dtourolle	2d878c2117	Offer the film stock in its own group, and let its list scroll itself ... Two faults in one control, both reported from the tablet. The stock picker appeared in every group. It is not a parameter, so it is not a row, so the filter that hides every other control when a group is chosen never saw it — "Kodachrome" sat at the top of Light, of Colour and of Detail alike. Three places it does not belong, and the one it does no more prominent than the rest. The descriptor has said `Effect` and only `Effect` since the film moved there; nothing was asking it. So the panel now asks. It cannot ask directly — a generated panel may not know which operation a control belongs to — so the session answers, from what the operation declares it is about, and a stock re-declared as something else would move on its own. The flag is recomputed when the group changes as well as when the film does, which is the half that would have made it stale exactly when it mattered. And the open list was unbounded, so it made the develop column taller and the column scrolled as one: reaching Velvia dragged every slider below it off the screen, an answer given once pushing aside the controls used constantly. It now scrolls within a bounded height of its own. That viewport is counted rather than measured, for the reason the tool rail records a few files away: a viewport that asks a layout how tall it wants to be, while the layout takes its height from the viewport, is a cycle Slint settles by handing back the height it was given — and the content is then clipped in silence rather than scrolling. Every row here is one fixed height, so multiplying is exact. The group rule has a test. The scrolling does not, and cannot: it is a layout, and a layout fault is invisible to the compiler and to every assertion that can be written about it.	2026-09-07 20:42:15 +02:00
dtourolle	4c217c9be6	Show what a control does to a photograph, one parameter at a time ... A node that has just been declared can be read, reasoned about and tested, and none of that answers the question a photographer asks first: what does moving this do to the picture. Colour grading, dehaze and the range masks were all argued into the tree on their behaviour and none of them had been *looked* at. So two diagnostics. `sweep` walks one operation from its minimum to its maximum and writes a frame per step; `rangesweep` does the same for a mask band, which is not an ordinary parameter — it lives on a layer, is rasterised by its own pass, and only becomes visible through whatever adjustment the layer carries, so it gets two stops down to make the selection legible. `sweep` names no operation. The id arrives as a string and the parameters and their ranges come from the graph's own capabilities, so a node declared yesterday sweeps on the same terms as one that shipped a year ago — the property `ops/README.md` promises, used rather than asserted. Three things it learned the hard way and now records. It renders through `render_detailed` unconditionally, because the fused path refuses a shader composed with a detail stage rather than rendering it wrongly, and that call falls through when there is no such stage. It takes `SWEEP_HOLD`, because a parameter grouped under one widget is not meaningful alone: a hue with no strength behind it renders the same frame every time, which reads as a broken node rather than a correctly declared neutral. And it bounds the output, since a 25 MP frame is a 75 MB PPM and a sweep is hundreds of them. Both read a rendered file as readily as a raw one, so a JPEG can stand in where no raw is to hand — on the terms `from_rgba8` documents, with the controls still working and their neutral being what the camera left rather than what the sensor recorded.	2026-09-07 20:01:08 +02:00

