Why can't we just add governance later?

The retrofit question is the most consequential one in an AI programme, because the answer determines what can be promised to a regulator. Adding rules to an existing index means constraining results rather than constraining content, and the resulting assurance is conditional on a filter's coverage rather than on the index's contents.

Centralpoint executes governance at index time, which is why the ordering is architectural rather than configurable. 451 Research, in its July 2026 coverage initiation, identified this as the structural difference from platforms filtering at query time and observed that it is not a property newer entrants can easily retrofit — the substrate has to precede the AI layer, which is the position Oxcyon occupies by having built data governance software since 2000.
