Single pointer line at the top: humans read README.md, LLMs read CLAUDE.md.
No existing content removed — full migration is DOC-7's responsibility.

+## 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]
+}
+```

-# Builds and deploys the staging environment from main every night.
-# Runs on the self-hosted runner using Docker-out-of-Docker (the docker
-# socket is mounted in), so `docker compose build` produces images on
-# the host daemon and `docker compose up` consumes them directly — no
-# registry hop.
-#
-# Operational assumptions (see docs/DEPLOYMENT.md §3 for the full setup):
-#
-#   1. Single-tenant self-hosted runner. The "Write staging env file" step
-#      writes every secret to .env.staging on the runner filesystem; the
-#      `if: always()` cleanup step removes it. A multi-tenant runner
-#      would need to switch to docker compose --env-file <(stdin) instead.
-#
-#   2. Host docker layer cache is authoritative. There is no
-#      actions/cache; we rely on the host daemon to keep Maven and npm
-#      layers warm between runs. A `docker system prune` on the host
-#      will cause the next nightly build to be cold (5–10 min slower).

-# Builds and deploys the production environment on `v*` tag push.
-# Runs on the self-hosted runner via Docker-out-of-Docker; images are
-# tagged with the actual git tag (e.g. v1.0.0) so rollback is
-#   `TAG=<previous> docker compose -f docker-compose.prod.yml -p archiv-production up -d --wait`
-#
-# Operational assumptions (see docs/DEPLOYMENT.md §3 for the full setup):
-#
-#   1. Single-tenant self-hosted runner. The "Write production env file"
-#      step writes every secret to .env.production on the runner
-#      filesystem; the `if: always()` cleanup step removes it. A
-#      multi-tenant runner would need to switch to
-#      `docker compose --env-file <(stdin)` instead.
-#
-#   2. Host docker layer cache is authoritative. There is no
-#      actions/cache; we rely on the host daemon to keep Maven and npm
-#      layers warm between runs. A `docker system prune` on the host
-#      will cause the next release build to be cold (5–10 min slower).

-# Production environment:

+- `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`.
+```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 }) => {
+    default: async ({ request, fetch }) => {
-    const formData = await request.formData();
+        const formData = await request.formData();
-    const name = formData.get("name") as string;
+        const name = formData.get('name') as string;  // cast needed — FormData returns FormDataEntryValue
-    // ...
+        // ...
-    return fail(400, { error: "message" }); // on error
+        return fail(400, { error: 'message' });  // on error
-    throw redirect(303, "/target"); // on success
+        throw redirect(303, '/target');           // on success
-  },
+    }
 };
 ```
 
 ### Date Handling
 
-→ See [CONTRIBUTING.md §Date handling](./CONTRIBUTING.md#date-handling)
+- **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:
-**LLM reminder:** always append `T12:00:00` when constructing `new Date()` from an ISO date string — prevents UTC timezone off-by-one errors.
+  ```typescript
+  new Intl.DateTimeFormat('de-DE', { day: 'numeric', month: 'long', year: 'numeric' })
+      .format(new Date(doc.documentDate + 'T12:00:00'))
+  ```
 
 ### UI Component Library
 
-→ See per-domain READMEs: [`frontend/src/lib/person/README.md`](./frontend/src/lib/person/README.md), [`frontend/src/lib/tag/README.md`](./frontend/src/lib/tag/README.md), [`frontend/src/lib/document/README.md`](./frontend/src/lib/document/README.md), [`frontend/src/lib/shared/README.md`](./frontend/src/lib/shared/README.md)
+Custom components in `src/lib/components/`:
+
+| Component | Props | Description |
+|---|---|---|
+| `PersonTypeahead` | `name`, `label`, `value`, `initialName`, `on:change` | Single-person selector with typeahead dropdown |
+| `PersonMultiSelect` | `selectedPersons` (bind) | Chip-based multi-person selector |
+| `TagInput` | `tags` (bind), `allowCreation?`, `on:change` | Tag chip input with typeahead |

+- `font-serif` (Merriweather) — body text, document titles, names
-- `font-serif` (Tinos) — 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">
+<div class="bg-white shadow-sm border border-brand-sand rounded-sm p-6">
-    <h2 class="text-xs font-bold uppercase tracking-widest text-ink-3 mb-5">Section Title</h2>
+    <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

 ### Error Handling (Frontend)
 
-→ See [CONTRIBUTING.md §Error handling](./CONTRIBUTING.md#error-handling)
+`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`
-**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`.
+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)
+The `docker-compose.yml` at the repo root orchestrates everything. A MinIO MC helper container runs at startup to create the `archive-documents` bucket. The backend container depends on both `db` and `minio` being healthy.
+
+Database migrations live in `backend/src/main/resources/db/migration/` (Flyway, SQL files named `V{n}__{description}.sql`).

-## 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 raw `fetch` — the client cannot handle it.
-
-### 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'))` |
-
-### 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

+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

-# 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.

-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

- * Promotes the {@code auth_token} cookie to an {@code Authorization} header

- * SSR fetches do.
- *
- * <p>The SvelteKit login action stores the full HTTP Basic header value
- * ({@code "Basic <base64>"}) in an HttpOnly cookie. SSR fetches from
- * {@code hooks.server.ts} read the cookie and pass it explicitly as the
- * {@code Authorization} header. In the dev environment, Vite's proxy does
- * the same on every {@code /api/*} request (see {@code vite.config.ts}).
- * In production, Caddy proxies {@code /api/*} straight to the backend and
- * does NOT translate the cookie — so client-side {@code fetch} and
- * {@code EventSource} calls reach the backend without auth, get
- * {@code 401 WWW-Authenticate: Basic}, and the browser pops a native dialog.
- *
- * <p>This filter closes that gap: if a request has an {@code auth_token}
- * cookie but no explicit {@code Authorization} header, promote the cookie
- * value (URL-decoded) into the header before Spring Security inspects it.
- * Explicit {@code Authorization} headers are preserved unchanged.
- *
- * <p>See #520. Filter runs at {@code Ordered.HIGHEST_PRECEDENCE} so it
- * mutates the request before any Spring Security filter sees it.
- *
- * <p><b>Scope:</b> only {@code /api/*} requests are touched. The
- * {@code /actuator/*} block in Caddy plus the open auth/reset paths in
- * {@link SecurityConfig} must NOT receive a promoted Authorization.
- *
- * <p><b>⚠ Log-leakage warning:</b> the wrapped request exposes the
- * Authorization header via {@code getHeaderNames}/{@code getHeaders}. Any
- * filter or interceptor that iterates request headers will see the live
- * Basic credential. Do NOT add a request-header logger downstream of this

-# user
-
-Login accounts and permission groups. An `AppUser` is a system user who can authenticate and act in the application — they are never a historical family member.
-
-## What this domain owns
-
-Entities: `AppUser`, `UserGroup`, password-reset tokens, invite tokens.
-Features: user CRUD, group CRUD, password change, password reset flow, invite links.
-
-## What this domain does NOT own
-
-- `Person` records — historical family members. An `AppUser` is never linked to a `Person`. This separation is intentional: a person who digitized letters in 2024 is not the same entity as their great-grandmother who wrote them in 1912. See `docs/GLOSSARY.md`.
-- Permission enforcement — `security/` owns `@RequirePermission` and `PermissionAspect`. `user/` only manages which permissions are stored on `UserGroup`.
-
-## Public surface
-
-`UserService` methods are consumed primarily by the security infrastructure and the admin UI. No other business-logic domain calls `UserService` directly.
