-The `sed` patch that sets `detectAndUseProxy=1` in `extension.js` must be **re-applied after every Antigravity update**. The search pattern (`detectAndUseProxy=pe.UNSPECIFIED`) is brittle — if the minified variable name changes from `pe` to something else, the patch silently fails.

-**Fix:** Use a regex-based patch (`detectAndUseProxy=[^;]*` → `detectAndUseProxy=1`) or patch via AST manipulation. Add a post-update hook or version check to warn when the patch is stale.
+**Fixed:** Updated sed to use extended regex `s/detectAndUseProxy=[^,;)]+/detectAndUseProxy=1/g` which matches any value assignment regardless of minified variable names. Still requires re-applying after updates, but the pattern is now resilient to bundler name changes.
