Two Hands were dispatched into one working tree. The second switched the
branch out from under the first's running build, then found an uncommitted
edit it had not made and stopped rather than forcing the checkout. Nothing was
lost because of that refusal, not because of anything Self did.
The rule was already written and Self ignored it, so the fix is not a louder
warning to Hands. A brief that names a repo path without naming a worktree is
a defect in the brief.
