Both formats carry a vertical anchor on the box body — ODF
draw:textarea-vertical-align, DOCX wps:bodyPr/@anchor — and both
sides of the I/O hard-coded "top", so an imported box dropped its
centering and a saved one never got it. New textVAlign attr, read
and written in both formats, rendered by flexing the rotor (the
handles are absolute and stay out of that flow), set in the Shape
Format tab beside the vertical-text button.
The browser hit-tests a behind-text frame last of all — the page and every
paragraph over it come first — so a cover picture could not be clicked at all:
the caret landed in the text as if it were not there. A mousedown over one now
goes to the frame's own node view, which selects and drags it as any other
frame; text painted over the point still wins, as the caret does in both
products. A box's node view mirrors renderHTML's data-wrap for it, as an
image's already did.

Header and footer go first, each with its own ops, and a variant flag is
flipped while a zone is open. The round trip compares a list's drawn kind and
marker rather than its node type and style name — a list that loses its name to
a formatted marker carries the style's own char — and skips the marks of an
inline atom, which no file keeps. A caret is snapped to a text position, a
swallowed File-menu click is retried, and WebKit's converging ResizeObserver
round is no page error. A new corpus pair brings all six zones through the
import path; the baseline holds it and a re-recorded showcase entry.
tests/layout/baseline.json records where each page starts and what the load cost, per
engine and platform; a page starting elsewhere is a layout change the run prints page by
page, a load over three times its recorded time a regression, and LAYOUT_UPDATE=1 records
it again. The monkey draws frame sizes, wraps, alignment and column counts too, holds the
history against the edits rather than the caches the editor recomputes, and leaves it
unchecked where the columns flow rewrote the document outside it. The differences both
importers make by design are named in the comparison; unhoist moved to normalize.ts.
lo-fuzz.test.ts hands every fuzz seed to LibreOffice as .odt and .docx and
compares what comes back, listing the differences LibreOffice makes by design.
test:layout opens the corpus, the showcase and fuzz seeds in the browser, holds
the page count against LibreOffice and checks the lines for overlap, margin
escapes and stranded headings. test:monkey types at random on corpus documents
and asserts the schema, undo to the start, redo, and that both saved formats
read back. browser.mjs now carries the dev server and the settle helper.
The heading constants move to styles/headings.ts and the filename logic to
storage/documentName.ts, which were all the editor needed of the exporter
at startup. Main chunk 2.1 MB → 1.37 MB (gzip 615 KB → 411 KB).
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.
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.
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: 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.
