+You are the NestQuest controller. Work in the NestQuest repository. Maestro is
+the source of truth for feature and task state; CTXD is the source of truth for
+project instructions. At the start of every invocation, read the current
+NestQuest context in CTXD, including OPENCODE-ORCHESTRATOR-PROMPT.MD, then
+reconcile it with Maestro, Git, pull requests, and checks before dispatching.
+Follow the review, identity, and branch rules in that prompt.
+If the CTXD project or prompt is unavailable, do not dispatch or merge work;
+report the missing source and end with ORCHESTRATOR_STATE: BLOCKED.
+
+One invocation is a controller tick, not an entire feature lifetime. Prefer a
+state-changing action over another identical status query. Never repeat an
+unchanged tool call three times. If work is asynchronous, wait or inspect a
+specific changed result. Do not claim that you are continuing while ending
+the turn without naming the next action.
+
+The NESTQUEST_CONTROL_HOME environment variable names the installed launchers
+(normally /home/overseer/.local/share/nestquest-controller).
+For implementation, run "$NESTQUEST_CONTROL_HOME/scripts/nq-agent" with role
+developer, a task worktree, title, and task prompt file. For independent
+review, run "$NESTQUEST_CONTROL_HOME/scripts/nq-review" with the worktree,
+feature base ref, exact head ref, review prompt file, PR number, and an output
+file under /tmp/opencode. It publishes an exact-head Gitea approval only after
+Claude approves. The developer may merge
+a task PR into its feature branch only after independent approval of the exact
+head and verification of every task gate. For feature-to-dev approval and
+merge, run "$NESTQUEST_CONTROL_HOME/scripts/nq-agent" with role approver in
+a separate session after the independent review. Save the Claude review output
+in a file under /tmp/opencode and give that file and its reviewed head to the
+approver. Never substitute a different model or reviewer silently.
+
+When a feature is integrated into dev, reconcile Maestro, then immediately
+select and dispatch the next eligible feature. Feature completion is a
+transition, not the end of the controller's job. A release awaiting Joshua's
+main merge does not prevent work on independent eligible features.
+
+End each invocation with exactly one final line using one of these values:
+
+ORCHESTRATOR_STATE: CONTINUE
+ORCHESTRATOR_STATE: QUIESCENT
+ORCHESTRATOR_STATE: BLOCKED
+
+Use CONTINUE when there is any eligible or in-flight work; include the feature,
+task, and next concrete action immediately above the final line. Use QUIESCENT
+only after verifying no eligible or in-flight work remains in Maestro and the
+repository. Use BLOCKED only when a specific decision or access is required;
+include evidence and the needed human action. If you cannot establish the
+state, use BLOCKED. Never emit a success claim based only on a child's summary.

