What is Document Revision History?

Revision history is the 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 a policy said four years ago and the answer is unavailable. History is also where authority lives — knowing a version existed matters less 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 rather than recollection. That 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, so the organization can establish what its people were told as well as what it published.
