+### 🚀 Release Procedure
+
+This project uses version-tag-based CI/CD. Releases trigger automated Docker builds and deployments.
+
+**Release Steps:**
+
+1. Update version in `pubspec.yaml` (bump major.minor.patch, not build number)
+2. Update `CHANGELOG.md` with changes under `## [x.x.x] - YYYY-MM-DD`
+3. Commit changes: `git commit -m "chore: release vX.X.X"`
+4. Create git tag: `git tag vX.X.X`
+5. Push with tags: `git push origin master --tags`
+
+CI/CD auto-triggers when a tag starting with `v` is pushed.
+
+**What happens on release:**
+
+* Gitea CI builds Flutter web app in Docker
+* Image pushed to `git.schweitz.internal/jpmschweitzer/tatlock-ui:latest` and `:vX.X.X`
+* Watchtower detects new image and auto-updates running container
+* App available at `http://tower:8092` (and eventually `home.schweitz.net`)
+
+**Rollback:**
+
+* In Portainer, update image tag to previous version (e.g., `:v0.2.0`)
+* Or: `docker pull git.schweitz.internal/jpmschweitzer/tatlock-ui:v0.2.0`
+
 ### 🧪 Testing Requirements
+
 * **Always add tests for new code before committing.** No exceptions.
 * Tests should cover the happy path and key edge cases.
 * Run `flutter test` before committing to ensure all tests pass.

+
+* **Before modifying the widget tree**, read `docs/UI_LAYOUT.md` to understand established patterns.
+* Investigate existing implementations in the codebase before creating new components.
+* **DO NOT** reinvent wheels - check if shared components already exist in `lib/shared/components/`.
+* Look at similar features for reference patterns (e.g., how other list views, forms, or CRUD screens are built).
+* Deviating from established patterns creates inconsistency and technical debt.

+- Removed page swipe transitions - all navigation is now instant (NoTransitionPage)
+
+## [1.1.9] - 2026-01-04

+  - Enables NPM forward auth path exclusion for health endpoint
+
+## [1.1.8] - 2026-01-04

+
+## [1.1.7] - 2026-01-04
+
+### Removed
+- Removed `/callback` route from Flutter router - AuthController handles callback in main() before app starts
+- Removed `_OidcCallbackPage` widget - no visible auth UI needed
+
+## [1.1.6] - 2026-01-04
+
+### Changed
+- **Auth moved to standalone controller** - Handles OIDC completely outside Riverpod
+  - New `AuthController` runs in `main()` before `runApp()` - avoids provider lifecycle issues
+  - Handles callback, token exchange, and /auth/sync before app starts
+  - If auth not ready (redirecting), app doesn't start at all
+  - `AuthProvider` now just loads stored tokens (no async OIDC logic)
+  - Fixes "Cannot use Ref after disposed" errors from autoDispose providers
+
+## [1.1.5] - 2026-01-04
+
+### Fixed
+- Race condition in OIDC callback: AuthProvider.build() was initiating silent OIDC while the callback page was processing, causing PKCE state to be cleared. Now skips silent OIDC when on `/callback` route.
+
+## [1.1.4] - 2026-01-04
+
+### Fixed
+- Silent OIDC fallback: when `prompt=none` fails with `login_required` (no Authentik session), automatically fall back to regular OIDC flow to show login UI
+
+## [1.1.3] - 2026-01-04
+
+### Changed
+- **Web auth uses silent OIDC with JWT Bearer tokens**
+  - Uses `prompt=none` to silently obtain JWT when Authentik session exists (via NPM forward auth)
+  - Flutter sends Bearer token to core-api instead of relying on forward auth cookies
+  - Fixes cross-subdomain cookie issues between home.schweitz.net and api.schweitz.net
+  - Callback now syncs with `/auth/sync` to get user profile and roles from core-api
+  - API interceptor now adds Bearer token on web (previously skipped)
+
+## [1.1.2] - 2026-01-04
+
+### Changed
+- **Web auth simplified**: Skip Flutter OIDC on web - NPM forward auth handles it
+  - NPM authenticates at proxy level before app loads
+  - No more redundant OIDC redirect after NPM auth completes
+  - Fixes "Cannot use Ref after disposed" error from conflicting auth flows
+  - Mobile still uses Flutter OIDC flow
+
+### Added
+- Logout now redirects to Authentik to end SSO session
+  - Clears local tokens AND invalidates Authentik session
+  - Uses OIDC end_session_endpoint from discovery document
+  - Redirects back to app after Authentik logout completes
+
+## [1.1.0] - 2026-01-04
+
+### Changed
+- **Dockerfile rebuild fix**: Added `flutter clean` before build to prevent stale cached artifacts
+  - VERSION build arg added for explicit cache busting
+  - Reordered build steps: clean → pub get → build_runner → health.json → flutter build
+  - Ensures deployed app always matches the version in health.json
+
+### Fixed
+- Replaced deprecated `dart:html` with `package:web` in iframe_view_web.dart
+  - Uses `web.HTMLIFrameElement` instead of `html.IFrameElement`