+# NestQuest foreground orchestrator
+
+OpenCode 1.18.32 loads the named agents from `.opencode/agents/`. Their
+models match the current NestQuest CTXD prompt: DeepSeek V4.1 Flash for the
+foreground orchestrator and approver, and GLM 5.3 Flash for development.
+Run orchestration directly from a shell:
+
+```bash
+nq-orchestrate
+nq-orchestrate mission.md
+cat mission.md | nq-orchestrate -
+nq-orchestrate --print-prompt > nestquest-orchestrator.md
+```
+
+The launcher renders the project prompt with the foreground terminal runtime,
+stops the dormant legacy service, refuses immediately when another NestQuest
+TUI is open, and then replaces itself with OpenCode using
+`terminal-orchestrator`. There is no background polling process and no wait
+for a controller tick. Exit or interrupt the TUI to stop the foreground run;
+resume that OpenCode session when a host-forced yield needs continuation.
+
+`scripts/nq-agent` launches developer and approver sessions with fixed agent
+definitions and no `--auto` flag. Headless OpenCode runs use `--pure` so the
+global idle-notification plugin does not notify on every controller tick.
+The approver's shell permission permits only the installed
+`nq-approve-merge` broker for Gitea. That broker requires exact-head
+Claude approval evidence, an exact-head Gitea approval by `review_agent`,
+the `dev` target, a mergeable PR, and passing configured checks before it
+requests a squash merge with Gitea's atomic `head_commit_id` guard.
+`scripts/nq-review` launches the independent
+Claude review in a noninteractive read-only session in the task worktree,
+checks the head again afterward, saves
+the output under `/tmp/opencode`, and posts the Gitea approval.
+The approver verifies the reviewed head again before a merge.
+
+The terminal launcher uses a stable copy of this configuration and scripts
+at `/home/overseer/.local/share/nestquest-controller`; it does not depend on
+which task branch is checked out in the primary NestQuest directory. Install
+that copy, run `scripts/nq-controller --check`, and verify the OpenCode
+agents (terminal-orchestrator, developer, and approver)
+with `opencode debug agent <name>` while `OPENCODE_CONFIG_DIR` points at the
+installed `.opencode` directory. Install `scripts/nq-orchestrate` in
+`~/.local/bin/`. For the global slash command, also install
+`.opencode/agents/terminal-orchestrator.md` under
+`~/.config/opencode/agents/` and
+`deploy/opencode-global-commands/start-nestquest-development.md` under
+`~/.config/opencode/commands/`. The old `nestquest-controller.service` remains static and
+inactive only for migration safety; foreground launch stops it.
+
+Inside an already-open OpenCode TUI, `/start-development` (or the global
+`/start-nestquest-development`) switches to the same foreground
+`terminal-orchestrator` behavior immediately. The shell launcher is the
+preferred entry point when supplying a mission prompt file.
+
+`templates/ORCHESTRATOR-PROMPT.template.md` and
+`templates/nestquest.profile.json` make the current CTXD cycle prompt
+adaptable to another project. See `templates/README.md` before publishing a
+rendered prompt for a new project.
+
+The CTXD preflight reads the configured HTTP/MCP server's NestQuest prompt.
+It deliberately does not inspect `/home/overseer/.ctx/ctxd.db`, which belongs
+to a different local store and lacks this project.
+
+All four agent credentials are currently readable by the same Unix account.
+The Gitea review and merge gates enforce normal workflow sequencing, but
+they are not a hard isolation boundary against a process running as that
+account. Strong isolation requires separate OS identities and protected
+credentials for the controller, reviewer, and approver.
+
+The terminal runtime repeatedly executes CONTROLLER_TICK within the foreground
+session. Neither a feature merge nor a progress report ends the run while
+eligible work remains. A host-forced yield returns a continuation checkpoint
+that can be resumed in the same OpenCode session.
+
+Do not put tokens in this repository or in unit files. Existing OpenCode MCP
+connections supply CTXD and Maestro. Rotate those MCP tokens as a coordinated
+operation across every consumer before revoking the old values.

+1. **Install the integration and add the config entry.** Install
+   NestQuest via HACS or manually (see Installation above) and restart
+   Home Assistant. Then, in *Settings → Devices & Services*, click
+   **Add Integration**, search for **NestQuest**, and submit the flow —
+   it has no fields; it just creates the single config entry. Then open
+   the entry, click **Configure**, and fill the panel-plane API
+   connection in the options flow:
+
+   - **NestQuest API base URL** — the full `http://host:port` URL of
+     your NestQuest API service (default `http://127.0.0.1:8000`).
+   - **Panel service token** — the token the panel presents to the API
+     service as its Bearer credential. It may stay empty until you have
+     one; a pasted token must be unpadded.
+
+   The form's remaining fields (panel idle timeout, coordinator update
+   interval, last-good snapshot staleness) have defaults that serve the
+   panel and need no change here.
+
+2. **The panel dashboard appears automatically.** On setup the
+   integration registers one storage-mode Lovelace dashboard: a sidebar
+   entry titled **NestQuest** at the URL path `/nestquest`, whose stored
+   config is nothing but the **`custom:nestquest-party` strategy**
+   (`strategy: { type: custom:nestquest-party }`). The strategy
+   generates the views at render time from the household roster:
+
+   - **The Party** — the party-board view at `/nestquest/party`; the
+     dashboard root `/nestquest` shows it as the first view.
+   - one quest-log view per child at `/nestquest/<child-slug>`
+     ("Ada's Quest Log", …), in roster order.
+
+   Nothing is hand-configured: no YAML, no manual views, no
+   `child_order`, no `quest_log_path`/`board_path` — the board and the
+   quest logs compute their navigation paths from the dashboard's own
+   URL — and every generated view is already in **Panel** layout (see
+   the two constraints below). If the Lovelace surfaces are unavailable
+   (for example when Lovelace runs in YAML mode), setup logs a warning
+   and skips the registration; create the dashboard manually with the
+   same strategy as described in the manual alternative below.

    a new user for the wall device. Make it **non-admin**, and ensure it is

+   dock and paste the dashboard URL from step 2 — the dashboard root,
+   `/nestquest` (TouchHub loads that URL directly as the kiosk landing
+   page). Set TouchHub **Auto-Return** to a value GREATER than the
+   quest log's `idle_return_seconds` (default 40s) — recommend **60s or

