Arrival and check-in corrections
Resolve arrival windows, wrong-session records and unmatched attendees with evidence.
Apply early and late check-in boundaries
Use one explicit arrival window and route out-of-window arrivals without inventing attendance.
Move a check-in recorded against the wrong session
Verify the attendee’s actual booking before moving attendance and any linked settlement.
Correct an arrival time without changing attendance twice
Record an evidenced timestamp correction and re-evaluate only the rule that depends on that time.
Resolve an arrival with no matching booking
Distinguish a mistaken identity, wrong session and genuine walk-in before creating attendance.
