Head: a723fd6c896fd131e08b339b81a2697d668948bc
Baseline: github/main 71646e031a

Both checkouts: vp i; background vp run dev; isolated task state.
Baseline ports: web 8693, server 16733. Stopped before PR startup.
PR ports: web 5733, server 13773; explicit --home-dir /home/user/t3code/.t3.
Browser: repo Playwright 1.60.0, /usr/bin/google-chrome, 1440x1000.

Created projects and threads through the web client. Selected Codex GPT-6.1-Sol.
Baseline real turn: git status --short and separate bounded shell probes completed.
Generated real thread-wait spans through the running server's authenticated MCP API
while a real Codex turn was active. Reset task trace logs to isolate the measurement.
No fabricated trace records, mocked responses, fixtures, or replay provider.

PR real provider turn, via web composer and Codex GPT-6.1-Sol:
$ timeout 10 git status --short
exitCode: 0; no output
$ timeout 10 sh -c "sleep 0.1; printf real-provider-ok"
real-provider-ok
exitCode: 0
Client final response: real provider verified.

Explicit comparison uses the PR's actual parent because the worker has shallow history.
GitCafe status: 31 successful checks, 0 failing, 0 pending.

Unverified: native Electron shell, macOS/Windows, iOS/Android.
Mobile has no Diagnostics view. Linux native resource monitor binary is unavailable;
that baseline limitation does not prevent Trace Diagnostics or real Codex turns.