-
-The Spring Security chain (via `CustomUserDetailsService` in `security/`) calls `AppUserRepository.findByUsername()` on every authenticated request.
-
-## Internal layout
-
-- `UserController` — REST under `/api/users` (current user, CRUD)
-- `AuthController` — password reset, invite flow
-- `UserService` — BCrypt-encoded passwords, group assignment
-- `AppUserRepository` — find by username (used by Spring Security)
-- `UserGroupRepository` — group and permission management
-
-## Cross-domain dependencies
-
-- `AuditService.logAfterCommit()` — user-management mutations are audited
-
-## Frontend counterpart

-# Familienarchiv — Architecture
-
-**Target reader:** a PM-with-CS background who has read the README.
-**Goal:** accurate mental model after one read — enough to sketch the system on a whiteboard.
-
-For domain terminology, see [docs/GLOSSARY.md](GLOSSARY.md).
-For security policies and hardening, see [docs/security-guide.md](security-guide.md).
-For low-level ADR details, see [docs/adr/](adr/).

-## 1. High-level diagram
-
-The updated container diagram below shows all six deployable units and their communication paths.
-
-See [docs/architecture/c4-diagrams.md](architecture/c4-diagrams.md) for the full C4 L1/L2/L3 diagrams (Mermaid, Gitea-rendered).
-
-Key points not visible in the diagram:
-
-- **OCR network boundary:** the OCR service has no external port — it is reachable only on the internal Docker Compose network. Only the backend calls it. The OCR service fetches PDF files from MinIO using a presigned URL that the backend generates and passes in the request body; the PDF bytes never pass through the backend.
-- **SSE path:** server-sent event notifications go directly from the backend to the user's browser (not via the SvelteKit SSR layer) over a long-lived HTTP connection managed by `SseEmitterRegistry`.
-
----
-
-## 2. Domain set
-
-Both stacks are organised **package-by-domain**: each domain owns its entities, service, controller, repository, and DTOs. Domain names are identical across `backend/src/main/java/.../` and `frontend/src/lib/`.
-
-### Tier-1 domains — have entities and user-facing CRUD
-
-**`document`** — the archive's core concept. Owns `Document`, `DocumentVersion`, `TranscriptionBlock`, `DocumentAnnotation`, `DocumentComment`. Does NOT own persons or tags (references them by ID). Cross-domain deps: `person` (sender/receivers), `tag` (labels), `ocr` (HTR pipeline), `notification` (comment mentions), `audit` (every mutation).
-
-**`person`** — historical individuals referenced by documents. Owns `Person`, `PersonNameAlias`, `PersonRelationship`. Does NOT own `AppUser` (login accounts are a separate domain). Cross-domain deps: `document` (relationship queries).
-
-**`tag`** — hierarchical document categories. Owns `Tag` (self-referencing `parent_id` tree). Does NOT own documents; the join is document-side. No cross-domain deps.
-
-**`user`** — login accounts and permission groups. Owns `AppUser`, `UserGroup`, invite tokens. Does NOT own `Person` records. Cross-domain deps: `audit` (user management events).
-
-**`geschichte`** — family stories. Owns `Geschichte` (`DRAFT → PUBLISHED` lifecycle). Cross-domain deps: `person`, `document` (linked entities in the story body).
-
-**`notification`** — in-app messages. Owns `Notification`. Delivers via `SseEmitterRegistry` (live) and persisted rows (bell dropdown). Cross-domain deps: `user` (recipient), `document` (context).
-
-**`ocr`** — OCR/HTR pipeline orchestration. Owns `OcrJob`, `OcrJobDocument`, `SenderModel`. Calls the Python OCR service; maps streamed transcription blocks back to `document`. Cross-domain deps: `document` (target), `filestorage` (presigned URLs).
-
-### Tier-2 domains — derived (UI without dedicated tables)
-
-A **derived domain** has its own routes and UI but no database tables of its own; it is assembled from data owned by Tier-1 domains.
-
-**`conversation`** (route: `/briefwechsel`) — bilateral letter timeline between two `Person`s. Derived from `Document` sender/receiver relationships. The `DocumentRepository` bidirectional query is the only data source.
-
-**`activity`** (route: `/aktivitaeten`) — family activity feed. Derived from `audit_log`, `notifications`, and document events. No aggregation table; computed on-the-fly by `DashboardService` and composed in the SvelteKit load function.
-
----
-
-## 3. Cross-cutting layer
-
-Members of the cross-cutting layer have no entity of their own, no user-facing CRUD, and are consumed by two or more domains — or are framework infrastructure that every domain depends on.
-
-| Member (backend package) | Purpose | Admission criteria |
-|---|---|---|
-| `audit` | Append-only event store (`audit_log`) for all domain mutations. Feeds the activity feed and Family Pulse dashboard. | Consumed by 5+ domains; no user-facing CRUD of its own |
-| `config` | Infrastructure bean definitions: `MinioConfig`, `AsyncConfig`, `WebConfig` | Framework infra; no business logic |
-| `dashboard` | Stats aggregation for the admin dashboard and Family Pulse widget | Aggregates from 3+ domains; no owned entities |
-| `exception` | `DomainException`, `ErrorCode` enum, `GlobalExceptionHandler` | Framework infra; consumed by every controller and service. Adding a new `ErrorCode` requires matching updates in `frontend/src/lib/shared/errors.ts` and all three `messages/*.json` locale files. |
-| `filestorage` | `FileService` — MinIO/S3 upload, download, presigned-URL generation | Generic service; consumed by `document` and `ocr` |
-| `importing` | `MassImportService` — async ODS/Excel batch import | Orchestrates across `person`, `tag`, `document` |
-| `security` | `SecurityConfig`, `Permission` enum, `@RequirePermission` annotation, `PermissionAspect` (AOP) | Framework infra; enforced globally across all controllers |
-
-**Frontend `shared/`** follows the same admission criteria. Key members: `api.server.ts` (typed openapi-fetch client factory), `errors.ts` (backend `ErrorCode` → i18n mapping), `shared/primitives/` (generic UI components used across ≥2 domains), `shared/discussion/` (comment/mention editor used by `document` and `geschichte`), `shared/utils/` (pure date/sort/debounce utilities).
-
----
-
-## 4. Stack-symmetry principle
-
-**Rule:** a domain has the same name on both stacks.
-
-| Backend | Frontend |
-|---|---|
-| `backend/src/main/java/.../document/` | `frontend/src/lib/document/` |
-| `backend/src/main/java/.../person/` | `frontend/src/lib/person/` |
-| … | … |
-
-Adding a new Tier-1 domain means creating a package on **both** sides under the same name. Adding only a backend package without a corresponding frontend folder (or vice versa) is a red flag in code review.
-
-The backend has been domain-first since the project started. The frontend `src/lib/` was restructured from flat-by-type to domain-first in issue #408 (May 2026).
-

-
-## 5. Key architectural decisions
-
-### ADR-001 — OCR as a Python microservice
-The two OCR engines required (Surya for typewritten text, Kraken for Kurrent/Sütterlin HTR) exist only in the Python ecosystem. A separate `ocr-service` Python container exposes a simple HTTP API; the Spring Boot backend calls it via `RestClient`. All job tracking and business logic remain in Spring Boot. See [ADR-001](adr/001-ocr-python-microservice.md).
-
-### ADR-002 — Polygon JSONB storage for annotations
-Kraken outputs polygon boundaries for historical handwriting; axis-aligned bounding boxes approximate them poorly. Annotation and transcription-block positions are stored as `polygon JSONB` columns. Display-only — server-side geometry continues to use the AABB fields. See [ADR-002](adr/002-polygon-jsonb-storage.md).
