A STYLEREF field's result runs are the chapter a reader shows before it
repaginates. The DOCX import dropped them and set the field's text empty, so a
header saved as .docx came back with a blank running head. ODF kept it.
Found by comparing the header and footer zones on a round trip, which nothing
did — they are documents of their own and hold what only they can. The corpus
gains two legs besides: a second save, and Word's dialect on its way out as ODT.
The corpus legs pass seven of the exporters' nineteen arguments, so the other
twelve — note configuration, page decoration, line and page numbering, the
header/footer zones, document properties — were never round-tripped from a
file. A new unit test sets all of them and reads them back out of both formats.
The kitchen sink had only ever been written, never imported; it now makes both
round trips and comes back identical. Two fixture repairs it needed: notes in
anchor order, and a section break with sections to open.
Caught: a document holding no note yet lost its note configuration on .docx.
textBox becomes an inline node carrying block content, like the frame both
formats write, so "in line with text" really is in the line and a box reaches
a table cell or a list item through their paragraphs. Both exports write it
where it sits (an as-char draw:frame / a wp:inline drawing) and both imports
leave it there, which drops the hoisting machinery on either side.
Two guards the schema cannot express: no box inside a box, and a selection
reaching into a box grows to the box's bounds rather than dissolving it.
tests/kitchenSink.ts authors one deterministic document using every
feature; schema-validation.test.ts validates its .odt against the ODF 1.3
RelaxNG and its .docx parts (after MCE resolution, as Word reads them)
against the ECMA-376 transitional XSDs — the structural half of Word's
strict reader, which LibreOffice silently forgives. Schemas vendored under
tests/schemas/ (sources and offline patches in its README); self-skips
without xmllint, which CI now installs.
