A document only "opens correctly" if its pages break where Word breaks them: the same lines, the same page count, footnotes and pictures on the same pages. This checklist covers line breaking, pagination and object placement in crates/layout. Typing behaviour is in typing-parity.md; the reading and writing of the properties is in file-format-parity.md.

Dimension: ~55% (estimated), 90–145 h to full (the sum of the rows below). The engine implements most of Word's layout rules, but nothing has been compared page-for-page with Word on real documents, and the default font can't match Word's metrics.

Checklist

✅ matches Word as far as our tests show · 🟡 implemented, differs or untested against Word · ❌ missing

Feature	State	Evidence / gap	Hours
Line breaking (UAX #14 with Word's exceptions: no break after /)	✅	layout::tests::no_line_break_right_after_a_slash	—
Justification, Word 2013+ space shrinking (compat mode 15)	✅	#109	—
Complex scripts (Myanmar, Khmer, Indic): shaped per script run with OpenType fallback fonts, one cluster per syllable, Myanmar wraps between syllables	🟡	layout::tests_complex (#604). Khmer, Thai and Lao still wrap only at spaces (need a dictionary)	4–8
Kashida justification (Arabic)	❌	no kashida in crates/layout	3–5
Distributed / Thai distributed alignment	🟡	read; layout untested	1–2
Default font metrics (Aptos, Calibri, Cambria…)	🟡	Carlito/Caladea/Liberation are metric-compatible for Calibri/Cambria/Arial/Times/Courier; Aptos (Word's default since 2024) has no metric-compatible open substitute, so new Word documents wrap differently (typing-parity.md Known gaps). Needs an owner decision (commission or license a metric-matched font)	6–10 + owner
Colour emoji and colour fonts on screen and in page renders: COLR v0/v1 paint graphs (solid fills, linear, radial and sweep gradients, composite modes) and bitmap strikes (Apple Color Emoji sbix, Noto Color Emoji CBDT) drawn in the font's colours at the layout's position and size; a dark page doesn't invert them, the same as pictures	🟡	fonts::color (skrifa), render::color_glyph; render::tests_color_glyphs::emoji_are_drawn_in_colour and emoji_keep_their_colours_on_a_dark_page (system font, skip without one), render::color_glyph::tests, fonts::color::tests (#1269). CBDT is verified on a real page with Noto Color Emoji; COLR v0/v1 and sbix are implemented to the OpenType spec and tested with synthetic data, but not yet seen on a real font (Segoe UI Emoji, COLRv1 Noto, Apple Color Emoji). PDF export already drew them through krilla	1–2
Symbol fonts (Symbol, Wingdings, Wingdings 2/3, Webdings) without the proprietary font: each character, stored as U+F020–U+F0FF or a plain 8-bit code, is drawn as its Unicode equivalent from a face that has it; PDF text and copies read as those symbols	✅	doc::symbol_fonts tables (Adobe Symbol table and Unicode L2/12-368), layout::tests::wingdings_text_draws_and_reads_as_its_unicode_symbols (#776). Shapes come from Noto Sans Symbols / Symbols 2, DejaVu Sans or Segoe UI Symbol, so they differ from Word's; Wingdings 0xFF (not in Unicode) still has no symbol	—
Indents in characters (w:firstLineChars, w:leftChars…), measured in the paragraph mark's font size	✅	#534, layout::tests::character_indents_use_the_paragraph_mark_size; spacing in lines (w:beforeLines/w:afterLines) uses the stored points (needs the document grid)	—
Line spacing (single, 1.5, double, at least, exactly, multiple), spacing before/after, contextual spacing	🟡	Contextual spacing measured in body paragraphs and headers (below), with a four-paragraph table-cell regression; list-label ascent overflow is unscaled by multiple spacing and uses descent for automatic and at-least spacing (#601); other line-spacing combinations remain (#108, #135 open)	3–5
Kerning only where Kerning for fonts asks for it (w:kern, at or above its size)	✅	Measured in Word for Windows: no w:kern or w:kern="0" is unkerned; WordCraft kerned every run, so its lines held more text than Word's. layout::tests::kerning_follows_kerning_for_fonts_like_word	—
