Users can see who changed what and restore old states (ADR 0013). - shared: dependency-free word-level Markdown diff (diffMarkdown) with a unit test; PageVersionContentView; PAGE_RESTORE_CHANNEL + PageRestoreRequest. - api: GET /pages/:id/versions (list), GET .../:versionId (read-only HTML + Markdown for diffing), POST .../:versionId/restore. Every route requires write access — viewing history is gated like editing (permissions.md). Restore checks permission, then emits the page_restore NOTIFY; history is append-only (the api never deletes a version). - collab: a page_restore listener applies the restore on the live document via openDirectConnection — it snapshots the current state as a PRE_RESTORE version, then replaces the content in one transaction, so every connected client converges and the change persists like a normal edit. - web: HistoryPanel (version list with time/trigger/label/contributors, a read-only render of a selected version, a Markdown diff against the current page, and a restore action), toggled from the page menu. de+en strings. Tests: shared diff (added/removed/round-trip/edges); collab restore DB test (a connected client converges on the restored content; a pre-restore snapshot is appended alongside the original — append-only); api list/get/restore (newest-first, rendered content, write-permission gate, restore returns the target without mutating history). This completes M3 (real-time collaboration & history, #33–#42). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PGdhRiwU1WRL4XxJfZYipY
