 ### Fixed
 
 - Creating an event was never recorded in the admin audit log — 1.10.0 added `event_created` as a logged action on the frontend's filter list, but the backend's `createEvent` never actually called `logAdminAction`, only `updateEvent`/`deleteEvent` did. Event creation is now logged the same way.
+- Staff cancelling a registration via `PUT /api/registrations/:id` (the staff status-change endpoint, separate from the owner-facing `DELETE /:id` cancel route) wasn't logged at all — only the `DELETE` path logged `registration_cancelled`. Both paths now log it, verified against all six audit categories promised in 1.10.0 (refunds, donation assign/unassign, manual registrations, staff-initiated cancellations, event create/update/delete, settings changes) with no other gaps found.
 - Added a "Back to dashboard" link to Admin → Audit log, matching the back-link pattern already used on the Cashup page.