Automatic (HTML-style) paragraph spacing (w:beforeAutospacing, w:afterAutospacing)	✅	Measured in Word for Windows: 14 pt at any size, none at the top of the document or a cell or after a cell's last paragraph, the larger of two neighbouring spaces. layout::tests::automatic_paragraph_spacing_like_word, …_drops_at_cell_edges	—
Paragraph boundaries inside field instructions	✅	Synthetic DOCX observed in Word: instruction-only paragraphs add no height; the empty result keeps a line. docx::fixtures::field_code_spans_paragraphs, layout::tests::hidden_marks_take_no_space. Other field-code display modes remain unverified	—
Widow/orphan control, keep with next, keep lines together, page break before	✅	lib.rs keep_next/keep_lines; a line holding only a page break stays at the bottom of a full page instead of leaving a blank page (#534); a paragraph ending with a page break keeps its space after on the old page, so the next page starts at the top (compatibility modes 12 to 15, layout::tests::space_before_at_the_top_of_a_page_like_word); a three-line paragraph with room for two moves whole (neither a widow nor an orphan is allowed), as in Word	—
Tabs (left, center, right, decimal, bar), leaders	🟡	Bar tabs untested	1–2
Hyphenation (automatic, zone from the document, words in capitals, soft hyphens, consecutive limit, Manual Hyphenation, #407)	🟡	English patterns only; other languages hyphenate wrongly or not at all	in localization
Drop caps	✅	2026-10-06	—
All Caps and Small Caps: the full capital of each letter, so ß draws as SS (ff as FF); the capitals drawn for one character are one cluster, so the caret, selection, hit testing and line breaking treat ß as one character	✅	layout::tests::caps_draw_sharp_s_as_two_capitals_in_one_cluster (#1581). The PDF text layer still reads the document's lowercase letters until #1473	—
Columns, column breaks, separators, balancing	✅	Columns balance on a section's last page when the next section starts continuous (also at the document end, which Word only balances when the document ends with a continuous break); not after next-page/even/odd breaks or on a page with a column break; keep-together, keep-with-next, widow/orphan control and unsplittable rows can leave them slightly uneven (#350)	—
Section breaks (next page, continuous, even, odd), different first page, odd/even headers	✅	Section breaks don't show in Draft view (#42). A break inserted with text selected goes before the selection and keeps it, as in Word (#852)	1–2
Labels on page-break-only list paragraphs	✅	layout::tests::break_only_list_has_no_label: no bullet or number on the break, but the next number is still 3 after item 1 and a break. Plain empty items keep their labels. Synthetic DOCX observed through Adobe PDF conversion	—
List labels: number formats (decimal, letters, Russian letters, roman, ordinal text, Chinese/Japanese/Korean counting and legal, 一〇一 digits, 甲乙丙, ①…⑳, full-width), %n text such as 第%1章 / （%1）, legal numbering	✅	doc::cjk_numbers tests, doc::section::tests::russian_letters_follow_word, layout::tests::chinese_counting_list_labels_and_their_font_runs, layout::tests::russian_letter_list_labels_draw_cyrillic; a label mixing faces (digit + CJK comma) is drawn run by run (#534); Russian letters skip ё, й, ъ and ь and then double (аа, бб), as observed in Word. Hebrew, Arabic, Hindi, Thai and Vietnamese formats show decimal The label stays attached to the start of the text when the paragraph is centred or aligned to the end, as in Word (#1159).	—
Body top below a tall header, footer pushes body up	✅	#138; a footer taller than the bottom margin moves the body bottom up (#453), and a header or footer linked to the previous section takes its room too (#454)	—
Footnotes at the page bottom, endnotes at the end, note numbering	🟡	A long note continues onto the next page at a line boundary (its first line stays with the reference), first in that page's note area under a full-width continuation separator (#352); the document's own separator, continuation separator and continuation notice are drawn (the notice under a note that continues); on a page with footnotes a paragraph ending there keeps its space after above the separator, or its last lines go to the next page with the note (#1116); a long endnote continues on the next column or page at a line boundary (#456), and the caret finds note text on its continuation page (#457); each section's note options: footnotes below the text, endnotes at the end of each section, start at, numbering restarted each section or each page (counted from where the notes land, at most three passes) (#385)	1–2
