Marc-André Bombeck 9a47b4db49 fix(mood): refuse a forecast below the data floor on the read path, not only in the job
The job clears a below-floor account's rows nightly, but the read path
trusted whatever row was on disk between passes. So for up to a day
after an account deleted entries back under the floor, GET
/api/mood/prognosis returned present:true with a value the account no
longer had the data to support — and worse, under a stage the row
implied ("insufficient" / "learning") that is not in the published enum,
which fails a strict client decode of the whole payload.

The read path now re-reads the ladder and returns the absence shape
below the floor, exactly as the job would, so the two agree and no
out-of-enum stage can reach the wire. The present type's stage is
narrowed to the three rungs that carry a value, so the compiler enforces
it too.

The integration case that missed this ran the job before reading, which
is precisely why it was silent. The new case deletes entries back into
the learning band and reads WITHOUT running the job, with the row still
proven on disk, and asserts present:false with no stage. Watched red:
before the fix it returned present:true with a predicted value.

src/

Application source. HealthLog is a Next.js 16 App Router project (output: "standalone", React 19, TypeScript strict). The path alias @/* resolves to this directory. Everything a request touches lives under here; the layout below follows the request flow rather than alphabetical order.

Request flow

client → src/proxy.ts → src/app/<route>/route.ts → src/lib/api-handler.ts → handler body → src/lib/api-response.ts → client
  • proxy.ts — the HTTP edge (Next.js 16's renamed middleware). Public-path allowlist, demo-mode mutation block, server-side onboarding redirect, worker-only refusal, x-request-id + CSP nonce generation, every security header.
  • app/ — App Router pages (RSC by default) and API routes. Every API route wraps its handler in apiHandler. See app/README.md.
  • lib/ — the server/runtime toolkit: apiHandler, auth, crypto, rollups, AI, notifications, pg-boss jobs, integrations, rate limiting. See lib/README.md.
  • components/ — React components (shadcn/ui new-york, kebab-case files). See components/README.md.

Other directories

  • hooks/ — shared React hooks (use- prefix, kebab-case).
  • types/ — shared TypeScript declarations.
  • generated/prisma/ — the generated Prisma client (do not edit; regenerated by prisma generate). Imported as @/generated/prisma.
  • instrumentation.ts — Next.js startup hook; boots the pg-boss worker registry and boot-time backfill queues.
  • __tests__/ — cross-cutting unit tests; most tests live in __tests__/ folders next to the code they cover.

Conventions

See ../CLAUDE.md for the full set. The load-bearing ones: RSC by default ("use client" only when a hook/state/browser API needs it); every API route wraps apiHandler and parses its body with Zod safeParse; userId is always narrowed from session or Bearer, never accepted as a body field; TanStack Query keys come only from src/lib/query-keys/; outbound HTTP goes through src/lib/safe-fetch.ts.
