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. |

Group the panel by what operations say they are about
A strip of groups over the adjust panel — Light, Colour, Detail — derived from the attributes the operations declare. `adjust.slint` names none of them: the strings arrive resolved and the panel only draws them, so a new operation joins the right group by saying what it is and this file does not change (FR-DEV-3a). A group nothing carries is not offered, so a tab never opens onto nothing. Geometry is left out because its one operation prefers an on-canvas widget and is skipped by the row builder — a Geometry tab would be empty while `GeometryPanel` holds the real controls. The strip appears only when there is more than one group to choose between; a single tab is a control with one option. The selected group is underlined rather than filled. The accent means *modified* everywhere else in this interface, and spending it on "which tab" would blunt the one signal the panel has. **The trap, and it nearly bit again.** `op_index` on a row counts over every capability, not over the ones a filter kept — it is how a row routes back to the core. Renumbering it while filtering would make a slider drive a different operation, which looks like a rendering fault rather than a routing one. `rows_filtered` keeps `enumerate` over the full list and only `group_head` is a position within the emitted rows; a test moves a value through a filtered row and checks it lands where it was asked to. Six tests, including that a nonsense index falls back to showing everything rather than to showing nothing. |

Let an operation say what it is about, so the panel can group without naming
Tool tabs need a taxonomy, and the taxonomy was the problem: a table in `ui/` mapping operation to tab breaks FR-DEV-3a, and a `group:` field risks what `ui-refinement.md` condemned `starts-group` for — the core deciding where the panel draws things. `Attribute` threads the needle. It says what an operation *is* — tone, colour, detail, optics, geometry, effect — which is the same category as `ParamKind` and squarely on the core's side of ARCH §4.3a's line. What is drawn, where it sits and whether it is visible stay the frontend's. There is no attribute for "the third tab", the enum's order is declaration order rather than screen order, and a frontend may render these as tabs, as headings, or ignore them. The payoff is that a tab strip can be *derived*: the groups are the attributes present in the capability list, so the interface names no operation and needs no table to keep in step. An operation joins the right group by declaring what it is, which is the one thing its author is well placed to say. Plural, because the tone curve is genuinely both — an RGB curve is tonal and the per-channel curves are chromatic, and filing it under one would hide it from half the people looking for it. Required and non-empty, enforced in `build.rs`, and the failure was checked by removing the line rather than assumed. An operation with no attribute is invisible to a panel that groups by them; a build that stops costs ten seconds, a control nobody can find costs more. The vocabulary is closed for the same reason: a typo would otherwise invent a category holding exactly one operation, which looks like a deliberate one until somebody counts. Six tests over the real chain, including the hand-written operations that `build.rs` never sees and so cannot check. |

No phone, so stop designing for one
Targets are a 12-inch tablet and a desktop (D15). That removes most of the navigation question rather than answering it. `EXPANDED_MIN_WIDTH` is 820 logical pixels and a 12-inch tablet is ~1024 across in portrait, so both orientations of both targets are the expanded class. The compact class now fires only when a desktop window is dragged narrow — graceful degradation, not a second interface. The bottom tool strip and the one-tool-at-a-time sheet were solving a phone, and there is no phone. What survives is input, not size, and the architecture had already decided it: `WidgetDemand::precise_pointing` exists for a television remote, and its own documentation says touch is fine because hit regions grow to the modality. Touch changes hit regions, not layout. The rules that fall out are worth stating because they are easy to violate by accident — no hover-only affordance and no modifier key may be the sole route to anything, since a tablet has neither. Local masking already lost its shift-click extend for exactly this reason. The guaranteed-wide viewport also pays for a better answer to the extent problem than hiding things. The complaint was never that the column is long; it is that the histogram scrolls away from the sliders it reports on. Collapsing shortens the scroll, pinning removes the problem, and ~260px of fixed height is affordable on a viewport that is never under 820 wide. |

Work out where things go, now that there are many of them
Local adjustments took the develop column from four panels to six, and the operation set is meant to keep growing — FR-DEV-3 still lists texture, clarity, sharpening and noise reduction as v1. But the count is the lesser problem. The real one is that local adjustments introduced a *mode* without introducing a way to see it. Selecting a mask silently re-points thirty sliders at that layer, and the histogram those sliders are judged against goes on reporting the whole frame. I built that, and it is the fault that loses work rather than merely slowing someone down. Decided: local becomes a mode, in the sense `crop-mode` already is. The app has the pattern, the user knows it, and it removes the ambiguity by construction instead of describing it in a caption. It also inherits the Escape/back stack that already leaves the innermost state first. Recommended: diverge on **width**, not on platform. A tablet in landscape wants what a desktop wants and a narrow desktop window wants what a phone wants, so `cfg(target_os)` would give one physical situation two answers. `apply_layout_class` already classifies on width and already remembers a per-class override; this is a second consumer of a decision the app makes anyway. What must not diverge is the controls — both layouts consume the same generated capability model, so a new operation still needs no UI edit. Left open, because it is taste: whether the wide layout eventually gains tool tabs. Recorded rather than left to be rediscovered is the *legitimate* route to them — a descriptor declaring an operation's nature, the same shape as `Affects`, with the frontend free to render it as a tab or ignore it. Deferred because ten operations do not need eight tabs and the field is easy to add later and awkward to remove. Surveys what Lightroom, Capture One, darktable and the phone editors actually do, including the thing none of them do: make a mask a panel that rewires a different panel. |

Keep the overlay on the photograph when the view moves
The overlay is a source-space picture; the canvas beside it shows whatever the crop, the zoom and the pan selected out of that same space. Drawn whole it stayed frame-sized while the photograph moved underneath, so zooming in left a map of the whole picture stretched over a detail of it. It now reports the visible rectangle as a clip, which the compositor applies for nothing. Resampling on the CPU instead would mean rebuilding a megapixel image on every frame of a drag, and putting it on the GPU would add a second texture to keep in step with the view. Pushed from the render path rather than the panel's sync: a pan changes no mask and no row, so nothing else needs to run, and rebuilding the row models on every frame of a drag would be waste. Straightening is handled by rotating the image. A quarter turn or a flip permutes the axes and a clip rectangle cannot say that — noted where it happens rather than left to be discovered. The proper fix is to run the overlay through the same shader prologue the photograph goes through, which is the right answer and a larger one than this. Four tests, and the one that matters asserts the clip *narrows* when zoomed — which is precisely what it failed to do. |

