+## Overview
+
+VS Code Dev Container configuration for a pre-configured development environment. Includes Java 21, Maven, and Node.js 24 — everything needed to work on both backend and frontend.
+
+## Configuration
+
+File: `.devcontainer/devcontainer.json`
+
+### Included Features
+
+| Feature | Version | Purpose |
+|---|---|---|
+| Java | 21 | Spring Boot backend |
+| Maven | bundled with Java feature | Build tool |
+| Node.js | 24 | SvelteKit frontend |
+
+### VS Code Extensions (Auto-installed)
+
+| Extension | Purpose |
+|---|---|
+| `vscjava.vscode-java-pack` | Java language support, debugging, testing |
+| `vmware.vscode-spring-boot` | Spring Boot tooling |
+| `gabrielbb.vscode-lombok` | Lombok annotation support |
+| `humao.rest-client` | HTTP request files (for `backend/api_tests/`) |
+
+### Ports
+
+- `8080` forwarded to host — access backend at `http://localhost:8080`
+
+### User
+
+Runs as `vscode` user (not root) for security.
+
+## How to Use
+
+### Prerequisites
+
+- VS Code with the **Dev Containers** extension installed
+- Docker running locally
+
+### Open in Dev Container
+
+1. Open the project in VS Code
+2. Press `F1` → type "Dev Containers: Reopen in Container"
+3. VS Code will:
+   - Build the container using the root `docker-compose.yml`
+   - Install Java 21, Maven, and Node 24
+   - Install the listed extensions
+   - Mount the workspace folder
+
+### Working Inside the Container
+
+Once inside the container, you have access to both stacks:
+
+```bash
+# Backend
+cd backend
+./mvnw spring-boot:run
+
+# Frontend (in a new terminal)
+cd frontend
+npm install
+npm run dev
+```
+
+The container reuses the `docker-compose.yml` services, so PostgreSQL and MinIO are available automatically.
+
+### Forwarding Frontend Port
+
+The devcontainer config only forwards port 8080 by default. To access the frontend dev server (port 5173 or 3000), either:
+
+1. Add `5173` to `forwardPorts` in `devcontainer.json`, or
+2. Use the VS Code "Ports" panel to forward it dynamically
+
+## Limitations
+
+- The devcontainer attaches to the `backend` service from `docker-compose.yml`, so it inherits those environment variables
+- OCR service and other containers should be started separately via `docker-compose up -d`
+- GPU passthrough for OCR training is not configured
+
+## Customization
+
+To add more tools or extensions, edit `.devcontainer/devcontainer.json`:
+
+```json
+{
+  "features": {
+    "ghcr.io/devcontainers/features/python:1": {
+      "version": "3.11"
+    }
+  },
+  "forwardPorts": [8080, 5173, 3000]
+}

+- `DocumentUpdateDTO` — used for both create and update (all fields optional)
+- `CreateUserRequest` — user creation
+- `GroupDTO` — group create/update
 
 ### Error Handling
 
-→ See [CONTRIBUTING.md §Error handling](./CONTRIBUTING.md#error-handling)
+Use `DomainException` for all domain errors. Never throw raw exceptions from service methods.
 
-**LLM reminder:** use `DomainException.notFound/forbidden/conflict/internal()` from service methods — never throw raw exceptions. When adding a new `ErrorCode`: (1) add to `ErrorCode.java`, (2) add to `ErrorCode` type in `frontend/src/lib/shared/errors.ts`, (3) add a `case` in `getErrorMessage()`, (4) add i18n keys in `messages/{de,en,es}.json`. Valid error codes include: `TOO_MANY_LOGIN_ATTEMPTS` (returned by `LoginRateLimiter` as HTTP 429 when a brute-force threshold is exceeded); `SMART_SEARCH_UNAVAILABLE` (HTTP 503 — Ollama inference service offline or timed out); `SMART_SEARCH_RATE_LIMITED` (HTTP 429 — user exceeded 5 NL search requests per minute).
+```java
+// Static factories match common HTTP status codes:
+DomainException.notFound(ErrorCode.DOCUMENT_NOT_FOUND, "Document not found: " + id)
+DomainException.forbidden("Access denied")
+DomainException.conflict(ErrorCode.IMPORT_ALREADY_RUNNING, "Already running")
+DomainException.internal(ErrorCode.FILE_UPLOAD_FAILED, "Upload failed: " + e.getMessage())
+```
+
+`ErrorCode` is an enum in `exception/ErrorCode.java`. When adding a new error case, add the value there **and** mirror it in the frontend's `src/lib/errors.ts` + add a Paraglide translation key.
+
+For simple validation in controllers (not domain logic), `ResponseStatusException` is acceptable:
+```java
+throw new ResponseStatusException(HttpStatus.BAD_REQUEST, "firstName is required");
+```
 
 ### Security / Permissions
 
-→ See [docs/ARCHITECTURE.md §Permission system](./docs/ARCHITECTURE.md#permission-system)
+Use `@RequirePermission` on controller methods (or the whole controller class):
 
-**LLM reminder:** `@RequirePermission(Permission.WRITE_ALL)` is **required** on every `POST`, `PUT`, `PATCH`, `DELETE` endpoint — not optional. Do not mix with Spring Security's `@PreAuthorize`. Available permissions: `READ_ALL`, `WRITE_ALL`, `ADMIN`, `ADMIN_USER`, `ADMIN_TAG`, `ADMIN_PERMISSION`, `ANNOTATE_ALL`, `BLOG_WRITE`.
