Real T3 Code server proof; no unit tests.
Run seed.py in a fresh directory, then serve.py SIDE CHECKOUT PORT and driver.ts SIDE CHECKOUT PORT.
The driver holds a foreground RPC lease for 210 seconds. record.py records a live trace monitor at 1 fps.
The synthetic local repository uses an existing merged PR (35603), with its checked-out-PR marker, to seed the terminal state without changing a public PR.
Only the server transport and storage are real; no provider turn is started. No app source is modified.
Git wrapper forwards every command to /usr/bin/git and records invocations in the synthetic repository.
Trace exports include discovery spans and descendants, with sensitive attributes removed.
Before and after PNGs are stills from the live server monitoring capture, not screenshots of the web client.