Take the watershed out of the product path
It does not work on a photograph, so nothing should offer it. `Segmentation` is now one model pass and what it recognised: no region field, no merge tree, no label upload, no granularity slider, and no readback of the whole proxy to build a graph that collapses. A click means "the object under the cursor". The region-selection path went with the hierarchy it indexed — including the shift-click add/subtract, which has no meaning for a whole object and would have been a modifier that silently did nothing. The passes, the hierarchy and the semantic prior stay in `dr-gpu` and `dr-segment`, tested and documented. It is the *merge criterion* that fails — the saddle is the minimum gradient along a boundary, so one weak pixel merges two regions and real gradient noise puts a weak pixel on every boundary. That is one function to replace, and the evidence for replacing it is worth keeping. What is gone is the wiring, the option, and the control that offered a user a choice with no outcome. `MaskSource::Regions` remains in the pipeline: it is tested, it round-trips through the sidecar, and a stored layer that names regions must still load and be reported stale rather than failing to parse. |

Put the edge controls where the mask is
Feather, falloff, grow/shrink/close/open and their amount, on the selected layer. All four read the one distance field, so all four are live — nothing recomputes except a compound morphology, and the session keys on that separately so a feather drag rebuilds nothing. Shown only for sources that go through the distance field. A gradient carries its own falloff in its geometry, and offering a second one would be two controls fighting over the same edge. Picking an operation seeds a small amount if none is set. Selecting "Grow" and seeing nothing happen would read as a broken control rather than as a radius of zero. |

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. |

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. |

Give a mask an edge treatment, and find out the watershed has none worth having
Two things, and the second is why the first matters more than expected. Mask layers gain a feather, a falloff curve and a morphology, all defined against a signed distance from the boundary rather than as separate features — one exact distance field answers "how soft" and "how far" at once, so dilation is a threshold at -r, erosion one at +r, and closing and opening are one of each in sequence. The compound pair costs a second distance field, which is why they are named rather than presented as a radius that happens to be signed. Types, defaults and sidecar round-trip only; the field itself is next. `edge-feather` and `edge-falloff`, not `feather` and `falloff`, because a radial mask already writes `feather` for the fraction of its radius it ramps over. Same word, different quantity, different units — sharing the key would have made an existing file ambiguous. The diagnostic that provoked this is committed as an ignored test, because "does the ladder land on things a person means" is the question S15 exists to answer and it should not depend on whoever still has the script. On bus.jpg it answers badly: 35,075 regions at blur 2 over an 810x1080 frame, and cutting that to 400 gives *one* region covering nearly the whole picture plus 399 noise specks. Not over-segmentation — collapse. Almost every saddle is near zero, so the merge order joins everything meaningful before it joins anything spurious, and a global cut spends its entire budget on grain. So the granularity ladder does not currently work on a photograph, and the region masks built on it inherit that. Recorded rather than worked around: the next commits move local masking onto the model's instances, where the edge treatment above is what makes a quarter-resolution mask usable. |

Record what the spec got wrong about the model that exists
docs/segmentation.md §4 priced arm B as costing a C dependency under the NDK and treated that as most of the difference between the arms. It is not a cost that has to be paid: `ort`'s `alternative-backend` disables its linking entirely and `ort-tract` supplies the API from tract, which is pure Rust. D13's "largest exception the policy would tolerate" turns out not to be needed, and the answer generalises to the face pipeline — so D13's runtime half is now answered and only its licensing half is open. Three findings contradict §4 outright and are recorded as F4-F6 rather than quietly designed around. There is no ADE20K-trained YOLO, so the shipped vocabulary selects subjects and not stuff — "select the sky" comes from the watershed or from nowhere. It is instance segmentation, so it partitions nothing and two people come back as two instances. And tract cannot parse a dynamic-shape export, which fixes the input at 640 square and makes tiling the only route to more semantic resolution. Arm C ships, but §8's criteria are not what decided it, and saying so matters more than claiming the process worked. §8 asked for a two- interaction margin over arm A on a traced corpus. That comparison was never run: F4 and F5 changed what the arms are, and a model that recognises subjects but has no word for sky cannot be a selection tool alone, while a watershed cannot tell a person from the wall behind them. They stopped being candidates and became complements. What is *not* done is written down as plainly: the 24-image corpus is untraced, so M1-M4 have no numbers and "this feels right" has not become one. M5 is answered on one device only, and region ids now reach the sidecar — so a cross-vendor divergence would mean a mask written on the desktop meaning something else on Android. F3 stands. |

Show the regions, click one, and adjust it
The local panel sits above the adjust panel because it decides what those sliders act on; below it, a photographer would set an exposure and only then discover which scope it landed in. Selecting a layer re-scopes the existing controls to that layer's chain — there is no second set of sliders, and there must not be, or every operation added to `ops/` would need a local twin. The overlay is drawn over the canvas rather than blended into the render, because it is a diagnostic and not an edit: it must not reach the histogram, an export, or the texture handed to the compositor. Nearest- neighbour always — the map's values are *names*, so smoothing between region 4 and region 9 invents a colour belonging to neither and softens exactly the edge the overlay exists to show. Picking gets its own touch area above the pan handler. Panning wants press-drag-release and picking wants a click; interleaving them in one handler is how a drag ends up selecting a region the user was scrolling past. Shift is tracked as window state because a TouchArea's click carries no modifiers. Three states a layer can be in are worth distinguishing, and each has a different remedy: stale needs re-segmenting, "no adjustment yet" needs a slider moved, and the ordinary case needs nothing said. A bare selection renders nothing and looks identical to a broken mask, which is the first thing a new user will hit. Known rough edge, commented where it happens: segmentation blocks the UI thread for about half a second. Moving it to a worker needs the develop session — GPU resources behind a RefCell shared with every callback — to be reachable from another thread, which is a restructuring rather than a change to the call. The button says "Finding regions…" first so the stall is announced rather than looking like a hang. |

