fix(permissions): narrow rm -rf deny globs to their exact forms

The trailing wildcard on the three rm -rf deny entries spanned path
separators, so Bash(rm -rf /*) matched every absolute path on the
machine rather than the filesystem root, and the ~ and $HOME entries
had the same shape. Narrowed to the exact literal forms.

These rules match literal command text, so they still stop a typo on
rm -rf /, rm -rf ~ or rm -rf $HOME exactly, but they no longer stop a
recursive delete aimed at any other path. That reduced cover is
deliberate, not an oversight.

It is the per-clone local overrides file — the documented home for personal settings and for credentials — and it does not belong in version control at all.
+
+STATE, verified 2026-08-11 rather than assumed:
+  - the file is tracked, with 2 commits touching it (both 2025-12-31)
+  - `.gitignore` already lists it at line 137, and line 130 carries the exact `git rm --cached` command in a comment
+  - gitignore does not apply to files git already tracks, which is why the rule has been inert since it was added
+  - this is the ONLY repo in the workspace where the file is tracked; desklock, library-desk and tatlock all ignore it correctly
+
+NO CREDENTIALS WERE EVER COMMITTED. Both committed versions contain a `permissions` section and nothing else — zero env keys, checked at each commit rather than only at HEAD. This is a loaded trap, not a leak: the next person who adds an env key to this file commits a secret, and nothing will stop them because the ignore rule cannot fire on a tracked path.
+
+Worth recording because it has already cost time once: a survey agent previously reported credentials committed across nine repos. Traced to source, it was this one file holding a four-entry permission list and no secrets. The finding was wrong and the file is still tracked, so the same false alarm is available to the next person who greps for it.
+
+THE FOUR RULES IN IT ARE THE ONLY REASON TO PAUSE. They allow browser-automation MCP tools:
+  mcp__chrome-devtools__take_screenshot, take_snapshot, navigate_page
+  mcp__puppeteer__puppeteer_evaluate
+
+Untracking removes them from anyone who clones. Two ways to go, and this wants deciding rather than defaulting:
+  - they are genuinely personal (one person''s browser tooling) — untrack and let each clone re-grant
+  - they are useful to anyone working on this UI — move them into `.claude/settings.json`, which is committed by design and already carries 16 allow and 43 deny rules
+
+The second reading looks likelier for a front-end repo where visual verification is routine, but it is a judgement about how people work here, not something the file can answer.
+
+FIX: `git rm --cached .claude/settings.local.json` and commit. The file stays on disk, so nobody loses their local settings; it simply stops being shared.

-# LLM Agent Instructions
-
-This document contains instructions and documentation references for AI assistants working with this codebase.
-
-> **📖 Important**: Before working on this project, read [PHILOSOPHY.md](PHILOSOPHY.md) to understand the system vision, architectural patterns, and design goals. All development should work towards realizing those patterns.
-# AGENTS.md
-
-> **Start every session by reading this file.**
-> This file outlines the operational protocols, coding standards, and architectural decisions for this Flutter project.
-
-## 1. Agent Operational Protocols
-
-### 🧠 Work Patterns (Plan-Act-Reflect)
-* **Plan:** Before writing code, briefly outline your plan. Identify which files you will touch and what the side effects might be.
-* **Act:** Execute the changes in small, atomic steps.
-* **Reflect:** After coding, verify your work. Did you break existing tests? Did you add new tests?
-
-### 🌐 Internal Service Access
-* **git.schweitz.net**: Access via `http://localhost:3002` (direct Gitea) to bypass Authentik SSO
-  * Example: `curl http://localhost:3002/jpmschweitzer/library-desk/raw/branch/main/README.md`
-  * Public repos are readable without authentication
-  * Related repos: , `core-api`, `tatlock`, `library-desk`, `scheduler`, `portainer-core`
-
-### 🐳 Deployment & Infrastructure
-
-**⚠️ IMPORTANT: Service Port Reference**
-| Service | LAN Port | External URL | Notes |
-|---------|----------|--------------|-------|
-| **Core API** | 8083 | `api.schweitz.net` | FastAPI backend for this UI |
-| **Tatlock API** | 8000 | `tatlock.schweitz.net` | Legacy Python API (Ollama proxy) |
-| **Tatlock UI** | 9999 | `home.schweitz.net` | This Flutter app |
-
-* **Full stack documentation**: Available in the `portainer-core` repo
-  * Access: `curl http://192.168.86.149:3002/jpmschweitzer/portainer-core/raw/branch/main/CONTAINERS.md`
-  * Contains: All service ports, URLs, Redis DB allocations, external domains
-* **Health checks**:
-  * Core API: `curl http://192.168.86.149:8083/health`
-  * Tatlock API: `curl http://192.168.86.149:8000/health`
-
-### 🛡️ Git Discipline
-* **Commit Messages:** Use the [Conventional Commits](https://www.conventionalcommits.org/) format.
-    * `feat: add user login endpoint`
-    * `fix: resolve database connection timeout`
-    * `refactor: split monolith dependency file`
-* **Atomic Commits:** Keep commits small. One logical change = one commit.
-* **Version Tagging:** Every version increment (major.minor.patch, not build count) must have a corresponding git tag.
-    * Format: `v{major}.{minor}.{patch}` (e.g., `v0.3.0`)
-    * Tag after updating `pubspec.yaml` version and CHANGELOG
-    * Push tags with `git push --tags`
-
-### 🚀 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`
-6. Create release in Gitea UI (git.schweitz.net → Releases → New Release)
-   * Select the tag
-   * Add release notes (can copy from CHANGELOG)
-   * **Publish** the release (this triggers CI/CD)
-
-**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.
-* For widgets: use widget tests. For business logic: use unit tests.
-* Code coverage should not decrease with new commits.
-
-### 📝 Changelog Maintenance
-
-* **Update `CHANGELOG.md`** with every user-facing change.
-* Format: `## [Unreleased] - YYYY-MM-DD` followed by `### Added`, `### Changed`, or `### Fixed`.
-
-### 🎨 UI Patterns (MUST READ BEFORE CHANGES)
-
-* **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.

