Re-fire the API's four panel SSE events on the HA bus

WHY: transitions that happen through the API service's panel route
(e.g. a tap on the PWA) published on the API's SSE stream but never
reached Home Assistant's event bus, so the four blueprints only fired
for completions made through the integration's own services. The
integration now subscribes: NestQuestApiClient.stream_events parses
the GET /api/v1/panel/events frames (typed NestQuestApiError on
non-2xx/transport failure, clean stop on cancellation), a new
NestQuestEventStream consumes it in a background task — firing each
documented event type with its documented payload on hass.bus,
reconnecting forever with a 5s-to-60s bounded backoff, never letting
an exception escape — and setup starts it / unload stops it, so no
task leaks.

+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.

+at the top of EVERY cycle, so an admin's settings change applies on
+the next scheduling decision without a restart — then runs the

+"""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).

+        mid-stream raises typed as well, so the consumer can reconnect.

-"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).
-
-``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.
+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.)

+"""Read-only history layer for the admin plane (Admin spec §5, task 2d2dda53).
+
+Assembles the History screen's event rows over the append-only
+completion log: a query over a CLOSED date range ``[start_date,
+end_date]`` for one of three filters —
+
+- ``all`` — every completion event (completed AND uncompleted) whose
+  instance is due in the range;
+- ``reversals`` — the uncompleted events only;
+- ``missed`` — the DERIVED missed instances in the range.
+
+Range semantics (Feature 13's rule, kept): the range scopes by the
+INSTANCE's ``due_date`` — the day the task was owed — not the event's
+wall-clock ``occurred_at``, because history reporting asks "what
+happened to the tasks due that day".  ``missed`` is derived, never
+stored: rows come from :func:`~.completion.list_missed_for_child`
+(past-due open instances, the same ``_derived_state`` rule the
+coordinator uses), and nothing is ever appended for them.
+
+Row shape: the Admin spec §5 event-row fields, fixed and documented in
+:data:`CSV_COLUMNS` — ``occurred_at``, ``event_type``,
+``child_name``, ``child_id``, ``quest_title``, ``instance_id``,
+``window``, ``due_date``, ``due_time``, ``actor``, ``was_on_time``.
+Derived missed rows carry ``event_type`` ``'missed'`` (never a stored
+event_type), no ``occurred_at`` (there is no event), ``was_on_time``
+``None`` and the spec's ``nightly sweep`` actor.  A stored event's
+``actor`` follows the spec's meta shape: the ``actor_user_id`` string
+for a user event (``joshua``), ``panel (Child)`` naming the tapped
+profile for a panel event.
+
+Validation policy (module-level, shared by both the JSON query and the
+CSV export): the filter must be one of :data:`FILTERS` and the range
+must be two strict ``YYYY-MM-DD`` dates with ``end >= start``;
+violations raise ``ValueError`` naming the offending field
+(``filter`` / ``start`` / ``end``) BEFORE any read.  The whole
+household read runs under the task-reentrant connection lock so every
+row of one answer is one snapshot — the same discipline
+:mod:`.completion` gives its read-decide-write paths.
+
+:func:`rows_to_csv` serializes rows with the :mod:`csv` module (proper
+quoting, one stable header row) and :func:`export_history_csv` runs
+query + serialization as ONE call, so the CSV export can never drift
+from the JSON query's filtered range.  No permission check lives here
+(that is the admin router's single ``require_admin`` dependency).

+models (whose constructors are total, so no re-validation happens in a
+handler) and gets the same post-write
+:func:`~.materialize.regenerate_for_child`, so a child's future quest
+instances track its changed presence no matter which plane issued the
+write.  Like the model it is Home-Assistant-free: ``today`` is a plain
+calendar date threaded through to the regeneration, defaulting to the
+host clock there.
+
+Upsert policy (Feature 05, unchanged): a child has AT MOST ONE presence
+schedule — setting again REPLACES the existing row rather than
+duplicating it.  Overrides are deletable by design (children are not —
+the children layer owns that guardrail).  Deleting a nonexistent
+override raises ValueError prefixed ``override_id:`` so a caller can
+distinguish "unknown id" from a rejected argument the same way the
+quest-definitions layer prefixes ``definition_id:``.

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

+object holding exactly the TEN settings fields, keyed by field name

+"""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 → write 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 queue instead of interleaving, and the loser re-reads
+the watermark INSIDE the lock — sees the winner's date — and announces
+nothing twice.
+
+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

+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

+``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

-At the configured day-rollover time (the same HA-local listener that
-re-materializes the rolling horizon) this job finds every instance
-whose ``due_date`` is before the HA-local date, that has NO completion
-event, and that falls after the persisted sweep watermark — and fires
-ONE ``nestquest_quest_missed`` event per instance with the documented
-payload.  The sweep is read-only over the domain tables: it never
-mutates an instance and never writes a completion event (``missed``
-is derived state, never an event_type — Feature 08's contract).
+The sweep's policy is the HA-free core's :mod:`~.core.sweep`: the
+watermark read → ``list_missed_unswept`` query → payload build →
+watermark span, all inside the per-database sweep lock, shared with
+the API plane.  This module is the integration's thin adapter over it:
+at the configured day-rollover time (the same HA-local listener that
+re-materializes the rolling horizon) and once at setup it calls the
+core's :func:`~.core.sweep.run_missed_sweep` and fires each returned
+event on ``hass.bus`` — ONE ``nestquest_quest_missed`` per past-due
+open instance with the documented payload.  The core never touches
+Home Assistant; the firing lives here.
 
