The Activity Log records every entry, edit, deletion, approval and test in plain language, with login/logout tracking — a complete, admin-only audit trail for accountability.

Every action in the app is logged automatically.
Entries read in plain language with author and time.
Admins review the trail whenever a figure is questioned.
When a figure is questioned, an admin opens the activity log and sees every entry, edit, deletion and approval in plain language, with who and when.
