 ## Tasks
 
-- [ ] Track walk sessions, observability (parameters used, etc.)
-- [ ] Add args/option for running ./cactl.ts with a starting root path
+- [ ] Add SQL in notebook to easily remove and vacuum all sessions, walk paths,
+      and walk entries prior to a given date.
+  - [ ] Add SQL in notebook to easily remove all sessions, walk paths, and walk
+        entries except the ones referenced by the most recent session.
+- [ ] Add SQL in notebook to report on the differences between sessions (files
+      added, modified, removed)
+- [ ] Add args/option for running ./cactl.ts with a starting root path(s)
 - [ ] Figure out what to do about symlinks
 - [ ] Figure out what to do when fileio_read cannot read larger than 1,000,000
       bytes for hash, etc.