-     board. Set `weather_entity` (optional; the dock falls back to
-     date/time), `quest_log_path: /nestquest/log` (the view the crest tap
-     navigates to), and `child_order: [slug1, slug2, slug3]` listing each
-     child's slug in display order.
-
-   - **View 2 path `log`** (URL `/nestquest/log`) — quest log
-     (`type: custom:nestquest-quest-log-card`): the per-child quest screen
-     the party board hops to. Set `board_path: /nestquest/board` (the
-     party-board view to return to), `weather_entity`,
-     `idle_return_seconds` (must be shorter than TouchHub Auto-Return),
-     `confirm_timeout_seconds`, and `complete_screen_seconds`. The quest
-     log reads the selected child's slug from the view's URL path, so the
-     board → log hop is a plain Lovelace navigation.
-
-    Each view's layout MUST be set to **Panel** (Edit Dashboard → pencil on the
-    view → View type: Panel). Home Assistant's default Masonry layout constrains
-    the 1080px-tall NestQuest card to a narrow column; Panel (single-card)
-    layout is what renders the card full-screen at 1920×1080.
-
-    The dashboard contains only the NestQuest panel card for each view —
-    no other cards, no admin controls.
-
-   The `quest_log_path` and `board_path` values must match the dashboard
-   slug and view paths above: `/<slug>/<view>`. If you chose `nestquest`
-   as the dashboard slug with view paths `board` and `log`, the card
-   configs are already correct. If you pick different names, substitute
-   your actual paths in **both** card configs — e.g. a dashboard slug
-   `chores` with view paths `main` and `history` needs
-   `quest_log_path: /chores/history` and `board_path: /chores/main`.
-   Navigation between the two views fails (the crest tap or back button
-   lands on a 404) if the card config paths do not match the dashboard
-   slug and view paths exactly.

 TouchHub loads the dashboard URL directly. The NestQuest cards are normal
 Lovelace cards, not an iframe, so no Home Assistant framing setting is
 needed.
 
+### The two constraints
+
+- **Panel layout.** Every view must be in **Panel** (single-card)
+  layout: Home Assistant's default Masonry layout constrains the
+  1080px-tall NestQuest card to a narrow column, while Panel renders the
+  card full-screen at 1920×1080. The zero-config path already satisfies
+  the requirement — the strategy generates every view as
+  `type: panel` — while the manual alternative below requires setting
+  the layout by hand on each view (Edit Dashboard → pencil on the view
+  → View type: Panel).
+
+- **TouchHub Auto-Return.** TouchHub's **Auto-Return** must be greater
+  than the quest log's `idle_return_seconds` (default 40s) — recommend
+  **60s or higher** — so the launcher does not reclaim the wall device
+  before the quest log's own idle return navigates back to the party
+  board.
+
+### Manual alternative: build the dashboard by hand
+
+If you prefer not to use the zero-config dashboard above — or its
+registration was skipped — configure a Lovelace dashboard whose **URL
+slug is `nestquest`** (Settings → Dashboards → Edit → URL slug)
+yourself. Two options, in decreasing order of convenience:
+
+- **Use the strategy.** Give the dashboard
+
+  ```yaml
+  strategy:
+    type: custom:nestquest-party
+  ```
+
+  and no views of your own — the strategy generates the party-board and
+  quest-log views (each already in Panel layout) from the household
+  roster at render time. Optional `url_path` and `weather_entity` keys
+  may sit beside `strategy:`.
+
+- **Build the two views by hand.** A functional panel needs **two**
+  views in that dashboard, each with its own card config from
+  `design/ENTITIES-AND-SERVICES.md` §4. Give the views these exact URL
+  paths (the path segment after the dashboard slug):
+
+  - **View 1 path `board`** (URL `/nestquest/board`) — party board
+    (`type: custom:nestquest-party-board-card`): the household quest
+    board. Set `weather_entity` (optional; the dock falls back to
+    date/time), `quest_log_path: /nestquest/log` (the view the crest tap
+    navigates to), and `child_order: [slug1, slug2, slug3]` listing each
+    child's slug in display order.
+
+  - **View 2 path `log`** (URL `/nestquest/log`) — quest log
+    (`type: custom:nestquest-quest-log-card`): the per-child quest screen
+    the party board hops to. Set `board_path: /nestquest/board` (the
+    party-board view to return to), `weather_entity`,
+    `idle_return_seconds` (must be shorter than TouchHub Auto-Return —
+    see the two constraints above), `confirm_timeout_seconds`, and
+    `complete_screen_seconds`. The quest log reads the selected child's
+    slug from the view's URL path, so the board → log hop is a plain
+    Lovelace navigation.
+
+  The dashboard contains only the NestQuest panel card for each view —
+  no other cards, no admin controls. Each view's layout MUST be set to
+  **Panel** — see the two constraints above for why; the strategy
+  generates it for you, hand-built views do not get it for free.
+
+  The `quest_log_path` and `board_path` values must match the dashboard
+  slug and view paths above: `/<slug>/<view>`. If you chose `nestquest`
+  as the dashboard slug with view paths `board` and `log`, the card
+  configs are already correct. If you pick different names, substitute
+  your actual paths in **both** card configs — e.g. a dashboard slug
+  `chores` with view paths `main` and `history` needs
+  `quest_log_path: /chores/history` and `board_path: /chores/main`.
+  Navigation between the two views fails (the crest tap or back button
+  lands on a 404) if the card config paths do not match the dashboard
+  slug and view paths exactly.

