 ## Progress log
+- **2026-10-16 (M10, #2269):** Exported images come out in the colours the page shows. Export all images, Save Image As and Word export converted CMYK with (1 − c)(1 − k) instead of the renderer's CMYK profile (cyan ink came out as (0, 255, 255) where the page draws (0, 174, 239)) and ignored ICC profiles (an Adobe RGB or Display P3 image came out as if it were sRGB). They now convert through the renderer's own conversion (vendored hayro-interpret patch 39, `pdfcraft_render::cmyk_to_srgb` and `IccProfile`), and CMYK JPEGs and JPEGs with an ICC profile the file doesn't carry are written as PNG in those colours. CalGray, CalRGB and Lab images are still missing. Estimates unchanged.
 - **2026-10-15 (M2, gap 12):** `cargo xtask text-oracle` scores reading order as well as word F1: the longest common subsequence of the two word sequences over the longer one. F1 is a bag of words and cannot see order at all -- measuring #2431, a change that moves text and nothing else, it called 26 of the 29 files whose output changed identical, where the order score separated 18 improvements from 6 regressions. Reports, does not gate; a disagreement with Poppler, not a verdict. Estimates unchanged.
 - **2026-10-15 (M2, #2305 follow-up):** WinAnsiEncoding 0xA0 and 0xAD and MacRomanEncoding 0xCA extract as the ordinary space and hyphen Annex D.2 names them, in the vendored hayro tables (patch 30) as well as `crates/fonts`, so search, copy and redaction see characters that were hidden behind U+00A0 and U+00AD. Across the pdf.js corpus the soft hyphens we extract fall 117 to 13 and the non-breaking spaces 30 to 26; the rest come from `/ToUnicode`. An explicit `/Differences` name keeps its glyph list value, as pdftotext does. Estimates unchanged.
 - **2026-10-13 (community, M3, #1569 review):** Pixel-only Wayland wheel, wheel-tilt and continuous input use standalone moved events, so Ctrl zoom does not remain latched after the modifier is released (#991); vendored winit patch (13), with a policy test. Estimates unchanged.
