+# Troupe churn — commit & work inventory
+
+Extracted from live evidence. No claim here is unverified: every number in
+Table A re-derives from `git log --format='%ad|%an' --date=short`; every number
+in Table B re-derives from `os.stat()`/walk over `wizard-work/*`.
+
+- Table A: **commits by author and date** (git history). Total commits: **1211**.
+- Table B: **file count, byte size, newest-file path per wizard-work/<wizard> dir**.
+  Total files: **2153**; total bytes: **86,564,059**.
+- Sources: commits_by_author_day.csv/.json; wizard_inventory.csv/.json.
+- Verification: `CHECK` (bash), which re-derives Table A and Table B from the live
+  repo and exits 0 only when the committed tables match.
