Marc-André Bombeck 076c2f9c5d fix(auth): sign out the other devices, lose a refresh to a revocation, key the replay cache by authority
"Sign out everywhere" revoked every other refresh token and nothing else.
A native login is two rows, and the Bearer check consults only the
paired access token, so the other phones kept working until that token
expired, up to a day on the default policy. The route also handed
destroyOtherSessions a session-kind credential for a Bearer caller, whose
session.id is the ApiToken row id; the exception matched nothing and the
calling phone revoked its own refresh token. destroyOtherSessions now
finds the paired access tokens through the refresh rows and revokes them
inside the same transaction, reporting the count, and the route names a
Bearer caller by its access-token hash. Programmatic tokens are untouched.

rotateRefreshToken marked the consumed row under usedAt: null alone, so a
revocation landing between the read and the write was overtaken and a
pair minted after the family ended stayed live. The guard now includes
revokedAt: null; on a lost race the minted pair is retired and the reason
distinguishes a revoked family from a double consume.

withIdempotency consulted the grant only at replay time, and only for its
existence; a narrow-scoped token was checked only on the delegated arm.
Both move into the cell key: a delegated cell carries the grant's id,
level and scope fingerprint, a narrow token's cells carry the token, and
a request with no live grant neither reads nor claims a cell. Cookie and
wildcard own-record cells are keyed byte-for-byte as before.

Tests: integration for the paired access tokens (cookie and Bearer
caller), a deterministic revoke-mid-rotation race against Postgres, unit
coverage for the new cell keys, and the structural guard moved to the
new invariant.

src/

Application source. HealthLog is a Next.js 16 App Router project (output: "standalone", React 19, TypeScript strict). The path alias @/* resolves to this directory. Everything a request touches lives under here; the layout below follows the request flow rather than alphabetical order.

Request flow

client → src/proxy.ts → src/app/<route>/route.ts → src/lib/api-handler.ts → handler body → src/lib/api-response.ts → client
  • proxy.ts — the HTTP edge (Next.js 16's renamed middleware). Public-path allowlist, demo-mode mutation block, server-side onboarding redirect, worker-only refusal, x-request-id + CSP nonce generation, every security header.
  • app/ — App Router pages (RSC by default) and API routes. Every API route wraps its handler in apiHandler. See app/README.md.
  • lib/ — the server/runtime toolkit: apiHandler, auth, crypto, rollups, AI, notifications, pg-boss jobs, integrations, rate limiting. See lib/README.md.
  • components/ — React components (shadcn/ui new-york, kebab-case files). See components/README.md.

Other directories

  • hooks/ — shared React hooks (use- prefix, kebab-case).
  • types/ — shared TypeScript declarations.
  • generated/prisma/ — the generated Prisma client (do not edit; regenerated by prisma generate). Imported as @/generated/prisma.
  • instrumentation.ts — Next.js startup hook; boots the pg-boss worker registry and boot-time backfill queues.
  • __tests__/ — cross-cutting unit tests; most tests live in __tests__/ folders next to the code they cover.

Conventions

See ../CLAUDE.md for the full set. The load-bearing ones: RSC by default ("use client" only when a hook/state/browser API needs it); every API route wraps apiHandler and parses its body with Zod safeParse; userId is always narrowed from session or Bearer, never accepted as a body field; TanStack Query keys come only from src/lib/query-keys/; outbound HTTP goes through src/lib/safe-fetch.ts.