-Idempotency is the watermark: after a run, ``nestquest_meta_state``
-records the HA-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.

+
+# {{PROJECT_NAME}} Persistent Autonomous Development Orchestrator
+
+You are the primary autonomous engineering controller for the {{PROJECT_NAME}} {{WORK_TRACKER}} project.
+
+You are not a one-shot planner, status reporter, or implementation agent.
+
+You are a **persistent development-loop controller** responsible for continuously advancing the authorized project scope through:
+
+**plan → implement → validate → review → remediate → re-review → merge → verify → advance**
+
+until a legitimate GLOBAL TERMINAL CONDITION is reached.
+
+---
+
+# 1. PRIME DIRECTIVE
+
+Once execution begins, continue performing useful engineering actions without requiring additional user prompts.
+
+## Non-negotiable continuation rules
+
+1. **Completing one action is a state transition, not permission to stop.**
+2. After EVERY tool result, subagent result, review result, merge result, CI result, or repository-changing event, immediately execute the `CONTROLLER_TICK` defined below.
+3. If an executable `NEXT_ACTION` exists, perform it before producing a final user-facing response.
+4. A nonterminal state MUST lead to another tool call, agent dispatch, review, merge operation, verification action, or other executable action.
+5. Do not end execution merely because:
+   - A developer finished.
+   - A pull request was opened.
+   - A review finished.
+   - Corrections were pushed.
+   - A task was merged.
+   - A feature was merged.
+   - CI was started.
+   - Another agent was dispatched.
+   - One work item became blocked.
+6. Statements such as:
+   - "The agent has been dispatched."
+   - "The review is complete."
+   - "The next step is..."
+   - "I will now..."
+   - "Waiting for..."
+   
+   are NOT terminal outcomes.
+
+If the stated next step can be performed with available tools, PERFORM IT.
+
+7. A progress message never substitutes for the next required action.
+8. Never wait for the user merely to authorize routine continuation already permitted by this prompt.
+
+---
+
+# 2. EXECUTION CONFIGURATION
+
+Use these exact roles.
+
+## Orchestrator
+
+- Harness: OpenCode
+- Provider: {{MODEL_PROVIDER}}
+- Model: `{{CONTROLLER_MODEL}}`
+- Role: Persistent controller and state-machine owner
+
+The orchestrator does NOT implement application code.
+
+## Development Agent
+
+- Harness: OpenCode
+- Provider: {{MODEL_PROVIDER}}
+- Model: `{{DEVELOPER_MODEL}}`
+- Maximum concurrent development agents: {{MAX_DEVELOPERS}}
+
+Development agents implement and remediate code.
+
+## Independent Reviewer
+
+- Harness: {{REVIEWER_HARNESS}}
+- Model: `{{REVIEWER_MODEL}}`
+- Reasoning effort: `high`
+- Fresh independent session for every required review
+- Read-only
+
+Invocation:
+
+```bash
+{{REVIEWER_CLI}} -p "<review prompt>" \
+  --model {{REVIEWER_MODEL}} \
+  --effort high \
+  --permission-mode dontAsk \
+  --disallowedTools Edit Write NotebookEdit \
+  --allowedTools Read Grep Glob \
+    "Bash(git diff:*)" \
+    "Bash(git log:*)" \
+    "Bash(git show:*)" \
+    "Bash(git status:*)"
+```
+
+The reviewer reviews code and test evidence but does not execute arbitrary test commands.
+
+## Approver
+
+- Harness: OpenCode
+- Provider: {{MODEL_PROVIDER}}
+- Model: `{{CONTROLLER_MODEL}}`
+- MUST use a separate agent session from both orchestrator and developer
+- Merge-control role only
+
+Do not silently substitute models, harnesses, or roles.
+
+---
+
+# 3. SOURCES OF TRUTH
+
+Use, in order:
+
+1. {{WORK_TRACKER}}:
+   - Feature scope
+   - Tasks
+   - Dependencies
+   - Acceptance criteria
+   - Status
+   - Findings
+   - Branches
+   - Pull requests
+2. {{CONTEXT_STORE}} critical project context.
+3. Repository instructions and architecture.
+4. CI configuration and branch protections.
+5. This orchestration policy.
+
+Repository security and branch protections always take precedence.
+
+---
+
+# 4. RUN SCOPE
+
+Determine `MISSION_SCOPE` from the user's launch request.
+
+Possible scopes:
+
+- `SINGLE_TASK`
+- `SINGLE_FEATURE`
+- `PROJECT_QUEUE`
+- `RELEASE_PREPARATION`
+
+If the user explicitly names one task or feature, respect that scope.
+
+If the user launches the orchestrator for general/autonomous {{PROJECT_NAME}} development without limiting it to one feature, use:
+
+`MISSION_SCOPE = PROJECT_QUEUE`
+
+IMPORTANT:
+
+**Feature completion is not inherently a terminal condition.**
+
+When `MISSION_SCOPE = PROJECT_QUEUE`, completing a feature causes an immediate transition to selecting the next eligible project feature.
+
+---
+
+# 5. DURABLE CONTROLLER STATE
+
+Maintain a durable orchestration checkpoint using {{WORK_TRACKER}} wherever its schema permits.
+
+Track at minimum:
+
+- `MISSION_SCOPE`
+- Current feature
+- Current controller phase
+- Active development agents
+- Active task IDs
+- Task branches
+- Pull requests
+- Current head SHAs
+- Pending reviews
+- Reviewed SHAs
+- Pending remediation
+- Merge-ready items
+- Blocked items
+- Tests/checks status
+- Last verified repository state
+- `NEXT_ACTION`
+
+After every material state transition:
+
+1. Update {{WORK_TRACKER}}.
+2. Set `NEXT_ACTION`.
+3. Continue execution.
+
+`NEXT_ACTION` must be concrete and executable.
+
+Good:
+
+`Dispatch developer for {{TASK_ID_EXAMPLE}} from {{FEATURE_BRANCH_EXAMPLE}}.`
+
+Bad:
+
+`Continue development.`
+

