Payroll corrections via compensating events

How Corrections Work

PeopleOS uses an event-sourced architecture. When a payroll correction is needed after approval:

1. The original payroll event remains immutable in the ledger
2. A new "compensating event" is created that reverses the original amounts
3. A corrected event is appended with the right values

This preserves a complete audit trail — auditors can see exactly what was originally calculated, when the correction was made, and by whom.
