Contain the Litestream sidecar's write access to the database volume

Review finding F-01: the litestream service mounts nestquest-db
read-write. A read-only mount is not possible: Litestream 0.5.17 fails
with "unable to open database file (14)" on a :ro mount, even with
meta-path moved to a separate writable volume, because it writes its
_litestream_seq/_litestream_lock tables into the database, opens the
-wal/-shm files for writing and checkpoints the WAL.

Keep the write mount and contain it instead: run as the API's non-root
volume owner (999:999) with a read-only root filesystem (tmpfs /tmp),
no-new-privileges and all capabilities dropped. Document why in
compose and api/README.md, including the key chown the uid change needs.

 # NestQuest Release Notes
 
-## Unreleased
+## Version 0.6.0 — 2026-09-23
 
-- **Storage layer extraction (task d0b691d8):** the SQLite storage layer
-  (schema, migrations, db, store, const, recurrence, DAOs) is bundled
-  under `custom_components/nestquest/core/`, with the integration's
-  original module names preserved as re-export shims.
-- **Logger namespace change (breaking for logging configuration):** the
-  migrations runner now logs under
-  `custom_components.nestquest.core.migrations` instead of
-  `custom_components.nestquest.migrations`. Users who tuned the old
-  logger name (e.g. in `logger.yaml` or `configuration.yaml`) must
-  update the entry to keep that level, as the old name no longer
-  receives migration log output.
-- **Additional logger namespace moves:** the children registry and the
-  admin allowlist business layers now log under
-  `custom_components.nestquest.core.children` and
-  `custom_components.nestquest.core.admin_allowlist` respectively
-  (moved with the engines/business-layer extraction, task 510c1f78).
-  The parent `custom_components.nestquest` logger still catches both,
-  so users who tune the parent rather than the leaf names are
-  unaffected; only users who pinned a leaf logger name by its old
-  spelling need to update.
+### Scope
+
+Sixth release of NestQuest, promoting the re-imagined architecture
+(Features 15, 16, 18 and 20) and the foreground development-orchestration
+tooling from `dev` onto 0.5.0. This is a major architectural change: the
+Home Assistant integration becomes a thin client of a standalone NestQuest
+API service that owns the database.
+
+- **Feature 15 — Domain Core Extraction:** all domain code (schema,
+  migrations, database access, the DAOs, the pure recurrence/presence
+  engines, materialization, completion, the SSE-free event payload
+  builders, the panel snapshot builder, the children/definitions/allowlist
+  business layers, and an explicit settings object) now lives in a
+  Home-Assistant-free package bundled inside the integration at
+  `custom_components/nestquest/core/`. The SQLite schema and migration
+  versions are unchanged, so an existing `nestquest.db` opens without
+  migration. Covered by a no-Home-Assistant end-to-end smoke test.
+  (Tasks d0b691d8, 510c1f78, 4dd8f870, 628473ad.)
+- **Feature 16 — NestQuest API Service:** a standalone FastAPI service
+  (`api/`) that imports `core/` and is the only writer of the database.
+  Panel plane (`/api/v1/panel/*`) is authenticated by a static service
+  token: household snapshot and an idempotent complete route. Admin plane
+  (`/api/v1/admin/*`): children, quest definitions, presence
+  schedule/override, uncomplete, regenerate, history query + CSV export,
+  and settings — authenticated by an Authentik OIDC JWT (issuer, audience,
+  JWKS signature and expiry) plus membership in `nestquest-admins`, with
+  the panel service token rejected outright. A server-sent-events stream
+  publishes the quest-completed, quest-uncompleted, quest-missed and
+  child-day-complete transitions; the missed sweep runs in the API with a
+  cross-process-safe watermark. `/health` and the OpenAPI document are
+  served. (Tasks 042dfc5c, ae7e90ae, 1860ef76, 4d7bae00, 44c93cfd,
+  e70e6bfb, 0f2afb29, e4845baa, b586a2f1, e4a9d31b, da0226b3, 2d2dda53,
+  2b3de7e5, 9047a97b, 9a118da9, 058c7b69, a232c4f5.)
+- **Feature 18 — HA Integration as API Client:** the integration no longer
+  owns a database. It polls `GET /api/v1/panel/snapshot` and builds the
+  existing sensors (entity ids and per-child instance payload shape
+  unchanged), subscribes to the SSE stream and re-fires the four HA bus
+  events, proxies `nestquest.complete_quest` to the panel complete route,
+  and caches the last-good snapshot so a brief API outage does not blank
+  the panel. The HA admin services and the service permission gate are