dtourolle	0a5eab0487	Wire the develop panels through globals, so a second copy is one line ... Every panel in the develop column declared its inputs and its callbacks and had `app.slint` bind each one to a property or a callback on the window root. That is fine while a panel is drawn once. N9 draws them a second time, in the portrait dock, and the wiring is what would have to be copied: `MaskPanel` alone ran to forty lines of forwarding, and a callback added to one copy and not the other compiles, renders, and simply does nothing on the layout nobody was looking at. So the wiring moved to Slint globals. A panel reads the global and calls the global; Rust hooks the global instead of the window; and the instantiation in the column is now the panel's name and a pair of braces — every one of the ten children of the column, with no property that differs by placement left to supply. There is a global per panel family rather than one for all of them, and the reason is an import cycle. Each panel's model struct — `ParamRow`, `MaskRow`, `HistogramView` — is declared in the panel's own file, so a single global holding `[MaskRow]` and `[ParamRow]` would have to live in a file importing `masks.slint` and `adjust.slint` while both imported the global back, which Slint rejects. Breaking that needs six model declarations relocated, which is a change to the data model and not to the plumbing this is about. A global beside the panel it serves also lets each name drop the prefix it was carrying only because the window root is one flat namespace: `root.spot-radius` is `Repair.radius`, and `root.peaking-on` is `Peaking.showing`. `session.slint` is new and holds the two facts every family needs and none of them owns: whether there is an open photograph to edit, and which mode the view is in, with the three readings of the mode derived once instead of at each of the dozen places that tested one. `ViewMode` moves there from `adjust.slint`, where it was only ever a lodger. Nothing on screen changes. What is not here: the tool rail and the status strip still take their properties at the instantiation, because they are drawn once and N9 does not copy them; the preset sheet's own state stays on the window, because the library grid opens the same sheet and a global cannot bind the window's state — which is why `Transfer.open-presets` is handled in `presets.rs`, beside the summary it already had to compute.	2026-09-07 20:01:01 +02:00
dtourolle	dd14243dba	Lay the develop view out by coordinate, so the column can sit below ... Slint cannot turn a layout on its side, and that is what D-N7 asks for. So the HorizontalLayout holding the rail, the canvas and the develop column becomes a plain Rectangle and each of the three states its own x, y, width and height. With `column-below` false those come out where the layout put them to the pixel — a HorizontalLayout has no spacing or padding of its own, the rail and the column took their declared widths at the two edges, and the canvas was the only child that stretched. The alternative was the column subtree declared twice under two `if`s, which is four hundred lines of bindings copied, in a file whose own notes record a conditional child in a layout as the shape that has produced binding loops here before. The column is the same column either way: the same contents, the same Flickable, the same toggle. `panel-visible` collapses the dock's height exactly as it collapsed the column's width, so `column-width` and `dock-height` are each zero unless the column is both open and on that axis, and the canvas can subtract both without asking which case it is in. The stack inside stretches to the dock's width on its own — a layout that is the direct child of a Rectangle fills it, and the Flickable's viewport was already bound to its own width. Nothing is reflowed; N9 does that. `dock-height` is mandated in style.yaml for the reason `panel-width` beside it is, on the other axis: a dock that sizes itself to its contents is a photograph that changes height when a caption wraps. 480 until N6 measures the device. The seam follows the column round: a hairline down its left edge beside the photograph, along its top edge under it, so it stays between the two.	2026-09-07 20:00:50 +02:00
dtourolle	5f0b11c1f4	Ask the window how tall it is, and say when the column belongs below ... D-N7 puts the develop column under the photograph on a tall window, and the axis it turns on is aspect rather than width: a 960-wide portrait tablet is expanded by width and wants the dock, a 1500-wide landscape desktop is expanded by width and does not. So this cannot be folded into the layout class, and it is not remembered per class either — closing the column in landscape closes the dock in portrait, because it is the same column. `window-resized` reported width alone and now reports both, from a `shell-height` that subtracts the safe-area insets exactly as `shell-width` subtracts them: on Android the strips the status and navigation bars occupy are on the axis being measured, so the aspect of the window and the aspect of the space the interface actually gets are not the same number. `column_below` is the decision, with two thresholds rather than one. It is read on every resize event, and a single threshold means a window dragged along its own diagonal crosses it several times a second while the pointer is still down. Entering at 1.25 and leaving at 1.15 is a dead band no plausible drag re-crosses. The comment on EXPANDED_MIN_WIDTH claimed a tablet in portrait gets the compact layout. It does not — its panel is about 960 logical pixels across, which clears 820 — and that mistaken example is the one D-N2 reasoned from. Corrected in the same breath, since this is the commit that says what portrait actually changes.	2026-09-07 20:00:50 +02:00
dtourolle	30468c4c69	Put the window-metrics doc on the function it describes ... The comment explaining why both coordinate systems go on one line was written for `log_window_metrics` and sat above `window_metrics_level`, where it read as the start of that function's much longer note. Two doc blocks ran into each other and the one that prints had none.	2026-09-07 20:00:50 +02:00
dtourolle	428d8c4a51	Say what size the window actually is, in both coordinate systems ... Every figure in D-N7's table was computed at a guessed scale factor. The tablet's panel is 3000 by 1920 physical and nothing in this repository has ever recorded the density Android reports for it, so the dock's width is either 900 or 1037 and its available height is 200px either way. N6 asks for the measurement; this is the line that carries it. Beside the existing `apply_layout_class` call, because that is where the window is already being asked for its size and its scale, and again on every resize, so turning the tablet over records the other orientation in the same logcat. Both coordinate systems on one line: a logical size cannot be checked when the scale is the thing in doubt, and a physical size that does not divide by the scale printed next to it says the reading is of something other than the panel. The level is not fixed, because none of the three obvious choices works. `android_main` caps the facade at info, so debug never leaves the device and a debug-only line answers nothing. A drag emits a resize per frame and each accepted record is also appended to the on-disk log, so info on every resize is not a diagnostic. And the first reading is not the settled one: on X11 the window reports 0x0, then 360x320 at scale 1.0, then 1100x720 at scale 2.0, so reporting only the first would put a number in logcat that is not the window's. So the pair that decides is the scale factor and the orientation -- exactly what N6 is asking for, and exactly what a drag leaves alone. A window with no area is not a reading and records nothing. Every later change to either half, the scale resolving or the tablet turning over, is a new answer and goes out at info; everything else is debug.	2026-09-07 20:00:49 +02:00
dtourolle	2361b2d4ef	Tablet portrait is the expanded layout class, not the compact one ... FR-UI-1's table has put tablet portrait in the compact class since the register was written. D-N2 settled that it does not belong there: a 12-inch tablet is about 1024 logical pixels across in portrait and EXPANDED_MIN_WIDTH is 820, so both orientations of both targets are expanded, and compact fires only on a desktop window dragged narrow. The code has always agreed - apply_layout_class reads the window's width and nothing else - so the register was the last place still saying otherwise. What portrait actually needed was a different axis. D-N7 docks the develop column under the photograph on a tall window, set from the window's aspect and independent of the layout class: a 960-wide portrait window is expanded and wants the dock, a 1500-wide landscape one is expanded and does not. That is a placement rather than a mode, so the clause about the transition being continuous stands as written, and the requirement now records the side the column takes as its own property. FR-UI-2 gains one clause for the same reason. It said modality affects control sizing and affordances "not layout", which D-N6 reversed: under touch the group selector leaves the strip above the column for the tool rail, and groups-in-rail in toolrail.slint is what moves it.	2026-09-07 20:00:40 +02:00
dtourolle	de32c04a68	Dock the develop column under the photograph on a tall window ... D-N2 dismissed portrait with one number: a 12-inch tablet is about 1024 logical pixels across, which clears the expanded breakpoint. That was worked out for a 4:3 panel. The tablet's is 3000 by 1920, and on that aspect a column beside the photograph in portrait leaves it a strip 540 wide and 1456 tall: a 3:2 frame gets 540 by 360 where a column below it would give 900 by 600, and the portrait frame gains too. D-N7 records the decision: a third property beside the layout class, derived from the window's aspect with hysteresis, that lays the same rail, canvas and column out on the other axis. Not a sheet, not a second layout, and the rail does not move. N6 measures the device the numbers were guessed for, N7 does the frame with the stack stretched as a stopgap, N8 moves the develop callbacks onto a global so the panels can be declared twice cheaply, and N9 is the three-column composition the dock's width is actually for. N5's "no strip along the bottom" is struck where D-N7 reverses it and kept where it does not.	2026-09-07 20:00:40 +02:00
dtourolle	e13d3a54fc	Watch the mask tools work, rather than reading that they do ... A still frame cannot show what makes these tools right or wrong. What matters is how the mask *moves*: whether a stroke lands where the finger went, whether a subtraction takes away only what it covers, whether an erase inside a correction punches through the selection underneath. Every one of those is a sequence, and the test suite asserts single pixels. So this renders the sequences. A synthetic photograph, one frame per step of each mode — painting, erasing, joining a part and taking it out again, inverting, and sweeping the edge controls — as PPM, which ffmpeg turns into a GIF in one line. It runs headless, needs no RAW and no model, and takes a few seconds. It is also the honest answer to "show me it working" while the tools are still being wired to a finger: this is the pipeline itself, not a mock-up of it, and a fault in the fold shows here as a frame that looks wrong.	2026-09-07 20:00:40 +02:00
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	9ede23073d	Specify the tools that edit a mask once the model has drawn it ... The auto masks arrive in a second and cannot then be changed by a pixel: no brush, no way to cut one selection out of another, no way to drag a boundary that stopped inside a shoulder, and no way to see the alpha a layer actually produces — the canvas overlay draws what the model detected, not the mask. docs/mask-editing.md is how that closes. A layer stops holding one source and holds an ordered list of parts, each naming how it joins the mask before it, so painting on an auto mask, subtracting, and intersecting a subject with a luminance band are all one mechanism. Notes what the tree already has (the whole brush is written and reachable from no control), what the set operations actually cost (three blend states, no new texture), why the edge push is a warp rather than a local morphology, and why painting has to draw incrementally. Ends with the four decisions the build needs first.	2026-09-07 19:59:44 +02:00
dtourolle	1e171c6d31	Let a collection be picked up, rearranged, and emptied after the fact ... Collections could be made and filled and never reorganised. Nesting had a drag; un-nesting had nothing, in either direction — "All photographs" refused every drop, which is right for a photograph and wrong for a collection, which has a top level to be returned to. So a collection put inside another was in there permanently. Right-click deleted an *empty* collection outright and refused otherwise, which is wrong in both directions at once: destructive with no confirmation, and no way at all to delete a collection that held anything without emptying it by hand, child by child. And a photograph could only leave the collection the grid was scoped to, since that is the only one a button in the header can name — the cell's badge says a photograph is in three collections and never which three. Three ways in, one vocabulary: **Hold a row.** The tree is inside a Flickable, which claims any drag beginning inside it, so with a finger a drag on a row is a scroll until something says otherwise. The hold is that something. It lifts the row — drawn before anything moves, so the gesture says it has been understood — and then what the user does decides which of two things they meant: move, and it is a rearrangement; let go, and it is the row menu. The same fork the grid already uses to tell hold-to-select from drag-to-file. `decide_release` is that fork, and it is tested, because getting it wrong one way puts a sheet over every tidied tree and the other way makes the menu unreachable by touch. **The row menu.** Rename, new collection inside, move to top level, keep offline, delete. Deleting asks once when there is anything to lose and says what survives: the photographs stay in the library, and nested collections move up rather than going with it — which is what the catalog does, and what a user would never assume. An empty collection goes on the first press, because a dialogue about losing nothing is how people learn to dismiss dialogues. **"Collections…" on a selection.** Every collection the selection is filed in, each with a count — "3 of 40", so nobody takes forty photographs out of a collection thirty-seven were never in — and a way out of any of them without navigating there first. The long press used to open the offline question by itself. That question is one item in this menu now: there is one hold per row, and while it was spent on a single action nothing else the tree can do had a touch route at all. Nothing is lost — the tray on the row keeps its tap, and the question gains a full-width control in place of a 30px icon in a row shorter than the touch minimum. The row-press handler moves to `collections_ui` with the rest of what a collection row does; it lived in `library_ui` only because it opened that prompt.	2026-09-07 19:59:44 +02:00
dtourolle	577bbd82b0	Return the action the drag offered, not the one this row prefers ... Slint negotiates a drag action between source and target, and the runtime clamps whatever `can-drop` returns against the set the source allowed: an action outside it becomes `none`. Both drop targets here named a constant instead of echoing what was on offer, and each named the wrong one for half its traffic. A collection row takes two kinds of payload. Photographs come from a DragArea allowing `copy`; a collection being nested comes from one allowing `move`. The row asked for `copy` unconditionally, so images filed correctly and every collection dropped on a collection was refused — nesting by drag has never worked. The trash had the same fault mirrored: it insisted on `move` while the grid's cells allow only `copy`, so it refused every photograph dragged to it. Neither failure had anything to see. A clamped action is delivered as a refusal, which looks exactly like a target that declined on purpose, so the drag simply did nothing and left no error to search for. `decide_drop`'s Reparent branch was tested and passing throughout. It tests the decision, not the negotiation, and nothing was reaching it.	2026-09-07 19:59:44 +02:00
dtourolle	bac5801618	Ask which collections a selection is filed in, and how much of it ... `collections_for_image` answers this for one photograph and has no counts, which is enough to badge a cell and not enough to offer a removal: with forty selected and three of them in "Iceland", a sheet that says only "Iceland" invites the user to take all forty out of a collection thirty-seven were never in. `membership_of` returns the count alongside the name so the row can say "3 of 40". Chunked over the image list rather than one `IN (...)`, because the list is a selection and a select-all makes it as large as the library — past SQLite's bound-parameter cap on exactly the gesture most likely to produce it. Counts are summed across chunks, so the answer is the one the unchunked query would have given. Smart collections are excluded by construction: they have no member rows, so there is nothing a removal could do.	2026-09-07 19:59:44 +02:00
dtourolle	af89433aee	Offer the lens profile as a tick box, since applying it silently reads as absent ... The develop panel's Optics group is three manual sliders: distortion, chromatic aberration and lens vignetting. The automatic correction was already there — the file's EXIF lens is matched against the bundled Lensfun database on open and the coefficients are fanned out to all three — but nothing in the interface said so except a line of grey text under the camera reading "· corrected", and there was no way to decline it. From the outside that is indistinguishable from the feature not existing, which is how it was read. `dr-lens` states the rule this breaks: an automatic correction that silently does nothing is worse than one the user can see is unavailable. The caption satisfied the letter of it and not the point — a photographer looking for "apply the lens profile" found three sliders and no switch. So the profile is now a control. It is a capability rather than a flag on the session, because everything a photographer sets travels one road: the capability list feeds the generated panel, `Preset` captures it, the sidecar stores it and the undo stack replays it. A bool on the side would have needed adding to each of those four by hand and would have been forgotten in at least one — which is exactly how the mask stack came to be missing from the history. It is on by default, which is what `switch_on` is for: the coefficients are a measurement of the lens that took the photograph, so accepting them is neutral and declining them is the edit. The sidecar therefore stores nothing for the ordinary case and the correction still happens. The switch appears only where a profile was matched. A tick box on a photograph whose lens the database has never heard of would be a control that looks available and does nothing, which is the failure the rule above names rather than an instance of following it — those photographs are told "· no profile" in words instead, and one whose box is unticked now says "· profile off", which is a third fact and not either of the other two. Two things had to be built underneath. `ParamKind::Bool` was in the core's closed enum and mapped to a row kind here, and had no control behind it in `adjust.slint`: a parameter declaring itself a switch was flattened into a row that drew nothing at all. Nothing shipped had one until now, so the gap cost nothing and was invisible. And `Check` self-toggled, which is right for a settings page that owns its value and wrong for a panel row that is a view of the edit graph — the click would have answered by replacing the binding with a literal, and the next undo or pasted preset would have moved the value with the tick left where the finger put it. It now takes `controlled`, and the generated row uses it. The manual sliders are unchanged and still trim whatever the profile leaves, so switching it off is "correct this by hand" rather than "stop correcting".	2026-09-07 00:27:47 +02:00
dtourolle	2cd49d1cb7	Measure the rail by counting it, so it can scroll instead of clipping ... With the adjustment groups in the rail, a short window silently lost them. At a 1500x680 window the rail drew Photo, Compose, Local, Repair, the seam and "All", and then stopped: Optics, Light, Colour, Effects and Detail were not scrolled off, they were gone, with nothing on screen to say so. The develop view's primary navigation, unreachable by any means. The Flickable was put here to prevent exactly that, and it could not, because its viewport asked the layout how tall it wanted to be while the layout was already taking its height from the viewport. Slint settles that cycle by handing back the height it was given, so `max(self.height, preferred-height)` could never exceed `self.height` and there was never anything to scroll. Counting breaks the cycle. Every entry here is a fixed height by construction — a tool is `rail-entry-height`, a group is a touch target — so the content is six plus four fifty-fours plus a gap plus a touch target for each group and "All", which is exact rather than an estimate and depends on nothing that depends on it. Four tools and five groups come to 498, against the 340 a 680-pixel window leaves at 2x, and the difference is now scrollable rather than absent. Found by shrinking the window with the groups forced into the rail. The interaction itself is unverified: synthetic input does not reach a Slint window on this desktop, and the tablet was disconnected, so what is confirmed is the arithmetic and the clipping it explains, not the scrolling it should restore.	2026-09-07 00:17:08 +02:00
dtourolle	3dc7c184ee	Optimise for release only, since every edit pays for a dev build ... Dependencies were built at `opt-level = 2` even in dev, because wgpu and image decoding are slow without it. That is still true, and it is what this gives up: a debug run of the app, and the decode- and GPU-heavy tests, are slower than they were. What it buys is that nothing has to be optimised before it can be compiled. That cost was paid on every edit, in every worktree, whether or not anything was ever run — and there are sixteen worktrees, each with its own target directory and no shared cache, so it was paid sixteen times over. `[profile.release]` is untouched: `lto = "thin"` and `codegen-units = 1` still apply where the speed is actually wanted. If one crate turns out to be the one that makes a test unbearable, raise that crate alone rather than restoring the blanket rule; the manifest says how. Incremental compilation is now on as well, but that lives in `.cargo/config.toml`, which is untracked and per-checkout — so it is a local change on this machine, not part of this commit.	2026-09-06 20:17:53 +02:00
dtourolle	3f6dbce2aa	Name a lone control after its operation, so three cannot all read "Amount" ... The Detail group ended with three consecutive sliders labelled "Amount" and nothing to tell them apart. They are dehaze, clarity and texture: each declares exactly one parameter, and `ops/README.md` tells an author to reach for the `amount` kind first, so all three named it the same thing. The panel withholds a heading from a group of one, and the reasoning it gives is sound — a lone control names itself, and the group reset it loses costs nothing because the slider already resets on double-click. But that argument rests on the parameter being named after what it does. It holds for exposure, contrast, vibrance, saturation and brilliance, whose single parameter shares the operation's name, and it fails for the three whose parameter is called after its kind rather than its subject. So a lone parameter now takes its operation's label — the name the withheld heading would have carried. For the five that already agreed, nothing changes. Found on the tablet, and only there: every row was correct, every label resolved, and the panel was still unusable. The test that guards it asserts over the real chain rather than a fixture, because the fault was a property of what is actually declared — a fixture would have had to be written to reproduce it, and would then only have proved itself.	2026-09-06 19:01:54 +02:00
dtourolle	124b2d99c6	Take the first control that moves the picture, not the first one drawn ... `showing_the_original_leaves_the_edit_exactly_as_it_was` set row zero to its maximum and then asserted the photograph was modified. It was not, and the test failed on its own premise rather than on the thing it exists to check. `EditGraph::capabilities` puts the lens corrections at the head of the list, matching where they sit in the shader. Those carry profile coefficients rather than parameters, so with no profile loaded a slider on one is a control with nothing behind it: the graph stays neutral and the premise assertion fires. The test was written against a panel whose first row happened to be an adjustment, and it stopped being one. So it now walks the rows until it finds a control that actually changes the edit, which is what it meant by "row zero" all along. Still addressed by index, so it still names no operation, and it no longer depends on where in the chain the first *adjustment* happens to sit.	2026-09-06 19:01:53 +02:00
dtourolle	3994caba12	Write down the develop gestures, since only their author knew them ... FR-UI-4 says a gesture with no visible counterpart is a feature only its author knows about, and the vocabulary the application actually publishes had two sections in it — the library grid and people. Develop had none. Every one of its gestures was documented in the comment beside the `TouchArea` that implements it, which is where the previous sixteen were before this scanner existed, and unreachable to anybody not reading the source. Thirteen now carry tags: magnify by pinch or wheel, pan a magnified frame, fit and 1:1, hold to see the original, sample a neutral, undo and redo, step through the folder, reset one control, show or hide a mask layer, choose a group of adjustments, and copy and paste the settings. Each has a pointer and a touch route, so none of them is keyboard-only. Three bindings were genuinely missing and are added here rather than merely described. Ctrl+C and Ctrl+V for the settings clipboard, which the Settings panel's own comment has claimed existed for as long as the panel has and nothing bound; and [ and ] to step through the adjustment groups. The groups are whatever the operation set declares itself to be about, so there are as many as the pipeline has and no key can name one of them — stepping is the binding that survives a node being added, and "everything" is part of the cycle rather than a way out of it. Two are described and not bound. Resetting a control from the keyboard and toggling a mask layer from the keyboard both need a notion of which control or layer has focus, and the generated panel has none — the rows are a model the repeater rebuilds, and inventing a focus ring for them is a larger change than a keyboard shortcut. Both are reachable by pointer and by finger, and the tags say so rather than promising a key that is not there.	2026-09-06 19:01:52 +02:00
dtourolle	901f51e6c4	Point at something grey and let the pipeline work out the rest ... FR-DEV-3 has asked for "white balance (temperature/tint, and picker)" since it was written, and only the first half existed. `WidgetKind::WhitePoint` was in the vocabulary and `develop::supported` answered false for it, so the node degraded to two sliders — correct behaviour that had quietly become the only behaviour. Sampling a neutral is the first move of the global tonal pass and every colour judgement afterwards is measured against where the grey was put, so guessing at two sliders until a wall stops looking green is the wrong way round. The awkward part is that a picker genuinely needs to know how far a hundred units of temperature move red against blue, and that number is declared in the node's own file. So the inversion lives in `dr_pipeline::neutral` rather than in the interface: the canvas hands over a colour, the core finds the operation that asked to be driven by a pixel and bisects its declared response until the sample comes back grey. Nothing in `ui/` names white balance, and nothing holds a second copy of a response that would be wrong the first time somebody adjusted the range. A bisection rather than a closed-form inverse because only monotonicity is part of the bargain — the expression is free to become a table tomorrow. The result is rounded to the precision the control is drawn at, which is not cosmetic: unrounded, sampling something already neutral lands a ten-thousandth off zero, and the photograph comes back modified with an undo step for a correction of nothing. On the panel side this needed one distinction the generated path was missing. `is_on_canvas` was being read as "and so the panel draws nothing for it", which is right for a crop — four edge fractions are not controls anyone drags in a list — and wrong for an eyedropper, which *writes* temperature and tint and leaves them exactly the controls a photographer reaches for next. So a sampling widget keeps its sliders and puts the affordance that arms the canvas in the group's heading, built like the reset beside it. One click, one sample, one history step: `Edit::Action` never coalesces, and there is no hover preview to fill the stack with temperatures nobody chose. Declaring the presentation also groups temperature and tint under one undo step, where they were two. That follows from what `Presentation` means and reads correctly — white balance is one decision — but it is a change, and worth saying so.	2026-09-06 19:01:52 +02:00
dtourolle	2584b9ecbc	Hold one key to see the photograph before you touched it ... FR-DEV-7 asks for the current edit against the unedited original and nothing implemented it. What the develop view had was history navigation, which *changes* the edit rather than previewing against it — so the only way to look was to undo, look, and redo, and that puts two real steps on the stack at exactly the moment a photographer suspects they have overcooked a frame and is least sure of what they are doing. Holding the "Before" button, or backslash, renders the graph with every adjustment stripped and hands it straight back afterwards: the same suspend-render-restore shape the crop overlay already uses to show an uncropped frame and an export uses to suspend the zoom. Nothing is recorded, no rows are re-synced, and the photograph is still modified when the key comes up — the panel goes on describing the edit the photographer has, because only the canvas is answering a question. The framing deliberately stays on. A held comparison is a question about tone and colour, and re-cropping the canvas under someone's thumb would move the detail they are comparing; worse, the zoom is a rectangle of the *framed* image, so dropping the crop at 4× would quietly show a different part of the photograph rather than the same part unedited. What the crop took away is already compared in Compose, which shows the whole frame. Not a split screen: that halves the working image on the tablet this column was sized for, and the comparison photographers describe making is a flick back and forth rather than two pictures side by side. Press-and-hold is one gesture on a finger and on a mouse, which is what FR-DEV-3b's mapping wants, and it has no mode to be stranded in — the button reports both edges, so a press the system cancels puts the original down too.	2026-09-06 19:01:51 +02:00
dtourolle	9b674a88d8	Let the photographer look at the pixels, and keep looking ... Noise reduction and capture sharpening are judgements about individual pixels, and at a fitted view several of the file's pixels are averaged into each one on screen. The frame therefore looks cleaner and softer than it is, the photographer corrects for a softness the display invented, and over-sharpening is the documented result. Nothing in the develop view reached 1:1 at all: the wheel and the pinch zoom by ratios, the double tap dropped straight to fit, and the only readout was a percentage nobody was aiming at. So the double tap now does what FR-UI-4 always said it did — toggle fit and 1:1 — and the zoom readout, which used to be a dead "Fit" button on a fitted photograph, becomes the way in when there is nothing to clear. Z does the same from the keyboard, and the back gesture goes out through the same toggle so putting the magnifier down really puts it down. 1:1 is computed from the file's own resolution against the viewport rather than fixed at some multiple, because that is the only version of it that answers the question the two detail controls are asking. The point being inspected and whether the magnifier is up are held beside the session rather than in it, on the argument focus peaking already makes: a session is one photograph and this is a way of looking at a folder of them. Checking the same eye across forty portraits is the reason to reach 1:1 in the first place, and a magnification that reset with the session would make that forty zooms and forty pans instead of forty keystrokes. It stays a viewing state throughout — the view is kept out of `is_active`, `output_size`, the sidecar and the export, and an export still suspends it — so none of this reaches the file.	2026-09-06 19:01:50 +02:00
dtourolle	43652bd613	Say where the positives really come from, not where they were going to ... `calibrate.rs` claimed its positive pairs came from user confirmations "then burst siblings, since FR-CULL-5 already groups bursts", and repeated it beside the pair floor: "the positives are bootstrapped from bursts and a handful of early confirmations". Neither is true and neither ever has been. Nothing in the workspace pushes a burst pair into a `Pairs`; nothing pushes any pair at all outside this file's own tests. The sentence was written while both halves of docs/faces.md §8.1 were being planned together, describing a source that was going to exist, and it has read since as a description of what the code does. The distinction matters more here than in most comments, because this file is the one place in the subsystem allowed to say what a similarity *means*. A reader who believes the fit is drawing on bursts believes a young library is gathering positives on its own, which is precisely the opposite of the state FR-CULL-9 legislates for — a library with no fit, no valid calibration, and a reference curve it must not present as a measurement of itself. The floor of 200 positive pairs looks arbitrary under the wrong story and obvious under the right one: confirmations arrive one at a time, from a person. So the comment now says what is here — a positive is a pair confirmed onto one person, and there is no second source — and keeps the burst idea where it belongs, as §8.1's proposal, with the two reasons it is not in the code: this crate is handed cosines and cannot see a catalog, and the purity of a burst pair is a thing to measure before it is a thing to trust. No behaviour changes; the arithmetic is untouched.	2026-09-06 19:01:50 +02:00
dtourolle	1c5c55b4c9	Let the photographer say which frame the burst stands for ... `choose_representative` has been in the catalog since the grouping landed, with tests behind it and nothing calling it. So the frame a folded burst drew was always the earliest one, and the only way to disagree was to open the group and leave it open — which is to say there was no way to disagree at all, because a burst that stays open is a burst that was never collapsed. The earliest frame is the right default and it is deliberately not a judgement: nothing here scores a photograph, and FR-CULL-5 names the failure that rule avoids. But the whole point of a burst is that one of the twelve is better than the other eleven, and the person who knows which is the one looking at them. So a ring on each frame of an open group, ticked on the one the group folds to. It is drawn only while the burst is open, because that is the one moment the alternatives are on screen to be compared — offering the choice on a folded burst would be asking about frames it is hiding. Bottom right, opposite the count in the other corner, clear of the flag and the collection badge and, deliberately, of the trash target: a slip between the ring and the fifth star sets a rating, which is the harmless direction for an ambiguous press. The mark stays live on the frame that already wears it. A disabled TouchArea would let the press fall through to the cell behind it, so tapping the one ring that is ticked would have opened the photograph — and pressing it is a thing the user may mean anyway: it records the choice the default was making silently, which then survives a regroup that finds an earlier frame. Choosing repaints the badges instead of reloading the window, which is what separates it from folding a group up. Folding changes what the grid's query returns; this changes only which cell wears the tick, and the tick has to leave the frame that was carrying it, so the whole window is refilled in the one statement `sync_badges` already runs. The gesture is documented where FR-UI-4 requires it to be documented: in a tagged comment beside the control, which is the only copy. The gesture book, the gesture document and the requirements matrix are regenerated from the tree alongside it.	2026-09-06 19:01:49 +02:00
dtourolle	5fa4c0772b	Speak the sidecar format every other editor already reads ... FR-CAT-13 asked for standard XMP and nothing in the tree parsed or wrote a byte of it. `keywords.rs` mentioned `dc:subject` in a comment about what a keyword's text is for, `dr-export`'s metadata module said "neither is read by `dr-decode` today" about its own half, and `dr-preset-xmp` reads a different file for a different requirement. So a library imported from Lightroom could come in and never go back out: a one-way door, which is not a thing a photographer walks their archive through. `core/dr-xmp` reads and writes the properties the requirement names — `dc:subject`, `lr:hierarchicalSubject`, `xmp:Rating`, `xmp:Label` and the IPTC core fields — from whichever shape the file happens to use. A property may arrive as an attribute or as an element, inside a Bag, a Seq, an Alt or no container at all, because the specification is not what wrote the file; so one collector takes whatever is in a property and the declared shape decides only how many values survive. `xmp:Rating="-1"` is modelled as Adobe's rejection rather than folded into zero stars, since DarkRoom keeps those on two axes and the mapping belongs where both are visible. Writing is a rewrite rather than a serialisation, and that is the whole design. An XMP sidecar is a shared document: the file beside a raw carries somebody else's `crs:` settings and comments and namespaces, and rendering our record over it would be data loss on every photograph but the first. The rule is stated once, in the crate documentation and in `PROPERTIES`: DarkRoom owns exactly those properties, identified by namespace URI and never by prefix, and nothing else in the document. Everything unowned is copied through byte for byte. A `Description` left empty once our properties come out of it is withdrawn, which is what keeps a rewrite idempotent instead of adding a husk to the file on every save. Precedence is settled conservatively, because a standard XMP carries no revision and no device and there is nothing in it to order two edits by. Keywords union, following the rule `dr_catalog::merge` already makes for assignments; every other field is taken only where DarkRoom holds none, following `Version::merge`'s judgement rule, and a genuine disagreement is reported rather than resolved so a caller can offer the reload the requirement asks for. What is deliberately left open — when a reload may happen without asking — is written down in the module rather than picked silently. No new dependency: quick-xml was already in the tree for WebDAV and for Lightroom presets. Nothing above the crate calls it yet, and `outstanding.md` now says so along with the two smaller gaps, GPS and the filename convention.	2026-09-06 19:01:48 +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
dtourolle	81b1ae8c42	Measure the haze from the picture, and divide it back out ... Four files named dehaze as a member of the compositional detail family — `detail.rs` twice, `dr-gpu`'s detail module, `ops/README.md` and `capture_sharpen.rs` — and no such node existed. Every one of them was describing the family by listing clarity, texture and a control the photographer could not reach. Haze is the one degradation the controls already in the chain cannot remove, and the reason is spatial rather than tonal. Scattering composites an airlight over the scene in proportion to distance, so the lift is per-pixel: a black point that clears the mountains crushes the foreground, and a contrast curve that clears the mountains does the same. So the node has to estimate the transmission at every pixel, which is the dark-channel prior — the local minimum over the channels and over a patch is the airlight that has been added there — and then invert the scattering model with it. The airlight is taken as neutral and as unit, which removes the one part of the published method this stage cannot perform. Estimating it properly is a whole-frame reduction, and the detail chain has none: it hands each pass the pass before it. It is also unnecessary, because white balance is the first node in the chain and has already driven the illuminant to grey, so only the magnitude is unknown — and an unknown magnitude on the veil is a scale factor on the amount slider, which the photographer is setting by eye regardless. The patch is a fraction of the frame's shorter edge, through `RenderScale::frame_fraction`, and never a count of pixels. It has to be wide enough to contain something dark and narrow enough that what it measures is still local, and both of those are statements about how much of the composition it covers — so it must cover the same proportion of the picture on a proxy as in the export, or the file is sharpened for a patch three times narrower than the one that was tuned on screen. Affording it needs an identity a Gaussian does not have. Erosions compose by adding their structuring elements, so the minimum over a run of d followed by the minimum over k points spaced d apart is the exact minimum over the whole kd window. At the square root that is 16 taps rather than 61 at 4K, and it is the same filter rather than an approximation of one — which is the difference from the strided kernel `local_contrast` refuses, where sampling an image that is not band-limited aliases into the base and comes back as mottling. It runs first among the compositional detail nodes, at order 125: after noise reduction, because dividing by a transmission below one amplifies the noise in the veiled distance by exactly the factor it recovers the contrast by, and before clarity and texture, coarse before fine, so that their base is computed on the picture the veil has left rather than on a modelling about to be divided out. What it cannot honour is the placement dehaze most wants. It shifts colour — it subtracts a grey term and rescales, so saturation changes wherever the veil is thick — and the colour work would ideally be correcting the picture that leaves here. The detail stage runs as a group after every point operation, because a neighbourhood pass is a separate dispatch over a texture the fused pass has finished writing, so an order placing this node ahead of `vibrance` would be a lie the chain cannot tell. Interleaving would mean splitting the fused pass in half around it, at the cost of a second full-frame dispatch and intermediate for every edit in the catalogue whether it dehazes or not. The declaration records that rather than leaving it to be rediscovered. FR-DEV-18 is added to the requirements register alongside it. The tag had nowhere to point, and an orphan tag fails the traceability gate rather than quietly counting for nothing.	2026-09-06 19:01:47 +02:00
dtourolle	7c3e1d2c54	Let the shadows and the highlights carry a colour the picture never had ... The colour mixer is the only chromatic control in the chain, and it can only turn a hue that is already in the frame. Ask it for cool shadows against warm highlights and it has nothing to take hold of: the shadows of a correctly balanced photograph are near enough neutral that there is no band there to turn, and a monochrome conversion hands it a picture with no hue in it at all. Split toning is the oldest look in the book and every developer worth comparing against ships it; there was no way to reach it from here. So colour_grading, declared like any other node — a hue and a strength for the shadows, the midtones and the highlights, and a global cast over the frame. It targets a tonal range rather than a hue, which is the whole difference between the two controls: it puts colour where none was rather than turning what it finds. It sits at 105, after the mixer has had the last word on the colours that are in the picture and before the detail stage. The mechanism is one helper. Three cosines 120 degrees apart are the hue wheel written directly as an RGB direction, and their sum is zero at every angle, so exp2 turns them into three gains whose product is exactly one — a cast tilts the balance without moving the level. A grade that doubled as an exposure change is the failure that has the photographer chasing brightness with a colour slider, and it is corrected with a control that cannot reach it. The three tonal weights partition the scale rather than overlapping, the midtones being whatever the two ends leave, so setting all three to one hue is exactly the global cast and a split tone does not colour its own midtones as a side effect of its halves meeting. Full strength is half a stop on the leading channel, the ceiling white balance already holds itself to. Neutral is declared rather than inferred, which is what `active:` is for. A hue with no strength behind it is a direction with no distance, so under the default rule nudging one would have put the node into every fused shader for a change nobody can see. Summing the strengths is zero exactly when all four are, and they cannot go negative to cancel each other. The opposite reading — neutral as "nothing has been touched" — fails the other way round: red is hue zero, so a grade toward red never moves a hue off its default and would never have been applied at all. It asks for a colour wheel, the widget the descriptor vocabulary has been carrying with no operation behind it. Nothing draws one yet, and that is fine by construction: the panel takes the first widget it implements and falls through to sliders otherwise, so this arrives as eight ordinary controls that work. Each parameter is named for its own range for exactly that reason — in a flat list, four sliders called "Hue" are four controls nobody can tell apart. FR-DEV-12 is written into requirements.md beside it. A TRACES tag naming a requirement that is not defined there is an orphan, and the traceability gate fails on those rather than quietly counting them. The label catalogue gets one line for the operation's display name; the eight parameters derive correctly and are left to.	2026-09-06 18:51:40 +02:00
dtourolle	efa9d84aad	Correct the lens first and settle the grain last ... `Attribute::ALL` has claimed since it was written to be roughly the order a photographer works in, and 474dcf0 moved `Compose` to the front on exactly that argument. Both ends went on contradicting it. `Optics` sat fifth, so the column offered the lens corrections after the tones they change. Removing a vignette brightens the frame; an exposure judged before that correction has to be judged again after it, which is the definition of the wrong order. `Detail` sat fourth, so sharpening and noise reduction — the only work here that depends on everything above it, and the only work that cannot be judged at fit view at all — were offered before the lens had even been put right. So `Optics, Compose, Tone, Colour, Effect, Detail`. `Optics` leads even `Compose` because it is not a decision about the photograph at all: it is undoing what the equipment did, a property of the capture rather than a choice. `Effect` after `Colour` is a look laid over a settled picture, and is the one slot that is genuinely arguable — a spectral film simulation declares `renders` and replaces the base curve, which is a case for treating it as foundational instead, and e235e99 filed film under `Effect` only days ago. The doc comment records that tension rather than pretending to settle it; an array of six cannot say "last, except when it is first". `decl::Attr::ALL` moves with it. It is the second spelling of one vocabulary, compiled by `build.rs` where `descriptor` is not visible, and the agreement test in `declared/mod.rs` zips the two positionally — that test is what caught the last reorder, and it would have caught this one. Nothing persists a position in this list, which is what makes the reorder safe rather than merely tidy. `Scope` packs one bit per attribute indexed by `Attribute::ALL`, but `bits` is private, has no accessor and no `serde`; what reaches a settings file is `develop.copy_attributes`, a list of names read back through `Attribute::from_name`. A photographer's copy scope survives untouched — only the order the names happen to be written in changes. 6a97fdf is why this is worth a commit now rather than a shrug: the contradiction was harmless while the list only fed a row of chips nobody reads in order, and stopped being harmless when the same list began driving a column read top to bottom. The matrix follows the two files' shifted line numbers.	2026-09-05 21:17:56 +02:00
dtourolleandClaude Opus 5	59917c5183	Call the tool Compose, since that is what its panel says ... The rail entry read "Crop" while the panel it opens is headed COMPOSE and the button leaving it said "Done Cropping". One mode, three names, and the odd one out was named after a single control rather than after the decision — which is what made cropping look like a category of its own in the first place. Straightening, the quarter turns and the flips are already in that panel, and perspective will be. `ViewMode.crop` keeps its name: it identifies a canvas interaction, which is exactly what it still is. Found by looking at the running application rather than by reading, which is also how the two halves of this were noticed to disagree at all.