Tables: row heights (at least/exact), rows split across pages, header rows repeat, Can't Split	✅	2026-10-06, #138; every cell in a row gets the row's largest top and bottom margin; an exact height covers the top border, top margin and text, the bottom margin comes on top, and an exact row never splits; a row split across pages keeps its cells' bottom margin, border and last space after on the first page, widow/orphan control applies in its cells, each cell continues at the top of the next page and an at-least row keeps its minimum (layout::tests::a_row_shares_its_largest_top_and_bottom_margins, …_a_split_row_keeps_its_bottom_margin_and_widow_control, …_split_row_cells_each_continue_at_the_top)	—
Tables: autofit to contents/window, fixed widths, Word 2013 edge	🟡	#137; #44: AutoFit Contents measures each column's narrowest and widest text and shares the width like Word, once (not live as you type); consistent a percentage width past 100% is kept, as Word does; cell widths override stale grid proportions when their totals agree (cell_widths_override_grid); conflicting widths and spans still differ	3–5
Floating tables (w:tblpPr)	🟡	#137; one placed on the page or margin that would cover visible text before it and does not fit below it moves to the next page (#534); empty line-break lines do not count as text; other overlap rules untested	2–3
Nested tables	🟡	render; polish missing	2–4
Floating pictures/shapes placement (relative to page/margin/column/paragraph/line/character)	✅	#136	—
Text wrap: square, top-and-bottom, behind, in front	✅	2026-10-06; beside an object, a line's first word that doesn't fit the strip goes on whole to the row's next strip or the next row, instead of being split (#1376, layout::tests::a_word_too_wide_for_the_strip_beside_a_float_moves_on_whole; inferred from a reporter's comparison, not yet measured in Word) a paragraph running on into the next column or page is broken again there around that column's shapes, its own floating objects left where they are (#1374). Text in an earlier column doesn't yet wrap around a shape anchored in a later one (#1158)	#884: an object dragged on a multi-column page anchors to a paragraph in the column it lands in, so that column's text wraps around it. Text laid out before the anchor (an earlier column) doesn't yet wrap around an object anchored later on the page, nor do lines a paragraph continues into the next column (broken once, in the column it starts in)
Text wrap: tight, through (contour, wrap polygon)	🟡	#354: lines follow the wrap polygon, or the outline worked out from the object (shape geometry; a picture's opaque pixels as a convex hull; otherwise the rectangle), turned and flipped with it, kept the left/right distance from text; Through also uses gaps inside the outline. Wrap side (wrapText: both sides, left only, right only, largest side per line) applies to square, tight and through wraps, turned objects included; picture outlines are convex; not compared page-for-page with Word	1–2
Text boxes, overflow, linked text boxes	✅	#46; linked text boxes (#369): the text runs on through each box in turn at that box's line length, overflow past the last box hidden; Align Text top / middle / bottom; the box's own internal margins, and a box set to Resize shape to fit text shows all its text (#743)	—
Rotated objects and text	🟡	#332: pictures, shapes, charts and groups drawn turned and flipped about their centre (screen and PDF); square wrap and inline lines keep clear of the rotated bounds; hit testing on the turned shape. Text in a rotated text box stays upright	2–3
Page borders (from page edge or text), page colour, watermark	✅		—
Line numbers (restart per page/section, count by)	✅		—
