 # NestQuest Release Notes
 
-## Unreleased
+## Version 0.9.0 — 2026-09-26
 
-- **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
+
+Minor release carrying expanded, customisable task icons — Lucide, Font Awesome
+Free and emoji — onto `main`.
+
+- **Namespaced icon keys:** a quest definition's `icon` now accepts
+  `lucide:<kebab-name>`, `fa:<kebab-name>` and `emoji:<grapheme>`. A legacy bare
+  name (e.g. `dog`) is read as `lucide:dog`, so existing rows keep working with
+  no stored-data migration. The strict write validator rejects an unknown
+  namespace, a malformed name, an over-cap or markup-bearing emoji payload, and
+  `javascript:`. (PRs #241, #249.)
+- **Shared icon registry:** one canonical set — the curated Lucide set plus a
+  curated Font Awesome Free solid subset — generates identical,
+  framework-agnostic registry modules for the admin and panel bundles, guarded by
+  a drift test. There is no CDN and no runtime fetch, and only the curated Font
+  Awesome glyphs are shipped. (PR #242.)
+- **Admin PWA picker:** the definition edit sheet offers the Lucide set, the
+  Font Awesome subset and an emoji input; a selection stores the namespaced key
+  and an existing namespaced or legacy icon pre-fills correctly. The definition
+  list renders all three forms with a fallback glyph. Editing a definition whose
+  stored icon is a legacy value no longer resubmits the unchanged icon.
+  (PRs #243, #250.)
+- **Kids' panel:** open quest cards render the definition's icon (Lucide stroked,
+  Font Awesome filled, emoji as text) with the existing star fallback; the sealed
+  card keeps its star/seal glyph. (PR #245.)
+- **Docs and attribution:** ADMIN-SPEC and PANEL-SPEC describe the namespaced
+  model; `THIRD-PARTY-NOTICES.md` records Font Awesome Free (icons CC BY 4.0,
+  fonts SIL OFL 1.1, code MIT) and Lucide (ISC). (PR #246.)
+
+### Upgrade note
+
+The database schema is unchanged at version **9**; no migration or backup step
+is needed beyond the 0.8.0 note. This release adds no runtime dependency — the
+icon path data is embedded in the shipped bundles at build time.
+
+### Requirements
+
+Home Assistant 2024.6.0 or newer. Install through HACS from the
+`Maniacs-Mansion/NestQuest` GitHub mirror (kept current by the Gitea push
+mirror).
+
+## Version 0.8.0 — 2026-09-25
+
+### Scope
+
+Minor release carrying the multi-pattern presence model (schema 9), the
+Sunday-first calendar week, and the create-materializes fix, plus the
+definition start-date field, onto `main`.
+
+- **Multiple presence patterns per child (schema 9):** a child now has zero or
+  more presence patterns instead of at most one. Each pattern has a name, a kind
+  (`home` or `away`), its own cycle length (1–4 weeks), its own anchor date and a
+  per-week weekday set. Evaluation is first-match-wins — overrides, then away,
+  then home, then absent when the child has at least one home pattern, else
+  present. Migration 9 copies each existing schedule into a `home` pattern named
+  "Home schedule" and drops the old `presence_schedules` table. (PRs #231, #232.)
+- **Sunday-first calendar week:** the admin Schedule month grid and the
+  Definitions weekday picker now render weeks Sunday-first; the stored/API
+  weekday numbering is unchanged (Monday=0..Sunday=6). (PR #230.)
+- **Fix — newly created tasks materialize immediately:** creating a quest
+  definition now regenerates its future instances over the rolling horizon, so a
+  new task reaches the panel without waiting for an unrelated write. (PRs #235,
+  #236.)
+- **Definition start date:** the definition edit sheet gains a Start date field
+  so a task can be scheduled to begin on a future date. (PRs #237, #238.)
+- **Docs:** the multi-pattern decision (D-016), the migration-9 rollback step in
+  the runbook, and the ADMIN-SPEC Schedule section. (PRs #233, #234.)
