Tasks — @suaveplan/api-tenant-resolver-header

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 (§6 step 4)
• 1.2 Read openspec/AGENTS.md Sections 13 and 14
• 1.3 Draft proposal.md
• 1.4 Draft specs/api-tenant-resolver-header/spec.md
• 1.5 Every requirement carries **Verified by:**

2. Implementation

• 2.1 Scaffold packages/api-stack/api/api-tenant-resolver-header/
• 2.2 src/resolver/ — createHeaderTenantResolver
• 2.3 src/trust/ — trusted-source enforcement
• 2.4 src/validate/ — default validator + custom validator support
• 2.5 src/error-codes.ts
• 2.6 src/index.ts — explicit named re-exports

3. Tests

• 3.1 src/resolver/resolver.test.ts
• 3.2 src/trust/trust.test.ts
• 3.3 src/resolver/resolver.spec-conformance.test.ts
• 3.4 tests/dep-graph.test.ts
• 3.5 Every it(...) carries { timeout: 5000 }

4. Documentation

• 4.1 Sibling .md per implementation .ts
• 4.2 README.md ## Modules
• 4.3 Update CLAUDE.md package listing — deferred per orchestrator instruction ("Do not edit CLAUDE.md")

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

• 5.1 bunx biome check --write clean
• 5.2 bunx turbo lint typecheck test --filter=@suaveplan/api-tenant-resolver-header — green (62 tests)
• 5.3 bunx turbo test:coverage --filter=@suaveplan/api-tenant-resolver-header — 100/100/100/100
• 5.4 bun scripts/openspec-conformance.ts @suaveplan/api-tenant-resolver-header — script's findPackageDir does not yet support the 3-level packages/<category>/<plugin>/<pkg>/ layout (same failure mode as sibling api-tenant-resolver-jwt); repo-wide tooling bug, unrelated to this package.
• 5.5 bunx turbo build --filter=@suaveplan/api-tenant-resolver-header — green (dist emitted)

6. Pre-archive 7-row checklist

• 6.1 Generics threaded — N/A (no generics)
• 6.2 Zod schemas wired at host-config ingestion (parseHeaderTenantResolverOptions)
• 6.3 Every TENANT_HEADER_* code thrown by a production path (verified by resolver tests + options tests)
• 6.4 Strict-mode: invalid header → 400 in strict, → null in non-strict (verified by strict mode raises 400 on invalid + non-strict mode returns null on invalid)
• 6.5 OTel api.tenant.resolves_total{resolver="header"} asserted (verified by well-formed header resolves + emits exactly one counter increment per resolve() call)
• 6.6 Lifecycle dedup — resolver is pure / idempotent (no module state; verified by concurrent-call test in spec-conformance)
• 6.7 No retroactive tick

7. Archive

• 7.1 Fold spec delta into openspec/specs/api-tenant-resolver-header/spec.md
• 7.2 Move folder to archive
• 7.3 Tick 8.15 in umbrella tasks
• 7.4 Refresh MANIFEST.md
