Let one mask be built from more than one selection, and paint into it
A mask the model draws arrives approximately right — stopping inside a shoulder, leaking into the hair — and FR-DEV-3's edge controls move the *whole* boundary, so no value of feather or dilation fixes two errors that go opposite ways. What fixes them is a second selection joined to the first, and a layer that held exactly one source had nowhere to put one. The brush the core has had all along was reachable from no control in the application. A layer is now an ordered list of parts. Each names a source and how it joins the mask before it — added to it, or taken out of it — and carries its own edge treatment, because a model's soft coverage and a stroke painted where it stopped short do not want the same feather. Invert and opacity stay on the layer, where the composed shader already reads them. The sidecar grows `[part]` blocks and nothing else. A layer of one part writes exactly the bytes it always did; a mask block with no part blocks after it reads back as one part; and a stroke, a join or a source this build cannot read costs that part rather than the layer. So every sidecar in every library still parses to the edit it always was. On the device the parts fold into the layer's one slice, so eight layers still cost eight channels: union is a `max` blend and subtraction is the erase blend the brush already used. A part is drawn into a scratch texture before it is joined, and that is not incidental — an erase stroke means a hole in *that part*, not a hole in the mask, and drawn straight onto the accumulator it would punch through the subject underneath. A layer of one part skips all of it and takes the path it always took. In the interface: a part list under the selected layer with a chip saying which way each joins, Add and Subtract beside it, a Select/Paint/Erase strip with the brush's size, hardness and flow, and a drag on the photograph that paints. Pressing Paint on a mask that cannot hold a stroke joins a part that can, rather than explaining that a subject is not a brush. A whole stroke is one step in the history. The edge controls now shape the part that is selected rather than the layer, which is the one behaviour change to an existing control: with a correction selected, the feather slider softens the correction and leaves the model's mask alone. |

Let a mask start from a tone or a colour, not only a shape
Every local adjustment began from a shape: painted, drawn with a handle, or found by a model. So the only way to hold back a sky was to draw a line near where it ended, and the only way to warm skin was to paint round it — both of which put the edit's edge where the photographer put a gesture rather than where the picture changes. A gradient across a treeline halos, and an adjustment traced round a face stops on the outline of a hand. MaskSource grows two variants that select by what a pixel *is*. Luminance carries two bounds on the perceptual tone scale plus a softness; Colour carries an arc of hue, a range of chroma, and one softness for every edge of both. Five floats and three, so they diff, sync and merge per field under FR-NC-9 exactly as a gradient's geometry does — the property a stored raster has none of, and the reason the model's coverage had to sit beside its source rather than inside it. The pixels are the shader's business and nowhere else's. `mask.wgsl` takes the demosaiced source as a sixth binding and two new modes read it: decode, balance, pull a clipped photosite back to neutral, apply the camera matrix, then weigh the band. Nothing crosses to the CPU but the numbers and the matrix, and each mask texel averages its own footprint in the source, so a band lands on the tone an area is rather than on whichever texel a proxy grid happened to land on. The photograph it measures is the one the camera recorded, before this edit. A band over the edited result would slide out from under the edit as the edit was made — raising the highlights would change which pixels counted as highlights, and the slider would chase its own mask. Feather, falloff and morphology stay off a range layer, which is what `shapeable` already meant. All three are functions of the signed distance from a boundary, and a range has no boundary to be at a distance from; its edge is the softness of its own band, in the band's units. Offering them would be four controls that move and change nothing. |

Put the coordinate-domain lens corrections into the graph
`lens.rs` has held a `Warp` trait, a composer and two implementations — distortion and lateral chromatic aberration — since they were written, and `compose_warps` was called by nothing outside its own tests. The corrections existed, were correct, and never touched a photograph. `EditGraph` now holds them, and `compose_full` emits them between the framing prologue and the fetch. Distortion first, then CA: each warp receives the position the previous one produced, and lateral CA is a magnification about the optical axis of the *undistorted* frame, so measured on a barrel-distorted one it would be fitted to a radius no profile describes. They reach the panel the way framing already does — through `capabilities`. That was the one open question and existing practice answered it: framing is also not an `Operation`, also has parameters a photographer sets, and also arrives through that list. Because `Preset::capture` walks the same list, the sidecar, the clipboard and the undo stack carry a warp's parameters with nothing registered anywhere, and no file under `ui/` names one (FR-DEV-3a). `state()` destructures `EditGraph` field by field precisely so that a new field cannot be forgotten, and it was not. Chromatic aberration is the only thing that samples per channel, and `splits_channels` is what keeps everything else from paying for it. Red and blue are fetched from positions green is not — green is the reference and never moves, so a wrong correction still leaves one channel sharp rather than softening all three. With no CA in the chain the single-fetch path is emitted instead. The interpolating sampler is now chosen by framing *or* an active warp. Asking framing alone would have nearest-neighboured a distortion correction on an unstraightened frame, and that aliasing reads as a bad profile rather than as a missing filter. The warps go in the geometry invalidation key rather than the colour one: they decide which source pixel a colour is read from, so a tile cached across a distortion change would keep drawing the previous correction. The pipeline cache needs nothing new — `hash_source` already covers the generated body, and uniform values never enter it, so arming a warp recompiles and dragging it does not. Both are asserted.

