+    WARN: bash mutation command (git commit/push/mv/rm/reset/merge/revert,
+    sed -i, or gh pr create/merge/edit) detected without a leading
+    `cd /<path>` prefix.
+
+    Per feedback_cd_between_worktrees.md: when working across multiple
+    parallel git worktrees in the same session, EVERY bash invocation that
+    touches a specific worktree MUST start with explicit
+    `cd /full/path/to/worktree && ...`.
+
+    Bug pattern this prevents (real, 2026-05-10):
+    - Two parallel worktrees for two PRs (PR-2 + PR-3 of same repo).
+    - First worktree's sed + commit + push: correct (cwd was PR-2).
+    - Second worktree's sed + commit + push: missing cd → still in PR-2 cwd
+      → commit landed on PR-2 branch instead of PR-3 branch.
+    - Required revert on PR-2 + correct re-apply on PR-3. Confused commit
+      history visible to reviewers.
+
+    If the command operates on absolute paths or doesn't need cwd context,
+    or you've intentionally verified cwd via `pwd` immediately before,
+    add "# hook-bypass: cd-worktree-rule" to acknowledge.
