+# Tasks — storage-cdn-rackspace
+
+> Every checkbox MUST reflect work actually done in this change.
+> Hard dependency: `@suaveplan/storage-cdn` (change `add-storage-cdn`) MUST be archived first.
+
+## 1. Spec authoring
+
+- [ ] 1.1 Read `openspec/changes/add-storage-cdn/specs/storage-cdn/spec.md` for the contract
+- [ ] 1.2 Read `openspec/changes/add-storage-http/` for retry/AbortSignal/OTel patterns
+- [ ] 1.3 Read OpenStack Swift API reference + Rackspace identity v2 docs + Swift TempURL middleware spec
+- [ ] 1.4 Draft `proposal.md`, `design.md`, `specs/storage-cdn-rackspace/spec.md`, `tasks.md`
+- [ ] 1.5 Numbered Requirement/Scenario checklist per §0c step 6
+
+## 2. Scaffolding
+
+- [ ] 2.1 Create `packages/storage/storage-cdn-rackspace/`
+- [ ] 2.2 `package.json` v0.0.0, `"sideEffects": false`, subpath exports
+- [ ] 2.3 Deps: `@suaveplan/error`, `@suaveplan/storage`, `@suaveplan/storage-cdn`, `@suaveplan/retry`, `@suaveplan/types`, `@opentelemetry/api`, `zod`, `tslib`
+- [ ] 2.4 DevDeps: `@suaveplan/testing`, `@vitest/coverage-istanbul`, `fast-check`, `mitata`, `typescript`, `vite`, `vite-plugin-dts`, `vitest`
+- [ ] 2.5 `tsconfig`, `vite.config.ts`, `vitest.config.ts` via `createTestConfig`
+
+## 3. Implementation
+
+- [ ] 3.1 `src/error-codes.ts` — `defineCodes("STORAGE_CDN_RACKSPACE", [...])` with 9 codes, `StorageCdnRackspaceError`
+- [ ] 3.2 `src/types/*.ts` + `.schemas.ts` — `RackspaceCdnAdapterOptions` + Zod schema
+- [ ] 3.3 `src/auth-client/auth-client.ts` — v2 identity auth, token cache, service-catalog lookup, proactive refresh
+- [ ] 3.4 `src/cdn-client/cdn-client.ts` — `enableCdn`, `getCdnMetadata`, `purgeObject` with retry
+- [ ] 3.5 `src/temp-url/temp-url.ts` — HMAC-SHA1 TempURL signer via WebCrypto
+- [ ] 3.6 `src/key-sanitizer/key-sanitizer.ts` — strict boundary + per-segment encoder (or import from storage-http if shared)
+- [ ] 3.7 `src/retry-helper/retry-helper.ts` — transient classifier + Retry-After honour
+- [ ] 3.8 `src/otel/otel.ts` — meter/tracer with `provider="rackspace"` + `region` attrs
+- [ ] 3.9 `src/rackspace-cdn-adapter/rackspace-cdn-adapter.ts` — `RackspaceCdnAdapter extends CdnAdapter`
+- [ ] 3.10 `src/registry/registry.ts` — `registerRackspaceCdnProvider()` idempotent
+- [ ] 3.11 `src/index.ts` — explicit named re-exports
+
+## 4. Tests
+
+- [ ] 4.1 `src/auth-client/auth-client.test.ts` — auth round-trip, cache reuse, 401 re-auth, proactive refresh, region resolution, missing region
+- [ ] 4.2 `src/cdn-client/cdn-client.test.ts` — enable, metadata parse, purge 204, purge 429 → PURGE_RATE_LIMITED
+- [ ] 4.3 `src/temp-url/temp-url.test.ts` — reference vector byte-equality, `temp-url-prefix` mode, missing key error
+- [ ] 4.4 `src/key-sanitizer/key-sanitizer.test.ts` — traversal, absolute, overlong, per-segment encoding
+- [ ] 4.5 `src/retry-helper/retry-helper.test.ts` — transient classifier, `Retry-After` honour, non-retry on 401
+- [ ] 4.6 `src/otel/otel.test.ts` — measurement attrs include `provider` and `region`
+- [ ] 4.7 `src/rackspace-cdn-adapter/rackspace-cdn-adapter.test.ts` — full CRUD, range, edgeUrl, purge, signUrl, AbortSignal, retry
+- [ ] 4.8 `src/rackspace-cdn-adapter/rackspace-cdn-adapter.spec-conformance.test.ts` — type conformance, capabilities, every code reachable, tier-purity grep
+- [ ] 4.9 `src/registry/registry.test.ts` — factory dispatch, idempotency
+- [ ] 4.10 Every `it(...)` carries `{ timeout: 5000 }` (or 30000 for genuinely async)
+- [ ] 4.11 All test imports via `@suaveplan/testing/runner` (§7)
+
+## 5. Documentation
+
+- [ ] 5.1 Sibling `.md` for every implementation `.ts`
+- [ ] 5.2 `README.md` documents LON region default, TempURL key rotation guidance, purge rate-limit guidance
+
+## 6. Gates
+
+- [ ] 6.1 `bun run check`
+- [ ] 6.2 `bunx turbo lint typecheck test --filter=@suaveplan/storage-cdn-rackspace`
+- [ ] 6.3 `bunx turbo test:coverage --filter=@suaveplan/storage-cdn-rackspace` (100/100/100/100)
+- [ ] 6.4 `bun scripts/lint/check-test-runner-imports.ts`
+- [ ] 6.5 Tier-purity grep returns empty
+- [ ] 6.6 `bun scripts/openspec-conformance.ts @suaveplan/storage-cdn-rackspace`
+
+## 7. Manifest & archival
+
+- [ ] 7.1 `bun scripts/folder-reorg/generate-manifest.ts`
+- [ ] 7.2 Update `STATUS.md`
+- [ ] 7.3 Fold `specs/storage-cdn-rackspace/spec.md` → `openspec/specs/storage-cdn-rackspace/spec.md`
+- [ ] 7.4 Move change folder → `openspec/archive/<yyyy-mm-dd>-add-storage-cdn-rackspace/`
