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

+# MUI Migration — Phase 0: Theming Foundation — 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:** Stand up the MUI theming foundation — install MUI, build `theme.ts` (light+dark from existing tokens), wire the provider + `data-theme` color-scheme bridge + `ThemeContext` sync, apply the token-level palette refresh app-wide, and ship a dev-only `/ui-kit` route proving the theme on the first wrappers (`Button`/`Card`/`TextField`).
+
+**Architecture:** MUI's CSS-variable theme is configured with `colorSchemeSelector: "[data-theme='%s']"` so it reads the same `data-theme` attribute `ThemeContext` already writes — one toggle drives both MUI and legacy CSS. A tiny sync component mirrors the attribute into MUI's JS color-scheme state. `ScopedCssBaseline` scopes MUI's reset to migrated subtrees (here, only `/ui-kit`); legacy pages keep `base.css`.
+
+**Tech Stack:** React 18.3, Vite 8, TypeScript (strict), MUI v7 (`@mui/material`) + Emotion + MUI X v8 pickers, Vitest (node).
+
+**Spec:** `docs/superpowers/specs/2026-06-06-css-mui-migration-design.md` (§3, §4, §7 token-level layer, §8 Phase 0).
+
+**Scope note:** This plan is Phase 0 ONLY. The rest of the `ui/` kit (Modal, Toast, Select, Switch, Tabs, DataTable, DatePicker), the AppShell (Phase 1), and the Vozidla pilot (Phase 2) are separate plans.

+## Task 1: Install dependencies and reconcile React types
+
+**Files:**
+
+- Modify: `package.json` (via npm)
+
+- [ ] **Step 1: Install MUI + Emotion + X pickers**
+
+Run (date-fns ^4 is already a dependency):
+
+```bash
+npm install @mui/material@^7 @emotion/react@^11 @emotion/styled@^11 @mui/x-date-pickers@^8
+```
+
+Expected: packages added to `dependencies`; no peer-dependency errors that block install.
+
+- [ ] **Step 2: Reconcile `@types/react` to the React 18 runtime**
+
+The repo runs `react@^18.3.1` but pins `@types/react@^19`. MUI's component types are sensitive to the `@types/react` major. Align the types to the runtime:
+
+```bash
+npm install -D @types/react@^18.3 @types/react-dom@^18.3
+```
+
+Expected: devDependencies now show `@types/react@^18.3.x`.
+
+- [ ] **Step 3: Verify the project still type-checks and builds**
+
+Run:
+
+```bash
+npx tsc -b --noEmit
+npm run build:client
+```
+
+Expected: both succeed with no errors (this is the pre-change baseline; if `tsc` was already failing, capture that before proceeding).
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add package.json package-lock.json
+git commit -m "build(mui): add MUI v7 + Emotion + X pickers; align @types/react to 18"
+```
+
+---
+
+## Task 2: Create `theme.ts` with light/dark palettes (TDD)
+
+**Files:**
+
+- Create: `src/admin/theme.ts`
+- Test: `src/admin/theme.test.ts`
+
+Token values are taken from `src/admin/variables.css` (`[data-theme="light"]` / `[data-theme="dark"]`).
+
+- [ ] **Step 1: Write the failing test**
+
+Create `src/admin/theme.test.ts`:
+
+```ts
+import { describe, it, expect } from "vitest";
+import { theme } from "./theme";
+
+describe("MUI theme", () => {
+  it("uses the brand fonts", () => {
+    expect(theme.typography.fontFamily).toContain("Plus Jakarta Sans");
+    expect(String(theme.typography.h1.fontFamily)).toContain("Urbanist");
+  });
+
+  it("maps the brand red per color scheme", () => {
+    expect(theme.colorSchemes.light.palette.primary.main).toBe("#c73030");
+    expect(theme.colorSchemes.dark.palette.primary.main).toBe("#d63031");
+  });
+
+  it("maps the refreshed light canvas + paper", () => {
+    expect(theme.colorSchemes.light.palette.background.default).toBe("#f4f3f1");
+    expect(theme.colorSchemes.light.palette.background.paper).toBe("#ffffff");
+  });
+
+  it("maps semantic colors per scheme", () => {
+    expect(theme.colorSchemes.light.palette.error.main).toBe("#b91c1c");
+    expect(theme.colorSchemes.dark.palette.success.main).toBe("#22c55e");
+  });
+
+  it("uses the base radius of 10", () => {
+    expect(theme.shape.borderRadius).toBe(10);
+  });
+});
+```
+
+- [ ] **Step 2: Run the test to verify it fails**
+
+Run:
+
+```bash
+npx vitest run src/admin/theme.test.ts
+```
+
+Expected: FAIL — `Cannot find module './theme'` (or `theme` is undefined).
+
+- [ ] **Step 3: Implement `theme.ts` (palettes/typography/shape only — overrides come in Task 3)**
+
+Create `src/admin/theme.ts`:
+
+```ts
+import { createTheme } from "@mui/material/styles";
+
+const FONT_BODY = "'Plus Jakarta Sans', system-ui, sans-serif";
+const FONT_HEADING = "'Urbanist', sans-serif";
+const FONT_MONO = "'DM Mono', Menlo, monospace";
+
+export const theme = createTheme({

+
+// Re-exported for tasks/components that need the mono stack.
+export const fonts = {
+  body: FONT_BODY,
+  heading: FONT_HEADING,
+  mono: FONT_MONO,
+};
+```
+
+- [ ] **Step 4: Run the test to verify it passes**
+
+Run:
+
+```bash
+npx vitest run src/admin/theme.test.ts
+```
+
+Expected: PASS (5 tests).
+
+- [ ] **Step 5: Commit**

+## Task 3: Add component overrides (the "Soft-SaaS" defaults)
+
+**Files:**
+
+- Modify: `src/admin/theme.ts`
+- Test: `src/admin/theme.test.ts`
+
+- [ ] **Step 1: Add a failing assertion for the overrides**
+
+Append to `src/admin/theme.test.ts` (inside the `describe`):
+
+```ts
+it("makes buttons pill-shaped and cards 16px by default", () => {
+  const btn = theme.components?.MuiButton?.styleOverrides?.root as any;
+  expect(btn?.borderRadius).toBe(999);
+  const card = theme.components?.MuiCard?.styleOverrides?.root as any;

+});
+```
+
+- [ ] **Step 2: Run to verify it fails**
+
+Run:
+
+```bash
+npx vitest run src/admin/theme.test.ts
+```
+
+Expected: FAIL — `theme.components` is undefined / `borderRadius` is undefined.
+
+- [ ] **Step 3: Add `components` to the `createTheme` call**

+## Task 4: MUI provider + color-scheme sync
+
+**Files:**
+
+- Create: `src/admin/ui/MuiColorSchemeSync.tsx`
+- Create: `src/admin/ui/MuiProvider.tsx`
+- Modify: `src/admin/AdminApp.tsx`
+
+- [ ] **Step 1: Create the sync component**
+
+Create `src/admin/ui/MuiColorSchemeSync.tsx`:
+
+```tsx
+import { useEffect } from "react";
+import { useColorScheme } from "@mui/material/styles";
+import { useTheme as useAppTheme } from "../../context/ThemeContext";
+
+/**
+ * ThemeContext is the single owner of the `data-theme` attribute. This mirrors
+ * its value into MUI's JS color-scheme state so theme.applyStyles('dark') and
+ * useColorScheme().mode stay in sync with the attribute the CSS selector reads.
+ */
+export default function MuiColorSchemeSync() {
+  const { theme } = useAppTheme();
+  const { mode, setMode } = useColorScheme();
+
+  useEffect(() => {
+    if (mode !== theme) setMode(theme as "light" | "dark");
+  }, [theme, mode, setMode]);
+
+  return null;
+}
+```
+
+- [ ] **Step 2: Create the provider wrapper**
+
+Create `src/admin/ui/MuiProvider.tsx`:
+
+```tsx
+import type { ReactNode } from "react";
+import { ThemeProvider } from "@mui/material/styles";
+import { theme } from "../theme";
+import MuiColorSchemeSync from "./MuiColorSchemeSync";
+
+export default function MuiProvider({ children }: { children: ReactNode }) {
+  return (
+    <ThemeProvider theme={theme} defaultMode="dark">
+      <MuiColorSchemeSync />
+      {children}
+    </ThemeProvider>
+  );
+}
+```
+
+- [ ] **Step 3: Mount the provider at the top of `AdminApp`**
+
+In `src/admin/AdminApp.tsx`, add the import after the other component imports (e.g. after line 10):
+
+```tsx
+import MuiProvider from "./ui/MuiProvider";
+```
+
+Then wrap the existing returned tree. Change:
+
+```tsx
+  return (
+    <AuthProvider>
+```
+
+to:
+
+```tsx
+  return (
+    <MuiProvider>
+      <AuthProvider>
+```
+
+and change the matching closing tag at the end of the JSX:
+
+```tsx
+      </AuthProvider>
+  );
+```
+
+to:
+
+```tsx
+      </AuthProvider>
+    </MuiProvider>
+  );
+```
+
+- [ ] **Step 4: Verify the app builds and renders with no console errors**
+
+Run:
+
+```bash
+npx tsc -b --noEmit
+npm run build:client
+```
+
+Expected: both succeed. (The user runs the dev server separately — do not start it. Verification of live render happens via the `/ui-kit` route in Task 6.)
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/admin/ui/MuiProvider.tsx src/admin/ui/MuiColorSchemeSync.tsx src/admin/AdminApp.tsx
+git commit -m "feat(mui): mount MUI provider + sync color scheme to data-theme"
+```
+

+
+## Task 5: First UI-kit wrappers + barrel
+
+**Files:**
+
+- Create: `src/admin/ui/Button.tsx`, `src/admin/ui/Card.tsx`, `src/admin/ui/TextField.tsx`, `src/admin/ui/index.ts`
+
+- [ ] **Step 1: Create the wrappers**
+
+Create `src/admin/ui/Button.tsx`:
+
+```tsx
+import MuiButton, { type ButtonProps } from "@mui/material/Button";
+
+/** App Button: defaults to the brand primary contained style. */
+export default function Button(props: ButtonProps) {
+  return <MuiButton variant="contained" color="primary" {...props} />;
+}
+```
+
+Create `src/admin/ui/Card.tsx`:
+
+```tsx
+import MuiCard, { type CardProps } from "@mui/material/Card";
+import CardContent from "@mui/material/CardContent";
+
+export default function Card({ children, ...props }: CardProps) {
+  return (
+    <MuiCard {...props}>
+      <CardContent>{children}</CardContent>
+    </MuiCard>
+  );
+}
+```
+
+Create `src/admin/ui/TextField.tsx`:
+
+```tsx
+import MuiTextField, { type TextFieldProps } from "@mui/material/TextField";
+
+/** App TextField: small + outlined + full width by default. */
+export default function TextField(props: TextFieldProps) {
+  return <MuiTextField size="small" variant="outlined" fullWidth {...props} />;
+}
+```
+
+- [ ] **Step 2: Create the barrel**
+
+Create `src/admin/ui/index.ts`:
+
+```ts
+export { default as MuiProvider } from "./MuiProvider";
+export { default as Button } from "./Button";
+export { default as Card } from "./Card";
+export { default as TextField } from "./TextField";
+```
+
+- [ ] **Step 3: Verify type-check**
+
+Run:
+
+```bash
+npx tsc -b --noEmit
+```
+
+Expected: PASS.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/admin/ui/Button.tsx src/admin/ui/Card.tsx src/admin/ui/TextField.tsx src/admin/ui/index.ts
+git commit -m "feat(mui): first ui-kit wrappers (Button, Card, TextField) + barrel"
+```

+
+## Task 6: Dev-only `/ui-kit` showcase route
+
+**Files:**
+
+- Create: `src/admin/pages/UiKit.tsx`
+- Modify: `src/admin/AdminApp.tsx`
+
+- [ ] **Step 1: Create the showcase page**
+
+Create `src/admin/pages/UiKit.tsx`:
+
+```tsx
+import ScopedCssBaseline from "@mui/material/ScopedCssBaseline";
+import Box from "@mui/material/Box";
+import Stack from "@mui/material/Stack";
+import Typography from "@mui/material/Typography";
+import Chip from "@mui/material/Chip";
+import { Button, Card, TextField } from "../ui";
+import { useTheme } from "../../context/ThemeContext";
+
+export default function UiKit() {
+  const { theme, toggleTheme } = useTheme();
+  return (
+    <ScopedCssBaseline>
+      <Box sx={{ p: 4, minHeight: "100vh", bgcolor: "background.default" }}>
+        <Stack direction="row" alignItems="center" spacing={2} mb={3}>
+          <Typography variant="h4">UI Kit</Typography>
+          <Button color="inherit" variant="outlined" onClick={toggleTheme}>
+            Theme: {theme}
+          </Button>
+        </Stack>
+
+        <Stack spacing={3} sx={{ maxWidth: 520 }}>
+          <Card>
+            <Typography variant="h6" gutterBottom>
+              Faktury
+            </Typography>
+            <Typography color="text.secondary" gutterBottom>
+              12 vystavených tento měsíc
+            </Typography>
+            <Stack direction="row" spacing={1} mb={2}>
+              <Chip label="Zaplaceno" color="success" size="small" />
+              <Chip label="Po splatnosti" color="error" size="small" />
+            </Stack>
+            <TextField
+              label="Hledat fakturu"
+              placeholder="Číslo nebo klient…"
+            />
+            <Box mt={2}>
+              <Button>Nová faktura</Button>
+            </Box>
+          </Card>
+        </Stack>
+      </Box>
+    </ScopedCssBaseline>
+  );
+}
+```
+
+- [ ] **Step 2: Register the route, DEV-only**
+
+In `src/admin/AdminApp.tsx`, add the lazy import alongside the other lazy pages (after line 11's eager imports / with the `lazy(...)` block):
+
+```tsx
+const UiKit = lazy(() => import("./pages/UiKit"));
+```
+
+Then, inside `<Routes>`, add a sibling route to `login` (so the showcase renders without the shell), guarded so it is dropped from production builds:
+
+```tsx
+{
+  import.meta.env.DEV && <Route path="ui-kit" element={<UiKit />} />;
+}
+```
+
+- [ ] **Step 3: Verify build (prod) excludes it and type-check passes**
+
+Run:
+
+```bash
+npx tsc -b --noEmit
+npm run build:client
+```
+
+Expected: both succeed. `import.meta.env.DEV` is `false` in the production build, so the route is tree-shaken.
+
+- [ ] **Step 4: Manual + Playwright verification**
+
+The user runs the dev server. Once it's up, verify at `/ui-kit`:
+
+- Card, button (red gradient, pill), chips (tinted), and text field render in the Soft-SaaS style.
+- Clicking **Theme: dark/light** flips `data-theme` and **both MUI components AND the page background** swap — proving the `colorSchemeSelector` bridge works.
+- No new console errors.
+
+Capture baseline screenshots with the available Playwright tooling (light + dark) and save under `docs/superpowers/visual-baselines/phase-0-ui-kit-{light,dark}.png`.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/admin/pages/UiKit.tsx src/admin/AdminApp.tsx
+git commit -m "feat(mui): dev-only /ui-kit showcase proving the theme + data-theme bridge"
+```
+
+---
+
+## Task 7: Token-level palette refresh (app-wide)
+
+**Files:**
+
+- Modify: `src/admin/variables.css`
+
+Per spec §7, the token-level palette refresh is applied app-wide so migrated and legacy pages share the refreshed palette. The only token change for Phase 0 is the light canvas (the new look's `#f4f3f1` vs current `#f5f4f2`); chip/structure changes are component-level (MUI) and need no token edit.