-
-### ADR-003 — Unified activity feed (Chronik/Aktivität)
-Personal notifications and ambient activity (uploads, transcriptions, comments) are merged into one `/aktivitaeten` page. The SvelteKit load function composes data from `/api/dashboard/activity` and `/api/notifications` — no new backend orchestrator endpoint. See [ADR-003](adr/003-chronik-unified-activity-feed.md).
-
-### ADR-004 — In-process PDFBox thumbnails
-Thumbnails are rendered in Spring Boot using Apache PDFBox (already a dependency) rather than delegating to the OCR service. A dedicated `thumbnailExecutor` pool isolates the work. See [ADR-004](adr/004-pdfbox-thumbnails.md).
-
-### ADR-005 — thumbnailAspect + pageCount
-Aspect ratio (`PORTRAIT` / `LANDSCAPE`) and page count are persisted alongside the thumbnail JPEG at generation time — cheap to derive then, expensive to re-derive later. See [ADR-005](adr/005-thumbnail-aspect-and-page-count.md).
-
-### ADR-006 — Synchronous domain events inside the publisher's transaction
-When a `Person` display name changes, all `TranscriptionBlock` `@mention` text must be rewritten atomically. This is done via Spring `ApplicationEventPublisher` + `@EventListener @Transactional` to avoid a circular dependency between `PersonService` and `TranscriptionBlockService`. See [ADR-006](adr/006-synchronous-domain-events-in-transaction.md).
-
-### Layering rule
-```
-Controller → Service → Repository → DB
-```
-Controllers never call repositories directly. Services never reach into another domain's repository — they call the other domain's service. This keeps domain boundaries clear and business logic testable without a running database.
-
-### Permission system
-Permissions are enforced via `@RequirePermission(Permission.X)` on controller methods, checked at runtime by `PermissionAspect` (Spring AOP). The `Permission` enum defines the available capabilities (`READ_ALL`, `WRITE_ALL`, `ADMIN`, `ADMIN_USER`, `ADMIN_TAG`, `ADMIN_PERMISSION`, `ANNOTATE_ALL`, `BLOG_WRITE`). This is not Spring Security's `@PreAuthorize` — do not mix the two mechanisms.
-
-Sessions use a Base64-encoded Basic Auth token stored in an `httpOnly`, `SameSite=strict` cookie (`auth_token`, maxAge=86400 s). CSRF protection is disabled because this cookie configuration structurally prevents cross-origin credential theft. See [docs/security-guide.md](security-guide.md) for the full security reference.
-
----
-
-## 6. Data flow walkthroughs
-
-### Document upload
-
-1. User submits the edit form (file + metadata) from the browser.
-2. The SvelteKit server action sends `PUT /api/documents/{id}` as `multipart/form-data`. `hooks.server.ts` (`handleFetch`) transparently injects the `Authorization` header from the `auth_token` cookie — the action itself is unaware of auth.
-3. `PermissionAspect` intercepts the controller method, verifies the user has `WRITE_ALL`, and proceeds.
-4. `DocumentController` delegates to `DocumentService.updateDocument()`.
-5. `DocumentService` resolves the `Person` sender by ID (via `PersonService`), resolves or creates `Tag`s (via `TagService`), then calls `FileService.uploadFile()`.
-6. `FileService` generates a key (`documents/{UUID}_{filename}`), streams the file to MinIO via the AWS SDK v2 S3Client.
-7. `DocumentService` persists the S3 key, sets `status = UPLOADED`, and saves to PostgreSQL.
-8. `AuditService` writes an `UPLOADED` event to `audit_log` in the same transaction.
-9. Backend returns the updated `Document` JSON; SvelteKit refreshes the document detail page.
-
-### Transcription block autosave
-
-1. The transcriber pauses typing; the frontend's `useBlockAutoSave` factory fires after a debounce interval.
-2. The browser sends `PUT /api/documents/{documentId}/transcription-blocks/{blockId}` with the new text and the block's current `version` (optimistic lock). `hooks.server.ts` (`handleFetch`) injects the `Authorization` header from the cookie.
-3. `TranscriptionService.saveBlock()` loads the block, checks the `@Version` field for concurrent edits, updates `block.text` and any `@mention` sidecars, and calls `saveAndFlush`.
-4. If a concurrent save collides (version mismatch), the backend returns `409 Conflict`; the frontend's `saveBlockWithConflictRetry` helper re-fetches and retries.
-5. On success, `AuditService` logs a `BLOCK_SAVED` event.
-6. If the block text contains a new `@PersonName` mention, `NotificationService` creates a `Notification` row for the mentioned person's `AppUser`.
-7. `SseEmitterRegistry` broadcasts the notification over the open SSE connection to that user's browser in real time.

+## Overview
 
-**LLM reminder:** ADRs are sequential — use the next number after the highest existing one in `docs/adr/`. When making a significant architectural change (new service, data model change, technology swap), write a new ADR before implementing.
+Project documentation organized into four categories: architecture decision records (ADRs), system architecture diagrams, infrastructure runbooks, and detailed UI/UX specifications.
+
+## Folder Structure
+
+```
+docs/
+├── adr/                     # Architecture Decision Records
+├── architecture/            # C4 model diagrams and system architecture docs
+├── infrastructure/          # Deployment, CI/CD, and ops guides

+└── TODO-frontend.md         # Frontend backlog
+```
+
+## ADR (`adr/`)
+
+Architecture Decision Records capture major technical decisions and their rationale.
+
+| ADR | Title | Status |
+|---|---|---|
+| `001-ocr-python-microservice.md` | OCR as a separate Python container | Accepted |
+| `002-polygon-jsonb-storage.md` | Polygon coordinates in JSONB columns | Accepted |
+| `003-chronik-unified-activity-feed.md` | Unified activity feed (Chronik) | Accepted |
+
+When making a significant architectural change (new service, data model change, technology swap), write a new ADR following the format:
+- Status (Proposed / Accepted / Deprecated / Superseded)
+- Context (forces at play)
+- Decision (what we decided)
+- Consequences (trade-offs)
+- Alternatives Considered (table format)
+
+## Architecture (`architecture/`)
+
+Contains C4 model diagrams describing the system at different zoom levels:
+
+- **Context diagram** — How Familienarchiv fits into the user and system ecosystem
+- **Container diagram** — The high-level technology choices (Spring Boot, SvelteKit, PostgreSQL, MinIO, OCR service)
+- **Component diagram** — Major structural components within the backend
+
+Written in Markdown with embedded Mermaid or PlantUML diagrams (`c4-diagrams.md`).
+
+## Infrastructure (`infrastructure/`)
+
+Operational documentation for running Familienarchiv in production and CI.
+
+| Document | Purpose |
+|---|---|
+| `ci-gitea.md` | Gitea CI/CD pipeline configuration |
+| `production-compose.md` | Production Docker Compose setup |
+| `s3-migration.md` | Migrating documents between S3 buckets |
+| `self-hosted-catalogue.md` | Self-hosted software catalogue |
+
+## Specs (`specs/`)
+
+High-fidelity UI/UX specifications written as standalone HTML files. These are design documents that describe exact layout, interactions, and responsive behavior before implementation.
