+
+_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.

+# 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.
