# Check-in ledger census — 2026-09-24 .. 2026-10-21

One row per `checkins/YYYY-MM-DD-<wizard>.md` file. Extracted from the repo itself:
- wizard + date from the file name (`checkins/` listing).
- size_bytes from `os.path.getsize`.
- commits_touching from `git log --oneline -- checkins/<file> | wc -l`.
- same_date_reply: at least one file in `replies/` whose name is `<date>-to-<wizard>*`.