+
+Each spec typically includes:
+- Visual mockups with CSS-in-HTML styling
+- Interaction flows and state transitions
+- Responsive breakpoint behavior
+- Accessibility requirements
+
+Examples of active spec areas:
+- Document detail page (`document-topbar-*.html`, `documents-page-spec.html`)
+- Admin interfaces (`admin-redesign-*.html`, `admin-tag-overhaul.html`)
+- Transcription workflows (`inline-transcription-*.html`, `annotation-transcription-*.html`)
+- Dashboard and activity feeds (`dashboard-*.html`, `chronik-spec.html`)
+- OCR admin (`ocr-admin-spec.html`)
+
+## How to Use
+
+1. **Before implementing a feature**, check `specs/` for an existing specification.
+2. **When proposing a new architecture**, draft an ADR in `adr/` and discuss before coding.
+3. **When deploying**, follow `infrastructure/production-compose.md`.
+4. **Keep TODO files updated** — they serve as lightweight backlogs.
+
+## Style Guide
+
+`STYLEGUIDE.md` covers:
+- Code formatting and linting rules
+- Component naming conventions
+- Color palette and typography
+- Accessibility standards (WCAG 2.1 AA)
+
+## Contributing
+
+- ADRs should be sequential (`NNN-descriptive-name.md`).
+- Specs should be self-contained HTML files viewable in a browser.
+- Infrastructure docs should include copy-pasteable commands.

-
-```mermaid
-graph TD
-    Browser -->|HTTPS| Caddy["Caddy (TLS termination)"]
-    Caddy -->|HTTP :3000| Frontend["Web Frontend\nSvelteKit Node adapter"]
-    Caddy -->|HTTP :8080| Backend["API Backend\nSpring Boot / Jetty :8080"]

-    Caddy -->|SSE proxy_pass| Backend
-```
-
-**Key facts:**
-- Caddy terminates TLS and reverse-proxies to frontend (`:3000`) and backend (`:8080`). The Caddyfile is committed at [`infra/caddy/Caddyfile`](../infra/caddy/Caddyfile) and is installed on the host as `/etc/caddy/Caddyfile` (symlink).
-- The host binds all docker-published ports to `127.0.0.1` only; Caddy is the sole external entry point.
-- The OCR service has **no published port** — reachable only on the internal Docker network from the backend.
-- SSE notifications transit Caddy (browser → Caddy → backend); the backend is never reachable directly from the public internet. The SvelteKit SSR layer is bypassed for SSE, but Caddy is not.
-- The Caddyfile responds `404` on `/actuator/*` (defense in depth). Internal monitoring scrapes the backend on the docker network, not through Caddy.
-- Production and staging cohabit on the same host via docker compose project names: `archiv-production` (ports 8080/3000) and `archiv-staging` (ports 8081/3001).
-
-### OCR memory requirements
-
-The OCR service requires significant RAM for model loading. The dev compose sets `mem_limit: 12g`.
-
-| Production target | RAM | Recommended OCR limit | Notes |
-|---|---|---|---|
-| Hetzner CX42 | 16 GB | 12 GB | Recommended for OCR-enabled production |
-| Hetzner CX32 | 8 GB | 6 GB | Accept reduced batch sizes and slower throughput |
-| Hetzner CX22 | 4 GB | — | Disable the OCR service (`profiles: [ocr]`); run OCR on demand only |
-
-A CX32 cannot honour the default `mem_limit: 12g` — set the `OCR_MEM_LIMIT=6g` env var (in `.env.production` / `.env.staging`, or as a Gitea secret consumed by the workflow) before deploying on a CX32. The prod compose interpolates this var with a 12g default.
-
-### Dev vs production differences
-
-| Concern | Dev (`docker-compose.yml`) | Prod (`docker-compose.prod.yml`) |
-|---|---|---|
-| MinIO image tag | `minio/minio:latest` | Pinned `minio/minio:RELEASE.…` |
-| Data persistence | Bind mounts `./data/postgres`, `./data/minio` | Named Docker volumes (`postgres-data`, `minio-data`) |
-| MinIO credentials for backend | Root user/password | Service account `archiv-app` with bucket-scoped rights |
-| Bucket creation | `create-buckets` helper | Same helper, plus service-account bootstrap on every up |
-| Spring profile | `dev,e2e` (Swagger + e2e overrides) | unset — base `application.yaml` is production-ready |
-| Mail | Mailpit (local catcher) | Real SMTP (production) / Mailpit via `profiles: [staging]` (staging) |
-| Frontend image | Dev server, `target: development`, port 5173 | Node adapter, `target: production`, port 3000 |
-| Host port binding | All published | Bound to `127.0.0.1` only; Caddy is the front door |
-| Deploy method | `docker compose up -d` (manual) | Gitea Actions: `nightly.yml` (staging, cron) and `release.yml` (production, on `v*` tag) — both use `up -d --wait` |
-
-Full prod compose: [`docker-compose.prod.yml`](../docker-compose.prod.yml). Workflow files: [`.gitea/workflows/nightly.yml`](../.gitea/workflows/nightly.yml), [`.gitea/workflows/release.yml`](../.gitea/workflows/release.yml).
-
----
-
-## 2. Environment variables
-
-All vars are set in `.env` at the repo root (copy from `.env.example`). The backend resolves them via `application.yaml`; the Docker Compose file wires them into each container.
-
-**Any var found in `docker-compose.yml` or `application*.yaml` that is not in this table is a blocking review comment on any PR that changes those files.**

-## 3. Bootstrap from scratch
-
-Production and staging deploy via Gitea Actions (`release.yml` on `v*` tag, `nightly.yml` on cron). The server itself only needs to host Caddy, Docker, and the runner — the workflows handle the rest.
-
-### 3.1 Server one-time setup
-
-```bash
-# Base hardening
-ufw default deny incoming && ufw allow 22/tcp && ufw allow 80/tcp && ufw allow 443/tcp && ufw enable
-# /etc/ssh/sshd_config: PasswordAuthentication no, PermitRootLogin no
-
-# Install Caddy 2 (https://caddyserver.com/docs/install#debian-ubuntu-raspbian)
-apt install caddy
-
-# Use the Caddyfile from the repo (replace path with the runner's clone target)
-# CI DEPENDENCY: the nightly and release workflows run `systemctl reload caddy` to
-# pick up committed Caddyfile changes. They find the file via this symlink — if it
-# is absent or points elsewhere, the reload succeeds but serves stale config.
-ln -sf /opt/familienarchiv/infra/caddy/Caddyfile /etc/caddy/Caddyfile
-systemctl reload caddy
-
-# fail2ban — protect /api/auth/login from credential stuffing.
-# Jail watches the Caddy JSON access log for 401 responses on
-# /api/auth/login. The jail (maxretry=10 / findtime=10m / bantime=30m)
-# and filter are committed under infra/fail2ban/ — symlink them in:
-apt install fail2ban
-ln -sf /opt/familienarchiv/infra/fail2ban/jail.d/familienarchiv.conf \
-       /etc/fail2ban/jail.d/familienarchiv.conf
-ln -sf /opt/familienarchiv/infra/fail2ban/filter.d/familienarchiv-auth.conf \
-       /etc/fail2ban/filter.d/familienarchiv-auth.conf
-systemctl reload fail2ban
-# Verify after first deploy with:
-#   fail2ban-client status familienarchiv-auth
-#   fail2ban-regex /var/log/caddy/access.log familienarchiv-auth
-
-# Tailscale — used by the backup pipeline to reach heim-nas (follow-up issue)
-curl -fsSL https://tailscale.com/install.sh | sh && tailscale up
-
-# Self-hosted Gitea runner — register against the repo with a runner token.
-# This runner is assumed single-tenant: the deploy workflows write .env.*
-# files to disk during execution (cleaned up unconditionally on completion).
