslated token.** `ProjectDetail` shows `STATUS_LABELS[project.order_status]` but `STATUS_LABELS` is the _project_ map while `order_status` is `prijata`/`v_realizaci`/… — zero key overlap (`:577`), so a completed order shows "(dokoncena)" lowercase plain text. **Fix:** render via `statusLabel(ORDER_STATUS, project.order_status)` (ideally a `StatusChip`).
+
+- **Settings admin-role callout uses a solid `info.light`/`info.dark` fill (the forbidden .light-fill anti-pattern).** The "Administrátor má vždy plný přístup" box is hand-styled with `bgcolor:'info.light'`/`color:'info.dark'` (`Settings.tsx:1228-1229`) — the single solid palette-.light fill in the admin, violating the documented channel-alpha rule; in dark mode it's garish low-contrast blue-on-blue. **Fix:** use the kit `<Alert severity='info'>` (`Alert.tsx:8`), or a channel-alpha wash.
+
+- **Dashboard "Vystavit fakturu" quick action reuses the destructive error/red palette.** `DashQuickActions` sets color `'danger'` → MUI error (`:296`,`:59`), the same red as every Delete button, so "Issue invoice" reads as destructive beside green/blue/orange create actions. _(Caveat: red is also the invoice PDF brand family (#de3a3a), and "Odchod" uses `danger` too — this may be deliberate branding; treat as optional.)_ **Fix:** if not intentional, change to a non-destructive color (info/primary); reserve error/red for deletes.
+
+- **Plan `DayInRangeModal` shows raw ISO dates while the rest of the plan dialogs format cs-CZ.** It prints "2026-06-28 – 2026-07-02" (`PlanCellModal.tsx:466,474,495`) while ViewModal/DayPanel format "28. 6. 2026." **Fix:** wrap the dates in `formatDate()`.
+
+- **Project delete confirm differs between list and detail.** The list ConfirmDialog always renders the "Smazat i soubory na disku" checkbox even for projects with no NAS folder, with terse copy, no name, no irreversibility warning (`Projects.tsx:508,516`); the detail gates the checkbox on `has_nas_folder` and uses richer copy + "Tato akce je nevratná." (`ProjectDetail.tsx:621,626`). **Fix:** gate the list checkbox on `has_nas_folder` and use the same copy (name + warning).
+
+### 4.12 Microcopy & localization
+
+- **Goods-receipt module named four ways; "Příjmy" also reads as financial income.** Nav "Příjmy" (`navData.tsx:348`), overview button "Nový příjem" (`Warehouse.tsx:203`), list title "Příjmové doklady" + "Nový doklad" (`WarehouseReceipts.tsx:170,178`), detail/audit "Příjemka" (`WarehouseReceiptDetail.tsx:204`, `entityTypeLabels.ts:29`). Issues mirror this (Výdeje/Výdejky/Výdejka). "Příjmy" is the standard Czech word for _income_, so the nav label is actively misleading. **Fix:** settle on "Příjemka"/"Výdejka" everywhere.
+
+- **Saving/busy labels inconsistent; one "Chyba pripojeni" diacritics typo; Modal overrides caller `submitText` mid-save.** Competing forms: "Ukládám…" (Modal, AttendanceCreate, NoteCard, DashProfile), "Ukládání..." (most pages), "Zpracovávám…" vs "Zpracovávám...", plus "Vytváření..."/"Odesílám..."; ellipsis sometimes "…" sometimes three dots. The connection-error fallback is "Chyba pripojeni" (no diacritics) on the dashboard (`Dashboard.tsx:127`, `AuthContext.tsx:256,314`) vs "Chyba připojení" elsewhere. Modal hardcodes `loading?'Ukládám…':submitText` (`:96`), overriding "Vytvořit uživatele" mid-save. **Fix:** fix the typo (outlier vs ~90 sites); standardize the busy label + Unicode ellipsis; the Modal hardcoding is acceptable for save forms (lower priority).
+
+- **"Cancelled" order status spelled two ways in `documentStatus.ts`.** Received orders use `stornovana`→"Stornována" (`:49`); issued orders use `cancelled`→"Stornovaná" (`:58`) — side-by-side under the same `/orders` page. These are display labels (safe to change). **Fix:** pick one Czech form for both.
+
+- **Add-line button uses literal "+ Přidat položku" in document editors vs icon + "Přidat položku" in warehouse forms.** `DocumentItemsEditor.tsx:596` (literal plus, no startIcon) vs warehouse forms with `startIcon={PlusIcon}` (`WarehouseIssueForm.tsx:601` etc.). **Fix:** standardize the affordance and label.
+
+- **Create/edit modal submit labels mix entity-specific, bare, and default wording.** "Vytvořit zákazníka"/"Uložit změny" (`OffersCustomers.tsx:543`), "Vytvořit uživatele" (`Users.tsx:369`), bare "Vytvořit"/"Uložit" (`OffersTemplates.tsx:361`), and Vehicles falls back to the Modal default "Uložit" (`Modal.tsx:36`). **Fix:** adopt one rule (create="Vytvořit", edit="Uložit změny") and set it as the Modal default.
+
+- **Create-action verb differs across analogous list pages; both Orders tabs share the identical "Vytvořit objednávku" label.** Imperative "Přidat X" (master data) vs "Nový/Nová X" (documents) vs "Vytvořit objednávku" (Orders, identical on both tabs for two different doc types, `Orders.tsx:125,129`); the empty-state CTA verb mirrors and compounds this. **Fix:** disambiguate the two Orders tabs first ("Nová vydaná/přijatá objednávka"), then pick one verb convention and align the empty-state CTA.
+
+- **Several numbers/prices bypass cs-CZ formatting; file-size unit casing disagrees (kB vs KB).** Offers item-template price uses `Number().toFixed(2)`→"1234.50" (period, no separator/currency, `OffersTemplates.tsx:287`); warehouse batch picker builds "…toFixed(2) Kč" (`WarehouseIssueForm.tsx:160`); vacation/sick hour balances use `.toFixed(1)`→"12.5" (`AttendanceBalances.tsx:307`); zeros render "0 Kč" vs "0,00 Kč." File-size helper duplicated with "kB" (`FileUpload.tsx:9`) vs "KB" (`OfferDetail.tsx:1072`). **Fix:** route money through `formatCurrency` and decimals through cs-CZ/Intl; extract one `formatFileSize()` with one unit casing.
+
+- **Leave-request modal day/hour estimate ignores public holidays.** The modal previews "X pracovních dnů" using `calculateBusinessDays` (Mon–Fri only, `Attendance.tsx:498,1242`), but the rest of the system is holiday-aware (server `leave-requests.ts:99` excludes weekends AND holidays). A vacation spanning e.g. 1 May over-counts vs the stored `total_days`/`total_hours`. **Fix:** make the modal estimate holiday-aware (reuse the holiday helper).
+
+### 4.13 Mobile / responsive
+
+- **Status-filter tab bars clip on phones — shared `Tabs` has no scrollable variant.** `Tabs.tsx:28-49` uses MUI's default `variant="standard"` (overflow hidden, no scroll). At ~360px the 5 offer/invoice tabs and 4 project tabs overflow the centered Box and get clipped with no scroll affordance — effectively unreachable. **Fix:** set `variant="scrollable"`, `scrollButtons="auto"`, `allowScrollButtonsMobile` — one change fixes every status filter and the issued/received toggle.
+
+- **Shared Modal never goes full-screen on phones; leave date grid is hardcoded two-column.** `Modal` renders a plain `fullWidth+maxWidth` Dialog with no responsive `fullScreen` (`:67-75`), so the ~9-field Trip form, the admin shift form and the leave form become a narrow scrolling box at 360px. The leave modal's Od/Do grid is hardcoded `minmax(0,1fr) minmax(0,1fr)` (`Attendance.tsx:1195-1199`) while every other date-pair grid is responsive `{xs:'1fr',sm:'1fr 1fr'}` (`ShiftFormModal.tsx:254`, `Trips.tsx:528-535`). **Fix:** add `fullScreen={useMediaQuery(down('sm'))}` to Modal; fix the leave grid.
+
+- **Long full-page editors keep Save only in the top header (no sticky save); placement differs page-to-page.** Document detail editors place all Save/Create/Activate in the top `headerActionsSx` slot (`OfferDetail.tsx:688-828`), so after scrolling through header fields/picker/line-items/rich-text/notes a phone user must scroll back to the top to save. `AttendanceCreate` pins Zrušit/Uložit at the **bottom** (`:362-374`); modals pin submit in DialogActions — three placements. **Fix:** add a sticky action bar to long editors and standardize placement.
+
+- **Warehouse issue/receipt line items lack the labeled card-per-row mobile layout the document editor has.** `DocumentItemsEditor` has a dedicated `isMobile` branch — a bordered card per row with "Položka N" index, labeled fields, per-row total, drag/remove (`:170-342`). `WarehouseIssueForm.tsx:513-567` just collapses a grid to `xs:'1fr'` with placeholder-only fields, no border/labels/separator — once a value is typed the placeholder vanishes and rows blur together. Worst exactly where shop-floor mobile use is likely. **Fix:** reuse the card-per-row pattern (ideally a shared mobile line-item card).
+
+- **FilterBar children mix fixed-vs-grow flex bases, leaving dead space on mobile.** `AttendanceAdmin.tsx:202,205` use `flex:'0 0 180px'`/`'0 0 220px'` and `AttendanceHistory.tsx:516` uses `flex:'0 0 180px'` (fixed, never grow), so on a phone they sit narrow with dead space beside them, while `Offers.tsx:786` uses `flex:'1 1 320px'` which fills the row. **Fix:** adopt one convention (e.g. `flex:'1 1 <min>px'`) or have `FilterBar` stretch children full-width below `sm`.
+
+### 4.14 Accessibility
+
+- **Desktop document line-item grid inputs are unlabeled while the mobile card layout labels every field.** The mobile branch passes explicit labels (Popis, Množství, Jednotka, Jedn. cena, Sleva %); the desktop table renders the same TextFields with **no** label/aria-label, relying on visual `<th>` headers not programmatically associated with the inputs; the desktop "V ceně" Checkbox is unnamed (`DocumentItemsEditor.tsx:374-440,445-450`). A screen-reader user editing an offer on desktop hears a column of unlabeled "edit text" boxes. **Fix:** add an `aria-label` to each desktop cell control (e.g. `Množství, položka ${index+1}`).
+
+- **List-page search boxes are placeholder-only inputs with no accessible name.** Raw TextFields with only a placeholder (not an accessible name) across ~13 pages (`Offers.tsx:787`, `Invoices.tsx:741`, `WarehouseItems.tsx:180`, `Projects.tsx:454`, `IssuedOrders.tsx:386`). **Fix:** add `aria-label="Hledat"` + `type="search"` — best via a shared `SearchField` (also adds the native clear button and mobile search keyboard).
+
+- **(Cross-listed) DataTable clickable rows aren't keyboard-operable; no skip-to-content link.** See §4.7 (row semantics) and §4.8 (skip link).
+
+### 4.15 Performance & bundle
+
+- **MUI + Emotion live in the 781 kB entry chunk, so every deploy busts the cached UI vendor code.** `vite.config.ts` `manualChunks` only carves out react/react-dom/react-router (436 kB) and framer-motion (147 kB); the entire MUI library + Emotion fall into the entry chunk (781 kB raw / 232 kB gzip). With frequent same-day patch releases, daily users re-download ~232 kB gzip of unchanged MUI every deploy. **Fix:** split `@mui/*`+`@emotion/*`(+quill) into a long-lived `vendor-mui` chunk.
+
+- **framer-motion (147 kB) is a static dependency of the eager AppShell, loading on first paint incl. Login.** `AppShell`/`PageEnter`/`ThemeToggle` statically import framer-motion (`PageHeader` deliberately does not); `AppShell` is eagerly imported by `AdminApp` (`:8`, `AppShell.tsx:101`). Login pays for it too. **Fix:** migrate to `LazyMotion` + the lightweight `m` component (`domAnimation`) — note Login and the Dash\* components import framer-motion directly, so lazy-gating only `PageEnter` won't remove it from the login critical path.
+
+- **Dashboard + its 7 Dash\* subcomponents are bundled into the entry chunk, downloaded on the Login screen.** Dashboard and Login are statically imported in `AdminApp` (`:14-15`), so an unauthenticated user hitting `/login` downloads the entire authenticated dashboard's code before typing a password. **Fix:** lazy-load Dashboard via `lazyWithReload` like every other route; keep Login eager.
+
+- **No route-transition progress indicator and no link prefetch — heavy pages blank to a spinner on click.** Clicking a sidebar item blanks main content to a centered spinner while the chunk downloads (PlanWork 44 kB, InvoiceDetail 35 kB, AttendanceLocation 155 kB with Leaflet), with no top progress bar and no prefetch (zero `prefetchQuery`/`onMouseEnter`/`preload` hits). A `ProgressBar` exists but is reused only as an attendance-fund meter. **Fix:** add an unobtrusive top `LinearProgress` during route transitions and prefetch the lazy chunk (+ primary query) on sidebar link hover/focus.
+

