Children never commit (their prompts forbid git add/commit, overriding
project instructions) so the commit is deterministic. At the phase commit
point (00_phase.md final pass) the harness makes ONE atomic commit: the
phase's code changes, the todo→complete file move, and the executor
reports, together.
- Scoped staging: a worktree snapshot taken at the phase's first unit
(phase-sessions/dirty-<phase>, always kept) is subtracted, so the
owner's pre-existing uncommitted work is left alone; runtime artifacts
are never staged. The commit prints exactly what went in.
- Verified: the moved phase file (and report, unless gitignored) must be
in the index before committing.
- Loud on failure: a commit failure prints the git error + hand-fix and
stops the run; the phase stays complete, the miss is never swept into a
later phase.
- PHASE_COMMIT_SUBJECT (default 'phase: <phase>'); the executor's final
report becomes the commit body; --no-gpg-sign always passed.
- PHASE_COMMIT defaults to 1: completed phases are committed by default.
Explicit PHASE_COMMIT=0 opts out with a loud warning that the phase is
complete but uncommitted — a completed phase is never left uncommitted
silently (that gap let four phases pile up uncommitted in
brain_of_reese).