+  - ThemeProvider now persists for app lifetime
+
+### Added
+- `@persistentRiverpod` annotation in `core/providers/annotations.dart`
+  - Reusable annotation for providers that should not auto-dispose
+  - Documented in ARCHITECTURE.md
+
+## [1.1.13] - 2026-01-04
+
+### Added
+- Settings page with Appearance, Navigation, and Account sections
+- Theme toggle in user profile dropdown (System/Light/Dark)
+- Theme syncs with API preferences on login
+- Default room preference syncs with backend
+
+### Changed
+- Theme changes now persist to both local storage and API
+
+## [1.1.12] - 2026-01-04
+
+### Changed
+- Control Room navigation reorganized:
+  - New "Stack" section with Containers and Proxy Hosts
+  - New "Data Management" section with PostgreSQL, Redis, Qdrant, Neo4j placeholders
+  - Removed: Networks, Volumes, Images (Portainer) and Redirections, Streams, Certificates (NPM)
+
+## [1.1.11] - 2026-01-04
+
+### Fixed
+- API client providers now use `keepAlive: true` to prevent Ref invalidation
+  - Fixes "DioException [unknown]: null" error on /security/users and other API pages
+  - AuthInterceptor's stored Ref was becoming invalid when provider auto-disposed
+
+## [1.1.10] - 2026-01-04
+
+### Changed
+- Removed page swipe transitions - all navigation is now instant (NoTransitionPage)
+
+## [1.1.9] - 2026-01-04
+
+### Changed
+- Moved health check to `/health` directory - URL is now `/health` instead of `/health.html`
+  - Enables NPM forward auth path exclusion for health endpoint
+
+## [1.1.8] - 2026-01-04
+
+### Changed
+- Dark background (`#1a1a2e`) on web/index.html to prevent white flash during auth redirects
+
+## [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

