WHY: The nightly missed-quest sweep only existed on the Home
Assistant plane (the rollover listener fired hass.bus), so the API
service - now the writer of record with its own settings store and
SSE stream - had no way to announce missed quests, and an admin
could not trigger a catch-up run after downtime.
- Extract the sweep policy (watermark read, list_missed_unswept
query, documented payload build, watermark write, per-database
lock) into the HA-free core (core/sweep.py), building each event
through the shared events payload builder so the shape cannot
drift; the integration's sweep.py becomes a thin shim that fires
the returned events on hass.bus, keeping its signature.
- Admin trigger POST /api/v1/admin/missed-sweep: ONE clock read,
ONE core call, each returned event published on the SSE stream
through the existing publish_quest_missed helper; returns the
fired count. Watermark makes a same-day rerun silent and a
post-downtime run sweep the accumulated window once.
- Daily scheduler (api/scheduler.py) wired in the lifespan: reads
day_rollover_time fresh each cycle, runs the sweep at the
rollover, publishes on the app publisher, backs off and logs on
failure, cancels cleanly on shutdown; injectable clock/sleep for
tests.
- Tests: route trigger over a live uvicorn server with a live SSE
stream (one transition per instance with documented fields,
same-day rerun silent, post-downtime catch-up once, non-admin
403 / absent 401) plus the scheduler rollover/cancellation test.
