Document Revision History

Revision history is the single most useful artefact in a document estate and the most commonly truncated. Systems retain recent versions and discard older ones for storage reasons, which is defensible until someone asks what the policy said four years ago, at which point the answer is unavailable. History is also where authority lives: knowing that a version existed is less important than knowing who approved it and under which rules.

Centralpoint retains version history as part of the record with approval and identity attached, so a question about a past state resolves to evidence. This is also what makes AI-assisted answers about historical positions possible: retrieval draws on the version that governed at the relevant time rather than on the current text, and the citation names which one.