+
+- [ ] **Step 1: Update the light canvas token**
+
+In `src/admin/variables.css`, inside the `[data-theme="light"]` block, change:
+
+```css
+--bg-primary: #f5f4f2;
+```
+
+to:
+
+```css
+--bg-primary: #f4f3f1;
+```
+
+- [ ] **Step 2: Verify build**
+
+Run:
+
+```bash
+npm run build:client
+```
+
+Expected: succeeds.
+
+- [ ] **Step 3: Manual check**
+
+With the dev server (user-run), confirm in light mode the app canvas is the refreshed `#f4f3f1` and nothing else shifted structurally. (This is the deliberate, minor app-wide color change noted in the spec — not a no-op.)
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/admin/variables.css
+git commit -m "style(tokens): refresh light canvas to #f4f3f1 (two-layer refresh, token level)"
+```
+
+---
+
+## Task 8: Phase-0 release verification
+
+**Files:** none (verification + tag)
+
+- [ ] **Step 1: Full type-check, unit tests, and build**
+
+Run:
+
+```bash
+npx tsc -b --noEmit
+npx vitest run src/admin/theme.test.ts
+npm run build
+```
+
+Expected: `tsc` clean; 6 theme tests pass; server + client build succeed.
+
+- [ ] **Step 2: Backend test suite still green (server untouched)**
+
+Run:
+
+```bash
+npm test
+```
+
+Expected: existing `auth` + `numbering` suites pass (Phase 0 changed no server code).
+
+- [ ] **Step 3: Definition-of-done checklist (manual, dev server)**
+
+- `/ui-kit` renders Button/Card/TextField/Chip in the Soft-SaaS style in **both** themes.
+- Theme toggle flips `data-theme` and swaps MUI + legacy colors together; MUI's `useColorScheme().mode` matches (no console warnings).
+- No new console errors on any existing page (the provider mount + token refresh are non-breaking).
+- Light canvas is `#f4f3f1`.
+- Production build excludes the `/ui-kit` route.
+
+- [ ] **Step 4: Tag/release per the project release process**
+
+Follow `CLAUDE.md` "Release Process" (bump `package.json`, build, tag, deploy) when shipping Phase 0. No Prisma migration is involved (frontend-only).
+
+---
+
+## Self-review notes (for the controller)
+
+- **Spec coverage:** Phase 0 items from spec §8 are all covered — deps + `@types/react` (Task 1), `theme.ts` light/dark (Tasks 2–3), provider + `ScopedCssBaseline` + `ThemeContext`↔`setMode` sync (Tasks 4, 6), dev-only `/ui-kit` (Task 6), token-level refresh (Task 7). The full `ui/` kit, AppShell, and Vozidla are explicitly deferred to later plans (scope note).
+- **Type consistency:** `theme` (named export) is used consistently in `theme.test.ts`, `MuiProvider.tsx`. `useTheme` refers to the app's `ThemeContext` (aliased `useAppTheme` in the sync component to avoid colliding with MUI's `useTheme`). Wrappers are default exports re-exported via the barrel.
+- **Open risk to verify in Task 1/6:** exact MUI v7 API for `cssVariables.colorSchemeSelector` + `ThemeProvider` `defaultMode` — confirm against the installed version's docs; if `defaultMode` belongs on a different provider in the installed version, adjust in Task 4.

+# MUI Migration — Phase 1: AppShell — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax.
+
+**Goal:** Replace the admin chrome (`AdminLayout` + `Sidebar`) with a MUI `<AppShell>` in the Soft-SaaS look — a `Drawer`-based sidebar (permanent on desktop, temporary on mobile) with a white active "pill", a minimal topbar (hamburger + theme toggle), reusing the existing permission-filtered nav data and preserving all behavior (auth/2FA guards, logout scale+blur animation, ShortcutsHelp).
+
+**Architecture:** The valuable, well-tested parts are **reused, not rewritten**: the `menuSections` nav data (icons, permissions, active-match rules) and the active/permission logic move into `navData.tsx`. `SidebarNav` renders that data with MUI `List`. `AppShell` provides the responsive `Drawer` + topbar + auth guards + the framer-motion logout wrapper, and renders `<Outlet/>`. `AdminLayout`/`Sidebar`/`layout.css` are deleted when `AppShell` lands.
+
+**Tech Stack:** React 18.3, MUI v7 (`@mui/material`), Emotion, framer-motion (kept for logout), react-router v6, TypeScript strict.
+
+**Spec:** `docs/superpowers/specs/2026-06-06-css-mui-migration-design.md` (§5 AppShell, §7 aesthetic, §8 Phase 1, §9 animation).
+
+**Authoritative gates:** `npx tsc -b --noEmit` (NOT `-p tsconfig.json` — that's a vacuous solution file), `npm run build:client`, `npx vitest run`. Live visual verification (dev server) is the USER's; implementers do build/typecheck/tests only and must NOT start the dev server.
+
+**Behavior parity checklist (must all be preserved from `AdminLayout.tsx` + `Sidebar.tsx`):**
+
+- Auth: `loading` → spinner; `!isAuthenticated` → `<Navigate to="/login" replace/>`; 2FA-setup redirect (`user.require2FA && !user.totpEnabled && pathname !== "/"` → `/`).
+- Logout: `handleLogout` sets a logout alert (`setLogoutAlert()`), closes the mobile drawer, and calls `logout()` after 400ms; the layout plays the framer-motion `{scale:1.5, opacity:0, filter:"blur(12px)"}` exit over 0.4s.
+- Sidebar: permission-filtered sections/items (empty sections hidden); custom active matching (`matchPrefix`/`matchAlso`/`matchExclude`/`end`); company logo with light/dark variant + `onError` fallback to `/images/logo-{dark,light}.png`; user chip (avatar initial + name + `roleDisplay`); logout button; mobile open/close.
+- `ShortcutsHelp` still rendered; `<Outlet/>` for page content.

+Import paths from `src/admin/ui/` (same depth as `components/`): `../context/AuthContext`, `../../context/ThemeContext`, `../utils/api`, `../hooks/...`, `../theme`.
+

+
+## Task 1: Extract nav data into `navData.tsx`
+
+**Files:** Create `src/admin/ui/navData.tsx`; Modify `src/admin/components/Sidebar.tsx`.
+
+- [ ] **Step 1: Create `src/admin/ui/navData.tsx`.** MOVE (cut) the following from `src/admin/components/Sidebar.tsx` **verbatim**: the `MenuItem` and `MenuSection` interfaces and the entire `menuSections` array (all 6 sections with their inline SVG icons — do not retype, move them unchanged). Then add the two pure helpers (extracted from Sidebar's inline closures), and export everything:
+
+```tsx
+import { type ReactNode } from "react";
+
+export interface MenuItem {
+  path: string;
+  label: string;
+  end?: boolean;
+  permission?: string | string[];
+  matchPrefix?: string;
+  matchAlso?: string[];
+  matchExclude?: string[];
+  icon: ReactNode;
+}
+
+export interface MenuSection {
+  label: string;
+  items: MenuItem[];
+}
+
+export const menuSections: MenuSection[] = [
+  /* ... the 6 sections, MOVED verbatim from Sidebar.tsx ... */
+];
+
+/** Active-state matching (mirrors the original Sidebar logic, incl. matchAlso). */
+export function isItemActive(item: MenuItem, pathname: string): boolean {
+  if (item.matchPrefix) {
+    let active = pathname.startsWith(item.matchPrefix);
+    if (active && item.matchExclude) {
+      active = !item.matchExclude.some((ex) => pathname.startsWith(ex));
+    }
+    if (!active && item.matchAlso) {
+      active = item.matchAlso.some((p) => pathname.startsWith(p));
+    }
+    return active;
+  }
+  if (item.matchAlso && item.matchAlso.some((p) => pathname.startsWith(p))) {
+    return true;
+  }
+  if (item.end) return pathname === item.path;
+  return pathname.startsWith(item.path);
+}
+
+/** Permission check: true if no permission, or any listed permission is held. */
+export function hasItemPermission(
+  item: MenuItem,
+  hasPermission: (p: string) => boolean,
+): boolean {
+  if (!item.permission) return true;
+  if (Array.isArray(item.permission)) {
+    return item.permission.some((p) => hasPermission(p));
+  }
+  return hasPermission(item.permission);
+}
+```
+
+> Note: the original Sidebar computed `matchAlso` separately in the `NavLink` className callback. The consolidated `isItemActive` above folds `matchAlso` in so a single function is the source of truth. Preserve every section/item exactly.
+
+- [ ] **Step 2: Update `Sidebar.tsx` to import from `navData`** (interim — Sidebar is deleted in Task 4). Remove the inline `MenuItem`/`MenuSection`/`menuSections` definitions and the inline `isItemActive`/`hasItemPermission`; import them from `../ui/navData`. In the `NavLink` `className` callback, replace the inline active+matchAlso logic with `isItemActive(item, location.pathname)`.
+
+- [ ] **Step 3: Verify** — `npx tsc -b --noEmit` clean; `npm run build:client` succeeds; `npx vitest run` (147 pass — no behavior change).
+
+- [ ] **Step 4: Commit** `src/admin/ui/navData.tsx` + `src/admin/components/Sidebar.tsx` (msg: `refactor(mui): extract sidebar nav data + active/permission helpers to navData`; end with the `Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>` trailer).
+
+---
+
+## Task 2: `SidebarNav.tsx` (MUI drawer content)
+
+**Files:** Create `src/admin/ui/SidebarNav.tsx`.
+
+Renders the permission-filtered nav with MUI. Props: `{ onNavigate?: () => void; onLogout: () => void }` (`onNavigate` closes the mobile drawer; `onLogout` is owned by `AppShell`).
+
+- [ ] **Step 1: Create the component.** Requirements (write complete MUI code):
+  - `const { user, hasPermission } = useAuth();` (`../context/AuthContext`), `const { theme } = useTheme();` aliased from `../../context/ThemeContext`, `const location = useLocation();`.
+  - `visibleSections` = `menuSections` mapped to filter items by `hasItemPermission(item, hasPermission)`, dropping empty sections.
+  - Root: a flex column `Box`, `height: "100%"`, padding ~`1.5`.
+  - **Logo header:** `Box component="img"` with `src` = `/api/admin/company-settings/logo?variant=${theme === "dark" ? "dark" : "light"}` and `onError` falling back to `/images/logo-${theme}.png`; `sx={{ maxHeight: 40, maxWidth: "100%", objectFit: "contain" }}`.
+  - **Nav:** scrollable `Box` (`flex: 1, overflowY: "auto"`). For each section: a `Typography variant="caption"` subheader (uppercase, `letterSpacing: ".06em"`, `fontWeight: 700`, `color: "text.secondary"`, `fontSize: ".64rem"`, `px: 1.5`), then a `List disablePadding` of items. Each item:
+    ```tsx
+    <ListItemButton
+      component={NavLink}
+      to={item.path}
+      end={item.end}
+      onClick={onNavigate}
+      selected={isItemActive(item, location.pathname)}

+- [ ] **Step 3: Commit** `src/admin/ui/AppShell.tsx` (msg: `feat(mui): AppShell — responsive Drawer + topbar, guards + logout animation`; + trailer).
+
+---
+
+## Task 4: Wire `AppShell`, delete legacy chrome
+
+**Files:** Modify `src/admin/AdminApp.tsx`; Delete `src/admin/components/AdminLayout.tsx`, `src/admin/components/Sidebar.tsx`, `src/admin/layout.css`.
+
+- [ ] **Step 1: Swap the route.** In `src/admin/AdminApp.tsx`: change the import `import AdminLayout from "./components/AdminLayout";` → `import AppShell from "./ui/AppShell";`, and the route `<Route element={<AdminLayout />}>` → `<Route element={<AppShell />}>`. Remove the line `import "./layout.css";`.
+
+- [ ] **Step 2: Delete** `src/admin/components/AdminLayout.tsx`, `src/admin/components/Sidebar.tsx`, and `src/admin/layout.css`. Then grep the repo for any remaining import of those modules and fix/remove (there should be none beyond AdminApp).
+
+- [ ] **Step 3: Verify (full gates)** — `npx tsc -b --noEmit` clean; `npm run build` (server+client) succeeds and the prod bundle has no broken refs; `npx vitest run` (147 pass). Confirm `layout.css` is no longer imported anywhere.
+
+- [ ] **Step 4: Commit** (msg: `feat(mui): adopt AppShell, remove AdminLayout/Sidebar/layout.css`; + trailer).
+
+- [ ] **Step 5: MANUAL verification (USER, dev server) — deferred:** sidebar shows permission-filtered sections; active item is the white pill; navigation works + closes the mobile drawer; theme toggle works; logout plays the scale+blur animation; logo light/dark + fallback; responsive (permanent drawer ≥ md, hamburger + temporary drawer < md); no console errors; dark + light both correct.
+
+---
+
+## Self-review notes (for the controller)
+
+- **Spec coverage:** Phase 1 (spec §8) — AppShell chrome via MUI Drawer + topbar (Tasks 2–4), reusing nav data/permissions (Task 1), preserving the logout animation + guards (Task 3), deleting `layout.css` (Task 4). Login stays OUT of this (it's a sibling route — Phase 3), untouched.
+- **Type consistency:** `navData` exports `MenuItem`/`MenuSection`/`menuSections`/`isItemActive`/`hasItemPermission`; `SidebarNav` and (interim) `Sidebar` both consume them. `AppShell` props to `SidebarNav`: `onLogout` (required), `onNavigate` (optional).
+- **Parity risks to watch in review:** the consolidated `isItemActive` must reproduce the original `matchAlso` behavior (the original applied `matchAlso` only in the NavLink callback) — the spec reviewer must diff active states for `/attendance/admin` (matchAlso `/attendance/create`,`/attendance/location`) and `/offers` (matchExclude). The `selected` prop must not double-apply with NavLink's own active class. `ScopedCssBaseline` wraps the shell so MUI reset applies; unmigrated page content inside `<Outlet/>` still uses its own CSS.
+- **Deferred:** all live visual checks (no dev server in implementer scope).

+# MUI Migration — Phase 2: Data/Form Kit + Vozidla Pilot — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development. Steps use checkbox (`- [ ]`) syntax.
+
+**Goal:** Build the data + form foundation components (`DataTable`, `Modal`, `ConfirmDialog`, field controls) and migrate the **Vozidla (Vehicles)** page fully onto them — the pilot that battle-tests the kit. Behavior stays identical; styling becomes MUI (Soft-SaaS shell + dense table).
+
+**Architecture:** New wrappers in `src/admin/ui/` expose stable, app-friendly APIs (Czech labels) over MUI `Dialog`/`Table`/form controls, so pages import from `ui/` not `@mui`. `Modal`/`ConfirmDialog` preserve the existing `FormModal`/`ConfirmModal` prop shapes so page churn is minimal. `DataTable` is a small dense table that takes a `columns` config + `rows` + optional row actions. Vozidla is then rewritten to use them; its data hooks (`useQuery(vehicleListOptions)`, `useApiMutation`) are unchanged.
+
+**Tech Stack:** React 18.3, MUI v7 (`@mui/material`), Emotion, framer-motion (page-entry animations kept), TanStack Query v5, TypeScript strict.
+
+**Spec:** `docs/superpowers/specs/2026-06-06-css-mui-migration-design.md` (§5 kit, §5.1 DataTable, §7 dense-table aesthetic, §8 Phase 2).
