Marc-André Bombeck d4be568625 chore(release): v1.28.42 — snappier lists, correct mood refresh, safer first sign-up
Performance + correctness fixes from the campaign's verified perf-correctness
audit (the two server-query findings — comprehensive-generate + boot-discovery
distinct — are deferred to a careful separate perf release):

- format-locale built a fresh Intl.DateTimeFormat/NumberFormat per call
  (main-thread stall across every history list). Routed through the existing
  process-wide formatter-cache keyed on locale + options (timeZone + hour-cycle
  in the key); output byte-identical.
- measurement-list rendered every row twice (desktop table + mobile cards, one
  CSS-hidden), unvirtualized. Now renders one layout via the SSR-safe
  useIsMobile(md) hook; row markup + every data-slot unchanged.
- moodDependentKeys omitted dashboardSnapshot(), so a mood write left the
  dashboard tile/score stale ~120s (server cache was already correct). Added it.
- register first-user admin was a count-then-create race (two concurrent
  first sign-ups could both become ADMIN). Now an advisory lock + in-transaction
  re-count makes first-admin atomic; P2002 maps to 409 instead of 500.

Regression test per fix. No migration (0243 still free).

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.
