Keep name and identity distinct
Synthetic S20 and S21 both display “Kai”. Attendance evidence ATT1 names participant key P21, which roster maps to S21. Local administration attaches ATT1 to that mapping only. It does not infer competence or attach evidence to everyone sharing the name.
| Reference | Display | Identity |
|---|---|---|
| StaffS20 | Kai | P20 |
| StaffS21 | Kai | P21 |
| ATT1 | Kai | P21 |
Match the participant reference
- Read ATT1 participant key
- Resolve P21 through roster
- Link ATT1 to S21
- Keep S20 evidence unchanged
An attendance file with name only stays unmatched until sufficient identity evidence arrives.

Attach evidence to one person

Preserve participant key and roster revision beside ATT1. Keep the evidence tied to its participant and session identity.
