Semantic HTML.
Compare what tools preserve.

Values must match exactly in the same row. An XML caption is not a column header; a Markdown table does not prove the input’s HTML semantics. Test scope.

The conclusion must be read with its unit, period, scope and caveat. Finding a word in an output is not enough to prove that the relationship was preserved.
