Record eleven native subtree controls and a fresh-cache reopen, including empty-cell replacement, group normalization, indentation gaps and list-marker changes. Verify active identities, graph structure, preserved fields and independent native text/formatting; extend the shared controller to select paragraphs inside tables.

Validation: 143 Python tests pass; all eleven authoring inputs validate against the supplied XSD; both accepted Windows clones and the failed exploratory clone were removed.
