 - [x] 13.2 Version 1.3.4, part one: a font change applies to the selected letters, a mixed selection takes the face the menu shows, the menu says (Multiple) (`0eaeb98`, `1ffc8f4`, `916d1ab`, `bc29006`'s test), with the manifest and both format documents.
 - 13.2 work: `LayerTextFontRun` and `fontRuns` with Swift's model (`fontNameAt` for `fontName(at:)`), the run members moved to `TypeTool+Runs.cpp`, each run's face as a layout format, format version 11, (Multiple) in the Type bar's menu; a fix beyond Swift keeps a folded base face. Tests: `TextFontRunsTests`, `TextFontControlsTests`.
 - 13.2 review: round 1 (codex) FAIL: the folded face's parity unstated, and test gaps (overflow, start-of-text inheritance, newlines, an independent bold reference, editor geometry); round 2 (codex) FAIL: test gaps (neighbouring faces, size and tracking in layout, colour with faces, a missing location); round 3 (Fable 5.1) FAIL: test gaps (a negative location, a run starting at the span's end, fractional numbers, an unlisted face's own name). All fixed, each mutant caught; closed after the third round.
-- [ ] 13.3 Part two: Dither's ASCII as readable text (`2309a85`, the kernel and the sheet); Select › Color Range (`c3e360a`: `ColorRangeSelection`, `WandPixels.c`, the sheet, the canvas's sampling).
+- [x] 13.3a Part two: Dither's ASCII as readable text (`2309a85`, the kernel and the sheet).
+- 13.3a review (Fable 5.1): round 1 FAIL (test gaps: the face's divisor and the width's rounding at larger sizes, the coverage's mean, the Text Size row's ends, decimals and unit, the picked table over non-square cells); round 2 FAIL (the kernel's averaging window, height and width); round 3 PASS.
+- [ ] 13.3b Part three: Select › Color Range (`c3e360a`: `ColorRangeSelection`, `WandPixels.c`, the sheet, the canvas's sampling).
 - [ ] 13.4 Version 1.3.5, part one: Export JPEG and Canvas Size take the app's colour picker (`c580a38`); Export JPEG's zoomable preview and tidier layout (`ac6f309`); `908bed9` and `158cd53` judged (Swift concurrency and warnings).
 - [ ] 13.5 Part two: the marquee, shapes and a moved selection snap to View › Snap To (`d6e3e93`, `8b1369a`); View › Grid Settings… with Restore Defaults (`1c819d0`, `db5eafa`).
 - [ ] 13.6 Part three: Ctrl+Z while typing takes back what was typed (`ee68ba9`); font previews in the Type bar (`1bd1df4`).