+  removed; only the panel completion path remains. (Tasks 37d5e806,
+  6e70d166, b1ed9c45, 47c7c90e, d25b875f, d04f5bf3, ad67fc44.)
+- **Feature 20 — Zero-Config Panel Dashboard:** the panel installs with no
+  hand-written card YAML and no manual dashboard creation. The cards
+  auto-discover children from a household entity attribute (ordered by the
+  API's `sort_order`), a Lovelace dashboard strategy generates the
+  party-board view and one quest-log view per child at render time with
+  computed navigation paths, and the integration registers the dashboard
+  on first setup. Navigation and the panel transitions match the design
+  mockups. (Tasks 1b6d91d2, c859af23, c2d4dd8e, 107b8fbe, 50067c1f,
+  fc69c940, 67775be9.)
+- **Development orchestration tooling:** durable OpenCode controller and
+  role launchers, the foreground terminal orchestrator, the independent
+  review/approval gates, and the automatic release-preparation policy.
+
+### Requirements
+
+- Minimum Home Assistant version: **2024.6.0**.
+- A running NestQuest API service, reachable at the base URL and panel
+  service token configured in the integration options. The API service
+  source ships in `api/`; there is no container image, compose file or
+  deployment runbook in this release, and Feature 17 — the deployment
+  (TLS reverse proxy, Authentik, network separation, backups) — is **not**
+  part of this release and must be completed before the integration is
+  functional. See `docs/ARCHITECTURE.md` for the target design.
+
+### Breaking changes
+
+- **The HA integration no longer owns a database.** It reads exclusively
+  from the NestQuest API. The local `nestquest.db` is no longer opened,
+  migrated or written by the integration (the file is left untouched on
+  disk). Without a reachable API the entities become unavailable after the
+  configured staleness threshold; the panel serves the last-good snapshot
+  in the meantime.
+- **HA admin services are removed** (`uncomplete`, quest-definition
+  create/update/set-active, presence pattern/override, CSV export,
+  `manage_child`, `regenerate`) and the HA-side permission gate is gone.
+  Admin operations move to the API, and — once Feature 19 lands — the
+  admin PWA. Any automation that called an admin service must be
+  repointed at the API.
+- **Logger namespaces moved** under `custom_components.nestquest.core.*`:
+  the migrations runner now logs under
+  `custom_components.nestquest.core.migrations` (previously
+  `custom_components.nestquest.migrations`), and the children registry and
+  admin allowlist log under `custom_components.nestquest.core.children` and
+  `custom_components.nestquest.core.admin_allowlist`. The parent
+  `custom_components.nestquest` logger still catches all three; only users
+  who pinned a leaf logger name by its old spelling must update.
+- **The panel installs with no configuration.** `child_order`,
+  `quest_log_path` and `board_path` are no longer required (an explicit
+  value still wins). The integration registers a `custom:nestquest-party`
+  dashboard on setup; point TouchHub at it.
+- **Schema is unchanged at version 7** — no migration runs on upgrade.
+
+### Known Limitations
+
+- **Feature 17 (API deployment and identity) is not in this release.** The
+  API service source ships in `api/`, but no container image, compose
+  file, TLS reverse proxy, Authentik application/provider/`nestquest-admins`
+  group, proven network separation of the panel routes, or backup/restore
+  is included. Feature 17's containerization groundwork was completed on
+  its own feature branch, which is **not** merged into `dev` and therefore
+  is not part of this release. Until that deployment is completed the
+  integration has nothing to talk to.
+- **Feature 19 (admin PWA) is not in this release.** There is no admin UI
+  in 0.6.0; admin operations are reachable only through the API directly.
+- Moving the household database from Home Assistant to the API box is a
+  manual file copy (the schema is unchanged).
+- Single household; single API service.
+
+### Rollback
+
+Schema version is unchanged (7), so no migration is involved in either
+direction. Nevertheless **back up `nestquest.db` (plus `-wal`/`-shm`)
+before upgrading**: 0.6.0 never touches it, and a downgrade to 0.5.0
+resumes using exactly that file.
+
+**HACS installs:**
+
+1. Downgrade via HACS (HACS > Integrations > NestQuest > Redownload > 0.5.0).
+2. Restart Home Assistant.
+
+**Manual installs:**
+
+1. Replace `custom_components/nestquest/` with the 0.5.0 tree.
+2. Restart Home Assistant.
+
+**Repository operators:** git-revert the 0.6.0 release merge on `main`.

