Validation report

Task 05 integration was performed against the common base and the Task 01-04 outputs were reconciled into one transport/state/UI pipeline.

Final checks

Validation was rerun in GitHub Actions on Node.js 22 with a network-enabled npm environment.

• dependency installation: PASS (npm install --no-audit --no-fund)
• npm run typecheck: PASS
• npm test: PASS — 10 test files, 37 tests
• npm run build: PASS
• V0 runtime policy remains read-only (sandboxMode: read-only, approvalPolicy: never, network disabled)
• app-server smoke verification: PASS (item/started -> multiple item/agentMessage/delta -> item/completed -> turn/completed)
• documented authentication path reuses the host Codex/ChatGPT login; OPENAI_API_KEY is not required for that subscription-auth path

Integration defects fixed during final validation

1. Removed deprecated TypeScript baseUrl; the ~/* path mapping remains relative to tsconfig.json.
2. Moved the client-importable TanStack createServerFn definition from chat.server.ts to chat.ts. This allows TanStack Start to generate the client RPC bridge while keeping the actual Codex runtime in *.server.ts modules.
3. Migrated createServerFn().inputValidator() to createServerFn().validator().
4. Fixed CI so repositories without a committed npm lockfile do not fail during setup-node cache initialization.

The successful CI run validates installation, type checking, the full unit/integration test suite, and the production bundle.