Put the region map behind the sliders that were already there
A mask layer holds a real develop chain, so the develop panel can edit one with no new controls: select a layer and the same sliders read and write its chain instead of the graph's. An operation declared in `ops/` tomorrow becomes locally adjustable by existing, which is the payoff for making a layer a chain rather than a handful of special-cased parameters. `segmentation.rs` joins the two arms into the one thing the view needs. The model reads the image through a neutral graph rather than the edited one, so a segmentation survives an exposure change instead of being invalidated by every slider. Arm B failing is not fatal: a missing or unreadable model leaves a working watershed map, because refusing to segment at all would trade a working feature for a strict one. The overlay colours groups by a golden-angle walk over hue. Deterministic rather than random, so a region keeps its colour across a level change and the eye can track it; boundaries drawn black over the fill, because two adjacent groups landing on near hues read as one region and telling them apart is the whole reason to look at it. Clicking the photograph creates the layer if none is selected — that is how a local adjustment begins, and making the user press "add layer" first would be a step with no decision in it. Shift-click extends, and clicking a region already selected removes it, so one gesture both adds and corrects. `segment-readback` is a new dr-gpu feature and not a loosening of `readback`. The region-graph transfer is once per image on a worker; the one AC-8 forbids is per frame in the render loop. Sharing a switch would have forced a build wanting local masking to unlock the other. F3 still stands and the feature name says so. |

Keep the mask when the app closes, and when two devices disagree
The sidecar is authoritative — the catalog is a disposable index and the RAW is never written — so a mask that does not round-trip is not a persistence bug, it is lost work. Layers get their own `[mask <version> <id>]` blocks rather than being flattened into dotted keys. A layer is not a scalar: it carries a selection, a geometry and a chain of its own, and encoding a region set as `m1.region.0 = 12` would be neither readable nor mergeable. The version uuid is repeated in the header instead of relying on the block following its version, because "belongs to whichever version appeared above me" is a relationship that hand-editing, merging and older builds each break quietly. Region ids sort and deduplicate on read rather than being trusted from the file. The mask's identity is the *set*, so two devices writing the same selection in different orders must produce the same mask rather than argue about a difference that is not one. Masks merge by layer id under FR-NC-9, which is the disjoint-survives rule the parameters already follow one level up: a layer added on the phone and one added on the desktop both survive. A layer *both* sides edited resolves wholesale to the higher revision, because half of one selection plus half of another's opacity is a layer neither person made. A remote deletion is honoured, or a mask the user removed returns on every sync. An unknown mask source is skipped rather than guessed at. Applying a newer format's mask type as the nearest one this build knows would put a confidently wrong adjustment on the photograph, which is worse than applying none. 29 new tests. The interesting ones are about silence: a maskless version clearing the previous image's layers, a bare selection persisting even though it renders nothing, and a mask naming a version that is not in the file being dropped instead of landing on whichever block was open. |

Brighten her face without touching the sky behind her
A mask layer is an ordinary develop chain plus a rule about where it applies. Nothing in the chain knows it is being masked, so every operation that works globally now works locally and a newly declared op in `ops/` arrives with local support already done. The composer emits each layer after the global chain and before the conversion out of camera space, which is what a photographer means by "and *then* lift the shadows on her face". Op fragments write to a `c` they expect to own, so a layer block shadows it and copies the result back out through a carrier — assigning the outer one from inside is impossible precisely because it is shadowed. The fused dispatch survives: three global adjustments and two masked ones remain one shader, one read, one write. Masks rasterise on the GPU and never exist in CPU memory (ARCH §5.4). That is the whole reason darktable's brush masks lag, and it is architectural rather than tuning, so it is not a thing to inherit and fix later. The rasteriser is a render pass rather than the compute shader it obviously wants to be, and the format is why: R8Unorm is not a core storage format, so a compute path has to widen masks to four bytes per pixel — 768 MB across eight layers of a 24 MP export, against 192 MB at one byte. A colour attachment takes R8Unorm happily. The array slice comes from the attached view, so no slot uniform exists to disagree with where the pass writes. Region masks index a compacted label field rather than the watershed's raw basin roots, because a root is a sparse index into pixel space and indexing a per-region array by one would need a table the size of the image. Changing a selection then costs a few kilobytes, not a re-upload. Stored as region ids, not as pixels: diffable, mergeable per-field under FR-NC-9, and cheap in a sidecar. The ids only mean anything alongside the segmentation that produced them, so each layer carries that signature and is treated as stale rather than applied when it does not match — a confidently wrong mask being much worse than an absent one. Seven device tests render actual frames and read them back. The unit tests either side check halves that would both pass if the two agreed with each other and were both wrong; a mask sampled with x and y swapped satisfies them and fails these. |

Let the model say what a thing is and the watershed say where it ends
Local masking needs to know where an image's regions are. The watershed spike (S15 arm A) found the boundaries but had no idea what any of them enclosed; its coarse levels were geometric accidents. This adds the other half and the thing that joins them. `core/dr-segment` is where region reasoning now lives — the hierarchy moves out of `dr-gpu`, which keeps only the pixel passes that are genuinely shaders. The new crate is device-free and, without its default features, model-free too: 20 of its tests need neither an adapter nor 11 MB of weights. Arm B runs YOLO26n-seg through `ort`. D13 framed inference as a choice between `ort`'s C++ runtime and the pure-Rust dependency policy; that was a false choice. `ort`'s `alternative-backend` feature unlinks the C entirely and `ort-tract` supplies the API from tract, which is pure Rust. Measured before committing to it: zero unsupported operators, 420 ms for 640x640, and correct masks on bus.jpg. No NDK problem to solve, so D13's largest tolerated exception is not needed. Arm C is `prior.rs`, and it ships because the two arms fail in opposite directions. Instance membership re-weights the merge saddles, so region pairs the model believes share an object merge early and pairs straddling its edge merge late. No boundary moves — only the order in which they dissolve — which is how the result stays pixel-accurate at every level while its coarse levels become named things. Two things the spec assumed that turned out to be false, both recorded in models/LICENCE.md: there is no usable ADE20K-trained YOLO, so the shipped vocabulary is COCO's 80 subjects and *stuff* like sky and foliage must come from arm A; and tract cannot parse a dynamic-shape export, so the graph's input is fixed and tiling is the only route to more semantic resolution. Weights are AGPL-3.0, which GPLv3 §13 permits and which makes the combined work effectively AGPL. Deliberate, not accidental. They live in Git LFS, and a build script fails with an instruction rather than embedding a pointer file when the clone lacks them. |