+# NestQuest API
+
+Standalone FastAPI service owning the NestQuest database (Feature 16).
+Served with ``uvicorn --factory api.app:create_app``; configuration is
+environment-supplied (``api/config.py``) and every variable is required.
+
+## Runtime dependencies
+
+``api/requirements.txt`` is the API deployable's OWN dependency
+manifest (fastapi, uvicorn, pyjwt[crypto], httpx) — deliberately kept
+out of the integration's ``pyproject.toml`` dev group, which exists only
+so the monorepo test venv can run the API tests.
+
+## Container deployment (scaffold)
+
+The image is built from the repository ROOT context (the API loads the
+bundled domain core from ``custom_components/nestquest/core/`` by file
+location, so both trees must be in the build context):
+
+    docker build -t nestquest-api:latest .
+
+Run it with compose — the SQLite file lives on the named volume
+``nestquest-db`` so recreating the container keeps household data:
+
+    cp deploy/.env.example deploy/.env   # then fill in real values
+    docker compose -f deploy/compose.yaml up -d --build
+
+``deploy/.env`` is git-ignored and supplies the secrets (panel service
+token, Authentik OIDC settings); ``NESTQUEST_DB_PATH`` is fixed to
+``/var/lib/nestquest/nestquest.db`` by compose.
+
+The published port binds ``NESTQUEST_BIND_ADDRESS`` from
+``deploy/.env`` and defaults to ``127.0.0.1`` (localhost only). In
+production TLS is terminated by the shared Traefik reverse proxy,
+which serves ``https://nestquest.cubecraftlabs.com`` (Let's Encrypt,
+auto-renewed, HTTP redirected to HTTPS) and forwards to the API box

+## Continuous backup (Litestream)
+
+Compose also runs a ``litestream`` sidecar
+(``litestream/litestream:0.5.17``, config ``deploy/litestream.yml``).
+It mounts the same ``nestquest-db`` volume and continuously replicates
+``/var/lib/nestquest/nestquest.db`` over SFTP to the Synology NAS
+``CubeCraft-SRVR1`` (``joshua@10.60.1.50``), directory
+``/volume1/homes/Joshua/nestquest-backups`` (``/homes/Joshua/...`` in
+the NAS's chrooted SFTP view) — so the backup is outside the Docker
+host and its volume. A snapshot is taken daily and a week of
+snapshots plus incremental changes is retained; the NAS host key is
+pinned in the config.
+
+The SFTP login uses a dedicated keypair that lives only on the API
+box and is git-ignored. Create it once, before ``up``:
+
+    ssh-keygen -t ed25519 -N "" -C nestquest-litestream -f deploy/litestream_key
+
+then append ``restrict `` + the contents of ``deploy/litestream_key.pub``
+to ``joshua@10.60.1.50:~/.ssh/authorized_keys``. Compose mounts the
+private key read-only at ``/etc/litestream/sftp_key``. The sidecar runs
+as uid/gid 999 (the API's ``nestquest`` user), so give it the key:
+
+    sudo chown 999:999 deploy/litestream_key && chmod 600 deploy/litestream_key
+
+The sidecar needs WRITE access to the database volume: Litestream adds
+its own ``_litestream_seq``/``_litestream_lock`` tables to the database,
+writes the ``-wal``/``-shm`` files and checkpoints the WAL, and fails
+with "unable to open database file" on a read-only mount. That access
+is contained rather than removed — the sidecar runs as the non-root
+volume owner with a read-only root filesystem, ``no-new-privileges``
+and all Linux capabilities dropped.
+
+Check replication with
+``docker compose -f deploy/compose.yaml logs litestream`` or
+``docker compose -f deploy/compose.yaml exec litestream litestream ltx /var/lib/nestquest/nestquest.db``.
+To restore (high level): stop the ``api`` service, run
+``litestream restore -config /etc/litestream.yml -o <new path>
+/var/lib/nestquest/nestquest.db`` from a litestream container with the
+same mounts, verify the restored file, move it into place on the
+volume (removing any stale ``-wal``/``-shm`` files), and start ``api``
+again.