+
+**Authoritative gates:** `npx tsc -b --noEmit`, `npm run build`, `npx vitest run` (expect 148). Live visual check (dev server) is the USER's; implementers do build/typecheck/tests only and must NOT start the dev server.
+
+**Reference (current Vozidla behavior to preserve):** `src/admin/pages/Vehicles.tsx` — list table (SPZ, Název, Značka/Model, Počáteční km, Aktuální km, Počet jízd, Stav, Akce) with `formatKm`; inactive rows dimmed; status badge toggles active/inactive via `toggleVehicle`; row actions edit/delete; add/edit `FormModal` with SPZ (uppercased)/Název (required) + Značka/Model/Počáteční km/aktivní checkbox + validation (`Zadejte SPZ`/`Zadejte název`); delete `ConfirmModal`; permission gate `vehicles.manage` → `<Forbidden/>`; empty state.

+## Task 3: Field controls (`Field` + `SwitchField`)
+
+**Files:** Create `src/admin/ui/Field.tsx`; Modify `src/admin/ui/index.ts`.
+
+- [ ] **Step 1: Create `Field.tsx`** with a labeled wrapper and a boolean switch:
+
+```tsx
+import type { ReactNode } from "react";
+import Box from "@mui/material/Box";
+import Typography from "@mui/material/Typography";
+import FormControlLabel from "@mui/material/FormControlLabel";
+import Switch from "@mui/material/Switch";
+
+export function Field({

+
+- [ ] **Step 2:** add `export { Field, SwitchField } from "./Field";` to `index.ts`. (`Button`, `Card`, `TextField` are already exported.)
+- [ ] **Step 3: Verify** `npx tsc -b --noEmit` clean; `npm run build:client` succeeds.
+- [ ] **Step 4: Commit** (msg `feat(mui): Field + SwitchField form controls`; + trailer).
+
+---
+
+## Task 4: Migrate `Vehicles.tsx` onto the kit
+
+**Files:** Modify `src/admin/pages/Vehicles.tsx`.
+
+- [ ] **Step 1: Rewrite the page** keeping ALL existing data logic (the `useQuery(vehicleListOptions)`, `saveVehicle`/`deleteVehicle`/`toggleVehicle` `useApiMutation`s, validation, handlers, permission gate) UNCHANGED, and swapping only the presentation:
+  - Permission gate + loading + empty state: keep behavior; render loading with the existing `admin-spinner` (still in base.css), or a MUI `CircularProgress` — keep `admin-spinner` for now.
+  - Page header: an MUI `Box` (flex, title `Typography variant="h4"` "Správa vozidel" + the kit `Button` "Přidat vozidlo" with the plus SVG). Keep the framer-motion entry animation if desired (optional).
+  - List: kit `Card` wrapping a `DataTable<Vehicle>` with columns: SPZ (`mono`), Název, Značka/Model (the existing `brand/model` join with `—` fallback), Počáteční km (`align right`, `mono`, `formatKm(...) + " km"`), Aktuální km (right/mono), Počet jízd (right/mono), Stav (a clickable MUI `Chip` colored `success`/`default` toggling `toggleActive`), Akce (edit + delete `IconButton`s with the existing SVGs). `rowInactive: (v) => !v.is_active`. `empty` = the existing empty-state block (can keep markup or render a simple MUI message + Button).
+  - Add/Edit modal: kit `Modal` (`isOpen={showModal}`, `onClose`, `onSubmit={handleSubmit}`, `title`, `loading={saving}`) containing `Field`-wrapped kit `TextField`s for SPZ (uppercase onChange)/Název/Značka/Model, a number `TextField` (type="number") for Počáteční km with the hint, and a `SwitchField` for `is_active`. Wire `errors`/`setErrors` exactly as today.
+  - Delete: kit `ConfirmDialog` (`isOpen={deleteConfirm.show}`, `onConfirm={handleDelete}`, `confirmVariant="danger"`, the existing message).
+  - Remove imports of the old `FormModal`/`ConfirmModal`/`FormField`; import from `../ui`.
+
+- [ ] **Step 2: Verify** — `npx tsc -b --noEmit` clean; `npm run build:client` succeeds; `npx vitest run` (148 pass — no test touches this page, but confirm nothing broke).
+- [ ] **Step 3: Commit** (msg `feat(mui): migrate Vozidla (Vehicles) page onto MUI kit`; + trailer).
+- [ ] **Step 4: MANUAL (USER, dev server) — deferred:** list renders (dense, mono numerics, inactive dimmed); status chip toggles active/inactive; add/edit modal validates (SPZ/Název required) + saves; SPZ uppercases; delete confirm works; empty state; permission gate; dark + light; no console errors.
+
+---
+
+## Task 5: Phase-2 verification + final review
+
+- [ ] **Step 1:** `npx tsc -b --noEmit` clean; `npm run build` (server+client); `npx vitest run` (148).
+- [ ] **Step 2:** Final whole-Phase-2 code review (kit components + Vozidla migration; behavior parity vs the original Vehicles.tsx).
+- [ ] **Step 3:** finishing-a-development-branch (merge to master after the user's visual check).
+
+---
+
+## Self-review notes (for the controller)
+
+- **Spec coverage:** §5 kit (Modal, ConfirmDialog, DataTable, field controls — Tasks 1–3), §5.1 dense DataTable (Task 2), §8 Phase 2 Vozidla pilot (Task 4). Pages still import only from `ui/`.
+- **Parity risks:** Vozidla validation (`Zadejte SPZ`/`Zadejte název`) + SPZ uppercasing + the three mutations' invalidate keys (`["vehicles","trips"]`) must be preserved verbatim. The status-toggle was a button styled as a badge → now a clickable `Chip`; behavior (toggle active) identical. `Modal`'s `onClose` is disabled while `loading` (matches FormModal's guard).
+- **No CSS file to delete:** Vozidla uses shared classes (forms/tables/buttons/components.css), not a `vehicles.css`; those shared files remain for not-yet-migrated pages. This page simply stops using them.
+- **Deferred:** all live visual checks (no dev server in implementer scope).

+# MUI Migration — Phase 3: Kit Expansion — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: superpowers:subagent-driven-development (or direct execution with gates). Steps use checkbox (`- [ ]`) syntax.
+
+**Goal:** Build the reusable `src/admin/ui/` components the page migrations keep needing, so later phases are fast and consistent. No page is migrated in this phase; the dev-only `/ui-kit` route is extended to showcase + visually verify each new component.
+
+**Why these (scout reuse counts):** `Select` ~34 pages, `Tabs` ~41 files, `StatusChip` ~34, plus paginated/sortable lists, dates, checkboxes, inline alerts.
+
+**Tech Stack:** MUI v7 (`@mui/material`) + `@mui/x-date-pickers` v8 + `date-fns` (cs locale) + Emotion. TypeScript strict.
+
+**Gates:** `npx tsc -b --noEmit`, `npm run build`, `npx vitest run` (148). Visual check (`/ui-kit`) is the user's. No dev server started by implementers.

+
+## Task 1: `Select`, `StatusChip`, `CheckboxField`, `Alert` (simple wrappers)
+
+**Files:** Create the four files; modify `index.ts`.

+- [ ] **Step 1: `Select.tsx`**
+
+```tsx
+import MuiTextField, { type TextFieldProps } from "@mui/material/TextField";
+import MenuItem from "@mui/material/MenuItem";

+            </MenuItem>
+          ))
+        : children}
+    </MuiTextField>
+  );
+}
+```
+
+- [ ] **Step 2: `StatusChip.tsx`**
+
+```tsx
+import Chip, { type ChipProps } from "@mui/material/Chip";
+
+type Props = Omit<ChipProps, "color"> & {
+  color?: "default" | "success" | "error" | "warning" | "info";

+      sx={{ fontWeight: 600, ...(onClick ? { cursor: "pointer" } : {}), ...sx }}
+      {...props}
+    />
+  );
+}
+```
+
+- [ ] **Step 3: `Checkbox.tsx`**
+
+```tsx
+import FormControlLabel from "@mui/material/FormControlLabel";
+import MuiCheckbox from "@mui/material/Checkbox";
+
+export function CheckboxField({
+  label,
+  checked,
+  onChange,

+      label={label}
+    />
+  );
+}
+```
+
+(Import `React` type or use `import type { ReactNode } from "react"` and type `label: ReactNode`.)
+
+- [ ] **Step 4: `Alert.tsx`**
+
+```tsx
+import type { ReactNode } from "react";
+import MuiAlert from "@mui/material/Alert";
+
+export default function Alert({
+  severity = "info",

+  return (
+    <MuiAlert severity={severity} onClose={onClose} sx={{ borderRadius: 2 }}>
+      {children}
+    </MuiAlert>
+  );
+}
+```
+
+- [ ] **Step 5:** export from `index.ts`: `Select` (+ `type SelectOption`), `StatusChip`, `{ CheckboxField }`, `Alert`.
+- [ ] **Step 6: Verify** `tsc -b` clean, `build:client` OK. **Commit** (`feat(mui): kit — Select, StatusChip, CheckboxField, Alert`; + trailer).
+
+---
+
+## Task 2: `Tabs` + `TabPanel`, `Pagination`
+
+**Files:** Create `Tabs.tsx`, `Pagination.tsx`; modify `index.ts`.
+
+- [ ] **Step 1: `Tabs.tsx`**
+
+```tsx
+import type { ReactNode } from "react";
+import MuiTabs from "@mui/material/Tabs";
+import Tab from "@mui/material/Tab";
+import Box from "@mui/material/Box";
+
+export interface TabDef {
+  value: string;
+  label: string;
+}
+
+export function Tabs({
+  value,
+  onChange,
+  tabs,

+    >
+      {tabs.map((t) => (
+        <Tab key={t.value} value={t.value} label={t.label} />

+  current: string;
+  children: ReactNode;
+}) {
+  if (value !== current) return null;
+  return <Box sx={{ pt: 2.5 }}>{children}</Box>;
+}
+```
+
+- [ ] **Step 2: `Pagination.tsx`**
+
+```tsx
+import Box from "@mui/material/Box";
+import MuiPagination from "@mui/material/Pagination";
+
+export default function Pagination({
+  page,
+  pageCount,
+  onChange,
+}: {

+        color="primary"
+        shape="rounded"
+      />
+    </Box>
+  );
+}
+```
+
+- [ ] **Step 3:** export `{ Tabs, TabPanel }` (+ `type TabDef`) and `Pagination` from `index.ts`.
+- [ ] **Step 4: Verify** `tsc -b` clean, `build:client` OK. **Commit** (`feat(mui): kit — Tabs/TabPanel + Pagination`; + trailer).
+
+---
+
+## Task 3: Sortable `DataTable`
+
+**Files:** Modify `src/admin/ui/DataTable.tsx`.
+
+- [ ] **Step 1:** Extend the types:
+  - `DataColumn<T>`: add `sortKey?: string;`
+  - `DataTableProps<T>`: add `sortBy?: string; sortDir?: "asc" | "desc"; onSort?: (key: string) => void;`
+- [ ] **Step 2:** In the header cell render, if `c.sortKey && onSort` is set, wrap the header in `TableSortLabel`:
+
+```tsx
+import TableSortLabel from "@mui/material/TableSortLabel";
+// ...header cell:
+{
+  c.sortKey && onSort ? (
+    <TableSortLabel
+      active={sortBy === c.sortKey}
+      direction={sortBy === c.sortKey ? (sortDir ?? "asc") : "asc"}
+      onClick={() => onSort(c.sortKey!)}
+    >
+      {c.header}
+    </TableSortLabel>
+  ) : (
+    c.header
+  );
+}
+```
+
+Non-sortable columns (no `sortKey`) render the plain header (unchanged). The existing `bold`/`mono`/`align`/`rowInactive`/`empty` behavior is untouched.
+
+- [ ] **Step 3: Verify** `tsc -b` clean, `build:client` OK, `vitest run` (148). **Commit** (`feat(mui): kit — sortable DataTable headers (TableSortLabel)`; + trailer).
+
+---
+
+## Task 4: `DateField` + LocalizationProvider
+
+**Files:** Create `src/admin/ui/DateField.tsx`; modify `MuiProvider.tsx`, `index.ts`.
+
+- [ ] **Step 1: Add `LocalizationProvider` to `MuiProvider.tsx`** wrapping its children, so date pickers work everywhere:
+
+```tsx

+
+> Verify the exact adapter import path for the installed `@mui/x-date-pickers@8` against its docs (it may be `@mui/x-date-pickers/AdapterDateFns` rather than `...V3`). Pick the one that resolves; report which.
+
+- [ ] **Step 2: `DateField.tsx`** — string-in / string-out (`yyyy-MM-dd`) to match existing form state:
+
+```tsx
+import { DatePicker } from "@mui/x-date-pickers/DatePicker";
+import { parseISO, format, isValid } from "date-fns";
+
+export default function DateField({
+  value,
+  onChange,
+  ...props
+}: { value: string; onChange: (v: string) => void } & Record<string, unknown>) {
+  const dateValue = value ? parseISO(value) : null;
+  return (
+    <DatePicker
+      value={dateValue && isValid(dateValue) ? dateValue : null}
+      onChange={(d) => onChange(d && isValid(d) ? format(d, "yyyy-MM-dd") : "")}
+      format="dd.MM.yyyy"
+      slotProps={{ textField: { size: "small", fullWidth: true } }}
+      {...props}
+    />
+  );
+}
+```
+
+- [ ] **Step 3:** export `DateField` from `index.ts`.
+- [ ] **Step 4: Verify** `tsc -b` clean, `build:client` OK. **Commit** (`feat(mui): kit — DateField over MUI X + cs LocalizationProvider`; + trailer).
+
+---
+
+## Task 5: Extend `/ui-kit` showcase + final review
+
+**Files:** Modify `src/admin/pages/UiKit.tsx`.
+
+- [ ] **Step 1:** Add a section rendering each new component with sample data, in the existing `ScopedCssBaseline` page: a `Select` (3 options), `StatusChip`s (each color), `Tabs`+`TabPanel` (2 tabs), `Pagination` (page 2 of 5), `CheckboxField`, `Alert` (one of each severity), a sortable `DataTable` (3 columns, one `sortKey`, local sort state), and a `DateField`.
+- [ ] **Step 2: Verify** `tsc -b` clean, `npm run build` (server+client) OK, `npx vitest run` (148). **Commit** (`feat(mui): showcase new kit components in /ui-kit`; + trailer).
+- [ ] **Step 3:** Final review of all new components (parallel/adversarial), then finishing-a-development-branch after the user's `/ui-kit` visual check.
+
+---
+
+## Self-review notes
+
+- All new components compose with the existing `Field` (Select/DateField are inputs; Field provides the label) and follow the size=small/outlined/fullWidth defaults.
+- `DataTable` sort is **additive** — existing callers (Vehicles) are unaffected (no `sortKey`/`onSort` → plain headers).
+- `DateField` is string-in/string-out so it drops into existing form state (`start_date: ""`), and uses cs locale + `dd.MM.yyyy` (matching the date convention in CLAUDE.md).
+- Deferred: `Autocomplete`, `FilterBar` — built when warehouse/list pages are migrated.

+# MUI Migration — Phase 4: Users (Uživatelé) — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: superpowers:subagent-driven-development. Steps use checkbox (`- [ ]`) syntax.
+
+**Goal:** Migrate `src/admin/pages/Users.tsx` onto the MUI kit, mirroring the already-migrated `Vehicles.tsx`, preserving ALL data logic. Presentation only changes.
