 Feature coverage (element/style checkboxes) is tracked in [`README.md`](README.md).
-The drawing gap — transforms, the unparsed shape elements, enhanced geometry and
-the embedded chart — has its own staged plan in [`PLAN.md`](PLAN.md) (#771).
+The drawing gap #771 named — transforms, the unparsed shape elements, enhanced
+geometry and the embedded chart — is closed; what is left of drawings is the
+unticked boxes in [`README.md`](README.md). Two of them are deliberate rather

+since re-routing one between the shapes it names is layout rather than
+decoding.
