Worktree is a value (path->data dict). tree-from-files/tree-files round-trip
through real tree objects (cid-identical to hand-built trees); index =
{:base tree-cid :staged overlay} in kv with add!/rm!/unstage!/index-tree!;
status = three-way dict diff (HEAD vs index vs worktree) with
staged/unstaged/untracked. 26/26, total 132/132.

Objects are plain dicts over persist kv, addressed by sx1:<sha256> of the
artdag/canon canonical form (sorted dict keys) — native CIDs, extensible
fields participate in identity. 38/38.
