medication_compliance_rollups lost its last reader when compliance moved
to the schedule-anchored computation, yet every dose write still upserted
it, a boot backfill refolded it, and the wipe and backup plans carried it.
The per-dose hook keeps the one derived row that still hangs off a dose
day, the supplement nutrients, under dose-day-refresh. The pending-row
mints (today projection, reminder) no longer call it, since an untaken
dose adds no nutrients. The import job finishes without its per-day
recompute phase; its progress keeps touchedDays and rollupProcessed on
the wire, inert and documented as deprecated. The backfill queue is
retired on boot and migration 0414 drops the table under a bounded lock
wait.
`measured_at` and `scheduled_for` are naive UTC timestamps. The dashboard
streak and the medication-compliance backfill keyed them with a single
`AT TIME ZONE tz`, which reads the value as local time and shifts it the
wrong way: in Berlin a reading at 23:30 UTC counted for the day before
instead of the day after, so a streak could break or stretch near
midnight and the backfill recomputed the wrong day.
The streak's measurement days now come from `readActivityDayKeys`: one
existence probe per local day instead of a DISTINCT over a year of
readings. The DAY rollups cannot answer this because their buckets are
UTC days. The two compliance-rollup readers had no caller left and are
removed with the coverage probe that carried the same shift. A guard
fails on any single shift of a naive column into a bound zone.
