The 1x1 fixture carried an IDAT from a different image: its CRC fails and the
zlib stream is truncated. Chromium and WebKit render it anyway, Firefox reports
"Image corrupt or truncated", and the same bytes sat in eleven fixtures.
Three regression tests for what a 5000-seed sweep turned up, each checked to
fail without its fix. A run repeating its style's own plain underline is
lossy by design, so the generator no longer puts one under a named style.
tests/fuzzOptions.ts generates styles, outline numbering, sections with
zones, margins, paper and page numbering, decor, line numbering, notes and
metadata; the round trip compares per-section effective values, and what a
format has no place for is listed as lossy. The xmllint part of
schema-validation.test.ts moves to tests/schemaValidate.ts (one call per
schema) and a third leg validates every seed as ODT and DOCX. FUZZ_SEEDS
and SCHEMA_SEEDS widen the sweep.
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.
The generator assigns a builtin (node species following the style's
level kinds, override-, start- and marker-format-free — each of those
drops the name by design) and no longer pairs textAlign right with an
rtl paragraph, where it is the suppressed default. Found the w:jc
suppression fix the commit before this one.
An inline atom drawn gray as ‹label›: a click selects the whole field,
typing replaces it, Tab/Shift-Tab jump between fields. Exports to ODF
<text:placeholder> (PLH sentinel U+E022) and a DOCX w:sdt content
control tagged edentext-placeholder; both importers read it back, the
export-minted gray stripped. Covered in roundtrip Leg 31 + fuzzDoc.
styledTable now materializes the region attr (paintTable's shape), keeps
runs heading-safe only in bold regions, and layers direct overrides over
the paint: replaced or cleared cell shading and an own bottom border.
The generator now emits tableOfContents nodes of all five families, styled
tables painted through the real resolveTableCell (name + look + materialized
fill/borders), side-by-side topBottom image pairs (wrapAlign), vertical-text
boxes and the Caption paragraph style. normalize learns the index attr
defaults the DOCX TOC field has no switch for.
The generator now emits columns sections, Title/Subtitle/Quotations
paragraphs (heading-safe runs), floating text boxes with offsets, and
table margins, cell borders, cell padding and formula cells.
Generator gains insertion/deletion marks, sequence/index/date-time fields,
citations (one record per identifier), builtin character styles (redundant
direct marks dropped — import suppresses them like heading defaults) and
floating images (wrapDist only beside a side wrap). normalize canonicalizes
revision ids/dates like comments, recounts sequence numbers per category,
and drops an auto date field's value and a citation's derived label.
Generator: text boxes (shape, fill, stroke), inline and display
formulas, comments, bookmarks with cross-references, ruby, rowspan
merges. Display rides a formula owning its line; a stroke width needs
a stroke color; a vertical merge keeps a second column so no row is
all covered cells. Normalize canonicalizes comment ids and dates
(naive local vs UTC are one instant) and trims a formula's latex
(the OMML side keeps the serializer's trailing space on purpose).
New in the pool: paragraph shading/rule lines (also in cells and lists), rtl
paragraphs, keepNext/keepLines/widowControl, tab stops, custom bullet chars,
heading levels to 8, image alt/rotation, row heights and custom note labels.
noHyphenation stays out: without the document-wide hyphenate flag the
importers suppress it as meaningless. 1000 sweep seeds clean on both legs.
colspan merges (grid-consistent), orderedList listStyleType (upper-* only on
nested lists: lower/decimal forms are depth defaults the importers suppress),
and inline PNG images. 300 sweep seeds clean on both legs.
New in the pool: underline/strike line styles, super/subscript, caps,
textPosition, links, page breaks, footnotes/endnotes, cell shading and
vertical alignment. normalize() canonicalizes importer-generated note ids and
drops the link mark's default plain:false; FUZZ_SEEDS widens the sweep beyond
the default 50. This is the suite that surfaced the last four export/import
fixes; all 300 sweep seeds now round-trip clean on both legs.
tests/fuzzDoc.ts generates documents from a seeded PRNG (marks, lists,
tables, indents, XML-hostile text); fuzz-roundtrip.test.ts runs 50 seeds
through buildOdt -> importOdt and diffs the normalized JSON, naming the
failing seed. normalize/firstDiff moved out of roundtrip.test.ts into
tests/normalize.ts for reuse. The generator documents what is lossy by
design: default-equal marks in headings, indents and start in nested lists.
