Marc-André Bombeck b1e36d9fb0 reconcile: fold in the outstanding hardening and data-integrity fixes
Merge the eight reviewed audit fixes that were cut a week ago and never
landed. Main has moved on since, so each fix was re-checked against the
current tree and each of the five conflicts resolved by understanding
both sides.

Kept, still open on main:
- Proxy early exits now carry the transport security header subset via a
  shared helper. Reconciled with main's /api/health worker-only carve-out.
- Batch measurement ingest bounds the entry instant so a future-dated row
  can no longer win "latest reading" or poison the rollup buckets.
- Web Push dials through the pinned safeFetch dispatcher with
  requirePublicHost, closing the last user-controlled-host egress.
- Mood bulk upsert and its tag/factor links run in one transaction, so a
  rejected rating rolls the mood row back instead of leaving a tagless row.
- Full backup carries NutrientIntakeDay with its unit and source. Folded
  into main's portable-export / disaster-recovery split.
- Live daily-series fallback restores the min/max spread band the tiered
  read already emitted.
- Coach stream aborts its in-flight reader on unmount and resets send state
  on a conversation switch.
- Manual water writes share the day-bound helper, nutrient add clamps after
  the increment, and the thiamin cap drops to a real supplement ceiling.
- Compliance point window widens symmetrically instead of wrapping overnight.
- Oura, Polar and Fitbit token helpers classify an empty or non-JSON 2xx
  body as a handled transient error.
- WebAuthn relying-party fallback to localhost is gated to development.
- Chart-token strip list is derived from the allowlist and pinned by a test.
- Regression tests pin the snapshot-cache tenant key, the GlitchTip
  path-secret redaction and the Withings credentials delete.

Superseded by main, tests re-pointed at the current shape:
- The intake CSV import was rewritten on main to run through a background
  job with a single-active-job admission gate. The future-date bound is
  re-applied at request validation and the per-user limiter is kept for
  parity with the bulk twin; the old synchronous-write test is replaced.

HealthLog API Spec

openapi.yaml is the canonical OpenAPI 3.1 description for the HealthLog Next.js API. It is the source of truth for the native iOS client's DTO codegen.

The MCP server is documented separately — it is a distinct contract over JSON-RPC, not part of the REST OpenAPI spec:

Preview locally

Open an interactive Redoc preview in your browser:

npx @redocly/cli preview docs/api/openapi.yaml

Generate static HTML for sharing:

npx @redocly/cli build-docs docs/api/openapi.yaml --output docs/api/index.html

Validate

npx @redocly/cli lint docs/api/openapi.yaml

The spec is expected to be lint-clean (errors = 0). Some warnings are intentional:

  • no-server-example.com — http://localhost:3000 is the dev server.
  • operation-2xx-response / operation-4xx-response — webhook + redirect endpoints intentionally omit one or the other.
  • no-unused-components — ReminderPhase is exposed for client codegen even though no path response references it directly.

Layout

  • info — title, version (mirrored from package.json), description.
  • servers — production https://healthlog.bombeck.io plus http://localhost:3000 for local development.
  • tags — domain groupings (Auth, Measurements, Medications, Mood, Dashboard, Insights, Achievements, DoctorReport, Integrations, User, Tokens, Notifications, Onboarding, Health, Settings, Analytics, Export, AuditLog, Monitoring, Webhooks, Ingest, Admin).
  • securitySchemes:
    • bearerAuth — long-lived hlk_* API tokens issued via POST /api/tokens. Required on /api/ingest/medication.
    • sessionCookie — HttpOnly healthlog_session cookie set by the password and passkey login flows. Used by the web app and any iOS client running inside a web view.
  • components.schemas — DTOs for all routes plus the underlying Prisma models (e.g. Measurement, Medication, MedicationIntakeEvent, MoodEntry, User, DashboardLayout, ApiEnvelope, ApiError).
  • paths — all routes from src/app/api/**/route.ts, including the /api/admin/* family which is tagged Admin and marked internal.

Conventions

  • Successful responses use the envelope { data, error: null }.
  • Error responses use the envelope { data: null, error: '<message>' }.
  • Pagination uses limit + offset query parameters and a meta: { total, limit, offset } block on the response.
  • All timestamps are ISO 8601 / RFC 3339 (format: date-time) in UTC.
  • IDs are CUIDs (opaque strings).

Updating the spec

When adding or changing routes:

  1. Update the relevant route handler under src/app/api/**/route.ts.
  2. Mirror the change in openapi.yaml. Keep operationId camelCase and stable — the iOS codegen keys off it.
  3. Run npx @redocly/cli lint docs/api/openapi.yaml and resolve all errors. Warnings are tolerated when documented above.
  4. Bump info.version if the change is breaking for clients.
