 - 12.5a work: the PSD reader, PackBits, vector masks and live shapes, the document builder, the session's Photoshop import with its sheet, the importer's filter, dropped pictures named and kept apart, the desktop MIME type. Evidence: every test green in the dev image, lint clean; statement deletion over every new and changed file, then targeted mutants for the survivors: all caught but the equivalents AGENTS.md names.
 - 12.5a round 1: FAIL, two findings. A file that opens but cannot be mapped (a pipe, a mount without `mmap`) was refused where Swift reads it (read when the map fails, a pipe tested); the folder's place beside an active layer inside a folder passed its test broken (pinned). Beyond Swift, recorded and fixed for the twin's graph rule: a clipped folder took a link the store refuses (no link now, the base note). AGENTS.md's log categories read `omaphoto`.
 - 12.5a round 2: PASS. Its residual: a read failing after the open is named untested in AGENTS.md (Qt 6.4 refuses to open a directory, probed).

+- [x] 12.5b Version 1.2.0, part two: the Outer Glow effect, brush Smoothing, and the release's other changes to what the twin holds.
+- 12.5b work: the Outer Glow effect (model, manifest, kernel, margin, surface, preview cache, sheet, session), the previews kept while an effect is hidden, brush Smoothing (session and bar). Evidence: every test green in the dev image, lint clean; statement deletion over the changed code and targeted mutants: all caught but the equivalents AGENTS.md names.
+- 12.5b round 1: FAIL, two findings. The notes TASKS.md 12.0 assigned here were unwritten: Swift agrees since 1.2.0 on Levels' soft edges (`f6a74c9`), effects through snapshots (`5775dd1`, `6230e41`), Color Dodge and Burn in sRGB (`121a15f`), M and L (`b5cb4fa`) and Select All (`90ee29f`), each note now saying so; the signal record lacked `smoothing` (read now).
+- 12.5b round 2: FAIL, two findings. Select ▸ All rested without a canvas where Swift 1.2.0's never rests (`90ee29f`): the entry is always enabled now and selects a focused field's text (tested); the 9.4a note on Swift's Gaussian test was stale since `7c4512a` (says so now). With them, as `7c4512a` did, the invert test lost its wall-clock budget, which measured the parallel suite's load.
+- 12.5b round 3: FAIL, one finding, the third and last round. With the layer list focused, Swift 1.2.0's Select All reaches its table, which selects every row with the top one primary; the twin selected the canvas. Fixed after the round: a focused list takes Select All (`NativeLayerList::selectAllRows`), tested, its two mutants caught (`mut-12.5b-r3.log`); the item closes on that, the review's three rounds spent.
 - [ ] 12.6 Version 1.2.1: camera RAW import through LibRaw with its develop step, middle-button pan, persistent tool settings, Auto Select picking the foreground layer, the reshaped app icon (`45ab8fd`) in `packaging/icons`.
 - [ ] 12.7 Version 1.2.2: Photoshop's remaining blend modes in its groups; Black & White, Color Balance and Invert adjustments.
 - [ ] 12.8a Version 1.2.3, part one: the Camera Raw filter's model and pixel kernels.