dtourolleandClaude Opus 5	e235e99cce	Move the film to Effect in the descriptor that is actually read ... An earlier commit claimed to move `film_sim` from `[tone, colour]` to `[effect]` and did not. It edited `ops/film_sim.yaml`, where `attributes:` is read, validated against the vocabulary, and then dropped: a `rust:` node publishes its own descriptor, and the type still said tone and colour. The stock went on appearing in the Light group beside exposure and again in Colour beside white balance, exactly as before, and every test passed. Nothing caught it because nothing could. The declaration parsed, the parity tests compare ids rather than attributes, and an operation filed under the wrong groups renders perfectly. It surfaced only on screen, as a missing Effects tab — which is indistinguishable from a category that genuinely has nothing in it, and is precisely how `Optics` looked for as long as it was empty. So three changes rather than one: `FilmSim`'s descriptor declares `Attribute::Effect`, which is the move the earlier commit described. `attributes:` joins the keys a `rust:` node may not carry, beside `params`, `uniforms`, `wgsl`, `helpers`, `define` and `label`. The rule was already written — "its descriptor comes from the type" — and attributes were the one field that slipped past it. A key that is silently ignored is worse than one that is rejected, because it reads as though it worked; the eight hand-written declarations lose a line that never did anything. And a test asserts that every attribute the chain carries reaches the tab strip. That is the property that was actually broken, and its failure mode is invisible from every direction: the controls exist, they are in the shader, and there is no way to filter to them.

