# Documentation changelog

> How documentation revisions are recorded\.

*Support \& policies → Resources*

Documentation is a governed surface\. Every publication is revision\-checked\, requires a written reason\, is authorised with MFA\, and is recorded in the audit trail with a before and after snapshot\.

- A stale editor cannot overwrite a newer revision\; the save is refused\.
- The public tree only ever exposes published spaces\, sections and pages\.
- Removing a page removes it from search\, navigation and the machine\-readable projections in the same commit\.
