 - 13.5b review (Fable 5.1): round 1 FAIL (the picker's Cancel turned Light Gray, Light Blue and Green into Custom, since only one side was compared in 8 bits; the drawing's dots, dashes, caps and 4-point threshold loosely tested); round 2 PASS. The CPU cap was lifted to all 32 cores during this item (scripts/mutate.py follows).
 - [x] 13.6 Part five: Ctrl+Z while typing takes back what was typed (`ee68ba9`); font previews in the Type bar (`1bd1df4`).
 - 13.6 review (Fable 5.1): round 1 FAIL (four survivors unrecorded; the code judged right against Swift); round 2 PASS.
-- [ ] 13.7 Versions 1.3.6–1.3.7: New Canvas presets in a More menu (`aaf3dc0`); the project's Quick Look preview (`14aad18`, `4868465`) judged: the package's preview file is format, Finder's thumbnail extension is macOS alone.

+- 13.7 port (agent): tests in `NewCanvasSheetTests` (presets, the check, the dots), `QuickLookPreviewTests` (the store's folder, load ignoring it, the JPEG byte for byte, sizes, the 50-megapixel bound, a failed render, a controller save) and the sync order in `ProjectReplaceTests`. Survivors recorded: the heading's stretch (equivalent); the scale and allocation null checks untested. No review yet.
 - [ ] 13.8 Version 1.4, part one: the changes behind the GPU canvas that the CPU canvas and export share: a sharper canvas with adjustment layers (adjustment surfaces at device resolution, adjustment operations scaled with the surface, direct sampling for an upright layer at 1:1, tiled layers included) and the PSD adjustment and mask fixes (`8c0417b`); Photoshop's positive Saturation (`fe7a83d`); Levels and Hue/Saturation on all cores (`af3b568`); a blur's preview kept while the layer grows (`3ccc125`); the hierarchy kept until what shapes it changes (`d0135c8`, `dcf1c66`).
 - [ ] 13.9a Part two: blending. Clipping stacks and live-mask coverage at device resolution; an adjustment in any mode over the document and inside a stack, blended at full coverage, its alpha restored, then mixed through mask and opacity (`6dc2219`); a clipping stack composited in its base's mode in every mode, on the canvas, in export and in Copy Merged (`8ab32c9`; Qt keeps the stack's mode: a held judgment to prove); Soft Light by Photoshop's formula as Core Image computes it, on the canvas, in export and in Copy Merged (`5a8f6ce`: a 0.9 source over a 0.5 backdrop gives about 170; compare Qt's formula first); soft, partly clear painted layers blending alike in Soft Light, Overlay, Multiply and Color Dodge (`e6c964b`, `softEdgedLayersBlendTheSame`).
 - [ ] 13.9b Part three: the Metal canvas (`cdf8674`, `4b04323`, `5708ed3`, `93de9e7`, `54dd707`, `91cb0b1`, `f773f7b`, `4c5e1a6`, `d04f159`, `b1b7490`) stays CPU (the port's decision); each contract its tests hold for every canvas is judged and, where the twin lacks it, ported: Grain and Add Noise anchored to the document while panning and zooming, the canvas mapping its surface back to document coordinates (`54dd707`; the twin's adjustments take view-space regions today); every adjustment kind with alpha, own and folder masks and opacity, blurs at the drawn scale and direction (`54dd707`); a moved or duplicated selection's preview and commit (the hole cut only for a move, the rounded offset, opacity and coverage once) and the lazy tiles realised before display and commit, a failure cancelling the move with `brushError` (`4b04323`); live paint, erase and mask paint replacing patch interiors, revealing paint past the old bounds under the old mask, gradients' selection clip and opacity matching the commit, the lazy gradient fill realised before display and commit, Smudge and Liquify previews keeping mask, opacity and placement (`5708ed3`, `91cb0b1`); a new one-pixel white mask revealing its whole layer, rotated or scaled without a faded edge, and the live paint grid's extent kept (`93de9e7`); rotation, flips and scale, sharp successive reductions, premultiplied blending in every mode with layer and ancestor opacity, the checkerboard anchored to the document, the crisp composite at high zoom (`cdf8674`); non-adjacent live mask sources, distortion previews (perspective, folded, flipped, placed masks, effects), text previews keeping effects and handing them on without a flash, new drafts above the active layer inside a clipping stack, lines above the image, effects and placed masks kept while brushing, painting masks, dragging gradients and moving pixels (`f773f7b`); sharp reductions and fresh paint pixels (`4c5e1a6`, `d04f159`); `b1b7490` only words a test's diagnostics. Also named, each to judge: sampling modes and rounded-up reduction extents, premultiplied blending in sRGB, the surround, shadow and border, placed own masks and multiplied folder masks on ordinary pixel layers, and filter, Levels and Hue/Saturation previews replacing the layer's pixels with its alpha, mask, opacity and placement (`cdf8674`); image-edge sampling that carries edge values outward for filtering and keeps the image's own boundary, for ordinary images and live grids as for the white mask (`93de9e7`); adjustment results equal to the CPU reference, deterministic Noise and Grain seeds, Add Noise counted in frame pixels from the document's corner and Grain's size in document pixels (`54dd707`); a lazy gradient fill that fails cancelling the gradient with `brushError`, and a failed commit publishing it (`5708ed3`); Smudge and Liquify strokes and commits equal to the CPU algorithms (`91cb0b1`, `matchesTheCPU`: the twin's CPU path is the reference, a held judgment); new text shown when the active layer cannot draw, the pixel grid and the new text frame drawn above the image and passing input through, and edits keeping mask gray values and effects and placed masks as paint bounds grow (`f773f7b`). Texture retention, eviction and blits are GPU mechanisms with no CPU twin.