First step of dead pixel removal, and the one that decides whether the rest is worth building: where the map comes from. `rawler` is no help. It knows `OpcodeList1/2/3` exist — it copies them through when *writing* a DNG — but it never decodes them, and the `dng_tags` map it exposes is only ever filled by callers, never by a decoder. So the bytes are read from the IFD directly, which this module was already walking for previews, including the SubIFDs where a DNG keeps its raw IFD. `OpcodeList1` specifically: lists 2 and 3 run after demosaic and after the colour transform, so neither can carry a correction that has to happen on the mosaic. Two opcodes describe defects — `FixBadPixelsList`, which is explicit coordinates plus whole dead rows and columns, and `FixBadPixelsConstant`, which names a sentinel value rather than any coordinates and is left unimplemented until there is a stage to consume it. A half-implementation that guessed at coordinates would be worse than the absence, because it would look like it worked. Two things the tests pin down because both are silent when wrong: a point is stored (row, column) and reading it the other way round lands the correction on the wrong photosite — invisibly, on a square crop — and opcode payloads are big-endian whatever the container's byte order is, so a little-endian TIFF still writes these the other way round. An unknown opcode is stepped over using its declared length rather than abandoning the list, because a camera that corrected its lens as well as its sensor writes both, and losing the map whenever a warp is present would be losing it on most files that have one. Includes `--example defects`, because whether any of this fires is a question about a particular library rather than about the specification. |

Re-thumbnail a photograph from its own edit
A thumbnail comes from the file's embedded preview, which is the camera's idea of the photograph and knows nothing about what has been done to it since. So a frame could be cropped, turned upright and pulled two stops back, and the grid would go on showing the original — making the library, where a photographer spends most of their time, the one view in which an edit is invisible. The render is the framed output, not the sensor: `output_size` is what a crop, a quarter turn, a flip and a straighten all act on, so a thumbnail taken from the raw frame would be the right pixels in the wrong shape and still the wrong way up. It is the same path an export takes, at a size the store wants rather than at full resolution, and always sRGB — this is a JPEG in a shard that syncs between devices and is drawn as a cell, not a file anyone is finishing. Both size classes are replaced. The store keys on the class, so refreshing only the one the grid happens to be drawing leaves the other holding the unedited preview, and a zoom across the boundary would show the edit undoing itself. Each is rendered rather than downscaled from the larger, which would be a second and worse resampler than the GPU has already applied. It runs on the way out of develop, after the sidecar write is queued and never instead of it — the edit is what must not be lost, and a render that failed must not take the save down with it. Two cases are worth the work: an edit made in this sitting, which `can-undo` records even when it ends back at neutral, and an image opened with an edit already in its sidecar and left untouched, whose cached thumbnail has never shown that edit at all. A neutral image nobody touched fails both and costs nothing. Not covered: a batch paste onto a selection, which deliberately never opens a session — there is no rendered frame to take a thumbnail from, and downloading forty RAWs to make forty is exactly what that path exists to avoid. |

Leave the stars on screen on a touch device
**Hover is not something a finger does, but Slint reports it anyway.** `has-hover` goes true for any pointer event carrying a position, a touch press included, and false again on the `Exit` that follows the release. So the rating strip did appear on a tablet — for exactly the length of a tap. It flashed on under the finger, vanished as it lifted, and the tap carried on through to the cell and opened the photograph. An unjudged frame could not be rated from the grid at all. The previous fix stopped the strip disappearing when a *pointer* moved onto it; this is the same symptom with a different cause, and hover was the wrong signal in the first place. The strip now stands open where the session is a touch one. That is seeded from the platform rather than inferred, because inference needs a press to reach a cell and a quick flick never delivers one — the Flickable claims the gesture before the delay it would forward after — and a control that only appears once the finger is down has appeared too late to aim at. The grid still latches on the first non-zero touch id it sees, which is what covers a touchscreen on the desktop. One-way on purpose: a tablet with a mouse plugged in keeps the strips once touched, which is the harmless direction to be wrong in. The alternative is chrome that comes and goes as the user changes hands. |

Make a pinch zoom the grid and nothing else
Two faults left over from making the gesture reach the grid at all. **It still opened photographs.** Checking the finger id stops the synthetic release Slint emits when the *second* finger lands, but not the other end of the gesture: lifting one finger of two leaves the other one down, and Slint replays that survivor as a fresh `Pressed` on whatever is under it — which is how it hands the pointer back to ordinary handling. Under it is a cell. So the cell was selected, and lifting that last finger was a complete, well-formed click on the same finger that pressed. No part of the event stream distinguishes it from a real tap, so the grid now remembers that a pinch just happened: a latch raised when the gesture starts and lowered a beat after it ends, during which cells take neither presses nor clicks. The press that *opens* a pinch is undone rather than suppressed — it has already happened by the time a second finger makes it a pinch. Undoing it has to be exact, or a cancel that restored the selection but left the anchor moved would make the next shift-click select a run from a cell nobody pointed at, so capture and restore are a tested pair. **And it was not smooth.** Two reasons. The pinch was thresholded into ±1 steps of 25%, so the grid lurched and then sat still; it now takes the ratio since the last update and tracks the fingers, with the drawn cell still landing on whole column counts because the columns divide the width. And `zoom-cells` was the one geometry change still reloading inline — a full catalog re-read, 360-row model rebuild and thumbnail batch per step, on the thread drawing the frame. It goes through the same settle timer as the rest now. |

Swipe up in develop for the photo roll
Develop opens one photograph. The grid handed over a path and nothing else, so `index` and `total` were pinned to "1 of 1" on the way in and the only route to the next frame was back to the library, find your place, tap again. Fine once; intolerable through a set of forty, which is the situation the develop view exists for. The roll is the grid's already-loaded window along the foot of the canvas. Swipe up to bring it out, swipe down to put it away — the sheet gesture, already in the hands of anyone who has used a phone — and a handle is drawn at the edge so the gesture is discoverable rather than folklore, and so a pointer, which has no swipe to make, has a way in. `SwipeGestureHandler` wraps the strip rather than sitting over or under it, which is what it is built for: it delays a press the way a Flickable does, forwards it to the children if no swipe develops and claims it once one does, so a tap reaches the thumbnail and a drag does not. It covers only the band along the bottom — above that, a drag still belongs to the photograph, for panning and for the crop. Picking goes through the same path a cell click does, so the outgoing edit is persisted before the next image loads. The strip marks what is open and scrolls to keep the mark in view. The position readout now says where in the *library* the open photograph sits rather than "1 of 1". Set after the open rather than before, since the generic open path resets it — and given as the library ordinal, not the row in the loaded window, which is an artefact of how much has been paged in and would jump about as the window moves. |