+  - 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
+

+# CLAUDE.md — tatlock-ui
+
+Flutter/Dart frontend for the homelab — the dashboard at `home.schweitz.net`. Riverpod state,
+Material 3, Go-Router. Built as a **Flutter web** app, served as compiled static assets by nginx
+in the `tatlock-ui` container. `pubspec.yaml` version **1.7.1+1**, package name `tatlock_ui`,
+Dart SDK `^3.10.4`.
+
+It is a **client**, not a service. It talks to core-api (:8083) and tatlock (:8000); it exposes
+no API of its own and has no `/openapi.json`.
+
+## Read first
+
+- **[PHILOSOPHY.md](PHILOSOPHY.md)** — the system vision and the architectural patterns all work
+  should move toward. The previous AGENTS.md made this a mandatory pre-work read and that
+  requirement is carried forward deliberately.
+- **[docs/UI_LAYOUT.md](docs/UI_LAYOUT.md)** — **read before touching the widget tree.** Check
+  `lib/shared/components/` for an existing component before building a new one, and look at how a
+  comparable feature already does it. Deviating from the established patterns is the main source
+  of drift here.
+- `docs/` also holds `ARCHITECTURE.md`, `API_INTEGRATION.md`, `TESTING.md`, `THEMING.md`,
+  `DATAGRID.md`, `DEPLOYMENT.md`.
+
+## Ports and where it runs
+
+| | |
+|---|---|
+| Container | `tatlock-ui`, `127.0.0.1:9999 -> 80` (nginx serving the web build) |
+| External | `home.schweitz.net` |
+| Backends | core-api `:8083`, tatlock `:8000` |
+
+The old AGENTS.md said the app is "available at `http://tower:8092`". **That is stale** — the
+published port is 9999, verified against `docker ps` on 2026-08-09.
+
+It also pointed at `portainer-core` for full-stack documentation. **`portainer-core` is
+deprecated** and must not be used as a source of infra facts; it was merged into
+`system-admin-toj/containers/`. The live inventory is `CONTAINERS.md` there.
+
+The Gitea SSO-bypass trick is real and still works: `http://localhost:3002` reaches Gitea
+directly, verified returning `{"version":"1.27.1"}`. Useful for reading a sibling repo's raw
+files without going through Authentik.
+
+## Layout
+
+`lib/main.dart` → `lib/app.dart`; `lib/core/` (api, auth, config, error, providers, semantics,
+theme), `lib/features/<room>/` (control_room, front_hall, media_room, parlor, security,
+settings), `lib/routing/`, `lib/shared/` (components, layouts, theme, widgets). 132 Dart files
+under `lib/`, 24 test files.
+
+## Establishing what is live — and the trap in it
+
+There is no `sys.modules` here and nothing to `docker exec` into: the container holds compiled
+assets, not source. The Dart analogue is a transitive walk of `import`/`export`/`part`
+directives from `lib/main.dart`, resolving `package:tatlock_ui/…` to `lib/…`. Run 2026-08-09:
+124 of 132 files reachable, 8 not.
+
+**Do not read that as a delete list. Five of the eight are the code that actually runs in
+production.** They are conditional-import targets:
+
+```dart
+import 'api_client_native.dart' if (dart.library.html) 'api_client_web.dart';
+```
+
+A naive walk captures the *first* string and misses the branch. Since this app ships as Flutter
+**web**, the `_web.dart` half is the live one and the `_stub`/`_native` half is the dormant one —
+the exact inverse of what the reachability count suggests. The five: `api_client_web.dart`,
+`web_utils_web.dart`, `url_strategy_web.dart`, `url_state_web.dart`,
+`iframe_view_web.dart`. Find them all with `grep -rn "if (dart.library" lib/`.
+
+That leaves three genuinely unreferenced files, and they are **not** all the same thing:
+
+| File | Status |
+|---|---|
+| `lib/core/auth/permission_gate.dart` | no reference anywhere in `lib/` or `test/` |
+| `lib/core/semantics/semantic_widget.dart` | no reference anywhere in `lib/` or `test/` |
+| `lib/features/control_room/stacks/data/models/stack_model.dart` | **referenced only by its own test** |
+
+The third is the interesting one: `stack_model_test.dart` imports and exercises it, so the suite
+is green and gives confidence about a model the app never uses. A passing test is not evidence a
+thing is wired in.
+
+Before deleting any of the three, check whether it is intended groundwork rather than debris —
+`TODO_AUTH_REFACTOR.md` describes an unimplemented auth redesign, and `permission_gate.dart` sits
+squarely in that area. Neither that file nor `PLAN.md` mentions it by name, so its status is
+**undetermined**, not dead. Ask before removing.
+
+## Tooling
+
+`flutter` and `dart` resolve from `/snap/bin`, which **is** on the non-interactive `PATH` — so
+bare commands work here (unlike `pql`, which needs its absolute path).
+
+```bash
+flutter pub get
+flutter test                 # 24 test files
+flutter analyze              # static analysis; analysis_options.yaml at the repo root
+flutter build web --release
+```
+
+**Always add tests for new code before committing** — happy path plus key edge cases, widget
+tests for widgets, unit tests for logic. Coverage should not decrease. Carried over from the
+previous AGENTS.md, which stated it as "no exceptions".
+
+Note there is **no CI test gate**: `.gitea/workflows/build.yml` triggers only on `v*` tag push
+and goes straight to build and release. `flutter test` runs locally or not at all.
+
+## Work tracking
+
+Work lives in **pql**, not a markdown TODO. **This repo's vault is standalone** — its tickets and
+its internal decisions live here in `.pql/` and `governance/`, and travel with a clone, because
+`.pql/changelog/` is committed and replayed by the git hooks (workspace D-15). The databases are gitignored
+and rebuildable with `pql plan rebuild`.
+
+`pql` is **not** on the non-interactive `PATH` — invoke it as `/home/jpmschweitzer/.local/bin/pql`.
+From inside this repo no `--vault` is needed: pql anchors at the nearest `.git/` ancestor, which
+is this repo.
+
+```bash
+/home/jpmschweitzer/.local/bin/pql ticket list        # this repo's open work
+/home/jpmschweitzer/.local/bin/pql plan whatsnext     # next unblocked item, with context
+/home/jpmschweitzer/.local/bin/pql decisions list     # this repo's own decisions
+```
+
+Stack-level decisions that constrain this app live in the **workspace** vault and need the flag:
+
+```bash
+/home/jpmschweitzer/.local/bin/pql --vault /mnt/media/Projects decisions list --domain tatlock-ui
+```
+
+Note `ticket new --decision D-N` resolves ids within **one** vault, so a ticket here cannot link
+to a workspace decision. Cite the id in the ticket body instead.
+
+`PLAN.md` and `TODO_AUTH_REFACTOR.md` predate this convention. Treat them as research notes;
+new work goes in pql.
+
+## Git
+
+- **History is linear — no merge commits.** Work on `main`, or a short-lived branch that is
+  fast-forwarded and deleted.
+- **Conventional Commits**: `feat:`, `fix:`, `refactor:`, `docs:`, `chore:`.
+- **Stage explicitly. Never `git add -A`** — denied by policy, and it sweeps in whatever else is
+  dirty.
+- **Every version increment gets a tag** — `vX.Y.Z`, on the `major.minor.patch` part, not the
+  build number.
+- Update `CHANGELOG.md` for every user-facing change.
+
+**`.claude/settings.local.json` is currently tracked in git here.** Contents are benign — a
+four-entry permission allow list, no `env` block, no secrets — but it is machine-local state that
+should not be shared. There is now a `.gitignore` rule for it, and **that rule is inert**: git
+applies ignore rules only to untracked paths, so edits still show in `git status` and still get
+committed. It starts working only after `git rm --cached .claude/settings.local.json`, which is a
+history decision and was deliberately left out of normalization.
+
+Consequence for checking: plain `git check-ignore` prints nothing for this path — it consults the
+index — which looks identical to "no rule exists". Use `--no-index` to test the rule itself.
+
+## Releasing
+
+1. Bump `version` in `pubspec.yaml` (the `major.minor.patch` part).
+2. Move `[Unreleased]` entries into a dated section in `CHANGELOG.md`.
+3. Stage by name, commit, tag `vX.Y.Z`, `git push origin main --tags`.
+4. Gitea CI builds the web app in Docker, pushes `:latest` and `:vX.Y.Z`; Watchtower deploys.
+5. Verify at `home.schweitz.net`, or `curl -I http://localhost:9999`.
+
+**Rollback:** in Portainer, point the image tag at the previous version.

