Web client; Chromium 156; Linux x86_64, 4 KiB pages; 1280 x 800 viewport; light theme. Fresh isolated database for each run; no live data seeded.

The scenario start-app.ts server environment was extended identically on both commits with:
NODE_USE_ENV_PROXY=1
HTTPS_PROXY=http://127.0.0.1:9
NO_PROXY=127.0.0.1,localhost
T3CODE_DEV_SEED=0

This deliberately refuses outbound HTTPS connections while keeping the browser and local RPC available. The app runs from each commit through the development runner. The uploaded scenario drives the real app through Settings > Providers > Add provider > Antigravity > Add instance > Install Antigravity.

Final screenshots on each side were captured twice at least 500 ms apart and were byte-identical. Videos are trimmed to the provider wizard through the final error, excluding initial pairing.