 # 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,

+- **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`.

+The snapshot route (task ef3f4877) is the admin-plane twin of the
+panel's ``GET /api/v1/panel/snapshot`` for the admin PWA's Today tab —
+the PWA is internet-facing and never holds the panel service token
+(D-012), so it reads the same snapshot here:
+
+- ``GET /snapshot`` threads ONE clock read (:func:`_local_now`) into
+  :func:`nestquest_core.snapshot.build_snapshot` and shapes each
+  child's instances through
+  :func:`nestquest_core.snapshot.instance_payload` with
+  ``include_missed=True`` — admin payloads KEEP missed instances with
+  their ``missed`` state (D-009), where the panel omits them.  The
+  body is the panel's documented shape (``today_iso``, ``cycle_day``,
+  ``children`` with the per-child presence, rollup counts and
+  ``instances``); the builder, the state derivation and the shaping
+  all live in the core.
+
+The settings routes (task 2b3de7e5) follow the same pattern over
+:mod:`nestquest_core.settings_store` — the API's OWN durable settings
+store.  The API now OWNS settings in the database (a validated JSON

+integration's Home-Assistant config-entry options remain a temporary,
+SEPARATE source until Feature 18 wires the client to the API — the two
+are deliberately not unified here:
+
+- ``GET /settings`` returns the current effective settings: all ten
+  documented fields (the rolling horizon, the day rollover time, the
+  notify target, the three notification times and the four enable
+  toggles) — the defaults on a fresh database.
+- ``PATCH /settings`` updates ONLY the supplied fields: the body is a
+  JSON object of settings field names to new values, passed STRAIGHT
+  to :func:`nestquest_core.settings_store.update_settings` — the
+  unknown-field rejection, the per-field validation (the core settings
+  validators: a positive int, strict ``HH:MM`` strings, real booleans)
+  and the validate-everything-before-write atomicity all live in the
+  core, so a rejected update never changes the stored settings.  A
+  JSON ``null`` value resets its field to the default (the settings
+  module's uniform None-as-absent rule).  The response is the updated
+  effective settings, the same shape ``GET`` returns.
+

+:mod:`nestquest_core.sweep` — the HA-free sweep policy the
+integration's rollover listener shares:

+"""Daily missed-sweep background scheduler for the API service.
+
+The API service has no Home Assistant, so nobody re-fires the
+integration's day-rollover listener for it: this module owns the API
+plane's own background job.  One :class:`MissedSweepScheduler` per app
+(installed on ``app.state`` by the lifespan) sleeps until the
+configured ``day_rollover_time`` — read fresh from the settings store
+at the top of EVERY cycle, so an admin's settings change applies on
+the next scheduling decision without a restart — then runs the
+HA-free core's :func:`nestquest_core.sweep.run_missed_sweep` for the
+API host's local date and publishes each returned
+``nestquest_quest_missed`` event on the app's ONE transition publisher
+(the same SSE stream every route publishes through).
+
+All sweep policy lives in the core (the watermark, the
+``[watermark, today)`` window, the no-completion-event rule): this
+scheduler only decides WHEN.  A same-night rerun — e.g. two workers,
+or a settings change moving the rollover past itself — fires nothing:
+the core's watermark makes the run an empty no-op.
+
+Testability: ``clock`` (an aware-now callable) and ``sleep`` (an
+awaitable delay) are injectable, so tests pin the time, fast-forward
+through the wait, and observe the computed delays without waiting a
+real day.  Cancellation: :meth:`stop` cancels the loop task and waits
+for it, so the lifespan's shutdown is clean and a mid-run sweep is
+interrupted before the connection closes.  A failed iteration (a
+database hiccup, a rejected setting) is logged and retried after a
+fixed backoff rather than silently killing the job.

