# Versioning

Every node edit goes through `nodes_history`: title, [markdown](page:4402) body, sort_key, parent are all snapshotted on each change. The data is preserved; what's missing is one-click revert tooling.

For now, recovery is manual: open the history, find the prior version, copy the text back into a `patch_node` or `update_node` call. Crude but reliable, and the audit trail itself stays useful for understanding why a section is the way it is.