+
+### Upgrade note
+
+This release runs schema version **9**. Version 0.7.1 refuses a version-9
+database, so take a copy of the SQLite file (or note the Litestream generation)
+before the first start on 0.8.0 if you need a rollback path.
+
+### Requirements
+
+
+## Version 0.7.1 — 2026-09-24
+
+### Scope
+
+Patch release bringing the admin PWA follow-ups and its hosting deployment from
+`dev` onto 0.7.0.
+
+- **Feature 24 — Admin PWA Hosting:** the admin PWA's static hosting is now
+  reproducible from the repository — `deploy/pwa/Dockerfile` (multi-stage, pinned
+  `node`/`nginx` base images by digest, `VITE_AUTHENTIK_CLIENT_ID` /
+  `VITE_AUTHENTIK_ISSUER` / `VITE_API_BASE_URL` build args), `deploy/pwa/nginx.conf`
+  (SPA fallback plus a source allow-list for the reverse proxy and the host), a
+  `pwa` service in `deploy/compose.yaml` published on `:8081`, and a
+  `deploy/RUNBOOK.md` section describing the build/serve and the Traefik
+  `nestquest-app` router. (PRs #220, #221.)
+- **Feature 19 follow-up — Manage children:** the Today header's Settings button
+  now opens a Settings screen. Its **Children** section lists the household's
+  children and lets a parent add (POST `/api/v1/admin/children`), edit
+  (PATCH `.../{id}`), activate/deactivate (PATCH `.../{id}/active`) and reorder
+  them (POST `.../reorder`). (PRs #222, #223.)
+- **Feature 19 follow-up — Settings preferences:** the same screen has a
+  **Preferences** section for the planning horizon, day rollover time, notify
+  target, the morning/afternoon/end-of-day notification times and their toggles,
+  and celebration, read from `GET /api/v1/admin/settings` and saved with a partial
+  `PATCH` of only the changed fields. (PRs #224, #225, #226.)
+
+### Requirements
+
+- Minimum Home Assistant version: **2024.6.0**.
+- A running NestQuest API service as in 0.7.0 (the Feature 17 deployment); the
+  `admin/` PWA is served from the owner's deployment at
+  `https://nestquest.cubecraftlabs.com`, not by HACS.
+
+### Breaking changes
+
+- **None.** The schema is unchanged at version 8 and no migration runs.
+  `custom_components/` is unchanged from 0.7.0 apart from the manifest
+  release-version metadata — no Home Assistant entity, service, event or
+  automation surface changes. This release adds admin PWA screens and deployment
+  artifacts only.
+
+### Known Limitations
+
+- **HACS does not ship the admin PWA or the deployment artifacts.** HACS copies
+  only `custom_components/nestquest`, so upgrading via HACS changes nothing
+  functional over 0.7.0; the PWA screens and hosting are deployed from `admin/`
+  and `deploy/` per the runbook.
+- Serving the PWA and API still requires the Feature 17 deployment (host, reverse
+  proxy, Authentik, backup target) as documented in `deploy/RUNBOOK.md`.
+- **Feature 12's TouchHub/DAKOS runbook task remains physically unverified**
+  (needs the wall panel).
+- The Settings UI does not expose resetting a field to its default with `null`.
+
+### Rollback
+
+Schema is unchanged (8), so no migration is involved in either direction.
+`custom_components/` is unchanged from 0.7.0 apart from the release-version
+metadata; rolling back the integration is a plain swap, and the PWA/hosting can be
+redeployed from the 0.7.0 tree.
+
+**HACS installs:** HACS > Integrations > NestQuest > Redownload > 0.7.0, then
+restart Home Assistant.
+
+**Manual installs:** replace `custom_components/nestquest/` with the 0.7.0 tree,
+then restart Home Assistant.
+
+**Repository operators:** git-revert the 0.7.1 release merge on `main`.