-# A multi-tenant runner would need to switch to stdin-piped env files.
-# (See https://docs.gitea.com/usage/actions/quickstart for the register step.)

-staging.raddatz.cloud  A   <server IP>
-git.raddatz.cloud      A   <server IP>

-
-### 3.3 Gitea secrets (Repo → Settings → Actions → Secrets)
-
-| Secret | Used by | Notes |
-|---|---|---|
-| `PROD_POSTGRES_PASSWORD` | release.yml | strong unique password |
-| `PROD_MINIO_PASSWORD` | release.yml | MinIO root password; used only at bootstrap |
-| `PROD_MINIO_APP_PASSWORD` | release.yml | application service-account password |
-| `PROD_OCR_TRAINING_TOKEN` | release.yml | `python3 -c "import secrets; print(secrets.token_hex(32))"` |
-| `PROD_APP_ADMIN_USERNAME` | release.yml | e.g. `admin@archiv.raddatz.cloud` |
-| `PROD_APP_ADMIN_PASSWORD` | release.yml | **⚠ locked permanently on first deploy** — see §3.5 |
-| `STAGING_POSTGRES_PASSWORD` | nightly.yml | different from prod |
-| `STAGING_MINIO_PASSWORD` | nightly.yml | different from prod |
-| `STAGING_MINIO_APP_PASSWORD` | nightly.yml | different from prod |
-| `STAGING_OCR_TRAINING_TOKEN` | nightly.yml | different from prod |
-| `STAGING_APP_ADMIN_USERNAME` | nightly.yml | e.g. `admin@staging.raddatz.cloud` |
-| `STAGING_APP_ADMIN_PASSWORD` | nightly.yml | locked on first staging deploy |
-| `MAIL_HOST` | release.yml | SMTP relay hostname (prod only) |
-| `MAIL_PORT` | release.yml | typically `587` |
-| `MAIL_USERNAME` | release.yml | SMTP user |
-| `MAIL_PASSWORD` | release.yml | SMTP password |
-
-### 3.4 First deploy
-
-```bash
-# 1. Trigger nightly.yml manually (Repo → Actions → nightly → "Run workflow")
-#    Expected: docker compose up -d --wait succeeds for archiv-staging, then
-#    the workflow's "Smoke test deployed environment" step asserts:
-#      - https://staging.raddatz.cloud/login returns 200
-#      - HSTS header is present
-#      - /actuator/health returns 404 (defense-in-depth check)
-# 2. (Optional) Re-verify manually
-curl -I https://staging.raddatz.cloud/
-#    Expected: 200 (login page) with HSTS + X-Content-Type-Options headers
-# 3. When staging looks healthy, push a v* tag to trigger release.yml
-git tag v1.0.0 && git push origin v1.0.0
-```
-
-### 3.5 ⚠ Admin password is locked on first deploy
-
-`UserDataInitializer` creates the admin user **only if the email does not exist**. The first successful deploy persists the admin password to the database. Changing `PROD_APP_ADMIN_PASSWORD` in Gitea secrets after that point has **no effect** — the secret is only consulted when the row is missing.
-
-Before the first deploy: rotate `PROD_APP_ADMIN_PASSWORD` to a strong value. After the first deploy: change the admin password via the in-app account settings, not via the Gitea secret.

-
-## 4. Logs + observability
-
-### First-response commands
-
-```bash
-# Stream backend logs (most useful first)
-docker compose logs --follow --tail=100 backend
-
-# Stream all services
-docker compose logs --follow
-
-# Single snapshot
-docker compose logs --tail=200 <service>
-# services: frontend, backend, db, minio, ocr-service
-```
-
-### Log locations
-
-- **Backend application log**: stdout (captured by Docker). Access inside the container at `/app/logs/` via `docker exec`.
-- **Spring Actuator health**: `http://localhost:8080/actuator/health` (internal only in prod — port 8081 for Prometheus scraping)
-- **Prometheus scraping**: management port 8081, path `/actuator/prometheus`. Internal only; Caddy blocks `/actuator/*` externally.
-
-### Future observability
-
-Phase 7 of the Production v1 milestone adds Prometheus + Loki + Grafana. No monitoring infrastructure is in place yet.
-
----
-
-## 5. Backup + recovery
-
-### Current state — no automated backup
-
-No automated backup is configured. Manual procedure for a point-in-time backup:
-
-```bash
-# PostgreSQL dump
-docker exec archive-db pg_dump -U ${POSTGRES_USER} ${POSTGRES_DB} > backup-$(date +%Y%m%d).sql
-
-# MinIO data (bind-mounted in dev)
-# Copy ./data/minio/ to external storage
-```
-
-Restoration:
-```bash
-# Restore Postgres
-docker exec -i archive-db psql -U ${POSTGRES_USER} ${POSTGRES_DB} < backup-YYYYMMDD.sql
-```
-
-### Planned — phase 5 of Production v1 milestone
-
-Automated backup (nightly `pg_dump` + MinIO `mc mirror` over Tailscale to `heim-nas`) is a follow-up issue. Until that ships: **manual backups are the only recovery option.**
-
-### Rollback
-
-Each release tag corresponds to a docker image tag on the host daemon (built via DooD; no registry). Rolling back to a previous tag is one command:
-
-```bash
-TAG=v1.0.0 docker compose \
-  -f docker-compose.prod.yml \
-  -p archiv-production \
-  --env-file /opt/familienarchiv/.env.production \
-  up -d --wait --remove-orphans
-```
-
-If the rollback target image is no longer present on the host (host disk pruned, etc.), re-trigger `release.yml` for that tag from Gitea Actions UI — it rebuilds and redeploys.
-
-**Flyway migrations are not auto-rolled-back.** If a release contained a destructive migration (drop column, rename table), a tag rollback brings the schema back to a previous app version but the data shape has already changed. For breaking schema changes, prefer a forward-only fix.
-
----
-
-## 6. Common operational tasks
-
-### Reset dev database (truncates data, keeps schema)
-
-```bash
-bash scripts/reset-db.sh
-```
-
-> Truncates all data but does **not** drop the schema or re-run Flyway. Use for E2E test resets, not full reinstalls.
-> ⚠️ Script hardcodes `DB_USER=archive_user` and `DB_NAME=family_archive_db` — if you customised these in `.env`, edit the script accordingly.
-
-### Rebuild frontend container (clears node_modules volume)
-
-```bash
-bash scripts/rebuild-frontend.sh
-```
-
-> Assumes the Docker Compose volume is named `familienarchiv_frontend_node_modules`. If your project directory is not named `familienarchiv`, edit line 16 of the script.
-
-### Download Kraken OCR models
-
-```bash
-bash scripts/download-kraken-models.sh
-```
-
-> Downloads the Kurrent/Sütterlin HTR models. Run once after a fresh clone or when models are updated.
-
-### Trigger a mass import (Excel/ODS)
-
-**Dev:** drop the ODS spreadsheet + PDFs into `./import/` at the repo root — the dev compose bind-mounts it to `/import` automatically.
-
-**Staging/production:**
-
-1. Pre-stage the payload on the host. Convention: `/srv/familienarchiv-staging/import/` or `/srv/familienarchiv-production/import/`.
-   ```bash
-   rsync -avh --progress ./import/ user@host:/srv/familienarchiv-staging/import/
-   ```
-2. Make sure `IMPORT_HOST_DIR=<host-path>` is set in `.env.staging` / `.env.production` (the nightly/release workflows already write this — see §3). Compose refuses to start without it.