+  - Fixes deprecation warnings for Flutter 3.x web builds
+
+## [1.0.12] - 2026-01-04
+
+### Changed
+- Removed login page - auth now auto-initiates from AppScaffold
+  - No more redirect to /login, just auto-start OIDC if not authenticated
+  - Shows loading screen during auth, error screen on failure with retry
+  - Seamless experience when Authentik session exists
+
+### Removed
+- Removed /login route and _LoginPage widget
+
+## [1.0.11] - 2026-01-04
+
+### Changed
+- Web auth now extracts user info directly from JWT instead of syncing with core-api
+  - Eliminates CORS preflight issues with /auth/sync endpoint
+  - Decodes JWT claims (name, email, groups) client-side
+  - Bearer token will be used for API authentication
+
+## [1.0.10] - 2026-01-04
+
+### Fixed
+- Fixed OIDC callback route being redirected to login before processing
+  - Moved callback route exception check BEFORE the auth redirect check in router
+  - This was preventing token exchange from ever happening
+- Added favicon.ico to web root for proper browser tab icon display
+
+## [1.0.9] - 2026-01-04
+
+### Fixed
+- Fixed OIDC callback Riverpod state modification error
+  - Deferred callback processing to `addPostFrameCallback` to avoid modifying state during widget build
+
+## [1.0.8] - 2026-01-04
+
+### Changed
+- Switched from hash-based URLs (`/#/login`) to path-based URLs (`/login`)
+  - Required for OIDC callback to work correctly
+  - Uses conditional import to avoid breaking mobile/desktop builds
+
+## [1.0.7] - 2026-01-04
+
+### Fixed
+- Fixed OIDC PKCE state loss across browser redirect
+  - Code verifier and state now persist in sessionStorage instead of memory
+  - Prevents "No code verifier" error after Authentik redirect
+
+## [1.0.6] - 2026-01-04
+
+### Fixed
+- Fixed version generation in CI/CD builds
+- Removed generated files (version.g.dart, health.json) from git tracking
+- These files are now regenerated from pubspec.yaml during Docker build
+
+## [1.0.5] - 2026-01-04
+
+### Changed
+- **Web authentication now uses OIDC** instead of NPM forward auth
+  - Added `OidcServiceWeb` for browser redirect-based Authorization Code flow with PKCE
+  - Added `/callback` route to handle Authentik redirect after login
+  - Login page now shows "Sign in with Authentik" button for both web and mobile
+  - Tokens stored in SharedPreferences and synced with core-api via `/auth/sync`
+- Added web utility functions (`web_utils.dart`) with conditional imports for non-web platforms
+- Added `crypto` and `web` packages for PKCE SHA-256 and browser API access
+
+### Fixed
+- Removed cross-origin cookie dependency that caused authentication failures on web
+
+## [1.0.4] - 2026-01-03
+
+### Added
+- `health.json` generated at build time with app version info
+- `health.html` now displays version, title, and status from health.json

+
+### Fixed
+- Fixed auth endpoint path: `/auth/me` → `/auth/users/me`
+
+## [1.0.2] - 2026-01-03
+
+### Fixed
+- Production Docker build now uses correct API URLs
+  - Added `--dart-define` flags for `CORE_API_URL` and `TATLOCK_API_URL`
+  - This enables `requiresAuth=true` so authentication is actually triggered
+- Updated AGENTS.md with clear service port reference table
+
+## [1.0.1] - 2026-01-03
+
+### Fixed
+- Web authentication now works correctly with NPM forward auth
+  - Dio client sends cookies with requests via `withCredentials: true`
+  - Added platform-specific adapters (native vs web) for proper cookie handling
+
+## [1.0.0] - 2026-01-03
+
+### Added
+- **Authentication System** - Dual-flow auth supporting web (NPM forward auth) and mobile (OIDC)
+  - `AuthState` model with roles, permissions, and user preferences
+  - `AuthProvider` with automatic web session detection via `/auth/me`
+  - Permission system with Domain/Action enums and hierarchical access levels

+- Login page with Authentik OAuth redirect
+- Mobile auth platform configuration (iOS URL schemes, Android AppAuth)
+- Comprehensive auth test suite (60 unit tests)
+
+### Changed
+- API interceptor skips Bearer tokens on web (uses cookies via NPM forward auth)
+- Router integrates auth state for protected route access
+- **First stable release** - Core functionality complete for home lab dashboard
+
+## [0.3.3] - 2026-01-03
+
+### Added

+# Auth Flow Refactor: Invisible Token Exchange
+
+> Research note for future implementation
+
+## Problem
+
+The `/callback?code=...` URL is visible in the browser during token refresh. This happens every time tokens need refreshing, not just on initial login. The current implementation appears to re-run the full OIDC redirect flow (`prompt=none`) instead of using the refresh_token.