+"""Panel-plane API client for the NestQuest integration (Feature 18).
+
+The integration talks to the NestQuest API service (Feature 16) over
+HTTP instead of reading the database: this module is the ONE place that
+speaks the API's panel plane — ``GET /api/v1/panel/snapshot`` (today's
+household snapshot) and ``POST /api/v1/panel/instances/{id}/complete``
+(completion as the tapped child profile) — authenticated with the
+static panel service token as a Bearer credential on every request.
+
+Transport-injected by construction: the constructor takes the base URL,
+the panel token, and the HTTP session to use.  The session speaks the
+aiohttp ``ClientSession`` surface (``request(method, url, headers=...,
+json=...)`` returning an async context manager whose response carries
+``status`` and ``await text()``), so tests stub the transport with NO
+network and NO aiohttp installed; production builds the client through
+:func:`client_from_entry`, which hands in Home Assistant's shared
+aiohttp session (``homeassistant.helpers.aiohttp_client
+.async_get_clientsession``).  The module itself imports NEITHER
+homeassistant NOR aiohttp at runtime (aiohttp appears only behind
+``TYPE_CHECKING`` for annotations), so the client is usable anywhere —
+the HA coupling lives in the one production factory.
+
+Every failure is typed: a transport failure (connection refused, DNS
+failure, timeout — the exchange never produced a response) and every
+non-2xx HTTP response raise :class:`NestQuestApiError`.  The error
+carries the HTTP status where there is one (so 401 and 404 are
+distinguishable at the call site) and ``None`` when there is not; the
+original transport error is chained as ``__cause__`` — nothing is
+swallowed.  There are NO retries and the client logs nothing: refresh
+cadence is the coordinator's concern (the next task), and the panel
+token is a secret that must never reach a log line or an error
+message — the error texts name the method, path, and status only.
+
+The panel plane's SSE event stream (``GET /api/v1/panel/events``) is
+exposed by :meth:`NestQuestApiClient.stream_events` — an async
+generator yielding ``(event_type, payload)`` per Server-Sent Events
+frame (``event: <type>`` / ``data: <json>`` lines separated by a blank
+line).  Opening the stream gets the same one-timeout, typed-error
+contract as every other call; reading it has NO body-wide timeout (a
+healthy stream is long-lived — the subscription manager owns
+reconnection and backoff).

-"Today" and "now" are HA-local (``hass.config.time_zone``), never the
-host clock and never UTC, matching the materialization and completion
-layers.
+Since Feature 18 the snapshot no longer comes from the local database:
+the coordinator polls the NestQuest API service's panel plane —
+``GET /api/v1/panel/snapshot`` through
+:class:`~.api_client.NestQuestApiClient` on its update interval — and
+RECONSTRUCTS the same core dataclasses the local builder produced
+(:class:`~.core.snapshot.NestQuestSnapshot`,
+:class:`~.core.snapshot.ChildDaySnapshot`,
+:class:`~.core.snapshot.QuestInstanceView`).  ``sensor.py`` and
+``binary_sensor.py`` read ``coordinator.data`` and
+:func:`~.core.snapshot.instance_payload` exactly as before, so every
+entity_id and attribute payload shape is unchanged: the panel cards and
+the four blueprints keep working untouched.
 
-The snapshot assembly itself lives in the Home-Assistant-free
-:mod:`custom_components.nestquest.core.snapshot` module
-(:func:`~core.snapshot.build_snapshot`); this coordinator is now a thin
-HA wrapper that resolves the local timezone and reads the settings handed
-into its constructor, then delegates to that builder, passing the SAME
-HA-local ``now`` it resolved in one clock read.  The API service's panel
-snapshot route shares the same builder, so both consumers render ONE
-snapshot shape.
+One loss is deliberate and documented (D-009 revisited): the panel
+payload OMITS missed instances, so a snapshot rebuilt from the API can
+no longer carry them — ``admin_instances`` (``include_missed=True``)
+now equals ``instances`` (they can hold only open and completed rows).
+The admin surface for missed quests is the PWA, which reads the API
+service directly; the integration's entities never needed missed rows
+for their states or counts (the counts arrive precomputed).
 
-Presence is resolved through the SAME engine the materializer uses
-(:class:`~.presence.PresenceEngine`): schedules and overrides are read
-with the public DAO methods and the engine's anchor-date arithmetic
-answers ``is this child at this house today`` (D-004 — never ISO week
-parity).
+Failure handling: constructing the client fails fast (ValueError) when
+the entry has no panel token configured, and a fetch failure raises the
+typed :class:`~.api_client.NestQuestApiError`.  Neither crashes
+integration setup: the constructor logs a clear message and hands back
+a client-shaped stub whose refresh raises the same typed error, and
+``_async_update_data`` converts every typed error into
+:class:`~homeassistant.helpers.update_coordinator.UpdateFailed` — the
+exception a HA ``DataUpdateCoordinator`` records as a failed pass
+(``last_update_success = False``, ``data = None``), so the entities
+come up unavailable.  The typed error is never swallowed silently: it
+is logged with its message and chained into the UpdateFailed.  (The
+conversion matters at setup: HA's real
+``async_config_entry_first_refresh`` wraps any failed pass in
+``ConfigEntryNotReady``, so a setup that keys on the original
+exception type would never match it.)
 