+```java
+@RequirePermission(Permission.WRITE_ALL)
+public Document updateDocument(...) { ... }
+```
+
+Available permissions: `READ_ALL`, `WRITE_ALL`, `ADMIN`, `ADMIN_USER`, `ADMIN_TAG`, `ADMIN_PERMISSION`
+
+`PermissionAspect` (AOP) checks the current user's `UserGroup.permissions` at runtime.
 
 ### OpenAPI / API Types
 
-→ See [CONTRIBUTING.md §Walkthrough B — Add a new endpoint](./CONTRIBUTING.md#4-walkthrough-b--add-a-new-endpoint)
+SpringDoc generates the spec at `/v3/api-docs` (only accessible when running with `--spring.profiles.active=dev`).
 
-**LLM reminder:** always run `npm run generate:api` in `frontend/` after any backend model or endpoint change — this is the most common cause of TypeScript type errors.
+When changing any model field or endpoint:
+1. Rebuild the backend JAR with `-DskipTests`
+2. Start it with `--spring.profiles.active=dev`
+3. Run `npm run generate:api` in `frontend/`

 ### API Client Pattern
 
-→ See [CONTRIBUTING.md §Frontend API client](./CONTRIBUTING.md#frontend-api-client)
+All server-side API calls use the typed client from `$lib/api.server.ts`:
 
-**LLM reminder:** check `!result.response.ok` (not `result.error` — breaks when spec has no error responses defined); cast errors as `result.error as unknown as { code?: string }`; use `result.data!` after an ok check.
+```typescript
+const api = createApiClient(fetch);
+const result = await api.GET('/api/persons/{id}', { params: { path: { id } } });
+
+// Always check via response.ok, NOT result.error
+if (!result.response.ok) {
+    const code = (result.error as unknown as { code?: string })?.code;
+    throw error(result.response.status, getErrorMessage(code));
+}
+return { person: result.data! };
+```
+
+Key rules:
+- Use `!result.response.ok` for error checking (not `if (result.error)` — this breaks when the spec has no error responses defined)
+- Cast errors as `result.error as unknown as { code?: string }` to extract the backend error code
+- Use `result.data!` (non-null assertion) after an ok check — TypeScript knows it's present
+
+For multipart/form-data endpoints (file uploads), bypass the typed client and use raw `fetch`:
+```typescript
+const res = await fetch(`${baseUrl}/api/documents`, { method: 'POST', body: formData });
+```
 
 ### Form Actions Pattern
 
 ```typescript
 // +page.server.ts
 export const actions = {
-  default: async ({ request, fetch }) => {
-    const formData = await request.formData();
-    const name = formData.get("name") as string;
-    // ...
-    return fail(400, { error: "message" }); // on error
-    throw redirect(303, "/target"); // on success
-  },
+    default: async ({ request, fetch }) => {
+        const formData = await request.formData();
+        const name = formData.get('name') as string;  // cast needed — FormData returns FormDataEntryValue
+        // ...
+        return fail(400, { error: 'message' });  // on error
+        throw redirect(303, '/target');           // on success
+    }
 };

 ### Date Handling
 
-→ See [CONTRIBUTING.md §Date handling](./CONTRIBUTING.md#date-handling)
-
-**LLM reminder:** always append `T12:00:00` when constructing `new Date()` from an ISO date string — prevents UTC timezone off-by-one errors.
+- **Forms**: German format `dd.mm.yyyy` with auto-dot insertion via `handleDateInput()`. A hidden `<input type="hidden" name="documentDate" value={dateIso}>` sends ISO format to the backend.
+- **Display**: Always use `Intl.DateTimeFormat` with `T12:00:00` suffix to prevent UTC timezone off-by-one:
+  ```typescript
+  new Intl.DateTimeFormat('de-DE', { day: 'numeric', month: 'long', year: 'numeric' })
+      .format(new Date(doc.documentDate + 'T12:00:00'))
+  ```

+| `PersonMultiSelect` | `selectedPersons` (bind) | Chip-based multi-person selector |
+| `TagInput` | `tags` (bind), `allowCreation?`, `on:change` | Tag chip input with typeahead |
 
 ### Styling Conventions (Tailwind CSS 4)
 
-Brand color tokens (defined in `layout.css`):
+Brand color utilities (defined in `layout.css`):
 
-| Token / Utility  | CSS variable     | Usage                                                   |
-| ---------------- | ---------------- | ------------------------------------------------------- |
-| `brand-navy`     | `--palette-navy` | Tailwind utility — buttons, headers, primary text       |
-| `brand-mint`     | `--palette-mint` | Tailwind utility — accents, hover underlines, icons     |
-| `--palette-sand` | `--palette-sand` | Palette constant only — use `bg-canvas` or `bg-surface` |
+| Class | Value | Usage |
+|---|---|---|
+| `brand-navy` | `#002850` | Primary text, buttons, headers |
+| `brand-mint` | `#A6DAD8` | Accents, hover underlines, icons |
+| `brand-sand` | `#E4E2D7` | Page background, card borders |
 
 Typography:
-
-- `font-serif` (Tinos) — body text, document titles, names
+- `font-serif` (Merriweather) — body text, document titles, names
 - `font-sans` (Montserrat) — labels, metadata, UI chrome
 
 Card pattern for content sections:
-
 ```svelte
-<div class="rounded-sm border border-line bg-surface shadow-sm p-6">
-    <h2 class="text-xs font-bold uppercase tracking-widest text-ink-3 mb-5">Section Title</h2>
+<div class="bg-white shadow-sm border border-brand-sand rounded-sm p-6">
+    <h2 class="text-xs font-bold uppercase tracking-widest text-gray-400 mb-5">Section Title</h2>
     <!-- content -->
 </div>
 ```
 
-Back button pattern — use the shared `<BackButton>` component from `$lib/shared/primitives/BackButton.svelte`. Do not use a static `<a href>` for back navigation.
