Additional reproduction and diagnostics from another Windows 11 user:
Environment
- OS: Windows 11 25H2
- T3 Code: 0.0.39-nightly.20260903.1272 (d5825e1)
- Antigravity provider: managed runtime installed by T3 Code
- Managed ACP runtime: agy_acp_server_20260818_01_RC01
- Browser: Vivaldi, registered as the default HTTP/HTTPS browser
Reproduction
- Enable Antigravity in Settings > Providers.
- Install the managed Antigravity runtime.
- Click Sign in with Google / Retry Google sign-in.
- No browser window opens.
- The UI does not show Open sign-in page or Copy sign-in link.
- After waiting, authentication fails.
Observed diagnostics
The managed runtime starts and ACP initialization succeeds. During the sign-in attempt, T3 records successful:
- ProviderAuthService.start
- ws.rpc.provider.auth.start
- antigravityAuthSupport.handleStdoutLine
- offerOutgoing
However, no external browser launch is recorded and no complete authentication URL is exposed in the server or desktop logs. The local ACP authentication endpoint on 127.0.0.1 returns:
Authentication failed
After approximately three minutes, T3 fails with:
Error: Onboarding failed: The authentication flow did not complete successfully.
The local agy.exe CLI is installed and runs, but it does not expose an agy login subcommand. Signing in through the CLI/IDE is not a workaround because the T3-managed Antigravity provider keeps its own credentials.
Suspected failure
The ACP server appears to emit/process the Google authentication URL, but the URL is lost between the T3 server outgoing event and the desktop/web provider UI. The expected Open sign-in page / Copy sign-in link fallback is never rendered, so the callback cannot be completed.
Please investigate the Antigravity ACP auth URL handoff from handleStdoutLine / offerOutgoing to the provider UI and browser-opening fallback.