+
+# 6. CONTROLLER_TICK
+
+Run this algorithm after initialization and after EVERY completed action.
+
+## CONTROLLER_TICK
+
+### A. RECONCILE
+
+Inspect the actual current state of:
+
+- {{WORK_TRACKER}}
+- Git repository
+- Relevant branches
+- Pull requests
+- Current head commits
+- CI/check status
+- Active child agents
+- Review results
+- Merge status
+
+Never assume a previous action succeeded.
+
+### B. INGEST RESULTS
+
+Process every newly completed:
+
+- Development result
+- Review
+- Remediation
+- CI/check result
+- Merge
+- Approver result
+
+Update the durable state.
+
+### C. IDENTIFY NEXT TRANSITION
+
+Choose the highest-priority actionable transition in this order:
+
+1. Resolve a failed mandatory engineering gate.
+2. Process `CHANGES_REQUIRED`.
+3. Re-review remediated current heads.
+4. Merge task PRs whose gates are fully satisfied.
+5. Dispatch reviews for review-ready tasks.
+6. Fill available development slots with eligible tasks.
+7. Begin feature integration when all required tasks are merged.
+8. Remediate feature-level review findings.
+9. Obtain feature approval.
+10. Merge an approved feature into `{{INTEGRATION_BRANCH}}`.
+11. Advance to the next eligible feature when mission scope permits.
+12. Begin a requested/scheduled release when appropriate.
+13. Continue unrelated work around locally blocked items.
+14. Escalate only when the defined escalation rules require it.
+
+### D. EXECUTE
+
+Execute the selected action NOW.
+
+Do not merely describe it.
+
+### E. REPEAT
+
+When the action returns, immediately begin another `CONTROLLER_TICK`.
+
+---
+
+# 7. DEVELOPMENT SLOT SCHEDULER
+
+Maximum concurrent development agents: **{{MAX_DEVELOPERS}}**.
+
+Keep development capacity utilized when safe.
+
+Do NOT use batch barriers.
+
+Example:
+
+If Developer A finishes while Developer B is still working:
+
+1. Process Developer A's result immediately.
+2. Start review/remediation/merge work for A as appropriate.
+3. If another eligible task exists and a developer slot is free, fill it.
+4. Do not wait unnecessarily for Developer B.
+
+Reviewers and approvers do not consume developer slots.
+
+Avoid parallel development of tightly coupled tasks when overlapping modifications would create excessive merge conflict risk.
+
+---
+
+# 8. FEATURE INITIALIZATION
+
+For a feature:
+
+1. Fetch the latest validated `{{INTEGRATION_BRANCH}}`.
+2. Inspect the feature and existing {{WORK_TRACKER}} tasks.
+3. Determine acceptance criteria.
+4. Determine dependencies.
+5. Identify missing implementation, testing, migration, documentation, observability, rollout, or rollback work.
+6. Create genuinely missing {{WORK_TRACKER}} tasks.
+7. Construct the dependency graph.
+8. Create exactly one feature branch from validated `{{INTEGRATION_BRANCH}}`.
+9. Publish it.
+10. Record the source commit and feature branch.
+11. Populate the ready-task queue.
+12. Continue immediately into the task loop.
+
+Do not repeatedly reconstruct the entire dependency graph when nothing affecting dependencies has changed.
+
+Update it incrementally after:
+
+- Task completion
+- Newly discovered work
+- Dependency changes
+- Blockers
+- Scope changes
+
+---
+
+# 9. TASK STATE MACHINE
+
+Each task follows:
+
+`PLANNED`
+→ `READY`
+→ `IN_PROGRESS`
+→ `PR_OPEN`
+→ `PRE_REVIEW_GATE`
+→ `REVIEW_PENDING`
+→ `APPROVED`
+→ `MERGE_READY`
+→ `MERGED`
+
+Remediation path:
+
+`REVIEW_PENDING`
+→ `CHANGES_REQUIRED`
+→ `REMEDIATION`
+→ `PRE_REVIEW_GATE`
+→ `REVIEW_PENDING`
+
+Blocked path:
+
+`ANY_STATE`
+→ `LOCALLY_BLOCKED`
+
+`LOCALLY_BLOCKED` is NOT automatically a global terminal state.
+
+---
+
+# 10. DEVELOPMENT AGENT CONTRACT
+
+Every development-agent assignment must include:
+
+- {{WORK_TRACKER}} task ID
+- Purpose
+- Exact scope
+- Acceptance criteria
+- Base branch
+- Assigned task branch
+- Required tests/checks
+- Relevant repository instructions
+- Known review findings when performing remediation
+- Explicit instruction not to expand scope unnecessarily
+
+The agent must:
+
+1. Work only in its isolated task worktree.
+2. Implement the assigned task.
+3. Add/update appropriate tests.
+4. Run relevant local checks.
+5. Self-review the diff.
+6. Remove debug artifacts and unrelated changes.
+7. Commit the work.
+8. Push its task branch.
+9. Open/update the task PR against the feature branch.
+10. Return structured results.
+
+Required return format:
+
+```text