+
+**Tech Stack:** MUI v7 kit (`src/admin/ui/`): `Button`, `Card`, `DataTable`, `Modal`, `ConfirmDialog`, `Field`, `TextField`, `SwitchField`, **`Select`** (new), **`StatusChip`** (new). MUI `Avatar`/`IconButton` used directly (as Vehicles uses `IconButton`).
+
+**Reference:** `src/admin/pages/Vehicles.tsx` is the canonical migrated page — copy its structure (Box + motion.div header, `Button startIcon`, `Card` + `DataTable`, `Modal` with `Field`/`TextField`, `ConfirmDialog`). The Users data layer already exists; do not change it.
+
+**Gates:** `npx tsc -b --noEmit`, `npm run build`, `npx vitest run` (148). Visual check (dev server) is the user's.
+
+---
+
+## Behavior to preserve VERBATIM (from the scout)
+
+- **Three mutations + invalidation:** `USER_INVALIDATE = ["users","trips","attendance","leave-requests","leave","projects"]`. `saveUser` (PUT if `editingUser` else POST), `deleteUser` (DELETE), `toggleUser` (PUT `{id,is_active}`). Keep all `onSuccess` messages.
+- **Self-edit AuthContext sync (critical):** in `saveUser.onSuccess`, when `editingUser && currentUser && Number(editingUser.id)===Number(currentUser.id)`, call `updateUser({ username, email, fullName: \`${first_name} ${last_name}\`.trim() })`. Then `setShowModal(false); setEditingUser(null);`then`await new Promise(r=>setTimeout(r,300))` **(intentional delay — keep it)** before the success toast.
+- **Auth guard:** `const { user: currentUser, updateUser, hasPermission } = useAuth();` → `if (!hasPermission("users.view")) return <Forbidden/>;`
+- **Self-protection:** the delete action is **hidden** and the status toggle is **disabled** when `user.id === currentUser?.id`. These reference the live `currentUser` — keep them in the column render closures.
+- **Password:** required only on create (`!editingUser`); empty string on edit means "keep existing".
+- **Role dropdown:** options from `roleListOptions()` query; default to `roles[0]?.id` on create. `role_id` is `number|string` in form state.
+- **`FormData` shape:** `{ username, email, password, first_name, last_name, role_id, is_active }`.
+
+---
+
+## Task 1: Migrate `Users.tsx`
+
+**Files:** Modify `src/admin/pages/Users.tsx` (read it first; it's the source of truth for the logic above).
+
+- [ ] **Step 1: Read** `src/admin/pages/Users.tsx` fully and `src/admin/pages/Vehicles.tsx` (the template). Keep ALL hooks, mutations, state, handlers, and the guard exactly; change only the rendered JSX.
+
+- [ ] **Step 2: Imports** — from `../ui`: `Button, Card, DataTable, Modal, ConfirmDialog, Field, TextField, SwitchField, Select, StatusChip, type DataColumn`. From `@mui/material`: `Box, Typography, Avatar, IconButton`. Keep `motion` (framer-motion), `useQuery`, `roleListOptions`, `useApiMutation`, `useAlert`, `useAuth`, `Forbidden`. **Remove** old imports: `FormModal`, `ConfirmModal`, `FormField`.
+
+- [ ] **Step 3: Page shell** — mirror Vehicles: outer `Box`; `motion.div` header (`Typography variant="h4"` "Správa uživatelů" + `Button startIcon={PlusIcon}` "Přidat uživatele"); `motion.div` + `Card` wrapping the `DataTable`. Loading state keeps the `admin-spinner` markup.
+
+- [ ] **Step 4: DataTable columns** (`DataColumn<User>[]`, defined inside the component so they close over `currentUser`/handlers):
+  - **Uživatel:** composite render — MUI `Avatar` (initial of `full_name`/`username`, `bgcolor:"primary.main"`) + name (`Typography`) + `@username` (`Typography variant="caption" color="text.secondary"`).
+  - **Email:** `render: (u) => u.email`.
+  - **Role:** `StatusChip` colored by role — map `"admin"` → `color="warning"`, else `"default"`; label = `roleDisplay`/role name.
+  - **Stav:** clickable `StatusChip` (`color={u.is_active?"success":"default"}`, `onClick` → `toggleActive(u)`), but **non-clickable / no onClick when `u.id===currentUser?.id`** (self-protection).
+  - **Akce:** `IconButton` edit (always); `IconButton` delete (`color="error"`) **only when `u.id !== currentUser?.id`**. Use the same edit/delete SVGs as Vehicles.
+
+- [ ] **Step 5: Add/Edit `Modal`** — `Field` + kit `TextField` for username/email/first_name/last_name; password `TextField type="password"` (label notes optional on edit); **`Select`** (inside a `Field` label="Role") for `role_id` with `options` from the roles query (`value: String(r.id), label: r.display_name||r.name`) — note `Select` is string-based, so store/compare `role_id` as string or `String(...)` at the boundary; `SwitchField` for `is_active`. Add a local `errors` state + validation in `handleSubmit` (required: username, email, first_name, last_name; password required when `!editingUser`) mirroring Vehicles, before `saveUser.mutateAsync`.
+
+- [ ] **Step 6: Delete `ConfirmDialog`** — drop-in replacement for `ConfirmModal` (title "Smazat uživatele", message with the user's name, `confirmVariant="danger"`).
+
+- [ ] **Step 7: Verify** `npx tsc -b --noEmit` clean; `npm run build` OK; `npx vitest run` (148). Drop all `admin-*` class names.
+
+- [ ] **Step 8: Commit** (`feat(mui): migrate Users (Uživatelé) page onto MUI kit`; + `Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>` trailer).
+
+- [ ] **Step 9: MANUAL (USER, dev server) — deferred:** list renders (avatar/role/status); status toggle works + is disabled for self; delete hidden for self; add (password required) + edit (password optional, role Select) save; self-edit updates the sidebar name; validation; dark+light; no console errors.
+
+---
+
+## Task 2: Review + finish
+
+- [ ] Spec-compliance review (esp. the self-edit AuthContext sync, self-protection, password-on-create-only, role Select string boundary, USER_INVALIDATE) then code-quality review.
+- [ ] finishing-a-development-branch after the user's visual check.
+
+---
+
+## Self-review notes
+
+- The role `Select` is string-based (per the Phase 3 review fix); convert `role_id` at the boundary (`String(r.id)` for options/value; the server accepts the string or coerce on submit if the API needs a number — check how the existing code sends it and match).
+- Self-protection guards and the self-edit `updateUser` sync are the highest-risk items — the spec reviewer must confirm both survive the column-render refactor.
+- No `users.css` exists; Users uses shared classes — nothing to delete, it just stops using them.

+# MUI Migration — Phase 5: Projects (Projekty) — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: superpowers:subagent-driven-development. Steps use checkbox (`- [ ]`) syntax.
+
+**Goal:** Migrate `src/admin/pages/Projects.tsx` onto the MUI kit. It's a **paginated, server-sorted list** with a create modal (customer/user `Select`s, `DateField`s, multiline notes) and a delete confirm that has an extra "delete files from disk" checkbox. Mirror `Vehicles.tsx`/`Users.tsx`; preserve ALL data logic.
+
+**Prereq kit tweak (Task 1):** `ConfirmDialog` needs to accept optional extra content below the message (for the delete-files checkbox), since `message` is a string.
+
+**Tech Stack:** MUI v7 kit (`src/admin/ui/`): `Button, Card, DataTable` (now sortable), `Pagination`, `Modal, ConfirmDialog, Field, TextField, Select, DateField, StatusChip, CheckboxField, type DataColumn`. MUI `Box/Typography/IconButton` direct.
+
+**Reference:** `Vehicles.tsx` + `Users.tsx` (migrated). The Projects data layer is authoritative — keep it.
+
+**Gates:** `npx tsc -b --noEmit`, `npm run build`, `npx vitest run` (148). Visual check is the user's.
+
+---
+
+## Behavior to preserve VERBATIM (from the scout)
+
+- **List state:** `const { sort, order, handleSort, activeSort } = useTableSort("project_number")`; `search`/`page` state; **reset `setPage(1)` when search changes**. `usePaginatedQuery<Project>(projectListOptions({ search, sort, order, page }))` → `{ items, pagination, isPending, isFetching }`.
+- **isFetching dimming:** the list Card gets `sx={{ opacity: isFetching ? 0.6 : 1, transition: "opacity .2s" }}`.
+- **Create-only** (edit navigates to the `/projects/:id` detail route — NOT a modal). `createForm = { name, customer_id, responsible_user_id, status: "aktivni", start_date, end_date, notes }`, `createErrors`, `creating`. Dependent queries enabled only while the modal is open: `offerCustomersOptions()`, `userListOptions("projects.view")` (filter to `is_active`), `projectNextNumberOptions()`. `createMutation`: POST `/projects`, `invalidate: ["projects","orders","offers","invoices","attendance"]`, onSuccess close + "Projekt byl vytvořen". **Validation: only `name` required ("Zadejte název projektu").**
+- **Delete:** `deleteTarget`/`deleteFiles` state. `deleteMutation`: DELETE `/projects/:id`, `invalidate: ["projects","warehouse","orders","offers","invoices","attendance"]`, called as `mutateAsync({ id, delete_files: deleteFiles })`, onSuccess toast `data?.message || "Projekt byl smazán"` + reset.
+- **Permissions:** `projects.view` → `<Forbidden/>`; `projects.create` hides the add button; `projects.delete` hides the per-row delete; delete also hidden when `p.order_id` (order-linked projects can't be manually deleted).
+- **Status constants:** `STATUS_LABELS = { aktivni:"Aktivní", dokonceny:"Dokončený", zruseny:"Zrušený" }`. Map to `StatusChip` colors: `aktivni`→`success`, `dokonceny`→`info`, `zruseny`→`default`.
+- **Next number:** `nextNumberQuery.data?.number ?? nextNumberQuery.data?.next_number ?? "…"`.
+
+---
+
+## Task 1: Extend `ConfirmDialog` with optional extra content
+
+**Files:** Modify `src/admin/ui/ConfirmDialog.tsx`.
+
+- [ ] **Step 1:** Add `children?: ReactNode` to `ConfirmDialogProps` (import `type { ReactNode }`). Render it in `DialogContent` BELOW the message (live — not frozen, so the checkbox stays interactive):
+
+```tsx
+<DialogContent>
+  <DialogContentText>{shown.message}</DialogContentText>
+  {children}
+</DialogContent>
+```
+
+- [ ] **Step 2:** Verify `tsc -b` clean; `build:client` OK; existing callers (Vozidla, Users) unaffected (no `children` → unchanged). **Commit** (`feat(mui): ConfirmDialog optional children (extra content below message)`; + trailer).
+
+---
+
+## Task 2: Migrate `Projects.tsx`
+
+**Files:** Modify `src/admin/pages/Projects.tsx` (read it first — authoritative for the logic above).
+
+- [ ] **Step 1: Read** `src/admin/pages/Projects.tsx` fully + `Users.tsx`/`Vehicles.tsx`. Keep ALL hooks/queries/mutations/handlers/permission-guards/state. Change only presentation.
+
+- [ ] **Step 2: Imports** — from `../ui`: `Button, Card, DataTable, Pagination, Modal, ConfirmDialog, Field, TextField, Select, DateField, StatusChip, CheckboxField, type DataColumn`. MUI `Box, Typography, IconButton` direct. Keep `motion`, `useNavigate`, the query options, `useApiMutation`, `useAlert`, `useAuth`, `Forbidden`. Remove `FormModal`/`ConfirmModal`/`FormField`/`AdminDatePicker`/legacy `Pagination` imports.
+
+- [ ] **Step 3: Page shell** — Box + motion.div header (`Typography variant="h4"` "Projekty" + `Button startIcon={PlusIcon}` "Nový projekt", hidden without `projects.create`). A search `TextField` (no `Field` wrapper) that sets search + `setPage(1)`.
+
+- [ ] **Step 4: List** — `Card` (with the `isFetching` opacity sx) wrapping a sortable `DataTable<Project>`:
+  - Wire sort: `sortBy={sort} sortDir={order} onSort={handleSort}`. Give sortable columns a `sortKey` (e.g. `project_number`, `name` — match the server's accepted sort keys from the original `SortIcon` usage).
+  - Columns: project number (`mono`, `sortKey`), name (`sortKey`), customer, responsible user, status (`StatusChip` per the color map), linked order number (if `order_id`), start/end dates (`mono`, via the existing date formatter), actions — a detail link/`IconButton` that `navigate(\`/projects/${p.id}\`)`for edit, and a delete`IconButton color="error"`shown only when`hasPermission("projects.delete") && !p.order_id`.
+  - Below the table: `<Pagination page={page} pageCount={pagination?.totalPages ?? 1} onChange={setPage} />` (use the actual page-count field from `pagination` — check the shape).
+
+- [ ] **Step 5: Create `Modal`** (`isOpen={showCreate}`, `loading={creating}`, title "Nový projekt", subtitle/hint with the next number): `Field`+`TextField` for name (required, error from `createErrors`); `Select` (in a `Field`) for customer (`offerCustomersOptions`) and responsible user (active users) — options `{ value: String(id), label }`, convert at the boundary; `Select` for status (the STATUS_LABELS options); two `DateField`s for start/end (string in/out — matches `createForm.start_date`); `TextField multiline minRows={3}` for notes. Validation: only name required.
+
+- [ ] **Step 6: Delete `ConfirmDialog`** — title "Smazat projekt", message with the project name, `confirmVariant="danger"`, and as **children** a `CheckboxField` "Smazat i soubory z disku" bound to `deleteFiles`. `onConfirm` calls the existing delete handler (`mutateAsync({ id, delete_files: deleteFiles })`).
+
+- [ ] **Step 7: Verify** `tsc -b` clean; `npm run build` OK; `npx vitest run` (148). Drop `admin-*` classes. (Projects has no own CSS file; it uses shared classes.)
+
+- [ ] **Step 8: Commit** (`feat(mui): migrate Projects (Projekty) page onto MUI kit`; + trailer).
+
+- [ ] **Step 9: MANUAL (USER) — deferred:** list renders + sorts (click headers) + paginates + dims while fetching; create modal (customer/user/status selects, date pickers, notes; name-required validation; next number shown) saves; delete confirm with the files checkbox works; order-linked projects show no delete; permission gating; dark+light.
+
+---
+
+## Task 3: Review + finish
+
+- [ ] Spec-compliance review (server sort/pagination wiring, the create `invalidate` arrays, name-only validation, delete `{id, delete_files}` body + the checkbox, permission/order-link gating, status color map, the Select string boundaries) → code-quality review.
+- [ ] finishing-a-development-branch after the user's visual check.
+
+---
+
+## Self-review notes
+
+- This is the first page to exercise the **sortable DataTable** + **Pagination** + **DateField** + **Select** together — confirm the sort keys match what the server accepts and the pagination page-count field name is correct (read the query options / a working paginated page).
+- `Select` is string-based; convert customer/user/status ids at the form boundary (`String(...)` for options/value; send what the server expects).
+- The delete-files checkbox rides in `ConfirmDialog` `children` (Task 1) — it's live (not frozen), so it toggles while open; it resets via the caller on close.
+- Edit is a route navigation (`/projects/:id`), NOT a modal — don't add an edit modal.

+# Bulk Plan Creation Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Assign one project/category to many employees over a date range in a single action ("Hromadné přiřazení" on /plan-work).