-3. Redeploy the stack so the bind mount picks up — or, if the mount is already in place, skip to step 4.
-4. Call `POST /api/admin/trigger-import` (requires `ADMIN` permission), or click the "Import starten" button on `/admin/system`.
-5. The import runs asynchronously — poll `GET /api/admin/import-status`, watch `/admin/system`, or tail the backend logs.

-## 7. Known limitations
-
-| Limitation | Reason | Reference |
-|---|---|---|
-| **Single-node OCR service** | The two required OCR engines (Surya + Kraken) exist only in the Python ecosystem; horizontal scaling would require a job queue not currently implemented | [ADR-001](adr/001-ocr-python-microservice.md) |
-| **No multi-tenancy** | Designed as a single-family private archive; all authenticated users share the same document space | Deliberate scope decision (family-only product frame) |
-| **No multi-region** | Single PostgreSQL + MinIO instance; no replication or failover | Deliberate scope decision |
-| **Max upload size** | 50 MB per file (500 MB per request for multi-file) | Configurable in `application.yaml` (`spring.servlet.multipart`) |
-| **No automated backup** | Phase 5 of Production v1 milestone is not yet implemented | See §5 above |

-# Familienarchiv — Glossary
-
-Domain-specific and overloaded terms used in this codebase.
-Each entry: **Term** — definition (≤ 2 sentences). Where two terms are easily confused, a _Not to be confused with_ note follows.
-
-For architecture context see [`docs/architecture/c4-diagrams.md`](architecture/c4-diagrams.md).
-For domain package structure see [`docs/ARCHITECTURE.md`](ARCHITECTURE.md) _(coming: DOC-2)_.
-
----
-
-## Identity Terms
-
-**AppUser** (`AppUser`) — a real person who can log into the system (a family member or administrator). `AppUser` records carry login credentials, group memberships, and notification history.
-_Not to be confused with [Person](#person-person)_ — an AppUser is never recorded as a document sender, receiver, or historical individual.
-
-**Reader** — an `AppUser` whose effective permissions include `READ_ALL` but neither `WRITE_ALL` nor `ANNOTATE_ALL`. Readers see a dedicated dashboard (`isReader = !canWrite && !canAnnotate`) focused on browsing documents, persons, and stories rather than contribution tasks. A user who also holds `BLOG_WRITE` is still classified as a Reader and additionally sees a drafts module.
-_Not to be confused with [AppUser](#appuser-appuser)_ — Reader is a permission-derived role, not an entity.
-
-**Permission** — a discrete capability string assigned to a `UserGroup` (e.g. `READ_ALL`, `WRITE_ALL`, `ADMIN`, `ADMIN_USER`, `ADMIN_TAG`, `ADMIN_PERMISSION`). Enforced via the `@RequirePermission` AOP annotation on controller methods, checked at runtime by `PermissionAspect`; not via Spring Security's `@PreAuthorize`.
-
-**Person** (`Person`) — a historical individual in the family archive (sender, receiver of letters, person mentioned in transcriptions). NEVER has a login account and NEVER appears as an `AppUser`.
-_Not to be confused with [AppUser](#appuser-appuser)_ — `Person` is a historical record; `AppUser` is someone who can log in today.
-
-**PersonNameAlias** (`PersonNameAlias`) — an alternate or historical name form associated with a `Person` (e.g. maiden name, nickname, abbreviated form). Used to locate `Person` records during mass import via `PersonNameAliasType`.
-
-**UserGroup** (`UserGroup`) — a named permission bundle assigned to one or more `AppUser`s. A user's effective permissions are the union of all permissions across all groups they belong to.
-
----
-
-## Document-Related Terms
-
-**Annotation** (`DocumentAnnotation`) — a free-form polygon or shape drawn over a document page image to highlight a region of interest. Always scoped to a specific page of a `Document`; stored as a polygon (JSONB).
-_See also [TranscriptionBlock](#transcriptionblock-transcriptionblock)._
-
-**Comment** (`DocumentComment`, table `document_comments`) — a threaded discussion message attached to a `Document`. Always scoped to a `Document`; optionally further contextualized by a specific `DocumentAnnotation` or `TranscriptionBlock`.
-
-**Document** (`Document`) — a single archival item (letter, postcard, photograph) with a file stored in MinIO/S3 and associated metadata (sender, receivers, date, tags, transcription blocks).
-
-**DocumentVersion** (`DocumentVersion`) — an append-only snapshot of a `Document`'s metadata at a point in time. Append-only by convention; no consumer-facing create or update endpoint exists. The entity uses Lombok `@Data` (which generates setters), so immutability is enforced by application convention, not at the Java level.
-
-**Tag** (`Tag`) — a hierarchical category that can be applied to `Document`s. Tags are self-referencing via a `parent_id` foreign key, forming a tree structure.
-
-**TranscriptionBlock** (`TranscriptionBlock`) — a paragraph-level segment of a `Document`'s transcribed text, with a polygon region (stored as JSONB) identifying its position on the page. One document can have many blocks across multiple pages.
-_See also [Annotation](#annotation-documentannotation)._
-
----
-
-## Workflow Terms
-
-**DocumentStatus lifecycle** — the ordered states a `Document` moves through:
-`PLACEHOLDER → UPLOADED → TRANSCRIBED → REVIEWED → ARCHIVED`
-- `PLACEHOLDER`: created during mass import; no file attached yet.
-- `UPLOADED`: a file has been stored in MinIO/S3.
-- `TRANSCRIBED`: all transcription blocks have been marked done.
-- `REVIEWED`: a reviewer has approved the transcription.
-- `ARCHIVED`: the document is finalized and read-only.
-
-**Mass import** — an asynchronous batch process (`MassImportService`) that reads an Excel or ODS file and creates `Person`s, `Tag`s, and `PLACEHOLDER` `Document`s in one shot. Only one import can run at a time (`IMPORT_ALREADY_RUNNING` error if attempted concurrently).
-
-**Transcription queue** — the set of `Document`s and `TranscriptionBlock`s awaiting work, computed on-the-fly from `Document`/`Block` status. Three views: segmentation queue, transcription queue, ready-to-read queue. NOT a persistent entity — no `transcription_queues` table exists.
-_See also [DocumentStatus lifecycle](#documentstatus-lifecycle)._
-
----
-
-## OCR-Specific Terms
-
-**HTR** — Handwritten Text Recognition. Recognizes cursive and historical handwriting (contrasted with OCR for printed/typewritten text). The primary mode used for letters in this archive.
-
-**Kurrent** — Old German cursive handwriting style, the primary historical script appearing in letters from the 1899–1950 period covered by this archive.
-
-**OCR** — Optical Character Recognition. Recognizes printed or typewritten text. Used for typed documents; HTR is used for handwritten ones.
-
-**OcrJob** (`OcrJob`, table `ocr_jobs`) — a first-class persistent entity tracking a batch OCR run across one or more documents (`OcrJobDocument`, table `ocr_job_documents`). Distinct from the concept of "running OCR on a single document." Lifecycle: `PENDING → RUNNING → DONE / FAILED` (see `OcrJobStatus`).
-
-**SenderModel** (`SenderModel`, table `sender_models`) — a fine-tuned Kraken HTR model trained on a specific historical correspondent's handwriting. Both an OCR-service concept (the model weights) and a persistent entity linking a `Person` to the path of their trained model file.
-
-**Sütterlin** — A specific standardized style of Kurrent taught in German schools from 1915 to 1941.