+
+## 5. Suggested Sequencing
+
+**Sprint 1 — "Stop lying to the user" (mostly Quick Wins, ~2-3 days).**
+Ship the data-freshness convergence (one invalidation set per family), the global `QueryCache.onError` so failed fetches stop showing as empty, the scrollable mobile tabs, the invoice-paid confirm, the silent-toggle `onError` toasts, the draft-PDF 404 gate, the wrong-Orders-tab redirect, the search debounces, the `csCZ` localeText, the `document.title`, the project/order status-color fixes, and the diacritics/label typos. These are individually small, collectively high-trust, and low-risk. Pair each with a quick Playwright check on the dev server (the user runs it).
+
+**Sprint 2 — "Converge the primitives" (the structural anti-drift work, ~1 week).**
+De-fork the dirty-guards and add them to the six unguarded editors; route the invoice PDF openers through `useDocumentPdf`; consolidate the status maps into `documentStatus.ts`; standardize validation on inline `<Field error>` (starting with the mirrored screens); add `<form onSubmit>` to Modal; migrate hand-rolled headers to `PageHeader`; replace inline English errors with `apiErrorMessage`. This is where you stop the Sprint-1 fixes from re-drifting, and it's the cleanest fit for the codebase's "extend, never fork" rule.
+
+**Sprint 3 — "Mobile + a11y + warehouse parity" (~1 week).**
+Full-screen modals, sticky save bars, warehouse card-per-row line items, keyboard-operable rows, skip link, search-field accessible names, warehouse document totals, the leave "Nová žádost" action, and the warehouse "Potvrdit" confirm.
+
+**Strategic backlog (schedule deliberately, each is multi-day and one needs a migration).**
+Invoice edit-locking (DB migration + route trio — coordinate the migration per CLAUDE.md: ask the user to stop the dev server, apply to `app_test` too). The router upgrade for in-app dirty-nav blocking. `AttendanceAdmin` onto React Query. `InvoiceDetail` onto the shared editor. Real skeletons. Bundle splitting + route prefetch. Treat the navigation/IA items (breadcrumbs, master-data nav grouping, `/customers` move) as a focused IA pass once the above settle.
+
+A note on scope discipline: nearly every item here is "make B match the already-correct A," so the safest pattern is to **read the reference implementation first** (offers/issued orders for documents, `WarehouseSuppliers` for lists, `documentStatus.ts` for status) and converge onto it — rather than inventing new patterns. That keeps the diff small and the regression surface low, which matches the user's same-day-patch-release rhythm.

