Setup: one vp run dev at a time; isolated real peer via t3 serve.
Chrome /usr/bin/google-chrome and repository Playwright 1.60.0.
Real Codex gpt-6.1-sol through the local proxy. No mocked server responses.
A forwarding HTTP proxy stalled only the selected MCP handshake request.
Project and threads created through the web app and t3 application CLI.

main, initialize stalled:
- Real Codex t3_project_list reached proxy at 08:52:48.026Z.
- Browser capture: still Listing projects after 1m39s, no result/error.
- Independent public MCP call aborted by its client after 15001ms without answer.

PR, initialize stalled:
- Public MCP t3_project_list: orchestration_error after 3050ms.
- message: The linked environment stopped answering.
- peerLinks.list: lastError = Operation timed out after 3s.

PR, notifications/initialized stalled:
- Public MCP t3_project_list: same orchestration_error after 3020ms.
- Web composer -> real Codex -> t3_project_list:
  initialize forwarded at 08:57:50.641Z;
  initialized notification stalled at 08:57:50.647Z;
  real Codex reported the expected error; turn completed.

Recovery, normal forwarding restored:
- Public MCP t3_project_list succeeded after 62ms with real project
  handshake verification repo, workspaceRoot /home/user/t3code.
- peerLinks.list: reachable, lastError = null.
- Same Codex thread successfully reported that project title and workspaceRoot.

Long tool call:
- A forwarded t3_thread_wait waited on B running real Codex gpt-6.1-sol.
- B executed timeout 30 sleep 12 and replied second-wait-complete.
- Wait returned status completed, timedOut false after 19620ms.
- No 3s deadline applied to the tool call.