+
+## Current Behavior
+
+```
+Token expires → Redirect to Authentik (prompt=none) →
+Redirect to /callback?code=xxx → Exchange code → Continue
+```
+
+User sees URL flicker to `/callback` repeatedly.
+
+## Desired Behavior
+
+```
+Token expires → Show overlay (lock/lightning icon) →
+XHR refresh request → Hide overlay → Continue
+```
+
+No URL changes. No redirects. Just a brief visual indicator.
+
+## Key Insight
+
+**Only the initial authorization MUST redirect** (user needs to see Authentik login UI).
+
+Everything else can be XHR:
+
+| Operation | Current | Should Be |
+|-----------|---------|-----------|
+| Initial login | Redirect | Redirect (unavoidable) |
+| Token exchange (code → tokens) | Redirect to /callback | XHR POST |
+| Token refresh | Full OIDC with prompt=none | XHR POST with refresh_token |
+| Session expired | Redirect | Redirect (unavoidable) |
+
+## Token Refresh via XHR
+
+```dart
+final response = await dio.post(
+  'https://authentik.schweitz.net/application/o/token/',
+  data: {
+    'grant_type': 'refresh_token',
+    'refresh_token': storedRefreshToken,
+    'client_id': clientId,
+  },
+  options: Options(
+    contentType: Headers.formUrlEncodedContentType,
+  ),
+);
+// Returns new access_token, refresh_token, expires_in
+```
+
+## Potential Blocker: CORS
+
+Authentik's token endpoint may block browser XHR. Solutions:
+
+1. **Configure Authentik CORS** - Allow `home.schweitz.net` origin
+2. **Proxy through core-api** (recommended)
+   - Flutter → `POST /auth/refresh` → core-api → Authentik
+   - Keeps client_secret server-side
+   - No CORS issues
+
+## Implementation Steps
+
+1. [ ] Verify Authentik is issuing refresh_tokens (check token response)
+2. [ ] Check if refresh_token is being stored (SharedPreferences)
+3. [ ] Test XHR to token endpoint (check CORS)
+4. [ ] If CORS blocked, add `/auth/refresh` endpoint to core-api
+5. [ ] Refactor `AuthProvider` to use XHR refresh instead of full OIDC flow
+6. [ ] Add refresh overlay UI (lock icon + brief animation)
+7. [ ] Remove `prompt=none` redirect logic for refresh cases
+

 ```

+## Data Model Patterns
+
+Models handle conversion between API JSON and domain entities. The pattern depends on whether the feature is **read-only** or **CRUD**.
+
+### Read-Only Models
+
+For data fetched from external systems (Docker, NPM, Portainer) where Flutter doesn't create/update records:
+
+```dart
+@freezed
+sealed class ContainerModel with _$ContainerModel {
+  const factory ContainerModel({
+    required String id,
+    required String name,
+    required String status,
+  }) = _ContainerModel;
+
+  const ContainerModel._();
+
+  factory ContainerModel.fromJson(Map<String, dynamic> json) =>
+      _$ContainerModelFromJson(json);
+
+  /// Converts API response to domain entity.
+  Container toEntity() => Container(
+    id: id,
+    name: name,
+    status: ContainerStatus.values.byName(status),
+  );
+}
+```
+
+**Only `toEntity()` is needed** - no `fromEntity()` or `toJson()` required.
+
+### CRUD Models (Bidirectional)
+
+For data that Flutter creates, updates, and deletes:
+
+```dart
+@freezed
+sealed class QuickLinkModel with _$QuickLinkModel {
+  const factory QuickLinkModel({
+    @Default(0) int id,
+    required String title,
+    required String url,
+    String? icon,
+    String? category,
+    @Default(0) int position,
+    @JsonKey(name: 'is_visible') @Default(true) bool isVisible,
+  }) = _QuickLinkModel;
+
+  const QuickLinkModel._();
+
+  factory QuickLinkModel.fromJson(Map<String, dynamic> json) =>
+      _$QuickLinkModelFromJson(json);
+
+  /// Converts API response to domain entity.
+  QuickLink toEntity() => QuickLink(
+    id: id.toString(),
+    name: title,
+    url: url,
+    iconName: icon ?? 'link',
+    category: category,
+    sortOrder: position,
+    isActive: isVisible,
+  );
+
+  /// Creates model from domain entity for API requests.
+  factory QuickLinkModel.fromEntity(QuickLink entity) => QuickLinkModel(
+    id: int.tryParse(entity.id) ?? 0,
+    title: entity.name,
+    url: entity.url,
+    icon: entity.iconName,
+    category: entity.category,
+    position: entity.sortOrder,
+    isVisible: entity.isActive,
+  );
+}
+```
+
+**Critical rules for CRUD models:**
+
+1. **Always use generated `toJson()`** - Never write custom JSON methods that selectively include fields. The generated `toJson()` from freezed/json_serializable always includes ALL fields, which is the correct behavior.