dtourolleandClaude Opus 5	6a97fdf6f9	Put the adjustment groups in the rail where a finger is driving ... Reported from the tablet: the tool rail is very useful there, and the same interface under a mouse and keyboard is not. That is `ui-navigation.md` D-N2's central assumption failing in use, and the interesting part is which half of it failed. D-N2 was right that platform is the wrong axis and width is the wrong axis: a tablet in landscape wants what a desktop wants, and a desktop window dragged narrow wants what a small screen wants. `apply_layout_class` still decides the layout class from the window and nothing here changes that. What D-N2 got wrong is the sentence "touch changes hit regions, not layout" — it identified input as the real difference between the targets and then assumed that difference could never reach the layout. Two controls answer one question — which group of adjustments am I looking at — and neither is better in general. A horizontal strip above the column is one gesture to a target the eye has already found, and it pans when the operation set is rich, so a group can sit off the end with nothing saying so: a pointer user tolerates that, a finger user never discovers it. The same list down the rail is every entry visible at once, each finger-sized, on the edge of the screen the hand is already holding, and it costs no width because the rail is already there. So `ToolRail` grows a second section, and `GroupStrip` stands down when it does. The two are never both on screen, which is why they can share `adjust-tab-picked`: Rust is not told which was pressed and has no reason to want to. Mode and group stay independent axes as N1 requires — one entry lit in each section, and choosing a group while a tool is held still filters without putting the tool down. They stay drawn differently, which N1 also required. The tools fill with `active-dim` and invert their ink; the groups take a bar down the leading edge — the strip's underline turned ninety degrees — so a lit entry says which kind of state it is without the reader having to remember which section it was in. The rule between the sections is the second signal. The rail scrolls now. Its own note argued against a Flickable because "this list is four entries written in this file"; with the groups in it the list comes from the operation set, which is exactly the "something the user's data decides" that note excluded this control from. The axis is input, and it is a preference because the automatic answer is a guess that cannot be made reliable. Neither platform can be asked what the user is holding: an Android tablet in a keyboard case is being driven like a desktop, and a touchscreen laptop is whichever its owner says. `dr_plat::is_touch_first` reports the usual case per platform, and `GroupNavigation` lets it be overridden. Settings names what Automatic resolves to on this device rather than leaving it to be found by pressing. D-N6 records the reversal beside the decision it reverses, including the half that still stands and the question it opens: whether Local is a mode at all, or a scope that would collapse the two sections into one list.

dtourolleandClaude Opus 5	474dcf0bf6	Let Compose lead the attributes, as their own doc always said ... `Attribute::ALL` claims to be "roughly the order a photographer works in" and then listed framing fifth, behind tone, colour and detail. Framing is the first decision made about a photograph and the one every later judgement is made inside — there is no sense balancing tones across a frame about to lose a third of its width. The contradiction was harmless while the list only fed a row of chips nobody reads in order. It stops being harmless now that the same list drives a column read top to bottom. `declared::Attr::ALL` moves with it. The two are separate spellings of one vocabulary and a test asserts they agree, which is what caught this rather than the order silently disagreeing between the YAML front end and the crate.

dtourolleandClaude Opus 5	1ad35e2b87	Read the library's sidecars, so a cull done elsewhere arrives ... Judgements only ever travelled outward. A rating went to the catalog and to the photograph's sidecar, the sidecar reached the server, and there it stopped: the scan indexes files, `derived_sync` exchanges thumbnails, face shards and collections, `dr_catalog::merge` reconciles everything in a catalog except `versions.rating` and `versions.flag`, and the one sidecar reader that existed ran when a single photograph was opened in develop and handed its answer to the develop graph. `JobKind::ReadSidecar` was declared for exactly this when the job queue was written and was never enqueued or handled anywhere. The grid draws `versions.rating`. So a day of culling on the tablet could not reach the laptop by any path the application had, and the laptop's catalog says so plainly: 23,568 images, one of them judged. `pull_sidecars` closes it, off the back of work the scan already does. `dr_sync::scan` reports the `.drsc` files it meets in listings it was making anyway — no extra request, and a directory whose ETag is unchanged is still pruned before it is listed at all. A new `sidecars` table records the ETag of each one this device has taken in, so the fetch is one GET per sidecar that genuinely changed rather than one per photograph. A library nobody has edited costs nothing. The judgement is taken rather than maximised. The sidecar is the authoritative store and the fuse has already settled any contest between devices on `revision`, so lowering a rating from four to one on the tablet lowers it here — taking the larger would have refused every demotion the photographer ever made, which is most of what a second pass over a shoot is. A zero is the exception: it means *never judged*, not "judged zero", so a sidecar carrying none cannot erase a star this device holds. That is `merge_judgement`'s asymmetry and it carries the same known cost — clearing a rating does not propagate. A sidecar names a stem, so both halves of a RAW-and-JPEG pair are judged: they are one photograph (FR-CAT-11) sharing one document, and judging only one of them would leave the grid disagreeing with itself over which it drew. The `LIKE` that finds them is a filter, not the decision — `sidecar_path` is applied to every candidate, because a folder is entitled to contain a `%` and a rating landing on the wrong frame would be silent and permanent. Failing to read one is not a failure to scan: the ETag goes unrecorded, the ratings already here stay where they are, and the next scan tries again. The count is reported to the status line as well as the log, because a grid that silently gains three hundred stars is indistinguishable from one that has gone wrong — and because while this number was structurally zero there was nothing to tell the photographer their cull had not arrived.

dtourolleandClaude Opus 5	ca2a135e28	Let two devices name the same photograph's version the same way ... A version's uuid is the identity a cross-device merge keys on, and it was minted at random, per catalog, per image. Two devices indexing one Nextcloud library therefore held two different uuids for the same photograph — so the sidecar they shared collected a `default = 1` block each, `Version::merge` was never handed a matching pair to reconcile, and an afternoon's culling on the tablet did not exist as far as the laptop was concerned. `crate::merge` has said so in a comment since it was written: version uuids do not reconcile across devices, a uuid-keyed join unions nothing, so keywords are landed on the local default version instead. It named the problem and worked around it. `rating`'s own comment asserted the opposite — that generating the uuid here was what made it a cross-device identity — and `library::amend` repeated the claim. Uniqueness was never the difficulty; agreement was. `derived_version_uuid` computes it from `oc:fileid` instead. The server assigns that integer, every client pointed at the library sees the same one, and it survives a server-side rename and move — the three properties that already made `ASSIGN_BY_FILE_ID` prefer it to a content hash. The layout is a UUIDv8 (RFC 9562, an application-defined form) carrying all sixty-four bits verbatim across the variable fields with a fixed tag in the node field, so the mapping is injective by construction rather than by a hash's good behaviour, and a uuid in a sidecar can be read back to the file it belongs to by eye. A library with no server behind it has no shared identity to derive and keeps a generated one. The split is still reachable there if the folder is synced by something else; `Sidecar::fuse_default_versions` repairs that case rather than preventing it. Deriving it for new rows alone would have fixed nothing — every image in an existing library already has a version, so every one of them would have carried on writing to its own rival identity. `align_default_version_uuids` moves them, and runs from `schema::backfill` on every catalog open. It selects on the tag in SQL, so a catalog already realigned matches no rows and writes nothing, and it declines rather than fails where a virtual copy already holds the target.

dtourolleandClaude Opus 5	601c984894	Fold a photograph's rival default versions back into one ... Picking the newer of two default versions stopped the wrong edit being shown, but it did not close the split: the losing version stayed in the file, and a device holding disjoint work — a crop made here, an exposure change made there — still contributed only one of the two. Worse, the next write made it larger. `amend` looks its version up by uuid, neither of the two was ours, so the miss minted a *third* `default = 1` block and the file grew one rival per device per photograph. `Sidecar::fuse_default_versions` folds them down. The version with the highest `(revision, modified)` is the accumulator and every other default is merged into it as the remote, which is what makes the fold order-independent — `Version::merge` raises its own revision to `max + 1` as it goes, so merging a chain in ascending order stops being ascending after the first step and a third device would be dropped. Contested values resolve to the winner, disjoint keys survive from both sides because the merge is key-wise, and ratings come across under `merge_judgement`, so a device that never judged the frame cannot erase one that did. The result is a function of the file's bytes alone, so two devices that fuse independently reach the same document and converge instead of overwriting each other. Called wherever a sidecar is parsed: - `amend`, with the write's own uuid, so the fold lands on the identity this device is about to use and the lookup below it hits instead of missing. - `spawn_sidecar_fetch`, so opening a photograph shows everything done to it rather than whichever half won. - `drain_one`, because `merge_into` reconciles by uuid and would otherwise publish the split rather than resolve it. - `presets::load_local` and `save_local` — a local sidecar's folder may be synced by something else entirely, and gets the same split. A file with one default under the expected uuid comes back byte-identical, so this costs nothing on the ordinary write and no sidecar is uploaded merely for having been read.

dtourolleandClaude Opus 5	98fcf8e98e	Ask which edit is newer, not which uuid sorts first ... A photograph edited on two devices ends up with two `[version]` blocks in one sidecar, both marked `default = 1`. Five of the thirty-eight sidecars in the local cache are in that state right now. `default_version` answered with the first `is_default` it met in map order, and the map is keyed on uuid — so which device's work the photographer saw was decided by which randomly minted uuid happened to sort lower. On `IMG_20130625_0033` that is `0545c20a` over `679fe872`: a four-star rating from the twenty-first of August standing in front of the one-star made on the thirtieth, with nothing anywhere saying the newer judgement existed. Resolved by `(revision, modified)` instead, which is the discriminator `Version::merge` already uses — revision first so that a device with a skewed clock cannot win by claiming a later timestamp (FR-NC-8), and the timestamp only to break an exact tie. This makes the reader pick the right one. It does not make the two converge: the edit that lost is still in the file, and a device that holds disjoint work — a crop here, an exposure change there — still only contributes one of them. That is the next commit. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-09-05 16:13:49 +02:00
dtourolleandClaude Opus 5	a56baa9042	Let rustfmt have the assertion it reflowed ... The closure taken down to `&dyn Operation` needed its call site re-wrapped, and I wrapped it by hand rather than letting rustfmt decide: it fits on one line at the workspace width. `cargo clippy` was run on the change and `cargo fmt --check` was not, which is the whole of how it got through — the two catch different things and CI runs both.

dtourolle	f0ee53ec09	Merge: the optical corrections, connected at last ... Four files' worth of lens correction existed, was tested, and had never touched a photograph. `compose_warps` had no callers, `dr-lens` had no dependents, and `ops/vignetting.rs` had no declaration in `ops/` — so `Attribute::Optics` was a category the tab strip could only ever filter out for having no rows in it. Distortion, chromatic aberration and lens vignetting now render, carry their parameters through the sidecar and the undo stack, and take their coefficients from the Lensfun database when the file names a lens it knows. The panel says which of "no lens recorded" and "no profile for this lens" it is, because an automatic correction that silently did nothing is worse than one visibly unavailable. One real bug on the way: `lens.rs` and `framing.rs` both documented the shader's `p` as corner-normalised, and it is not — its length at the corner is `0.5 * length(aspect)`, about 0.901 on a 3:2 frame. Every Lensfun polynomial would have been evaluated short of where it was fitted, by a factor varying with the aspect ratio, which reads as a correction that is merely too weak. The category vocabulary moved with it. `Attribute::Geometry` is `Compose` — named for the photographer's decision rather than for the maths it shares with the lens corrections — and a film stock stopped claiming to be both tone and colour, which had put "Kodachrome" in two groups it belongs to neither of.	2026-09-05 15:35:44 +02:00
dtourolleandClaude Opus 5	2841eaf9a1	Take the layer-chain test's closure down to &dyn Operation ... `clippy::borrowed_box` is denied by the workspace lint set, and the closure added with the optics exclusion took `&Box<dyn Operation>` — a borrow of the box rather than of the thing in it, which says nothing the plain trait object does not. Caught by `cargo clippy --workspace --all-targets -- -D warnings`, which is what CI runs and what the workspace tests do not: a lint on test code only appears when the tests are compiled as a clippy target.

dtourolleandClaude Opus 5	c4ddcbe0f7	Look the lens up and say plainly whether one was found ... `dr-lens` has held a complete Lensfun lookup — distortion, TCA and vignetting coefficients from a lens name, a focal length and an aperture — with no dependents anywhere in the workspace. The three corrections it feeds now exist in the graph, so this connects the two and finishes the chain. The coefficient structs stay duplicated. `dr-pipeline` is organised around having no dependencies so its codegen is testable without a device or a database (ARCH §6.5a), and `dr-lens` carries an XML parser and 5.5 MB of profile data. Neither crate can convert to the other, so the conversion goes above both, in `develop.rs`, which is the only place that sees them together. Both traits grow the same defaulted door. The optical corrections do not sit on the same side of the fetch — distortion and CA rewrite coordinates and are `Warp`s, vignetting applies a gain to the pixel already there and is an ordinary node — and fanning a profile out by which trait each happens to implement would make the caller reason about that distinction. Each correction takes its own share of the whole profile instead, and `set_lens_profile` walks both lists identically. The lookup happens in `set_source_metadata` rather than in its caller, because that is the one place a session is told which file it came from. Doing it there makes it unforgettable, in the shape `FilmRebake` already uses for the other derived thing — and, more to the point, makes *clearing* unforgettable: a session that opened a second photograph while still holding the first one's profile would correct it for the wrong optics, invisibly, in a way that looks exactly like the lens. It needs the whole shot and not just a name. Distortion is interpolated across a zoom's focal range and vignetting depends strongly on aperture — a fast prime can be two stops down in the corners wide open and clean by f/8 — so a lookup missing either returns coefficients measured for a shot nobody took. Missing any of the three refuses rather than guesses. A profile is derived, not persisted: it comes from the file's EXIF and a database, so it is not a parameter, not in the sidecar and not undoable. What is an edit is the manual trim beside it, which each correction composes with the measurement — so a photographer can lean on it, override it, or work without one. `InfoPanel` gains a lens line, and it distinguishes three cases rather than two. `dr-lens` states the rule it exists for: an automatic correction that silently did nothing is worse than one the user can see is unavailable. A session with no header draws nothing, a header naming no lens reads "Lens not recorded", and a lens the database has never heard of reads "· no profile". Collapsing the last two would send somebody hunting for a profile that was never missing — which, for third-party and adapted glass, is the ordinary case.

