Two CodeRabbit findings on PR #2921 (review 4209533909 + comment
3171721073, both still unresolved):
A. Branch switch and create steps now abort on non-zero exit. Previously
`git switch "$BRANCH_NAME"` and `git checkout -b "$BRANCH_NAME"
"origin/$DEFAULT_BRANCH"` could fail (locked worktree, dirty tree
refusing the checkout, etc.) and the workflow would silently continue
on the wrong branch — sending the phase's later commits to the wrong
place. Both calls now `|| { echo "ERROR: …" >&2; exit 1; }`.
B. The fork-point base-warning is now scoped to the creation arm of
the if/else. Previously it ran for the resume path too, so a
legitimate resumed branch where origin/$DEFAULT_BRANCH had advanced
since first creation would falsely warn ("does not fork from
origin/<DEFAULT_BRANCH>"). Moving the check inside the else arm
means it only runs immediately after a fresh `git checkout -b`, when
the merge-base check is meaningful.
Same fix mirrored in get-shit-done/workflows/quick.md.
execute-phase.md stays at the 1700-line XL budget. Full suite: 6102/6102.
