  timeout 60 git fetch github refs/pull/23654/head
  git switch --detach FETCH_HEAD

An initial root-checkout launch defaulted to ~/.t3; stopped immediately before verification actions.
Restarted with explicit isolated home:
  setsid nohup vp run dev --home-dir /home/user/t3code/.t3 --no-seed > /tmp/dev.log 2>&1 &
  captured process group leader: 23955
  dev-runner: serverPort=13773 webPort=5733 baseDir=/home/user/t3code/.t3
Created the real git project through the web app. No seeded data.
Codex gpt-6.1-sol first turn -> PR_CODEX_OK.
Same thread follow-up asking for previously supplied word -> copper.
Reloaded client and reopened thread -> both replies persisted.
Added Antigravity and installed official 1.3.0 through Settings.
Observed native command line:
  agy_acp_server.par --uid= --alsologtostderr
Sign in -> native runtime supplied Google authorization URL; UI showed Open browser and Cancel.
Cancel sign-in -> Retry sign-in. Retried -> Google authorization again. Cancelled again successfully.
No Google account authorization was completed. No Antigravity agent turn ran.

Remote focused checks (blacksmith-check, dependencies installed with vp i):
  vp test run apps/server/src/provider/antigravityAuthSupport.test.ts apps/server/src/orchestration-v2/Adapters/AntigravityAdapterV2.test.ts apps/server/src/orchestration-v2/Adapters/AcpAdapterV2.test.ts apps/server/src/provider/Drivers/AntigravityDriver.test.ts
Result: 4 files passed, 108 tests passed.
These include existing subprocess mocks and do NOT prove authenticated live recovery.
Task-owned Blacksmith worker stopped.

Not verified: original failure on main, real Antigravity harness failure detection, fresh-process resume of same native session, shared ACP cancel-timeout retirement in a signed-in turn, native desktop/mobile, macOS/Windows, remote/relay/tunnel.