+
+**Architecture:** A new `POST /api/admin/plan/entries/bulk` endpoint drives a `bulkCreateEntries` service that, per employee, computes the eligible days in the range (weekday filter + Feature A's under-cap rule), groups contiguous eligible days into runs, and creates one range `work_plan_entries` row per run by **reusing `createEntry`**. The frontend adds a presentational `BulkPlanModal` (mirroring the single-create form + the existing bulk-attendance employee picker) wired from `PlanWork`, with a summary alert and `["plan"]` invalidation. No DB migration.
+
+**Tech Stack:** Fastify 5 + Prisma (MySQL), Zod 4, React 18 + MUI v7, TanStack Query, Vitest (server-side, real test DB). Spec: `docs/superpowers/specs/2026-06-08-bulk-plan-creation-design.md`. Builds on Feature A (multi-record plan cells, v2.0.5).
+
+**Gates:** `npx tsc -b --noEmit`, `npm run build`, `npx vitest run`. The frontend has no component-test harness (server-side tests only), so Task 2 gates on `tsc -b` + `build`.
+
+---
+
+## File Structure
+
+**Backend**
+
+- `src/schemas/plan.schema.ts` — add `BulkPlanEntrySchema`.
+- `src/services/plan.service.ts` — add `bulkCreateEntries(...)` (reuses `createEntry`, `assertNotPastDate`, `assertActiveCategory`, `toDateOnly`, `MAX_RECORDS_PER_CELL`).
+- `src/routes/admin/plan.ts` — add `POST /entries/bulk`.
+
+**Frontend**
+
+- `src/admin/components/BulkPlanModal.tsx` — new presentational modal.
+- `src/admin/hooks/usePlanWork.ts` — add a `bulkCreate` mutation.
+- `src/admin/pages/PlanWork.tsx` — toolbar button + bulk form state + toggles + submit wiring.
+
+**Tests**
+
+- `src/__tests__/plan.test.ts` — `bulkCreateEntries` service tests.
+
+---
+
+## Task 1: Backend — bulk endpoint + service

+**Files:**

+- Modify: `src/schemas/plan.schema.ts`
+- Modify: `src/services/plan.service.ts`

+
+- [ ] **Step 1: Write the failing service tests**
+
+Add this block to the end of `src/__tests__/plan.test.ts` (before the final HTTP describe block is fine; anywhere at top level). It imports `bulkCreateEntries` — add it to the existing `import { ... } from "../services/plan.service"` list at the top of the file.

+- [ ] **Step 4: Run the service tests to verify they pass**
+
+Run: `npx vitest run src/__tests__/plan.test.ts`
+Expected: PASS (including the 5 new bulk tests).
+
+- [ ] **Step 5: Add `BulkPlanEntrySchema` to `plan.schema.ts`**
+
+Append to `src/schemas/plan.schema.ts`:
+
+```ts
+export const BulkPlanEntrySchema = z
+  .object({
+    user_ids: z
+      .array(intFromForm)

+  .refine((v) => v.date_to >= v.date_from, {
+    message: "Datum do musí být stejné nebo po datumu od",
+    path: ["date_to"],
+  });
+```
+
+- [ ] **Step 6: Add the `POST /entries/bulk` route**
+
+In `src/routes/admin/plan.ts`: add `bulkCreateEntries` to the existing import from `../../services/plan.service` and `BulkPlanEntrySchema` to the import from `../../schemas/plan.schema`. Then add this route immediately after the `POST /entries` handler (after its closing `);`, before `PATCH /entries/:id`):
+
+```ts
+// --- POST /plan/entries/bulk ---
+app.post(
+  "/entries/bulk",
+  { preHandler: requirePermission("attendance.manage") },
+  async (request: FastifyRequest, reply: FastifyReply) => {
+    const body = parseBody(BulkPlanEntrySchema, request.body);
+    if ("error" in body) return error(reply, body.error, 400);
+    const result = await bulkCreateEntries(
+      body.data!,
+      request.authData!.userId,
+    );
+    if ("error" in result) return error(reply, result.error, result.status);
+    await logAudit({
+      request,
+      authData: request.authData,
+      action: "create",
+      entityType: "work_plan_entry",
+      description: `Hromadné přiřazení: ${body.data!.category} — ${result.data.users} zaměstnanců, ${body.data!.date_from}–${body.data!.date_to} (${result.data.created_days} dní)`,
+    });
+    return success(reply, result.data, 201, "Hromadné přiřazení dokončeno");
+  },
+);
+```
+
+- [ ] **Step 7: Add an HTTP route test**
+
+Add to the `describe("HTTP /api/admin/plan", ...)` block in `src/__tests__/plan.test.ts`:
+
+```ts
+it("POST /entries/bulk requires attendance.manage", async () => {
+  const res = await authPost("/api/admin/plan/entries/bulk", noPermToken, {
+    user_ids: [adminUserId],
+    date_from: "2095-06-01",
+    date_to: "2095-06-01",
+    include_weekends: true,
+    category: "work",
+    note: `${N}bulk-forbidden`,
+  });
+  expect(res.statusCode).toBe(403);
+});
+
+it("POST /entries/bulk creates entries for an admin and returns a summary", async () => {
+  const res = await authPost("/api/admin/plan/entries/bulk", adminToken, {
+    user_ids: [adminUserId],
+    date_from: "2095-06-05", // Sunday; weekends on → 1 day
+    date_to: "2095-06-05",
+    include_weekends: true,
+    category: "work",
+    note: `${N}bulk-http`,
+  });
+  expect(res.statusCode).toBe(201);
+  const body = res.json();
+  expect(body.success).toBe(true);
+  expect(body.data.created_days).toBe(1);
+  expect(body.data.users).toBe(1);
+});
+```
+
+- [ ] **Step 8: Gate**
+
+Run: `npx tsc -b --noEmit` (exit 0), then `npx vitest run` (all pass).
+
+- [ ] **Step 9: Commit**
+
+```bash
+git add src/schemas/plan.schema.ts src/services/plan.service.ts src/routes/admin/plan.ts src/__tests__/plan.test.ts
+git commit -m "feat(plan): bulk entry creation endpoint + service"

+
+- [ ] **Step 2: Add a `bulkCreate` mutation to `usePlanWork.ts`**
+
+After the `deleteOverride` mutation definition (before the `rollbackMutation` function), add:
+
+```ts
+const bulkCreate = useMutation({
+  mutationFn: (body: any) =>
+    apiCall("/api/admin/plan/entries/bulk", {
+      method: "POST",
+      body: JSON.stringify(body),
+      headers: { "Content-Type": "application/json" },
+    }),
+  onSuccess: () => {
+    // No optimistic patch — bulk can touch many cells; just invalidate and
+    // let the grid refetch the authoritative state.
+    invalidate();
+  },
+});
+```
+
+Add `bulkCreate` to the hook's return object (next to `createEntry`, etc.).
+
+- [ ] **Step 3: Wire the bulk modal into `PlanWork.tsx`**
+
+(a) Add imports near the other component imports:
+
+```ts
+import BulkPlanModal, { type BulkPlanForm } from "../components/BulkPlanModal";
+```
+
+(b) Pull `bulkCreate` out of the `usePlanWork(...)` destructure (alongside `createEntry`, etc.).
+
+(c) Add bulk state + a default form (place near the other `useState` declarations, after `catModalOpen`):
+
+```ts
+const [bulkOpen, setBulkOpen] = useState(false);
+const [bulkSubmitting, setBulkSubmitting] = useState(false);
+const [bulkForm, setBulkForm] = useState<BulkPlanForm>(() => {
+  const today = todayIsoLocal();
+  return {
+    date_from: today,
+    date_to: today,
+    is_range: false,
+    user_ids: [],
+    include_weekends: false,
+    project_id: "",
+    category: "work",
+    note: "",

+(e) Render the modal alongside `<PlanCategoriesModal ... />`:
+
+```tsx

+/>
+```
+
+- [ ] **Step 4: Gate + Chrome check**
+
+```bash
+npx tsc -b --noEmit
+npm run build
+```
+
+Then in Chrome on `/plan-work` (dev server already running — do not start it): click "Hromadné přiřazení", select 2 employees, a date range with "Více dní", leave weekends off, pick a project + category, submit; confirm the grid fills only Mon–Fri across the selected people, the summary alert shows counts, and re-running on a day already at 3 records skips it.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/admin/components/BulkPlanModal.tsx src/admin/hooks/usePlanWork.ts src/admin/pages/PlanWork.tsx
+git commit -m "feat(plan): bulk assignment modal on /plan-work"
+```
+

+
+## Task 3: Release v2.0.6
+
+**Files:**
+
+- Modify: `package.json`
+
+- [ ] **Step 1: Bump version** to `"version": "2.0.6"` in `package.json`.
+
+- [ ] **Step 2: Full gate**
+
+```bash
+npx tsc -b --noEmit
+npx vitest run
+npm run build
+```
+
+Expected: tsc exit 0, vitest all pass, build success.
+
+- [ ] **Step 3: Merge to master + commit + tag**
+
+```bash
+git checkout master
+git merge --ff-only feat/bulk-plan-creation
+git add package.json
+git commit -m "chore(release): v2.0.6 — bulk plan creation"
+git tag -a v2.0.6 -m "v2.0.6 — bulk plan creation"
+```
+
+(If implementation happened directly on master, skip the checkout/merge.)
+
+- [ ] **Step 4: Push to Gitea**
+
+```bash
+git push origin master
+git push origin v2.0.6
+```
+
+- [ ] **Step 5: Build tarball + deploy to production (REQUIRES explicit user confirmation)**
+
+```bash
+tar -czf app-ts-2.0.6.tar.gz dist dist-client prisma package.json package-lock.json scripts
+scp app-ts-2.0.6.tar.gz boha_admin@192.168.50.100:/tmp/
+ssh boha_admin@192.168.50.100 'set -e; cd /var/www/app-ts && rm -rf dist dist-client prisma scripts package.json package-lock.json && tar -xzf /tmp/app-ts-2.0.6.tar.gz && npm install --omit=dev && npx prisma migrate deploy && pm2 restart app-ts --update-env'
+```
+
+No migration ships in this release → `prisma migrate deploy` reports "No pending migrations".
+
+- [ ] **Step 6: Health check**
+
+```bash
+ssh boha_admin@192.168.50.100 'curl -s -o /dev/null -w "%{http_code}\n" http://127.0.0.1:3001/; curl -s -o /dev/null -w "%{http_code}\n" http://127.0.0.1:3001/api/admin/session'
+```
+
+Expected: `200` then `401`. Confirm pm2 shows `app-ts` v2.0.6 online.
+

+
+## Notes for the implementer
+
+- **Reuse, don't re-validate:** `bulkCreateEntries` calls `createEntry`, which already enforces the cap, past-date, category, and range checks. Don't duplicate those.
+- **`skipped_days` semantics:** only weekday-eligible days blocked by the cap count as skipped. Weekend days (when excluded) are out of scope, not skipped.
+- **No DB migration.** Don't run any prisma migrate command.
+- **Do not start the dev server** — the user runs it. Use the running instance for the Chrome check.
+- **Do not deploy to production without explicit confirmation** (Task 3, Steps 5–6).

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

+**Controller note (migration):** Tasks that touch the DB require the dev server stopped. After Task 1's files are written, the **controller** runs: ask user to stop dev server → `npx prisma generate` → `npx prisma migrate deploy` (applies to dev `app` DB) → resume. Backend tsc is red between Task 1 and Task 2 (data model changes before the service is updated) — that is expected; Task 2 restores green.
+

+
+## Task 1: Data model + migration
+

+
+  @@index([conversation_id, id], map: "idx_ai_chat_conv")
+}
+```
+
+- [ ] **Step 2: Write the migration SQL** at `prisma/migrations/20260608140000_add_ai_conversations/migration.sql`:
+
+```sql
+-- Multi-conversation Odin: conversations table + conversation_id on messages.
+

+```
+
+- [ ] **Step 3: Controller applies the migration** (not the implementer):
+  - Ask user to stop the dev server (Prisma engine DLL is locked on Windows otherwise).
+  - `npx prisma generate` — expect "Generated Prisma Client".
+  - `npx prisma migrate deploy` — expect "Applying migration `20260608140000_add_ai_conversations`" → "successfully applied".

+**Files:**
+
+- Modify: `src/services/ai.service.ts`
+- Modify: `src/schemas/ai.schema.ts`
+- Modify: `src/routes/admin/ai.ts`

+- [ ] **Step 2: Schemas** — in `src/schemas/ai.schema.ts`, keep `AiHistoryAppendSchema` (reused for append) and add:

+export const AiRenameConversationSchema = z.object({
+  title: z.string().min(1, "Název je povinný").max(255),
+});
+```
+
+- [ ] **Step 3: Routes** — in `src/routes/admin/ai.ts`: update imports (drop `getChatHistory/appendChatMessages/clearChatHistory`, add the new fns; add `AiCreateConversationSchema, AiRenameConversationSchema`; import `parseId` from `"../../schemas/common"`). Delete the three `/history` route blocks and append these (all `requirePermission("ai.use")`):
+
+```ts

+## Task 3: Backend tests
+
+**Files:**
+
+- Modify: `src/__tests__/ai.test.ts`
+
+- [ ] **Step 1: Replace the imports + cleanup markers.** Swap the history-fn imports for the conversation fns, and update the top-of-file constants/cleanup:
+
+```ts
+import {
+  computeCostUsd,
+  recordUsage,
+  getMonthSpendUsd,
+  getBudgetUsd,
+  assertBudgetAvailable,
+  isConfigured,
+  listConversations,

+
+const KIND = "test_ai";

+const CONV_UID_B = 999999992;
+const HIST_MARKER = "「test-conv」"; // marks HTTP-test conversations on real users
+```
+
+Update the top-level cleanup (`afterAll` and the conversation `beforeEach`) to delete by these. Deleting a conversation cascades its messages:
+
+```ts
+afterAll(async () => {
+  await prisma.ai_usage.deleteMany({ where: { kind: KIND } });
+  await prisma.ai_conversations.deleteMany({
+    where: { user_id: { in: [CONV_UID_A, CONV_UID_B] } },

+## Task 4: Frontend queries + types
+
+**Files:**

+- Modify: `src/admin/lib/queries/ai.ts`
+
+- [ ] **Step 1: Add conversation options.** Keep everything (incl. `aiHistoryOptions` for now — it's removed in Task 6 alongside its only consumer `DashAssistant.tsx`, so every task stays green). Add:
+
+```ts
+export interface Conversation {
+  id: number;
+  title: string;
+  updated_at: string;
+}
+
+export const aiConversationsOptions = () =>
+  queryOptions({
+    queryKey: ["ai", "conversations"],
+    queryFn: () =>
+      jsonQuery<{ conversations: Conversation[] }>(
+        "/api/admin/ai/conversations",
+      ),
+    staleTime: 30_000,
+  });
+
+export const aiConversationMessagesOptions = (id: number) =>
+  queryOptions({
+    queryKey: ["ai", "conversation", id, "messages"],
+    queryFn: () =>
+      jsonQuery<{ messages: StoredChatMessage[] }>(

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

+# CSS → MUI Migration — Design Spec
+
+**Date:** 2026-06-06
+**Status:** Approved design, pending implementation plan
+**Topic:** Replace hand-written CSS with MUI (Material UI), themed to the existing brand, with a modern "Soft-SaaS + dense tables" look, rolled out incrementally.
