Strava's token endpoint does not answer RFC 6749 errors. A refresh
token it no longer honours, after the athlete revoked the app or the
token was rotated away, is a 400 with the API's generic Fault:
{"message":"Bad Request","errors":[{"resource":"RefreshToken",
"field":"refresh_token","code":"invalid"}]}. The classifier looked for
invalid_grant, which never arrives, so the failure was booked
persistent and the connection never asked for a reconnect.
The token error now carries the fault reduced to its resource, field
and code (or an RFC error code, should one arrive), and the classifier
lifts a 400 naming RefreshToken to reauth_required, from the error and
from its message after a retry loses the prototype. Every other refusal
is classified by its status as before, including the faults that name
the Application.
Strava documents the Fault and Error model but not these values; the
body is the one several unrelated client libraries captured from live
traffic between 2023 and 2026.
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__/.