+Save bar pattern — use **sticky full-bleed** for long forms (edit document), **card-style with `mt-4`** for short forms (new person):
+```svelte
+<!-- Long forms: sticky, full-bleed -->
+<div class="sticky bottom-0 z-10 -mx-4 px-6 py-4 bg-white border-t border-brand-sand shadow-[0_-2px_8px_rgba(0,0,0,0.06)] flex items-center justify-between">
+
+<!-- Short forms: card, top margin -->
+<div class="mt-4 flex items-center justify-between rounded-sm border border-brand-sand bg-white px-6 py-4 shadow-sm">
+```
+
+Back button pattern — use the shared `<BackButton>` component from `$lib/components/BackButton.svelte`:
+```svelte
+<script lang="ts">
+    import BackButton from '$lib/components/BackButton.svelte';
+</script>
+
+<BackButton />
+```
+The component calls `history.back()` so the user returns to wherever they came from. Label is always "Zurück" (no contextual suffix — destination is unknown). Touch target ≥ 44px and focus ring are built in. Do not use a static `<a href>` for back navigation.
+
+Subtle action link (e.g. "new document/person"):
+```svelte
+<a href="/documents/new" class="inline-flex items-center gap-1 text-sm font-medium text-brand-navy/60 hover:text-brand-navy transition-colors">
+    <svg class="w-4 h-4" ...><!-- plus icon --></svg>
+    Neues Dokument
+</a>
+```
 
 ### Error Handling (Frontend)
 
-→ See [CONTRIBUTING.md §Error handling](./CONTRIBUTING.md#error-handling)
-
-**LLM reminder:** when adding a new `ErrorCode`: (1) add to `ErrorCode.java`, (2) add to `ErrorCode` type in `frontend/src/lib/shared/errors.ts`, (3) add a `case` in `getErrorMessage()`, (4) add i18n keys in `messages/{de,en,es}.json`. Valid error codes include: `TOO_MANY_LOGIN_ATTEMPTS` (returned by `LoginRateLimiter` as HTTP 429 when a brute-force threshold is exceeded); `SMART_SEARCH_UNAVAILABLE` (HTTP 503 — Ollama inference service offline or timed out); `SMART_SEARCH_RATE_LIMITED` (HTTP 429 — user exceeded 5 NL search requests per minute).
+`src/lib/errors.ts` mirrors the backend `ErrorCode` enum and maps codes to Paraglide translation keys. When adding a new `ErrorCode` on the backend:
+1. Add it to `ErrorCode.java`
+2. Add it to the `ErrorCode` type in `errors.ts`
+3. Add a `case` in `getErrorMessage()`
+4. Add the translation key in `messages/de.json`, `en.json`, `es.json`

 ## Infrastructure
 
-→ See [docs/DEPLOYMENT.md](./docs/DEPLOYMENT.md)

-## 1. Environment setup
-
-**Prerequisites:** Java 21 (SDKMAN), Node 24 (nvm), Docker
-
-**Activate SDKMAN and nvm before running `java`, `mvn`, `node`, or `npm`:**
-
-```bash
-source "$HOME/.sdkman/bin/sdkman-init.sh"
-export NVM_DIR="$HOME/.nvm" && [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
-```
-
----
-
-## 2. Daily development workflow
-
-**Startup order — services must start in this sequence:**
-
-```bash
-# 1. Start PostgreSQL and MinIO
-docker compose up -d db minio
-
-# 2. Start the backend (separate terminal)
-cd backend && ./mvnw spring-boot:run
-
-# 3. Start the frontend (separate terminal)
-cd frontend && npm install && npm run dev
-```
-
-> `npm install` also wires up the Husky pre-commit hook via the `prepare` script.
-> Run it before your first commit, or the hook will fail to execute.
-
-> **Do not use `docker-compose.ci.yml` locally** — it disables the bind mounts that the dev workflow depends on.
-
-**Regenerate TypeScript types after any backend API change:**
-
-```bash
-# Backend must be running with dev profile
-cd frontend && npm run generate:api
-```
-
-> ⚠️ Forgetting this step is the most common cause of "where did my TypeScript type go?" — always regenerate after changing models or endpoints.
-
-**Test commands:**
-
-```bash
-cd backend && ./mvnw test                 # backend unit + slice tests
-cd frontend && npm run test               # Vitest unit tests
-cd frontend && npm run check              # svelte-check (type errors)
-cd frontend && npx playwright test        # Playwright e2e tests

-## 3. Walkthrough A — Add a new domain
-
-**Example:** adding a `citation` domain (formal references to documents).
-
-Both the backend and frontend are organised **domain-first**. A new domain means adding a package on both sides under the same name.
