Three additive Prisma additions land in one commit so the v1.4.39 wave
agents (W-MOOD, W-MED, W-SUM) build against a stable generated client:
- `mood_entry_rollups`: per-(user, granularity, bucket) mood stats
(count / mean / min / max / sd). Reuses the existing
`measurement_rollup_granularity` enum.
- `medication_compliance_rollups`: per-(user, medication, day)
scheduled / taken / skipped triple. `day` is the user-tz-anchored
YYYY-MM-DD string so multi-instance reads do not re-derive boundaries.
- `measurement_rollups.sum_value`: nullable column. Cumulative-metric
read paths consume it directly; boot backfill folds NULLs on first
reach.
Migrations 0070 / 0071 / 0072 use IF NOT EXISTS + DO $$ EXCEPTION WHEN
duplicate_object guards (mirror 0061 / 0067 / 0069). No ALTER on
existing tables that downgrade row contracts, no DROP. Backward-safe
read paths land in the wave agents that follow.
Includes `.planning/round-v1438-perf-analysis.md` — the read-only audit
that anchors the wave plan.