+# 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

+### 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:
+
+```dart
+import 'package:tatlock_ui/core/providers/annotations.dart';
+
+// ✅ Correct - persists for app lifetime
+@persistentRiverpod
+Dio coreApiClient(Ref ref) { ... }
+
+@persistentRiverpod
+class ThemeNotifier extends _$ThemeNotifier { ... }
+
+// ❌ Wrong - auto-dispose can invalidate stored Ref
+@riverpod
+Dio coreApiClient(Ref ref) { ... }
+```

+## 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
+
+```dart
+import 'package:tatlock_ui/core/semantics/semantic_ids.dart';
+
+// Wrap interactive widgets with Semantics
+Semantics(
+  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`
+
+### Current Rooms
+
+| Room | ID | Default Route |
+|------|-----|---------------|
+| Front Hall | `front-hall` | `/front-hall` |
+| Control Room | `control-room` | `/control-room/containers` |
+| Security | `security` | `/security/users` |

+| Media Room | `media-room` | `/media-room` |

+# 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

+# Decisions, Questions, Rejected
+
+This directory holds structured planning records that pql parses
+into pql.db. Each record is a `### [DQR]-N: Title` heading inside
+a markdown file. Files live in three per-type subdirectories:
+
+- `decisions/<domain>.md` — confirmed design decisions
+- `questions/<domain>.md` — open questions that may resolve into
+  decisions or rejected proposals
+- `rejected/<domain>.md` — rejected proposals (kept for the audit
+  trail)
+
+The parser infers domain from the filename stem and record type
+from the parent subdirectory.
+
+D-records that propose implementation work link to `initiative`-type
+tickets via `decision_ref`. Run `pql decisions show <id>
+--with-tickets` to inspect implementation status.
+
+## Recommended domains
+
+Start with this canonical set; create files as records land in
+each domain:
+
+- **architecture** — structural commitments (storage, layering,
+  languages, libraries)
+- **process** — team workflow (commits, branches, releases, reviews)
+- **design** — user-facing surface (UX, UI, public APIs)
+- **coding-conventions** — team-internal code shape (style, lint,
+  file layout)
+- **testing** — quality strategy (coverage, layers, gates)
+
+You might also want, project-permitting:
+
+- `accessibility` — if you ship user-facing software
+- `security` — if you handle user data or network surfaces
+- `licensing` — if you release open-source or commercial
+- `documentation` — if user-docs are non-trivial
+- `deployment` — if shipping is non-trivial
+- `performance` — if you have perf budgets / SLOs
+
+<!-- pql:records (auto-generated; do not edit manually) -->
+
+## Decisions