-
-### Backend
-
-1. Create `backend/src/main/java/org/raddatz/familienarchiv/citation/`
-
-2. Add entity, repository, service, controller, and DTOs flat in the package:
-   - **Entity** `Citation.java` — annotate with `@Entity @Data @Builder @NoArgsConstructor @AllArgsConstructor`; use `@GeneratedValue(strategy = GenerationType.UUID)` for the `id` field; add `@Schema(requiredMode = REQUIRED)` on every field the backend always populates
-   - **Repository** `CitationRepository.java` — extends `JpaRepository<Citation, UUID>`
-   - **Service** `CitationService.java` — `@Service @RequiredArgsConstructor`; write methods `@Transactional`, read methods unannotated; cross-domain data goes through the other domain's service, never its repository
-   - **Controller** `CitationController.java` — `@RestController @RequestMapping("/api/citations")`
-
-3. Add `@RequirePermission(Permission.WRITE_ALL)` on every `POST`, `PUT`, `PATCH`, and `DELETE` endpoint — **this is not optional**. Read-only `GET` endpoints stay unannotated.
-
-4. Add a Flyway migration: `backend/src/main/resources/db/migration/V{n}__{description}.sql` (use the next sequential number after the highest existing one).
-
-5. **Write failing tests before any implementation** (Red step):
-   - Service unit test for business logic (`@ExtendWith(MockitoExtension.class)`)
-   - `@WebMvcTest` slice test for each HTTP endpoint
-
-6. Rebuild with `--spring.profiles.active=dev` and run `npm run generate:api` in `frontend/`.
-
-### Frontend
-
-7. Create `frontend/src/lib/citation/` — domain-specific Svelte components and TypeScript utilities go here.
-
-8. Add routes under `frontend/src/routes/citations/` as needed.
-
-9. Add a per-domain `README.md` in both the backend package folder and `frontend/src/lib/citation/` (per DOC-6).
-
-### Documentation
-
-10. Update `docs/ARCHITECTURE.md` Section 2 to include the new domain.
-11. Update `docs/GLOSSARY.md` if new terms are introduced.
-12. Update the ESLint boundary allow-list in `frontend/eslint.config.js` if the domain needs to import from another domain.
-
----
-
-## 4. Walkthrough B — Add a new endpoint
-
-**Example:** `POST /api/persons/{id}/aliases` — attach a name alias to an existing person.
-
-### Red (write failing tests first)
-
-1. Write a failing `@WebMvcTest` controller slice test:
-   ```java
-   @Test
-   void addAlias_returns201_whenAliasCreated() { ... }
-   ```
-
-2. Write a failing service unit test:
-   ```java
-   @Test
-   void addAlias_throwsNotFound_whenPersonDoesNotExist() { ... }
-   ```
-
-### Green (implement)
-
-3. Add the service method in `PersonService.java`:
-   ```java
-   @Transactional
-   public PersonNameAlias addAlias(UUID personId, PersonNameAliasDTO dto) { ... }
-   ```
-
-4. Add the controller method in `PersonController.java`:
-   ```java
-   @PostMapping("/{id}/aliases")
-   @RequirePermission(Permission.WRITE_ALL)
-   public ResponseEntity<PersonNameAlias> addAlias(@PathVariable UUID id,
-                                                   @RequestBody PersonNameAliasDTO dto) { ... }
-   ```
-   `@RequirePermission(Permission.WRITE_ALL)` on every state-mutating endpoint — **not optional**.
-
-5. Validate user-supplied inputs at the controller boundary:
-   ```java
-   if (dto.name() == null || dto.name().isBlank())
-       throw new ResponseStatusException(HttpStatus.BAD_REQUEST, "name is required");
-   ```
-   Validate at system boundaries; trust internal service code.
-
-6. Use `DomainException` for domain errors:
-   ```java
-   DomainException.notFound(ErrorCode.PERSON_NOT_FOUND, "Person not found: " + id)
-   ```
-   If you need a new error code, add it to `ErrorCode.java`, mirror it in
-   `frontend/src/lib/shared/errors.ts`, and add translation keys in `messages/{de,en,es}.json`.
-
-7. Mark every field the backend always populates with `@Schema(requiredMode = REQUIRED)` — this drives TypeScript type generation.
-
-### Types and tests
-
-8. Rebuild with `--spring.profiles.active=dev`, then `npm run generate:api` in `frontend/`.
-
-   > ⚠️ **Always regenerate types after any API change.** This is the #1 cause of "where did my TypeScript type go?"
-
-9. Run the full test suite — all green before committing.
-
----
-
-## 5. Walkthrough C — Add a new frontend page
-
-**Example:** `/persons/[id]/timeline` — a chronological event timeline for one person.
-
-### Red (write failing test first)
-
-1. Write a failing Playwright E2E test for the user flow:
-   ```typescript
-   test('timeline shows events in chronological order', async ({ page }) => {
-       await page.goto('/persons/1/timeline');
-       // assertions...
