Checks run on a task-owned Blacksmith testbox at PR head:
$ vp test run packages/provider-pi/src/server/adapter.test.ts
1 test file passed; 128 tests passed.
$ vp run --filter @t3tools/provider-pi typecheck
exit 0 (two pre-existing schema-brand suggestions).

Real app path: Playwright from repository dependencies + /usr/bin/google-chrome -> Vite dev app -> T3 WebSocket/orchestration -> real Pi 1.5.1 subprocess -> local proxy -> gpt-6.1-sol.
The project and all threads/turns were created through the app. No provider events were mocked or replayed.
Pi launch arguments for both successful baseline and PR runs:
--approve --no-extensions --no-mcp --extension /home/user/verification-repo/.pi/extensions/redact.ts
The explicit extension uses Pi message_end replacement to redact PRIVATE-32440 from real assistant text and append a new text block. T3 still injects its own provider permission/MCP bridge.