+
+2. **Never create custom `toCreateJson()` or similar** - This leads to bugs where fields are silently dropped.
+
+3. **Use `fromEntity()` factory** - Maps domain entity fields to API field names.
+
+### Form Update Pattern
+
+When updating existing entities in forms, **always use `copyWith()`** to preserve existing data:
+
+```dart
+// ✅ Correct - preserves all existing fields
+final updatedLink = existingLink.copyWith(
+  name: _nameController.text.trim(),
+  url: _urlController.text.trim(),
+  category: category.isEmpty ? null : category,
+);
+await actions.update(updatedLink);
+
+// ❌ Wrong - loses existing data not in form
+final newLink = QuickLink(
+  id: existingLink.id,
+  name: _nameController.text.trim(),
+  url: _urlController.text.trim(),
+  // Missing: sortOrder, other fields...
+);
+```
+
+### Datasource Usage
+
+```dart
+// Create - convert entity to model, use toJson()
+Future<QuickLink> createQuickLink(QuickLink link) async {
+  final model = QuickLinkModel.fromEntity(link);
+  final response = await _dio.post<Map<String, dynamic>>(
+    _basePath,
+    data: model.toJson(), // Always use generated toJson()
+  );
+  return QuickLinkModel.fromJson(response.data!).toEntity();
+}
+
+// Update - same pattern
+Future<QuickLink> updateQuickLink(QuickLink link) async {
+  final model = QuickLinkModel.fromEntity(link);
+  final response = await _dio.put<Map<String, dynamic>>(
+    '$_basePath/${link.id}',
+    data: model.toJson(), // Always use generated toJson()
+  );

+### Persistent Providers
+
+By default, `@riverpod` generates providers with `isAutoDispose: true`, meaning they dispose when no longer watched. This causes issues for:
+
+- **API clients** with interceptors that store a `Ref`
+- **App-level state** like theme, auth, config
+- **Providers with listeners** to other providers
+
+Use `@persistentRiverpod` from `core/providers/annotations.dart` for these cases:

+## Semantic Identifiers for Automation
+
+All interactive widgets should have semantic identifiers for UI automation. This enables reliable testing with Puppeteer, Appium, and other automation tools.
+
+### Quick Reference

+  identifier: DataGridSemantics.row(item.id),
+  label: 'Select ${item.name}',
+  child: MyRowWidget(item: item),
+)
+```
+
+### Key Points
+
+1. **Central ID Registry** - All IDs defined in `lib/core/semantics/semantic_ids.dart`
+2. **Naming Convention** - `{area}_{component}_{identifier}` (e.g., `dataGrid_row_abc123`)
+3. **Web Enabled** - Semantics tree exposed via `SemanticsBinding.instance.ensureSemantics()` in `main.dart`
+
+For complete documentation on semantic patterns, automation queries, and best practices, see **[TESTING.md](./TESTING.md)**.
+
+## Room Registry Pattern
+
+The application uses a **decentralized room registry** pattern for navigation. Each feature/room registers itself with the central registry, providing:
+
+- **Decoupled navigation** - Rooms define their own routes, icons, and metadata
+- **Permission-based filtering** - Rooms can specify required permissions
+- **Dynamic UI** - Settings dropdowns and tab bars build from registry
+- **Single source of truth** - All room metadata in one place per room
+
+### Architecture
+
+```
+lib/routing/room_registry.dart          # Central registry class
+lib/features/{room}/router.dart         # Per-room registration
+```
+
+### Room Definition
+
+Each room's `router.dart` exports a `RoomDefinition` and register function:
+
+```dart
+// lib/features/control_room/router.dart
+import 'package:tatlock_ui/routing/room_registry.dart';
+
+/// Room definition with all metadata.
+final controlRoomRoom = RoomDefinition(
+  id: 'control-room',              // Preference value, URL segment
+  label: 'Control Room',           // Display name
+  icon: Icons.dns_outlined,        // Unselected icon
+  selectedIcon: Icons.dns,         // Selected icon
+  defaultRoute: '/control-room/containers',  // Landing route
+  routes: controlRoomRoutes,       // Function returning List<RouteBase>
+  requiredPermissions: [],         // Empty = accessible to all
+);
+
+/// Register with the central registry.
+void registerControlRoom() {
+  roomRegistry.register(controlRoomRoom);
+}
+
+/// Routes for go_router.
+List<RouteBase> controlRoomRoutes() {
+  return [
+    GoRoute(path: '/control-room', ...),
+    // Sub-routes...
