Largest feature delta in the v1.4.x line. Insights expands into seven dedicated metric sub-pages; GLP-1 medication tracking lands end-to-end (drug-level chart with Research Mode acknowledgment, EMA titration ladder, cadence + compliance, side-effect taxonomy, pen/vial inventory); cross-source priority becomes a two-axis resolver; per-user timezone threads through ten analytics surfaces; Withings activity + sleep v2 sync; onboarding rebuilt as a nested-route wizard; Personal Records ship end-to-end; Health Score provenance accordion; Coach runs native first-party prompts across six locales with a 1800-assertion refusal-probe matrix; OpenAPI drift gate hard-fails; multi-arch GHCR image. Migrations 0043 through 0060 are additive and forward-only. PROMPT_VERSION 4.24.0 → 4.25.0 with GROUND RULE 9 (refuses dose recommendations) and GROUND RULE 15 (refuses drug-level estimates with MDR + MDCG 2021-24 cites).
See CHANGELOG.md for the full per-section delta.
`POST /api/measurements/batch` accepts up to 500 HealthKit-shaped
entries per call, runs each through the new mapping helper, and writes
them under `source = APPLE_HEALTH` with the inbound sample UUID as the
external id. The composite unique index on
`(user_id, type, source, external_id)` does the per-entry dedup;
`Idempotency-Key` covers the batch-level retry case so the iOS observer
queue can replay in flight without double-writing.
Per-entry status (`inserted` / `duplicate` / `skipped`) lets the
client advance its sync cursor accurately even when individual rows
land on different paths. Skip reasons cover unknown HealthKit
identifiers and out-of-plausible-range values so a single bogus sensor
reading never rejects an otherwise clean batch.
Insertion uses chunked `createMany` with `skipDuplicates: true` so a
race between two concurrent retries reconciles cleanly via the unique
index instead of failing the transaction. Wide Event annotation logs
`processed / inserted / duplicates / skipped` for ops visibility.
Six integration tests against a real Postgres testcontainer cover the
happy path, the per-entry duplicate path, the over-cap 422, mixed
unmappable + out-of-range entries, per-stage sleep rows, and
`Idempotency-Key` replay.