-``cycle_day`` reports where today falls in the custody cycle of the
-first active child (display order) that HAS a schedule — 1-based day
-``N`` of ``cycle_length_weeks * 7``, computed from that schedule's
-anchor date.  ``0`` means no active child has a schedule at all, so
-the admin header degrades to a harmless zero instead of guessing.
+Last-good cache and staleness: every successful pass refreshes a cache
+of the rebuilt snapshot stamped with the :func:`time.monotonic`
+instant of the success.  A typed failure is checked against that stamp
+BEFORE the pass is declared failed: within the configured staleness
+threshold (``CONF_SNAPSHOT_STALENESS``, seconds, default three update
+intervals) the pass SUCCEEDS with the cached snapshot — the panel
+keeps rendering last-good data and the entities stay available — and
+the outage is logged as a warning.  Entities go unavailable only once
+the cache is older than the threshold (or before the first success);
+a later successful fetch refreshes the cache and the entities recover
+on their own, without a config-entry reload.

+source: a JSON document kept in the EXISTING ``nestquest_meta_state``

+key :data:`SETTINGS_META_KEY` — no schema change, no new table —
+validated through the SAME field table the settings object is built

+- ``morning_summary_enabled``, ``afternoon_reminder_enabled``,
+  ``end_of_day_report_enabled``, ``celebration_enabled`` — real
+  booleans.
+
+Only values whose core validators ACCEPTED are ever written, so a

+"""The nightly missed-quest sweep, Home-Assistant-free (Feature 11).
+
+This is the HA-free heart of the missed sweep, shared by the two
+planes: the Home Assistant integration's :mod:`~..sweep` shim (which
+fires the returned events on ``hass.bus``) and the API service (which
+publishes them on the SSE stream and can also trigger the run on
+demand).  It owns the ONE sweep policy:
+
+At the configured day-rollover time (or on an explicit trigger) this
+job finds every instance whose ``due_date`` is before the
+household-local date, that has NO completion event, and that falls
+after the persisted sweep watermark — and RETURNS one
+``nestquest_quest_missed`` event per instance with the documented
+payload.  Like every core module, it never touches the Home Assistant
+event bus and never mutates an instance: ``missed`` is derived state,
+never an event_type (Feature 08's contract), so the sweep is read-only
+over the domain tables.
+
+Idempotency is the watermark: after a run, ``nestquest_meta_state``
+records the household-local date the sweep ran, and the next run only
+sweeps instances due in ``[watermark, today)``.  A second run the same
+night therefore fires nothing new, and a run after days of downtime
+sweeps exactly the accumulated window once — no per-instance journal,
+no re-announcing old misses.  An instance swept as missed that is
+later completed simply gains its completion event; history keeps both
+rows (append-only), and the sweep's later runs skip it via the
+no-completion-event rule.
+
+The whole watermark read → query → build span runs inside the
+per-database sweep lock (one lock per connection wrapper and running
+loop, the settings store's pattern): an overlapping startup sweep and
+a rollover sweep of the SAME process queue instead of interleaving.
+The announce decision itself is the DATABASE-level claim
+(:meth:`MetaStateDao.claim`), so two PROCESSES sharing one SQLite file
+(the integration's rollover sweep and the API service's scheduler)
+cannot both announce the same missed batch either: both may read the
+old watermark and build the events, but the single conditional upsert
+lets exactly one of them win the claim — the loser returns [] and
+announces nothing.
+
+The caller supplies ``today`` as a plain :class:`datetime.date`: the
+household-local calendar date, read from ``hass.config.time_zone`` by
+the integration or from the API host's local clock by the API.  This
+module never reads a timezone database or config of its own.

