Codex gpt-6.1-sol, Low. Prompt: Read README.md and reply with its first line. Do not change files.

MAIN: launch new worktree, wait for setup-started and background rename, click Cancel.
$ git -C /home/user/cancel-verification branch -av
* main                        687d67e chore: initialize verification repository
+ t3/read-readme-first-line   687d67e chore: initialize verification repository

$ git -C /home/user/cancel-verification worktree list
/home/user/cancel-verification                                 687d67e [main]
/home/user/main/.t3/worktrees/cancel-verification/t3-b76d7fad  687d67e [t3/read-readme-first-line]
Result: cancelled worktree removed, its renamed branch -1 incorrectly retained.

PR: identical new-worktree launch; setup-started visible; rename completed to -2; click Cancel.
Before: t3/read-readme-first-line-2 checked out at /home/user/t3code/.t3/worktrees/cancel-verification/t3-598c060a
After: branch -2 absent and worktree absent; main and preexisting branches unchanged.

PR: Retry, cancel again during setup. See before.txt/after.txt output below.

PASS: format, lint, knip, graphql, 3-package typecheck, 47 tests in 2 files.
PR CI: 31 successful, 0 failing, 0 pending at inspection.

Not exercised live: submodule checkout cancellation, precisely timed rename race, setup failure rollback,
native mobile/Electron shells, Windows/macOS, relay/tunnel, other providers.
The focused tests cover cancellation ownership and rename cases; no claim of live race coverage.