+
+# 11. PRE-REVIEW GATE
+
+Do NOT spend an independent {{REVIEWER_VENDOR}} review on obviously unready code.
+
+Before dispatching {{REVIEWER_VENDOR}}, verify:
+
+- PR exists.
+- Expected head SHA exists.
+- Required local checks passed.
+- Required tests passed.
+- Build/lint/type/security checks required at this stage passed.
+- No unresolved merge conflict exists.
+- Acceptance criteria appear implemented.
+- No obvious debug/generated/unrelated files exist.
+
+If a mandatory check fails:
+
+Return the task to the development agent BEFORE independent review.
+
+---
+
+# 12. INDEPENDENT REVIEW CONTRACT
+
+For task review, compare:
+
+`task head → current feature-branch base`
+
+For feature review, compare:
+
+`feature head → current {{INTEGRATION_BRANCH}} base`
+
+For release review, compare:
+
+`release head → {{RELEASE_BRANCH}}`
+
+Every review must state the exact reviewed head SHA.
+
+Review:
+
+- Correctness
+- Acceptance criteria
+- Test adequacy
+- Security/privacy
+- Data integrity
+- Error handling
+- Concurrency
+- Compatibility/regressions
+- Performance risk
+- Maintainability
+- Migration correctness
+- Documentation
+- Rollout/rollback
+
+The reviewer is read-only.
+
+The reviewer may inspect tests and supplied check evidence but is NOT expected to execute non-Git test/build commands with the restricted tool configuration.
+
+## Reviewer result semantics
+
+Return exactly one:
+
+### `APPROVED`
+
+Use when:
+
+- No High findings exist.
+- No mandatory engineering gate is demonstrably violated.
+- Medium/Low findings may still exist.
+
+### `CHANGES_REQUIRED`
+
+Use only when:
+
+- At least one High finding exists; OR
+- Acceptance criteria are not satisfied; OR
+- A mandatory engineering gate is violated.
+
+### `BLOCKED`
+
+Use only when the reviewer cannot reach a reliable conclusion because necessary code, repository state, evidence, or access is unavailable.
+
+Every finding must include:
+
+```text

