 | 2026-11-02 | trivial | ODT: a chart lost the look WordCraft doesn't model (its fonts and sizes, axis and grid lines) on save, written anew from WordCraft's chart. The chart object as read is kept (through drawing it again when it opens or is resized), and written back whole while the chart reads the same; an edited chart is written from WordCraft's chart as before. The chart documents round-trip pixel-identical (`charts::an_unchanged_chart_is_written_back_as_it_was_and_an_edited_one_anew`, `engine::tests::redrawing_a_chart_keeps_the_chart_as_read`). Found with LibreOffice's serif business letter: a text frame outlined by its drawn stroke (`draw:stroke`, no `fo:border`) lost its outline; it's the frame's line. A header or footer whose style states no height (or that has none) was 0 tall; it's LibreOffice's 0.5 cm (measured), so the text no longer moves up. The letter round-trips to 116 differing pixels (from 4,223) (`text_boxes::a_frames_drawn_stroke_is_its_line_when_it_has_no_border`, `headers::a_header_without_a_stated_height_is_half_a_centimetre`) |
 | 2026-11-02 | trivial | ODT, found with LibreOffice's agendas: saving wrote every table's first row as a header row (`table:table-header-rows`), repeated at the top of each page, because a table style's header row (on by default in Word's table look) was taken for Repeat as header row; a table crossing a page showed its first row twice. Only rows set to repeat are written so. The agendas round-trip to about 145 differing pixels (from 5,269 and 5,086), their text the same (`tables::only_rows_set_to_repeat_are_written_as_header_rows`) |
 | 2026-11-02 | trivial | ODT, found with LibreOffice's report templates and one-page résumé. A paragraph's padding on a side without a border (measured: LibreOffice gives it room) was dropped; it's kept, laid out (see layout-parity) and written back. Unequal columns (`style:column` `style:rel-width` and indents, on pages and sections) were made equal; they keep their widths, written back as shares, without the gap LibreOffice ignores them beside. Columns with no stated gap have none (it had been Word's 0.5 in). A paragraph starting a column (`fo:break-before="column"`) didn't; it starts with Word's column break, written back on the paragraph. The report templates round-trip to 0–11 differing pixels (from 9,600), the résumé to 24 (from 6,286) (`para_borders::padding_without_a_border_keeps_its_room`, `odt::tests::unequal_columns_keep_their_widths_and_columns_without_a_gap_have_none`, `odt::tests::a_paragraph_starting_a_column_starts_with_a_column_break`) |

A top-level list whose items nobody edited is written as read whole (a label followed by a space, picture bullets, an unnumbered header: what a paragraph's own markup can't say), a list going on with it naming it; a section may begin or end with a list, which then breaks there.

 Every element the ODF 1.3 schema (OASIS, Part 3, RELAX NG) defines, checked against what WordCraft's ODT reader and writer do with it. The question for each: does a file holding it open, and does a save without edits keep it? (See [file-format-parity.md](file-format-parity.md) for what WordCraft models; markup it doesn't model is written back as read while unedited: [odf-interpretation.md](odf-interpretation.md).)
