-Where an operation stacks several requirements, Fluxer evaluates each separately and the caller must satisfy all of them. [Create NCMEC report](/admin-api/messages/#create-ncmec-report) is the widest example and stacks `csam:submit_ncmec`, `message:delete`, `user:delete`, and `archive:trigger:user` as independent requirements.

[List users](/admin-api/users/#list-users) is one example and stacks `user:view:email` or `user:view:ip` on top of `user:lookup` when a request uses a selector that needs one.
 
 The effective ACL set of a session or an Admin OAuth2 bearer credential is the set stored on the account.

 Fluxer checks each ACL an Admin grants against the ACLs that Admin holds. [Set user ACLs](/admin-api/users/#set-user-acls) and [Create Admin API key](/admin-api/api-keys/#create-admin-api-key) both refuse to write an ACL the acting Admin does not itself hold, with 403 `MISSING_ACL`. A wildcard holder is exempt. Set user ACLs also refuses the acting Admin's own account with 403 `ACCESS_DENIED`, and it looks up the target account before it checks the granted ACLs, so an unknown ID fails first with 404 `UNKNOWN_USER`.
