"""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
|
||||
module never reads a timezone database or config of its own.
