 | 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; omitted cell-margin edges inherit current table defaults; 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; an at-least row with less room than its minimum on a page that already holds something starts the next page whole (Allow row to break on or off, vAlign centre too), as observed in Word for Mac 2026-10-15 (a row of about 2.6 cm), #1742; that repeated header rows go with it and that a row taller than a page splits from the top of the next page come from the issue and synthetic tests, not a Word check (`…_an_at_least_row_with_no_room_starts_the_next_page_whole_either_way_breaking_is_set`, `…_an_at_least_row_taller_than_a_page_splits_from_the_top_of_the_next_page`, `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; a table with its own preferred width keeps it, however far past the margin, and only an automatic-width table over 1.5× the text width is squeezed to the margins (Word squeezes it as soon as it is wider) (#1721); 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; a click below one, outside its cells, goes to the text beside or after it, not to its last row, as checked in Word (#2038); exact line-bottom contact counts for tables only (#3977), both in row-span selection and word skipping; exact-spacing table contact uses the specified height rather than paragraph-mark metrics, with original Source Sans 3 controls in modes 11/12/14/15; expected Word rule from [cyril265's Word for Mac 16.114.1 measurements](https://github.com/storytold/wordcraft/issues/3977#issuecomment-6374217574), not a new Word run of these originals; anchor-order replay remains #3790's scope; other overlap rules untested | 2–3 |

 | Shape fills: gradients and transparency | 🟡 | #1500: linear (angle, `scaled`) and circular gradients and transparent fills drawn on screen, PNG and PDF (axial/radial shadings), soft edges fading the real fill; rectangular and shape-following path gradients drawn circular, `tileRect`/`flip` not drawn, outline gradients drawn in their middle colour, `rotWithShape="0"` drawn as turning with the shape | 2–4 |
 | 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) |

Paragraphs above an object's anchor wrap around it when it is placed higher up the page (the page is laid out again with it known from the start, #2048; when that wrap pushes the anchor onto the next page, the first page keeps the room and the object goes with its anchor, and a layout that still hasn't settled moves the object down to its paragraph rather than over text); text in an earlier column beside it doesn't yet, 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) | — |

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; a picture is decoded once for all its crops, and at most 2^28 pixels per layout are decoded (later pictures wrap as rectangles, #3692); not compared page-for-page with Word | 1–2 |

 | 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 |
 | Group connector rerouting | 🟡 | Glued ends keep their existing connection-site path; free ends, missing targets and invalid sites retain their displayed rotated and flipped position when the connector frame is rebuilt, including under nonuniform group scaling. Model and engine regressions cover all connector kinds, both ends, rotations/flips, unit/uniform/nonuniform scale, idempotent rerouting, degenerate dimensions without nonfinite writes, and fallback spans beyond the 4000 pt display-size cap without endpoint movement or repeated shrinkage. Non-invertible display scales and unrepresentable fallback spans leave connectors needing fallback endpoints unchanged; fully resolved connectors still reroute. Invalid child extents use the renderer's unit-scale fallback. Routing around obstacles remains missing; no new native Word comparison | — |