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	e17b909d41	Connect the lens vignetting correction to the pipeline ... `ops/vignetting.rs` has carried a complete descriptor, polynomial, helper and test suite without an entry in `ops/`, so it was never in `chain()`. It reached no photograph and no panel, and `Attribute::Optics` was an empty category in consequence — filtered out of the tab strip for having no rows, by a chain that had never been given its only member. Declaring it needs the one thing the operation was written against and which did not exist. `wgsl_body` reads `radius`, and the module claimed "the composer publishes `radius` in the shader prologue for exactly this reason". It did not. `sample_source` now does, in both sampling branches, beside the `source_px` it already published for the same class of caller. It is corner-normalised there, which is the part that is easy to leave out. `p` spans ±0.5·aspect, so its length at the corner is 0.5·length(aspect) — about 0.901 on a 3:2 frame, not 1. Lensfun's polynomials are fitted against a corner radius of 1, so passing `length(p)` straight in evaluates every one of them short of where it was measured, by a factor that changes with the aspect ratio. It would have read as a correction that is simply too weak, which is indistinguishable from a bad profile. Both `lens.rs` and `framing.rs` asserted the normalisation `p` does not have; corrected. `order: 5` puts the correction ahead of the tonal stages, and the ordering is load-bearing rather than tidy. Recovering a corner means dividing by an attenuation below one — about two stops for a fast prime wide open — so run after the highlights have been rolled off and clipped, the lift has nowhere to go and the corners posterise instead of brightening. `layer_chain` now drops `Optics` as well as the neighbourhood operations. A local vignetting slider would have worked, which is what makes it worth excluding: `radius` measures from the centre of the whole photograph and a mask cannot move the optical axis, so it would lay a frame-centred radial ramp across the picture and multiply it by the mask. The existing exclusion covers operations that move and do nothing; this one covers an operation that moves and does something its name does not promise. The rule both share is now written down.

dtourolleandClaude Opus 5	8e7b1350bf	Name the frame's category for the decision, not the maths ... `Attribute::Geometry` becomes `Attribute::Compose`, and `film_sim` moves from `[tone, colour]` to `[effect]`. Two categories were doing the wrong job. "Geometry" describes what crop, straighten and the quarter turns do to coordinates — but it describes lens distortion correction exactly as well, and that is not a compositional choice at all. Naming the attribute for the photographer's decision is what separates it from `Optics`: one is what the lens did, the other is what they chose. The maths the two have in common is not the thing worth filing them under. A film stock declared both `tone` and `colour`, so "Kodachrome" appeared in the Light group beside exposure and again in Colour beside white balance — two places, neither of which is where anyone looks for it. It is neither: `Effect` is defined in this same file as "applied rather than corrected — a look, not a fix", which is what a stock is. That it moves tone and colour is true of every look, and is not what the attribute is for. `from_name` still accepts "geometry" on the way in. That string is persisted in `develop.copy_attributes`, and an entry it fails to parse is not an error — `presets::scope_for` logs it and drops it — so without the alias an existing settings file would have quietly narrowed what a paste carries. `name` writes the current spelling, so the file migrates itself the first time it is saved.

dtourolleandClaude Opus 5	95e854b5a2	Regenerate the gesture vocabulary over the library work ... `Traceability` stayed red after the matrix was regenerated, on its other gate: `gestures-check`. Same cause, second artefact. `docs/gestures.md` cites each gesture by `file:LINE`, and the library UI work moved the two selection-mode gestures down a hundred lines — 3923 -> 4032 and 3940 -> 4049 in `ui/dr-ui/ui/library.slint`. Nothing about the gestures themselves changed. `ui/dr-ui/src/gesture_book.rs` was already current, so this is the doc alone: 70 files scanned, 16 gestures, 2 places, gate PASS. Worth knowing for next time: `tools/ci-local.sh traceability` runs the self-test, the coverage gate and the matrix, but not `gestures-check`, so a clean local run does not prove this workflow green.

dtourolleandClaude Opus 5	c1069ce07e	Release 0.10.1 ... A bug fix release. Nothing here changes what DarkRoom is for since 0.10.0; it changes how often it does the thing it already claimed to do. The edits that went missing. A subject or category layer was stored as identity alone, on the reasoning that the pixels were reproducible by re-running the model — true, but nothing re-runs one except a photographer pressing "find subjects". So a reopened photograph rendered without its local adjustments and then saved that state back, and a batch export wrote three hundred files without the edits their photographer had made, over a log warning. The coverage now travels in the sidecar. Export also learned to write the photograph rather than the canvas, and to carry the photograph's header when the export is made from develop. Face indexing was reading previews. It ran against a proxy and then recorded the result as though it had seen the photograph, so faces smaller than the proxy could resolve were not missed, they were *concluded absent*. Indexing now runs on the native render, runs made against proxies too small to find a face are forgotten rather than trusted, and a sweep that fails everything says so instead of reporting a clean pass. Where you were. The photo roll opens on the frame it opened with, develop returns you to the photograph you were editing, the grid keeps its place when another screen covers it, and the photographer's position now travels between devices rather than being rediscovered on each. Startup. The catalog opens on a worker and the bundled models unpack on one, so a launch is no longer a page-by-page read on the way to the first frame; the app says it is starting before there is anything to say it with. The People rail builds the rows you can see, keeps portraits off the blocking path, and withholds the empty groups that used to fill it. Segmentation gained the half it was missing: the colour gate decided what belonged to a category and had no way to decide where its edge fell, so a refined sky kept the model's blocky outline no matter how the control was set. A marker-based watershed now puts each contour onto a real edge, and the refinement is a per-layer slider. Coverage 70.4% -> 70.6% (127/180).

dtourolleandClaude Opus 5	dabf63ed6d	Regenerate the matrix over the watershed and sidecar work ... `Traceability` has been red on master. The matrix records every tag as `file.rs:LINE`, so it goes stale two ways at once, and both happened here: - the `cargo fmt --all` sweep (710fcbc) moved lines under tags that did not otherwise change, which is drift with no change of meaning; - the segmentation and mask-storage work added tags and a requirement, which is drift that means something. Regenerated: 332 -> 334 files, 1058 -> 1086 tags, 179 -> 180 requirements defined, coverage 70.4% -> 70.6% (127/180). No code changes.

dtourolleandClaude Opus 5	f6c9343bcc	Ask the pixels where the edge is, not just what belongs ... The colour gate decided *what* was in a category and had no way to decide *where* its edge fell. A colour test has no notion of an edge. So a refined sky lost its flag and kept the model's twenty-pixel-blocky outline, and no setting of the control could move that outline onto the horizon. This adds the second half: a **marker-based watershed**. The mask is eroded to give two markers, and the flood runs in the ribbon left between them, meeting along the most expensive line it can find. The cost is a sum of terms exactly as docs/segmentation.md §2 specifies — the photograph's own edges, and the colour model's disagreement. ## Why this is not the watershed §15 threw away That path failed because the merge *ladder* collapsed: 45,808 basins reduced to one region plus specks. There is no ladder here. Markers prevent over-segmentation by seeding rather than by merging afterwards, so the one component that broke is the one component this does not have. The markers are also better than the textbook's. scikit-image derives them by thresholding the gradient — guessing where objects are — where these come from a model that knows what sky is. Marker selection is what normally goes wrong with this method, and it was already solved. ## The gate still runs, and it runs first A flood cannot replace the colour gate. It only refines contours that already exist, and there is no contour around a flag precisely because the model never noticed one — the flag in the tests sits forty-five pixels from the boundary against a ribbon of six. The tests caught this; the first version of this commit had the flood standing in for the gate and the flag stayed. So the gate goes first and *creates* the contour, and the flood then puts every contour — the horizon and the new hole alike — onto a real edge. ## Erosion that does not delete flagpoles Eroding by a cell and a half destroys anything thinner than three cells: a mast, a bare branch, and equally a strip of sky between two of them. Those would be left unseeded and the flood would fill them from whichever side surrounds them, so a flagpole would come back — and come back *confident*. Erosion therefore stops at the ridge of the distance transform. Whatever would otherwise vanish keeps a one-pixel seed down its centre, floored at `min_thickness` so a hot pixel does not qualify. That floor also moves the signal-versus-noise decision out of colour space, where it was a share of a fitted distribution nobody can picture, and into image space, where it is a width in pixels a photographer can see. ## Two modelling errors the outward test found Both were invisible while the refinement could only subtract, because the gate was multiplied by weights that were already zero outside the mask. The moment the boundary could move outward they decided the answer. **A diagonal covariance is wrong along a gradient.** Sky moves along all three opponent features together — luminance up, red-green drifting, blue-yellow down — so treating them as independent charges a colour two deviations along that gradient three times over. Measured: sky fifteen rows past the sample scored 11.6 against a threshold of 11.34, so the model refused the very thing it was refining. The fit now carries a full 3x3 covariance, inverted by cofactors rather than by a dependency (D13, the NDK). **Eroded seeds understate the spread, always, in a known direction.** The sample is drawn from the middle of a category and never from its edge, so for anything with a gradient the colours nearest the boundary are exactly the ones left out. The broad mode is therefore fitted wider than its sample by `SHOULDER`. Same pixel: Mahalanobis 5.9 uncorrected, 1.5 corrected — the difference between refusing the horizon and reaching it. Only the broad mode is widened; the tight ones are what discriminate. ## What was given up Strict subtractivity. It bounded the damage and kept `scene.rs`'s partition true for free, and it had to go: a mask that may only shrink can sharpen a horizon inward but never outward, so wherever the coarse contour sat inside the true edge, the error survived every setting of the control. The travel bound replaces it. Everything beyond the ribbon is already a marker, so the flood never reaches it — not "can only remove" but "can only move this far", and the distance is the model's own uncertainty. That single bound also retires the connectivity test, the reachability radius and the separate additive path that an outward-growing rule would have needed. A blue car below the horizon cannot be gained, not because a rule forbids it, but because the flood is never there. `the_colour_gate_only_removes` keeps the older property where it still holds; `the_flood_cannot_travel_further_than_the_ribbon` holds the new one across the whole travel of the control. ## Cost The flood visits only unlabelled pixels, so confining it to the ribbon is not an optimisation added on top — it is what a seeded flood does. A ribbon of a few tens of pixels around one contour is a small part of a proxy. The distance transform is no longer cached, because it has to be measured from the mask as the gate leaves it and the gate moves with the control. That is one transform plus one flood per change of the control, against a precompute that runs the model once. Verified: fmt clean, clippy --workspace -D warnings clean, 63 dr-segment tests.

dtourolle	89c4ff1820	Store what the model found, so a reopened photograph keeps its masks ... A subject or category layer was written to the sidecar as identity alone — which run, which instance, which category — on the reasoning that the pixels are reproducible by running the same model over the same image. They are, but only by *running the model*, and nothing runs one except a photographer pressing "find subjects". So on every path that did not already have a run in memory the layer resolved to no coverage, `MaskPass::render` logged "has no distance field; skipping", and the adjustment was silently absent: - reopening an edited photograph rendered it without its local adjustments, and then saved that state back on the way out; - a batch export from the grid could not have them at any point, because `render_from_library` opens a session, applies a version and renders, and there is no model anywhere on that path. Three hundred files written without the edits their photographer made, over a log warning. Neither failure announced itself. The generated shader still emits the layer's block and the empty placeholder multiplies it by zero, so the result is a well-formed frame that is simply missing an edit — `mask_is_stale` already named the state and called it "not stale, just unrenderable". The coverage now travels in the file, as one `coverage = w h levels payload` line at the end of the layer's block. Two levels, and that is not a compromise. The model hands out a byte per pixel but `Shaped::build` measures its distance field from `coverage >= 128` and throws the shoulder away on the first line; everything soft about the rendered edge comes afterwards from the layer's feather and falloff, which are read off the distance. So one bit per pixel is not an approximation of what the model said — it is exactly the part of it that reaches a pixel, and the stored mask renders the identical frame. Storing all 256 levels would have stored 1.7 MB of bilinear interpolation to reconstruct a predicate, and would not even have compressed: a model mask is a bilinear upsample of a coarse grid, so almost no two adjacent bytes are alike. Measured on a simulated sky and a simulated figure at 1600x1067, against 1.71 MB raw: 4.0 kB and 6.5 kB at two levels, 46 kB and 76 kB at sixteen, 835 kB and 1.43 MB at all 256. The level count is still written into the line, so a later build that finds a use for the shoulder can write sixteen and this one will read them rather than misreading a stream of lengths as pairs. The coder is hand-rolled — run-length pairs in a base-64 varint — because `dr-pipeline` links nothing, which is the property that lets the descriptor and codegen logic be tested without a device. `flate2` would have been fewer lines and a dependency in the one crate that has none. Where it lives matters more than how it is coded. The raster sits on `MaskLayer` beside the source, not inside `MaskSource::Subject`: the source is *identity*, which is what makes it diff as a handful of numbers and merge per field under FR-NC-9, and a raster in there would have given the merge a binary blob to arbitrate. It takes no part in `MaskLayer`'s equality for the same reason — a device that has run the model and one that has not hold the same edit, and counting the difference would raise a conflict over a cache and let `remote_wins` answer it by discarding the only copy of the pixels. Encoding happens in `masks_for_storage`, on the save path, rather than in `ensure_subject_fields` where every coverage already funnels through. `ensure_subject_fields` runs on a drag — dilating a mask with a compound morphology rebuilds the field every frame — and encoding a megapixel raster per frame is the kind of work NFR-P5 exists to keep off a gesture. Saving happens once, when the photograph stops being the open one, and already costs a network round trip. Version skew holds both ways. A file with no `coverage` line reads exactly as it did before, which is a layer that needs the model run; an unreadable one costs the pixels and not the layer, because the layer is the edit and the raster is a cache of it. An old build reading a new file drops the key it does not understand, which costs a model run and no work. And a payload that will not compress is refused rather than truncated: a checkerboard would encode to twice the raster it came from, so past 64 kB nothing is stored and the behaviour falls back to what it was — half a mask would render as a mask that is confidently wrong, which is the failure that tells nobody.	2026-08-30 21:28:54 +02:00
dtourolle	6acc98baad	Carry the photograph's header into an export made from develop ... The same file exported from the library grid kept its camera, its lens, its capture date and its rights statement. Exported from the develop button it kept none of them, and `{date}` in a filename template resolved to nothing at all. Two buttons, one photograph, two different files -- and the develop one was the version the photographer had just finished working on. A session now remembers the header it was opened from, and `open_session` takes that header rather than the orientation read out of it, so a photograph cannot be opened for editing without saying which file it came from. `render_open_frame` clones it onto `Source::Rendered`; both arms of `export_one` -- the worker's own decode and the frame handed over already rendered -- turn a header into a `{date}` and a `SourceMetadata` through the same function, so the two paths cannot come to different readings of one file. What of it actually reaches the exported bytes is still decided inside `dr-export` from the settings, which is what keeps the location-stripping option working here rather than giving it a second implementation to disagree with. The alternative was to hang the metadata on `Source::Rendered` alone and keep it beside the session in the interface. That touches less, but it makes the header and the pixels two cells to hold in step across the six places an image is opened, replaced or fails to open, and the failure mode of getting that pairing wrong is not a missing tag: it is one photograph exported under another's byline and coordinates, silently. Kept on the session, the two travel together or not at all. The header is stored decoded rather than transcribed at open time, deliberately. `dr-export` argues that source metadata is a parameter and not a field on `Frame`, because two exports of one frame may legitimately disclose different amounts; by the same reasoning a session may remember where its pixels came from without that being a decision about what to publish, and the allowlist that decides remains the single function in `export.rs`. A file with no header is left with none -- an empty `{date}` and nothing for the encoder to copy -- rather than today's date standing in for a capture time nobody recorded.	2026-08-30 21:28:31 +02:00
dtourolleandClaude Opus 5	353382c07f	Hand the photographer's place between devices ... A place recorded on the tablet should be where the desktop opens. Exchanged through `.darkroom-derived/place.json`, beside the thumbnail shards and the catalog snapshot. Newest timestamp wins outright: unlike the catalog this is replaced rather than merged, because two devices cannot both be where the photographer is and so there is nothing of theirs inside ours to preserve. It still refuses to upload over a copy it could not read, for a smaller version of the reason `sync_catalog` does: a record we have not compared against may be the newer one, and overwriting it would move the other device's photographer without ever having seen where they were. Last in the pass, and its failures are logged rather than reported. Everything else in that folder is *derived* -- a faster way to learn what the device could work out for itself -- so losing it costs time. A place is a fact only the other device knew, and losing it costs a scroll. A sync that ran out of connectivity should spend what it had on the shards. The full pass runs after a thumbnail sweep or when Sync is pressed, neither of which happens on an ordinary launch -- so a handover would arrive one launch late, which is one too many for a feature whose whole claim is picking up where you stopped. `spawn_place_fetch` is the small half: one GET of a few hundred bytes, started beside the scan. And it can still be refused. A handover is welcome on the way in and unwelcome once the photographer has started: a grid that jumped elsewhere mid-scroll because a round trip finally landed would have lost their place to the feature meant to keep it. Any scroll, scrub, scope change, filter or opened photograph closes the latch, and a record arriving after that is written to disk and takes effect next launch.