-   });
-   ```
-
-### Green (implement)
-
-2. Create `frontend/src/routes/persons/[id]/timeline/+page.svelte`
-
-3. Add `frontend/src/routes/persons/[id]/timeline/+page.server.ts` for the SSR load:
-   ```typescript
-   import { createApiClient } from '$lib/shared/api.server';
-   export const load: PageServerLoad = async ({ params, fetch }) => {
-       const api = createApiClient(fetch);
-       const result = await api.GET('/api/persons/{id}', { params: { path: { id: params.id } } });
-       if (!result.response.ok) throw error(result.response.status, '...');
-       return { person: result.data! };
-   };
-   ```
-
-4. Domain-specific components (e.g. `TimelineEntry.svelte`) → `frontend/src/lib/person/`
-
-5. Shared primitives (e.g. a generic date-range display) → `frontend/src/lib/shared/primitives/`
-
-6. UI patterns to follow:
-   - Back navigation: `import BackButton from '$lib/shared/primitives/BackButton.svelte'`
-   - Date display: always append `T12:00:00` — `new Intl.DateTimeFormat('de-DE', …).format(new Date(val + 'T12:00:00'))` — prevents UTC off-by-one errors
-   - Brand colors: `brand-navy`, `brand-mint`, `brand-sand` (defined in `src/routes/layout.css`)
-   - Accessibility: touch targets ≥ 44 px (`min-h-[44px]`); focus rings (`focus-visible:ring-2 focus-visible:ring-brand-navy`); `aria-label` on icon-only buttons; `aria-live="polite"` on dynamic status messages
-
-7. Add Paraglide i18n keys in `messages/de.json`, `messages/en.json`, `messages/es.json`.
-
-8. If adding a new error code: mirror in `frontend/src/lib/shared/errors.ts` and add translation keys.
-
-9. Make all tests green before committing.

-
-## 6. Conventions reference
-
-### Error handling
-
-| Scenario | Pattern |
-|---|---|
-| Domain entity not found | `DomainException.notFound(ErrorCode.X, "…")` |
-| Permission denied | `DomainException.forbidden("…")` |
-| Concurrent edit conflict | `DomainException.conflict(ErrorCode.X, "…")` |
-| Infrastructure failure | `DomainException.internal(ErrorCode.X, "…")` |
-| Simple controller validation | `throw new ResponseStatusException(HttpStatus.BAD_REQUEST, "…")` |
-
-New error code: `ErrorCode.java` → `frontend/src/lib/shared/errors.ts` → `messages/{de,en,es}.json`.
-
-### DTOs
-
-- Input DTOs live flat in the domain package (e.g. `PersonUpdateDTO.java`)
-- Responses are the entity itself — no separate response DTOs
-- `@Schema(requiredMode = REQUIRED)` on every field the backend always populates
-
-### Frontend API client
-
-```typescript
-const api = createApiClient(fetch); // from $lib/shared/api.server
-const result = await api.GET('/api/persons/{id}', { params: { path: { id } } });
-if (!result.response.ok) {
-    const code = (result.error as unknown as { code?: string })?.code;
-    throw error(result.response.status, getErrorMessage(code));
-}
-return { person: result.data! }; // non-null assertion is safe after the ok check
-```
-
-For multipart/form-data (file uploads): bypass the typed client and use `event.fetch` directly — never global `fetch`. The typed client cannot handle multipart bodies, but `event.fetch` is still required so that `handleFetch` injects the session cookie.
-
-### Date handling
-
-| Context | Pattern |
-|---|---|
-| Form display | German `dd.mm.yyyy` with auto-dot insertion via `handleDateInput()` |
-| Wire format | ISO 8601 via a hidden `<input type="hidden" name="documentDate" value={dateIso}>` |
-| Display | `new Intl.DateTimeFormat('de-DE', …).format(new Date(val + 'T12:00:00'))` |
-| Honest precision display | `formatDocumentDate(iso, precision, end?, raw?, locale?)` (`$lib/shared/utils/documentDate.ts`) or the `<DocumentDate>` component — renders a document date at exactly its `meta_date_precision` (MONTH → "Juni 1916", never a fabricated day). It mirrors the Java `DocumentTitleFormatter`; both are pinned to `docs/date-label-fixtures.json` so the title and UI labels can't drift. `meta_date_raw` is untrusted — render it via default escaping, never `{@html}` (a CI guard enforces this). |
-
-### Security checklist (new endpoint)
-
-- `@RequirePermission(Permission.WRITE_ALL)` on every `POST`, `PUT`, `PATCH`, `DELETE` — required, not optional
-- Validate all user-supplied inputs at the controller boundary before passing to the service
-- Parameterised queries only — never interpolate user input into JPQL/SQL strings
-- No raw user input in log messages — use `{}` placeholders: `log.warn("Not found: {}", id)`
-- Validate content-type and size on upload endpoints before reading the stream
-
-### Accessibility baseline (new frontend page)
-
-- Touch targets ≥ 44 px on all interactive elements (`min-h-[44px]`)
-- Focus rings on all focusable elements (`focus-visible:ring-2 focus-visible:ring-brand-navy`)
-- `aria-label` on every icon-only button
-- `aria-live="polite"` on dynamic status messages
-- Color is never the sole status indicator
-
-Full WCAG 2.1 AA reference: [docs/STYLEGUIDE.md](./docs/STYLEGUIDE.md).
-
-### Lint and format
-
-```bash
-# Frontend
-cd frontend && npm run lint     # Prettier + ESLint check
-cd frontend && npm run format   # Auto-fix formatting
-cd frontend && npm run check    # svelte-check (type errors)
-
-# Backend — no standalone lint tool; compilation and test runs catch style issues
-cd backend && ./mvnw test       # compile + test
-cd backend && ./mvnw clean package -DskipTests  # compile-only check
-```

 ## Error Handling
 
-→ See [CONTRIBUTING.md §Error handling](../CONTRIBUTING.md#error-handling)
+Use `DomainException` for all domain errors:
 
-**LLM reminder:** use `DomainException.notFound/forbidden/conflict/internal()` — never throw raw exceptions from service methods. For simple controller validation (not domain logic), `ResponseStatusException` is acceptable: `throw new ResponseStatusException(HttpStatus.BAD_REQUEST, "…")`. When adding a new `ErrorCode`: add to `ErrorCode.java`, mirror in `frontend/src/lib/shared/errors.ts`, add i18n keys in `messages/{de,en,es}.json`.