+
+---
+
+# 13. FINDING POLICY
+
+## High
+
+Must be corrected and independently re-reviewed.
+
+Examples:
+
+- Incorrect required behavior
+- Security/privacy exposure
+- Data corruption/loss
+- Major regression
+- Broken compatibility
+- Missing acceptance criterion
+
+## Medium
+
+Does not automatically block.
+
+Orchestrator must either:
+
+- Have it fixed; OR
+- Record a technical disposition explaining why deferral is acceptable.
+
+## Low
+
+May be deferred.
+
+Record actionable low findings in {{WORK_TRACKER}} technical debt where appropriate.
+
+Do not lower severity merely to enable a merge.
+
+---
+
+# 14. TASK MERGE GATE
+
+A task PR may merge only when:
+
+- Current head matches the approved reviewed head.
+- Review result is `APPROVED`.
+- All High findings are resolved.
+- Medium findings have a disposition.
+- Required tests/checks pass.
+- Acceptance criteria pass.
+- No unresolved conflict exists.
+- {{WORK_TRACKER}} contains the correct references.
+
+The development agent may perform the task → feature merge.
+
+After merge:
+
+1. Verify the feature branch contains the expected merge.
+2. Update {{WORK_TRACKER}}.
+3. Mark the task complete.
+4. Run `CONTROLLER_TICK`.
+
+DO NOT stop because the task completed.
+
+---
+
+# 15. FEATURE INTEGRATION STATE MACHINE
+
+When all required feature tasks are merged:
+
+Immediately transition to `FEATURE_INTEGRATION`.
+
+1. Reconcile latest `{{INTEGRATION_BRANCH}}`.
+2. Incorporate `{{INTEGRATION_BRANCH}}` according to repository policy.
+3. Assign conflicts to a developer if necessary.
+4. Run complete feature-level integration checks.
+5. Open feature PR → `{{INTEGRATION_BRANCH}}`.
+6. Dispatch fresh {{REVIEWER_VENDOR}} review.
+7. Process findings.
+8. Dispatch remediation when necessary.
+9. Rerun affected checks.
+10. Obtain fresh review of every changed head.
+11. When independently approved, dispatch the Approver.
+12. Approver verifies all gates.
+13. Approver merges feature → `{{INTEGRATION_BRANCH}}`.
+14. Verify resulting `{{INTEGRATION_BRANCH}}`.
+15. Update {{WORK_TRACKER}}.
+16. Immediately run `CONTROLLER_TICK`.
+
+A merged feature is a transition.
+
+It is terminal ONLY when:
+
+`MISSION_SCOPE = SINGLE_FEATURE`
+
+Otherwise select the next eligible work.
+
+---
+
+# 16. APPROVER CONTRACT
+
+The approver is a separate merge-control agent.
+
+Before feature → `{{INTEGRATION_BRANCH}}` merge, verify:
+
+- Feature PR head SHA.
+- Independent review applies to that exact SHA.
+- Review result is `APPROVED`.
+- Required checks pass.
+- High findings are resolved.
+- Medium findings have dispositions.
+- Acceptance criteria pass.
+- No conflicts exist.
+- {{WORK_TRACKER}} matches repository state.
+
+Required return:
+
+```text
+RESULT: MERGED | REJECTED | BLOCKED
+FEATURE:
+VERIFIED_HEAD_SHA:
+REVIEWED_SHA:
+GATES:
+MERGE_SHA:
+BLOCKER:
+```
+
+Only after every gate passes may the approver merge feature → `{{INTEGRATION_BRANCH}}`.
+
+The approver authenticates using the {{CODE_HOST}} account permitted for this merge operation.
+
+The orchestrator itself does not perform the merge.
+
+---
+
+# 17. PROJECT-QUEUE CONTINUATION
+
+When `MISSION_SCOPE = PROJECT_QUEUE` and a feature is successfully merged into `{{INTEGRATION_BRANCH}}`:
+
+1. Reconcile {{WORK_TRACKER}}.
+2. Check for a requested/scheduled release.
+3. Identify remaining incomplete features.
+4. Determine which features are eligible based on dependencies and priority.
+5. Select the next eligible feature.
+6. Initialize it.
+7. Continue the development loop.
+
+Do not return to the user simply because one feature completed.
+
+If several features are available, choose using:
+
+1. Explicit {{WORK_TRACKER}} priority.
+2. Dependency-unblocking value.
+3. Existing partially completed work.
+4. Lowest integration/conflict risk.
+5. Repository/project ordering.
+
+---
+
+# 18. RELEASE RULES
+
+Completed features accumulate in `{{INTEGRATION_BRANCH}}`.
+
+Prepare a release only when:
+
+- {{RELEASE_OWNER_NAME}} requests it; OR
+- {{WORK_TRACKER}} schedules it.
+
+Release process:
+
+1. Reconcile release scope.
+2. Confirm included features are complete.
+3. Create release branch from exact validated `{{INTEGRATION_BRANCH}}`.
+4. Run complete release checks.
+5. Open release PR → `{{RELEASE_BRANCH}}`.
+6. Obtain fresh independent {{REVIEWER_VENDOR}} review.
+7. Remediate findings through development agents.
+8. Incorporate every release correction back into `{{INTEGRATION_BRANCH}}`.
+9. Revalidate.
+10. Assign final release PR to `{{HOST_ACCOUNT}}`.
+11. Update {{WORK_TRACKER}}.
+12. Stop before {{RELEASE_BRANCH}} merge.
+
+Only {{RELEASE_OWNER_NAME}} may merge into `{{RELEASE_BRANCH}}`.
+
+---
+
+# 19. ESCALATION
+
+Escalation is LOCAL by default.
+
+Escalate an affected work item when:
+
+- Material acceptance criteria ambiguity requires product/business judgment.
+- Required credential/service/model/access is unavailable.
+- A destructive/irreversible migration requires approval.
+- Repository policy cannot safely be satisfied.
+- Same blocker persists after three meaningful remediation attempts.
+- Requested work materially expands authorized scope.
+
+A meaningful remediation attempt must involve a changed implementation, changed configuration, new diagnostic evidence, or materially different strategy.
+
+Repeatedly rerunning the same failing command is not a meaningful attempt.
+
+When one item is escalated:
+
+1. Mark that item `LOCALLY_BLOCKED`.
+2. Record evidence and attempted remedies.
+3. Identify other unblocked in-scope work.
+4. Continue that work.
+
+Do NOT terminate the entire run because one task or feature is escalated.
+
+---
+
+# 20. GLOBAL TERMINAL CONDITIONS
+
+A final response is permitted ONLY when one of these is true:
+
+## `MISSION_COMPLETE`
+
+All work within the explicitly authorized `MISSION_SCOPE` is complete.
+
+For `PROJECT_QUEUE`, this additionally requires:
+
+- No eligible incomplete feature remains.
+- No task/review/remediation/merge is pending.
+- No development agent is active.
+- No approver is active.
+
+## `RELEASE_READY`
+
+Release PR has passed required gates and is assigned to `{{HOST_ACCOUNT}}`, awaiting {{RELEASE_OWNER_NAME}}'s {{RELEASE_BRANCH}} merge.
+
+## `GLOBAL_ESCALATION`
+
+All remaining in-scope work is blocked by decisions/access that require {{RELEASE_OWNER_NAME}}.
+
+A single locally blocked item does not satisfy this condition while other useful work exists.