+
+---
+
+## 1. Goal
+
+Migrate the admin frontend off its ~7,100 lines of hand-written CSS onto **MUI (Material UI)** as the styling system, while simultaneously delivering a **modern visual refresh**. Dark/light theming and the existing design tokens are preserved (they already exist and work). The migration is **incremental and always shippable** — never a frozen big-bang.
+
+This is explicitly a **styling + component-layer migration**. Application behavior, data flow, API contracts, and business logic remain identical (one deliberate exception: modal accessibility — see §5 / §11). Backend code is not touched.
+
+---
+
+## 2. Current state (audit findings, 2026-06-06)
+
+The premise "we want dark/light mode" is largely **already met**. The audit found:
+
+- **19 CSS files, ~7,101 lines** under `src/admin/`. Largest: `components.css` (1,224), `plan.css` (1,152), `offers.css` (641), `layout.css` (582), `dashboard.css` (525), `forms.css` (510), `attendance.css` (455), `base.css` (411). Smallest: `responsive.css` (6 lines, effectively an empty placeholder). The token file `variables.css` (164) and `plan.css` are special-cased in §6.
+- **A complete CSS-variable token system** in `variables.css`: spacing scale, colors, radii, motion durations, fonts, safe-area insets.
+- **A full dark + light theme** via `[data-theme="dark"]` / `[data-theme="light"]`. The attribute is owned and written by **`src/context/ThemeContext.tsx`** (`useTheme()` / `toggleTheme()`, which calls `document.documentElement.setAttribute("data-theme", …)`). `Sidebar.tsx`, `AdminLayout.tsx`, and `Login.tsx` only **consume** it via `useTheme()`.
+- **Distinctive fonts already chosen:** Urbanist (headings), Plus Jakarta Sans (body), DM Mono (mono).
+- **Stack:** React 18.3, Vite 8, TypeScript (strict), TanStack Query v5, **framer-motion** (used broadly — see §9: modals, toasts, the AdminLayout logout transition, dashboard cards, Login), react-datepicker, react-quill-new, Leaflet, @dnd-kit. No Tailwind / MUI / Emotion direct deps; no PostCSS config (PostCSS ships only transitively under Vite).
+- **Type skew (pre-existing):** `react`/`react-dom` are `^18.3.1` but `@types/react`/`@types/react-dom` are `^19.x`. MUI's component types are sensitive to the `@types/react` major version — see §11 / §14.
+
+**Implication:** the migration is not about adding theming; it's about replacing the CSS plumbing and modernizing the look while carrying the existing tokens forward.
+
+---
+
+## 3. Locked decisions

+| Decision     | Choice                                                                                                                                               |

+| Goal         | Both — re-plumb CSS **and** modern visual refresh                                                                                                    |
+| Approach     | Component library (not a utility framework)                                                                                                          |
+| Library      | **MUI (Material UI)** — target **v7** + **MUI X v8** (pickers), themed to the brand                                                                  |
+| Look         | **"Soft-SaaS shell (B) + dense data tables (D)"** — airy modern chrome, dense efficient tables                                                       |
+| Theming      | Existing CSS-var tokens become the source; one `data-theme` attribute drives both MUI and legacy CSS (mechanism verified against MUI v7 docs — §4.1) |
+| Roll-out     | Incremental, foundation-first; each phase is one or more normal releases                                                                             |

+| Heavy tables | MUI `Table` styled dense, reusing existing `useTableSort` + `usePaginatedQuery` hooks (no DataGrid, no paid license)                                 |
+

+
+## 4. Architecture
+
+The tokens become the **single shared palette** that feeds both worlds during the migration, so migrated and unmigrated pages stay on the same colors/typography. Structure modernizes per page (see §7 for the token-level vs component-level split).
+
+```
+Tokens (colors, fonts, radii, motion, dark/light)   ← refreshed once, early
+      │   (identical palette feeds both sides)
+      ├───────────────►  legacy CSS  ── unmigrated pages        ┐
+      │                                                          ├─ coexist, same palette
+      └──►  MUI theme (createTheme + colorSchemes) ──────────────┘
+                 │
+                 ▼
+        Foundation UI kit  (src/admin/ui/*)  ──►  migrated pages
+```
+
+### 4.1 Theming bridge (`src/admin/theme.ts`)
+
+- One `theme.ts` builds the MUI theme from the tokens:
+  - **Palette:** `primary` = brand red (`#d63031` dark / `#c73030` light), plus `success`/`warning`/`error`/`info` mapped to existing semantic tokens.
+  - **Typography:** Urbanist for `h1–h6`, Plus Jakarta Sans for body, DM Mono for numeric/monospace contexts.
+  - **Shape/spacing:** `borderRadius` and spacing from the token scale.
+  - **`components` overrides:** the Soft-SaaS defaults (rounded cards, pill buttons, soft shadows, tinted chips) baked in so every MUI component is on-brand by default.
+- **Dark/light keeps the existing toggle (verified against MUI v7 docs).** MUI's CSS theme variables support a custom color-scheme selector that targets the existing attribute exactly:
+  ```ts
+  createTheme({
+    cssVariables: { colorSchemeSelector: "[data-theme='%s']" },
+    colorSchemes: { light: true, dark: true },
+    // …palette/typography/components
+  });
+  ```
+  This emits `[data-theme="light"]{…}` and `[data-theme="dark"]{…}`, matching the attribute `ThemeContext` already writes. One attribute drives MUI _and_ legacy CSS → no second toggle, 1:1 dark parity.
+- **One attribute owner.** `ThemeContext` remains the sole writer of `data-theme` on `<html>`. Its `toggleTheme()` must **also call MUI's `setMode()`** so MUI's internal color-scheme state stays in sync with the attribute. Do **not** also enable MUI's `InitColorSchemeScript` attribute-writing (avoid two writers). Wired in Phase 0.
+
+### 4.2 Coexistence (the safety mechanism)
+
+- Use MUI's **`ScopedCssBaseline`** around migrated page subtrees only, so MUI's CSS reset applies _inside_ migrated pages without disturbing unmigrated ones still on `base.css`. No global reset until teardown.
+- The `CssVarsProvider`/`ThemeProvider` must sit **above** every `ScopedCssBaseline`, and `data-theme` must live on a common ancestor (`<html>`, as today) so the `[data-theme='%s']` selector resolves inside scoped subtrees.
+- Styling engine: MUI default (**Emotion**). SPA only (Vite, no SSR), so no SSR-cache complexity.
+
+---
+
+## 5. Foundation UI kit (`src/admin/ui/`)
+
+**Principle: pages never import `@mui` directly.** A thin wrapper kit bakes in brand defaults and **keeps the current component APIs and Czech labels**, so migrating a page is mostly swapping imports, not rewriting logic, and tuning a default touches one file, not 57.
+
+| Today                                                  | → Foundation kit (`src/admin/ui/`)                                                                                                                                         | MUI base             |
+| ------------------------------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------- |
+| `FormModal` / `ConfirmModal`                           | `<Modal>` — preserves **FormModal's** full prop set (`submitDisabled`, `subtitle`, `loading`); ConfirmModal needs only `title`/`message`/`type`/`confirmVariant`/`loading` | `Dialog`             |
+| `.admin-table*` + `useTableSort` + `usePaginatedQuery` | **`<DataTable>`** (the dense "D" look)                                                                                                                                     | `Table`              |
+| `AdminDatePicker` (react-datepicker)                   | `<DatePicker>` — `cs` locale, `dd.MM.yyyy`                                                                                                                                 | MUI X Pickers (free) |
+| `.admin-btn`                                           | `<Button>` (pill / red-gradient default)                                                                                                                                   | `Button`             |
+| `.admin-form-*` inputs/selects                         | `<TextField>` / `<Select>` / `<Switch>`                                                                                                                                    | MUI form controls    |
+| `AlertContext` toasts                                  | `<Toast>` — keeps `useAlert()` API                                                                                                                                         | `Snackbar`           |
+| `AdminLayout` sidebar/topbar                           | `<AppShell>` — the soft-SaaS shell                                                                                                                                         | `Box` / `Drawer`     |
+| KPI tiles                                              | `<KpiCard>` / `<Card>`                                                                                                                                                     | `Card`               |
+| Tabs                                                   | `<Tabs>`                                                                                                                                                                   | `Tabs`               |
+
+**Modal behavior change (deliberate a11y gain — not a 1:1 match).** Today's modals use `useModalLock` (a ref-counted body-scroll lock, used in **8 places**, including non-`FormModal` spots like Dashboard, OfferDetail, ReceivedInvoices, WarehouseItemDetail) plus `role="dialog"`, but have **no focus trap, no initial-focus, no return-focus**. MUI `Dialog` adds scroll-lock _and_ a focus trap + return-focus. This is an intentional improvement; it is called out so it isn't a surprise. **Audit all 8 `useModalLock` call sites** — those not backed by `FormModal`/`ConfirmModal` either migrate to `<Modal>` or keep `useModalLock` until their page migrates. Verify stacked/nested modal scroll-lock still works.
+
+### 5.1 Dense `<DataTable>` (centerpiece)
+
+MUI `Table` styled to the compact "D" look — uppercase micro headers, **DM Mono right-aligned numerics**, tinted status `Chip`s, subtle row hover — wired to the **existing `useTableSort` (column sort) and `usePaginatedQuery` (list + pagination) hooks**. The current `.admin-table-responsive` horizontal-scroll wrapper carries over as MUI's `TableContainer`.
+
+- **Numbers stay formatted by the existing utilities.** Numeric/currency cells continue to render through `src/admin/utils/formatters.ts` (`formatCurrency` cs-CZ + `Kč`/`€`, `formatKm`, `czechPlural`). `<DataTable>` only _styles_ (DM Mono, right-align); it never re-formats values.
+- A mobile card-view variant for the densest tables is a future enhancement (out of scope for the first pass).
+
+### 5.2 Date pickers
+
+Swap `AdminDatePicker` → MUI X Date Pickers (free **Community** tier; only Range Pickers are Pro, which we don't need) with the `date-fns` adapter and **`cs` locale**. `AdminDatePicker` is used in **three variants**, all covered by Community:
+
+| Current (react-datepicker) | → MUI X                            | Format (date-fns tokens) |
+| -------------------------- | ---------------------------------- | ------------------------ |
+| date                       | `DatePicker`                       | `dd.MM.yyyy`             |
+| `showMonthYearPicker`      | `DatePicker` with month/year views | `MM/yyyy`                |
+| `showTimeSelectOnly`       | `TimePicker`                       | `HH:mm`                  |
+
+> **Format-token correction:** date-fns tokens are case-sensitive — `MM` = month, `mm` = minutes, `yyyy` = calendar year (`rrrr` = local-week-year, wrong). The format is **`dd.MM.yyyy`**, not `dd.mm.rrrr`. Apply via `LocalizationProvider` `dateFormats` (e.g. `{ keyboardDate: "dd.MM.yyyy" }`).
+
+Retires a custom component and the `react-datepicker` dependency; MUI's responsive picker handles touch/mobile.
+
+---
+
+## 6. CSS end-state (explicit)
+
+1. **Gone — ~90% of files (~80% of lines).** All per-feature CSS files deleted as their pages migrate: `buttons`, `forms`, `tables`, `invoices`, `offers`, `attendance`, `dashboard`, `warehouse`, `login`, `settings`, `filemanager`, `pagination`, `datepicker`, `layout`, `base`, `components`, **`responsive`** (the 6-line placeholder). What they expressed becomes the MUI theme + `sx`/`styled`.
+2. **Tokens move, don't die.** `variables.css` is rewritten into `theme.ts` (TypeScript). With MUI's CSS-variable mode, MUI emits those tokens as CSS custom properties at runtime — so the hand-written `variables.css` file is retired, but the values live on in TS as the single source.
+3. **Stays — a small residue** for the genuinely-bespoke widgets MUI does not provide:
+   - **Plan/gantt grid** (`plan.css`, ~1,152 lines, slimmed) — kept as a custom component with a trimmed stylesheet (largest survivor; ~16% of today's lines, hence "~80% of lines removed" not 90%).
+   - **Quill rich-text editor** and **Leaflet map** — kept, with small theming CSS.
+   - These surviving stylesheets reference the **MUI-emitted CSS variables**, so they stay in sync with the theme and dark/light.
+
+**Stated precisely:** custom React components stay (their logic is the value); standard ones are re-skinned via MUI and lose their custom CSS; styling comes from the MUI theme; the only custom CSS remaining is the slim stylesheets for the 3 bespoke widgets, which still read the MUI theme tokens. Literally-zero custom CSS would require rebuilding the plan grid from MUI primitives — explicitly **out of scope** (YAGNI).
+
+---
+
+## 7. Aesthetic spec ("Soft-SaaS + dense", validated 2026-06-06)
+
+The refresh is delivered in **two layers**, which is how it reconciles with the "shared palette" coexistence model:
+
+- **Token-level (palette) — applies app-wide, early.** These are small refinements to the existing tokens (e.g. light canvas `#f5f4f2 → #f4f3f1`, refined status-chip tints). They are updated once in `variables.css`/`theme.ts` in Phase 0, so **both** legacy and migrated pages share the refreshed palette. This means Phase 0 _does_ shift colors slightly app-wide — it is **not** visually a no-op — but layout/structure is unchanged.
+- **Component-level (the "modern look") — per page, via MUI.** The distinctive new look (red-gradient pill buttons, 16px soft-shadow rounded cards, the soft-SaaS shell, dense tables) is delivered through MUI component styling as each page migrates. Unmigrated pages keep their current structure on the refreshed palette.
+
+So §4's "coexist" promise is **same palette/typography, not pixel-identical structure**.
+
+Concrete values implementers must reproduce (light shown):
+
+- **Canvas:** `#f4f3f1`. **Surfaces/cards:** `#ffffff`, radius **16px**, soft shadow `0 6px 20px rgba(20,20,40,.06), 0 1px 2px rgba(0,0,0,.03)`.
+- **Sidebar:** transparent on canvas; active item = white pill with soft shadow + red text/icon.
+- **Top bar:** Urbanist 800 page title; pill search field; circular icon buttons; gradient avatar; primary action = red-gradient pill button.
+- **Primary button:** `linear-gradient(135deg,#e23a3a,#c01f1f)`, radius `999px`, shadow `0 5px 14px rgba(214,48,49,.32)`.
+- **Status chips:** pill, soft tinted — paid `#eafaf0`/`#2b8a3e`, overdue `#fdecec`/`#c92a2a`, draft `#fbf3dd`/`#92760b`.
+- **Dense table:** padding ~`.5rem 1rem`; headers `.64rem` uppercase, letter-spacing `.05em`, muted; **DM Mono** right-aligned numeric cells; row hover `#faf9f7`; row borders `#f5f3f1`; container is a 16px soft card.
+- **Fonts:** Urbanist 600–800 (headings), Plus Jakarta Sans 400–700 (body), DM Mono 400–500 (figures).
+
+**Dark mode.** Several §7 values are new and have no current dark counterpart, so dark is **authored in `theme.ts` during Phase 0** by deriving from these light values + the existing dark surfaces (canvas `#0a0a0a`/`#0f0f0f`, glass borders `rgba(255,255,255,.08)`, dark chip tints), not literally "mirrored."
+
+**Visual references** (persisted, gitignored): `.superpowers/brainstorm/9839-1780760811/content/` — `aesthetic-directions.html`, `refined-hybrid-faktury.html`.
+
+---
+
+## 8. Migration phasing
+
+Each phase is **one or more** normal `v1.x` releases (realistic total: ~a dozen releases). Each migrated page deletes its own CSS file.