+# Per-document custom-field print selection — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Let each offer, issued order, and invoice choose — on its detail page — which company custom fields print in its PDF sender block; default none selected.
+
+**Architecture:** A new nullable `selected_custom_fields` column (JSON-array-in-VARCHAR) on `quotations`, `issued_orders`, `invoices`. A shared backend util encodes/decodes the index array. Create/update services persist it; detail services decode it to `number[]`. The PDF `buildAddressLines()` company-block builder gains an optional selected-indices filter. A shared React picker reused by the three detail pages drives the selection.
+
+**Tech Stack:** Prisma 7 / MySQL, Fastify 5, Zod 4, Vitest (real `app_test` DB), React 19 + MUI v7 + React Query.
+
+**Spec:** `docs/superpowers/specs/2026-06-16-per-document-custom-field-selection-design.md`
+
+---
+
+## Conventions for this plan
+
+- This shell is non-interactive — `prisma migrate dev` is forbidden. Use the `migrate diff` recipe (Task 1).
+- **Before the migration, ask the user to stop their dev server and wait for confirmation** (it holds DB connections). Do not run the migration until they confirm.
+- Server tests run against `app_test` via `.env.test` (`npm test`). Apply the migration to `app_test` too or the suite breaks.
+- `npm run typecheck` = `tsc -b --noEmit`. `npm run lint` must stay at 0 errors.
+- Selection semantics in `buildAddressLines`: param **omitted/`undefined`** ⇒ show ALL custom fields (unchanged behavior — used for customer/supplier blocks). Param is an **array** (possibly empty) ⇒ show ONLY those indices (used for the company/sender block; empty ⇒ none).
+
+---
+
+## File Structure
+
+- **Modify** `prisma/schema.prisma` — add `selected_custom_fields String?` to `quotations`, `issued_orders`, `invoices`.
+- **Create** `prisma/migrations/<ts>_add_selected_custom_fields/migration.sql`.
+- **Modify** `src/utils/custom-fields.ts` — add `encodeSelectedCustomFields` / `parseSelectedCustomFields`.
+- **Create** `src/__tests__/selected-custom-fields.test.ts` — util + integration coverage.
+- **Modify** `src/schemas/offers.schema.ts`, `issued-orders.schema.ts`, `invoices.schema.ts` — new optional array field.
+- **Modify** `src/services/offers.service.ts`, `issued-orders.service.ts`, `invoices.service.ts` — persist on create/update, decode in detail.
+- **Modify** `src/routes/admin/offers-pdf.ts`, `issued-orders-pdf.ts`, `invoices-pdf.ts` — filter company custom lines.
+- **Modify** `src/admin/lib/queries/offers.ts`, `issued-orders.ts`, `invoices.ts` — add `selected_custom_fields: number[]` to detail interfaces.
+- **Create** `src/admin/components/document/CustomFieldsPrintPicker.tsx` — shared picker.
+- **Modify** `src/admin/pages/OfferDetail.tsx`, `IssuedOrderDetail.tsx`, `InvoiceDetail.tsx` — render picker, wire into save payload.

+
+## Task 1: Schema column + migration
+
+**Files:**
+
+- Modify: `prisma/schema.prisma` (models `quotations`, `issued_orders`, `invoices`)
+- Create: `prisma/migrations/<yyyyMMddHHmmss>_add_selected_custom_fields/migration.sql`
+
+- [ ] **Step 1: Ask the user to stop their dev server**
+
+Post: "Please stop your dev server so I can apply a migration, and tell me when it's stopped." Wait for confirmation before any later `migrate deploy` step.
+
+- [ ] **Step 2: Add the column to each model in `prisma/schema.prisma`**
+
+Add this line to the `quotations` model (near other scalar columns, e.g. after `language`):
+
+```prisma
+  selected_custom_fields String? @db.VarChar(255)
+```
+
+Add the identical line to the `issued_orders` model and to the `invoices` model.
+
+- [ ] **Step 3: Generate the migration SQL**
+
+Run (Git Bash):
+
+```bash
+cd /d/cortex/boha-app-ts
+TS=$(date +%Y%m%d%H%M%S)
+mkdir -p "prisma/migrations/${TS}_add_selected_custom_fields"
+npx prisma migrate diff --from-config-datasource --to-schema prisma/schema.prisma --script \
+  > "prisma/migrations/${TS}_add_selected_custom_fields/migration.sql"
+```
+
+Expected: a `migration.sql` containing three `ALTER TABLE … ADD COLUMN selected_custom_fields VARCHAR(255) NULL` statements (one per table). Open it and confirm it touches ONLY `quotations`, `issued_orders`, `invoices` and adds nothing else (no BOM — if it was written via PowerShell, strip the BOM).
+
+- [ ] **Step 4: Apply to dev DB + regenerate client (after user confirmed server stopped)**
+
+```bash
+npx prisma migrate deploy
+npx prisma generate
+```
+
+Expected: "All migrations have been applied" and a regenerated client.
+
+- [ ] **Step 5: Apply to the test DB**
+
+```bash
+DATABASE_URL="$(grep -m1 '^DATABASE_URL' .env.test | cut -d= -f2- | tr -d '"')" npx prisma migrate deploy
+```
+
+Expected: the same migration applied to `app_test`. (If the env parsing is awkward on this shell, temporarily set `DATABASE_URL` to the app_test URL from `.env.test` and run `npx prisma migrate deploy`.)
+
+- [ ] **Step 6: Typecheck**
+
+Run: `npm run typecheck`
+Expected: PASS (the new Prisma field is now known to the client).
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add prisma/schema.prisma prisma/migrations
+git commit -m "feat(documents): add selected_custom_fields column to quotations/issued_orders/invoices"
+```

+
+## Task 2: Backend encode/decode util (TDD)
+
+**Files:**
+
+- Modify: `src/utils/custom-fields.ts`
+- Test: `src/__tests__/selected-custom-fields.test.ts`
+
+- [ ] **Step 1: Write the failing test**
+
+Create `src/__tests__/selected-custom-fields.test.ts`:
+
+```ts
+import { describe, it, expect } from "vitest";
+import {
+  encodeSelectedCustomFields,
+  parseSelectedCustomFields,

+    expect(encodeSelectedCustomFields([])).toBeNull();

+  });
+
+  it("dedupes, sorts, and drops invalid entries before encoding", () => {

+  });
+});
+```
+
+- [ ] **Step 2: Run it to confirm failure**
+
+Run: `npm test -- selected-custom-fields`
+Expected: FAIL — `encodeSelectedCustomFields is not a function`.
+
+- [ ] **Step 3: Implement the helpers**
+
+Append to `src/utils/custom-fields.ts`:
+
+```ts
+/**
+ * Per-document selection of which COMPANY custom fields print on a PDF.
+ * Stored positionally (matching the `custom_<i>` keys the PDF builder emits)
+ * as a JSON array string, e.g. "[0,2]". Null/empty means "none selected".
+ */
+export function encodeSelectedCustomFields(indices: unknown): string | null {
+  const clean = normalizeIndices(indices);
+  return clean.length > 0 ? JSON.stringify(clean) : null;
+}
+
+/** Decode the stored selection (string OR defensive array) into a clean number[]. */
+export function parseSelectedCustomFields(raw: unknown): number[] {
+  if (raw == null) return [];
+  if (Array.isArray(raw)) return normalizeIndices(raw);
+  if (typeof raw !== "string" || raw.trim() === "") return [];
+  try {
+    return normalizeIndices(JSON.parse(raw));
+  } catch {
+    // Malformed JSON in a selection column degrades to "none" (expected
+    // condition — a hand-edited/legacy row should never 500 a PDF render).
+    return [];
+  }
+}
+
+function normalizeIndices(input: unknown): number[] {
+  if (!Array.isArray(input)) return [];
+  const set = new Set<number>();
+  for (const v of input) {
+    if (typeof v === "number" && Number.isInteger(v) && v >= 0) set.add(v);
+  }
+  return [...set].sort((a, b) => a - b);
+}
+```
+
+- [ ] **Step 4: Run the test to confirm it passes**
+
+Run: `npm test -- selected-custom-fields`
+Expected: PASS (all util cases).
+
+- [ ] **Step 5: Commit**
+
+```bash

+## Task 3: Zod schemas
+
+**Files:**
+
+- Modify: `src/schemas/offers.schema.ts`
+- Modify: `src/schemas/issued-orders.schema.ts`
+- Modify: `src/schemas/invoices.schema.ts`
+
+- [ ] **Step 1: Offers schema**
+
+In `src/schemas/offers.schema.ts`, inside `CreateQuotationSchema`, add after the `sections` line (line 50):
+
+```ts
+  // Positional indices of company custom fields to print on this document's
+  // PDF. Omitted/empty ⇒ none. Update schema derives via .partial().
+  selected_custom_fields: z.array(z.number().int().nonnegative()).max(200).optional(),
+```
+
+(`UpdateQuotationSchema` already derives from this via `.partial().omit({ quotation_number: true })` — no change needed there.)
+
+- [ ] **Step 2: Issued-orders schema**
+
+In `src/schemas/issued-orders.schema.ts`, inside `CreateIssuedOrderSchema`, add after the `sections` field:
+
+```ts
+  selected_custom_fields: z.array(z.number().int().nonnegative()).max(200).optional(),
+```
+
+(`UpdateIssuedOrderSchema` derives via `.partial()` — no change.)
+
+- [ ] **Step 3: Invoices schema**
+
+In `src/schemas/invoices.schema.ts`, add the same line to BOTH `CreateInvoiceSchema` (after its `sections` field) and `UpdateInvoiceSchema` (after its `sections` field — invoices define the two schemas separately, so it must be added in both):
+
+```ts
+  selected_custom_fields: z.array(z.number().int().nonnegative()).max(200).optional(),
+```
+
+- [ ] **Step 4: Typecheck**
+
+Run: `npm run typecheck`
+Expected: PASS.

