Delta

Delta compares the current snapshot to the previous snapshot for the same catalog root.

The tab appears when a prior snapshot exists in the DB.

What fills each pane

Pane	Content
Left	Change buckets — e.g. added, modified, removed
Middle	Paths in the selected bucket
Right	Overview for the selection; file rows can use right-pane tabs like Snapshot

Layout matches Snapshot so you can inspect what changed and open previews for modified files.

Typical workflow

1. Run a new snapshot after editing the tree.
2. Open Delta (~ or tab bar).
3. Select Added, Modified, or Removed on the left.
4. Walk the middle list; use Space quick actions where applicable.

Quick actions

File rows in the middle use the same Space menu as Snapshot (open, enhance, copy path, …). Lens add (l) applies to paths still in the catalog.
