+"""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).

-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.

+"""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.

-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 core's 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
-fires nothing new, and a run after days of downtime sweeps exactly the
-accumulated window once.  An instance swept as missed that is later
-completed simply gains its completion event; the sweep is read-only
-over the domain tables (``missed`` is derived state, never an
-event_type — Feature 08's contract).

+"""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,
+  connection failure, mid-stream drop, malformed frame) surfacing as
+  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.
