Marc-André Bombeck 7e48e2c26d fix(insights): stop the daily briefing going blank on slow generations
The comprehensive insight that feeds both the daily briefing and the
insights trend narrative is a single reasoning-heavy generation over the
full feature snapshot. On a large account it runs past the provider
client's fixed 60 s timeout and is aborted mid-stream, so the chain
reports an all-failed outcome, no cached block is written, and the
surface falls back to its static placeholder on every visit. The warm
paths bounded the same generation tighter still (45 s) and counted the
failure with no observable signal, so the blank state was permanent and
silent.

Make the per-request upstream timeout configurable
(CompletionParams.timeoutMs, default 60 s for every existing caller) and
raise it to 120 s for the comprehensive surface only, across all three
generation paths: the on-demand regenerate, the on-demand warm, and the
nightly pre-generation. Raise the warm-pass budget to 130 s so the
provider's own timeout governs a genuine completion rather than clipping
it early. Annotate the comprehensive failure in both the generator and
the nightly loop so a generation that keeps failing is queryable instead
of leaving the surface empty without a trace.

src/lib/

The server and runtime toolkit. Everything that is not a page, component, or route handler lives here: the API kit, auth, crypto, the rollup tier, AI providers, notifications, background jobs, and the integration clients. Route handlers and RSC pages compose these modules; the modules never reach back into app/.

Core request kit

  • api-handler.ts — the apiHandler wrapper every route uses. Auth resolver (cookie OR Bearer), requireAuth / requireAdmin (admin is cookie-only by construction), idempotency plumbing, Wide-Event builder, GlitchTip forwarder.
  • api-response.ts — the { data, error, meta? } envelope: apiSuccess / apiError, safeJson, trusted-proxy IP resolver, returnAllZodIssues + sanitiseZodIssues.
  • rate-limit.ts — Postgres-backed sliding-window limiter (single atomic upsert); multi-instance correct.
  • idempotency.ts — user-scoped idempotency keys that refuse to cache secret-shaped responses.
  • query-keys/ — the only legal source of TanStack Query queryKey / mutationKey arrays (enforced by an ESLint rule); per-feature files behind the index.ts barrel.
  • safe-fetch.ts — the one documented outbound-egress entry (redirect: "manual" + timeout; optional connect-time DNS-rebinding pin). Raw fetch( under lib/ + app/ is banned by ESLint.
  • db.ts — the Prisma client singleton.
  • crypto.ts — AES-256-GCM at rest with versioned key ids, fail-closed loader, rotation primitives.

Subsystems

  • auth/ — Postgres sessions, secure-cookie flag policy, passkey (WebAuthn) + Argon2id password, per-device refresh-token rotation, HMAC Bearer tokens.
  • ai/ — multi-provider insight + Coach engine: provider-chain.ts, hand-rolled {openai,anthropic,local,codex,mock}-client.ts, coach/, prompts/, citation + confidence helpers.
  • rollups/ — DAY/WEEK/MONTH/YEAR pre-aggregations for measurements, mood, and medication compliance. Read-swap pattern: probe the rollup, fall back to live SQL on a coverage miss.
  • notifications/ — the dispatcher cascade (APNs → Telegram → ntfy → Web Push), per-channel senders/, retry policy, VAPID config.
  • jobs/ — pg-boss workers: reminders, insight pre-generation, backups, retention sweeps, integration backfills. Recurring work belongs here, not in scripts/.
  • integrations/, withings/, whoop/, fitbit/ — OAuth clients and sync services for the device providers; sync/ holds the shared delta-feed plumbing.
  • analytics/ — trend calculations, cadence-aware medication compliance.ts, correlations.
  • insights/, fhir/, doctor-report-*.ts — insight pipeline, FHIR R4 export, client-side doctor-report PDF.
  • openapi/ — Zod registry that is the source of truth for docs/api/openapi.yaml.
  • logging/, observability/, monitoring/ — Wide-Event transports and the central redaction denylists (redact at the egress boundary, not the call site).
  • validations/ — shared Zod schemas, including the SSRF isPublicUrl floor.
  • i18n/, tz/ + timezone.ts, format*.ts — translations, timezone helpers (Berlin for display, UTC in DB), locale formatting.

Conventions

Kebab-case filenames. See ../../CLAUDE.md "Code conventions" and "Security-relevant patterns"; the critical-files map there cites the exact entry points. Most modules carry tests in a sibling __tests__/.