-
----
-
-## Other Domain Terms
-
-**Aktivität / Aktivitäten** `[user-facing]` — the family activity feed accessible at `/aktivitaeten`. Shows recent documents, transcriptions, comments, and Geschichten as a chronological timeline.
-_See also [Chronik](#chronik-internal)._
-
-**Briefwechsel** `[user-facing]` — the bilateral conversation timeline between two `Person`s, derived from `Document` sender/receiver relationships. Accessible at `/briefwechsel`. Not a persistent entity — data is computed from existing `Document` records.
-_See also [Derived domain](#derived-domain)._
-
-**Chronik** `[internal]` — the conceptual and code-level name for the unified activity feed (per ADR-003 `003-chronik-unified-activity-feed.md`). Used in code, architecture documents, and ADRs. The user-facing label for the same concept is [Aktivität](#aktivitat--aktivitaten-user-facing).
-
-**Geschichte** (`Geschichte`) `[user-facing]` — a narrative story or article published in the archive, linking `Person`s and `Document`s. Lifecycle: `DRAFT → PUBLISHED` (see `GeschichteStatus`). DRAFT stories are hidden from users without the `BLOG_WRITE` permission.
-
-**Notification** (`Notification`) — an in-app message delivered to an `AppUser`. No email or SMS delivery exists today. Delivered via Server-Sent Events (`SseEmitterRegistry`) and persisted in the `notifications` table.
-
-**Audit log** (`AuditLog`, table `audit_log`) — an append-only event store recording domain-level activity (document edits, user actions, etc.). Append-only by application convention; a `REVOKE UPDATE, DELETE` is attempted at the DB layer (see migrations V46, V47) but is a no-op if the application role is the table owner in PostgreSQL. Do not rely on DB-enforced immutability — the constraint is application-layer only.
-
----
-
-## Architectural Terms
-
-**Cross-cutting** — code that lives in `lib/shared/` (frontend) or cross-domain packages (backend) because it has no entity of its own, no user-facing CRUD, AND is used by two or more domains OR is framework infrastructure (error handling, API client, i18n utilities).
-
-**Derived domain** — a Tier-2 frontend domain that has its own UI but no backend entities of its own. Data is computed from Tier-1 domain records. Current derived domains: `conversation` (from `Document` sender/receivers) and `activity` (from audit, notifications, document events).
-_See also [Briefwechsel](#briefwechsel-user-facing)._
-
-**Domain** — a Tier-1 bounded context with its own entities, controller, service, repository, and DTOs. Backend domains: `document`, `person`, `tag`, `user`, `geschichte`, `notification`, `ocr`, `audit`, `dashboard`. Frontend domains mirror this structure under `src/lib/`.
-
----
-
-## Infrastructure Terms
-
-**archiv-app** — the bucket-scoped MinIO service account the backend uses to read and write the `familienarchiv` bucket. Distinct from the MinIO root account (`archiv`, used only by the bootstrap container for admin operations). Defined and provisioned in [`infra/minio/bootstrap.sh`](../infra/minio/bootstrap.sh) and consumed by the backend as `S3_ACCESS_KEY` in [`docker-compose.prod.yml`](../docker-compose.prod.yml). The attached `archiv-app-policy` grants `s3:GetObject/PutObject/DeleteObject` on `familienarchiv/*` and `s3:ListBucket/GetBucketLocation` on the bucket only — not the built-in `readwrite` policy which would grant `s3:*` on all buckets.
-_See also [ADR-010 — MinIO stays self-hosted, not Hetzner OBS](./adr/010-minio-self-hosted-not-hetzner-obs.md)._
-
----
-
-## Pending Terms
-
-_Terms flagged as potentially ambiguous that have not yet been formally defined here. Add an entry above and remove it from this list when resolved._
-
-- Terms surfaced by Epic 1 audit findings (#388–#392) — review audit reports under `docs/audits/` when available and add any term flagged as ambiguous.
-- `OcrBatchService` vs `OcrAsyncRunner` — both handle async OCR orchestration; their division of responsibility should be clarified here.
-- `Stammbaum` — the genealogy tree view; relationship to `PersonRelationship` entity.

-## ADR (`adr/`)
-
-Architecture Decision Records capture major technical decisions and their rationale.
-
-| ADR                                    | Title                                | Status   |

-| `001-ocr-python-microservice.md`       | OCR as a separate Python container   | Accepted |
-| `002-polygon-jsonb-storage.md`         | Polygon coordinates in JSONB columns | Accepted |
-| `003-chronik-unified-activity-feed.md` | Unified activity feed (Chronik)      | Accepted |
-
-When making a significant architectural change (new service, data model change, technology swap), write a new ADR:
-
-- **Status** (Proposed / Accepted / Deprecated / Superseded)
-- **Context** (forces at play)
-- **Decision** (what we decided)
-- **Consequences** (trade-offs)
-- **Alternatives Considered** (table format)
-
-ADRs are sequential (`NNN-descriptive-name.md`). Do not reuse numbers.
-
-## Architecture (`architecture/`)
-
-Contains C4 model diagrams describing the system at different zoom levels:
-
-- **Context diagram** — How Familienarchiv fits into the user and system ecosystem
-- **Container diagram** — The high-level technology choices (Spring Boot, SvelteKit, PostgreSQL, MinIO, OCR service)
-- **Component diagram** — Major structural components within the backend
-
-Written in Markdown with embedded Mermaid diagrams (`c4-diagrams.md`). Gitea renders these automatically.
-
-For the human-readable architecture narrative, see [`docs/ARCHITECTURE.md`](ARCHITECTURE.md).
-
-## Infrastructure (`infrastructure/`)
-
-Operational documentation for running Familienarchiv in production and CI.

-
-## Specs (`specs/`)
-
-High-fidelity UI/UX specifications written as standalone HTML files. These are design documents describing exact layout, interactions, and responsive behavior before implementation.
-
-Each spec typically includes:
-
-- Visual mockups with CSS-in-HTML styling
-- Interaction flows and state transitions
-- Responsive breakpoint behavior
-- Accessibility requirements
-
-Before implementing a feature, check `specs/` for an existing specification.
-
-## Style Guide

-[`docs/STYLEGUIDE.md`](STYLEGUIDE.md) covers:
-
-- Code formatting and linting rules
-- Component naming conventions
-- Color palette and typography
-- Accessibility standards (WCAG 2.1 AA)

-# ADR-007: Reader-dashboard permission discriminant
-
-## Status
-
-Accepted
-
-## Context
-
-Issue #447 introduced two distinct user cohorts on the home page:
-
-- **Contributors** — transcribe, annotate, upload. The existing `MissionControlStrip`, `EnrichmentBlock`, `DashboardResumeStrip`, `DashboardFamilyPulse`, `DashboardActivityFeed`, and `DropZone` are aimed at them.
-- **Readers** — browse and consume finished content. Older, less technical, on smaller devices. The contribution-focused widgets are noise to them.
-
-`AppUser` permissions are already derived in `+layout.server.ts` and exposed via `$page.data` as `canWrite`, `canAnnotate`, and `canBlogWrite`. The home route needs a single boolean to switch its layout and its data fetch set, and that boolean has to be load-bearing — every future permission introduced has to be classified against it.
-
-## Decision
-
-```ts
-const isReader = !canWrite && !canAnnotate;
-```
-
-Computed at the start of `+page.server.ts` `load()`. When true, the loader fetches a lean reader set (stats / top-4 persons / recent docs / recent stories — and drafts when `canBlogWrite`) via `Promise.allSettled` and returns a discriminated-union shape the page distinguishes via `data.isReader`.