+
+## Version 0.7.0 — 2026-09-24
+
+### Scope
+
+Seventh release of NestQuest, promoting the re-imagined architecture's admin
+surface from `dev` onto 0.6.0: the API deployment and identity layer, the
+admin-plane API work, and the standalone admin PWA that uses them.
+
+- **Feature 17 — API Deployment and Identity:** the NestQuest API is packaged as
+  a container (`Dockerfile`, `deploy/compose.yaml`, pinned base image and exact
+  dependencies) and deployed behind a TLS reverse proxy (the shared Traefik, ACME
+  via the Cloudflare DNS-01 challenge); the Authentik application, OIDC provider
+  and `nestquest-admins` group are wired and the API validates the provider's
+  issuer/audience/JWKS (RS256); the panel plane is restricted to the Home
+  Assistant box while the admin plane is internet-facing behind Authentik;
+  continuous backup runs as a contained Litestream sidecar over SFTP to a NAS and
+  a restore is proven; a deployment runbook (`deploy/RUNBOOK.md`) and the
+  host-firewall unit (`deploy/systemd/nestquest-api-firewall.service`) ship.
+  (PRs #183, #214, #215, #216, #218.)
+- **Feature 19 — Admin PWA:** the parent-facing admin surface is now a
+  standalone mobile-first React progressive web app (`admin/`), implementing
+  `design/ADMIN-SPEC.md`: Authentik OIDC authorization-code + PKCE login with
+  an explicit refusal for a user outside `nestquest-admins`; an installable
+  PWA (manifest + service worker); and the Today, Definitions, Schedule and
+  History screens. Every mutating action goes through the API admin routes;
+  the API remains the security boundary (D-003/D-012). Today shows the
+  household snapshot; Definitions supports create/edit with multi-select
+  assignees, a recurrence rule with interval and per-window due times, a
+  skip-on-away toggle, a shipped Lucide icon subset and a backend-computed
+  occurrence preview; Schedule has a presence month grid (cycle position from
+  the anchor date, never ISO parity, D-004) and an override editor with a live
+  "removes N upcoming tasks" consequence count; History has All/Reversals/
+  Missed filters, day-grouped rows, per-period stats, CSV export and the
+  append-only footer. Undo reverses a completion, and live updates arrive over
+  the admin SSE stream without a manual reload. (PRs #187–#210, plus the
+  feature-review fix #212.)
+- **Feature 21 — Admin Today Snapshot API:** `GET /api/v1/admin/snapshot`
+  serves the Today view's household snapshot on the admin plane (reusing the
+  core snapshot builder with missed instances included, D-009). (PRs #190/#191.)
+- **Feature 22 — Admin Definitions Read and skip_on_away:**
+  `GET /api/v1/admin/quest-definitions` lists all definitions (active and
+  inactive), and a persisted per-definition `skip_on_away` boolean is accepted
+  by create/update and honoured by materialization. Adds an optional
+  `assignee_child_ids` to the edit route so the PWA can reassign children.
+  (PRs #193, #194, #196, #197.)
+- **Feature 23 — Admin API Completion (preview, presence, live):** a bounded
+  rule occurrence-preview route; presence-schedule and presence-override
+  reads; a live override consequence count computed from the same core
+  generator the materializer uses; and an admin-plane transition SSE stream
+  (`GET /api/v1/admin/events`) off the one in-process publisher. (PRs
+  #199–#203.)
+
+### 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 deployable ships in this
+  release: `Dockerfile`, `deploy/compose.yaml` (API + a contained Litestream
+  backup sidecar), `api/requirements.txt`, the host-firewall unit and
+  `deploy/RUNBOOK.md`. Deploying it needs a host, the DNS/TLS path and the
+  Authentik/Synology services described in the runbook.
+- The admin PWA is built to run at `https://nestquest.cubecraftlabs.com` behind
+  Authentik. Serving the built `admin/` static bundle at that hostname is part of
+  the deployment described in the runbook.
+
+### Breaking changes
+
+- **Schema version advances 7 → 8.** Migration 8 adds the additive
+  `skip_on_away` column to `quest_definitions` (default 1, so every existing
+  definition keeps today's skip-when-absent behaviour). The migration runs on
+  the first start of this version.