dtourolleandClaude Opus 5	d44bffa4a8	Remember where the photographer was ... Opening the application was always a fresh arrival at the beginning of the library, whatever you had been doing when you closed it. What is written down is the view, the scope, the rating filter and the photograph on screen -- the open one in develop, the first visible one in the grid. Not just a scroll position: a position without the filter that produced it names a row of a list that no longer exists. Restoring them has an order for the same reason -- scope, then filter, then position, then the view -- because each step changes what an ordinal *means*. Addressed by remote path and collection UUID, never by an ordinal or a row id. `images.id` and `collections.id` are local to one catalog, and a grid ordinal is local to one ordering; a record naming either would land somewhere arbitrary on a second device and after any filter change on this one. Where the ordinal is needed, `library::ordinal_of_path` computes it through the grid's own `ORDER BY`, taken verbatim by a window function rather than spelled a second time as an inequality -- which is the mistake `grid_order_for` already warns about, and which a manually ordered collection would make unreadable. Every failure degrades rather than reports. A collection this device has not merged leaves the scope at the whole library; a photograph that has since been deleted falls back to when it was taken, which puts the grid in the right week; a torn file yields no place and the library opens at the top. Reopening develop is the one thing that requires an exact match, because a canvas on a path that no longer resolves is a filename over an empty frame. The record lives in `dr-types` beside `Settings` and the store lives here beside `SettingsStore`, for the reason `dr-types`' manifest gives: a JSON serialiser in `core/` would be paid for by every crate there. Two files and two lifetimes, though -- resetting preferences must not forget where you were. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-30 20:39:50 +02:00
dtourolleandClaude Opus 5	8bf5e13faf	Centre the photo roll on the frame it opens with ... The roll brought the open photograph into view by the shortest move, which is right for stepping along it and wrong for the first look: a frame near either end of the loaded window arrived hard against an edge, with nothing on that side to give it any context. It now centres on the first settle of a develop session and steps minimally after that. A one-shot request that the strip itself clears -- the only thing that knows the request has been honoured is the code honouring it -- rather than something recomputed on creation, because the strip is created far more often than a session begins: leaving develop for Settings and coming back rebuilds it, and re-centring then would undo a roll the user had scrolled by hand. Raised on the two ways into develop from the grid, and not on a pick along the roll, which is a step within a session rather than the start of one. Centring is clamped to the ends: the third photograph of a window cannot be centred without scrolling empty space in beside it, and a strip that begins with a gap reads as broken rather than as centred.

dtourolleandClaude Opus 5	0ff1e01ec3	Come back from develop on the photograph you were editing ... Leaving develop returned to where the *grid* was, which after a walk along the photo roll can be a thousand rows from the frame you had just finished. So the one photograph you were certainly interested in was the one the grid came back without. Two positions, and the rule is not to pick one of them. The grid seeks to the remembered position, then reveals the keyboard cursor -- which is now put on the open photograph, and which moves the viewport as little as will bring its row into view. A frame inside the remembered screenful moves nothing at all; one outside it scrolls exactly far enough. One rule, both behaviours. The cursor rather than the selection, deliberately: `place_cursor` also rewrites the selection, and a set of forty photographs assembled in the grid must survive having one of them opened. `reveal()` now also runs on the grid's `init`, since `cursor-row` is initialised rather than changed when the subtree is rebuilt and no handler would otherwise fire. Both it and the roll's centring defer while the element has no height yet -- `init` runs before layout, where a height of zero makes every row look off screen -- and a latch brings the first real height back to the cursor without letting every later resize haul the viewport around. The capture-time marker follows the same move, for the same reason: `load_window` rebuilds the axis only when the scope, the filter or the total has changed, and none of them has. It is the same library seen from a different row. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-30 20:35:23 +02:00
dtourolleandClaude Opus 5	53dc2d171e	Say where the grid is on the capture-time axis from the first frame ... The sidebar's marker rested greyed at mid-track until the first scroll or scrub. The reasoning was that anchoring it would imply a choice the user had not made -- but that reads the marker as reporting an intention, and it does not. The sidebar's whole claim is to say *when* you are, and that is known from the first frame: the grid is at the top of the library, or wherever it was last left. So a launch opened with the marker halfway down an axis whose visible photographs were all from the wrong end of it. Dimmed rather than absent, which made it look like a reading rather than the absence of one. Seeded in `refresh_timeline` -- the one place that decides what the marker says, and the one that runs on every route which builds the axis -- and only when nothing has claimed it, so a scroll or a scrub still speaks for itself.

dtourolleandClaude Opus 5	eed27eb36d	Keep the grid's place when another screen covers it ... Opening Settings, Import or People and coming back landed at the top of the library however deep in it you had been. The grid is gated on an `if` in the markup, so every route away from it destroys the subtree and rebuilds it. A Flickable being destroyed passes its viewport through zero on the way out, and that reaches `on_library_scrolled` looking exactly like the user having flung the grid to the top. The handler already guarded against it -- but on `show-library`, which means "the library rather than develop" and stays true while any of those four screens replaces the window. So the guard covered the develop route and none of the other three: `resume_at` was overwritten with 0 on the way out, and the position was gone before anything could restore it. The condition the `if` is actually spelled with is now computed once, in `app.slint`, and Rust reads that. The two cannot drift apart again because there is only one of them. That fixes the overwrite. The second half is that nothing replayed the position on the way back in: `on_back_to_library` does it by hand, and Settings, Import, People and the launch screen do not go through it. Rather than teaching three more modules to call it, `scroll-to` is now kept current on every scroll. It is read by `seek()`, which runs on a token change and on `init`, so writing it without bumping the token cannot move the grid on screen -- and is exactly what the next grid reads when it is built.

dtourolleandClaude Opus 5	4dc954f01a	Take the photo roll's grab band off the buttons that end a mode ... "Done Cropping", "Done Repairing", "Done Masking" and "Fit" float over the foot of the canvas. So does the photo roll's swipe handler, and a gesture handler is not a layout box — it is an input surface. A press inside one is delayed, then offered to that handler's own children and to nothing else: `input_event_filter_before_children` returns `DelayForwarding`, which aborts the hit-test traversal outright, and the replay afterwards visits only the handler's subtree. Everything behind it is never asked, hover included. The band was `strip-height + reach` — 136px along the bottom — whether the roll was out or away. So the button that ends a mode was drawn, was lit, and did nothing for as long as a library was open, which is the whole time anybody is developing from one. The tool rail kept working because it is a sibling of the canvas rather than behind the roll, which is exactly why this looked like two dead buttons rather than a dead region. The band now goes where the roll goes. The handler carries the strip instead of standing still while the strip animates inside it: closed, only `reach` is on screen and the rest hangs below the window where nothing can press it; open, it still covers the thumbnails, which is what lets a swipe down anywhere across them put the roll away. The 180ms travel moved from the strip onto the handler, so the drawn positions in both states are what they were. The controls are then positioned against that band rather than against the bottom of the canvas, and ride up with the strip when it comes out. Reordering them in front of the roll would have been the other fix, and it is the wrong one — the band would become the thing that cannot be reached, and a gesture nobody can start is worse than a button with a second way out. `roll-strip` and `roll-reach` are tokens now, because two files have to agree on where that band is for either of them to keep out of it. The bottom of the photograph comes back with it: the crop's lower handles and a repair placed near the bottom edge were inside the same 136px and had the same fault.

dtourolleandClaude Opus 5	3d248cfb79	Export the photograph, not the canvas ... Zooming the develop view changed the exported file. `Framing::view` is kept out of the sidecar, out of `is_active` and out of `output_size` precisely so that it cannot — but those exclusions keep it out of the *edit*, and an export is a *render*. `visible_rect` deliberately folds the view into the single rect the fused shader's prologue samples, so `render_for_export` inherited it: at 4:1 it wrote the middle of the frame, magnified to fill the file at the full output size, with the detail kernels scaled four times over because `render_scale` folds the view in as well. `render_thumbnail` did the same to the grid. `render_uncropped` already suspends the view for this exact reason, so the fix is its pattern: one `render_the_file` that both file-producing paths go through, composing inside the suspension since the view reaches the shader as a uniform baked at composition time. Restored whatever happens — leaving the graph un-zoomed after a failed export would throw away where the photographer was looking. Nothing caught it because the guard checked the wrong things. `zooming_does_not_change_the_exported_image` asserted the output size and the crop; both held perfectly throughout. Renamed to `zooming_does_not_change_the_size_or_the_crop`, which is what it tests, and the pixels are now guarded where pixels exist. The new test uses a ramp rather than quadrants deliberately: a four-quadrant frame is self-similar under a centred zoom, and the first version of this test passed against the bug because of it. Traces FR-EXP-9, which asks for the full-quality pipeline "regardless of what the display was showing". Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-30 19:41:30 +02:00
dtourolleandClaude Opus 5	a1e361e35a	Measure the native path against the one it replaces ... Everything argued for this change so far was read out of a catalog after the fact: crop_px across 18,671 faces the old code had already stored. That is evidence about what the previous implementation did. It is not evidence that the new one does better, and the difference matters because a landmark left in the detector's coordinates, or a box filter with an off-by-one in its source span, would both produce faces that look entirely plausible until somebody counted the pixels behind them. So examples/face_native.rs renders one file and indexes it twice, native and from a 1024 proxy, changing nothing else. Fourteen originals from the reference library, 5472x3648 CR2 and DNG: native 9 faces, mean crop 287px 1024 proxy 5 faces, mean crop 75px Crops 3.8x larger, and across the line that decides whether the crop is photographed or interpolated: 75px is below ALIGNED_EDGE, so the proxy path was upsampling into the embedder on average where this one downsamples into it. Fourteen images and nine faces is enough to show a direction and to catch a wrong scaling; §7b says so rather than quoting the ratio as a library-wide figure. It also corrects something §7b asserted two commits ago. I wrote that detector input resolution cannot affect recall, because §4.1 letterboxes everything to 640. Native found nine faces to the proxy's five, including four on files where the proxy found none, so it plainly can. The two paths differ in their resampling as well as their size, and this experiment does not separate those, so §7b now records the result as evidence for the double-resampling hypothesis rather than as its proof. M4 still owns settling it. The audit-summary test went stale when the ready/to-fetch split was collapsed and is updated to assert the single number, including that the old wording is gone.

dtourolleandClaude Opus 5	4af3b93dfa	Index faces from the native render, not from a preview of it ... Implements the FR-CULL-8 written two commits ago. The sweep fetched the JPEG preview embedded in each RAW and used that one buffer for both detection and the crop; it now fetches the original, renders it through the same path export uses, reduces that for the detector, and warps the crop back out of the native frame. Three pieces, and each exists for a reason worth stating. dr_face::Pixels lets the warp sample 8-bit RGBA directly. A 24 MP native frame is 96 MB as RGBA and 288 MB converted to the f32 RGB align.rs was written against, and the warp reads about forty thousand pixels out of it. Converting the whole frame to sample 0.2% of it is NFR-RES-2's budget spent on a copy, per image, for a whole library. The variant costs one branch per sample and a test asserts both layouts produce identical crops. The detector gets a box-filtered reduction to 1600px, not the native frame and not a point-sampled one. Averaging rather than sampling because the detector's job is finding small faces and decimation is precisely the operation that removes them: at 4x, fifteen of every sixteen pixels are discarded and a 40px face survives or not depending on where it falls relative to the sample grid. 1600 rather than 640 leaves the letterbox a mild 2.5x rather than a 9x, and bounds the f32 buffer at 20 MB. Landmarks come back in the reduction's coordinates and are scaled to native in one place before any crop pixel is read. This is the failure mode that would not announce itself -- unscaled landmarks put every crop near the top-left corner, which yields faces of something else, cleanly embedded and confidently clustered. The sweep fetches SWEEP_LANES-wide and renders sequentially. Not a placeholder for a parallel version: there is one GPU, so concurrent renders queue on it regardless, and each materialises a native frame. Overlapping them would multiply the one allocation that threatens the memory budget while buying parallelism that does not exist. The chunk drops from 96 to 6 for the same reason -- 96 held 8 MB previews, this holds whole RAWs. The stored edit is deliberately not applied, which is where this departs from export::render_from_library. Face geometry is normalised to the frame, so indexing a cropped render would record boxes against a frame that changes whenever the user changes their mind, and every stored box would quietly become wrong. Orientation is applied: that is a fact about the file rather than an edit. examples/face_native.rs renders one file and indexes it both ways, so the claim behind all of this can be checked against photographs rather than re-read out of the catalog it came from.

dtourolleandClaude Opus 5	9ddc1273c0	Make a sweep that fails everything say so ... A run over 169 images failed all 169, in fourteen seconds, and reported "0 face(s) in 0 image(s)" -- the same sentence a run that indexed nothing because there was nothing to index produces. Three separate places dropped the information on its way to the screen. The progress count only moved on success. FaceSweepMessage had no failure variant at all, so a pass where every image failed sat at 0/169 from the first tick to the last: the receiver was told the total, told nothing, and told the pass had ended. That is indistinguishable from a hung job, and it is what it was taken for. Finished already carried a failed count and identity_ui matched it with `Finished { .. }`, throwing the number away and printing the tidy success line regardless. And the reason each image failed was logged at debug, which is off, so 169 consecutive failures left no trace of why anywhere. Failed { images } now carries the count back per lane batch, the progress counter advances on it, and both the running status line and the finishing activity row say how many could not be read. A batch rather than one message per image because failures come back lane-sized and the useful number is how many. Also renames the store sweep's guard to MIN_CROP_EDGE with the rest of that constant's move, since the two touch the same lines.