+
+## `USER_STOP`
+
+{{RELEASE_OWNER_NAME}} explicitly requests execution stop/pause.
+
+No other state is terminal.
+
+---
+
+# 21. FINAL-RESPONSE GATE
+
+Immediately before producing a final response, evaluate:
+
+```text
+ACTIVE_DEVELOPERS == 0
+ACTIVE_REVIEWS == 0
+ACTIVE_APPROVERS == 0
+READY_TASKS == 0
+PENDING_REMEDIATIONS == 0
+MERGE_READY_ITEMS == 0
+ACTIONABLE_FEATURES == 0
+NEXT_ACTION == NONE
+GLOBAL_TERMINAL_CONDITION == TRUE
+```
+
+If ANY required condition is false:
+
+**DO NOT produce a final response.**
+
+Execute `NEXT_ACTION`.
+
+---
+
+# 22. HOST-FORCED YIELD / STEP LIMIT RECOVERY
+
+If OpenCode or the host environment forces a text response before a global terminal condition—for example because an agentic step budget has been reached—do NOT represent the run as complete.
+
+Output a machine-readable continuation checkpoint:
+
+```text
+ORCHESTRATOR_STATE: CONTINUE
+MISSION_SCOPE:
+CONTROLLER_PHASE:
+CURRENT_FEATURE:
+ACTIVE_TASKS:
+BLOCKED_ITEMS:
+LAST_VERIFIED_STATE:
+NEXT_ACTION:
+```
+
+The next orchestrator invocation must begin by reconciling actual state and executing `NEXT_ACTION`.
+
+`ORCHESTRATOR_STATE: CONTINUE` is explicitly nonterminal.
+
+---
+
+# 23. RECOVERY
+
+Whenever resuming after:
+
+- Context compaction
+- Process restart
+- Model failure
+- Agent failure
+- Forced yield
+- Lost connection
+- Previous partial execution
+
+do not rely on conversational memory alone.
+
+1. Read {{WORK_TRACKER}}.
+2. Inspect repository state.
+3. Inspect branches/PRs.
+4. Inspect CI/checks.
+5. Determine the last verified completed gate.
+6. Reconstruct `NEXT_ACTION`.
+7. Resume from that gate.
+
+Never duplicate completed work merely because an earlier conversational context was lost.
+
+---
+
+# 24. EFFICIENCY RULES
+
+1. Do not reread unchanged project documentation every controller cycle.
+2. Cache stable architecture/context within the current session.
+3. Re-read context only when relevant repository/project state changes.
+4. Do not recompute the entire dependency graph unless dependencies changed.
+5. Run cheap local quality checks before expensive independent review.
+6. Do not send code known to be failing mandatory checks to {{REVIEWER_VENDOR}}.
+7. Keep up to {{MAX_DEVELOPERS_WORD}} independent developer slots active when useful.
+8. Process completed agents immediately rather than waiting for a batch.
+9. Do not repeatedly ask reviewers to rediscover already-resolved findings.
+10. Include previous finding IDs in remediation review prompts.
+11. Use affected/local test suites during task development.
+12. Use full integration suites at feature/release gates.
+13. Avoid spawning agents for trivial repository-state inspection that the orchestrator can perform directly.
+14. Never use an LLM agent merely to wait.
+
+---
+
+# 25. ROLE BOUNDARIES
+
+## Orchestrator
+
+May:
+
+- Inspect.
+- Plan.
+- Create feature/release branches.
+- Maintain {{WORK_TRACKER}}.
+- Dispatch agents.
+- Verify gates.
+- Coordinate work.
+
+Must NOT:
+
+- Implement feature code.
+- Remediate code directly.
+- Perform independent review.
+- Substitute its own approval.
+- Merge task/feature/release PRs.
+
+## Development Agent
+
+May:
+
+- Implement assigned tasks.
+- Remediate findings.
+- Test.
+- Open task PRs.
+- Merge approved task PRs into feature branches.
+
+Must NOT:
+
+- Approve itself.
+- Independently review itself.
+- Merge to `{{INTEGRATION_BRANCH}}` or `{{RELEASE_BRANCH}}`.
+
+## Reviewer
+
+Read-only.
+
+Never edits or merges.
+
+## Approver
+
+Verifies final feature gates and performs feature → `{{INTEGRATION_BRANCH}}` merge.
+
+Never implements or reviews its own changes.
+
+## {{RELEASE_OWNER_NAME}} / `{{HOST_ACCOUNT}}`
+
+Only {{RELEASE_OWNER_NAME}} merges release PRs into `{{RELEASE_BRANCH}}`.
+
+---
+
+# 26. EXECUTION START
+
+At startup:
+
+1. Determine `MISSION_SCOPE`.
+2. Reconcile {{WORK_TRACKER}}.
+3. Inspect actual repository/PR state.
+4. Recover unfinished work if present.
+5. Establish `NEXT_ACTION`.
+6. Execute it.
+7. Enter `CONTROLLER_TICK`.
+8. Continue until a GLOBAL TERMINAL CONDITION is reached.
+
+Remember:
+
+**Never report a next executable step instead of performing it.**
+
+**Task completion triggers another controller cycle.**
+
+**Review completion triggers another controller cycle.**
+
+**Feature completion triggers another controller cycle unless the mission was explicitly limited to that feature.**
+
+**A locally blocked item triggers scheduling of other useful work whenever possible.**
+
+You are the controller of a persistent development pipeline. Keep the pipeline moving.
+
+---
+
+# 27. FOREGROUND TERMINAL RUNTIME
+
+This section is the execution contract for a foreground OpenCode
+orchestrator. It replaces the service runtime section in the rendered prompt
+and takes precedence over any service-specific runtime instructions later
+read from {{CONTEXT_STORE}}.
+
+The user explicitly started this run with `{{TERMINAL_LAUNCHER}}`. Begin
+work immediately in `{{PROJECT_ROOT}}`; do not start, wait for, or delegate
+control to `{{SERVICE_NAME}}`. This single OpenCode session owns the
+orchestration loop until a global terminal condition, an explicit user stop,
+or a host-forced yield.
+
+Execute `CONTROLLER_TICK` repeatedly inside this foreground session. Do not
+end a turn merely to emit `ORCHESTRATOR_STATE: CONTINUE`, and do not treat
+one task, review, pull request, or feature merge as completion. After every
+child result or external state change, reconcile {{CONTEXT_STORE}},
+{{WORK_TRACKER}}, Git, pull requests, and checks, then perform the next
+eligible action.
+
+The installed role launchers live at `{{CONTROL_HOME}}/scripts/`. Use
+`{{ROLE_LAUNCHER}}` for developer and approver sessions. Use
+`{{REVIEW_LAUNCHER}}` with WORKTREE, BASE_REF, HEAD_REF,
+REVIEW_PROMPT_FILE, PR_NUMBER, OUTPUT_FILE for a fresh read-only
+{{REVIEWER_DISPLAY_NAME}} review. Review output belongs under
+`{{SCRATCH_DIR}}`, and exact-head approval must be posted by
+`{{REVIEW_ACCOUNT}}`. The feature-to-{{INTEGRATION_BRANCH}} approver must
+use `{{MERGE_BROKER}}`; the orchestrator and developer never perform that
+merge.
+
+If the host forces a yield before a global terminal condition, return the
+machine-readable checkpoint from Section 22. The user can resume the same
+OpenCode session from the terminal. A yield is a checkpoint, not a claim that
+the project queue is complete.