Vertical page alignment	✅	Top, Center, Bottom and Justified (#1320): justified shares each page's spare room equally between its paragraphs and tables, first line on the top margin and last on the bottom one (above the footnotes), the last page and a page ending in a manual page break too; a page with one block stays at the top; the last paragraph's space after stays inside the justified height (Word for Mac, user-checked). A section's last page takes its own section's alignment (it took the next section's before). Multi-column justified pages stay at the top (not compared with Word)	—
Gutter, mirror margins, book fold, 2 pages per sheet	🟡	gutter and mirror margins (even pages put the inside margin and gutter on the right, #452; page-relative floats stay put, and inside/outside alignment and margins follow the page side, #1181); book fold missing	2–3
Vertical text (tbRl) in sections and text boxes; cell text direction	✅	cell text direction (#245); text-box text direction (#369); vertical sections (tbRl/btLr, #491): the page's text area turned, lines top to bottom stacking right to left, ideographs, kana and Hangul upright, Latin on its side, caret and clicks through the turn. Missing: OpenType vert alternates (punctuation is moved, not substituted), arrow keys along vertical lines, upright pictures take turned room	2–4
Document grid (w:docGrid, lines per page, characters per line)	🟡	#391, #401: line grid snaps line heights to whole pitches (text centred in them; w:snapToGrid off opts a paragraph out); character grid puts East Asian characters on the character pitch (linesAndChars) or all text (snapToChars), Latin text proportional; View › Gridlines draws it. Not yet: run-level w:snapToGrid, grid in headers/footers, paragraph spacing in grid lines, Word's exact glyph placement in a cell	1–2
Ruby / phonetic guide, enclose characters, combined characters	🟡	ruby (Phonetic Guide) landed (#288): ruby text over its base by alignment, line grows to fit, in PDF; enclose and combined characters missing; ruby not yet compared with Word page by page	2–4
Bidirectional paragraphs, mixed-direction lines; RTL tables and sections	🟡	#207; RTL tables (#362): grid columns from the right edge, start alignment and indent from the right margin, cell margins and left/right borders mirrored, merged and turned cells and nested tables included; RTL sections (#362): newspaper columns right to left with the line between mirrored. Right-hand page gutter (w:rtlGutter) missing	1
Equations: display layout, numbering, wrapping long display equations	✅	#191; long display equations break at top-level operators (m:brkBin, m:brkBinSub), manual breaks and m:alnAt, continuation lines indented by m:wrapIndent or set right (m:wrapRight) (#326)	—
Hidden text excluded from breaking and hyphenation	✅	#173	—
Fields: PAGE, NUMPAGES, SECTIONPAGES, TOC page numbers	✅	#52; totals in the body need a second pass once the page count is known (#451)	—
Compatibility modes (Word 2003/2007/2010 layout for old files: w:compat options)	🟡	allowSpaceOfSameStyleInTable supported in modes 11/12/14; mode 15 retains contextual suppression. Most other legacy compat options remain ignored	10–20
Fields: STYLEREF in headers and footers (running chapter titles)	✅	Evaluated per page at layout time: the page's first (or with \l last) paragraph of the style, else the nearest before it; style name, id or heading level (a level finds the style named heading N whatever its id, so localized documents match, #1286); character styles; \n \r \w \s \t \p (\r treated as \w); body STYLEREF updated with the other fields (#775). Header paragraphs are cached on their per-page results, so typing in body text no STYLEREF shows doesn't lay the headers out again (#1286)	—
Fields: PAGE, NUMPAGES, SECTIONPAGES, TOC page numbers, PAGEREF in headers and footers	✅	#52; totals in the body need a second pass once the page count is known (#451); a PAGE field in a paragraph that runs onto a later page (a page break inside it, or a natural split) shows that page's number, the rest of the paragraph broken again for the wider result (#1352); PAGEREF in headers and footers shows its bookmark's page, filled in after pagination like their totals (#1477); in the body it keeps its result until fields are updated	—
Page-by-page comparison harness against Word	❌	Run Word locally on our own synthetic documents, export PDF, compare line breaks; Word output stays under plan/ (never committed)	8–12