dtourolleandClaude Opus 5	e7b526c550	Specify face indexing at native resolution, and say what the proxy cost ... FR-CULL-8 said detection runs against the thumbnail or proxy tier and never a full decode, and faces.md §5 said the aligned crop is sampled from that same proxy. Both are wrong in the same place: they treat detection and cropping as one resolution problem when they are two, with opposite answers. Detection does not care. §4.1 fixes the graph's input at 640x640 and letterboxes whatever arrives, so a face filling 2% of the frame reaches the model at 12px whether the buffer handed over is 1024px or 6000px. Every pixel above the detector's own input is discarded before inference. The crop cares about nothing else. §5's warp produces the fixed 112x112 ArcFace sees, so source resolution converts directly into whether those 112 pixels were photographed or interpolated. Reading crop_px across the 18,671 faces the proxy-tier implementation stored: 47.3% were upsampled to reach the embedder, 314 of them by more than 2x, the smallest from 34 source pixels. An upsampled crop does not fail loudly -- it yields a confident embedding of detail that was never there, and the damage appears three stages later as clusters that will not separate. So FR-CULL-8 now specifies four stages with the resolutions named separately: render native through FR-EXP-9's pipeline, downscale for the detector, map boxes and landmarks back to native, crop and align from the native render. The affordability the old rule bought is met instead by when the pass runs -- background, preempted, resumable -- and the requirement says plainly what it now costs on a remote library: the original rather than FR-NC-3's byte range, 412 GB across the reference library's 19,107 images, so a whole-library pass is a transfer under FR-NC-6 rather than something that may start on its own. MIN_CROP_EDGE replaces the MIN_DETECT_EDGE this branch briefly had. Same number, guarding the quantity that turned out to matter. faces.md §7b records both measurements, and marks the second as unexplained rather than dressing it as a finding. Grouped by the buffer detection ran against, faces per image was 0.078 at 1024 or below and 1.82 at 2048 or better, controlled for file type and size. That gap is real and reproducible and I cannot account for it, because the letterbox above says detector input should not matter. M4 is where it gets settled. The crop measurement does not depend on it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-30 19:41:20 +02:00
dtourolleandClaude Opus 5	144d2e4e84	Revert the detection floor: it guards the wrong resolution ... Reverts 53f7cdf and e92d22d. The floor those added sat on Detector::detect, refusing any buffer under 1025px on the reasoning that a small buffer finds no faces. That reasoning does not survive §4.1: the detector letterboxes every input to 640x640, so a face occupying 2% of the frame presents at 12px to the model whether it is handed a 1024px buffer or a 6000px one. Detector input is precisely the quantity that does not matter. Worse than merely useless, it blocks the design FR-CULL-8 now specifies, where the detector is deliberately fed a downscale and the crop is taken from the native render. A guard on detect() rejects exactly that call. What the measurement actually supports is a floor on the *crop* source, which is where resolution converts into embedding quality, and which faces.crop_px already records: 47% of the reference library's faces were upsampled to reach 112x112. That floor is a separate change against the native-resolution path and does not belong on the detector. The 23x faces-per-image gap by source_edge that motivated the original commit is kept in faces.md §7b, restated as the unexplained observation it is rather than the causal claim it was written as. V12 stands: those runs cropped at 1024 whatever detection did, and that is reason enough to look at them again.

dtourolleandClaude Opus 5	41c655c176	Stop the local-store pass pretending it can still index ... spawn_store_face_sweep detects on what the thumbnail store holds, and the store's largest tier is FACE_TIER -- 1024, which the floor now refuses. Left alone it would list every outstanding image, decode every proxy it had, and report every single one as failed: twenty thousand refusals all saying the same thing, with the real explanation buried at debug level. There is no repair available inside this pass. It has no larger tier to read; the pixels the detector needs have to come off the server, which is spawn_face_sweep's job and always was. So the honest behaviour is to check the tier against the floor once, say plainly which pass to use instead, and stop. It is only reached from examples/face_index.rs, so this costs the tool its --run mode and no shipped behaviour. FACE_TIER keeps its value and loses its meaning. It is now the tier a stored crop is *cut from*, which 1024 is entirely adequate for -- the face has already been located and the crop only has to be looked at -- and no longer the tier faces are *found* on, which is the thing that was returning 0.078 faces per image. IndexAudit's ready/awaiting_proxy split goes the same way. It existed because one of the two passes could only do images that already had a proxy; now that detection refuses that proxy's size, both halves cost the same fetch, and a status line reading "169 ready to index" implies a distinction that no longer decides anything. One number. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-30 19:41:04 +02:00
dtourolleandClaude Opus 5	d0ebc9f571	Count the same images in the progress figure that the sweeps index ... The Identity screen said 4,593 images were left to index and stayed there for hours across repeated runs, which is what a stuck job looks like. It was not stuck. 4,424 of those 4,593 are shadowed -- the JPEG half of a RAW+JPEG pair -- and no sweep will ever index one, because every work list is built on VISIBLE, which excludes them. They are not separate photographs and the grid does not show them either. But faces::coverage counted them: its denominator was "images WHERE trashed_at IS NULL", with no shadowed_by clause. So the outstanding figure had a floor of 4,424 that no amount of work could bring down, and Coverage::is_complete could never once return true no matter how completely the library had been indexed. A progress number that cannot reach its own target is worse than no progress number. The fix is to count the population the sweeps actually draw from, in all three places that were describing it differently: coverage's denominator and its indexed join, and audit's split of the outstanding set, which had the same gap and fed the same status line. On the reference library the denominator goes from 23,531 to 19,107 and outstanding from 4,593 to 169 -- the second of which is a number the user can watch go down, and which turns out to be a real and separate fetch failure worth chasing.

dtourolleandClaude Opus 5	6783d0c723	Settle the images whose best preview is under the floor ... The floor introduces a state the sweep had no arm for. An image whose largest embedded preview is genuinely smaller than 1025px now comes back from index_preview as an error, lands in the generic Err arm, and is counted as failed -- which means no face_index row, which means it is still outstanding, which means the next sweep fetches exactly the same bytes and refuses them again. For ever, on every run, at one range request each. The previous behaviour was wrong but at least terminated; this would not. So ProxyTooSmall gets its own arm, and it records a marker at the true edge rather than nothing. That is the difference between "we looked and found nothing" -- which would be a lie, since nothing was looked at -- and "this was examined at 900px, which is the best this file has". The first is unrecoverable; the second is a fact source_edge was added to carry, and a later floor or a bigger proxy can select on it deliberately the way V12 just did. Counted separately from failures all the way up, because they are not failures and reading them as such would misdescribe a library of small scans as a broken network. The summary line says how many and why. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-30 19:41:04 +02:00
dtourolleandClaude Opus 5	0a6509de93	Forget the face runs made on proxies too small to see a face ... The floor added in the previous commit stops this happening again; it does nothing about the 1,824 images in the reference library that already carry a face_index row written against a proxy of 1024 or less. Those rows are why the damage is permanent rather than merely past. The work list is "images with no row for this model", so an image examined against a 1024px proxy -- 0.078 faces per image, nine in ten finding nothing -- is indistinguishable from one examined properly, and no later pass will ever offer it to the detector again. V12 deletes exactly those markers, and nothing else. The faces those runs did find stay in place and keep drawing the People screen until a better pass replaces them, and record_detections re-attaches the user's confirmed names across that replacement by box overlap, so a library somebody has spent an evening naming does not lose that evening. The cost is a re-fetch of the affected images. Deleting the marker rather than teaching the work-list query to select on source_edge, which was the other option and is worse. A standing `source_edge < floor` predicate never lets go: an image whose largest embedded preview is genuinely smaller than the floor would be re-fetched on every sweep for ever, because the next pass cannot do any better than the last one did. A one-off deletion gives each affected image exactly one more attempt through the good path and then lets the ordinary "has a row" rule settle it. The threshold is written out in the SQL instead of referring to dr_face::MIN_DETECT_EDGE. A migration has to keep meaning what it meant when it ran; binding it to a constant someone may raise later would quietly change what an old catalog gets migrated to.

dtourolleandClaude Opus 5	1d800d56b0	Refuse to detect faces on a proxy too small to find one ... Detection was run on whatever proxy the caller happened to have. A small one does not fail -- the image is letterboxed into the detector's 640px input at any size -- so it comes back with almost nothing, and the caller then writes a face_index row saying the photograph was examined. That row is the damage. Nothing distinguishes it from "examined properly, no faces in this one", so the image is never looked at again. The measurement, on the reference library of 23,531 images. Runs against a 1024-edge proxy: 0.078 faces per image, 90% of them finding nothing at all. Runs against 2048 or better: 1.82. To rule out the obvious objection that small proxies just come from small photographs, the same comparison restricted to DNGs -- 1,592 of them averaging 21 MB against 7,724 averaging 23 MB, so the same kind of file in the same library -- gives 0.078 against 1.82 again. Twenty-three fold, on identical source material, identical weights, identical options. So the floor goes in the detector rather than in either sweep, because both of them, the example tool and any future job handler are equally entitled to get this wrong, and there is one place that sees every attempt. It is 1025, not 1024, and the odd-looking number is the point: 1024 is exactly ThumbSize::Large, the tier proxies are stored at and the tier one of the two sweeps was detecting on. A floor that admitted 1024 would admit precisely the population this exists to exclude. Written as a minimum rather than a maximum so the test at each call site is `edge < MIN_DETECT_EDGE` with no boundary left to get wrong. ProxyTooSmall is its own error variant rather than an empty result because the caller has to tell it apart from a failure: nothing is wrong with the image or the model, and the answer is to go and find better pixels, not to retry these ones.

dtourolleandClaude Opus 5	7981718d83	Time the phases of a launch, because the tablet has no profiler ... Two things are now off the launch path and the rest of it is unmeasured. There is no way to attach a profiler to an Android launch, and the window that matters — from `android_main` to the first `poll_events` — is over before anything on the device can be asked a question about it. So a line in the log file is the only measurement anybody gets. Three of them: the GPU open, the window build, and the total to the event loop. The last is the one that matters, because it is the figure the input dispatcher is counting against — anything approaching five seconds there is the next ANR whatever the phases above it say. The GPU open is timed rather than moved. It is a Vulkan instance, an adapter enumeration and a device request, and on the desktop it cannot be deferred at all: it selects the Slint backend, and creating a window selects one for us. On Android it could be, because nothing shares that device with the compositor (TD-1) — but "could be deferred" is not "costs enough to be worth deferring", and there is no number yet that says which. This is the line that will produce one. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-30 18:41:34 +02:00
dtourolleandClaude Opus 5	d48e9f6033	Open the catalog on a worker, so a launch is not a page-by-page read ... The second thing standing between `android_main` and the first `poll_events`, and the one that grows with the library rather than with the APK. `library_ui::open` called `show_catalog_now`, which called `Catalog::open_verified`. That runs `PRAGMA quick_check`, which reads every page of the database, and then `Catalog::open`, which takes a full SQLite backup of the file before a migration and rewrites its structure afterwards. On a 50,000-image library that is tens of megabytes of I/O on a tablet's flash, and it happened before the window had painted anything — so on Android it was counted against the five seconds the input dispatcher allows, and on the desktop it was a launch that sat on a blank window. `dr_catalog::recovery`'s own module documentation says the check is affordable "at startup, where a failure has a user in front of it who can answer a question". That was the intent and it was not true: there was no interface yet in which to ask. Now there is, because the open happens on a worker and the answer arrives on a channel drained by a timer — the same shape the scan, the thumbnails and the login already use. The gate the synchronous call provided is kept, and is the reason the scan moved with it. `Catalog::open` succeeds on a damaged file whose header survived, so a scan running beside an unanswered recovery question writes ETags and image rows into damaged pages and turns a catalog that had a backup into one where the backup is the only copy left. So the scan now starts from the drain, on the two answers that permit it, and not at all on `Corrupt`. `library-scanning` stays true throughout, which hides the Rescan button and stops the gate being merely advisory. What the user sees while it runs is a third empty state. The grid already refused to conflate "still scanning" with "scanned, found nothing"; "opening the library" is a third answer and it gets its own sentence, because a grid saying "Scanning…" while nothing is on the network is the same kind of lie the other two were separated to avoid. `show_catalog_now` stays, unchanged and blocking, for `recovery_ui`. That call site has the event loop running, has just replaced the file under a `forget_catalog`, and has `recovery-busy` on screen — the same reasoning `recovery_ui::answer` already gives for doing its file copy in place. The part both paths share is now `adopt_catalog`. One consequence worth naming: the cache-usage figure on the settings page was read at startup from a catalog that is no longer open by then. It moves to the page's `on_open` closure, beside the face coverage, which is read there for exactly the same reason — it is only ever looked at while that page is on screen.

dtourolleandClaude Opus 5	1c5849ebe8	Unpack the bundled models on a worker, not on the way to the first frame ... Launching v0.10.0 on the tablet produces an ANR: "Waited 5000ms for MotionEvent", 5,827 ms on one input sequence, over a window that has never painted. The app recovers and sits at 0% afterwards, so it is a startup cost rather than a hang. The structural fact behind it is that `android_main` runs with the activity's input channel unserviced. Nothing drains it until Slint reaches `poll_events`, and Slint does not reach `poll_events` until `dr_ui::run` calls `window.run()` on its last line. Every millisecond before that is a millisecond the input dispatcher waits on, so five thousand of them is an ANR whatever the work happens to be. The largest single piece of that work was here. `install_bundled_models` copies 41 MB on the first launch after an install — 24.9 MB of scene model, 13.6 MB of embedder, 2.5 MB of detector — each read whole out of the APK into a `Vec` and written to `/data`, in a loop, on that thread. v0.10.0 is the release that added the scene model, which is 60% of that total, and it is the release the ANR appeared in. The 8,010 minor faults in the report are about what 41 MB of freshly touched pages costs. So it moves to a detached thread and the function returns as soon as the thread is running. Nothing on the launch path wanted the result: the only two things that read these files are the People screen and the scene tab, both of which are reached by hand, minutes later, from workers of their own. What that costs is a window in which a model looks absent. `library::face_models` and `library::scene_model` decide availability on `is_file()`, so during the copy both report their feature unavailable — which is the same answer they give a build shipping no weights at all, the ordinary case both were written around. Briefly pessimistic rather than wrong, and the temporary-name-then-rename that was already there is what keeps it from being worse than that: a lookup never sees a half-written file, only an absent one. Both call sites now say so. A completion line reports the bytes copied and the milliseconds taken, including when it is zero, so the second launch after an install can be told from the first in a log rather than by inference.