+# NestQuest Architecture
+
+Status: approved direction (2026-09-21). This document supersedes the
+single-process design implied by Features 01–14, in which the Home Assistant
+integration owned the database and the parent admin surface was planned as a
+Lovelace card inside Home Assistant.
+
+## 1. Why this changed
+
+The original design put everything inside the Home Assistant integration: the
+SQLite database, the business logic, the kid panel cards, and (planned) the
+parent admin card. Three problems surfaced:
+
+1. **The panel needed hand configuration.** Standing up the kid panel required
+   hand-writing card YAML (`child_order`, `quest_log_path`, `board_path`) and
+   hand-creating a Lovelace dashboard. A fresh install rendered nothing.
+2. **The admin surface fought Home Assistant.** The admin design
+   (`design/ADMIN-SPEC.md`) is drawn at 390×844 — it is a phone app. Trapping it
+   inside a Lovelace card meant fighting HA's UI constraints for a mobile-first
+   experience.
+3. **Data was locked to one process.** A standalone admin web app cannot reach a
+   SQLite file inside Home Assistant's config directory.
+
+The re-imagined design keeps the panel in Home Assistant (TouchHub loads an HA
+dashboard), moves data ownership to a standalone API service, and promotes the
+admin surface to a standalone mobile-first PWA.
+
+## 2. Target architecture

+```
+
+One owner of the data (the API). Two clients (the HA integration, the PWA).
+
+## 3. Data ownership
+
+**The API service is the only writer.** The HA integration never opens the
+database; it reads a snapshot and posts completions. This removes the
+two-writer problem entirely.
+
+- **Storage:** SQLite on the API box. Single household, trivial concurrency,
+  and the existing schema, migrations, and DAO tests are already SQLite. Postgres
+  buys nothing at this scale.
+- **Schema:** unchanged. The cutover from the current HA-hosted database is a
+  file copy — same schema, same migration version.
+- **Backups:** continuous replication (e.g. Litestream) plus a proven restore.
+  A configured-but-untested backup is not a backup.
+
+## 4. Authentication: two planes
+
+The kid panel and the admin PWA have opposite trust levels, so they use
+separate credentials and separate network exposure.
+
+### Panel plane (machine)
+
+- **Credential:** a static service token.
+- **Exposure:** `/api/v1/panel/*` is reachable **only from the LAN**.
+- **Grants:** read the snapshot, and the single open write — complete a quest as
+  `actor: panel` with the tapped `actor_child_id`.
+- **Refused:** admin routes reject the service token outright, not merely as a
+  non-admin. The internet cannot reach these routes at all.
+
+This preserves the original fail-closed boundary: the kiosk can complete a
+quest and nothing else.
+
+### Admin plane (human)
+
+- **Credential:** an Authentik OIDC JWT (authorization code + PKCE).
+- **Exposure:** `/api/v1/admin/*` is internet-facing behind Authentik.
+- **Grants:** everything a parent can do — definitions, assignment, presence,
+  children, un-complete, history, export, settings, regenerate.
+- **Gate:** the API validates the JWT (issuer, audience, JWKS signature, expiry)
+  and requires membership in the `nestquest-admins` group. The Authentik group
+  is the single source of truth for "who is a parent", replacing the
+  integration-side admin allowlist.
+
+## 5. Components
+
+### `core/` — domain library
+
+The extracted domain layer: schema, migrations, database access, DAOs, the pure
+recurrence and presence engines, materialization, completion, event payload
+construction, and the children/definitions/allowlist business layers. **No
+Home Assistant imports.** Consumed by both the API and (during transition) the
+integration. This is where the ~1500 existing tests live after extraction.
+
+### `api/` — NestQuest API
+
+A FastAPI service importing `core/`. Owns the database. Serves the panel and
+admin planes, validates Authentik tokens, and publishes a transition event
+stream (SSE) that the integration consumes. No business logic in route handlers.
+
+### `custom_components/nestquest/` — HA integration (client)
+
+A thin client. Polls the snapshot and builds the existing sensors; subscribes to
+the SSE stream and re-fires the four HA bus events; proxies the panel completion.
+Holds a last-good snapshot cache so a brief API outage does not blank the panel.
+Owns no database and no business logic.
+
+### `panel/` — Lovelace cards and dashboard strategy
+
+The two kid-facing Lit cards plus a dashboard strategy that generates the panel
+views at render time. Cards auto-discover children, so no `child_order` is
+required; the strategy computes navigation paths, so `quest_log_path` and
+`board_path` are not required.
+
+### `admin/` — Admin PWA
+
+A React progressive web app implementing `design/ADMIN-SPEC.md`, authenticated
+via Authentik OIDC, installable on a phone. The only admin surface.
+
+## 6. Zero-configuration panel
+
+A fresh install should show the panel with no YAML:
+
+1. **Auto-discovery.** The party-board card reads an ordered child list from a
+   household entity attribute instead of a configured `child_order`.
+2. **Dashboard strategy.** A Lovelace strategy generates a party-board view and
+   one quest-log view per child, wiring navigation between them, so paths are
+   computed rather than configured. Explicit configuration still wins if a user
+   supplies it.
+3. **Auto-registration.** The integration registers the dashboard on first
+   setup, so there is no manual dashboard step.
+
+## 7. Home Assistant surface preserved
+
+The re-imagining must not break what already works:
+
+- **Sensors:** the per-child and household sensor entity_ids and the per-child
+  instance attribute payload shape are unchanged. The panel cards and the four
+  blueprints depend on them.
+- **Events:** the four HA bus events (`nestquest_quest_completed`,
+  `nestquest_quest_uncompleted`, `nestquest_quest_missed`,
+  `nestquest_child_day_complete`) keep firing with their documented payloads.
+  They are now driven by the API's transition stream rather than by local
+  service handlers.
+- **Blueprints:** the morning summary, afternoon reminder, end-of-day report, and
+  day-complete celebration continue to work with no change.
+
+## 8. Events without an HA token on the API box
+
+The API publishes transitions on an SSE stream; the integration subscribes and
+re-fires the HA bus events locally. This deliberately avoids storing a Home
+Assistant long-lived token on the API box, which would grant full HA access.
+
+## 9. Migration phases
+
+Mapped to the Maestro features:
+
+| Phase | Feature | Outcome |
+|---|---|---|
+| 1 | 15 — Domain Core Extraction | `core/` runs with no HA imports; one implementation of the rules |
+| 2 | 16 — NestQuest API Service | Panel and admin planes served with two-plane auth |
+| 3 | 17 — API Deployment and Identity | TLS, Authentik, backups, network separation |
+| 4 | 18 — HA Integration as API Client | Integration becomes a client; entity/event surface preserved |
+| 5 | 19 — Admin PWA | Mobile-first React PWA replaces the admin card |
+| 6 | 20 — Zero-Config Panel Dashboard | Panel installs itself; navigation and animations match the mockups |
+
+Cutover: copy the existing SQLite file to the API box (same schema).
+
+## 10. Locked decisions
+
+- **API on its own box** — separate from Home Assistant.
+- **Authentik** (`https://auth.cubecraftlabs.com`) for admin identity; a
+  `nestquest-admins` group is the admin source of truth.
+- **Single household** — no tenant column, no multi-household auth.
+- **React** for the admin PWA.
+- **Drop the HA admin services** — the PWA is the only admin surface. The panel
+  completion path stays.
+- **SQLite on the API box** initially; Postgres only if multi-household ever
+  becomes real.
+
+## 11. Preserved vs. changed
+
+**Preserved:** the tested Python domain layer, the panel card designs and
+tokens, the sensor and event contract, the completion model, the append-only
+event log, the panel's fail-closed "complete only" boundary.
+
+**Changed:** data ownership moves to the API; the integration becomes a client;
+the admin card becomes a PWA; panel cards become config-free with a
+strategy-generated dashboard.
+
+**New:** the API service, Authentik-gated admin auth, the PWA, and a
+last-good-snapshot cache in the integration.
+
+**Cost:** two new deployables (the API and the PWA) and one new box. Accepted
+knowingly in exchange for a self-installing panel, an admin surface that is not
+fighting HA's UI, and a data layer with real auth in front of it.

