 - [x] 12.10c Part three: crop ratios 3:4 and 9:16 (`8b5a6af`) and a crop that starts at the selection (`5ece82b`); Vignette round by default, an empty layer painted across the canvas (`0488cab`); text colour previews from the pickers (`3317d02`, `4e5f4ec`); the tab strip's steady edge fade (`1fb6a3f`) and the title bar's free space dragging the window (`e8ed83b`), each where the twin has its subject. `c4244c4` is reverted in `67301d2`; the format documents (`156c38c`, `4455a72`) are 12.13's. Codex review: 2 rounds, PASS. The tab strip's two commits have no subject here (no fade; the desktop's title bar drags).
 - [x] 12.11a Versions 1.2.8–1.2.10, part one: the document's own pixel budget, scaled to the machine's memory, one surface capped (`7dadc88`, `bc865fb`); marching ants from a screen-resolution outline when zoomed out (`8eba077`); Camera Raw's grading wheels drawn in the direction their hue runs (`96edd5f`). Codex review: 3 rounds, PASS.
 - [x] 12.11b1 Part two: Photoshop Large Documents (`b8e3cd1`), background-only PSD and PSB from the merged image (`e6bcfa1`), oversized layers cropped to the canvas (`1fcf854`). Codex review: 3 rounds; the third stopped before its report after one finding (a layered read copied the ICC resource), fixed and closed.

+- [x] 12.11b2 Part three: simple Photoshop text as editable text (`b8cce6e`, `fa2b342`). Codex review: 3 rounds; the third's findings (test gaps: rounding, scaled leading, the `Txt` key, negative exponents, versions, the limits' edges) fixed and closed.
 - [ ] 12.11c Part four: clicked text starting on its first baseline, the pointer kept while typing (`292cb6b`, `072fa08`); live text opened by a double click with the Move tool (`a5721b2`); SVG import through Qt SVG (`0534e00`).
 - [ ] 12.12 Version 1.2.11: masks painted anywhere on the canvas, moved unlinked masks under effects, effects kept on screen while text is edited, masks painted and steps undone (`b683acb`), mask thumbnails' ground, text shown as its committed pixels, numeric label scrubbing.
 - [ ] 12.13 Version 1.3: reloading a project changed on disk (`ed5ddea`, merged in 1.3), its manifest-and-sizes fingerprint (`cd4061a`), editing while a project saves, images decoded from memory, the guide for AI agents writing projects.