+
+- **Phase 0 — Foundation.** Install MUI v7 + Emotion + MUI X v8 Pickers; reconcile `@types/react` with the React 18 runtime (§14); write `theme.ts` from tokens **and apply the token-level palette refresh app-wide** (§7); author the dark palette; wire `ScopedCssBaseline` + the `ThemeContext`↔`setMode()` sync; build the `src/admin/ui/` kit; add the **dev-only** `/ui-kit` showcase route (guarded by `import.meta.env.DEV`, tree-shaken from prod). Layout/structure unchanged; colors shift slightly app-wide. Deletes no per-page CSS yet.
+- **Phase 1 — `<AppShell>` (chrome).** Migrate sidebar/topbar/theme-toggle to the soft-SaaS shell. Every page _inside the AdminLayout route_ sits in the new frame; unmigrated content still uses its own CSS inside it. Retires most of `layout.css`. **Login is NOT touched here** — it is a sibling route outside `AdminLayout` (`AdminApp.tsx:100`) with its own full-screen layout; see Phase 3.
+- **Phase 2 — Pilot CRUD page (Vozidla / vehicles).** Full end-to-end: list, dense `<DataTable>`, filters, create/edit `<Modal>`. Battle-tests and tunes the foundation. Deletes that page's CSS.
+- **Phase 3 — Simple CRUD + Login.** Uživatelé (users), Projects, Settings, and **Login** (migrated standalone — keeps its own full-screen layout, theme toggle, and 2FA two-step + shake/animate-out flow; deletes `login.css`).
+- **Phase 4 — List-heavy** (Offers, Invoices lists). Hammers `<DataTable>`. Invoice/offer **on-screen detail** (Quill, the detail page) re-themed, not rebuilt. (Generated PDFs are out of scope — §13.)
+- **Phase 5 — Attendance & Leave/Trips** (grids + forms).
+- **Phase 6 — Warehouse, then Plan + Dashboard polish.**
+- **Phase 7 — Teardown.** Delete leftover legacy CSS; retire `variables.css` into `theme.ts`; only the slim bespoke-widget CSS remains.
+
+At no point is the app frozen or un-shippable.
+
+---
+
+## 9. Bespoke components & animation
+
+**Bespoke components stay custom, re-themed (their logic is the value):**
+
+- **Plan/gantt grid** (`plan.css`) — keep the grid; repaint from tokens; wrap its controls in the kit.
+- **Leaflet maps** — keep; align container/control styling to the theme.
+- **Quill rich-text** (`react-quill-new`) — keep; wrap as `<RichTextEditor>`; theme the toolbar/editor. **Server-side DOMPurify + `cleanQuillHtml` sanitization on the PDF and render paths is unaffected and must remain.**
+- **@dnd-kit** drag-drop — keep (behavior, not styling).
+
+**Animation (framer-motion).** framer-motion is used in ~40 files, not just modals. Decision: **keep framer-motion** for the animations MUI does not cover — the **AdminLayout logout transition** (scale + blur + fade), **dashboard card entrances**, **Login** transitions, and plan interactions. MUI's own transitions replace framer-motion **only** inside the components that become MUI (`Dialog` for modals, `Snackbar` for toasts). When migrating `AdminLayout`→`<AppShell>` and the dashboard, **consciously re-create or drop** their framer-motion animations (don't lose them silently). `useReducedMotion` continues to gate bespoke animations; MUI honors `prefers-reduced-motion` via its theme transitions.
+
+---
+
+## 10. Testing & verification
+
+This is a UI restyle, so behavior must stay identical (except the deliberate modal a11y gain, §5).
+
+- **Backend/API tests** (`auth`, `numbering`) unaffected; run each phase to confirm the server is untouched — they stay green.
+- **Per-page manual verification checklist** (primary gate): every CRUD action, filter, sort, pagination, and modal works as before; **modal focus order / ESC / backdrop-close** behave; **dark and light** both render; **mobile + desktop** (responsive parity, §11); **zero new console errors**; `tsc --noEmit` and `vite build` pass.
+- **`/ui-kit` dev route:** renders every foundation component in both themes — instant visual QA when tuning the theme; living reference for page migration. Dev-only (stripped from prod).
+- **Playwright smoke + before/after screenshots:** a thin per-page script loads the page, runs the core flow, captures light+dark screenshots to diff against the pre-migration baseline. (Playwright is already available in the environment.)

+
+## 12. Definition of done
+
+- **Per page:** rendered via the `ui/` kit; its CSS file deleted; all interactions verified; **its media queries re-expressed via MUI breakpoints/`sx`**; modal focus/ESC/backdrop verified; dark + light + mobile + desktop pass; `tsc` + `vite build` green; no new console errors; shipped.
+- **Overall:** every page migrated; all per-feature CSS deleted (incl. `responsive.css`); `variables.css` retired into `theme.ts`; only the slim bespoke-widget CSS remains; the dev-only `/ui-kit` route reflects the full theme (and stays stripped from prod).
+
+---
+
+## 13. Out of scope / deferred
+
+- **Puppeteer PDF templates** (`src/routes/admin/invoices-pdf.ts`, `offers-pdf.ts`, `orders-pdf.ts`) use their **own self-contained inline `<style>` + print fonts**, independent of the admin stylesheet — **NOT** part of this migration and not aligned to the MUI theme. (DOMPurify + `cleanQuillHtml` sanitization on those paths is unaffected.) Phase 4's "detail re-themed" refers to the **on-screen** detail page only.
+- Rebuilding the plan/gantt grid from MUI primitives (kept custom-but-themed).
+- Mobile card-view table variant (future enhancement).
+- Any backend, API, or business-logic change.
+- Replacing Leaflet, Quill, or @dnd-kit (kept).
+
+---
+
+## 14. Open items to confirm during planning (Phase 0)
+
+- Confirm **MUI v7** + **MUI X v8** as the pinned versions and re-verify the `cssVariables.colorSchemeSelector` + `colorSchemes` API against the installed version's docs.
+- **Reconcile `@types/react`** with the React 18.3 runtime (or deliberately validate the chosen MUI version against React-18-runtime-with-React-19-types) before committing the kit.
+- Verify each of the three MUI X picker variants under the `date-fns` `cs` adapter: `DatePicker` (date), `DatePicker` month/year views (replacing `showMonthYearPicker`), `TimePicker` (replacing `showTimeSelectOnly`).- Audit the 8 `useModalLock` call sites and decide migrate-now vs keep-until-page-migrates for each.
+- Bundle-size budget/target to check against after Phase 0.
+
+> **Note:** `CLAUDE.md` references a hook named `useListData` that does not exist (the real hook is `usePaginatedQuery`); this spec uses the correct name. Correcting `CLAUDE.md` is advisable but outside this spec's scope.

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

+# Design — Bulk plan creation (Feature B)
+
+**Date:** 2026-06-08
+**Status:** Approved (brainstorming) — ready for implementation plan
+**Builds on:** Feature A (multi-record plan cells, max 3 per cell), shipped in v2.0.5. Spec: `docs/superpowers/specs/2026-06-08-multi-record-plan-cells-design.md`.
+
+---
+
+## Goal
+
+Let a planner assign one project/category to **many employees over a date range
+in a single action**, instead of creating each person's plan record one by one.
+A "Hromadné přiřazení" button on **/plan-work** opens a modal that mirrors the
+existing single-record create form, plus an employee checklist and an "include
+weekends" toggle.
+
+## Decisions (locked in brainstorming)
+
+- **Modal mirrors single-create** (`Datum od` + "Více dní" → `Datum do`, Projekt,
+  Kategorie, Text poznámky) **plus** a multi-select employee checklist and a
+  **"Zahrnout víkendy"** checkbox.
+- **Storage = range entries** (`work_plan_entries`), one per contiguous run of
+  eligible days per employee — the same row shape the single-create form produces.
+- **Weekends:** default off (Mon–Fri only). Only Sat/Sun are excluded — **no
+  separate holiday handling**.
+- **Cap:** governed by Feature A's `MAX_RECORDS_PER_CELL = 3`. A day already at
+  the cap for an employee is **skipped** (never overwritten), which also splits
+  that employee's range around the skipped day.
+- **Past dates blocked** (no `force` exposed in the bulk UI).
+- **Category** picker defaults to **Práce**; **Project** is optional ("bez
+  projektu"); **note** optional, applied to all created entries.
+
+## Non-goals / out of scope
+
+- No DB migration (reuses `work_plan_entries` and Feature A's cap logic).
+- No overwrite/replace of existing records (purely additive under the cap).
+- No holiday/`svátky` exclusion (only weekends).
+- No bulk creation of **overrides** — bulk always creates **entries** (the normal
+  layer); single-day exceptions remain the per-cell day-panel's job.
+
+---
+
+## Storage & weekend behaviour
+
+For each selected employee, the service computes the **eligible days** in
+`[date_from, date_to]` and groups **contiguous** eligible days into range
+entries.
+
+A day `D` is **eligible** for employee `U` when all hold:
+
+1. `D` is within `[date_from, date_to]` (inclusive).
+2. `include_weekends` is true, **or** `D` is a weekday (Mon–Fri).
+3. `U` has fewer than `MAX_RECORDS_PER_CELL` active entries covering `D` (under
+   the cap).
+
+Contiguous runs of eligible days become one range entry each
+(`date_from = run start`, `date_to = run end`). Consequences:
+
+- **Víkendy ON, no cap conflicts:** one continuous range per employee — identical
+  to creating a single multi-day record for everyone.
+- **Víkendy OFF:** one range per work-week (Mon–Fri chunks), because a weekend day
+  breaks the run.
+- **A cap-full day** breaks the run too, so the range splits around it (and that
+  `(employee, day)` is counted as skipped).
+
+In the grid these are ordinary range entries — they show the "součást rozsahu"
+badge and open the range-vs-this-day chooser on click, exactly like
+manually-created ranges.
+
+---
+
+## Backend
+
+### Route — `POST /api/admin/plan/entries/bulk`
+
+- Guard: `requirePermission("attendance.manage")` (same as single entry create).
+- Body (validated by a new Zod schema `BulkPlanEntrySchema` in
+  `src/schemas/plan.schema.ts`):
+  ```
+  {

+    category: string          // default applied client-side; validated server-side
+    note?: string             // default ""
+  }
+  ```
+- On success: one **summary audit** row (`logAudit`, action `create`, entityType
+  `work_plan_entry`, description e.g. `Hromadné přiřazení: <kategorie> <projekt> —
+N zaměstnanců, <from>–<to> (<created_days> dní)`), then `success(reply,
+summary, 201, "Hromadné přiřazení dokončeno")`.
+
+### Service — `bulkCreateEntries(input, actorUserId)` in `src/services/plan.service.ts`
+
+Up-front validation (fail fast, nothing created):
+
+- `user_ids.length >= 1` (else `{ error, status: 400 }`).
+- `date_to >= date_from` (else 400).
+- `assertNotPastDate(date_from, false)` and `assertNotPastDate(date_to, false)`
+  (bulk blocks past dates; 403).
+- `assertActiveCategory(category)` (400 if inactive/unknown).
+
+Then, per employee:
+
+- Load the employee's active entries overlapping `[date_from, date_to]` once;
+  compute per-day coverage counts.
+- Walk the days, mark eligible ones (weekday filter + under-cap), group contiguous
+  runs.
+- For each run, create the range by **reusing `createEntry`**
+  (`{ user_id, date_from: runStart, date_to: runEnd, project_id, category, note }`,
+  `actorUserId`, `force: false`). Reusing `createEntry` keeps cap / past-date /
+  category validation DRY; its cap re-check passes because every day in the run is
+  already under the cap. A `createEntry` that nonetheless returns `{ error }` (rare
+  race) is counted as skipped, not fatal.
+
+Aggregate and return:
+
+```
+{
+  created_entries: number   // range rows created
+  created_days: number      // (employee, day) records created
+  skipped_days: number      // weekday-eligible (employee, day) slots skipped at the cap
+  users: number             // employees processed
+}
+```
+
+`skipped_days` counts only days that passed the weekday filter but were at the
+cap — weekend days (when excluded) are out of scope, not "skipped".
+
+Best-effort across employees/segments (no cross-entry transaction): up-front
+validation already rejects bad input, and the cap-skip is by design. Partial
+results are reported in the summary.
+

+
+## Frontend
+
+### Modal — `src/admin/components/BulkPlanModal.tsx`
+
+Mirrors the single-create `EditForm` fields + bulk-attendance's employee picker
+(`BulkAttendanceModal.tsx` is the pattern to follow):
+
+- `Datum od` (DateField) + "Více dní" CheckboxField → `Datum do` (DateField).
+- **Zaměstnanci** — scrollable `CheckboxField` list (source: the plan users
+  already loaded for the grid, `/plan/users`), with a "Vybrat vše" / "Odznačit
+  vše" toggle and a "Vybráno X z Y" caption; submit disabled when none selected.
+- **Zahrnout víkendy** CheckboxField (default off).
+- **Projekt** Select (optional — "— bez projektu —"), **Kategorie** Select
+  (active categories, default `work`/Práce), **Text poznámky** TextField (optional).
+- A short helper line, e.g. _"Vytvoří záznamy pro vybrané dny u zvolených
+  zaměstnanců. Dny nad limit 3 záznamů se přeskočí."_
+
+### Wiring — `src/admin/pages/PlanWork.tsx`
+
+- A "Hromadné přiřazení" Button in the toolbar (next to "Správa kategorií"),
+  rendered only when `canEdit` (`attendance.manage`).
+- A `bulkCreate` mutation (React Query) → `POST /api/admin/plan/entries/bulk`;
+  on success show an alert summarising the returned counts (e.g. _"Vytvořeno 18
+  záznamů pro 5 zaměstnanců; 4 dny přeskočeny (limit 3 na den)."_), close the
+  modal, and `invalidate: ["plan"]` so the grid refreshes.
+
+---
+
+## Testing (`src/__tests__/plan.test.ts` or a new `bulkPlan.test.ts`)
+
+Backend service tests against the real test DB:
+
+- **Weekday filter:** weekends-off over a Mon–Sun span creates only Mon–Fri days
+  (and as the expected number of per-work-week ranges); weekends-on creates one
+  continuous range.
+- **Segmentation:** a cap-full day in the middle splits the range into two; the
+  skipped day is counted in `skipped_days`.
+- **Cap skip:** an employee already at 3 entries on some days gets those days
+  skipped; the summary reflects `created_days` vs `skipped_days`.
+- **Multi-employee aggregation:** `users`, `created_entries`, `created_days` sum
+  correctly across the selected employees.
+- **Validation:** empty `user_ids` → 400; past `date_from` → 403; inactive
+  category → 400; `date_to < date_from` → 400.
+
+Gates: `npx tsc -b --noEmit`, `npm run build`, `npx vitest run`.
+
+## Rollout
+
+Ships as **v2.0.6** via the standard process (commit → tag → Gitea → tarball →
+prod deploy → health check). No migration step. The grid refreshes via
+`["plan"]` invalidation.

+# Design — Multi-record plan cells (max 3 per cell)
+
+**Date:** 2026-06-08
+**Status:** Approved (brainstorming) — ready for implementation plan
+**Feature A of 2.** Feature B (bulk plan creation) is a separate later cycle — see "Deferred: Feature B" at the end.
+
+---
+
+## Goal
+
+Today a plan cell (one person, one day) resolves to **exactly one** record: an
+override hides the planned range, and overlapping range entries collapse to
+"newest wins". The work plan should instead let a cell hold **up to 3 records**,
+so a person can have several assignments on the same day (additive) _and_ still
+get one-day exceptions to a planned range.
