    C-01 · Copied log out of sequence

    RULE-DUP-001 · exact match on badge id, door, event code across sources

    E-05 row 7 matches E-04 row 18 on badge, door and event code but is stamped 21:09:00 instead of 21:12:00 — before the first person enters at 21:10:00 (E-01). Possible copy or import error; not proof of tampering.
