Summary

Concurrent scripts/pr operations for the same pull request run without a shared operation lock and can mutate the same worktree and review/prepare/merge artifacts at the same time.

Steps to reproduce

1. Start a long-running state-changing scripts/pr command for a pull request, such as review validation or prepare gates.
2. Before it finishes, run another state-changing scripts/pr command for the same pull request from another terminal or worktree.
3. Observe that the second command starts instead of waiting for the first command to finish.

Expected behavior

State-changing scripts/pr commands for one pull request serialize across all linked worktrees. Commands for different pull requests remain independent. Interrupted or indeterminate ownership fails closed and requires explicit recovery.

Actual behavior

Each invocation independently enters and mutates the same .worktrees/pr-N checkout and .local artifact namespace. Worktree garbage collection can also inspect or remove a pull-request worktree while another scripts/pr operation is using it.

Logs

The current wrapper has no cross-process or cross-worktree same-PR serialization boundary.

Impact and severity

• Affected: maintainers running review, prepare, merge, or garbage-collection workflows concurrently.
• Severity: high for the affected workflow because competing commands can invalidate evidence or mutate/remove a shared worktree.
• Frequency: deterministic whenever same-PR operations overlap; overlap itself is intermittent.
• Consequence: unreliable landing evidence, failed commands, or conflicting worktree state.

Additional information

The desired boundary is per pull request rather than repository-wide so unrelated pull requests can still progress concurrently.
