telekit access add-user <telegram_id> --label "collab" --node appleo --thread default
telekit access grant <telegram_id> <node> --thread default
telekit access revoke <telegram_id> <node>
--profile scopes the grant to one bot. They see only granted nodes. Paths are hidden from members. An ungranted /node payroll reads as “no such node” — telekit does not confirm that the node exists. Thread grants: omit for default, or list slugs, or * for all. /whoami prints the numeric id to give the owner.
