+| Supported | Heading, paragraph, unordered/ordered list, quote, pullquote, code, preformatted, table, image, media-text, buttons/button, shortcode | Fixtures assert the block names and representative attrs currently emitted by `HtmlTransformer`. Media-text requires exactly two element children: one pure image/video side and one text-bearing side; ambiguous layouts retain existing columns/group behavior. |
 | Unsupported fallback | Unknown/custom elements, SVG markup, form controls, other unsupported top-level HTML | Fallbacks use `type: unsupported_element`, include the source tag, selector, caller source/scope when provided, sanitized HTML, and increment `coverage.0.fallback_count`. |
 | Context-required | Interactive/form behavior, embeds, advanced layout semantics, raw-handler hooks | These require WordPress/Gutenberg runtime context or richer product converter behavior and remain outside the PHP transformer's supported slice. |
 | Gutenberg editor validation | Gap | The repository has no browser harness that boots Gutenberg, registers generated companion blocks, and validates load/edit/save output. `wp_block_validity` is a PHP structural and canonical save-shape check; the WordPress integration test and Playwright visual-parity tooling do not exercise the editor. |
