How do I see who changed what (Audit Log)?

From the School Administrator manual, "Audit Log".

Senior Admin only. Go to View Audit Log (/audit-log) for the most recent 200 actions taken within your school — roster edits, admin changes, allowlist changes, and more — each with a timestamp (in your school's time zone, with its abbreviation, e.g. EDT) and who did it, shown as that person's email address. Actions taken by Flux support staff during an approved, time-boxed support session (see Operator Access Requests) are clearly flagged Flux support (operator) alongside that specific staff member's email, never blended in as if they were your own team's action.

Any admin — Junior or Senior — can change a parent's login email from Members (see Members — Parents, Password Resets, and Student Links); that's not restricted to Senior Admins. A Details column on the Audit Log shows exactly what changed for this action (old email → new email), so if a change ever looks wrong, you can see precisely what happened and who made it.