Draw the repairs, before anything sharpens what they removed
A spot set now composes detail passes of its own, one per round, and they go ahead of every operation's kernel. That placement is the decision worth recording: a sharpening pass reads a neighbourhood, so sharpening a dust mark before removing it smears its edge into pixels the repair's disc does not cover, and what survives is a faint over-sharpened ring around an otherwise perfect patch. It also disagrees with ARCH §5.2, which draws spot removal after clarity — docs/spot-removal.md §5.1 is where that is argued out. Every length reaching the shader is in render pixels, converted here where the framing is in scope. Both the centre and the source go through `Framing::output_at` — the same map the fused pass applies to every pixel — so a rotated photograph rotates the offset with no trigonometry, and the radius is found by mapping a point one radius above the centre and measuring, rather than by multiplying by a ratio this function has no business knowing about. The tests turn and crop the frame and expect the mark to stay gone, which is the property that arrangement buys. compose_full now takes the spot set, because a photograph with a repair and no sharpening still has a detail stage: a fused pass that encoded its own output there would quantise twice and bind to a texture of the wrong format. compose_detail_for takes the source size for the same kind of reason — a RenderScale describes the region on screen, and a spot is stored against the photograph.

Format the tree the way the gate asks for it
`cargo fmt --check` is a required step and had drifted across 45 files. Most of it arrived this week: several operations were written in parallel worktrees and merged by hand, and a hand-merge resolves conflicts without ever running the formatter over the result. No behaviour changes — this is `cargo fmt --all` and nothing else, kept as its own commit so the next reader can skip it wholesale rather than search it for one that matters.

Give a gradient the angle it was asked for
A linear mask at 45° was not at 45°, and a radial with equal radii was an ellipse. Both on every photograph that is not square, which is all of them. The geometry is stored in normalised coordinates so that a mask survives a crop, a zoom and an export at another size — that part was right. What was wrong is that a *distance* was being measured in those coordinates too, and a fraction of the width is not the same length as a fraction of the height. So `dot(uv - centre, axis)` measured the ramp in a space one of whose axes is squashed against the other by the aspect ratio, and the iso-lines came out sheared: on a 3:2 frame a ramp asked for at 45° arrives at about 34°. Nothing announces it. The stored numbers are exactly what was written, the shader is doing exactly what it says, and the only place the fault exists is between the photographer's intent and the picture. It has been invisible so far because there is no way yet to place a gradient by eye — the handles that make it visible are what turned it up. So distances and angles move into the frame's own isotropic units: y spans `0..1` and x spans `0..aspect`, which makes a circle round and 45° a real diagonal. The centre stays a plain fraction of each axis, because it is a point and a point has no such problem — and because that is the space a click arrives in. `frame_delta` is the one conversion and must stay the only one; the mask array's own dimensions carry the aspect, so it costs no uniform. The sidecar format does not change. What changes is what the numbers mean, and the only geometry in the wild is a default that has never been movable. The two tests are at 96×64 rather than square, which is the whole point: on a square target this bug cannot be reproduced, and every existing mask test was square. Both fail without the conversion — the radial reaching 28px sideways where it reaches 19px down, and the diagonal landing on the wrong side of the line it is supposed to lie along.

Apply the masks to the thumbnail and the export, not only the screen
Reported as a thumbnail bug; the export had it too, which is the serious half. You would have exported a photograph missing every local adjustment. Both called the unmasked `render`, and the failure is silent by construction: the generated shader always declares the mask binding and always emits a block per active layer, so binding the empty placeholder multiplies each of them by zero. No error, no warning, no missing texture — the adjustments are simply not there. From inside either path there is nothing to see. Every path that produces pixels now goes through one helper that binds the array, and that is the point of it being one helper rather than three correct call sites. The array is rasterised in source space at proxy size and sampled through the framing map, so one array serves every output size: a 256px thumbnail and a 24 MP export bind the same texture. Three tests, and the first is the fault stated directly — render the same edit with and without the array and assert they *differ*. If binding it ever stops mattering, the masks have stopped reaching the shader. The third checks the masked share of the frame is the same at 32px and 128px, because "both non-empty" would pass while a mask that scaled wrongly still ruined every thumbnail. |
