 ## Notes
 
-> To be filled by implementation agent
+### Review Report
+
+**Build / Lint / Tests**: All pass. 242 tests across 8 files. Build produces correct d.ts for all 5 entry points (index, redis, ws-client, ws-server, worker).
+
+**Worker Adapter API**: Matches architecture spec.
+- `createWorkerHostEventTarget(worker: Worker)` — host side, uses `worker.postMessage`/`worker.onmessage`
+- `createWorkerThreadEventTarget()` — thread side, uses `globalThis.postMessage`/`globalThis.onmessage`
+- Both follow the same `Map<string, Set<EventListener>>` pattern as other adapters
+- `__`-prefixed event types are silently ignored (consistent with WS adapters)
+
+**Exports**: Correct.
+- `tsup.config.ts` has `event-target-worker.ts` entry
+- `package.json` has `./event-target-worker` sub-path export
+- `src/index.ts` re-exports both factory functions
+
+**Test Strategy**: Mock-based (not actual Worker threads). Uses mock `Worker` and `globalThis` objects. 42 tests covering host send/receive, thread send/receive, topic scoping, envelope round-trip, bidirectional communication, error handling.
+
+**Observation**: The thread side sets `globalThis.onmessage` directly, which overwrites any existing handler. This is noted in the architecture doc and acceptable — the adapter takes ownership of the message channel.
+
+**Verdict**: PASS
 
 ## Summary
 
-> To be filled on completion
+Worker adapter review passed. 242 tests, build, lint all clean. API matches architecture spec. Web Worker only per R&D decision. Mock-based test strategy is sound (42 tests).
