Marc-André Bombeck 9bbd8a89dc chore(release): v1.28.35 — timestamps honor the profile timezone
Client-rendered times fell back to the hardcoded display zone
(Europe/Berlin) because neither useFormatters() nor the legacy format.ts
helpers ever received users.timezone. A third localStorage mirror
(timezone-mirror.ts, following the time-format/date-format pattern)
carries the validated profile zone from /api/auth/me into both read
paths; the fallback chain is strictly profile → Europe/Berlin — never
the browser zone, so screen, PDF, and export cannot disagree.
makeFormatters validates its zone before Intl (a poison value falls back
instead of throwing inside every render).

Same pass, per the two-document audit: formatUpdatedLabel boundary and
clock now resolve one zone in every state (the undefined-tz browser hole
is closed); @db.Date calendar fields render UTC-pinned so profiles west
of UTC cannot shift a day; dose-history day headings and GLP-1 weekday
labels derive from the display zone; chart day/month labels are
encoding-derived and UTC-pinned (bucket math untouched, byte-identical
for Berlin profiles); the clinician share view renders in the patient's
timezone instead of the container's; Playwright pins Europe/Berlin.
Server day-key semantics, streak anchoring, insight cache keys, and
verbatim wall-clock strings are untouched by construction and pinned by
the new Auckland/New_York/Manila + DST test matrix.

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.