 - [ ] 13.11 Version 1.4.1, part one: why a brush can't paint, Select All then Inverse deselects (`133c34a`); painting at the layer's own resolution (`d3170ab`): Clone Stamp and Blur sample there, the Brush and eraser on a scaled-down, rotated or unequally scaled layer that holds pixels lay a tip of the layer's own pixels and show a smooth edge scaled back up, while an empty layer, however small its transform, paints at document resolution (`paintingABlankLayerThatWasScaledDownPaintsAtDocumentResolution`); the twin's coverage in the stroke's grid (`BrushStroke::grid`, `BrushCoverage::render`) may already hold both, a held judgment to prove with `NativeResolutionPaintTests`' cases; Cancel and Apply only when an edit waits, scaled layers' scale (`67cc31e`).
 - [ ] 13.12 Part two: masks as Photoshop's: the button reveals the selection, Alt-click shows a mask alone (`b3419ab`).
 - [ ] 13.13 Part three: Ctrl flips Auto Select both ways and Shift the aspect lock, live in the bar (`bca8f13`, `03d692c`); Move bar values apply without Apply as one step (`686d8c7`); resize handles snap (`c459f88`).
-- [ ] 13.14 Part four: tabs drag to reorder, the ones that don't fit gather in a menu (`1faf7a0`).
-- [ ] 13.15 Part five: Layer › Ungroup Layers (Ctrl+Shift+G) and in a folder's context menu (`1318f1e`, `6c3b9a5`); Alt over a mask thumbnail shows the duplicate pointer with an eye (`6955a6f`).
+- [x] 13.14 Part four: tabs drag to reorder, the ones that don't fit gather in a menu (`1faf7a0`).
+- 13.14 port (agent): tests in `ProjectTabLayoutTests` (Swift's six and the bounds), `ProjectTabDragTests` (drag, slide, stacking, landing, threshold, busy, lost release, a close mid-drag, the overflow pill and its menu), `ProjectWorkspaceTests` (`moveTab`) and `ProjectWorkspaceViewTests`. Survivor recorded: reporting `ended` after a click that never dragged (equivalent but after a lost release); `span`'s empty guard and `contentWidth`'s pill fallback removed as dead. No review yet.
+- [x] 13.15 Part five: Layer › Ungroup Layers (Ctrl+Shift+G) and in a folder's context menu (`1318f1e`, `6c3b9a5`); Alt over a mask thumbnail shows the duplicate pointer with an eye (`6955a6f`).
+- 13.15 port (agent): tests in `GroupSessionTests` (Swift's three and more), `LayerContextMenuTests`, `CompositorMenusTests`, `KeyboardShortcutsTests` and `LayerDragGestureTests` (the eye pointer). Survivor recorded: the context entry gated by `canEditLayers` (equivalent: the right-click makes the folder active); Swift's validation guard left out as dead. No review yet.
 - [ ] 13.16 Versions 1.4.2–1.4.3: Liquify keeps pixels sharp (`7164dd4`), Smudge without ghost copies (`ad9ad7c`), the Blur brush's own Radius (`504129d`), Blur, Smudge and Liquify on big canvases (`095da2f`).
 - [ ] 13.17 Version 1.4.4: quit works mid-gradient or with a dialog open (`1aad384`); Dither › Scanlines (CRT) on all cores (`9c99853`, `cd2f998`).
 - [ ] 13.18 Version 1.4.5: Camera Raw curves as Photoshop's (`60d9117`): the smooth parametric curve and the per-channel point curves, Refine Saturation's new meaning (0 the RGB curve, −100 brightness alone, above 0 stronger colour) and its words; the graph: a press picks a point, divider or tonal region once and keeps it through the drag, a region drag lifts or lowers that region, dividers move in the bottom strip and stay ordered, point mode picks by distance, adds and drags a new point at once, keeps inner points ordered and moves the end points' outputs alone, the chosen point lit and the readout following it, a new channel or preset clearing the choice.