List-label line spacing

Controlled original DOCX probes against Word for Mac 16.113.3 (26092714), macOS 26.6.2, compatibility mode 15, zero paragraph gaps, Roboto Regular 12 pt body text: a label's positive ascent overflow adds to the text line pitch without being multiplied by automatic spacing. Label descent does not enlarge automatic or AtLeast spacing. A label's ascent includes positive hhea leading. The original base split text leading across ascent/descent; current main assigns its full gap to ascent too, so labels now use that shared metric. The table records the original measurements, not a new native comparison of this rebase. These are observations of synthetic documents, not a claim about Word's internal implementation.

Label / spacing	Word baseline gap	Fixed WordCraft	Before fix
Roboto 24 pt / single	25.20 pt	25.1953 pt	28.125 pt
Roboto 24 pt / 1.25	28.80 pt	28.7109 pt	35.1563 pt
Roboto 24 pt / double	39.36 pt	39.2578 pt	56.25 pt
Apple Symbols 12 pt / AtLeast 12 pt	13.92 pt	14.0625 pt	14.6338 pt
Apple Symbols 24 pt / AtLeast 12 pt	20.88 pt	20.9297 pt	24.0 pt

Actual font metrics and original-input provenance were checked locally; Word-derived exports remain uncommitted. Tolerance is 0.25 pt; this evidence covers Latin text with the tested symbol and decimal labels, automatic single/1.25/double spacing, AtLeast controls, Exactly 24 pt, wrapped paragraphs and save/reopen. Regression tests inject the independently measured metrics so CI does not require those installed fonts. Inline pictures retain their existing height floor. Picture bullets are not implemented, and the private Linux Symbol substitution report has not been reproduced. Absolute baseline-leading placement remains the separate #108 contribution. This narrows gap #4 without raising the overall readiness estimate.

Legacy table contextual spacing

Observed in Word for Mac 16.113.3 (build 26092714) on macOS 26.6.2, using original synthetic DOCX files, Roboto Regular 12 pt, exactly 24 pt lines, equal paragraph styles, both paragraphs contextual, first paragraph after-space 12 pt and before-space 0 pt. The one-cell table had no borders or cell margins. Baseline separation was 36 pt with w:allowSpaceOfSameStyleInTable enabled in compatibility modes 11, 12 and 14, versus 24 pt with it disabled. Mode 15 measured 24 pt in either state. Body and header controls in modes 14 and 15 measured 24 pt with the flag enabled. Comparison tolerance: 0.25 pt.

The model and DOCX reader/writer preserve the flag. Cell layout bypasses contextual suppression only for enabled modes 11/12/14, including cells without table-style formatting. Tests: legacy_table_contextual_spacing_flag_keeps_after_space and legacy_table_contextual_spacing_flag_is_scoped_to_cells_and_legacy_mode. WordCraft original-open and save/reopen measurements match all 12 controls; reopening its saved DOCX files in Word retains the same gaps. Word-derived exports stay local under ignored plan/word/; no Word-generated fixture is committed.

The published option specifies an override inside tables. Its mode 15 exception is not explained by that source; the guard follows this observation. MS-DOCX compatibilityMode allows 11, 12, 14 and 15. Mode 13 is invalid and Word rejected its synthetic input. Ordinary overlapping before/after space and one-sided contextual spacing remain separate work in #108 and #568. Nested tables, rotated cells, other fonts and Word for Windows were not reference-tested here. This closes one compatibility-option gap, not table parity.

