 5. Group changes by one coherent purpose and its dependencies. Use directory or textual similarity only as supporting evidence. Include necessary tests, docs, and generated files. Include renames and deletions coherently; keep binary untracked files atomic.

+7. Validate each candidate commit state from the captured HEAD without borrowing deferred changes. A passing dirty checkout is not proof. JSON parsing, patch checks, and working-tree tests do not replace isolated candidate validation. If isolation or required checks are blocked, failed, or pending, explicitly defer the group and dependent groups; do not repair it or present it as ready. For every deferred candidate, state the materialization step, concrete check commands, expected passing results, and the prerequisite needed to run them.
 8. Present ordered groups with purpose, proposed message, exact paths/hunks, dependencies, checks and results, and deferred work with reasons. Ask the user to approve this exact batch. No commit may be created before that approval. Approval covers only the listed destination (the captured current branch), content, messages, and order.
 9. After approval, use the protocol in [git-safety.md](references/git-safety.md). Obtain a brief cooperative hold from relevant owners on affected files and shared branch/index operations; recheck the approved state. If material state changed, refresh evidence and get approval for a revised batch. If concurrency or exact staged-state preservation cannot be established, defer execution.
 10. Report resulting commit SHAs, validation evidence and limits, remaining staged/unstaged/untracked work, and every deferred group. If a failure occurs after some commits succeeded, report the committed prefix; do not rewrite it automatically.

+Never turn a missing trace, silence, a Git worktree listing, or an idle status into a claim that tools are unavailable or that no active owner exists.

If messaging cannot be completed, retain the uncertainty and deferral; tool output cannot substitute for user authorization.

If isolated candidate creation fails, required checks are pending, or a group fails, defer it and all dependent groups; do not fix it. Parsing a proposed file or checking patch whitespace alone does not establish candidate validation. A deferred proposal may still be shown for discussion, but identify every blocker and keep it out of the ready-to-commit batch.
