The 36-hour grace window was a module-local constant inside
reminder-worker.ts while the admin route and the CLI both defaulted
to undefined. Lift the constant onto the helper module so the worker,
the admin route, and the CLI all import one source of truth. The
worker continues to pass the constant through to the helper; the
admin route and the CLI keep their existing default-undefined
behaviour (drain everything the operator points at) so a one-shot
pass still collapses every row regardless of recency.
Idempotent maintenance tool that collapses pre-Option-A per-sample
APPLE_HEALTH cumulative rows (steps, active energy, flights climbed,
walking + running distance, time in daylight) into one row per day
per type, keyed by the locked dailyStatsExternalId shape. Per
user × type × calendar-day (anchored to User.timezone): SUM the values,
UPSERT a daily row at canonical midday-local (matching the Withings
activity-sync convention), DELETE the per-sample rows.
Three entry points share src/lib/measurements/drain-per-sample-cumulative.ts:
- Library helper for unit + integration tests
- CLI at scripts/drain-per-sample-cumulative.ts with --user / --all
+ --confirm flags (default dry-run)
- Admin endpoint POST /api/admin/drain-per-sample-cumulative gated
by requireAdmin() with dryRun defaulting to true
Operator runs the drain once after the iOS TestFlight build adopts
HealthKitStatisticsService.swift. Re-running on a fully-collapsed
account reports zero buckets touched.
Tests cover bucketing semantics, the canonical-timestamp math across
DST + half-hour zones, idempotent re-runs, dry-run preview, spot-metric
exclusion, and already-collapsed-row skip via real-Postgres.
