# Tasks — add-packer-browser-core (Cluster A migration of `@suaveplan/packer-browser`)
|
|
|
|
> Every checkbox MUST reflect work actually done in this change. No retroactive ticking.
|
|
|
|
## 1. Spec authoring
|
|
|
|
- [x] 1.1 Read `../suaveplan/enterprise/packer-browser.md` end-to-end
|
|
- [x] 1.2 Read `openspec/specs/packer/spec.md` (sibling reference) and the
|
|
archived `enterprise-packer-*` change deltas
|
|
- [x] 1.3 Read `openspec/AGENTS.md` §0a, §0c, §2b, §2c, §6a, §7, §13, §14
|
|
- [x] 1.4 Draft `proposal.md` from `openspec/templates/proposal.md` with
|
|
`## Source mapping`, `## Out of scope`, `## Parity Checklist`, and
|
|
`## Impact` populated
|
|
- [x] 1.5 Fill in `## Source mapping` table — every requirement cites
|
|
enterprise-audit line ranges OR appears in the "no source line" table
|
|
- [x] 1.6 Draft `specs/packer-browser/spec.md` from
|
|
`openspec/templates/spec-delta.md`
|
|
- [x] 1.7 Every requirement in the spec delta carries a `**Verified by:**`
|
|
line naming concrete `it(...)` titles
|
|
|
|
## 2. Implementation
|
|
|
|
- [x] 2.1 Fix `scripts/folder-reorg/assignment.yml` — remove
|
|
`- packer-browser` from `bitpacker:`, insert under `data:` between
|
|
`packer` and `pagination`
|
|
- [x] 2.2 Author `package.json` (workspace deps via `workspace:^`,
|
|
externals via `catalog:` keys, no React, no bare versions)
|
|
- [x] 2.3 Author `tsconfig.lib.json` (extends repo base, DOM + WebWorker
|
|
libs)
|
|
- [x] 2.4 Author `vite.config.ts` (multi-entry build for the 5 subpaths)
|
|
- [x] 2.5 Author `vitest.config.ts` (via `createTestConfig` with
|
|
`happy-dom`, `fileParallelism: false`)
|
|
- [x] 2.6 Author `playwright.config.ts` (Chromium project, no parallelism)
|
|
- [x] 2.7 `src/error-codes.ts` — `PACKER_BROWSER_CODES` (6 stable codes) +
|
|
`PACKER_BROWSER_ERROR_METADATA` + `PackerBrowserError extends SuaveplanError`
|
|
- [x] 2.8 `src/i18n/messages.ts` + `messages.types.ts` — `PACKER_BROWSER_MESSAGES`
|
|
catalog + `defaultPackerBrowserResolver` + `resolvePackerBrowserMessage`
|
|
- [x] 2.9 `src/runtime/runtime.ts` + `runtime.types.ts` — `defaultClock`,
|
|
`defaultRng`, `resolveRuntime`, `elapsedMs`
|
|
- [x] 2.10 `src/observability/observability.ts` + `observability.types.ts`
|
|
— `createPackerBrowserObservability` exposing 3 counters + 1 histogram
|
|
- [x] 2.11 `src/flags/flags.ts` — `resolveFlagsProvider` (`MemoryProvider`
|
|
fallback)
|
|
- [x] 2.12 `src/signature/signature.ts` — `verifyArchiveSignature` wrapping
|
|
`ed25519.verify`
|
|
- [x] 2.13 `src/cache/cache.ts` — `PackedResourceCache` (LRU + ref-count +
|
|
Blob-URL bookkeeping, OTel-instrumented, Clock-driven timestamps)
|
|
- [x] 2.14 `src/loader/loader.ts` — `PackedResourceLoader` (fetch via
|
|
`withRetry`, signature verification, `AbortSignal` at every yield,
|
|
`Unpacker.unpack` integration, histogram observation)
|
|
- [x] 2.15 `src/manager/manager.ts` — `PackedResourceManager` lifecycle
|
|
façade + `createPackedResourceManager` factory + event emitter; each
|
|
file ≤ 300 LOC
|
|
- [x] 2.16 `src/service-worker/sw-shim.ts` — hand-rolled
|
|
`createServiceWorkerShim()` implementing `ServiceWorkerGlobalScope`,
|
|
`FetchEvent`, `ExtendableEvent`, `Cache`, `CacheStorage`, `Clients`
|
|
- [x] 2.17 `src/service-worker/service-worker.ts` —
|
|
`runPackedResourceServiceWorker(scope)` registering install / activate /
|
|
fetch / message handlers
|
|
- [x] 2.18 `src/utils/register-service-worker.ts` — register / unregister /
|
|
clearCache / getCacheStatus helpers
|
|
- [x] 2.19 `src/singleton.ts` — module-singleton hosted at `/singleton`
|
|
subpath
|
|
- [x] 2.20 `src/index.ts` — explicit named re-exports (no `export *`);
|
|
default surface excludes `packedResourceManager`
|
|
- [x] 2.21 `README.md` — install / quick-start / modules
|
|
|
|

|
## 4. Documentation
|
|
|
|

|
|
Purpose / Features / Basic / Advanced / API Reference /
|
|
Implementation Notes)
|
|

|
|
- [x] 4.3 Update root `CLAUDE.md` package listing to add the new package
|
|

|
|
move it into the `data` section table
|
|
- [x] 4.5 Refresh `MANIFEST.md` via
|
|
`bun scripts/folder-reorg/generate-manifest.ts`
|
|
|
|
## 5. Pre-archive verification (the 5-gate triple)
|
|
|
|
- [x] 5.1 `bun run check` — Biome 0 errors / 0 warnings / 0 info
|
|
- [x] 5.2 `bunx turbo lint typecheck test --filter=@suaveplan/packer-browser`
|
|
— green
|
|
- [x] 5.3 `bunx turbo test:coverage --filter=@suaveplan/packer-browser` —
|
|
100/100/100/100
|
|
- [x] 5.4 `bun scripts/openspec-conformance.ts @suaveplan/packer-browser`
|
|
— exit 0
|
|

|
|
|
|
## 6. Pre-archive 7-row checklist (AGENTS.md §13)
|
|
|
|
- [x] 6.1 Generics threaded; `expectTypeOf` assertions on every literal-type
|
|
claim that affects the public surface
|
|
- [x] 6.2 Zod schemas wired at every declared boundary (option-bundle
|
|
validation deferred to Cluster B per audit; flagged in proposal)
|
|
- [x] 6.3 Every error code in `error-codes.ts` thrown by at least one
|
|
production path
|
|
- [x] 6.4 Strict-mode behaviors tested both on and off (signature verify
|
|
on / off; retry on / off; cache on / off)
|
|
- [x] 6.5 OTel instruments emitted from production paths and asserted with
|
|
a real in-memory `MeterProvider`
|
|
- [x] 6.6 Lifecycle dedup tested where claimed (factory returns fresh
|
|
instances; singleton returns stable reference)
|
|
- [x] 6.7 No retroactive tick — every box above reflects work done in this
|
|
change
|
|
|
|
## 7. Archive
|
|
|
|
- [x] 7.1 Fold spec delta into `openspec/specs/packer-browser/spec.md`
|
|
- [x] 7.2 Move `openspec/changes/add-packer-browser-core/` →
|
|
`openspec/archive/<yyyy-mm-dd>-add-packer-browser-core/`
|
|
- [x] 7.3 Refresh `MANIFEST.md` after the move