+- [ ] **Step 5: Commit**
+
+```bash

+
+**Files:**
+
+- Modify: `src/services/offers.service.ts`
+- Modify: `src/services/issued-orders.service.ts`
+- Modify: `src/services/invoices.service.ts`
+- Test: `src/__tests__/selected-custom-fields.test.ts` (extend)
+
+- [ ] **Step 1: Add the import to all three services**
+
+At the top of each of the three service files, add (or extend the existing import from `../utils/custom-fields`):
+
+```ts
+import {
+  encodeSelectedCustomFields,
+  parseSelectedCustomFields,
+} from "../utils/custom-fields";
+```
+
+- [ ] **Step 2: Offers — persist on create**
+
+In `createOffer` (`src/services/offers.service.ts`), inside `tx.quotations.create({ data: { … } })`, add after `scope_description`:
+
+```ts
+          selected_custom_fields: encodeSelectedCustomFields(
+            body.selected_custom_fields,
+          ),
+```
+
+- [ ] **Step 3: Offers — persist on update**
+
+In `updateOffer`, inside the `const data = { … }` object (after `scope_description`, before `modified_at`), add:
+
+```ts
+    selected_custom_fields:
+      body.selected_custom_fields !== undefined
+        ? encodeSelectedCustomFields(body.selected_custom_fields)
+        : undefined,
+```
+
+(`undefined` = "key absent in payload, leave column untouched" — matches the sibling header fields.)
+
+- [ ] **Step 4: Offers — decode in detail**
+
+In `getOffer`, in the returned object (after `valid_transitions`), add:
+
+```ts
+    selected_custom_fields: parseSelectedCustomFields(rest.selected_custom_fields),
+```
+
+- [ ] **Step 5: Issued orders — persist + decode**
+
+In `src/services/issued-orders.service.ts`:
+
+- In `createIssuedOrder`, inside `tx.issued_orders.create({ data: { … } })`, add:
+  ```ts
+          selected_custom_fields: encodeSelectedCustomFields(
+            body.selected_custom_fields,
+          ),
+  ```
+- In `updateIssuedOrder`, inside the header `data` object passed to `issued_orders.update`, add:
+  ```ts
+      selected_custom_fields:
+        body.selected_custom_fields !== undefined
+          ? encodeSelectedCustomFields(body.selected_custom_fields)
+          : undefined,
+  ```
+- In `getIssuedOrder`, in the returned object (after `valid_transitions`), add:
+
+  ```ts
+    selected_custom_fields: parseSelectedCustomFields(rest.selected_custom_fields),
+  ```
+
+- [ ] **Step 6: Invoices — persist + decode**
+
+In `src/services/invoices.service.ts`:
+
+- In `createInvoice`, inside `tx.invoices.create({ data: { … } })`, add after `internal_notes`:
+  ```ts
+        selected_custom_fields: encodeSelectedCustomFields(
+          body.selected_custom_fields,
+        ),
+  ```
+- In `updateInvoice`, inside the first `if (editable) { … }` block (after the `tax_date` handling, still inside the block), add:
+  ```ts
+  if (body.selected_custom_fields !== undefined)
+    data.selected_custom_fields = encodeSelectedCustomFields(
+      body.selected_custom_fields,
+    );
+  ```
+- In `getInvoice`, in the returned object (after `valid_transitions`), add:
+
+  ```ts
+    selected_custom_fields: parseSelectedCustomFields(rest.selected_custom_fields),
+  ```
+
+- [ ] **Step 7: Extend the test with an offers round-trip (real DB)**
+
+Append to `src/__tests__/selected-custom-fields.test.ts`. Match the existing suite's fixture style — import the offers service directly and clean up. Use a far-future placeholder where the suite does; if an existing offers test helper exists, prefer it. Minimal version:
+
+```ts
+import { createOffer, getOffer } from "../services/offers.service";
+import { prisma } from "../config/prisma"; // adjust to the project's prisma export path
+
+describe("offers selected_custom_fields round-trip", () => {
+  const created: number[] = [];
+  afterAll(async () => {
+    if (created.length)
+      await prisma.quotations.deleteMany({ where: { id: { in: created } } });
+  });
+
+  it("persists selection on create and decodes it on detail", async () => {
+    const res = (await createOffer({
+      status: "draft",
+      selected_custom_fields: [2, 0, 0],
+    })) as { id: number };
+    created.push(res.id);
+
+    const row = await prisma.quotations.findUnique({ where: { id: res.id } });
+    expect(row?.selected_custom_fields).toBe("[0,2]");
+
+    const detail = await getOffer(res.id);
+    expect(detail?.selected_custom_fields).toEqual([0, 2]);
+  });
+
+  it("stores null when selection is empty", async () => {
+    const res = (await createOffer({
+      status: "draft",
+      selected_custom_fields: [],
+    })) as { id: number };
+    created.push(res.id);
+    const row = await prisma.quotations.findUnique({ where: { id: res.id } });
+    expect(row?.selected_custom_fields).toBeNull();
+  });
+});
+```
+
+> Before running: confirm the prisma import path (`../config/prisma` vs `../config/db` — grep an existing test). Adjust the import to match.
+
+- [ ] **Step 8: Run tests**
+
+Run: `npm test -- selected-custom-fields`
+Expected: PASS (util + offers round-trip). If FK constraints require a customer, the `customer_id`-less draft path above avoids them.
+
+- [ ] **Step 9: Typecheck + commit**
+

