Status cards and derived-score sheets read one way: they state a verdict and
end there. The metric pages already carried the hand-off; the score sheets
passed neither an opener nor a scope, so they painted no action at all.
- Score sheets (sleep / readiness / recovery / stress / strain) gain the same
auto-sent opener the metric pages use, each scoped to the inputs that drive
the composite rather than to a block it has no equivalent of.
- Workout detail's coach launch carries the workout itself. The chat request
gains an optional workoutId; on the FIRST turn the route narrows by
{ id, userId } and pins ONE bounded evidence section onto the snapshot.
Later turns reuse the pinned snapshot, so per-turn work stays constant in
conversation length.
- /coach?workout=<id> covers the full-page and maximize paths.
The workout block deliberately does not take the fenced transport the stored-
document path takes: a workout row is the user's own sensor record, and the
projection admits no free text. That is enforced, not assumed — sport_type is
a TEXT column, so it is re-asserted against the closed sport union, metadata
is excluded apart from its numeric zone durations read through a Zod slice,
and a recursive guard throws on any non-numeric leaf.
Own-history sport averages move to src/lib/workouts/sport-context.ts so the
narrative and the detail page cannot quote different figures.
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— theapiHandlerwrapper 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 QueryqueryKey/mutationKeyarrays (enforced by an ESLint rule); per-feature files behind theindex.tsbarrel.safe-fetch.ts— the one documented outbound-egress entry (redirect: "manual"+ timeout; optional connect-time DNS-rebinding pin). Rawfetch(underlib/+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-channelsenders/, retry policy, VAPID config.jobs/— pg-boss workers: reminders, insight pre-generation, backups, retention sweeps, integration backfills. Recurring work belongs here, not inscripts/.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 medicationcompliance.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 fordocs/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 SSRFisPublicUrlfloor.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__/.
