Tasks — @suaveplan/api-auth-jwt

Every checkbox MUST reflect work actually done in this change.

0. Pre-flight (non-negotiable)

• 0.1 Confirm clean working tree (git status reports nothing) and no in-flight worktrees with uncommitted work (git worktree list then git status in each)
• 0.2 If any worktrees exist under .claude/worktrees/, account for each one: still-active agent, work-pending-merge, or stale-and-prune. Stale worktrees MUST be removed (git worktree remove) before opening a new one — code that has been lost twice on main is the failure mode this guards against.
• 0.3 Confirm the package set in MANIFEST.md matches find packages -maxdepth 3 -name package.json count. Drift here means a prior change archived without regenerating the manifest.

1. Spec authoring

• 1.1 Read design doc (§2.3, §5.2a, §13.4)
• 1.2 Read openspec/changes/api-auth/ for upstream contract
• 1.3 Read openspec/AGENTS.md Sections 13 and 14
• 1.4 Draft proposal.md
• 1.5 Draft specs/api-auth-jwt/spec.md
• 1.6 Every requirement carries **Verified by:**

2. Implementation

• 2.1 Scaffold packages/api/api-auth-jwt/ ("version": "0.1.0", "sideEffects": false, deps: api-auth, api-types, api-worker-rpc, jws, error, zod)
• 2.2 src/options/jwt-session-resolver-options.ts — Zod schema
• 2.3 src/factory/create-jwt-session-resolver.ts — direct surface
• 2.4 src/proxy/create-jwt-session-resolver-worker-proxy.ts — proxy surface
• 2.5 src/jwks/jwks-cache.ts — TTL + ETag + kid miss refresh
• 2.6 src/claim-mapping/default-claim-to-principal.ts — claims → Principal
• 2.7 src/security-scheme/security-scheme-contribution.ts — OpenAPI securitySchemes block
• 2.8 src/error-codes.ts — AUTH_JWT_* codes via defineCodes
• 2.9 src/index.ts — explicit named re-exports

3. Tests

• 3.1 src/factory/create-jwt-session-resolver.test.ts
• 3.2 src/factory/create-jwt-session-resolver.spec-conformance.test.ts — runAuthSessionConformance("jwt-direct", ...)
• 3.3 src/proxy/create-jwt-session-resolver-worker-proxy.test.ts
• 3.4 src/proxy/create-jwt-session-resolver-worker-proxy.spec-conformance.test.ts — runAuthSessionConformance("jwt-worker-proxy", ...)
• 3.5 src/jwks/jwks-cache.test.ts
• 3.6 src/claim-mapping/default-claim-to-principal.test.ts
• 3.7 src/security-scheme/security-scheme-contribution.test.ts
• 3.8 tests/integration/integration.test.ts
• 3.9 Every it(...) carries { timeout: 5000 } (30000 if genuinely async)

4. Documentation

• 4.1 Sibling .md per implementation .ts (≥200 words, basic + advanced)
• 4.2 README links co-located .md files
• 4.3 Document the pair-with-IdP usage pattern (Clerk/Auth0/Cognito)

5. Pre-archive verification (5-gate triple)

• 5.1 bun run check — clean
• 5.2 bunx turbo lint typecheck test --filter=@suaveplan/api-auth-jwt — green
• 5.3 bunx turbo test:coverage --filter=@suaveplan/api-auth-jwt — 100/100/100/100
• 5.4 bun scripts/openspec-conformance.ts @suaveplan/api-auth-jwt — exit 0
• 5.5 bunx turbo build --filter=@suaveplan/api-auth-jwt — green

6. Pre-archive 7-row checklist

• 6.1 Generics on AuthAdapter signature; expectTypeOf assertions on Principal projection
• 6.2 Zod schema at the JwtSessionResolverOptions boundary
• 6.3 Every AUTH_JWT_* code thrown by at least one production path
• 6.4 Strict-mode behaviors (audience/issuer required vs optional) tested both on and off
• 6.5 OTel instruments (api.auth.resolve_duration_ms, api.auth.failures_total{reason}) asserted with in-memory MeterProvider
• 6.6 JWKS in-flight refresh dedup tested (concurrent kid misses → one network fetch)
• 6.7 No retroactive tick

7. Archive

• 7.1 Fold into openspec/specs/api-auth-jwt/spec.md
• 7.2 Move to openspec/archive/<yyyy-mm-dd>-api-auth-jwt/
• 7.3 Tick Stage 4 box in umbrella tasks
• 7.4 Refresh MANIFEST.md
