 - [x] 12.14c Coloured slider tracks with double-click reset in Black & White, Color Balance and Hue/Saturation, filter sliders lined up (`6b709b4`, `c8ed9ba`, `0c969af`). A fix beyond Swift found by its tests: a sheet or Camera Raw group destroyed while an entry held the keys committed into freed members (`releaseFocus`). Codex review: passed in round 3; round 1 found Camera Raw groups still unsafe to destroy, Hue/Saturation's arrow keys stuck on rounding and right double clicks resetting, with test gaps; round 2 an untested repaint and two stale notes.
 - [x] 12.14d1 Colouring only the selected letters (`2bfc4ea`, `4503998`, `b5fe653`, `a1d56ac`): colour runs in the text style, the manifest's version 10, the runs drawn and kept through edits, the palette, picker and Type bar paint the selection, the swatch follows the caret, the selection stays see-through under the picker. Codex review: 3 rounds; round 1 found colours guessed onto the wrong twin letter (now exact steps through every path, undo included) and run glyphs drawn in the clear overlay, with test gaps; round 2 a coloured tail lost across multi-step edits and a preedit over a selection inheriting wrongly; round 3 a leading preedit losing its colour on update or commit and an untested start position; fixed and closed after the third.
 - [x] 12.14d2 Sampling keeping a panel's focus and the keys going back to open text (`810c88a`), filters, adjustments and Invert waiting for text editing to finish (`d448625`). Sampling's panel focus is a known difference: the window manager activates the clicked window, and refocusing at the press would end the sampling, so the keys go back at the release. Codex review: 3 rounds, test gaps only (reopened text, empty-layer Vignette, both pickers and the background's, the modal guard, a tool panel keeping its keys, no request without text); fixed and closed after the third.
-- [ ] 12.15 Version 1.3.3: the Dither filter.
+- [x] 12.15 Version 1.3.3: the Dither filter (`f3cd4e9`, `71635e2`, `d0aae29`, `09ab78a`): `DitherPixels.c`, `DitherSettings` with its styles, chunky pixels and their shape, colours and ASCII glyphs, the filter kind in the Filter menu under Bloom / Glow, full-size previews, the picker's two Dither colours, the sheet's controls and swatches, the busy line shown only for the slow filters; the guide's reload note (`29f0bea`); `e70da06` (a launch to open a file shows its window) judged. Codex review: 3 rounds; round 1 found the Characters field stale after normalization, canonically equal characters drawn twice and a stale test, with test gaps; round 3 found glyph paths filled odd-even (overlapping outlines lost their ink); the rest test gaps; fixed and closed after the third.
 - [ ] 12.16 Release OmaPhoto 1.3.3, the version Compositor carries (the user's decision, 2026-09-26: OmaPhoto's version follows Compositor's): README's features, AGENTS.md, the distro checks, packages, the install scripts rerun.
 - [ ] 11.5 End-to-end acceptance run with screenshots, README Linux section, `AGENTS.md` sync, MVP acceptance table.
