Remove Time Travel's floating modal behavior so it uses the standard centered modal shell and shared backdrop like Settings. Keep the modal-only sizing classes on the component document and stop exempting Time Travel from backdrop rendering.
Force-add curated snapshot paths so workspace .gitignore rules cannot break Time Travel snapshots, while preserving Time Travel's own exclusions for secrets and generated files.
Repair invalid shadow Git repositories by restoring HEAD when possible or quarantining and reinitializing unusable repos, and canonicalize workspace paths to avoid duplicate shadow histories for aliases.
Add regression coverage for ignored paths, corrupt shadow HEAD recovery, and canonical workspace identity.
Add a Time Travel entry directly under Files in the sidebar dropdown and route it through the existing modal. Stop Time Travel from registering or mounting a right-canvas surface, and keep modal refresh tied to the modal state.
Register Time Travel on Agent Zero's existing /a0/usr watchdog and coalesce automatic snapshot triggers into a single pending commit window capped at one commit per workspace every 10 seconds.
Exclude top-level /a0/usr plugins and nested Git worktrees from root snapshots, preserve self-root Git workspace tracking, and cover the behavior with Time Travel tests.
Add the _time_travel core plugin with Agent Zero-owned shadow Git snapshots, history/diff/preview/travel/revert APIs, capture hooks, and canvas plus floating window UI surfaces for /a0/usr workspaces.
Wire generic file-browser mutation hooks for UI edits, update modal backdrop handling, remove the legacy _diff_viewer plugin, and replace Diff Viewer tests with focused Time Travel coverage.
