dtourolle	df741a8a49	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.	2026-09-07 20:00:40 +02:00
dtourolle	68ebf5d78b	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.	2026-09-06 19:01:48 +02:00
dtourolleandClaude Opus 5	a1165ef182	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.

dtourolleandClaude Opus 5	ce201c7dd6	Name the two spaces a photograph lives in, so a turn cannot go the wrong way ... Every orientation bug this codebase has had has been the same bug: a turn of the right size applied in the wrong direction. That failure is worth naming precisely, because it does not look like one — a quarter turn applied backwards lands 180 degrees from right, so the result is a plausible transform of the picture rather than anything obviously broken, and on landscape frames it is not wrong at all. It was the straighten shear, and it was the segmentation overlay, and each time it was found by eye rather than by a test. The reason it keeps happening is that "rotate 90 degrees clockwise" cannot be checked by reading it. The reader has to hold in their head which of the two images is being rotated and which way the y axis runs, and there were four hand-written copies of the permutation to hold it for: the shader prologue, its CPU twin, the thumbnail path, and the segmentation. So nothing added here says clockwise, anticlockwise, horizontal or vertical. The functions say *which space they take and which space they return* — `into_shown` and `into_stored`, `source_pixel` and `shown_pixel`, `into_shown_rect` and `into_stored_rect` — and each takes the dimensions of the space it reads from, so no caller has to work out which pair it is holding. `StoredRect` and `ShownRect` are separate types because they are the same four numbers meaning different things, which is exactly the case where a mistake is silent: a shown rect measured against stored dimensions produces a rectangle in the wrong place, not an error. Underneath there is one permutation. `source_pixel` was already shared by the prologue and the thumbnails; `source_point` is its normalised twin, written beside it so the two cannot drift, and everything else is those two read forwards or backwards. `Orientation::inverse` is the group inverse rather than `4 - turns`: mirrors apply after the turn, so undoing means undoing them first, and a mirror seen from the far side of an odd turn is about the other axis. That is the diagonal-mirror case, tags 5 and 7, and getting it wrong renders as — again — 180 degrees. Three call sites lose their own copy: the thumbnail path, `dr-ui`'s segmentation, and `dr-gpu`'s `local` example. "Upright" now means one thing across the application rather than one thing per caller. The gate that matters most is `the_render_and_the_orientation_map_agree`. The shader prologue and `Orientation` answer the same question by different routes, and until now nothing checked that they answered it the same way. It now checks every EXIF tag against every user rotation and mirror on top of it, because the composition is where the two could agree singly and disagree together. The rest earn their place by having caught something. Writing these found two real errors in this commit's own new code before it ran anywhere: `shown_pixel` was handed the dimensions of the wrong space and overflowed, and the rect map turned the wrong way for the diagonal mirrors. A round trip that returns what went in is the only check worth having here, since every wrong answer is still a picture. No behaviour changes. The permutations are the ones that were already being applied; they are simply applied from one place now.

dtourolleandClaude Opus 5	4a82753d22	Show the detector the photograph, not the sensor's scanlines ... "Find subjects" was handed the proxy in the sensor's own orientation, so every frame shot on a body held sideways reached the model lying on its side — and a model trained on upright photographs is very bad at those. Measured end to end on a 22 MP frame of two people and a dog: `person 0.36` and nothing else, against `dog 0.82, person 0.61, person 0.49` for the same pixels stood up. Nothing failed; the panel simply offered one poor subject where there were three good ones. The orientation was never dropped on purpose. The proxy is deliberately rendered through a *neutral* graph — the detection has to survive an exposure change, or every slider would invalidate the masks built on it — and neutral took the file's orientation with it along with everything else. Landscape frames were unaffected, which is why it stood for as long as it did. The turn is `Orientation::source_pixel`, the same function the grid's thumbnails already go through, so the detector and the thumbnailer now agree about which way is up rather than holding two opinions. What it is turned by is `Framing::effective_orientation` — the file's EXIF tag and the photographer's own rotations composed into one permutation, by the group law rather than by adding the turns, which is a distinction `Framing` already had to make and had already tested. Rotating the picture and pressing the button again therefore does what it looks like it does. The proxy stays in sensor space and the masks come back into it. That is not a detail to be tidied later: the generated shader samples the mask array at `uv_src`, *after* the framing map, so a mask stored upright would sit a quarter turn off the subject it was drawn around. That is a wrong mask rather than a weak one, and nothing announces it. So the picture is stood up for the model and laid back down for everything else, and `upright`/`lay_down` are returned as a pair because calling one and forgetting the other is silent. Both directions are the one function: `upright` gathers through `source_pixel` and `lay_down` scatters through it. A quarter turn is a bijection of the pixel grid, so the round trip is exact — no filter, no resampling, and no hole to fill — and an inverse written out by hand would be a second thing to keep in step, whose way of being wrong is a mask mirrored about the wrong axis, which still looks like a mask. The orientation joins the confidence and the tiling flag in the segmentation signature, and for the same reason: turning the photograph changes what the model recognises, so two runs either side of a rotation are different instance lists. Two that happened to come out the same length would otherwise share a signature and a stored layer would be silently re-indexed from one into the other. The refine pass had it too — it re-runs the model over a crop rendered in the same sensor space — so it makes the same turn, and would otherwise have handed back a worse mask than the one it was asked to improve, on the subject the photographer had just pointed at. `dr-gpu`'s `local` example is fixed with it. It exists to be the shipping path with pictures attached, and a diagnostic that reproduces the bug it is meant to catch is a trap for whoever reads it next. Seven tests. The round trip is the identity over all eight EXIF tags on a non-square asymmetric grid; a turn carries whole pixels rather than shearing the channels apart; a sideways frame reaches the model upright; a box comes back in sensor pixels, worked out by hand for the one turn a portrait frame actually writes; a restored box still reads low-to-high for every tag, since the rest of the pipeline takes `x1 - x0` without checking the sign; and the eight tags cannot collapse into one signature key. The existing composition test now runs against `effective_orientation` itself, over all 8 x 16 baseline-and-user pairs.

