Marc-André Bombeck 47a5079cfa feat(api): say why a module's surfaces are not there, not only that they are not

`GET /api/auth/me` publishes a boolean per module, and three different
situations collapse into the same `false`: the record has the module switched
off, the active grant's sections do not open it, or the operator switched it
off for the whole instance. A client holding the boolean has to guess between
them, so the empty state either says nothing or says something that may be
untrue -- offering a delegate a switch that is not theirs to reach, or telling
an account holder to turn on a module the operator removed.

`moduleAccess` carries the reason beside the booleans, which keep their exact
meaning: `enabled`, `disabled`, `not_granted`, `unavailable`, resolved
outside-in so the reason published is the one nothing further in can change.
`modules[key]` stays exactly `moduleAccess[key] === "enabled"` for every key,
and the two halves are built independently -- the boolean still runs through
`maskModulesToSections` -- so the test of that pairing is an assertion rather
than a restatement of a derivation. It is checked on the pure builder across a
matrix of grants, records and operator blobs, and again on the real route for a
scoped delegate, an unscoped one, and an operator-disabled module.

Both ends in one change, because a payload field with no reader is the failure
this repository keeps rediscovering. The reader is `ModuleDisabledNotice`, the
shared module-off empty state the empty-states audit asks for: it names the
reason in the reader's own language and offers the enable control only when the
record's own switch is what is off, since neither of the other two is fixable
from that page. The nutrients page adopts it and drops its bespoke block, which
had been handing every delegate a button that would refuse them.

Registered in the OpenAPI registry as `ModuleAccessMap` and carried on the
account payload; the native contract gains a field and loses nothing, since a
Bearer request carries no switch and never reads `not_granted`.

HealthLog API Spec

openapi.yaml is the OpenAPI 3.1 description for the HealthLog Next.js API and the source of truth for the native iOS client's DTO codegen. The file is generated: pnpm openapi:generate emits it from the Zod registry under src/lib/openapi/ (registry.ts plus the route modules in src/lib/openapi/routes/). Do not edit the YAML by hand; the next generation overwrites it, and CI (openapi:check) fails the build when the committed YAML drifts from the registry.

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

mcp-capabilities.md — the tool, resource, and prompt catalogue, the grounding contract, and the write model.
mcp-skills.md — building a connector or skill on top of it.
../self-hosting/mcp.md — enabling and connecting the surface (operator guide).

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

The spec is expected to be lint-clean (errors = 0). Warnings such as no-server-example.com for the localhost dev server are tolerated; re-run the lint to see what it produces against the current file before treating a warning as a regression.

Layout

info — title, description, and version mirrored automatically from package.json at generation time. Never bump it by hand.
servers — https://healthlog.example.com as the self-hosted placeholder plus http://localhost:3000 for local development.
tags — domain groupings; the current set lives at the top of the generated file (Auth, Measurements, Medications, Mood, Analytics, Insights, Consent, Dashboard, Notifications, Devices, Export, Sync, Cycle, MeasurementReminders, Labs, Illness, Documents, Records, Admin, Meta, Retired).
securitySchemes:
- bearerAuth — hlk_* API tokens. A scope grants what it names and nothing adjacent, so where a token comes from decides what it reaches:
  - a completed password / passkey / refresh exchange mints the cookie-equivalent ["*"] token the native client carries;
  - a medication's own API-endpoint toggle mints medication:ingest plus medication:<id>:ingest, the pair /api/ingest/medication gates on;
  - POST /api/mcp/tokens mints health:read (optionally plus health:write), audience-bound to /mcp and refused on REST writes;
  - POST /api/tokens/measurements mints measurements:write, accepted by POST /api/measurements and POST /api/measurements/batch only, on the holder's own record only.
  POST /api/tokens is not among them — that generic mint was removed in v1.30.17. The path still lists (GET) and revokes (DELETE /api/tokens/{id}) every token above, whichever surface issued it.
- 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 the documented routes plus the underlying Prisma models (e.g. Measurement, Medication, MedicationIntakeEvent, MoodEntry, User, DashboardLayout, ApiEnvelope, ApiError).
paths — the client-facing REST surface. Not every src/app/api/**/route.ts is in the contract: most /api/admin/* routes, the OAuth connect/callback legs, and the webhook surfaces are not documented here. The Retired tag lists removed paths that answer 410 Gone.

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:

Update the relevant route handler under src/app/api/**/route.ts.
Change the Zod schemas and their .meta() registrations under src/lib/openapi/ (registry entry plus the matching module in src/lib/openapi/routes/). Keep operationId camelCase and stable; the iOS codegen keys off it.
Run pnpm openapi:generate and commit the regenerated openapi.yaml alongside the schema change. CI's openapi:check fails on drift.
Never edit the YAML directly and never bump info.version by hand; the version follows package.json at generation time.
