Marc-André Bombeck 72b1d1ef8a feat(oura): ingest the vO2_max and daily_stress collections
The Oura v2 client fetched sleep, readiness, activity, daily sleep, and
daily SpO2 but skipped the dedicated vO2_max collection and daily_stress.
An Oura user got no VO2max from any path even though the enum, the
cardio-fitness page, fitness-age, norms, and the LOINC code already exist.

Add fetchVo2Max + mapVo2Max (vo2_max -> VO2_MAX, mL/(kg·min)) and
fetchDailyStress + mapDailyStress. Oura exposes no headline stress score,
only minutes in high stress vs high recovery, so derive a bounded 0-100
STRESS_SCORE from the high-stress share of the day's charged time. Both
collections wire into the existing reactive-refresh sync tail; no
migration, no schema change, no iOS-contract impact.

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.