+```java
+DomainException.notFound(ErrorCode.DOCUMENT_NOT_FOUND, "...")
+DomainException.forbidden("...")
+DomainException.conflict(ErrorCode.IMPORT_ALREADY_RUNNING, "...")
+DomainException.internal(ErrorCode.FILE_UPLOAD_FAILED, "...")
+```
+
+When adding a new `ErrorCode`:
+1. Add to `ErrorCode.java`
+2. Mirror in frontend `src/lib/errors.ts`
+3. Add Paraglide translation key in `messages/{de,en,es}.json`
 
 ## Security / Permissions
 
-→ See [docs/ARCHITECTURE.md §Permission system](../docs/ARCHITECTURE.md#permission-system)
+Use `@RequirePermission` on controller methods or classes:
 
-**LLM reminder:** `@RequirePermission(Permission.WRITE_ALL)` is **required** on every `POST`, `PUT`, `PATCH`, `DELETE` endpoint — not optional. Do not mix with Spring Security's `@PreAuthorize`. Available permissions: `READ_ALL`, `WRITE_ALL`, `ADMIN`, `ADMIN_USER`, `ADMIN_TAG`, `ADMIN_PERMISSION`, `ANNOTATE_ALL`, `BLOG_WRITE`.
+```java
+@RequirePermission(Permission.WRITE_ALL)
+public Document updateDocument(...) { ... }
+```
+
+Available permissions: `READ_ALL`, `WRITE_ALL`, `ADMIN`, `ADMIN_USER`, `ADMIN_TAG`, `ADMIN_PERMISSION`
+
+`PermissionAspect` checks the current user's `UserGroup.permissions` at runtime.

-# audit
-
-Append-only event store for all domain mutations. Every write across the application produces an `audit_log` row. The activity feed and Family Pulse dashboard aggregate from this table.
-
-## What this domain owns
-
-Table: `audit_log` (append-only by convention — no UPDATE or DELETE in application code).
-Features: log mutations, query activity feed, query per-entity history.
-
-**Admission criteria (why this is cross-cutting, not a Tier-1 domain):** consumed by 5+ domains; has no user-facing CRUD of its own; the data model is fixed (event log, not a business entity).
-
-## What this domain does NOT own
-
-Nothing beyond the log table. `audit/` is an infrastructure layer, not a business domain.
-
-## Public surface (called from other domains)
-
-| Method | Consumer | Purpose |
-|---|---|---|
-| `logAfterCommit(event)` | document, person, user, ocr, geschichte | Record a mutation event after the DB transaction commits |
-
-`logAfterCommit` is the only write-path. Query paths (`AuditLogQueryService`) are consumed by `dashboard/` and the activity feed route.
-
-## Internal layout
-
-- `AuditService` — `logAfterCommit()` (write)
-- `AuditLogQueryService` — query by entity, by user, for the activity feed
-- `AuditLog` (entity) → table `audit_log`
-- `AuditLogRepository`
-
-## Cross-domain dependencies
-
-None. `audit/` is consumed by other domains; it does not call out to any of them.
-
-## Frontend counterpart
-
-No direct frontend counterpart. Audit data surfaces in the `activity/` and `conversation/` frontend domains via the dashboard API.

-# dashboard
-
-Stats aggregation for the admin dashboard and the Family Pulse widget. This is a derived domain — it has no tables of its own; all data is computed on-the-fly from Tier-1 domain data.
-
-## What this domain owns
-
-No entities. Routes: `/api/dashboard/*`, `/api/stats/*`.
-Features: document counts, person counts, publication stats, weekly activity data, incomplete-document list, enrichment queue, Family Pulse widget data, admin statistics.
-
-**Admission criteria (cross-cutting):** aggregates from 3+ domains; no owned entities.
-
-## What this domain does NOT own
-
-None of the underlying data — it reads from `document/`, `person/`, `audit/`, `notification/`, `geschichte/`.
-
-## Public surface
-
-`dashboard/` is a leaf domain — no other domain calls its services. It is the aggregator, not the aggregated.
-
-## Internal layout
-
-- `StatsController` — REST under `/api/stats`
-- `DashboardController` — REST under `/api/dashboard`
-- `StatsService` — aggregated counts (documents, persons, geschichten, incomplete, etc.)
-- `DashboardService` — activity feed composition, Family Pulse data
-
-## Cross-domain dependencies
-
-- `DocumentService.count()` — total document count (StatsService)
-- `DocumentService.getDocumentById(UUID)` / `getDocumentsByIds(List<UUID>)` — document enrichment for activity feed (DashboardService)
-- `PersonService.count()` — total person count (StatsService)
-- `TranscriptionService.listBlocks(UUID)` — transcription block lookup for resume widget (DashboardService)
-- `UserService.getById(UUID)` — actor name resolution in activity feed (DashboardService)
-- `CommentService.findAnnotationIdsByIds(...)` — annotation context lookup for activity feed (DashboardService)
-- `AuditLogQueryService.findMostRecentDocumentForUser()` / `getPulseStats()` / `findActivityFeed()` — audit-sourced feed rows (DashboardService)
-
-## Frontend counterpart
-
-Activity feed and Pulse widget are assembled in `frontend/src/lib/shared/dashboard/` and in the `aktivitaeten` route; no dedicated `dashboard/` lib folder.