+  ];
+}
+```
+
+### Registration Order
+
+Rooms are registered in `app_router.dart` in display order:
+
+```dart
+void _initializeRoomRegistry() {
+  if (roomRegistry.all.isNotEmpty) return; // Skip if initialized
+
+  // Registration order = tab order
+  registerFrontHall();
+  registerControlRoom();
+  registerSecurity();
+  registerParlor();
+  registerMediaRoom();
+}
+```
+
+### Using the Registry
+
+**Navigation tabs** (`top_header_bar.dart`):
+```dart
+List<RoomDefinition> get _rooms => roomRegistry.all;
+
+// Build tab for each room
+for (final room in _rooms) {
+  IconButton(
+    icon: Icon(isSelected ? room.selectedIcon : room.icon),
+    onPressed: () => onRoomSelected(index),
+  );
+}
+```
+
+**Settings dropdown**:
+```dart
+DropdownButton<String>(
+  items: roomRegistry.all
+      .map((room) => DropdownMenuItem(
+            value: room.id,
+            child: Text(room.label),
+          ))
+      .toList(),
+);
+```
+
+**Router** - All routes from registry:
+```dart
+ShellRoute(
+  routes: [
+    ...roomRegistry.allRoutes(),
+    // Plus non-room routes like /settings
+  ],
+);
+```
+
+**Route matching**:
+```dart
+int _selectedIndex(BuildContext context) {
+  final location = GoRouterState.of(context).matchedLocation;
+  return roomRegistry.indexOfRoute(location);
+}
+```
+
+### Permission Filtering
+
+Rooms can specify required permissions:
+
+```dart
+final adminRoom = RoomDefinition(
+  id: 'admin',
+  requiredPermissions: ['admin:access'],
+  // ...
+);
+
+// Filter by user permissions
+final accessibleRooms = roomRegistry.accessibleTo(userPermissions);
+```
+
+### Adding a New Room
+
+1. Create feature folder: `lib/features/{room_name}/`
+2. Create `router.dart` with `RoomDefinition` and register function
+3. Create placeholder page in `presentation/pages/{room_name}_page.dart`
+4. Add `register{RoomName}()` call to `_initializeRoomRegistry()` in `app_router.dart`
+5. Import the router in `app_router.dart`
+

+# Testing & Automation Guide
+
+This document covers automated testing patterns for Tatlock UI, focusing on semantic identifiers that enable reliable UI automation.
+
+## Overview
+
+Tatlock UI uses Flutter's **Semantics tree** to expose stable identifiers for automated testing. These identifiers are accessible to:
+
+- **Puppeteer** (via Chrome DevTools accessibility API)
+- **Appium** (via accessibility labels)
+- **WebDriver** (via ARIA attributes)
+- **Flutter integration tests**
+
+The semantics system is enabled on web in `main.dart`:
+
+```dart
+if (kIsWeb) {
+  SemanticsBinding.instance.ensureSemantics();
+}
+```
+
+## Semantic Identifiers
+
+All semantic IDs are centralized in `lib/core/semantics/semantic_ids.dart`. This provides:
+
+1. **Stable selectors** - IDs don't change with UI refactoring
+2. **Type safety** - Compile-time verification of ID usage
+3. **Discoverability** - Single source of truth for automation targets
+
+### Available ID Classes
+
+| Class | Purpose | Example IDs |
+|-------|---------|-------------|
+| `ProfileSemantics` | User profile dropdown | `profile_button`, `profile_menu_settings` |
+| `RoomTabSemantics` | Main navigation tabs | `roomTab_frontHall`, `roomTab_controlRoom` |
+| `NavSemantics` | Side navigation panel | `nav_panel`, `nav_item_{id}` |
+| `DataGridSemantics` | Data tables | `dataGrid_row_{id}`, `dataGrid_search` |
+| `DialogSemantics` | Modal dialogs | `dialog_confirm`, `dialog_cancel` |
+| `SettingsSemantics` | Settings page | `settings_theme`, `settings_defaultRoom` |
+| `StateSemantics` | Loading/error states | `state_auth_loading`, `snackbar_{type}` |
+
+### ID Naming Convention
+
+```
+{area}_{component}_{identifier}
+```
+
+- **area**: Feature or section (e.g., `profile`, `nav`, `dataGrid`)
+- **component**: Widget type (e.g., `menu`, `button`, `row`)
+- **identifier**: Specific item (e.g., `light`, `settings`, `selectAll`)
+
+Examples:
+- `profile_menu_theme_dark` - Dark theme option in profile menu
+- `dataGrid_row_abc123` - Row with ID "abc123" in data grid
+- `nav_item_containers` - Containers nav item
+
+## Adding Semantics to Widgets
+
+### Method 1: Direct Semantics Widget
+
+Use Flutter's `Semantics` widget with the `identifier` property:
+
+```dart
