The recurring no-briefing day had a chain of causes, closed end to end: Every failure path in the nightly pregenerate + the comprehensive generator now annotates a queryable cause (several classes — features-error, payload-too-large, aborted, generator-failed — previously bumped a counter with zero trace). A failed nightly warm enqueues one bounded retry ~45 minutes later (singleton per user, existing budgets apply), so a transient provider hiccup heals before morning. A cached payload that carries NO briefing no longer satisfies the 24h POST short-circuit nor the unchanged-content hash gate — a once-stripped briefing could previously block its own regeneration indefinitely. The card surfaces the omission reason persistently (grounding strip, generation failure, not attempted) with a forcing retry. Documentation corrected against code truth: Withings credentials are per-user (the documented env path never existed; the dead example entries and manifest rows are gone, and WITHINGS_WEBHOOK_SECRET is now actually whitelisted in compose — stock deploys could never deliver it); the classic Fitbit portal no longer accepts new registrations; the backup-restore example no longer mints a fresh encryption key and uses pnpm dlx tsx; the TLS guide describes the real client model (two CA-level SPKI pins, any-match, leaf renewals need no build); scaling/admin references fixed; the operator-shared subscription provider is documented.
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 renamedmiddleware). 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 inapiHandler. Seeapp/README.md.lib/— the server/runtime toolkit:apiHandler, auth, crypto, rollups, AI, notifications, pg-boss jobs, integrations, rate limiting. Seelib/README.md.components/— React components (shadcn/ui new-york, kebab-case files). Seecomponents/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 byprisma 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.