+## Task 5: PDF rendering — filter company custom lines (TDD)
+
+**Files:**
+
+- Modify: `src/routes/admin/offers-pdf.ts`
+- Modify: `src/routes/admin/issued-orders-pdf.ts`
+- Modify: `src/routes/admin/invoices-pdf.ts`
+- Test: `src/__tests__/selected-custom-fields.test.ts` (extend, if a PDF render is unit-testable; otherwise assert via the helper — see Step 6)
+
+- [ ] **Step 1: Offers PDF — add the filter param to `buildAddressLines`**
+
+In `src/routes/admin/offers-pdf.ts`, change the signature (line 28-32):
+
+```ts
+function buildAddressLines(
+  entity: Record<string, unknown> | null,
+  isSupplier: boolean,
+  t: (key: string) => string,
+  selectedCustomFields?: number[],
+): AddressResult {
+```
+
+Then change the custom-field loop (lines 88-96) to skip non-selected indices when a selection array is provided:
+
+```ts
+const filterCustom = Array.isArray(selectedCustomFields);
+cfData.forEach((cf, i) => {
+  if (filterCustom && !selectedCustomFields!.includes(i)) return;
+  const cfName = (cf.name || "").trim();
+  const cfValue = (cf.value || "").trim();
+  const showLabel = cf.showLabel !== false;
+  if (cfValue) {
+    fieldMap[`custom_${i}`] =
+      showLabel && cfName ? `${cfName}: ${cfValue}` : cfValue;
+  }
+});
+```
+
+- [ ] **Step 2: Offers PDF — pass the document's selection into the COMPANY call**
+
+The offer's sender/company block is `supp` (`isSupplier: true` on `settings`). Update that call (lines 209-213) to pass the parsed selection; leave the customer call (`cust`) unchanged so customer custom fields still show in full:
+
+```ts
+const supp = buildAddressLines(
+  settings as unknown as Record<string, unknown>,
+  true,
+  t,
+  parseSelectedCustomFields(
+    (quotation as { selected_custom_fields?: unknown }).selected_custom_fields,
+  ),
+);
+```
+
+Add the import at the top of the file:
+
+```ts
+import { parseSelectedCustomFields } from "../../utils/custom-fields";
+```
+
+> Confirm `quotation` (the `OfferForPdf` payload the render function receives) is selected with the default field set so `selected_custom_fields` is present. It's a scalar column on `quotations`, so the default `findUnique`/`include` returns it — no `select` narrowing to adjust here.
+
+- [ ] **Step 3: Issued-orders PDF — same change on the COMPANY (buyer) block**
+
+In `src/routes/admin/issued-orders-pdf.ts`:
+
+- Add `selectedCustomFields?: number[]` as the last param of `buildAddressLines` and apply the identical `filterCustom` guard in its custom-field loop.
+- The company block is `buyer = buildAddressLines(settings, true, t)` (line 316). Change to:
+  ```ts
+  const buyer = buildAddressLines(
+    settings,
+    true,
+    t,
+    parseSelectedCustomFields(
+      (order as { selected_custom_fields?: unknown }).selected_custom_fields,
+    ),
+  );
+  ```
+- Leave `buildSupplierLines(...)` untouched (supplier fields keep showing in full).
+- Add `import { parseSelectedCustomFields } from "../../utils/custom-fields";`.
+
+> Confirm the render function's `order` param carries `selected_custom_fields`. If the route fetches the order via a narrow `select`, add `selected_custom_fields: true` to it; if it uses `include`/default scalars, it's already present. Grep the route's `issued_orders.findUnique`/`findFirst` before assuming.
+
+- [ ] **Step 4: Invoices PDF — same change on the COMPANY (supplier-of-invoice) block**
+
+In `src/routes/admin/invoices-pdf.ts`:
+
+- Add `selectedCustomFields?: number[]` as the last param of `buildAddressLines` and apply the identical `filterCustom` guard.
+- The company block is `supp = buildAddressLines(settings, true, t)` (line 457). Change to:
+  ```ts
+  const supp = buildAddressLines(
+    settings,
+    true,
+    t,
+    parseSelectedCustomFields(
+      (invoice as { selected_custom_fields?: unknown }).selected_custom_fields,
+    ),
+  );
+  ```
+- Leave `cust = buildAddressLines(customer, false, t)` untouched.
+- Note the separate `settings.custom_fields` read lower down (the "supplier email/web" extraction near line 469) is a DIFFERENT concern (pulls an email for a header line) — **do not** filter that; leave it as-is.
+- Add `import { parseSelectedCustomFields } from "../../utils/custom-fields";`.
+
+> Confirm `invoice` is fetched with default scalars (it is — `prisma.invoices.findUnique` without a narrowing `select` in this route), so `selected_custom_fields` is present.
+
+- [ ] **Step 5: Typecheck + lint**
+
+Run: `npm run typecheck && npm run lint`
+Expected: PASS, 0 lint errors.
+
+- [ ] **Step 6: Add a focused render assertion (extend the test file)**
+
+If the three PDF modules export their HTML render function (e.g. offers exports `renderOfferHtml`), add a test that renders with a stubbed settings object carrying two company custom fields and asserts only the selected one appears. Mock `html-to-pdf` per the suite convention; you're asserting on the returned HTML string, not a real PDF. Example for offers (adapt names to the actual export):
+
+```ts
+import { renderOfferHtml } from "../routes/admin/offers-pdf"; // confirm export name
+
+it("offer PDF prints only selected company custom fields", () => {
+  const settings = {
+    name: "Naše Firma s.r.o.",
+    custom_fields: JSON.stringify({
+      fields: [
+        { name: "Tel.", value: "123", showLabel: true },
+        { name: "Web", value: "example.cz", showLabel: true },
+      ],
+      field_order: [],
+    }),
+  };
+  const quotation = {
+    customers: null,
+    quotation_items: [],
+    scope_sections: [],
+    status: "draft",
+    currency: "CZK",
+    language: "cs",
+    selected_custom_fields: "[0]",
+  };
+  const html = renderOfferHtml(quotation as never, settings as never);
+  expect(html).toContain("Tel.: 123");
+  expect(html).not.toContain("example.cz");
+});
+```
+
+If the render function is NOT exported / not unit-testable without a DB, SKIP this step rather than forcing it — the util test (Task 2) plus the service round-trip (Task 4) already cover the data path; note in the commit that PDF filtering was verified manually. Do not export internals solely to test them if that breaks the module's encapsulation; prefer a manual verification note.

+## Task 6: Frontend — detail query types + shared picker
+
+**Files:**
+
+- Modify: `src/admin/lib/queries/offers.ts`, `issued-orders.ts`, `invoices.ts`
+- Create: `src/admin/components/document/CustomFieldsPrintPicker.tsx`
+
+- [ ] **Step 1: Add the field to the three detail interfaces**
+
+- `src/admin/lib/queries/offers.ts` — add to `OfferDetailData`:
+  ```ts
+  selected_custom_fields: number[];
+  ```
+- `src/admin/lib/queries/issued-orders.ts` — add to `IssuedOrderDetail`:
+  ```ts
+  selected_custom_fields: number[];
+  ```
+- `src/admin/lib/queries/invoices.ts` — add to `InvoiceDetail`:
+
+  ```ts
+  selected_custom_fields?: number[];
+  ```
+
+- [ ] **Step 2: Create the shared picker component**
+
+Create `src/admin/components/document/CustomFieldsPrintPicker.tsx`:
+
+```tsx
+import { FormControlLabel, Checkbox, Box, Typography } from "@mui/material";
+import type { CompanySettingsCustomField } from "../../lib/queries/settings";
+
+interface Props {
+  /** Company custom field definitions, in positional order (index = print key). */

+
+/**
+ * Per-document picker: choose which COMPANY custom fields print on this
+ * document's PDF. Selection is positional (matches the PDF `custom_<i>` keys).
+ * Renders nothing when the company has defined no custom fields.
+ */
+export default function CustomFieldsPrintPicker({
+  fields,
+  selected,
+  disabled = false,
+  onChange,
+}: Props) {
+  const printable = fields.filter((f) => (f.value || "").trim());
+  if (printable.length === 0) return null;
+
+  const toggle = (idx: number, checked: boolean) => {
+    const set = new Set(selected);
+    if (checked) set.add(idx);
+    else set.delete(idx);
+    onChange([...set].sort((a, b) => a - b));
+  };
+
+  return (
+    <Box>
+      <Typography variant="subtitle2" sx={{ mb: 0.5 }}>
+        Vlastní pole na PDF
+      </Typography>
+      {fields.map((f, idx) => {
+        if (!(f.value || "").trim()) return null;
+        const label = (f.name || "").trim() ? `${f.name}: ${f.value}` : f.value;
+        return (
+          <FormControlLabel
+            key={idx}
+            control={
+              <Checkbox
+                size="small"
+                checked={selected.includes(idx)}
+                disabled={disabled}
+                onChange={(e) => toggle(idx, e.target.checked)}

+            }
+            label={<Typography variant="body2">{label}</Typography>}
+          />
+        );
+      })}
+    </Box>
+  );
+}
+```
+
+> Note: indices are keyed off the FULL `fields` array (not the filtered `printable`) so they stay aligned with the PDF's `custom_<i>`, which also enumerates the full array. Empty-value fields are skipped visually but still consume their index.
+
+- [ ] **Step 3: Typecheck**
+
+Run: `npm run typecheck`
+Expected: PASS.
+
+- [ ] **Step 4: Commit**
+
+```bash

