Historical Version Auditing
This is the question litigation and regulatory examination actually ask, and it is answerable only if history was retained with authority attached. The common failure is retaining text without context: the version exists, and whether it was approved, by whom, and under which policy regime is unrecoverable. Reconstructing that from email and memory is where audit response costs concentrate.
Centralpoint retains version, approval, identity and classification together on the record, so a historical position is extracted rather than reconstructed. Where an AI system answered questions during the period in question, the interaction record shows which version it drew on — which means the organization can establish not only what the document said but what staff were being told it said.