+import 'package:tatlock_ui/core/semantics/semantic_ids.dart';
+
+Semantics(
+  identifier: ProfileSemantics.button,
+  label: 'Open profile menu',
+  button: true,
+  child: IconButton(
+    icon: Icon(Icons.person),
+    onPressed: () => ...,
+  ),
+)
+```
+
+### Method 2: SemanticWidget Wrapper
+
+Use the convenience wrapper from `lib/core/semantics/semantic_widget.dart`:
+
+```dart
+import 'package:tatlock_ui/core/semantics/semantic_ids.dart';
+import 'package:tatlock_ui/core/semantics/semantic_widget.dart';
+
+SemanticWidget(
+  id: DataGridSemantics.search,
+  label: 'Search data grid',
+  textField: true,
+  child: TextField(
+    decoration: InputDecoration(hintText: 'Search...'),
+  ),
+)
+```
+
+### Method 3: Extension Method
+
+Use the `withSemantics` extension for inline wrapping:
+
+```dart
+TextField(
+  decoration: InputDecoration(hintText: 'Search...'),
+).withSemantics(
+  id: DataGridSemantics.search,
+  label: 'Search data grid',
+)
+```
+
+### Dynamic IDs
+
+For lists and grids, use the generator methods:
+
+```dart
+// Row in a data grid
+Semantics(
+  identifier: DataGridSemantics.row(item.id),  // "dataGrid_row_abc123"
+  child: DataGridRow(item: item),
+)
+
+// Navigation item
+Semantics(
+  identifier: NavSemantics.item(route.id),  // "nav_item_containers"
+  child: NavItem(route: route),
+)
+
+// Bulk action button
+Semantics(
+  identifier: DataGridSemantics.bulkAction('delete'),  // "dataGrid_bulk_delete"
+  child: IconButton(icon: Icon(Icons.delete), ...),
+)
+```
+
+## Querying from Puppeteer
+
+Puppeteer can query semantic identifiers via Chrome's accessibility tree:
+
+```javascript
+// Connect to Chrome with DevTools protocol
+const browser = await puppeteer.connect({
+  browserURL: 'http://localhost:9222'
+});
+const page = await browser.newPage();
+
+// Get accessibility snapshot
+const snapshot = await page.accessibility.snapshot({ interestingOnly: false });
+
+// Find element by semantic identifier
+function findBySemanticId(node, id) {
+  if (node.name === id || node.description === id) {
+    return node;
+  }
+  for (const child of node.children || []) {
+    const found = findBySemanticId(child, id);
+    if (found) return found;
+  }
+  return null;
+}
+
+// Example: Find profile button
+const profileButton = findBySemanticId(snapshot, 'profile_button');
+
+// Example: Find a specific data grid row
+const row = findBySemanticId(snapshot, 'dataGrid_row_abc123');
+```
+
+### Using Chrome DevTools MCP
+
+With the Chrome DevTools MCP server, you can query semantics directly:
+
+```javascript
+// Take a snapshot (returns accessibility tree)
+const snapshot = await mcp__chrome_devtools__take_snapshot();
+
+// Click by semantic ID (uid in snapshot)
+await mcp__chrome_devtools__click({ uid: 'profile_button' });
+
+// Fill input by semantic ID
+await mcp__chrome_devtools__fill({
+  uid: 'dataGrid_search',
+  value: 'my search query'
+});
+```
+
+## Best Practices
+
+### 1. Add Semantics to Interactive Elements
+
+Every clickable, tappable, or input element should have a semantic identifier:
+
+```dart
+// Buttons
+Semantics(
+  identifier: 'myFeature_submit',
+  button: true,
+  label: 'Submit form',
+  child: ElevatedButton(...),
+)
+
+// Text fields
+Semantics(
+  identifier: 'myFeature_email',
+  textField: true,
+  label: 'Email address',
+  child: TextField(...),
+)
+
+// Checkboxes
+Semantics(
+  identifier: 'myFeature_rememberMe',
+  checked: isChecked,
+  label: 'Remember me',
+  child: Checkbox(...),
+)
+```
+
+### 2. Use Meaningful Labels
+
+Labels help both accessibility tools and test debugging:
+
+```dart
+// Good - descriptive label
+Semantics(
+  identifier: DataGridSemantics.rowAction(item.id, 'delete'),
+  label: 'Delete ${item.name}',
+  button: true,
+  child: ...,
+)
+
+// Bad - no context
+Semantics(
+  identifier: 'btn1',
+  child: ...,
+)
+```
+
+### 3. Register New IDs Centrally
+
+Always add new semantic IDs to `semantic_ids.dart`:
+
+```dart
+/// My new feature IDs.
+abstract class MyFeatureSemantics {
+  static const submitButton = 'myFeature_submit';
+  static const cancelButton = 'myFeature_cancel';
+  static const nameField = 'myFeature_name';
+
+  /// Generate ID for a list item.
