Squashed merge of the v1.4.39 wave work from develop. The release
extends the v1.4.38 fast-path posture to two more endpoints that
still walked the source table on every cold mount and folds a
cumulative `sum_value` column into the existing rollup tier so step /
flight / distance / daylight / active-energy sparklines no longer
re-derive their daily totals in Node.
Raw measurements / mood_entries / medication_intake_events tables are
byte-unchanged. Three new tiers (mood_entry_rollups,
medication_compliance_rollups, measurement_rollups.sum_value) are
derived caches that self-heal via boot-time backfill on first reach.
Migrations 0070, 0071, 0072 are additive only. The sum_value column
add is catalog-only DDL on PostgreSQL 11+ — no table rewrite, writes
resume in milliseconds. No environment-variable change. No API
contract break. No iOS contract change.
Expected wins (live perf-verify rides the post-deploy window):
- /api/mood/analytics cold 12.7 s -> ~200 ms
- /api/medications/intake?scope=compliance cold 3.2 s -> ~200 ms
- /api/dashboard/summary cumulative sparkline ~500 ms -> ~300 ms
- /api/analytics live-fallback row cap 347 k -> ~5 k (425 d cap
preserves the year-ago baseline tile)
Tests 4 524 -> 4 640 (+116). Typecheck clean. Lint clean.