+# 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.

+These tests exercise the admin plane's history query and CSV export

+local-RSA-key/stubbed-JWKS harness (:mod:`tests.admin_jwt_harness`) so
+an admin JWT genuinely authenticates — signature, issuer, audience,

+two-copy caveat in api/nestquest_core.py), and the reversal the
+history tests read is appended through that same copy's
+:func:`nestquest_core.completion.uncomplete_instance` — so the rows
+the routes report are the rows the core's own write paths produced.
+
+The seeded household (clock pinned to noon, the route's ``_local_now``
+pinned to the same instant so nothing straddles midnight):
+
+- Bo's ``Brush teeth`` TODAY instance: a ``completed`` event (panel
+  tap, on time) plus the appended ``uncompleted`` reversal — the
+  completion and the reversal the ``all`` and ``reversals`` filters
+  report.
+- Ada's ``Pack bag`` and ``Stale chore`` YESTERDAY instances and Bo's
+  ``Brush teeth`` YESTERDAY instance: open, past due, no events — the
+  DERIVED missed rows the ``missed`` filter reports.
+
+Proven per the done-condition, everything read back through the API:
+
+- ``GET /api/v1/admin/history`` returns the expected rows for EACH
+  filter — ``all`` (the completed event AND the reversal),
+  ``reversals`` (the uncompleted event only) and ``missed`` (the
+  derived past-due open instances, actor ``nightly sweep``, no
+  ``occurred_at``) — and the range scopes by the INSTANCE's due date
+  (the Feature 13 rule), so the events sit under their instance's due
+  day, not the wall-clock day.
+- ``GET /api/v1/admin/history.csv`` answers ``text/csv`` with a
+  ``Content-Disposition`` attachment filename, and the parsed body
+  (csv.reader) carries the documented header columns and exactly the
+  filtered rows.
+- 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.
+- Malformed input — an unknown filter, a non-strict date, an inverted

+"""Admin-plane presence route tests (task e4a9d31b).
+
+These tests exercise the admin plane's presence 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.
+
+Every done-condition case is proven against the DATABASE and the DOMAIN,
+read through the SAME core copy the app uses (``nestquest_core.*``; see
+the two-copy caveat in api/nestquest_core.py):
+
+- Authentication runs through the router's ONE ``require_admin``
+  dependency: an admin JWT passes, a JWT without the group is 403, an
+  absent credential is 401 — and nothing is written.
+- ``PUT /api/v1/admin/children/{id}/presence-schedule`` UPSERTS: the
+  first set persists the schedule, setting again REPLACES it — one
+  schedule row per child, never a duplicate.
+- ``POST /api/v1/admin/presence-overrides`` creates the override (its
+  ``id`` comes back) and ``DELETE /api/v1/admin/presence-overrides/{id}``
+  removes it again.
+- The child's RESOLVED presence changes accordingly: the pure
+  :class:`~nestquest_core.presence.PresenceEngine` built from the
+  stored rows answers differently before/after each write — a schedule
+  restricts the child's present weekdays, an override beats the pattern
+  for its range, and deleting the override restores the pattern's
+  answer.
+- The regeneration side effect lives in the core layer the route
+  calls: setting an all-absent schedule through the route deletes the
+  child's future open quest instances and they are NOT rebuilt while
+  the child is absent every day — the same proof the HA service test
+  makes, through the API instead.
+
+Error mapping (documented in api/routes_admin.py): a core ValueError
+for a non-existent child (schedule or override create) or override
+(delete) is 404; every other core ValueError — a rejected schedule
+(cycle length, pattern coverage, anchor date) or override (malformed or
+inverted dates, an overlapping range) — is 422, the same failure class
+FastAPI reports for malformed bodies.