-
-`BLOG_WRITE` is **not** part of the discriminant. A `READ_ALL + BLOG_WRITE` user is still a reader and additionally sees the `ReaderDraftsModule`. Story writers are conceptually closer to readers than to transcribers: they consume the archive, occasionally publish narrative on top of it, and have no business with the transcription queue.
-
-A `BLOG_WRITE`-only user (no `READ_ALL`) is also classified as a reader by this formula. Because every reader API requires `READ_ALL`, all four content tiles degrade to empty via `Promise.allSettled`. They see the empty reader shell plus the drafts module — acceptable behaviour, since this permission combination is degenerate by configuration. Documented in `docs/GLOSSARY.md`.
-
-## Alternatives Considered
-
-| Alternative | Why rejected |
-|---|---|
-| New `/reader-home` route with a server-side redirect from `/` | Two routes that mostly answer the same product question (home page). Bookmarks split, breadcrumbs split, header `home` link has to know which to use. The conditional-render keeps a single canonical URL and lets the auth state drive the layout, matching how `canWrite` already gates the upload zone in the contributor branch. |
-| `AppUser.dashboardVariant` column persisted in the DB | Permissions already encode the relevant signal; a separate field has to be kept in sync with permission changes. Drift is a feature foot-gun: a user gets `WRITE_ALL` granted but their `dashboardVariant` field still says `reader` and they keep seeing the wrong UI. |
-| Middleware/handle hook redirecting based on permissions | Same logical issue as the dedicated route plus a network round-trip on every dashboard hit. The discriminant runs once inside the same `load()` that's already fetching the user. |
-| `isReader = !canWrite && !canAnnotate && !canBlogWrite` (exclude `BLOG_WRITE` from readers) | Treats blog writers as contributors. They would land on the `MissionControlStrip` they cannot meaningfully use (no `WRITE_ALL`, no `ANNOTATE_ALL`) and would have to scroll past the transcription queue to find their own drafts. The reader shell + drafts module fits their actual workflow. |

-## Consequences
-
-**Easier:**
-- Reader and contributor views share one canonical home URL — no redirect, no routing fork.
-- Adding a new content tile to the reader dashboard is a single-file change inside the `if (isReader)` branch of `load()` plus a new component import in `+page.svelte`.
-- Backend `@RequirePermission(READ_ALL)` on every reader API call remains the load-bearing security gate. `isReader` is purely a UX flag — manipulating it client-side serves a different layout to the same authenticated user with the same permissions.
-
-**Harder:**
-- Every future `Permission` value has to be explicitly classified against this formula. Adding a permission that grants contribution rights but not `WRITE_ALL`/`ANNOTATE_ALL` would silently leave its bearers on the reader dashboard. Mitigation: keep this ADR linked from `+page.server.ts` and from the `Permission` enum's Javadoc.
-- The discriminated-union return type of `load()` (`{isReader: true} | {isReader: false}`) requires every consumer to narrow on `data.isReader` before accessing branch-specific fields. The current `+page.svelte` already does this with the top-level `{#if data.isReader}`; new consumers of the home loader must follow suit.
-
-## Future Direction
-
-If a third cohort emerges (e.g. an admin home with system-health tiles), promote the discriminant to a tagged-union: `dashboard: 'reader' | 'contributor' | 'admin'`. The discriminant computation moves from `+page.server.ts` into a small helper in `lib/shared/server/`, callable from any route that needs the same classification (e.g. a future `/welcome` onboarding flow).
-
-If `BLOG_WRITE`-only access becomes a real product mode (rather than the degenerate combination it is today), revisit whether the formula should add a `canRead` precondition: `isReader = canRead && !canWrite && !canAnnotate`.

-# ADR-008: SQL-level pagination for full-text search via window-function CTE
-
-## Status
-
-Accepted
-
-## Context
-
-`DocumentRepository.findAllMatchingIdsByFts` (formerly `findRankedIdsByFts`) returns all matching document IDs for a FTS query. `DocumentService.searchDocuments` then paginates in memory on the RELEVANCE sort path.
-
-A pre-production audit against 1,520 documents measured:
-
-```
-rows_per_call: 911 / call  (query: "walter")
-```
-
-At current scale this is acceptable — 911 UUIDs ≈ 14 KB, ms-level DB time. At 100 K+ documents two failure modes emerge:
-
-1. **Memory**: a broad query returns ~60 K UUIDs ≈ 1 MB per request, multiplied by concurrent users.
-2. **Latency**: the `LATERAL` join does work proportional to match-set size; at 60 K matches the FTS step alone exceeds 100 ms per query.
-
-Tracked as finding **F-31 (High)** in the pre-production architectural review.
-
-## Decision
-
-Push pagination and rank ordering into SQL for the RELEVANCE sort path when no non-text filters are active (pure full-text search):
-
-```sql
-WITH q AS (
-  SELECT CASE WHEN websearch_to_tsquery('german', :query)::text <> ''
-              THEN to_tsquery('simple', regexp_replace(
-                       websearch_to_tsquery('german', :query)::text,
-                       '''([^'']+)''', '''\\1'':*', 'g'))
-         END AS pq
-), matches AS (
-  SELECT d.id, ts_rank(d.search_vector, q.pq) AS rank
-  FROM documents d, q
-  WHERE d.search_vector @@ q.pq
-)
-SELECT id, rank, COUNT(*) OVER () AS total
-FROM matches
-ORDER BY rank DESC, id
-OFFSET :offset LIMIT :limit
-```
-
-`COUNT(*) OVER ()` returns the full match count alongside each page row in a single round-trip — no separate count query needed.
-
-`rows_per_call` for the FTS query drops from match-set size (911) to page size (≤ 50).
-
-When non-text filters (date range, sender, receiver, tags, status) are also active, the existing path is preserved: `findAllMatchingIdsByFts` returns all ranked IDs, which are passed as an `IN` clause to the JPA Specification, and `totalElements` comes from the JPA `Page.getTotalElements()`. This keeps the count accurate across the combined filter set.
-
-## Alternatives Considered
-
-**1. Two-query approach (separate COUNT + paged SELECT)**
-Correct, but doubles round-trips. The window function achieves the same result in one query.
-
-**2. Capped result set with a user-visible warning**
-Return at most N results (e.g. 500) and show "showing top 500 of many results". Simpler, but degrades UX for broad queries and doesn't reduce latency proportionally (still scans N rows).
-
-**3. Full SQL rewrite combining FTS + JPA Specification filters**
-Possible via a native query that embeds all filter predicates. Eliminates the in-memory SENDER/RECEIVER sort paths and the two-phase approach. High complexity, tight coupling to schema details, loses type-safe JPA Specification composition. Deferred to a future refactor if scale demands it.
-
-## Consequences
-
-- **`rows_per_call` for pure-text FTS searches drops to ≤ page size** — the primary metric.
-- **SENDER and RECEIVER sort paths stay in-memory** for combined text+filter queries. For pure-text queries with SENDER/RECEIVER sort, the current approach (fetch all matched IDs, build spec, load all matched entities, sort in-memory) still runs. This is acceptable while the archive stays under ~10 K documents.
-- **RELEVANCE sort with text+filters still loads the full filtered entity set in-memory.** The filtered set is typically much smaller than the raw FTS match set, so the cost is bounded by filter selectivity, not total match count.
-- **`findAllMatchingIdsByFts` is retained** for: (a) the bulk-edit "select all" fast path (`findIdsForFilter`), (b) the document density chart (`getDensity`), and (c) the SENDER/RECEIVER in-memory sort paths.