+
+``POST /api/v1/admin/presence-overrides/consequence`` answers, BEFORE an
+override is saved, how many of the child's upcoming open quest
+instances saving it would remove (``{"removed": N}``) — the ADMIN-SPEC
+§6 "This removes N upcoming tasks" warning.  These tests exercise it
+against the ASGI app with the shared stubbed-JWKS harness
+(:mod:`tests.admin_jwt_harness`):
+
+- a two-week custody pattern (present the whole first week of the
+  cycle, absent the whole second) where an absent override over a
+  known span removes an EXACT number of instances;
+- ranges that remove nothing (already-absent days, a present
+  override) count 0;
+- an instance with a completion event inside the range is NOT counted
+  (D-005 — regeneration never deletes it);
+- a ``skip_on_away = false`` definition contributes nothing;
+- the count MATCHES a direct materialise comparison: the override is
+  then actually created (which regenerates the child) and the removed
+  open future instances are counted from the database;
+- the preview writes nothing;
+- the four auth outcomes, an unknown child 404 and a malformed range
+  422.
+
+The cycle is anchored on the REAL host "today" (the create route's
+regeneration reads the host clock, so the comparison test cannot pin
+it): days today..today+6 are cycle week 0 (present every day), days
+today+7..today+13 week 1 (absent every day), today+14 week 0 again.