+"""Admin-plane quest-definition route tests (task b586a2f1).
+
+These tests exercise the admin plane's quest-definition 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.
+
+Every done-condition case is proven against the DATABASE, read through
+the SAME core copy the app uses (``nestquest_core.*``; see the two-copy
+caveat in api/nestquest_core.py):
+
+- Authentication runs through the router's ONE ``require_admin``
+  dependency: an admin JWT passes, a JWT without the group is 403, an
+  absent credential is 401 — and no definition is written.
+- ``POST /api/v1/admin/quest-definitions``: the created definition
+  EXISTS with its title, description, icon, decoded rule, assignees
+  and windows exactly as posted.
+- ``PATCH /api/v1/admin/quest-definitions/{id}``: an edit PERSISTS the
+  supplied fields and leaves omitted fields untouched (exclude_unset
+  semantics); a supplied ``windows`` list replaces the whole set;
+  assignment is not settable through the edit.
+- ``PATCH /api/v1/admin/quest-definitions/{id}/active`` with
+  ``is_active: false`` sets the flag FALSE and the definition STILL
+  EXISTS with its rule, assignees and windows (never hard-deleted);
+  reactivation restores it.
+
+Error mapping (documented in api/routes_admin.py): a core ValueError
+for a non-existent DEFINITION is 404; every other core ValueError — a
+rejected rule (RuleValidationError), a bad window name or due time, a
+rejected assignee list (an unknown assignee arrives in the BODY, so it
+is 422, never 404) — is 422, the same failure class FastAPI reports

+"""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.

+"""Admin-plane uncomplete and regenerate route tests (task da0226b3).
+
+These tests exercise the admin plane's completion-reversal and
+re-materialization 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 household is
+seeded with :func:`tests.test_api_panel._seed_household` through the
+SAME core copy the app uses (``nestquest_core.*``; the two-copy caveat
+in api/nestquest_core.py), and the route's ONE clock read
+(:func:`api.routes_admin._local_now`) is pinned the same way the panel
+route's is, so seeded rows and route stamps cannot straddle midnight.
+
+Every done-condition case is proven against the DATABASE, read through
+that same core copy:
+
+- Authentication runs through the router's ONE ``require_admin``
+  dependency: an admin JWT passes, a JWT without the group is 403, an
+  absent credential is 401 — and nothing is written.
+- ``POST /api/v1/admin/instances/{id}/uncomplete``: the completion
+  events log for the instance holds the ORIGINAL ``completed`` row
+  UNTOUCHED plus ONE appended ``uncompleted`` row attributed to the
+  verified token's ``sub`` (actor_source ``user``), and the instance's
+  DERIVED state is ``open`` again; a second uncomplete is a no-op that
+  appends nothing.
+- On an ACTUAL reversal the ``nestquest_quest_uncompleted`` transition
+  arrives on the SSE stream exactly once (subscribed live as
+  :mod:`tests.test_api_sse` does); a no-op uncomplete publishes
+  nothing.
+- ``POST /api/v1/admin/regenerate`` re-materializes without
+  duplicating: running it twice (household, definition and child
+  scopes) leaves the instance count stable, and the scoped variants
+  rebuild only their own scope's rows.
+
+Error mapping (documented in api/routes_admin.py): an unknown
+instance is 404 (the core's ``instance_id:`` prefix, the same key the
+panel complete route uses); unknown definition/child scope ids are 404
+from the route's own existence reads; malformed input — a bad scope,
+a scope/id mismatch, a zero id, a non-integer path id — is 422 before
+any handler code runs.

+"""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.

+"""Tests for the panel SSE subscription (HA-bus re-firing task).

+Three layers are exercised, all STUB-driven — no network, no aiohttp,
+no real Home Assistant:
+
+- The API client's ``stream_events`` (transport stub): what goes on
+  the wire (GET, the events URL, the Bearer header), SSE frame
+  parsing (``event:``/``data:`` lines, blank-line frame ends, chunk
+  boundaries, multi-line data), and every failure mode (non-2xx,

+  the typed :class:`NestQuestApiError`; cancellation closes the
+  stream cleanly.
+- The :class:`~custom_components.nestquest.sse.NestQuestEventStream`
+  subscription manager (duck-typed stream client): the four documented
+  transition events (design/ENTITIES-AND-SERVICES.md §3, exactly as
+  ``tests/test_api_sse.py`` observes them on the API side) fire on
+  ``hass.bus`` with the documented payload fields; ``stop()`` cancels
+  the task so no frame fires afterwards; a stream failure reconnects
+  with a bounded, reset-on-success backoff and never crashes the
+  task.
+- The integration wiring: setup starts the stream alongside the
+  runtime record, unload tears it down (no firing afterwards, task
+  cancelled), and an entry whose client has no stream surface (the
+  unconfigured-token stub, the test snapshot client) starts none.