+
+This is the enabling model change. The eventual "bulk assign a project to many
+employees over a date range" form (Feature B) will create records under this
+model and respect the 3-per-cell cap.
+
+## Use cases (both required)
+
+1. **Additive** — several projects/tasks the same day (e.g. morning project A,
+   afternoon project B). Both records show in the cell.
+2. **Day exception** — assigned to a multi-day range, but one day differs;
+   replace just that day without splitting the range.
+
+## Non-goals / out of scope
+
+- No bulk-create UI (Feature B).
+- No database migration — the tables already allow multiple rows per
+  (user, day) (the old `work_plan_overrides` uniqueness constraint was dropped in
+  migration `20260605122718_drop_wpo_unique_constraint`).
+- The max is a fixed constant (3), not user-configurable.
+
+---
+
+## Model — "layered" (approved)
+
+Keep the two existing tables and their meaning; stop collapsing them to one
+record.
+
+- **`work_plan_entries` (ranges) = the normal-plan layer.** Multiple active
+  ranges may cover the same day → the **additive** case.
+- **`work_plan_overrides` (single-day) = the exception layer.** When a day has
+  ≥1 active override, the overrides **replace** the range entries for that day
+  (today's "override beats entry" rule, kept) → the **day-exception** case.
+
+### Resolution rule
+
+For a given `(user, day)`:
+
+1. Active overrides for that exact day (`is_deleted = false`). If any →
+   the cell is the overrides, **newest-first, capped at 3**.
+2. Otherwise → active entries covering that day
+   (`date_from ≤ day ≤ date_to`, `is_deleted = false`), **newest-first, capped at 3**.
+3. Otherwise → empty.
+
+The cell is therefore an array of 0–3 `ResolvedCell` items, all from a single
+layer (overrides **or** entries, never mixed). This preserves the "exception
+replaces the day" semantic while allowing additive stacking within each layer.
+
+**Known limitation (accepted):** a range entry and an exception override cannot
+show together on the same day — an override is all-or-nothing for that day. This
+matches what "exception" means.
+
+### Cap (max 3 per cell)
+
+`MAX_RECORDS_PER_CELL = 3` (single constant in `plan.service.ts`).
+
+Enforced on create, per layer, per day:
+
+- **`createOverride`** — reject if the `(user, day)` already has 3 active
+  overrides.
+- **`createEntry`** — reject if **any** day in the new `[date_from, date_to]`
+  range is already covered by 3 active entries for that user. The error names the
+  first offending date (Czech message). Cap counts entries regardless of whether
+  they are currently hidden by an override (simpler and predictable).
+
+`createOverride` **changes from replace-semantics to additive-with-cap**: it no
+longer soft-deletes the existing override for that day. The transaction +
+row-lock that protected the old "at most one active override" invariant is
+repurposed to enforce "at most 3" under concurrency. The `replacedData` /
+`replacedDescription` plumbing (and the route branch that logged the replaced
+row's soft-delete) is removed.
+
+---
+
+## Backend changes
+
+### `src/services/plan.service.ts`
+
+- `ResolvedCell` interface unchanged (still one record).
+- `resolveCell(userId, dateStr)` → returns `ResolvedCell[]` (0–3) using the
+  resolution rule above. Replaces the current single-result + "newest wins"
+  `console.warn`.
+- `resolveGrid(userIds, from, to)` → `cells[userId][dateStr]` becomes
+  `ResolvedCell[]` (empty array, not `null`, for no records). Same two-query
+  load; per (user, day) build the capped array from the right layer.
+- `createEntry` → add the per-day entry-cap check before insert.
+- `createOverride` → drop the soft-delete-replace; add the override-cap check;
+  keep the transaction/lock for race safety; drop `replacedData`.
+- Add `export const MAX_RECORDS_PER_CELL = 3;`.
+
+### `src/routes/admin/plan.ts`
+
+- `POST /plan/overrides` — remove the `result.replacedData` audit branch (no
+  longer produced). Everything else unchanged (cap errors surface via the normal
+  `{ error, status }` path).
+
+### `src/routes/admin/dashboard.ts`
+
+- `today_plan` is built from `resolveCell` → now an **array**. Map each record
+  with its category label + colour (the existing enrichment, applied per item).
+  `result.today_plan` becomes `TodayPlan[]` (possibly empty).
+
+---
+
+## Frontend changes
+
+### Types — `src/admin/lib/queries/plan.ts`
+
+- `GridData.cells: Record<number, Record<string, ResolvedCell[]>>` (was
+  `ResolvedCell | null`).
+
+### Grid — `src/admin/components/PlanGrid.tsx` + `PlanRangeChips.tsx`
+
+- A cell renders **up to 3 stacked records**, each a compact row: category
+  colour bar + category label + project (mono). When the cell has **exactly one**
+  record, also show its note (2-line clamp), as today. With 2–3 records, notes
+  are omitted for density.
+- `--cat-color` is set per record row (not per cell).
+- `onCellClick(userId, date, cells)` passes the **array**. Empty cell → still a
+  one-click create. Occupied cell → opens the day panel (below).
+- Past-day / read-only / weekend / today styling unchanged.
+
+```
+┌─ Jan N. · Čt 12 ───────┐
+│▌ PRÁCE · 26710001      │
+│▌ DOVOLENÁ              │
+│▌ ŠKOLENÍ · 26710044    │
+└────────────────────────┘   ▌ = category colour bar
+```
+
+### Cell editor — `src/admin/components/PlanCellModal.tsx`
+
+New top-level **day-panel** mode shown when a cell has ≥1 record:
+
+- Lists the day's records (each: colour bar, category, project, optional note)
+  with **edit (✎)** and **delete (🗑)** per record.
+- **"+ Přidat záznam"** button, disabled at 3 with a hint
+  ("Maximum 3 záznamy na den"). Add targets the **showing layer**: an entry in
+  normal mode, an override in exception mode — so the panel reads simply as
+  "records for this day" and the entry/override distinction stays invisible.
+- Editing a record reuses the existing `EditForm`. Editing a record that belongs
+  to a **multi-day range** still routes through the existing `day-in-range`
+  chooser ("edit whole range" vs "carve out this day" = create override).
+- Empty cell skips the panel and opens the create form directly (current
+  behaviour).
+
+`PlanWork.tsx` wires the new panel: cell-click opens it with the array; the
+panel's per-record actions reuse the existing entry/override create/update/delete
+mutations and `invalidate: ["plan"]`.
+
+### Dashboard — `DashTodayPlan.tsx` + `Dashboard.tsx`
+
+- `today_plan` prop becomes `TodayPlan[]`. Render up to 3 records stacked
+  (reuse the existing single-record card layout per item). Empty array → the
+  existing "Pro dnešek nemáte naplánováno." state.
+
+---
+
+## Testing (`src/__tests__/plan.test.ts`)
+
+Update existing assertions for the array shape, and add:
+
+- `resolveCell` returns `[]` for an empty day; one item for a single entry; the
+  override layer (entries hidden) when an override exists.
+- **Additive:** two entries covering the same day → both returned (newest first).
+- **Cap display:** 4 overlapping entries on a day → only 3 returned.
+- **Cap enforcement:** `createEntry` rejects when a day in range already has 3
+  entries (error names the date); `createOverride` rejects at 3 overrides.
+- **Additive overrides:** `createOverride` no longer soft-deletes the prior
+  override; two overrides on a day coexist.
+- `resolveGrid` cell arrays match `resolveCell` for the same (user, day).
+
+Gates: `npx tsc -b --noEmit`, `npm run build`, `npx vitest run`.
+
+## Rollout
+
+Ships as its own release (**v2.0.5**) via the standard process (commit → tag →
+Gitea → tarball → prod deploy → health check). No migration step.
+
+---
+
+## Deferred: Feature B (bulk plan creation) — decisions captured
+
+A later, separate spec + cycle. Locked decisions from this brainstorming:
+
+- **Form:** select one project, a date range (from–to), and multiple employees;
+  create the assignment for all of them at once.
+- **Category:** a category picker in the bulk form, **default Práce**.
+- **Weekends:** an **"include weekends" checkbox** (off = Mon–Fri only, which
+  requires splitting each person into per-work-week entries; on = one continuous
+  range).
+- **Conflict handling:** governed by this feature's **max-3-per-cell** rule — for
+  each employee/day, create the record only if the cell is under the cap;
+  otherwise **skip** that day (no error).

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

+
+  @@index([conversation_id, id], map: "idx_ai_chat_conv")
+}
+```
+
+### Migration (hand-written SQL; one tracked migration)
+
+1. `CREATE TABLE ai_conversations (...)`.
+2. `ALTER TABLE ai_chat_messages ADD COLUMN conversation_id INT NULL AFTER user_id`.
+3. Backfill one conversation per user who has messages:
+   `INSERT INTO ai_conversations (user_id, title, created_at, updated_at)
+ SELECT user_id, 'Konverzace', NOW(), NOW() FROM ai_chat_messages GROUP BY user_id;`
+4. Point messages at it:
+   `UPDATE ai_chat_messages m JOIN ai_conversations c ON c.user_id = m.user_id
+ SET m.conversation_id = c.id;`
+5. Drop the old index, enforce NOT NULL, add the FK + new index:
+   `ALTER TABLE ai_chat_messages DROP INDEX idx_ai_chat_user,
+ MODIFY conversation_id INT NOT NULL,
+ ADD CONSTRAINT fk_ai_chat_conv FOREIGN KEY (conversation_id)
+   REFERENCES ai_conversations(id) ON DELETE CASCADE,
+ ADD INDEX idx_ai_chat_conv (conversation_id, id);`
+
+The backfill is a no-op when `ai_chat_messages` is empty (prod today), and
+preserves the dev thread.
+
+## Service layer (`ai.service.ts`)
+
+Replace the single-thread helpers (`getChatHistory` / `appendChatMessages` /
+`clearChatHistory`) with conversation-scoped ones. Every function takes
+`userId` and verifies the conversation belongs to the user.
+
+- `listConversations(userId)` → `{id, title, updated_at}[]`, ordered by `id` asc
+  (stable tab order).
+- `createConversation(userId, title?)` → the new conversation (default title
+  "Nová konverzace").
+- `getConversation(userId, id)` → conversation or null (ownership check helper).
+- `getConversationMessages(userId, id)` → `StoredChatMessage[]` oldest→newest,
+  or `{ error, status }` if not owned/found.
+- `appendConversationMessages(userId, id, msgs)` → append; **bump `updated_at`**;
+  **auto-title**: if the conversation's title is still the default and this batch
+  has a user message, set `title` = first ~60 chars of that user message.
+- `renameConversation(userId, id, title)` / `deleteConversation(userId, id)` —
+  ownership-checked; delete cascades messages.
+
+Auto-title keeps titling server-side and robust (no client title logic).
+
+## Routes (`routes/admin/ai.ts`, all `requirePermission("ai.use")`)
+
+| Method | Path                          | Body / result                              |
+| ------ | ----------------------------- | ------------------------------------------ |
+| GET    | `/conversations`              | → `{ conversations: [...] }`               |
+| POST   | `/conversations`              | `{ title? }` → `{ conversation }`          |
+| GET    | `/conversations/:id/messages` | → `{ messages: [...] }` (404 if not owned) |
+| POST   | `/conversations/:id/messages` | `{ messages:[{role,content}] }` (1..20)    |
+| PATCH  | `/conversations/:id`          | `{ title }` (1..255)                       |
+| DELETE | `/conversations/:id`          | → `{ ok: true }`                           |
+
+`:id` parsed via `parseId`; bodies via `parseBody`; ownership 404 from the
+service surfaced with `error(reply, ...)`. The old `/history` routes are removed.
+`/chat`, `/extract-invoices`, `/usage`, `/budget` are unchanged.
+
+## Frontend
+
+### Queries (`lib/queries/ai.ts`)
+
+- `aiConversationsOptions()` → `["ai","conversations"]`, `GET /conversations`.
+- `aiConversationMessagesOptions(id)` → `["ai","conversation",id,"messages"]`,
+  `GET /conversations/:id/messages`, `gcTime: 0` (each mount re-reads the DB,
+  same rationale as today: no stale-cache resurrection).
+- Types: `Conversation { id, title, updated_at }`, reuse `StoredChatMessage`.
+
+### Components (`src/admin/components/odin/`)
+
+- **`OdinChat.tsx`** — orchestrator. Owns: active conversation id, input, busy,
+  staged attachments, review list. Loads the conversation list; ensures one
+  exists (creates a default if the user has none); loads the active thread;
+  routes send/extract/save through the active conversation. Full-height flex
+  layout: header → tabs → thread (flex-grow, scroll) → review → composer.
+- **`OdinTabs.tsx`** — horizontally-scrollable tabs (one per conversation) +
+  a "+" new-chat button + a ⋮ menu on the active tab (Přejmenovat / Smazat).
+  Rename uses a small Modal with a text field; delete uses ConfirmDialog.
+- **`OdinThread.tsx`** — message list with an Odin avatar on assistant turns,
+  user turns right-aligned; the "Pracuji…" indicator; empty-state greeting.
+  (Message text colour set on the `Typography` — GlobalStyles pins `p` to
+  text.secondary.)
+- **`InvoiceReviewCard.tsx`** — the editable extract card (supplier, number,
+  Částka s DPH, měna, sazba, dates, popis) + Uložit / Zahodit.
+- **`OdinComposer.tsx`** — staged-attachment chips + attach button + message
+  field (Enter to send) + send button; disabled until the active thread loads.
+
+`DashAssistant.tsx` is deleted; `pages/Odin.tsx` renders `OdinChat`.
+
+### Data flow
+
+1. Mount → load `aiConversationsOptions`. If empty, `POST /conversations` to
+   create a default and select it; else select the first (or last-active).
+2. Selecting a tab sets the active id → `aiConversationMessagesOptions(id)`
+   loads that thread into the displayed turns (seed-once per id; submit marks
+   the thread live so a late load can't clobber — same guard as today).
+3. **Send (chat):** optimistic user turn → `POST /chat` → append assistant
+   reply → `POST /conversations/:id/messages` persists both → bump usage. On
+   error: roll back, keep input.
+4. **Send (attachments):** `POST /extract-invoices` → review cards →
+   client-side summary turn → persist the user+summary turns. Save a card →
+   `POST /received-invoices` (gross/VAT-inclusive, unchanged).
+5. **New / rename / delete** → mutations that invalidate `["ai","conversations"]`
+   (and reset the active id appropriately on delete).
+
+### Reuse
+
+All proven logic carries over verbatim: staged-attach (no auto-send), the three
+bug fixes (no clear-on-error, rollback dangling turn, stable ids — `nextUid`,
+NOT `crypto.randomUUID`), the model-context trimming (last 20, leading-user),
+budget indicator, gross/VAT save. The only structural change is "one thread" →
+"active conversation thread", plus the tab/CRUD shell.
+
+## Error handling
+
+- Ownership: service returns `{ error: "Konverzace nenalezena", status: 404 }`
+  for a conversation the user doesn't own; routes surface it. No cross-user read
+  or write is possible (every query filters by `user_id`).
+- Persistence is best-effort and logged (never swallowed), as today.
+- Auto-create-default and create/rename/delete failures surface a Czech toast.
+
+## Testing
+
+Backend (Vitest, real DB):
+
+- Conversation CRUD: create → list → rename → delete (cascade removes messages).

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