Nabu — the trusted investigation & discovery platform — is customised for a client by selection, not by rewrite: which roles the matter needs, which checks the work needs, and which models the domain needs. Three services supply them, and every one leaves its stamp in the custody record.
Ummânu and Kulla are services that enrich a Nabu implementation. Personas staff the agents; promoted skills tool the gates; both are stamped into the custody record of everything they touch.
