Foundation for the coupled-capitalize invariant (Frame 2): commit ONLY
.claude/memory + .claude/tasks, never `git add -A`. Safety lives in the
pathspec because automation removes the human diff review.
Proven on real git behavior, not assumed:
- T1/T2: dangling code (untracked or pre-staged) never embarked.
- T2-bis: `git commit -- pathspec` takes the working tree, not a stale index.
- T3 idempotent, T4 fail-closed on broken state, T5 TODO.md in scope.
_changed_paths filters to paths with real changes: `git commit -- pathspec`
aborts the whole commit on a no-match pathspec (e.g. empty .claude/tasks),
unlike `git add` which tolerates it.