Stop a row of buttons deciding how wide the grid is
**A Slint layout cannot be narrower than its children's minimums.** Given less room than they need it lays them out at those minimums, lets the row run past the edge — and reports the oversized minimum upwards. That second half is what made this more than cosmetic. The header, the filter chips and the grid are siblings in one VerticalLayout, so the widest row's minimum became the whole view's minimum: `LibraryGrid` was laid out wider than the window. The grid then measured itself against that inflated box and sized its columns to fill space that was off the screen, so the right-hand column was cut by the edge no matter what the tiling arithmetic did. Fourteen filter chips do not fit across 768 logical pixels, so that was every tablet in portrait. It also explains why opening the collections sidebar did not reflow the grid. The view was already pinned at a minimum wider than the window, so taking 232px away for the sidebar could not shrink it — it just clipped more of it. Each of those rows is now a horizontal Flickable. A Flickable's own minimum is nothing, since it exists to be smaller than what it holds, so none of them can inflate anything — and the controls past the edge became reachable instead of merely absent. Applied to all four: the library header, the filter chips, the compact action row disclosed by "More", and the develop strip. |

Stop zooming rebuilding the grid twice a frame
A pinch is not one zoom step, it is a stream of them, and every step changes both the column count and the capacity — two reports. Each report re-queried the catalog, rebuilt all 360 rows of the model, re-read the badges and ratings for every one of them and spawned a thumbnail batch, synchronously, on the thread trying to draw the frame. Twice per step. That is why zooming juddered while scrolling the same grid is smooth: a scroll reloads a few times per screenful, a zoom reloaded twice a frame. None of that work is urgent, because none of it is about which photographs are on screen. The window holds the same images however they are laid out — the model already has them, and the cells re-flow from `columns` and `cell-size` with Rust not involved at all. What the reload actually recomputes is which cells begin a row, so the month headings land correctly, and which thumbnail size class to ask for now. Both can wait for the gesture to finish, so both are now coalesced behind a single settle timer: replacing the timer drops the previous one, and only the last report of a run lives long enough to fire. The anchor is captured on the first report of a run rather than read when the timer fires. As the grid re-flows the viewport keeps its pixel offset while the rows move underneath it, so the view drifts and reports the drift; reading the anchor at the end would faithfully return to wherever it had wandered. Taking it at the start returns to the photograph the user was looking at when they started the gesture. |

Tile the thumbnails to fill the width
The cells were drawn at whatever pixel size the class asked for and the remainder was left as a bare strip down the right-hand side — up to one short of a full column of nothing, which on a phone is a quarter of the screen. It also had the two quantities depending on each other the wrong way round. The column count was derived from the fixed cell size, so the two could disagree about how much room there was and the last column could start inside the viewport and end outside it. Solving for the cell removes both at once. Pick how many columns of roughly the requested size fit — rounded, not floored, because the size class is a request rather than a measurement and a width nine tenths of the way to another column should take it — then make those columns share the width. `columns` cells and the `columns + 1` gaps around them come to exactly the grid's width, so there is no remainder to strand and nothing can overhang. The size class still decides what the user gets, since it is what the column count is chosen from. It just no longer dictates the pixel, so the cell flexes a few percent either way to make the row come out even. |

Give the develop strip room for its controls on a tablet
The render backend, the layout class and the frame rate are developer readouts, and they were sitting in the middle of the one strip that also carries the way out of develop, the undo pair, the panel toggle and export. A HorizontalLayout given less width than its children's minimums does not shrink them — it runs off the end. A tablet in portrait is 768 logical pixels, which is not enough, so everything from the panel toggle rightwards was pushed off the right-hand edge. Below the breakpoint the develop column is *also* closed by default, so a toggle that could not be reached meant the column could not be opened at all — and copy and paste live in that column. That is the whole of "I have no idea how to copy a setting on Android and apply it to other images": there was no way to. The three readouts now collapse to zero width below the breakpoint. Width and not an `if`, because this strip is inside the layout that `expanded` feeds and a conditional child here is the shape that has already caused binding loops in this file — and because a `visible: false` child still takes its slot in a layout, so hiding alone would have freed nothing. |

Show the library on launch instead of scanning first
A launch does not have to discover the library. The catalog from the last run is on disk, complete, with its thumbnails in the shards beside it — exactly the state offline mode already leans on when the server cannot be reached. Every launch that *could* reach the server threw that away. The catalog handle was only opened when the scan reported Done, so the grid sat on "Scanning…" over an empty EmptyState for as long as a recursive WebDAV walk of the whole tree takes. On a real library that walk is essentially the whole startup time, and it was spent hiding a grid that was ready before it began. The catalog is now opened and the first window loaded before the scan thread is spawned — before, so the schema migration cannot race the worker opening the same file, and so the first thumbnail batch is already in flight while the walk runs. The scan still replaces all of it the moment it lands; it just no longer gates the first paint on the network. A first run has nothing to open, which stays silent: `Catalog::open` creates the file, the grid reads an empty catalog, and the empty state goes on saying "Scanning…" — which is true, and which an error here would contradict. |

Keep the view pointing at the same photograph when the columns change
Two faults behind "the gallery randomly glitches to blank and needs a scroll to reset it", and behind the scrolling that skips. Cells are drawn at their absolute place in the library, so the row a photograph sits on is `index / columns`. When `columns` changes every cell moves — and the Flickable's `viewport-y` did not move with them. The view was left pointing at a row that now holds entirely different photographs, typically thousands of images from the ones the loaded window covers, so the grid drew nothing at all. It stayed that way until a scroll reported a first-visible row and dragged the window back under the view, which is exactly the reset the user found. None of its triggers are rare: a resize, the collections sidebar opening, a zoom step, or turning the tablet over. The last first-visible ordinal names the photograph being looked at, so it is now sent back through `scroll-to` and the view lands on that same photograph at whatever row it now occupies. The second fault is the window-move test. At either end of a scope the window is pinned — the first screenful cannot be centred further back than zero, the last cannot start past the last full screenful — so the margin test was unsatisfiable there and every row crossed in the first or last quarter of a window re-read the catalog, rebuilt the model and issued a thumbnail batch to arrive at the offset it already held. On a library of twenty-odd thousand that is a stutter at the top and the bottom of every collection, which is where a cull begins and ends. The decision is now a rule with tests rather than four lines inside the scroll handler: both of its ways of being wrong are invisible in the code and obvious on a tablet. |