+"""HA-bus subscription over the API service's panel SSE stream.
+
+The NestQuest API service (Feature 16) publishes every quest
+transition on ``GET /api/v1/panel/events`` as Server-Sent Events
+frames.  This module is the integration-side subscriber: ONE
+background task consumes :meth:`~.api_client.NestQuestApiClient
+.stream_events` and re-fires each frame on ``hass.bus`` with the SAME
+event type and payload fields the local transition path
+(:mod:`~.events`) emits — ``nestquest_quest_completed``,
+``nestquest_quest_uncompleted``, ``nestquest_quest_missed`` and
+``nestquest_child_day_complete`` — so the four blueprints fire
+identically whether a completion happens through the integration's own
+service or through the API service's panel route.
+
+Failure handling: a failed stream (API down, network blip, non-2xx, a
+dropped connection) is retried FOREVER with a bounded exponential
+backoff — :data:`RECONNECT_MIN_SECONDS` after the first failure,
+doubling up to :data:`RECONNECT_MAX_SECONDS` — so a long API outage
+neither pins the event loop nor spams the log, and a frame received on
+a healthy stream resets the backoff.  Nothing escapes the task: every
+failure is logged with its reason and the loop reconnects; a
+:class:`asyncio.CancelledError` (from :meth:`stop` or integration
+unload) is the only thing that ends it, and it stops cleanly — no
+frame fires after :meth:`stop` returns and the response is closed.

+# 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.

+# Reusing the development cycle prompt
+
+`ORCHESTRATOR-PROMPT.template.md` is the current NestQuest controller
+prompt with project-specific names, models, branches, identities, and launcher
+paths replaced by placeholders. `nestquest.profile.json` is the working
+example. Render a concrete prompt with:
+
+```bash
+scripts/render-cycle-prompt templates/nestquest.profile.json --output /tmp/opencode/nestquest-prompt.md
+```
+
+For another project, copy the profile and set its project name, tracker,
+context store, models, branch names, release owner, example IDs, review
+account, and installed launcher paths. Review the rendered result section by
+section, especially task/feature semantics, release rules, permissions,
+review gates, and the host runtime section. The template assumes an OpenCode
+controller, a feature/task tracker, a versioned context store, a code host,
+and a separate reviewer and approver. Adapt those sections when the project's
+systems differ. Section 27 is a single-session foreground loop suitable for
+`opencode --agent ... --prompt ...`; the reusable prompt has no service
+runtime.
+
+For NestQuest, `nq-orchestrate --print-prompt` emits the fully rendered
+foreground prompt without starting OpenCode. `nq-orchestrate [mission.md]`
+renders that same prompt, appends the optional mission, and supplies it to the
+foreground orchestrator agent.
+
+Publish the reviewed rendered prompt into that project's context store with
+its version check.
+Give the project its own agent definitions, broker, profile, and terminal
+launcher. The template itself does not start an orchestrator or register
+another project.

+# prefers, and a dev dependency here), decode HTML entities, NFKD again,
+# lowercase, drop quotes, fold runs of non-[a-z0-9-] to one dash, collapse
+# and strip dashes, then map dashes to the requested separator — and was
+# verified byte-for-byte against real python-slugify across Latin, Cyrillic,
+# CJK and Greek household-name shapes.  Transliteration is the point: HA
+# derives the per-child entity ids from a name like "京子" as
+# "nestquest_jing_zi_…", so the roster's slugs must transliterate too,
+# never dropping characters into "unknown".  Deliberately NOT truncating:

+"""Admin-plane settings route tests (task 2b3de7e5).
+
+These tests exercise the admin plane's settings read and update routes
+against the ASGI app with httpx, reusing the shared local-RSA-key/
+stubbed-JWKS harness (:mod:`tests.admin_jwt_harness`) so an admin JWT
+genuinely authenticates — signature, issuer, audience, expiry and the
+nestquest-admins group — with NO network access.  The stored settings
+document is read back through the SAME core copy the app uses
+(``nestquest_core.*``; see the two-copy caveat in api/nestquest_core.py)
+via its :class:`nestquest_core.dao_meta.MetaStateDao`, so persistence is
+proven against the DATABASE the routes wrote, not a parallel copy.
+
+Proven per the done-condition, everything read back through the API:
+
+- ``GET /api/v1/admin/settings`` returns the current effective settings
+  — the ten documented fields at their defaults on a fresh database.
+- ``PATCH /api/v1/admin/settings`` PERSISTS the supplied fields and the
+  NEXT read reflects them; a later partial update merges onto the
+  current effective settings (omitted fields keep their stored value),
+  and the document is stored under the well-known ``nestquest_meta_state``
+  key.
+- An invalid value (a non-positive or boolean horizon, a non-strict
+  time, a non-bool toggle, a non-string target) is rejected with 422
+  naming the field, and the stored settings are UNCHANGED — the next
+  read still shows the previous value.  An unknown field is rejected
+  the same way, also when mixed with a valid field (validate
+  everything before writing).
+- A corrupt stored document (invalid JSON, a non-object, an invalid
+  field value) does not crash the service: the read falls back to the
+  defaults, per field where possible.
+- Authentication runs through the router's ONE ``require_admin``
+  dependency: a non-admin JWT is 403 and an absent credential is 401
+  on both routes — and no refused patch writes anything.

