The HA integration is now purely a client of the NestQuest API service
(Feature 18): the API owns the SQLite file, the migrations, and every
business rule, so keeping a second copy of that ownership inside the
integration meant two sources of truth for household state, dead
wiring (the startup backfill, the day-rollover materialization and
sweep listeners, the corrupt-DB handling, the admin-allowlist seeding)
and settings keys nothing consumes any more.
Removed the integration's re-export/DB shim modules (db, store,
migrations, schema, the five DAOs, completion, children,
quest_definitions, admin_allowlist, presence, presence_management,
materialize, recurrence, events, sweep); the bundled domain package at
custom_components/nestquest/core/ is untouched and remains the single
home of those engines. Setup now builds only the API client, the
snapshot coordinator, and the SSE subscription, registers the one
complete_quest proxy, and forwards the platforms. The options flow
keeps only the keys the client itself consumes (API base URL + panel
token, update interval, staleness, panel idle timeout); the horizon,
rollover, notification and admin-allowlist settings moved out with the
database (the API's settings store owns horizon/rollover, and the
automations take their behaviour from blueprint inputs). The
integration-plane tests now script the panel route's payloads and SSE
frames instead of seeding a local database; the core-plane tests keep
their coverage with imports pointed at core directly.
Review round 1 (Codex gpt-5.6-terra, LOW): the racing test completed
synchronously and proved nothing. The executor now gates task A's
INSERT — inside its open transaction, after its overlap probe — so
task B queues on the connection lock, re-runs the probe against A's
committed row, and is rejected; exactly one lands. Suite: 990 passed.
PresenceOverridesDao.create now refuses an override that overlaps any
existing override of the SAME child (inclusive boundaries): the check
runs inside the same transaction as the INSERT under the connection
lock, so a racing create cannot slip a conflict between check and
write — a deterministic race test proves exactly one of two concurrent
overlapping creates lands. The ValueError names the conflicting
override's id, its range, and its flag. Round-trip, per-child scope,
and remove-then-recreate tests added. Suite: 990 passed.