Carry a photograph's thumbnail across a reload
Work in progress found uncommitted in the tree, committed as its own change so the fixes that follow can be read separately. Not authored in this session; the description below is written from the diff. `load_window` rebuilds every row, and a scroll reloads once the view has travelled a quarter of the loaded window — so three quarters of the cells being rebuilt are the same photographs already on screen. Rebuilding them empty blanked the grid to `Theme.ground` and refilled it a beat later, once a worker had re-read and re-decoded each one from the store. That is the black flash on every screenful of scrolling, and on a column change, a zoom step, a filter and a return from develop. Thumbnails are now held by `image_id` across the swap — a refcount per cell, no pixels move — along with the "no preview" verdict, which is an answer about the file worth keeping for the same reason. `requested` is rebuilt from what the new model actually holds rather than cleared, so a carried cell is not fetched again while one newly scrolled in still is. The size class each cell's pixels came from is tracked alongside, so a grid zoomed past that class still asks for the sharper one. Also guards the whole `scrolled` and `columns-changed` handlers on `show-library` rather than just the resume latch: a Flickable being torn down passes its viewport through zero, which was indistinguishable from a fling to the top and reloaded the window against the first rows of the catalog every time an image was opened. |

Let the grid be pinched instead of opening an image
Two separate faults, both only reachable with a second finger. The gesture never arrived. `ScaleRotateGestureHandler` was sized `100%` inside the Flickable, which is the Flickable's own height, not its viewport's — so the handler was one screenful tall at the top of a viewport thousands of rows long. A pinch is delivered to whatever lies under the midpoint of the two fingers, so it landed on the handler only while the grid was scrolled to the very top and found nothing anywhere else. Sized to `viewport-height` now, exactly as `zoom-catcher` above it already is. And the attempt opened a photograph. When a second finger lands Slint closes the first one's gesture by synthesising a `Released` at its position — that is how a Flickable is persuaded to let go of a scroll it has already claimed. A TouchArea cannot tell that release from a real one and fires `clicked`, so every pinch opened whichever image the first finger was resting on. The finger id separates them: the synthetic release carries the id of the finger that *arrived*, never the one that pressed. `clicked` fires before the pointer event that names the finger, so it now only raises a flag and the `up` handler decides. A mouse reports 0 for both, leaving the desktop path exactly as it was. |

Keep the stars on screen long enough to click one
The rating strip was a sibling of the cell's TouchArea, declared after it so that hit-testing reached the stars first. That half worked: a star click set a rating without also opening the image. The other half did not. Hover is tracked per TouchArea, and Slint sends `Exit` to any item that drops out of the hit path. The strip taking the pointer is exactly that — `cell-touch` left the path, `has-hover` went false, and `show-empty` went with it. On an unrated cell the stars are drawn *only* on hover, so they vanished as the pointer arrived at them; the click then landed on the cell behind and opened the image. Reported as "the star menu disappears when I click on an image", which is precisely what it does. Nesting the strip inside `cell-touch` keeps both halves. Children are hit-tested before the element containing them, so a star still wins the click and still ends the walk before `cell-clicked` runs. And an ancestor stays on the item stack: it gets no `Exit`, and while a child holds the grab it is handed the event filter and never the event. Hover therefore holds for as long as the pointer is anywhere in the cell. |

Measure the grid against the grid, not the whole view
`cell-size`, `columns` and `visible-rows` were all derived from the LibraryGrid's own width and height. The cells are not drawn in that box: the capture-time axis is a sibling of the grid, 96px of it, and the header takes another 44px off the top. So `columns` counted the timeline as room for thumbnails and fitted one more column than there was space for. The last column started inside the Flickable and ended outside it — clipped, with no sideways scroll to reach it. At the 180px size class on a phone in portrait the timeline is a quarter of the screen, which is most of a column. `visible-rows` was wrong the same way and fed `capacity`, so every window over-fetched by the ratio of the header to the viewport. Both now read `grid-area`, the layout the cells actually live in. That is a descendant, and reading a descendant's geometry is the shape that causes binding loops elsewhere in this UI — but not here: nothing derived from these feeds back into the layout. The cells are placed absolutely inside the Flickable and a Flickable's layout constraints are a bare `stretch: 1` that its viewport cannot influence. |

Give the app a face and a name on the launcher
There was no icon anywhere, and on Android that was not a missing line in the manifest. `aapt2 link` was being handed a manifest and nothing else, so the APK carried no res/ and no resources.arsc — there was no table for an `@mipmap/...` reference to resolve against even if one had been written. Packaging now compiles the resource tree first and links the result in, which is the two steps aapt2 insists on: link reads compiled input only, never a directory. That absent table is also why the launcher caption was blank, which had looked like a second, separate bug. `android:label="DarkRoom"` was there and correct the whole time, and Settings' App info read it fine; the launcher could not, because resolving a label goes through the package's Resources and there were none to open. Nothing about the label changed here. It came back with the table under it. `android:icon` then names one drawable for both icon generations, because the `anydpi-v26` qualifier is what separates them. API 26 and up take the adaptive icon and its three layers; the third of those, monochrome, is what lets Android 13 recolour it rather than drop the app out of the themed set. Below 26 the same name lands on a density-matched PNG. `roundIcon` is deliberately absent — a launcher old enough to read it is one that would ignore the adaptive XML, and minSdk is 28. The desktop icon is one `@image-url` on the window, and the only raster asset in a UI that is otherwise entirely Path. The reasoning at the top of icons.slint does not reach it: that is about glyphs a font might not carry, and this image is never drawn by us at all. It goes to the window manager, which wants pixels and composites them unmasked, so it is pre-shaped with rounded corners rather than square the way the Android layers are. Which exposed Slint's resource default. An `@image-url` compiles down to the absolute path it had on the build machine, to be opened at runtime — already wrong for Android, where the build happens under /work inside a container and no such directory exists on the device, and wrong silently, as an image that loads empty. `EmbedFiles` puts the bytes in the binary instead. It reaches nothing else, since every glyph is a Path. Verified on a device: the APK installs and the home screen draws both the icon and "DarkRoom" under it, where before it had neither. In the link step the adaptive icon resolves at all six densities and resources.arsc lands uncompressed, which API 30 requires and the existing zipalign preserves. On the desktop by reading _NET_WM_ICON off the running window — 256x256, as handed over. Where that actually shows is narrower than it sounds, and the comment says so: Wayland ignores the property in favour of matching app_id against an installed .desktop file, which this repo does not install.

