Separate arrival correction from booking status
Synthetic session accepts arrival before 18:15. A staff entry says 18:18, but an accepted door register proves 18:12. The booking is already marked attended after review and consumes one session regardless of lateness. Correct the time and late-arrival label; do not add another attendance or reverse ordinary usage.
| Field | Original | Evidence / decision | Corrected |
|---|---|---|---|
| Arrival time | 18:18 | Door register DR-1 | 18:12 |
| Arrival classification | Late | 18:12 is before 18:15 | Within window |
| Consumed sessions | 1 | Attendance remains established | 1 |
Amend the evidence-bearing fields
- Compare accepted evidence with the recorded arrival time.
- Save old/new timestamps, evidence reference and staff reason.
- Recalculate the late label while keeping the existing attendance and consumption.
If a separate penalty depends on lateness, review that specific entry; the one-session example makes no penalty claim.
How far before the cutoff is the corrected arrival?
Show the worked answer
Three minutes before 18:15. It changes late to within-window; session usage remains one.
Corrections should appear as corrections in staff history, while attendance totals count the booking once.