+- **Once migrated, a plain downgrade to 0.6.0 is impossible** — older builds
+  refuse a newer schema version. **Back up `nestquest.db` (plus `-wal`/`-shm`)
+  before upgrading**; see Rollback.
+- No Home Assistant entity, service, event or automation surface changes in
+  this release. The API's new admin routes are additive.
+
+### Known Limitations
+
+- **The API and its identity/backup layer are deployed by the owner's
+  infrastructure, not by this release alone.** The deployment artifacts and
+  runbook ship here, but a running service still requires the host, the shared
+  reverse proxy, the Authentik application/provider/`nestquest-admins` group, the
+  backup target and the panel/admin network separation to be in place as the
+  runbook describes.
+- **Serving the admin PWA is still outstanding.** `admin/` builds and is
+  unit/integration tested and the API it talks to is live, but the built static
+  bundle must still be hosted at `https://nestquest.cubecraftlabs.com` behind
+  Authentik; until then the PWA is not reachable end-to-end.
+- **Feature 12's TouchHub/DAKOS runbook task remains physically unverified**
+  (needs the wall panel).
+- Moving the household database from Home Assistant to the API box is a manual
+  file copy (the schema is unchanged by that move beyond the v8 migration).
+- Single household; single API service.
+
+### Rollback
+
+**Schema version advances 7 → 8.** Migration 8 is additive, but a migrated
+database **cannot** be read by 0.6.0 or earlier (they refuse a newer schema
+version). The database is owned and migrated by the **NestQuest API service**,
+not by Home Assistant: it is the file at the API's configured
+`NESTQUEST_DB_PATH` on the API host, which need not be anywhere near the Home
+Assistant config directory. To return to 0.6.0 you must restore a backup of
+that file taken before the upgrade; a plain downgrade is impossible once
+migrated.
+
+**API host (database):**
+
+1. Before upgrading, stop the NestQuest API service and back up the database
+   file at its configured `NESTQUEST_DB_PATH`, plus its `-wal` and `-shm`
+   sidecars (`<NESTQUEST_DB_PATH>-wal`, `<NESTQUEST_DB_PATH>-shm`) if present.
+   Only then deploy 0.7.0 and start the API service, which applies migration 8.
+2. To roll back: stop the API service, restore the backed-up database and
+   sidecars to `NESTQUEST_DB_PATH`, redeploy the API service at 0.6.0, and roll
+   back the Home Assistant integration to 0.6.0 (below). Then restart the API
+   service and Home Assistant.
+
+**Home Assistant integration — HACS installs** (integration component only;
+the database lives with the API, see above):
+
+1. To roll back: HACS > Integrations > NestQuest > Redownload > 0.6.0, then
+   restart Home Assistant.
+
+**Home Assistant integration — Manual installs** (integration component only;
+the database lives with the API, see above):
+
+1. To roll back: replace `custom_components/nestquest/` with the 0.6.0 tree,
+   then restart Home Assistant.
+
+**Repository operators:** git-revert the 0.7.0 release merge on `main`.
+
+## Version 0.6.0 — 2026-09-23
+
+### 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 bundles glyph data from the icon sets below. The curated names are listed in
+`tools/icons/curated-icons.json`; `tools/icons/generate.mjs` reads each glyph's SVG path
+data from the locally installed packages and generates it into both bundles
+(`admin/src/icons/registry.generated.ts` and `frontend/src/icons/registry.generated.ts`).
+Nothing is loaded from a CDN or fetched at runtime. The package versions used are recorded
+in the header of each generated file.

+# 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
+on port 8080 — so on that box set ``NESTQUEST_BIND_ADDRESS`` to its
+LAN address (``10.60.1.14``). Traefik only allows
+``/api/v1/panel`` from the Home Assistant host. The full deployment,
+restore and verification procedure is in ``deploy/RUNBOOK.md``.
+
+## 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.
