The access check, the admin/creator/current-assignee permission rule,
unassign/assign, the audit log, the optional Matrix assignment
notification and the stats-cache invalidation move into
services/AssignmentService.php for reuse by the MCP assign_ticket tool.
Error messages and status codes are unchanged.
One deliberate difference: assign_ticket.php's early error responses
(400/403/404) used a bare echo and so omitted the CSRF token that
bootstrap had just rotated. Every response now goes through
apiRespond(), which includes it. The front end already resyncs its
token from any response body, so this is compatible, and a failed
assign can no longer leave the page holding a stale token.
Verified over real HTTP: the assignee can reassign (200); a user who can
see the ticket but isn't admin/creator/assignee gets 403 'Permission
denied'.
