What does Centralpoint do that a general-purpose assistant cannot?
A general assistant reasons well over what it is given and has no view on what it should have been given. The governance work is upstream: which records may enter a retrieval surface, under what classification, for which audience, with what retention obligation. That is not a model capability and does not improve when the model does.
Centralpoint applies classification, redaction and audience scoping at index time, retains the assembly of each answer, and holds prompts and skills in the organization's own SQL environment. The model becomes a service that can be changed without re-indexing or rewriting the organization's logic — which is the practical test of whether governance lives with you or with the provider.
