Marc-André Bombeck ae2e39198a feat(google-health): import blood glucose, core body temperature, and nightly wrist temperature
Full-catalogue coverage pass against the v4 data-types index. Three types
map onto existing MeasurementTypes and are now fetched in the metrics
bundle:

- blood-glucose -> BLOOD_GLUCOSE. `bloodGlucoseMilligramsPerDeciliter` is
  already the canonical mg/dL storage unit; meal/timing/specimen enums are
  not stored.
- core-body-temperature -> BODY_TEMPERATURE. `temperatureCelsius`, the core
  slot — distinct from the surface-temperature buckets.
- daily-sleep-temperature-derivations -> WRIST_TEMPERATURE. The documented
  `nightlyTemperatureCelsius` is an ABSOLUTE reading (the mean of the
  night's skin-temperature samples), which refutes the earlier deviation-
  only premise behind the launch omission. The baseline/stddev derivations
  are not stored — the user's own series carries the baseline.

Every other catalogue type is now an explicit documented skip in
mapping.md with its reason (per-sample twins of the chosen daily grains,
zone-minutes types without a HealthLog concept, total-calories folding in
BMR, hydration/nutrition without a module, ECG/IRN behind their scope
policy). The structure probe iterates the type table, so the three new
types are probed automatically.

src/lib/

The server and runtime toolkit. Everything that is not a page, component, or route handler lives here: the API kit, auth, crypto, the rollup tier, AI providers, notifications, background jobs, and the integration clients. Route handlers and RSC pages compose these modules; the modules never reach back into app/.

Core request kit

  • api-handler.ts — the apiHandler wrapper every route uses. Auth resolver (cookie OR Bearer), requireAuth / requireAdmin (admin is cookie-only by construction), idempotency plumbing, Wide-Event builder, GlitchTip forwarder.
  • api-response.ts — the { data, error, meta? } envelope: apiSuccess / apiError, safeJson, trusted-proxy IP resolver, returnAllZodIssues + sanitiseZodIssues.
  • rate-limit.ts — Postgres-backed sliding-window limiter (single atomic upsert); multi-instance correct.
  • idempotency.ts — user-scoped idempotency keys that refuse to cache secret-shaped responses.
  • query-keys/ — the only legal source of TanStack Query queryKey / mutationKey arrays (enforced by an ESLint rule); per-feature files behind the index.ts barrel.
  • safe-fetch.ts — the one documented outbound-egress entry (redirect: "manual" + timeout; optional connect-time DNS-rebinding pin). Raw fetch( under lib/ + app/ is banned by ESLint.
  • db.ts — the Prisma client singleton.
  • crypto.ts — AES-256-GCM at rest with versioned key ids, fail-closed loader, rotation primitives.

Subsystems

  • auth/ — Postgres sessions, secure-cookie flag policy, passkey (WebAuthn) + Argon2id password, per-device refresh-token rotation, HMAC Bearer tokens.
  • ai/ — multi-provider insight + Coach engine: provider-chain.ts, hand-rolled {openai,anthropic,local,codex,mock}-client.ts, coach/, prompts/, citation + confidence helpers.
  • rollups/ — DAY/WEEK/MONTH/YEAR pre-aggregations for measurements, mood, and medication compliance. Read-swap pattern: probe the rollup, fall back to live SQL on a coverage miss.
  • notifications/ — the dispatcher cascade (APNs → Telegram → ntfy → Web Push), per-channel senders/, retry policy, VAPID config.
  • jobs/ — pg-boss workers: reminders, insight pre-generation, backups, retention sweeps, integration backfills. Recurring work belongs here, not in scripts/.
  • integrations/, withings/, whoop/, fitbit/ — OAuth clients and sync services for the device providers; sync/ holds the shared delta-feed plumbing.
  • analytics/ — trend calculations, cadence-aware medication compliance.ts, correlations.
  • insights/, fhir/, doctor-report-*.ts — insight pipeline, FHIR R4 export, client-side doctor-report PDF.
  • openapi/ — Zod registry that is the source of truth for docs/api/openapi.yaml.
  • logging/, observability/, monitoring/ — Wide-Event transports and the central redaction denylists (redact at the egress boundary, not the call site).
  • validations/ — shared Zod schemas, including the SSRF isPublicUrl floor.
  • i18n/, tz/ + timezone.ts, format*.ts — translations, timezone helpers (Berlin for display, UTC in DB), locale formatting.

Conventions

Kebab-case filenames. See ../../CLAUDE.md "Code conventions" and "Security-relevant patterns"; the critical-files map there cites the exact entry points. Most modules carry tests in a sibling __tests__/.
