Evidence for issue 35510
Real Linux server and dev runner, fresh synthetic state, no providers invoked.
The Tailscale executable is a stand-in, not a live HTTPS-disabled tailnet.
Run each driver: python3 DRIVER.py OUTPUT_DIRECTORY BASE_CHECKOUT HEAD_CHECKOUT
Install dependencies in both checkouts with vp i first.
Videos render the timestamped captured server output and driver observations at original elapsed time; unrelated startup output is omitted to protect local metadata. PNGs are final transcript frames, not browser screenshots.
Exit-zero server observation: 68 seconds per case. Flushed-notice blocking comparison: 22 seconds per case. Dev sharing: 22 seconds per case; ports derive from checkout paths.
The final serve-status query is from the driver. Earlier calls are from the app.
AI-assisted; verified with the tests and tools listed above.
