 ## Notes
 
-> To be filled by implementation agent
+Validated all acceptance criteria. No changes were needed — the existing configuration is correct.
+
+### Validation Results
+
+1. **`npm run build` produces correct output** ✅
+   - `src/index.ts` → `dist/index.js` (ESM), `dist/index.cjs` (CJS), `dist/index.d.ts` + `dist/index.d.cts` (declarations)
+   - `src/event-target-redis.ts` → `dist/event-target-redis.js` (ESM), `dist/event-target-redis.cjs` (CJS), `dist/event-target-redis.d.ts` + `dist/event-target-redis.d.cts` (declarations)
+   - Code splitting enabled: shared chunk between entries (`chunk-JGLUDY7D.js` / `chunk-TBKAZXTS.cjs`)
+   - Verified both ESM dynamic import and CJS require work for both entry points
+
+2. **`npm run lint` (tsc --noEmit) passes** ✅ — No errors
+
+3. **`package.json` exports map has correct ESM/CJS/dts paths** ✅
+   - `"."` → import (d.ts + js) / require (d.cts + cjs)
+   - `"./event-target-redis"` → import (d.ts + js) / require (d.cts + cjs)
+   - All paths resolve to actual built files
+
+4. **`tsup.config.ts` lists all current entry points** ✅
+   - `src/index.ts` and `src/event-target-redis.ts` both present
+   - `format: ['esm', 'cjs']`, `dts: true`, `splitting: true`, `target: 'es2022'`
+
+5. **`src/index.ts` re-exports everything from all modules** ✅
+   - Exports from: `create_pubsub.js`, `types.js`, `operators.js`, `repeater.js`, `event-target-redis.js`
+   - All public API surface is accessible from barrel
+
+6. **Peer dependencies and peerDependenciesMeta are correct** ✅
+   - `ioredis@^5.0.0` as optional peer dep
+   - Future: `@rayhanadev/iroh` will follow same pattern when added
+
+7. **No runtime dependencies** ✅
+   - `dependencies: {}` is empty
+   - `@repeaterjs/repeater` is inlined in `src/repeater.ts`
+
+### Verified type resolution
+- `import { createRedisEventTarget } from '@alkdev/pubsub/event-target-redis'` — types resolve correctly
+- `import { createPubSub, type EventEnvelope } from '@alkdev/pubsub'` — types resolve correctly
+- Works with both `skipLibCheck: true` and `skipLibCheck: false`
+
+### Verified package contents
+- `npm pack --dry-run` shows 19 files (all dist files + package.json)
+- `files: ["dist"]` correctly includes all build output
 
 ## Summary
 
-> To be filled on completion
+Validated build pipeline, package.json exports map, and tsup config for all adapters. All acceptance criteria pass with no changes required — the existing configuration is correct and consistent.
