<reusable-compact filename="spec.txt">
CommonMark 0.31.2 normative syntax and HTML examples. Leaf contracts include thematic breaks, ATX/setext headings, indented/fenced code, HTML blocks, paragraphs, blank lines, and link-reference definitions. Blocks precede inline parsing; code/HTML remain literal; first matching reference definition wins.
</reusable-compact>

<reusable-compact filename="spec_tests.py">
Runs supplied CommonMark examples against `--program`, optionally filtered by section regex. Verdict is process exit status: failures plus errors. Supports normalized HTML comparison and captures expected/actual diffs.
</reusable-compact>

<reusable-compact filename="normalize.py">
Normalizes HTML for conformance comparison by collapsing insignificant whitespace, normalizing block-tag spacing, canonicalizing attributes/self-closing tags, and resolving entities while preserving significant attributes and preformatted content.
</reusable-compact>

RESULT: FAILED

FILES CHANGED:
- commonmark

SUMMARY:
Implemented substantial leaf-block parsing improvements for fences, headings, thematic breaks, HTML blocks, paragraphs, indentation, and link references. Interface checks pass; scoped conformance improved from 122/187 to approximately 151/187, but failures remain.

BLOCKERS:
- Scoped leaf conformance is not yet green, especially nested/container interactions and several HTML/reference edge cases.

FAILURE_SUMMARY: Leaf-block conformance remains incomplete.
FAILURE_DETAIL: The executable runs successfully and interface checks pass, but the supplied scoped suite still reports failures; continue fixing block-container interactions, HTML block boundaries, and advanced reference definitions.