-# document
-
-The archive's core concept. A `Document` represents one physical artefact (a letter, a postcard, a photo) stored in MinIO and described by metadata.
-
-## What this domain owns
-
-Entities: `Document`, `DocumentVersion`, `TranscriptionBlock`, `DocumentAnnotation`, `DocumentComment`.
-Features: document CRUD, file upload/download, full-text search, bulk editing, transcription workflows, annotation canvas, threaded comments, thumbnail generation (PDFBox).
-
-## What this domain does NOT own
-
-- `Person` (sender / receivers) — referenced by ID, resolved via `PersonService`
-- `Tag` — referenced by ID; the join is on the document side but tags are owned by `tag/`
-- `AppUser` — comments reference `AppUser` IDs, but user management lives in `user/`
-- OCR processing — `ocr/` orchestrates jobs; `ocr-service/` executes them
-
-## Public surface (called from other domains)
-
-| Method | Consumer | Purpose |
-|---|---|---|
-| `getDocumentById(UUID)` | ocr, notification | Fetch a single document |
-| `getDocumentsByIds(List<UUID>)` | ocr | Bulk fetch for OCR job |
-| `findByOriginalFilename(String)` | importing | Deduplication during mass import |
-| `deleteTagCascading(UUID tagId)` | tag | Remove a tag from all documents before deleting it |
-| `findWeeklyStats()` | dashboard | Activity data for Family Pulse widget |
-| `count()` | dashboard | Total document count for stats |
-| `addTrainingLabel(...)` | ocr | Attach a confirmed sender label to a document |
-| `findSegmentationQueue(int limit)` / `findTranscriptionQueue(int limit)` / `findReadyToReadQueue(int limit)` | ocr | OCR pipeline queues |
-
-## Internal layout
-
-- `DocumentController` — REST under `/api/documents`
-- `DocumentService` — CRUD, search (JPA Specifications), bulk edit
-- `DocumentRepository` — includes bidirectional conversation-thread query
-- `DocumentSpecifications` — composable `Specification` predicates for search
-- `DocumentVersionService` / `DocumentVersionRepository` — append-only version history
-- `ThumbnailService` + `ThumbnailAsyncRunner` — PDFBox thumbnail generation (separate thread pool)
-- Sub-packages: `annotation/`, `comment/`, `transcription/`
-
-## Cross-domain dependencies
-
-- `PersonService.getById()` / `getAllById()` — resolve sender and receivers
-- `TagService.expandTagNamesToDescendantIdSets()` — tag filter expansion
-- `FileService.uploadFile()` / `downloadFile()` / `generatePresignedUrl()` — S3 I/O
-- `NotificationService.notifyMentions()` / `.notifyReply()` — comment mentions
-- `AuditService.logAfterCommit()` — every mutation is audited

-# geschichte
-
-Family stories — curated narrative pieces that weave together persons, documents, and commentary into a publishable article. German: *Geschichte* (story / history).
-
-## What this domain owns
-
-Entity: `Geschichte`.
-Lifecycle: `DRAFT → PUBLISHED` (only published stories are visible to non-authors).
-Features: story CRUD, rich-text editing with person and document cross-references, publish/unpublish toggle, comment thread (shared component from `shared/discussion/`).
-
-## What this domain does NOT own
-
-- `Person` or `Document` records — stories reference them by ID. Deleting a Person or Document does not cascade to Geschichte.
-- Comment storage — shared comment infrastructure is in `document/comment/` (or `shared/discussion/` on the frontend).
-
-## Public surface (called from other domains)
-
-| Method | Consumer | Purpose |
-|---|---|---|
-| `getById(UUID)` | notification | Resolve story context in mention notifications |
-| `list(...)` | dashboard | Recent stories for the activity feed |
-| `count()` | dashboard | Published story count for stats |
-
-## Internal layout
-
-- `GeschichteController` — REST under `/api/geschichten`
-- `GeschichteService` — CRUD, publish lifecycle
-- `GeschichteRepository` — list by status, author
-
-## Cross-domain dependencies
-
-- `PersonService.getById()` / `getAllById()` — resolve person references in story body
-- `DocumentService.getDocumentsByIds()` — resolve document references in story body
-- `AuditService.logAfterCommit()` — story mutations are audited

-/**
- * Loads {@code canonical-documents.xlsx} into the document domain. Java performs no
- * semantic transformation: the normalizer already resolved people to slugs and dates to
- * ISO values. This loader maps columns by header name, routes each attribution
- * register-first (always retaining the raw cell in {@code sender_text}/{@code receiver_text}),
- * parses clean dates, and keeps the S3/thumbnail plumbing.
- *
- * <p>The import corpus is uniform — every PDF is named {@code <index>.pdf} flat in the import
- * dir — so a document's PDF is resolved <em>directly by its index</em>:
- * {@code importDir.resolve(index + ".pdf")}. The {@code index} is still hostile input
- * regardless of upstream trust (CWE-22 does not care it came from our Python tool): it is
- * validated against a strict catalog pattern with {@link #isValidImportIndex} (no path
- * separators, no {@code .}/{@code ..}, no absolute path, no slash homoglyphs) and the
- * resolved path is asserted to stay inside the import dir in {@link #resolvePdfByIndex} as
- * defense-in-depth. The {@code %PDF} magic-byte check still gates upload.