+  ``cycle_day`` and, per child, the presence fields, the rollup counts
+  and ``instances`` in the core ``instance_payload`` shape.
+- A MISSED instance is KEPT in the admin payload (D-009) and still
+  OMITTED from the panel payload.  The core builder lists only
+  instances due on ``now.date()``, and ``derive_state`` calls an
+  instance missed only when its due date is BEFORE that day — so a
+  real snapshot never carries a missed view.  The test therefore
+  wraps the real builder to add the seeded past-due instance as a
+  view whose state the core's own ``derive_state`` computes
+  (``missed``), and reads it through both routes.
+- Auth runs through the router's ONE ``require_admin`` dependency: no
+  credential is 401, the panel service token is refused outright
+  (403, the credential-type detail), and a non-admin JWT is 403.
+- The handler performs exactly ONE clock read per request.

+"""Admin-plane missed-sweep trigger tests (task 058c7b69).
+
+These tests exercise ``POST /api/v1/admin/missed-sweep`` — the admin
+plane's trigger for the nightly missed-quest sweep — against a REAL
+server (uvicorn on an ephemeral port, the SSE tests' documented
+approach: httpx's ASGI transport buffers whole bodies, so a live
+stream needs a live server), plus the API service's daily scheduler:
+
+- The trigger requires the router's ONE ``require_admin`` check: a
+  non-admin JWT is 403 and an absent credential is 401, and neither
+  refusal runs the sweep.
+- Seeded past-due open instances: ONE ``nestquest_quest_missed``
+  transition per instance arrives on the LIVE SSE stream with the
+  documented payload fields (child_id, child_name, instance_id,
+  quest_title, window, due_date, due_time, occurred_at — §3), while
+  the seeded TODAY-due instance publishes nothing (the sweep's rule
+  is ``due_date`` strictly before ``today``).
+- A same-day rerun publishes nothing (the core watermark).
+- A run after downtime (``today`` advanced two days) publishes the
+  accumulated window once — the instance due on day one fires on the
+  catch-up run — and a further rerun is silent again.
+- Publishing is the api/scheduler.py shape — the sweep-BUILT
+  ``(event_type, payload)`` pairs go straight to the publisher, no
+  per-event re-fetch: all events of one run share the run's ONE
+  ``occurred_at`` stamp, and a deterministic concurrent-deletion case
+  (the sweep is wrapped to delete one swept instance after it built
+  its events and committed its watermark) still answers 200 and
+  streams every built event — a re-fetch there would 500 and lose the
+  missed event forever.
+- The daily scheduler (:class:`api.scheduler.MissedSweepScheduler`)
+  computes the delay to the configured ``day_rollover_time``, runs the
+  sweep when the (injectable) clock reaches it, publishes the built
+  events on its publisher, advances to the NEXT day's rollover, and
+  cancels cleanly.
+
+The household is seeded through the SAME core copy the app uses (the
+``nestquest_core.*`` package registered by ``api/nestquest_core.py``;
+see the two-copy caveat there) and the sweep's watermark is read back
+through the same copy's :class:`~nestquest_core.dao_meta.MetaStateDao`
+— on the SERVER's event loop for the uvicorn-hosted app (the database
+belongs to that thread's loop, so assertions schedule there), on the
+test's own loop for the scheduler test's standalone database.

+"""The ``nestquest.complete_quest`` proxy to the API client (Feature 18).
+
+The service is a thin proxy: a panel tap must reach the API's panel
+complete route through the entry's ONE shared API client (the same
+instance the coordinator polls and the SSE subscription reads), with
+exactly the payload contract the panel cards send (``instance_id``,
+``actor=panel``, ``actor_child_id``).  The service performs NO local
+completion and fires NO local bus event — the API service emits the
+transition on its SSE stream and the integration's subscription
+re-fires it (firing it locally too would double-fire) — and it
+refreshes the coordinator after a successful call so the sensors
+reflect the completion immediately.  Every failure (a typed
+:class:`NestQuestApiError`, an unconfigured client, a non-panel actor)
+surfaces as a :class:`HomeAssistantError`, token-free.
+
+The scripted clients here stand in for the API service: recording and

+"""Cross-process safety of the missed-sweep watermark claim.

+- :meth:`MetaStateDao.claim` is the atomic, database-level primitive:

+- :func:`run_missed_sweep` gates the announcement on that claim: two
+  independent ``NestQuestDatabase`` wrappers (two processes' shape)
+  racing one seeded database yields exactly one announcer.
+- The documented sweep semantics are unchanged: a same-night rerun
+  announces nothing, and a run after days of downtime announces the
+  accumulated ``[watermark, today)`` window exactly once.

+Everything here runs against the bundled HA-free core copy