Contextual paragraph spacing

Observed, 2026-10-11: original synthetic DOCX probes in Word for Mac 16.113.3 (build 26092714), compatibility mode 15, Roboto Regular 12 pt, Exactly 24 pt line spacing. With identical paragraph style IDs and contextual spacing enabled only on the first paragraph, 12 pt after / 8 pt before adds 0 pt to baseline separation; 10 pt after / 12 pt before adds 1.92 pt, within the predeclared 0.25 pt tolerance of 2 pt. Body paragraphs and headers give the same results. Enabling only the second paragraph preserves the first paragraph's 12 pt after-space.

The first-only residual agrees with the worked example in ISO/IEC 29500-1 §17.3.1.9. contextual_after_removes_a_smaller_before_gap, contextual_after_keeps_only_the_residual_before_gap, and contextual_spacing_preserves_each_side_and_style_identity pin those relative gaps and controls in body and header layout. Different style IDs retain their spacing even when their definitions are identical.

This fixes contextual suppression in place_para and layout_box. Ordinary before/after overlap still needs #108; the uniform first-baseline offset, page boundaries, tables, text boxes and notes were not compared with Word in this study. No overall parity estimate changes from these probes.

Revision history

Date	Change	Summary
2026-10-14	trivial	Consistent cell widths override a stale table grid
2026-10-14	trivial	Paragraphs inside complex-field instructions take no flow height; empty result paragraphs keep their line.
2026-10-14	trivial	A list paragraph containing only a page break has no visible label; it still advances the list counter. Ordinary empty list items keep their label.
2026-10-14	trivial	With w:doNotUseHTMLParagraphAutoSpacing the space between two paragraphs is the first's space after plus the second's space before, as measured in Word; without it, still the larger (#733)
2026-10-14	trivial	An inherited header or footer sizes its percentage-width tables by the section that defines it, as measured in Word (a portrait footer table keeps its width on inheriting landscape pages)
2026-10-14	trivial	An empty paragraph closing a section before a new page stays on a full page instead of starting a page of its own, as measured in Word
2026-10-14	trivial	A table row with an at-least height doesn't split where less than that height is left on the page; it starts the next page whole, as measured in Word
2026-10-14	trivial	Text that doesn't fit an exact-height table row is cut off at the cell's edge, as in Word, instead of drawn over the rows below
2026-10-14	trivial	A numbered paragraph whose text opens with a page break draws its number on the next page with the text, as Word does
2026-10-14	trivial	A bookmark (or other zero-width marker) after a paragraph's closing page break stays with the break instead of taking a line at the top of the next page
2026-10-14	trivial	A paragraph of only a page break followed by a page break before, or carrying a next-page section break, starts one page, not two: the break's mark and its space after stay on the page before, as in Word
2026-10-13	trivial	Justified vertical page alignment (#1320): the page's spare room goes equally between its blocks; a section's last page takes its own section's vertical alignment, not the next one's
2026-10-13	trivial	Floats and floating tables aligned inside/outside, or placed in the inside/outside margin, swap sides on even pages; with mirrored margins, page-relative floats keep their place and left/right margin areas are each page's own (#1181)
2026-10-14	trivial	Widow control: a three-line paragraph with room for two of its lines at the bottom of a page moves whole, as in Word (no two-and-one split leaving a widow); a paragraph continued from the previous page may still take one line along from two
2026-10-13	trivial	PAGEREF in headers and footers shows its bookmark's page (#1477)
2026-10-14	trivial	All Caps and Small Caps draw ß as SS, as Word does, kept one character for the caret and selection (#1581)
2026-10-14	trivial	A word too wide for the strip beside a square-wrapped object moves past it whole instead of being split across the strip (#1376)
2026-10-14	trivial	Russian letter list formats (russianLower, russianUpper) draw а) б) в) … аа) бб) as Word does, instead of digits
2026-10-14	trivial	A table's percentage width past 100% is kept, so a table pulled into the margins spans them as in Word
