Marc-André Bombeck de8eadbf2f fix(ai): keep setup invitations away from people who opted out
A person who switched both the Coach and AI analysis off under Settings,
Modules still got invited to set AI up: the Insights hint, its copy in
Settings, AI, the checklist row and the onboarding panel all keyed on
`provider.canConfigure`, which only knows the record kind and the
operator switch.

The flag itself stays as it is, because the AI usage card and the consent
request read it too and still serve document reading, lab photos and
medication extraction. The three invitation readers now also check the
module map through `hasOptedOutOfAi`.

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 (Wide-Event builder, error envelope, GlitchTip forwarder) and the one public entry for the request guards in auth/guards/: the auth resolver (cookie OR Bearer), requireAuth / requireRecordAuth / requireAdmin (admin is cookie-only by construction), the step-up gates.
  • 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__/.
