2026-10-03, system-steward seat. query_my_tasks / query_my_role called with no arguments returns JSON-RPC -32602 'Required parameter seat'. With seat=system-steward, query_my_role returned total:0 - not because the role was missing but because the seat had no access to Directory, where the profile lives (fixed c46c595, then 2 rows). An empty security-trimmed list looks exactly like an empty list; when a seat's own data reads empty, check its grants before concluding nothing is there.