-
-## What this domain owns
-
-Entity: `Notification`.
-Features: create and deliver notifications, unread count, mark-read, SSE real-time push, per-user delivery preferences (stored as fields on `AppUser`, managed by `user/`).
-
-## What this domain does NOT own
-
-- `AppUser` (recipient) — owned by `user/`
-- `Document` or `Geschichte` (notification context) — referenced by ID only
-
-## Public surface (called from other domains)
-
-| Method | Consumer | Purpose |
-|---|---|---|
-| `notifyMentions(mentionedUserIds, comment)` | document (comment) | Push mention notifications when a comment contains @mentions |
-| `notifyReply(reply, participantIds)` | document (comment) | Push reply notification to all thread participants |
-| `countUnread(userId)` | user session | Unread badge count in the nav bar |
-| `getNotifications(userId)` | dashboard / activity | Notification list for bell dropdown |
-| `markRead(id)` / `markAllRead(userId)` | notification controller | User-driven read-state updates |
-| `updatePreferences(userId, dto)` | notification controller | Per-user delivery preferences |
-
-## Internal layout
-
-- `NotificationController` — REST under `/api/notifications`
-- `NotificationService` — create, query, mark-read
-- `SseEmitterRegistry` — runtime-stateful component that keeps one `SseEmitter` per connected user. On `notifyMentions()` / `notifyReply()`, the service writes to `SseEmitterRegistry` to push real-time events. SSE connections go **backend → browser directly**, not via the SvelteKit SSR layer.
-- `NotificationRepository` — persisted notification rows
-- `NotificationPreferenceDTO` — read/write DTO for preference endpoints (prefs stored on `AppUser`)

-
-OCR/HTR pipeline orchestration. This domain manages job lifecycle and result ingestion — it does **not** perform OCR. Actual text recognition runs in the Python `ocr-service/` container (port 8000, internal network only).
-
-## What this domain owns
-
-Entities: `OcrJob`, `OcrJobDocument`, `SenderModel`.
-Features: start OCR jobs, track job lifecycle (`PENDING → RUNNING → DONE / FAILED`), stream transcription blocks back into `document/transcription/`, sender-model training, segmentation training.
-
-## What this domain does NOT own
-
-- Document content — `Document` and `TranscriptionBlock` are owned by `document/`
-- File storage — presigned MinIO URLs are generated by `filestorage/FileService` and passed to the OCR service
-- OCR processing — the Python `ocr-service/` executes Surya (typewritten) and Kraken (Kurrent/Sütterlin HTR) and streams results back
-
-## Public surface (called from other domains)

-| Method | Consumer | Purpose |
-|---|---|---|
-| `startOcr(documentId, ...)` | document | Trigger an OCR job for a document |
-| `getJob(UUID)` | document | Fetch job status |

-- `OcrService` — job creation, presigned URL generation, result ingestion
-- `OcrBatchService` — batch job workflows

-- `OcrJobRepository` / `OcrJobDocumentRepository`
-- `SenderModelRepository` — trained sender-recognition models
-- `OcrClient` (interface) / `RestClientOcrClient` — HTTP client for the Python OCR service; mockable for tests

-# person
-
-Historical individuals referenced by documents. A `Person` is a family member who appears as a sender or receiver in the archive — they are never login accounts.
-
-## What this domain owns
-
-Entities: `Person`, `PersonNameAlias`, `PersonRelationship`.
-Features: person CRUD, name alias management, person merge (deduplication), family-member designation, relationship graph, person type classification (FAMILY, CORRESPONDENT, INSTITUTION).
-
-## What this domain does NOT own
-
-- `AppUser` — login accounts are in `user/`. A `Person` record has no login credentials. The separation is deliberate: a historical family member from 1905 is never a system user.
-- Document content — `Person` records are referenced by documents (as sender/receiver), not the other way around.
-- Relationship rendering — the Stammbaum view is derived by the frontend from `PersonRelationship` data.
-
-## Public surface (called from other domains)
-
-| Method | Consumer | Purpose |
-|---|---|---|
-| `getById(UUID)` | document, geschichte, ocr | Fetch one person by ID |
-| `getAllById(List<UUID>)` | document | Bulk fetch for sender/receiver resolution |
-| `findAll(String q)` | document, dashboard | List all persons |
-| `findByName(String firstName, String lastName)` | document | Filename-based **sender resolution** in `storeDocument`: exact-case match → single case-insensitive match → else **empty** (ambiguous names leave the sender unset; a null first name never matches). See ADR-033. |
-| `findOrCreateByAlias(String rawName)` | importing | Idempotent create during mass import; type classification happens internally. Resolves exact-case → lowest-id case-insensitive sibling → create — never throws on case-colliding aliases. See ADR-033. |
-| `findAllFamilyMembers()` | dashboard | Family member list for stats |
-| `findCorrespondents()` | document | Correspondent list for conversation filter |
-| `count()` | dashboard | Total person count for stats |
-
-## Internal layout
-
-- `PersonController` — REST under `/api/persons`
-- `PersonService` — CRUD, merge, alias management, family-member designation
-- `PersonRepository` — sorted list, name search
-- `PersonNameAlias` / `PersonNameAliasRepository` — alternative name spellings
-- `PersonNameParser` / `PersonTypeClassifier` — name parsing utilities