+```
+

+
+## Task 7: Frontend — wire the picker into the three detail pages
+
+**Files:**
+
+- Modify: `src/admin/pages/OfferDetail.tsx`
+- Modify: `src/admin/pages/IssuedOrderDetail.tsx`
+- Modify: `src/admin/pages/InvoiceDetail.tsx`
+
+For EACH page, the same four edits. Detail below uses OfferDetail; repeat the pattern for the other two (their company-settings query and edit-lock/editable flags already exist on the page — reuse them; do not add new queries).
+
+- [ ] **Step 1: Import the picker (all three pages)**
+
+```ts
+import CustomFieldsPrintPicker from "../components/document/CustomFieldsPrintPicker";
+```
+
+- [ ] **Step 2: Seed local state from the loaded document**
+
+Add state near the page's other editable-field state, and seed it when the document loads (follow the page's existing seeding pattern — if it copies server data into state in an effect or on query success, add this alongside; if it derives form state via `useState` initializers keyed on the query, match that):
+
+```ts
+const [selectedCustomFields, setSelectedCustomFields] = useState<number[]>([]);
+// when the detail query resolves (same place other fields are seeded):
+//   setSelectedCustomFields(data.selected_custom_fields ?? []);
+```
+
+Respect Rules of Hooks: declare this `useState` with the other hooks, before any early `return`.
+
+- [ ] **Step 3: Render the picker in the editable header/meta area**
+
+Place near the other document-level settings (currency/language). `companySettings` is already loaded on the page via `companySettingsOptions()`. Use the page's existing "is this document editable / not locked by another user" boolean for `disabled` (e.g. `!canEdit` or the locked flag the page already computes):
+
+```tsx
+<CustomFieldsPrintPicker
+  fields={companySettings?.custom_fields ?? []}
+  selected={selectedCustomFields}
+  disabled={!canEdit}
+  onChange={setSelectedCustomFields}
+/>
+```
+
+> Use whatever the page already calls its edit-gate (e.g. `canEdit`, `editable`, `isLockedByOther`). Do NOT invent a new permission — reuse the page's existing flag so the picker locks exactly when the rest of the form does.
+
+- [ ] **Step 4: Include the selection in the save payload**
+
+Find where the page builds its update/create payload (the object passed to the save mutation) and add:
+
+```ts
+selected_custom_fields: selectedCustomFields,
+```
+
+- [ ] **Step 5: Repeat Steps 1-4 for `IssuedOrderDetail.tsx` and `InvoiceDetail.tsx`**
+
+Same edits; the company-settings query, edit-gate flag, and save payload all already exist on each page.
+
+- [ ] **Step 6: Typecheck + lint**
+
+Run: `npm run typecheck && npm run lint`
+Expected: PASS, 0 lint errors (watch `react-hooks/rules-of-hooks` — the new `useState` must precede any early return).
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add src/admin/pages/OfferDetail.tsx src/admin/pages/IssuedOrderDetail.tsx src/admin/pages/InvoiceDetail.tsx
+git commit -m "feat(documents): per-document custom-field print picker on offer/issued-order/invoice detail"
+```
+
+---
+
+## Task 8: Full verification
+
+- [ ] **Step 1: Run the whole server suite**
+
+Run: `npm test`
+Expected: PASS (no regressions; new selected-custom-fields cases green).
+
+- [ ] **Step 2: Typecheck + lint + build**
+
+```bash
+npm run typecheck
+npm run lint
+npm run build
+```
+
+Expected: all PASS; client builds.
+
+- [ ] **Step 3: Manual smoke (user-driven, dev server is theirs)**
+
+Ask the user to: open an offer detail with company custom fields defined → tick one field → save → open its PDF and confirm only that field prints in the company block; confirm an untouched/older document prints no custom fields. Repeat for an issued order and an invoice.
+
+- [ ] **Step 4: Final state check**
+
+```bash
+git status
+git log --oneline -8
+```
+
+Expected: clean tree, the feature commits present.
+
+---
+
+## Self-review notes (addressed)
+
+- **Spec coverage:** storage column (T1), encode/decode (T2), schemas (T3), service persist+decode (T4), PDF filter (T5), frontend types+picker (T6), detail-page wiring (T7), tests throughout + full verify (T8). Order confirmations deliberately untouched. ✅
+- **Default = none:** `buildAddressLines` filters only when passed an array; the company call always passes the parsed selection (default `[]`), so nothing prints until ticked. Customer/supplier calls omit the param ⇒ unchanged. ✅
+- **Positional identity:** indices key off the full `fields` array on both render and picker sides (T5 note, T6 Step 2 note). ✅
+- **Type consistency:** `encodeSelectedCustomFields` / `parseSelectedCustomFields` used with identical signatures across services and PDF routes; detail interfaces expose `number[]`. ✅
+- **Open confirmations flagged inline** (prisma import path in tests; whether each PDF route narrows its document `select`) — each has a grep-first instruction rather than an assumption.

+# Per-item Sleva (% discount) — Offers + Invoices
+
+**Date:** 2026-06-13
+**Status:** Approved → implementing
+**Scope:** Add a per-line-item percentage discount ("Sleva") to **offers**
+(nabídky) and **issued invoices** (Faktury), on both the detail-page item
+editor and the PDF. Received invoices, issued orders and orders are NOT
+touched.
+
+## Decisions (from brainstorming)
+
+- **Type:** percentage per item (0–100), not an absolute amount.
+- **Totals/VAT:** the discount reduces the line **net**; on invoices VAT is
+  computed on the **discounted** net. `net = qty × unit_price × (1 − discount/100)`.
+- **PDF column is conditional:** render the Sleva column only when at least one
+  (included) item has `discount > 0`; otherwise the table is identical to today.
+- **Detail-page column is always visible** (it's the input).
+
+## Data model
+
+Add to `quotation_items` and `invoice_items`:
+
+```
+discount Decimal? @default(0.00) @db.Decimal(5, 2)   // percent, 0–100
+```
+
+Nullable with default `0`, matching the existing money columns. "No sleva" =
+`0` or null. One tracked migration; apply to dev `app` and `app_test`, then
+`prisma generate`.
+
+## Line math (single rule)
+
+`lineNet = qty × unit_price × (1 − clamp(discount,0,100)/100)`
+
+Add a shared backend helper so every site is identical:
+
+```ts
+// src/utils/money.ts (new)
+export const lineNet = (qty: number, unitPrice: number, discountPct: number) =>
+  qty * unitPrice * (1 - (discountPct || 0) / 100);
+```
+
+## Backend
+
+- **Schemas (Zod):** add `discount` to the offer-item and invoice-item schemas
+  via `numberInRange(0, 100)` (shared coercer in `common.ts`), optional, default
+  `0`.
+- **offers.service** (`enrichQuotation`): line total uses `lineNet`; document
+  net ("Celkem bez DPH") sums discounted included lines. Persist `discount` on
+  item create/update.
+- **invoices.service**: every `computeMoney` `getBase` callback
+  (`computeInvoiceTotals`, monthly-stats `invoiceMonthlyAmount`, per-rate
+  `vatMap`) returns `lineNet(...)` so subtotal **and** VAT use the discounted
+  net. Persist `discount` on item create/update.
+- **DocumentItemsEditor's `documentItemsTotal`** (frontend) mirrors the same
+  discounted net.
+
+## Frontend (Section 1 — detail-page editor)
+
+- **Offers** → shared `src/admin/components/document/DocumentItemsEditor.tsx`:
+  `DocumentItem` gains `discount`; add a **"Sleva %"** numeric column (0–100);
+  per-line total and the footer net total apply it. Mobile card layout gets the
+  field. `emptyDocumentItem` defaults `discount: 0`. Hydration + save payloads
+  carry `discount`.
+- **Invoices** → `src/admin/pages/InvoiceDetail.tsx` own editor
+  (`SortableInvoiceRow` + create/edit rows): `InvoiceItem` gains `discount`;
+  same column; net/VAT/gross totals apply it. Mobile layout too.
+
+## PDF (Section 2 — conditional column)
+
+`src/routes/admin/offers-pdf.ts` and `src/routes/admin/invoices-pdf.ts`:
+
+- `const hasDiscount = items.some(i => includedInTotal(i) && Number(i.discount) > 0)`.
+- When `hasDiscount`: add a column — header **"Sleva"** (cs) / **"Discount"**
+  (en, from the document's `language`), cell renders `"<n> %"` (escaped); adjust
+  colspans of any full-width rows accordingly.
+- Line net / document total / VAT always use the discounted net regardless of
+  `hasDiscount`.
+- `escapeHtml` every interpolation (string-built PDF templates).
+
+## Tests
+
+- `offer-invoice-totals` / invoice totals: net, VAT and gross with discounts
+  (incl. a 100% line = 0, and VAT-on-discounted-net).
+- Schema: `discount` rejects <0 and >100, coerces form strings, defaults 0.
+- PDF: column present when an item has a discount; absent when none; values
+  escaped.
+
+## Non-goals (YAGNI)
+
+- No separate "total discount" summary line, no document-level discount.
+- No changes to received invoices, issued orders, or orders.
+
+## Migration etiquette
+
+DB change → user stops the dev server first; create the migration via the
+non-interactive `prisma migrate diff` recipe, `migrate deploy` + `generate` on
+dev and `app_test`, commit schema + migration folder together.

