Marc-André Bombeck b1b76ab68a fix(score): grade weight against the user's own target, never a fabricated one
The Health Score graded the weight pillar against 22 x height squared,
expanded by 2 kg either side: a target nobody set, nothing disclosed,
and the only producer of the pillar's band. For anyone with a height on
file it pre-empted both the honest trend-only path the module header
promised and the null-redistribution behind it, while the target the
user had actually entered sat unread in User.thresholdsJson.

computeHealthScore now takes the band whole plus the yardstick it came
from. Both callers resolve it through one shared builder next to
buildHealthScoreBpInputs, which hands over a band only when
getEffectiveRange reports a real user override; every other account
scores the bare trend. defaultWeightTargetFromHeight is gone.

Same pass, same defect class elsewhere: the dashboard bands, the
weight-drift verdict rung and the weight/BMI record direction all
ignored an explicit target too, and the snapshot never resolved the
mood module, so a mood-off account got a mood pillar in the hero ring
and none in the Insights card. moodEnabled and the weight yardstick are
required parameters now, so a caller that forgets one fails to compile
instead of quietly scoring against a default.

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__/.
