requires the negative-cache license feature

The negative cache holds negative results, such as “user not found” or “refused by moderation”, usually with a short TTL, so repeated lookups for the same missing or refused item do not reach your backend or model again. NCACHE.LIST returns the names of all namespaces on the server you are connected to, in no particular order. In a cluster, each node lists only the namespaces it holds.