+# Per-document custom-field print selection
+
+**Date:** 2026-06-16
+**Status:** Approved design — ready for implementation plan
+**Scope:** offers (quotations), issued orders, invoices
+
+---
+
+## Problem
+
+Company custom fields are defined in company settings (`company_settings.custom_fields`,
+a JSON blob of `{name, value, showLabel}[]` plus a `field_order`). They render in the
+**sender/company block** of document PDFs via `buildAddressLines(settings, …)`.
+
+Today **every** custom field with a value prints on **every** document PDF (offer, issued
+order, invoice). The only existing per-field control is the company-settings checkbox
+**"Zobrazit název v PDF"** (`showLabel`), which decides whether a printed field shows as
+`Name: Value` or just `Value` — it does **not** control whether the field appears at all.
+
+The user wants per-document control: on each offer / issued order / invoice **detail page**,
+tick which company custom fields actually print on that specific document's PDF.
+
+## Goals
+
+- Each offer, issued order, and invoice independently selects which company custom fields
+  print in its PDF sender block.
+- Selection lives on the document and is editable on its detail page.
+- Default is **none selected** — existing documents and new drafts print no custom fields
+  until fields are deliberately ticked.
+- The company-settings `showLabel` ("Zobrazit název v PDF") checkbox is **unchanged**.
+
+## Non-goals
+
+- Order confirmations ("orders" / `orders-pdf.ts`) are **out of scope** — they keep current
+  behavior (print all custom fields).
+- No change to how custom fields are _defined_ in company settings.
+- No stable per-field IDs — selection is **positional** (see Decisions).
+
+## Decisions (locked)
+
+1. **Default = none selected.** Existing rows get `NULL`; new documents start empty. A
+   document prints custom fields only for the indices it explicitly stores.
+2. **Positional identity.** Selection stores field **positions** (`0,1,2…`) matching the
+   existing `custom_<i>` keys in the PDF code. No settings-structure change, no backfill.
+   Accepted caveat: reordering/deleting a custom field in company settings can shift what a
+   saved document's stored indices point at. Low risk — company fields rarely change, and
+   finalized PDFs are archived on NAS (served as-is, not re-rendered). The user accepted this
+   over the more robust stable-ID approach.
+3. **Scope = 3 document types** (offers, issued orders, invoices). Order confirmations excluded.
+4. **`showLabel` retained** in company settings, untouched.
+
+---
+
+## Design
+
+### 1. Data storage
+
+Add one nullable column to each of `quotations`, `issued_orders`, `invoices`:
+
+| Column                   | Type      | Meaning                                                       |
+| ------------------------ | --------- | ------------------------------------------------------------- |
+| `selected_custom_fields` | `VARCHAR` | JSON array of selected indices, e.g. `"[0,2]"`; `NULL` = none |
+
+Stored as JSON-in-text, consistent with the existing `company_settings.custom_fields` /
+`customers.custom_fields` pattern. `NULL`/empty ⇒ no custom fields print.
+
+One tracked migration per the project's non-interactive `prisma migrate diff` recipe
+(CLAUDE.md). **Apply to `app_test` as well** (`DATABASE_URL=<app_test> npx prisma migrate
+deploy`) or the suite breaks. Commit `schema.prisma` + migration folder together.
+
+### 2. Backend — schemas
+
+Add to each document's **Create and Update** Zod schema:
+
+```ts
+selected_custom_fields: z.array(z.number().int().nonnegative()).max(200).optional(),
+```
+
+Files:
+
+- `src/schemas/offers.schema.ts` — `CreateQuotationSchema` (Update derives via `.partial().omit()`).
+- `src/schemas/issued-orders.schema.ts` — `CreateIssuedOrderSchema` (Update derives via `.partial().omit()`).
+- `src/schemas/invoices.schema.ts` — both `CreateInvoiceSchema` and `UpdateInvoiceSchema`
+  (invoices define the two schemas separately).
+
+### 3. Backend — services
+
+In each create/update service, persist the field inside the **existing transaction**:
+
+- On write: `selected_custom_fields: Array.isArray(body.selected_custom_fields) &&
+body.selected_custom_fields.length > 0 ? JSON.stringify(body.selected_custom_fields) : null`
+- No other logic changes; sits alongside the existing header column assignments.
+
+Files: `src/services/offers.service.ts`, `src/services/issued-orders.service.ts`,
+`src/services/invoices.service.ts`.
+
+### 4. Backend — detail responses
+
+The detail endpoints spread the document row. Decode the stored string back into a
+`number[]` so the frontend receives a clean array (default `[]` when `NULL`/malformed —
+malformed JSON degrades gracefully with a logged warning, per the error convention). Add
+`selected_custom_fields: number[]` to the corresponding detail interfaces in
+`src/admin/lib/queries/{offers,issued-orders,invoices}.ts`.
+
+### 5. PDF rendering
+
+In each of `offers-pdf.ts`, `issued-orders-pdf.ts`, `invoices-pdf.ts`, extend the
+company-block `buildAddressLines()` with an optional parameter:
+
+```ts
+buildAddressLines(entity, isSupplier, t, selectedCustomFields?: number[] | null)
+```
+
+When building `fieldMap`, only emit a `custom_<i>` entry when `selectedCustomFields`
+includes `i`. Behavior:
+
+- `null` / `undefined` / empty array ⇒ **no** custom lines (the new default).
+- Standard address lines (name, street, city/postal, country, IČO/`company_id`,
+  DIČ/`vat_id`) are **unaffected** — always built as today.
+- For the custom fields that _are_ selected, the existing `showLabel` (`Name: Value` vs
+  `Value`) and `field_order` ordering logic is preserved unchanged.
+
+Only the **company/sender** block is filtered (that's where company custom fields render).
+The customer block (offers/invoices) and supplier block (issued orders) keep their own
+custom-field behavior unchanged — those come from `customers`/`sklad_suppliers`, not company
+settings, and are not in scope.
+
+The PDF route reads the document's `selected_custom_fields` column, parses it to `number[]`,
+and passes it into `buildAddressLines(settings, …, selected)`.
+
+> Archived-PDF note: finalized/numbered documents serve their archived NAS copy and won't
+> change retroactively. Drafts (and any forced re-render) reflect the current selection.
+
+### 6. Frontend — shared picker component
+
+New shared component under `src/admin/components/document/` (e.g.
+`CustomFieldsPrintPicker.tsx`), reused by all three detail pages (extend the shared module,
+don't fork three copies — per CLAUDE.md document-module conventions).
+
+Props (shape): the parsed company custom fields (`{name, value}[]` from
+`companySettings.custom_fields`), the current selected indices, an `onChange`, and a
+`disabled` flag.
+
+Behavior:
+
+- Renders a checkbox per company custom field; label shows the field's name (and/or value)
+  so the user knows what each is.
+- Bound to local state on the detail page, seeded from the document's
+  `selected_custom_fields`.
+- Hidden/empty when the company has no custom fields defined.
+- Respects edit-lock and editable-status rules: read-only (`disabled`) when the document
+  isn't editable or is locked by another user, matching how the rest of the header fields
+  behave on that page.
+- Included in the page's save payload as `selected_custom_fields: number[]`.
+
+Pages: `src/admin/pages/OfferDetail.tsx`, `IssuedOrderDetail.tsx`, `InvoiceDetail.tsx` —
+each already loads `companySettingsOptions()`, so the field definitions are available with
+no new query.
+
+Placement: in the editable header/meta area of each detail page, near the other
+document-level settings (currency/language/etc.).
+
+---
+
+## Data flow
+
+```
+Company settings: custom_fields = [{name:"Tel.",…}, {name:"Web",…}, {name:"Datová schránka",…}]
+                                      idx 0           idx 1          idx 2
+
+Offer detail page → user ticks "Tel." and "Datová schránka"
+  → save payload selected_custom_fields: [0, 2]
+  → service stores quotations.selected_custom_fields = "[0,2]"
+
+Offer PDF render
+  → read column "[0,2]" → [0,2]
+  → buildAddressLines(settings, …, [0,2])
+  → fieldMap emits custom_0 ("Tel.: …") and custom_2 ("Datová schránka: …"), skips custom_1
+  → sender block prints Tel. and Datová schránka only
+```
+
+## Testing
+
+Server-side Vitest against `app_test` (no Prisma mocking; mock Puppeteer/NAS only):
+
+- Create/update each document with `selected_custom_fields` → column persists the JSON
+  string; empty/omitted → `NULL`.
+- Detail response decodes to `number[]` (and `[]` for `NULL`).
+- Schema: non-integer / negative entries rejected; omitted is valid.
+- PDF: with a stubbed `html-to-pdf`, assert the rendered company block includes only the
+  selected custom field lines and still includes standard address lines; empty selection ⇒
+  no custom lines; standard lines unaffected.
+- Regression: customer/supplier custom fields still render regardless of company selection.
+
+## Migration & rollout
+
+- One migration adding the three columns (all default `NULL`), applied to dev `app` and
+  `app_test`.
+- No data backfill (none-selected default is the intended post-ship state).
+- No production PDF changes for already-archived documents.
+
+## Affected files (reference)
+
+- `prisma/schema.prisma` (+ new migration folder)
+- `src/schemas/offers.schema.ts`, `issued-orders.schema.ts`, `invoices.schema.ts`
+- `src/services/offers.service.ts`, `issued-orders.service.ts`, `invoices.service.ts`
+- `src/routes/admin/offers-pdf.ts`, `issued-orders-pdf.ts`, `invoices-pdf.ts`
+- (detail route handlers, if decoding is done there rather than in the service)
+- `src/admin/lib/queries/offers.ts`, `issued-orders.ts`, `invoices.ts`
+- `src/admin/components/document/CustomFieldsPrintPicker.tsx` (new)
+- `src/admin/pages/OfferDetail.tsx`, `IssuedOrderDetail.tsx`, `InvoiceDetail.tsx`