dtourolleandClaude Opus 5	5323608051	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.

dtourolleandClaude Opus 5	c75849040c	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.

dtourolle	ec713585a5	Measure the distance to the edge, and get four controls for one transform ... Feathering, growing, shrinking, closing and opening are the same number read differently. With the signed distance from the boundary in hand, dilation is the set where d >= -r, erosion where d >= +r, and a feather of any shape is a function of d. So the field is computed once and the controls are arithmetic on it. The **field** is what reaches the GPU, not a finished alpha, and that is the point: growing a mask or changing its falloff then costs a uniform upload and no recomputation, which is what makes them live controls rather than ones that stall on every drag. Only closing and opening rebuild, because after the first threshold the shape has changed and the old distances describe the old one. Exact Euclidean, via Felzenszwalb's separable transform — not a chamfer approximation, which leaves a mask visibly octagonal once grown more than a few pixels. A test asserts the diagonal is √2 rather than 1 or 2. It runs on the CPU, which ARCH §5.4 forbids for masks. The rule is about brush lag — a stroke rasterised per frame — and this is a different operation: once per mask edit, on input the model already produced here, producing a field the GPU then samples for free. What it buys is exact determinism, which matters because masks reach the sidecar as indices and a field that varied by vendor would mean a mask meaning one thing on the desktop and another on the phone. The half-pixel in `signed_distance` is not a detail, and a test caught it. Measuring to the nearest opposite pixel *centre* puts the smallest magnitude at 1 either side, so the boundary is nowhere and **eroding by less than a pixel removes nothing**. A control whose first notch does nothing is a broken control. Half a pixel off each side puts the boundary where it physically is, and eroding by 1 takes exactly the outermost ring. Every falloff curve is 0.5 at the boundary by construction, asserted for all five: changing the curve should change how the transition looks and never where it sits.	2026-08-22 08:39:17 +02:00
dtourolle	ee10097435	Mask the subject the model found, not the regions underneath it ... The watershed hierarchy does not survive a photograph, so local masking stops depending on it. A layer can now be one recognised object, and the object's own coverage is the mask. `Options::watershed` defaults off. It costs ~80 ms plus a full-resolution readback to produce a ladder that collapses, and paying that on every photograph buys a control that misleads. Kept switchable rather than deleted: the passes and the hierarchy are correct in themselves and it is the merge criterion that fails, which is a change to one function. Masks now rasterise in **source** space at proxy resolution and are sampled by the composed shader after the framing map. That fixes a real bug: they were rasterised in output space, so zooming slid the photograph underneath a mask that stayed pinned to the viewport, and cropping moved every adjustment to a different part of the picture. Doing it this way also leaves the framing map in exactly one place — a second copy in the mask shader would have been a second thing to keep in step, failing only when straightened. A subject is stored as identity, not pixels: the mask is megabytes and is reproducible by running the same model over the same image, so the sidecar carries the index, the class and the score, and the session carries the pixels. The class is there to be checked — if instance 3 comes back a "car" where it was a "dog", something changed and the layer is stale rather than silently masking the wrong thing. The overlay now draws instances and is transparent everywhere else. The region version covered every pixel and so hid the photograph it was drawn over; the question it exists to answer is whether an outline follows the subject, which you can only answer by seeing both. `examples/local.rs` is the worked example: subject in colour with the rest monochrome, and the subject lifted out of its background. Run on a 5472x3648 CR2 it finds two people and two cars, and the colour-pop keeps her hat and hair while the wall and grass behind go grey.	2026-08-22 08:39:17 +02:00