The colour mixer emits a code block and a uniform only for the bands that are set, so which bands are adjusted is part of the shader's structure. The pipeline cache key was not: it hashed the set of *active operations*, which is "colour_mixer" whichever band that is. So a red adjustment and a blue one hashed alike. The second render was handed the first's compiled pipeline while its uniform was uploaded into a slot that shader had assigned to another band — whichever band compiled first kept acting on every subsequent move, and every other slider did nothing at all. Red is the first band declared, and the one reported as the only one working. The hash is now taken over the generated WGSL, because the source is what gets compiled and therefore is the structure. A summary of what went into it has to be kept in step with every operation's code generation by hand, and this one had fallen out of step. Values still do not enter it: no operation writes a parameter value into its source, so a slider drag regenerates identical text and reuses the pipeline, and one that did inline a value would have to recompile to be correct anyway. `each_colour_band_gets_its_own_pipeline` in dr-gpu renders a blue pixel through one pass with red set first and then blue, and fails on the old hash with the reported symptom — the blue slider returning the pixel unchanged to the byte.

Straighten a portrait frame in the frame the user is looking at
The framing prologue built the centred position `p` by scaling with the source's aspect, then straightened, then permuted the quarter turns. On a landscape frame those are one space and it worked. Once a turn has swapped the axes — the rotate button, or a file whose EXIF tag says the camera was held sideways — they are not: `p` was measured with the source's ruler on a frame that is no longer that shape, stretching one axis against the other by (w/h)², which is 2.25 on a 3:2 photograph. The quarter-turn permutation happened to undo that stretch, so rotation alone looked right, which is how this survived. The straighten in between did not, and a rotation in a space whose axes carry different scales is a shear. `p` is now built in `frame_aspect` — the frame as the user sees it — and the permutation becomes the one place the two rulers meet: each axis divided by the aspect it is read from, multiplied by the aspect it is written to. Asserted on pixels rather than on the generated WGSL, because reading the shader and reasoning about which space `p` lives in is how the wrong formula got written in the first place: a disc, straightened by 20° on a turned 3:2 frame, must come back circular by every route to a swapped frame — the button, the tag, and the two composed.

The gesture is Slint's and cannot be driven from a test — synthetic drags do not reach a DragArea at all — but the decision it leads to is where this can actually go wrong, and it was buried in a callback. `decide_drop` names the three outcomes and the order that separates them: an image drag always fills the payload, so photographs pressed after a row was clicked are still filed rather than read as a rearrangement. A row dropped on itself is a no-op here rather than a cycle error from the catalog, and an empty drag with nothing remembered — a file from another application — leaves the tree alone.

Drag a collection onto another to nest it
The tree could be built nested but never rearranged: `set_parent` existed, with its cycle check and its tests, and nothing in the UI called it. A collection created in the wrong place stayed there. Each row is already a drop target, so it becomes a `DragArea` too — wrapped at the instantiation site the way the grid's cells are, which keeps the row's own TouchArea nested underneath and a click still selecting. `allow-move`, not copy: a collection has one parent, unlike a photograph, which is filed in as many collections as you like. The drop is handed only the target's id, so the source is remembered from the press that precedes the drag — Slint builds the payload through a `pure` binding, which must not have side effects. An image drag always fills `dragging`, so an empty payload with a remembered row is unambiguously a rearrangement; the row is taken rather than read, or a later empty drop would move a collection nobody touched.

The library could be narrowed by rating, flag and availability, but not by when a photograph was taken — so finding a fortnight meant scrolling to it and holding position. The range rides on `RatingFilter` for the reason `local_only` already does: every query path threads that one struct, so the count in the header cannot claim a total the grid does not draw. Undated images are excluded whenever either end is set — they cannot be inside or outside a span, and drawing them made the range look as though it had not applied. Taken from the timeline rather than typed into two date fields. Finding the period is what the histogram is for, and having found it the user should not have to read the dates off the axis and key them back in. The histogram keeps drawing the full extent while the range is on, or there would be nowhere to widen back out from. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

Keep the selection visible when the grid scrolls under it
Scrolling rebuilds every cell, and a fresh cell carries `selected: false`. `sync_badges` and `sync_ratings` refilled what the rebuild cleared; nothing refilled the selection, so the ticks vanished on every scroll. The selection itself was never lost — it is a set of image ids and survives untouched — which made this worse than losing it: the header buttons still acted on forty photographs the user could no longer see were held. `load_window` reaches the selection through a `Weak` handle set at wiring. Weak because the two controllers are joined only through the window, and an `Rc` each way would leak both; absent, the grid draws nothing selected, which is what it did before.

The timeline counted the whole library whatever the grid was showing, so opening a collection left a fortnight in Arosa as one column of a fifteen-year axis — an axis describing photographs that were not on screen. Scope the buckets and the span to the same collection and rating filter the grid uses. `timeline_range` counts `images` alone and cannot express the membership join, so the scoped query lives beside the other scoped readers in the UI and shares their descendants-of-scope rule. `catalog_span` now delegates to the same scoped reader. Zoom and scrub measured the full library while the bars were scoped, so a scrub could land on an instant the collection did not contain and send the view somewhere the user had not asked to go.

The merge inserted every incoming collection with `parent_id = NULL` and never set it on update, so the hierarchy flattened on each round trip: a collection nested on one device came back from the server at the top level. `r.parent_id` was selected and then not read. The id could not be copied — row ids are local, and the remote's integer names a different collection here, or none. So carry the parent's uuid and resolve it locally, in a second pass: rows arrive in whatever order the query returns, and a child can precede its parent. Guard the resolution against cycles. Each tree is acyclic alone, but the union need not be — we may hold A above B while the remote holds B above A — and closing that loop would make every tree walk spin.