2026-10-14	trivial	A section can restart its page numbers at 0 (w:pgNumType w:start="0"), as a cover page numbered 0 does; the restart was read but laid out from 1
2026-10-13	trivial	A shape or picture dragged into another column anchors there, so the text in that column wraps around it (#884)
2026-10-13	trivial	On a page with footnotes, a paragraph that ends there keeps its space after above the footnote separator; if it doesn't fit, its last line (and, with widow control, one more) goes to the next page with the note. Pages without notes are unchanged (#1116)
2026-10-12	trivial	STYLEREF fields in headers and footers show each page's chapter (or other styled text); Insert › Quick Parts › Field offers STYLEREF (#775)
2026-10-12	trivial	a list label moves with its first line when the paragraph is centred or end-aligned (#1159)
2026-10-13	trivial	A paragraph ending with a page break keeps its space after on the old page with its mark: the next page starts with the next paragraph at the top (it started that much too low, and a page break before after it opened a blank page)
2026-10-13	trivial	Table rows: every cell gets the row's largest top and bottom margin; exact rows add the bottom margin on top and never split; a split row keeps its cells' bottom margin, border and space after on the first page, applies widow control in its cells and continues each cell at the top of the next page
2026-10-14	trivial	A paragraph continued into the next column or page is broken again around the shapes there, not the ones where it started (#1374)
2026-10-13	trivial	PAGE fields after a page break inside their paragraph, or on a page the paragraph runs onto, show that page's number (#1352)
2026-10-14	trivial	Colour emoji row set to 🟡: CBDT verified on Noto Color Emoji; COLR v0/v1 and sbix not yet seen on a real font (#1269)
2026-10-14	trivial	Colour emoji and colour-font glyphs (COLR, sbix, CBDT) drawn on screen and in page renders (#1269)
2026-10-12	trivial	Document grid: the stale ❌ row removed; the 🟡 row (#391, #401) is the only one
2026-10-12	trivial	Spaces, tabs and ideographic spaces don't count toward a line's height, as in Word (a line of only them takes the paragraph mark's)
2026-10-12	trivial	A list label's font raises the first line's ascent but never its descent (Word keeps the text's descent below the baseline)
2026-10-12	trivial	Hidden end-of-cell mark (w:hideMark): a cell's empty last paragraph takes no room, spacing and all; a row of only such empty cells is just its borders
2026-10-12	trivial	Text frames in headers, footers, cells and text boxes are placed like floating objects with the text wrapping around them; body frames still lay out in line
2026-10-12	trivial	List indents and style indents combine like Word's: a numbered style's own indents (and those of styles based on it) beat the list level's, its base styles' don't, the paragraph's own list beats every style; a paragraph that switches its list off (numId 0) drops the styles' indents
2026-10-12	trivial	Keep with next: a paragraph that doesn't fit on the page anyway breaks as usual (its last lines go over with the next paragraph) instead of moving whole; a chain of kept paragraphs moves together
2026-10-12	trivial	Continuous section breaks: an empty paragraph carrying only the break takes no room (text after it follows on; balanced columns ignore it)
2026-10-12	trivial	Floats relative to a paragraph (or its line) are measured from the paragraph's start above its space before
2026-10-12	trivial	Text after a column break in unequal columns is broken for its new column's width
2026-10-12	trivial	Space before at the top of a page after page breaks, measured in Word for Windows in compatibility modes 12 and 15 (32 cases)
2026-10-12	trivial	No automatic (HTML-style) spacing between two list items, of one list or two, at any level; the first item keeps its automatic space before and the last its space after
2026-10-12	trivial	Kerning only where the document asks for it, and automatic (HTML-style) paragraph spacing, both measured in Word for Windows against real .gov documents
2026-10-12	trivial	A section break inserted over a selection keeps the selected text: the first section no longer comes out empty (#852)
2026-10-12	trivial	Large-table scrolling (#811): per-frame page fingerprinting fixed; measurement added
