"""Extract-lane artifact: full git commit-history table for /root/troupe-standup.

- 2026-10-25-git-history.csv (rank, hash, short, name, email, date, subject, files)

|
- 2026-10-25-git-history.md (human table, top 50 + statistics)

|
- 2026-10-25-git-history.json (structured, machine-readable)

- CHECK (independent re-derivation gate)

Source of truth: live `git -C /root/troupe-standup log` (current branch main).
