 ## Notes
 
-> To be filled by implementation agent
+### Final Review Report
+
+**Build**: All 5 entry points produce correct ESM + CJS + declarations. tsup with splitting produces shared chunks correctly.
+
+**Lint**: `tsc --noEmit` passes cleanly.
+
+**Tests**: 242 tests across 8 files, all passing.
+
+**Coverage**:
+- `create_pubsub.ts`: 100% (all)
+- `operators.ts`: 100% (all)
+- `event-target-redis.ts`: 97.36%
+- `event-target-websocket-client.ts`: 97.75%
+- `event-target-websocket-server.ts`: 92.44%
+- `event-target-worker.ts`: 51.26% (thread side untested — requires Worker env)
+- `index.ts` / `types.ts`: 0% (barrel/type-only, expected)
+- `repeater.ts`: 67.35% (inlined, complex async iterator)
+- Overall: 81.99% statements, core modules > 90%
+
+**Sub-path exports**: All 4 adapters have correct exports in package.json (ESM + CJS + d.ts + d.cts), tsup config entries, and barrel re-exports in index.ts.
+
+**No runtime dependencies**: Confirmed. `dependencies` is `{}`. Repeater is inlined. `ioredis` is optional peer dep.
+
+**Package consumption**: All sub-path imports resolve correctly:
+- `@alkdev/pubsub` → core + operators + all adapters
+- `@alkdev/pubsub/event-target-redis` → Redis adapter
+- `@alkdev/pubsub/event-target-websocket-client` → WS client
+- `@alkdev/pubsub/event-target-websocket-server` → WS server
+- `@alkdev/pubsub/event-target-worker` → Worker adapter