2026-10-12	trivial	Symbol-font text (Wingdings, Wingdings 2/3, Webdings, Symbol) drawn as Unicode symbols (#776)
2026-10-14	trivial	Floating-table overlap checks use visible line content; empty line-break lines no longer move a table
2026-10-11	trivial	Chinese documents (#534): indents in characters, a page-anchored floating table after a full page moves to the next page, no blank page from a page break at the bottom of a full page
2026-10-11	trivial	East Asian list number formats (一、二、三, 第一章, ①); list labels whose characters come from two fonts draw each part with its own font (the digits of "1、" no longer show as other letters); a list level without indents leaves the label at the paragraph edge (#534)
2026-10-11	trivial	Vertical sections: w:textDirection in w:sectPr, upright East Asian glyphs (#491)
2026-10-11	trivial	Mirror indents (w:mirrorIndents): left/right indents swap on even pages; suppress line numbers inherited from styles (#512)
2026-10-11	trivial	NUMPAGES/SECTIONPAGES in the body show the real totals (the body is laid out again once the page count is known, at most three extra passes, #451); footnotes referenced in table cells go to the page bottom (#450); PDF links to a bookmark go to the page its start is on, not its paragraph's first page (#455)
2026-10-11	minor	Complex scripts: script itemisation, OpenType fallback fonts, syllable clusters, Myanmar syllable breaks (#604)
2026-10-11	trivial	Mirrored margins on even pages, tall and linked footers/headers push the body, long endnotes continue, caret in continued notes (#452, #453, #454, #456, #457)
2026-10-11	trivial	Hyphenation zone, words in capitals and consecutive-hyphen limit follow the document settings; Manual Hyphenation (#407)
2026-10-11	trivial	Document grid: line and character pitch (#391)
2026-10-12	trivial	Text boxes use their own internal margins; Resize shape to fit text never cuts text (#743)
2026-10-11	trivial	Linked text boxes, Align Text and text-box text direction (#369)
2026-10-11	trivial	Right-to-left tables and sections laid out mirrored (#362)
2026-10-10	trivial	The document's own note separators and continuation notice are drawn (#352)
2026-10-11	trivial	Newspaper columns balance before a continuous section break (#350)
2026-10-12	minor	Measured synthetic list-label line height; automatic and AtLeast spacing keep text descent and unscaled label ascent overflow
2026-10-12	trivial	Legacy table contextual spacing measured and supported; modes 11/12/14 versus 15 checked with original synthetic documents
2026-10-11	minor	Body/header contextual spacing corrected from original Word probes; ordinary overlap remains #108
2026-10-11	trivial	Group and Ungroup keep turned members' orientation and placement (#441, #443); Size resizes a group (#442); the eraser hits turned ink where it is drawn (#445)
2026-10-10	trivial	Long footnotes continue onto the next page with a continuation separator (#352)
2026-10-11	trivial	EQ \o fields overstrike their arguments; enclosed characters draw their circle, square, triangle or diamond as vectors (#297)
2026-10-11	trivial	Ruby (Phonetic Guide) layout landed (#288)
2026-10-10	trivial	Wrap side: text on both sides, left only, right only or the largest side of an object (#354)
2026-10-10	trivial	Tight and Through wrapping follow the object's outline (#354)
2026-10-10	trivial	Rotated and flipped objects laid out and drawn (#332)
2026-10-11	trivial	Footnotes below text, endnotes at the end of each section, note numbering restarted per section or page (#385)
2026-10-10	trivial	Long display equations wrap across lines (#326)
2026-10-10	trivial	AutoFit Contents measures the text (#44)
2026-10-10	major	First version: layout and pagination checklist with evidence from crates/layout, PRs and issues

Maintenance on 2026-10-12 retains current tracked-deletion, endnote, footer-total, text-box and balloon layout while supplying explicit cell identity at every box call. The native Word probes above are historical; this rebase has no new native or other-platform measurement.

Repeated table-cell control, 12 October 2026: four same-style contextual paragraphs with 6 pt before/after and exactly 24 pt lines retain zero extra gap at every boundary. The body control uses the same fixture. This is an original specification-based regression; no new native Word table comparison was run.