Look before overwriting the file we are asking about
The probe PUT its bytes first and read the outcome, which answers the question by destroying the evidence: pointed at a real sidecar it would replace an edit with the word "probe", and on success delete it outright. PROPFIND first. Permissions and status usually settle create-versus-update on their own, and a path that already exists is now reported and left alone. `--write` still forces the update test for a file worth losing, and the cleanup DELETE fires only for a path the probe itself created.

Ask the file, not its folder, why the write was refused
The 403 probe read `oc:permissions` off the parent collection and warned when `W` was missing. But Nextcloud reports `W` on files and `CK` on collections, so a directory legitimately lacks `W`: the warning fired on a healthy share and pointed at a mount that was fine. Probe the file itself. Its permissions answer the question that matters, and the status distinguishes the two cases the parent could not: a 404 means the sidecar does not exist and the refusal was about creating it, while a 200 without `W` means it exists and cannot be updated.

Diagnose the refused sidecar: the library mount is create-only
Ratings and edits made on the tablet queue and are then refused on reconnect,
on a credential that pushes the catalog to the same library root in the same
sync pass. Chased on the device, since that is where the account lives.
A failed PUT now logs the server's own words, and on a 403 asks the parent
what rights it reports. The answer:
PUT .../PhotosRaw/2026/2026-08-03/_MG_9221.drsc -> 403
<s:exception>Sabre\DAV\Exception\Forbidden</s:exception>
parent permissions: MGNVCK
`M` mounted, `G` readable, `N` renameable, `V` moveable, `CK` create files and
folders. Absent: `W`, update an existing file, and `D`, delete. So `PhotosRaw`
is a mounted share that accepts a file once and refuses every change to it
afterwards.
That is the whole bug, and it is not one this side can retry its way out of. A
sidecar is rewritten on every rating and every edit, so the first judgement on
a photograph is written and every later one is refused — which reads as sync
being broken rather than as a share missing one permission. **The fix is to
grant update, and ideally delete, on that mount.**
`PermissionDenied` now says so, rather than "not allowed to write here", which
sent the reader to re-check a login that was working. Its test asserts the
intent — points at the folder, never at the credential — rather than a
phrase, so saying it better cannot read as a regression.
Also adds a `put_probe` example that makes the same request from a stored
session, for diagnosing this from a desktop when one is signed in.

Log why the server refused a write, in its own words
A queued sidecar fails to upload with 403 on a credential that pushes the catalog to the same library root in the same pass. `map_status` reduces every non-success to a typed error, which is right for the application and leaves nothing to work from: a read-only share, a file access control rule and a lock all arrive as `PermissionDenied`. Sabre says which in the response body. It is now logged on any failed PUT — the URL, the status, and the first line naming the exception or message, capped at 300 characters because an error page can be a whole document. Only on failure; a success has no body worth reading. Also adds a `put_probe` example that makes the same request from a stored session and prints the reason, for diagnosing this from a desktop rather than from a tablet's logcat. It needs a session on the machine it runs on, which is why the log line above exists as well. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

Name the sidecar the drain could not deliver
The write path learned to say which file the server refused; the drain path —
the one that runs for work queued while offline — still reported only a count.
That is the path that matters most, because everything it carries was made
with no connection and exists on one device.
With it named, the failure on the tablet is:
draining PhotosRaw/2026/2026-08-03/_MG_9221.drsc:
permission denied
on a credential that pushes the catalog to the same library root in the same
pass. So this is not the account and not the app password: one path is
writable and another is not, which points at the server — a read-only share
over that folder, or a file access control rule on the extension — rather than
at anything this side can retry its way out of.

Say which sidecar the server refused, and where
A queued sidecar failing to upload was reported as a count and a reason — "1 queued sidecar(s) still undelivered: permission denied" — with the path only at debug level, which the app filters out by default. That is unsynced user work: a rating or an edit that exists on one device and nowhere else. Which photograph it belongs to, and which path the server refused, is the whole of what makes the failure actionable, and without it a 403 on a single file reads the same as a whole library failing to sync. Observed on the tablet, where writes to the derived folder succeed on the same credential — the catalog pushes fine — while one sidecar beside its image is refused. That combination says the path matters and the account does not, so the path is the thing worth printing. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

Render a blown highlight white instead of magenta
Every clipped sky came out bright pink. Measured, not guessed: developing _MG_8596.CR2 and looking at the export, the subject renders correctly and only the saturated region is wrong. A fully clipped pixel reaches the shader as (1, 1, 1) — three photosites that stopped counting, carrying no colour at all. The as-shot multipliers are not neutral, so balancing sends it to (1.93, 1.00, 1.68) on this body, and the camera matrix turns that into R 2.88, G 0.51, B 2.03. Red and blue clip at one; green, whose matrix row is far less positive-heavy, does not. Red and blue high with green low is magenta. Nothing upstream was at fault, which is why the two previous attempts missed it: the white balance is correct, the matrix is correct, and the sensor normalisation is correct. The input simply was not a colour, and correct arithmetic on a non-colour produces a confident wrong answer. So saturation is detected before the balance is applied — the last 1.5% of range, smoothstepped rather than switched, because a hard threshold draws a visible rim around every highlight and a backlit edge on skin is where that shows. Above it the pixel is pulled to the neutral of its own brightness, so it keeps its luminance and loses only the cast. Verified end to end on the file itself: the sky is white, the skin, the black dresses and the stone are unchanged. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

Read the true white level, and clamp the sensor stage at both ends
Two corrections to the sensor stage, found while chasing magenta highlights. Neither is the cause of that — see below — but both are wrong on their own terms. `white_level` took the *first* of rawler's per-channel saturation points. On a Canon 6D that reports 15070 while the data reaches 16383, so every sample above it was treated as brighter than white. It takes the maximum now. The normalisation clamped its floor and not its ceiling, so those over-white samples passed through as values above 1.0. Clamped at both ends. **This does not fix the pink.** Measured on _MG_8596.CR2, exported and looked at: the subject renders correctly and only the blown sky is magenta. A fully clipped pixel is (1,1,1) in raw, the as-shot balance multiplies it to (1.93, 1.00, 1.68), and the camera matrix turns that into R 2.88, G 0.51, B 2.03 — red and blue clip at one, green does not, and the result is magenta. It is correct white balance applied to already-saturated data, which is the classic highlight-clipping cast and needs highlight desaturation to fix: a pixel at saturation carries no colour information and must be rendered neutral, not balanced.
