# Tasks: enterprise-web-workers

## Scaffolding

- [x] Add `web-workers` to `data:` plugin in `scripts/folder-reorg/assignment.yml`.
- [x] Create `packages/foundation/data/web-workers/` skeleton (`package.json`, `README.md`, `tsconfig.lib.json`, `vite.config.ts`, `vitest.config.ts`).
- [x] Wire workspace catalog deps: `@suaveplan/error`, `@suaveplan/events`, `@suaveplan/opentelemetry`, `@suaveplan/types`, `tslib`, `@opentelemetry/api`.

## Implementation

- [x] `errors/errors.ts` — `WEB_WORKERS_CODES`, `WebWorkersError`, metadata table.
- [x] `types/web-workers.types.ts` — public type surface.
- [x] `observability/observability.ts` + `observability.types.ts`.
- [x] `helpers/define-worker.ts` — `defineWorker({ url, type })` returns `WorkerFactory`.
- [x] `circuit-breaker/circuit-breaker.ts` — per-worker breaker.
- [x] `base-manager/base-manager.ts` + `base-manager.types.ts` — shared lifecycle, RPC pending map, AbortSignal, transfer, backpressure, breaker, OTel emission, `EventBus` wiring.
- [x] `worker-manager/worker-manager.ts` — classic-Worker concrete manager.
- [x] `shared-worker-manager/shared-worker-manager.ts` — `SharedWorker` port-per-client concrete manager.
- [x] `streaming/stream.ts` — `sendStream` async-iterable RPC.
- [x] `worker-pool/scheduler.ts` — round-robin + least-busy.
- [x] `worker-pool/worker-pool.ts` — FIFO queue, scheduler, restart-on-crash, health probe.
- [x] `message-bus/message-bus.ts` — pub/sub + once + broadcast + registerHandler + request (with timeout + AbortSignal).
- [x] `index.ts` — explicit named re-exports (rule 10).

## Documentation

- [x] Sibling `.md` next to every `.ts` per CLAUDE rule (≥200 words, 6 sections).
- [x] Root `README.md` with quick-start + module links.

## Gates

- [x] `bunx turbo lint typecheck test build --filter=@suaveplan/web-workers` green.
- [x] `bunx turbo test:coverage --filter=@suaveplan/web-workers` ≥ 100/100/100/100.
- [x] `bun scripts/folder-reorg/generate-manifest.ts` (refresh MANIFEST).

## Finalisation

- [x] Fold `specs/web-workers/spec.md` into `openspec/specs/web-workers/spec.md`.
- [x] Move change to `openspec/archive/2026-05-25-enterprise-web-workers/`.
- [x] Flip `STATUS.md` row from `–` to `✅` and bump counts.
- [x] Commit on `feat/migrate-web-workers` with Conventional Commit + Claude co-author footer (do not push).