+  static String item(String id) => 'myFeature_item_$id';
+}
+```
+
+### 4. Test ID Stability
+
+Semantic IDs should remain stable across releases. When refactoring:
+
+- Keep existing IDs unchanged
+- Add deprecation comments if IDs must change
+- Update automation tests when IDs change
+
+### 5. Exclude Decorative Elements
+
+Don't add semantic IDs to purely decorative elements:
+
+```dart
+// Decorative icon - no semantics needed
+Icon(Icons.star, color: Colors.yellow)
+
+// Interactive icon - needs semantics
+Semantics(
+  identifier: 'rating_star_3',
+  button: true,
+  label: 'Rate 3 stars',
+  child: IconButton(
+    icon: Icon(Icons.star),
+    onPressed: () => rate(3),
+  ),
+)
+```
+
+## DataGrid Semantic Patterns
+
+The DataGrid component has comprehensive semantic coverage:
+
+```
+dataGrid                     - The grid container
+dataGrid_search              - Search input field
+dataGrid_search_clear        - Clear search button
+dataGrid_selectAll           - Select all checkbox
+dataGrid_header_{columnId}   - Column header (sortable)
+dataGrid_row_{itemId}        - Row container
+dataGrid_row_{itemId}_checkbox    - Row selection checkbox
+dataGrid_row_{itemId}_actions     - Row actions menu trigger
+dataGrid_row_{itemId}_action_{actionId}  - Specific row action
+dataGrid_bulk_{actionId}     - Bulk action button
+dataGrid_bulk_clear          - Clear selection button
+dataGrid_loading             - Loading indicator
+dataGrid_empty               - Empty state message
+dataGrid_error               - Error state message
+dataGrid_refresh             - Refresh button
+```
+
+### Example: Automating DataGrid Selection
+
+```javascript
+// Select all rows
+await click('dataGrid_selectAll');
+
+// Select specific row
+await click('dataGrid_row_abc123_checkbox');
+
+// Perform bulk delete
+await click('dataGrid_bulk_delete');
+
+// Confirm in dialog
+await click('dialog_confirm');
+```
+
+## Debugging Semantics
+
+### Flutter DevTools
+
+1. Open Flutter DevTools
+2. Go to "Inspector" tab
+3. Enable "Semantics" overlay
+4. Click widgets to see their semantic properties
+
+### Chrome DevTools
+
+1. Open DevTools (F12)
+2. Go to "Accessibility" tab
+3. Inspect the accessibility tree
+4. Search for semantic identifiers
+
+### Programmatic Inspection
+
+```dart
+// In a test, dump the semantics tree
+debugDumpSemanticsTree();
+
+// Check if semantics are enabled
+print('Semantics enabled: ${SemanticsBinding.instance.semanticsEnabled}');
+```
+
+## Integration with URL Routing
+
+For deep-linkable test scenarios, semantic IDs work with URL query parameters:
+
+```
+/control-room/containers?selected=abc123
+```
+
+Automation can:
+1. Navigate to URL with query params
+2. Verify selection state via `dataGrid_row_abc123_checkbox` (checked: true)
+3. Interact with selected rows via semantic IDs
+
+See [URL Routing](#url-routing) section for query parameter patterns.
+
+## Checklist for New Features
+
+When adding a new feature, ensure semantic coverage:
+
+- [ ] Add semantic ID class to `semantic_ids.dart`
+- [ ] Wrap all buttons with `Semantics` + `identifier`
+- [ ] Wrap all inputs with `Semantics` + `identifier`
+- [ ] Wrap list/grid items with dynamic IDs
+- [ ] Add labels for accessibility
+- [ ] Test that IDs appear in accessibility snapshot
+- [ ] Document IDs in this file if they establish new patterns

-### Component Roles
+---
+
+## Panel Taxonomy
+
+All panels share common styling patterns but serve different purposes.
+
+### Panel Types
+
+| Panel | Position | Purpose | Width | Content Alignment |
+|-------|----------|---------|-------|-------------------|
+| **Header Bar** | Top | Room nav, profile | 56px height | Logo in bulge, rest at bottom |
+| **Nav Panel** | Left | Room-level section nav | 280px fixed | Header docked to bottom |
+| **Filter Panel** | Left (inside content) | Data filtering/search | 280px fixed | Header docked to bottom |
+| **Detail Panel** | Right (inside content) | Selected item details | 320-400px | Standard header |
+| **Chat Dock** | Right | AI assistant | 280px-33vw | Standard header |
+
+### Panel Header Behavior
+
+All left-side panels (Nav Panel, Filter Panel) dock their header content to the **bottom** of the header area. This accommodates the logo bulge that overlays into their space.
+
+```
+┌─────────────────────────┐
+│                         │  ← Logo bulge overlays this space
+│         (empty)         │
+│                         │
+│  [Icon] Title   [Action]│  ← Content docked to bottom (8px margin)
+├─────────────────────────┤
+│  Panel content...       │
+```
+
+Right-side panels (Detail Panel, Chat Dock) use standard vertically-centered headers since the logo bulge doesn't reach them.
