Show HN: Version History for Your Synced Notes (AI Agent Safety)

EtherPK 0.22.0 adds automatic version history for every page and journal entry in a synced graph, creating versions as you write and before actions like delete, rename, merge, Replace all, or removing protection. Versions and deleted items are kept for a set period (30 days in the examples), thinned as they age, encrypted with the graph's key before upload, and restorable from a Version history tab or the Deleted documents and files section. AI agents connected to a synced graph can list and read versions via the list_versions and read_version tools but cannot restore them, which a person does in EtherPK.