+# Status quick actions + project⇄order sync
+
+**Date:** 2026-07-04 · **Status:** Approved (interactive design w/ owner) · **Scope:** offers, received orders, projects
+
+## Problem
+
+Status changes are inconsistent: the Invoices list has a quick chip action (click → confirm → paid),
+but Offers/ReceivedOrders/Projects tables have inert chips — every change needs the detail page.
+ProjectDetail edits status via a free combobox in the form (no transitions, no confirm), unlike
+OfferDetail/OrderDetail's transition buttons. Projects have **no status machine at all** (free-text
+column). Order→project completion sync exists one-way (`syncProjectStatus`), but finishing a
+**project** leaves its linked order untouched.
+
+## Decisions (owner)
+
+1. **Chip opens a menu** of valid next states (not single-click-advance) → ConfirmDialog per pick,
+   danger styling + cascade notes on destructive/irreversible ones.
+2. **Reopen allowed**: `dokonceny/zruseny → aktivni` (projects), `dokoncena/stornovana → v_realizaci`
+   (received orders). **Reopening never cascades** to the linked record.
+3. **Sync scope: finish + cancel, both directions.** Project `dokonceny` ⇄ order `dokoncena`;
+   project `zruseny` ⇄ order `stornovana`.
+4. Offers quick menu: `Aktivovat` (draft — same number-assignment + PDF-archive semantics as the
+   detail), `Zneplatnit` (danger), and **"Vytvořit objednávku…" which opens the existing
+   create-order modal** (never a raw label flip to `ordered` — that state is owned by the
+   create-order flow).
+
+## Design
+
+### Backend
+
+**Projects gain a status machine** (`src/services/projects.service.ts`):
+`VALID_TRANSITIONS = { aktivni: [dokonceny, zruseny], dokonceny: [aktivni], zruseny: [aktivni] }`.
+`updateProject` validates status changes (token `invalid_transition` → Czech 400 in the route);
+a legacy/unknown current status may transition to any canonical value (tolerant). `getProject`
+returns `valid_transitions` (same contract as offers/orders).
+
+**Project → order cascade** (new), inside one transaction with the project update:
+
+- project → `dokonceny` ⇒ linked order → `dokoncena` **iff** order status ∈ {prijata, v_realizaci}
+- project → `zruseny` ⇒ linked order → `stornovana` **iff** order status ∈ {prijata, v_realizaci}
+- reopen ⇒ no order change; completed/cancelled orders are never resurrected by a cascade
+- direct `tx` write (no service recursion); sibling projects of the same order are NOT touched
+  (multi-project orders are a rare schema possibility, not a flow; avoid surprise mass updates)
+- the service returns what cascaded so the route writes an audit row for the order change too
+
+**Received orders** (`src/services/orders.service.ts`):
+
+- `VALID_TRANSITIONS` gains reopen: `dokoncena: [v_realizaci]`, `stornovana: [v_realizaci]`
+- `syncProjectStatus` becomes reopen-aware: given the previous status, a transition OUT of a
+  terminal state (reopen) skips project sync entirely (decision 2). Forward transitions keep the
+  existing mapping (v_realizaci→aktivni no-op in practice, dokoncena→dokonceny,
+  stornovana→zruseny), and the cascaded project change now gets an audit row.
+- item/section edit guards stay status-based, so a reopened order is editable again (intended).
+
+No DB migration (status columns are strings already).
+
+### Frontend
+
+**Shared `StatusChipMenu`** (`src/admin/components/StatusChipMenu.tsx`): renders a `StatusChip`;
+click opens a small MUI `Menu` of actions; each action either opens a `ConfirmDialog`
+(danger variant + `loading` during the request; cascade note in the message) or runs a plain
+`onClick` (the modal-opening offer item). Hidden affordance fixed via `title` tooltip. Chip is
+plain (non-clickable) when the user lacks the edit permission or no actions exist.
+
+**Offers list**: draft → `Aktivovat` (confirm notes the number assignment; after success the same
+fire-and-forget PDF-archive call the detail does); active → `Vytvořit objednávku…` (opens the
+existing modal) + `Zneplatnit` (danger); ordered → `Zneplatnit` (danger).
+
+**ReceivedOrders list**: prijata → `Zahájit realizaci`, `Stornovat` (danger, note: linked project
+will be cancelled); v_realizaci → `Dokončit` (note: linked project will be completed),
+`Stornovat` (danger); dokoncena/stornovana → `Obnovit` (reopen, no cascade note).
+
+**Projects list**: aktivni → `Dokončit` (note when `order_id` present: linked order will be
+completed), `Zrušit` (danger, order-storno note); dokonceny/zruseny → `Obnovit`.
+
+**ProjectDetail**: status `Select` removed from the form (and status removed from the save
+payload); header gains transition buttons rendered from `valid_transitions`
+(`Dokončit projekt` / `Zrušit projekt` danger / `Obnovit projekt`), each via ConfirmDialog with
+cascade notes, as a status-only PUT with its own mutation
+(invalidate: projects, orders, offers, invoices, warehouse). OrderDetail keeps its pattern;
+its transition label shows `Obnovit` when reopening from a terminal state.
+
+Invalidation for all new status mutations: `["orders","offers","projects","invoices"]`
+(+`["warehouse"]` on project mutations, matching the page's existing set).
+
+### Tests
+
+Service-level (real `app_test` DB): project transition validation (all legal/illegal edges incl.
+legacy-status tolerance), project→order cascade both mappings + the guard (no cascade onto
+dokoncena/stornovana orders), reopen-no-cascade both directions, order reopen transitions, and
+regression: order→project sync still fires on forward transitions.
+
+## Out of scope
+
+Offer machine changes (unchanged: draft→active→ordered/invalidated), issued orders, sibling-project
+propagation, ReceivedOrders detail-page button changes beyond the automatic reopen button.