+
+### Nav Panel Sections
+
+Nav items can be organized into **sections**. Section headers are **conditionally visible** - they only appear when multiple sections exist.
+
+#### Single Section (headers hidden)
+
+When all items belong to one section, no headers are shown:
+
+```
+┌─────────────────────────┐
+│  [≡] Sections     [···] │  ← Panel header
+├─────────────────────────┤
+│  ▸ Containers           │
+│    Networks             │
+│    Volumes              │
+│    Images               │
+│                         │
+└─────────────────────────┘
+```
+
+#### Multiple Sections (headers visible)
+
+When items span multiple sections, section headers appear:
+
+```
+┌─────────────────────────┐
+│  [≡] Sections     [···] │  ← Panel header
+├─────────────────────────┤
+│ ▌Portainer              │  ← Section header (subtle bg, left accent)
+│  ▸ Containers           │
+│    Networks             │
+│    Volumes              │
+│    Images               │
+│                         │
+│ ▌NPM                    │  ← Section header
+│    Proxy Hosts          │
+│    Redirections         │
+│    Streams              │
+│                         │
+│ ▌Authentik              │  ← Section header
+│    Users                │
+│    Groups               │
+│    Applications         │
+│                         │
+└─────────────────────────┘
+```
+
+#### Section Header Styling
+
+```
+┌─────────────────────────┐
+│▌SECTION NAME            │  ← Left accent bar (2px, primary color)
+└─────────────────────────┘   ← Background: surfaceContainerHigh
+                              ← Text: labelSmall, onSurfaceVariant
+                              ← Padding: 8px horizontal, 6px vertical
+                              ← All caps, letter-spacing: 0.5
+```
+
+#### Data Model
+
+```dart
+/// NavItem model (in nav_panel.dart)
+class NavItem {
+  final String id;
+  final String label;
+  final IconData icon;
+  final String? section;  // null = ungrouped
+}
+
+// Section headers auto-generate from unique section values
+// Visibility: items.map((i) => i.section).toSet().length > 1
+```
+
+#### Route Configuration Driven
+
+Sections are defined in the feature's route configuration, not the widget:
+
+```dart
+/// In lib/features/control_room/router.dart
+
+enum ControlRoomNav {
+  // Portainer section
+  containers('containers', 'Containers', Icons.dns, 'Portainer'),
+  networks('networks', 'Networks', Icons.hub, 'Portainer'),
+  volumes('volumes', 'Volumes', Icons.storage, 'Portainer'),
+  images('images', 'Images', Icons.photo_library, 'Portainer'),
+  // NPM section (future)
+  proxyHosts('proxy-hosts', 'Proxy Hosts', Icons.public, 'NPM'),
+  redirections('redirections', 'Redirections', Icons.alt_route, 'NPM'),
+  // Authentik section (future)
+  users('users', 'Users', Icons.people, 'Authentik'),
+  groups('groups', 'Groups', Icons.group_work, 'Authentik');
+
+  const ControlRoomNav(this.id, this.label, this.icon, this.section);
+
+  final String id;
+  final String label;
+  final IconData icon;
+  final String section;
+
+  NavItem toNavItem() => NavItem(
+        id: id,
+        label: label,
+        icon: icon,
+        section: section,
+      );
+}
+```
+
+The NavPanel widget receives items and auto-generates section headers based on unique section values in the list. No section logic lives in the widget - it just renders what the route config provides.
+

 ## Flutter Implementation Notes

+### Panel Widget Library
+
+All panels are built from shared components in `lib/shared/layouts/widgets/`:
+
+| Widget | File | Purpose |
+|--------|------|---------|
+| `PanelContainer` | `panel_container.dart` | Base container for all panels |
+| `PanelHeader` | `panel_header.dart` | Configurable header (bottom-docked or centered) |
+| `NavPanel` | `nav_panel.dart` | Left-side room navigation |
+| `FilterPanel` | `filter_panel.dart` | Left-side data filtering |
+| `DetailPanel` | `detail_panel.dart` | Right-side item details |
+| `ChatDock` | `chat_dock.dart` | Right-side AI assistant |
+
+### PanelHeader Configuration
+
+```dart
+/// Panel header with configurable content alignment.
+class PanelHeader extends StatelessWidget {
+  const PanelHeader({
+    required this.title,
+    required this.icon,
+    this.actions,
+    this.dockToBottom = false, // true for left-side panels
+  });
+}
+```
+
+**Left-side panels** (Nav, Filter) use `dockToBottom: true` to accommodate the logo bulge:
+- Header height: 56px (matches app header)
+- Content aligned to bottom with 8px margin
+- Empty space at top allows logo bulge overlay
+
+**Right-side panels** (Detail, Chat) use `dockToBottom: false`:
+- Standard vertically-centered content
+- No accommodation needed for logo bulge