dtourolleandClaude Opus 5	4efab496c2	Put the refinement on a slider, per layer ... The evidence was being gathered and spent immediately at one strictness nobody could see or change. This makes it a control. `MaskLayer::refine` is shaping, like the feather, and it lives on the layer for the layer's reason: two layers may sit on the same category and want different amounts of it, and the model ran once for both. ## What the segmentation now stores `CategorySummary` keeps the **coarse** mask and the `Refinement` beside it, rather than a refined mask. That is what gives the control an off position that is bit-for-bit the model's own weighting, and what stops a strictness change from needing the model again. `category_mask_at` borrows at zero and wherever no refinement could be fitted, so a layer nobody has touched costs nothing over the old path. The fit moved to the far side of the orientation permutation. The verdict is a per-pixel field over the same grid as the mask it gates, so fitting it upright would mean permuting a proxy-sized buffer afterwards to match — a second rotation, and a second chance to get one wrong. One logit cell is the same number of pixels either way: the letterbox scales by the longer edge and a permutation does not change which edge that is. The two frames became a `Frames` struct rather than six parameters. This function reads the picture twice for opposite purposes — the model needs it upright or it recognises far less, the refinement needs the sensor's grid — and a transposed pair produces a plausible mask over slightly the wrong pixels, which is the failure this module is most prone to. ## It rebuilds the field, and the signature says so `refine` is mixed into `subject_signature`. Unlike a feather, which is read off a field that is already correct, this changes which pixels are in the mask at all — so it changes the coverage the field is measured from. Omitting it is the bug where the slider moves and nothing happens until some unrelated control invalidates the cache. That puts it in the same cost class as a close or an open, which is why the row takes `SliderRow::changed` — already once-per-gesture, since that row takes `SliderTrack`'s `committed` internally — rather than a live stream. The slider is offered only where there is something to move: a category source, *and* a refinement the frame actually gave enough to fit. A control that moves and does nothing is worse than an absent one. ## Two defaults that are deliberately different A layer added from the panel starts at 4.0, because a category's edges are twenty proxy pixels wide before anything is done to them and a photographer adding a sky mask wants the sky rather than the sky plus every chimney in it. A layer read from a sidecar with no `refine` key starts at **zero**. A file written before this control existed has to render as it did then, and a default of 4 on absence would quietly re-grade every stored category mask in the catalogue. `a_categorys_refine_strictness_survives_and_defaults_off` holds both halves, and `an_out_of_range_refine_is_clamped` holds the file to the scale — past the top of it every colour fails and the mask deletes itself, which reads as lost work rather than as a bad file. `MAX_REFINE` is dr-pipeline's own constant mirroring `dr_segment::STRICTNESS_MAX`, following `Falloff` and `Morphology`: this crate holds the description of an edit and must not depend on the crate that runs a model. dr-ui is where the two meet, and the only place that converts.

dtourolleandClaude Opus 5	f87bf6ebc0	Charge a colour mode for its rarity, and keep the verdict ... The refinement worked and could not be controlled. Pruning modes below a share threshold made the flag's removal a *discrete* event: below the line its Mahalanobis distance was enormous and nothing rescued it, above the line it sat at zero and nothing removed it. A control over that would appear dead through most of its travel and then start eating sky. So the prune is gone. A mode is charged `−ln(share × k)` nats, floored at zero, and that cost enters both tests — doubled in the chi-square, which is a squared distance, and directly in the log density. Rarity becomes a distance rather than a threshold, and the things a photographer wants to remove separate along it. Measured on the synthetic frame the tests build: a flag holding 1.6% of the sky is more than half gone by **2.95 nats** and a cloud bank holding a third of it survives to **5.75**. The whole interval between them is somewhere a control can sit. `the_flag_goes_before_the_cloud_does` pins the ordering, which is the property that makes one slider worth offering at all. Measured against an even split rather than against one, so raising `clusters` describes a category more finely without making every colour in it look rarer. Floored at zero so a dominant mode earns no *discount* — a bonus there would let the commonest colour outvote a bad chi-square, which is the one direction this must not bend. `Refinement` holds the per-pixel verdict, quantised to a byte over ±16 nats — an eighth of a nat per step, far finer than the narrowest transition the gate can be asked for, and the same size as the coverage buffer it sits beside. `apply` is then a smoothstep, and the model is never consulted again. That is `distance.rs`'s arrangement deliberately: there a signed distance field is computed once and feather, grow and shrink become arithmetic on it, "which is what makes those live controls rather than ones that stall on every drag". Same shape, different field. The blur moved with it, from the gate to the verdict. Smoothing the evidence rather than the decision means it is paid for once in `compute` instead of on every frame of a drag, and it is the better thing to smooth in any case. `apply` at `STRICTNESS_OFF` returns the weights untouched without reading the verdict at all. A control whose off position is *very nearly* the unrefined mask cannot answer "is this helping"; one whose off position is the unrefined mask can. `strictness_zero_changes_nothing` holds it to that, and `strictness_is_monotonic` holds the rest of the travel to only ever removing more — a slider that gave weight back partway up would be one whose direction nobody could predict. The synthetic sky is smooth enough to sit on `VARIANCE_FLOOR`, where a real one has noise and therefore a real spread, which moves every crossing down together. The ordering survives that; the placement is a calibration. Which is the honest argument for a control rather than a constant, and why the default sits at half scale instead of at the flag's measured crossing. The example sweeps the whole range and writes a frame per nat, because the question a photographer asks of a slider is where to put it, and that needs the travel rather than a point on it.

dtourolleandClaude Opus 5	4f4abd335f	Cut a scene category back to the pixels that agree with it ... A flag in the sky came out weighted as sky, and no feather setting fixed it. The scene model's logits are `[1, 150, 80, 80]`, so one cell is eight input pixels; at the 1600px proxy the letterbox scale is 0.4 and **one cell is 20 proxy pixels**, which `rasterise`'s bilinear then spreads across one more either side. A flag is a handful of cells whose softmax is dominated by the sky around it. The information was never in the grid, so nothing downstream of the grid can recover it. Tiling is the answer for an instance and is not available here: a category has no bounding box to tile over — sky is wherever the sky is. But the photograph is at full proxy resolution even though the weights are not, and it knows exactly where the flag is. So the model says *what*, and the pixels say *which of them*, which is the division of labour arm C already draws between the instance model and the watershed. ## Seeds, and why the erosion radius is not a guess Threshold the weights high, take `signed_distance`, and keep what is more than 1.5 cells inside. One cell *is* the model's resolution and the bilinear spreads it across one more, so the band either side of the boundary is smear rather than evidence. Deriving the radius from `Scene::cell_pixels` rather than picking a pixel count means it stays right if the proxy edge or the export changes. The mirror of that set is a confident *exterior*, free from the same field. ## Dropping small modes is the step that makes it work Four k-means modes per side, not one Gaussian: sky is blue at the zenith, white where the cloud is and pale at the horizon, and one blob over all three rejects two of them. Then modes holding under 3% of a side are discarded, and without that step the whole thing fails on the case it was built for. A small flag deep in the sky has both a high weight and a large distance from the boundary, so it lands in the interior sample and teaches the model its own colour. It cannot be excluded geometrically. It can be excluded by share. Luminance is weighted at a quarter against chrominance for the same reason the watershed's gradient is. Sky's variance is dominated by luminance, so at equal weight the distribution is a long bright streak that a mid-grey flag sits comfortably inside. A flag is separated by chrominance; a cloud is separated by luminance alone. Not zero, or a dark bird against a bright sky survives. ## Two tests, because either alone is wrong Absolute — is this colour plausible under the category, as a chi-square on the Mahalanobis distance. Comparative — is it likelier inside than outside. A pixel must pass both. The absolute test is what catches the flag, whose colour is far from *both* sides and which the comparative test alone would leave at even odds. The comparative test is what stops the absolute one needing a constant tuned per category. ## What this cannot do, written down rather than left to be discovered An intruder large enough to hold its own mode is kept. By share, a flag over a fifth of the sky and a cloud bank over a fifth of the sky are the same object, and colour does not separate them either — a white cloud is as far from blue sky in chrominance as many intruders are. So `min_cluster` is not a threshold with a correct value waiting to be found; it is the trade-off itself, set where a photographic intruder falls. Both ends are pinned by tests — `a_flag_in_the_sky_is_removed` and `an_intruder_larger_than_min_cluster_survives` — so that moving the number reads as moving the trade-off rather than as fixing a bug. The case left open is a large unrecognised object in a clean category, which wants the boundary snapped to watershed basins and is a different mechanism. ## Safe to apply without a control It is subtractive: the output is the input times a factor in `0..=1`. The worst failure available to it is losing part of a real sky, never gaining a region, so a blue car below the horizon that was never in the mask cannot be pulled into it. And a factor in `0..=1` cannot raise a sum, so `scene.rs`'s partition still holds when every category is refined independently — the weight taken off the flag lands in the unlisted remainder, which is where a flag belongs, ADE20K having no class for one. Every path without the evidence to judge returns the weights untouched and says which path it took. A refinement that silently did nothing is indistinguishable from the feature being off, and an empty seed set fitted to a distribution would reject every pixel. The signature is deliberately unchanged: categories are addressed by name, not by index, so a sharper mask cannot create the stale-index hazard the signature exists to guard against. The example writes `<prefix>-<category>-refined.ppm` beside the coarse one, never instead of it — whether this is an improvement is a comparative judgement and one image cannot answer it.

dtourolleandClaude Opus 5	bfdb6d5e4b	Cut the People rail's portraits off the blocking path ... Opening Identity cut a portrait for every person before the screen was allowed to appear. Measured against the reference library: 3.6 seconds, of which 3.2 is 931 full 1024px proxy decodes — the fallback for faces indexed before crops were stored beside them. The rest of the wait was the rail building 14,268 rows, fixed in the commit before this. `refresh` now draws with the portraits already cached and hands the rest to `fill_covers`, which cuts them 8ms at a time — under half a frame — behind a screen that is already up. Blocking work on that path goes from 4,965ms to 16ms on this library. A timer rather than a thread. The work is a catalog query and a decode against a `ThumbStore`, and both handles live on the UI thread; a worker would need its own connection to the same file, which is what the sweep and the regrouping pass do because they run for minutes and would otherwise be unbounded. This is seconds of small, independent pieces, so slicing answers the same question more cheaply. `pending` is in rail order, and the rail is sorted by confirmed faces, so the portraits the user is looking at are cut first. It patches single rows rather than reloading: a reload would rebuild the model on every tick, and a model replaced underneath the `ListView` is what the slicing exists to avoid. Each patch checks the row still holds the person it was started for — a stale index would draw a face beside somebody else's name — and stops the fill when it does not.

dtourolleandClaude Opus 5	d7b851f622	Build the People rail rows you can see, not the ones you cannot ... `Flickable { VerticalLayout { for ... } }` instantiates every row. On the reference library that is 14,268 row subtrees, which measures at 4.2 seconds before a pixel is drawn — and it was paid again on every action, because every action reloads the model. Roughly half the wait between clicking "Identity" and the screen appearing was this. Slint's compiler has a virtualising path for a `for`; it is what makes `std-widgets`' `ListView` cheap. It keys on the parent element's base being *named* `ListView` and exposing the five lengths its layouting code writes back, and a custom base is explicitly allowed. So `widgets.slint` grows one, and `std-widgets` stays out of the file that establishes our style. Measured on the real screen: 200,000 rail rows now render in 62ms. Three things had to be true together, and each was silent on its own. **The row height must be constant.** The rail hid a set-aside person with `height: cond ? 52px : 0px`, a height that reads the model — so the layout cannot place row N without building rows 0..N, and Slint builds them all. The filtering moves to Rust, where the toggle was already reloading anyway. **The list must not be wrapped.** It carries its own stretch and preferred size, having no natural height to offer; a Rectangle in between hands the layout that Rectangle's constraints, which are taken from the list and are therefore nothing. **The panel must let it fill.** `Panel` lays its children out with `alignment: start`, which gives each its preferred height — right for a column of sliders, wrong for anything that scrolls. Hence `Panel.fill`. Get any of them wrong and the rail renders empty, with no error and a model full of people. All three were, in turn, before a headless render of the real screen showed a blank rail. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-30 18:30:16 +02:00
dtourolleandClaude Opus 5	f26f1ab694	Withhold the empty groups that fill the People rail ... `load_people` returned every live person, and on the reference library that was 14,268 rows of which 11,739 held no faces at all — 85 per cent of the rail naming nobody and able to do nothing. They are not a mystery. A regrouping pass creates a person per cluster; the next pass moves those faces elsewhere and leaves the person it emptied behind. `faces::prune_empty_unnamed` exists for exactly this and runs only at the end of a pass, so nothing clears what accumulates between them, and the Identity screen never prunes at all. Each one cost a `for_person` query and a built row on every reload. This withholds precisely the set the prune already treats as disposable — empty, unnamed, not set aside — and no more. Filtered rather than deleted: a screen is being drawn, not a catalog repaired. Nothing is lost, a sync cannot resurrect what was never removed, and the prune stays the one place that decides these can go. An empty group with a *name* still shows. That one is not debris but the symptom of a real failure — a named person whose faces were regrouped out from under them — and hiding it would take away the only way to merge them back.

dtourolleandClaude Opus 5	e8b072c815	Say the app is starting before there is anything to say it with ... Nothing from our own code reached logcat on the tablet: 284 lines from the app's PID during a launch, every one of them from Hwaps, BlockMonitor, InputEventReceiver or nativeloader, and not even the version banner android_main emits three statements in. I could not find the fault in our wiring, and this commit does not claim to fix it. What it does is make the next launch say which side is at fault, and close a hole that is real whatever the answer turns out to be. What reading rules out, so nobody repeats it: install does call log::set_max_level. The Config carries an explicit tag and an explicit max level, and its env_filter is None, so android_logger's enabled() and filter_matches() both pass an Info record. Tee::enabled delegates to the console and gates nothing else. set_boxed_logger cannot have failed — its Err path drops the Tee, taking the LogFile with it, and the file on the device has content. And Tee::log calls console.log() unconditionally *before* the file write, which is itself gated on console.enabled(), so every line that reached the file proves the AndroidLogger was handed the same record. Nothing else in the graph installs a logger; android-activity and Slint's backend do not. The diff that introduced this changed the level, the tag and the Config not at all — init_once and set_boxed_logger leave the same logger installed at the same level. That leaves below __android_log_write, which no amount of reading this file can reach. So: the console logger is now built first, and one line goes through it directly, before the state directory and before the log file. Two things follow. Everything between android_main's first statement and install returning — external_data_path, create_dir_all and an open on a FUSE volume the system may still be mounting — currently has no surface at all to fail on; that window is what logcat is for, and it now has a line in it. And when the log is silent, that line separates the two cases: present with the log::info! lines below it missing is the facade, absent along with them is liblog not delivering this process's records. It goes through Log::log rather than log::info!, which is not a style choice: the facade's maximum level is Off until install sets it, so a log::info! there compiles and emits nothing.

dtourolleandClaude Opus 5	c62edd3317	Give the log a mode that the way off the device can open ... The log file has been on external storage since it existed, and the reason is stated at length in two places: /data/data/<pkg>/files needs run-as against a debuggable build, /sdcard/Android/data/<pkg>/files is a plain adb pull from any build, and a log nobody can retrieve is not a diagnostic. The file was then opened 0600, which cancels that decision out. On the tablet: adb pull -> remote open failed: Permission denied adb shell cat -> Permission denied run-as -> package not debuggable Every route off the device closed at once, on a file whose whole purpose is to leave the device. The mode is now per platform, because "who may read this" has two different answers and the directory above the file is what makes them differ. On the desktop, 0600 as before: $XDG_STATE_HOME/darkroom is in a home directory on a machine that may have other accounts, and nothing about that directory stops another local user reading a world-readable file. On Android, 0644: /sdcard/Android/data is drwxrws--x media_rw:ext_data_rw, so no other app can enter this app's subdirectory and anyone who can traverse it is holding the unlocked tablet, which already gets them the photographs the log merely names. What the read bits buy is adb pull, which runs as shell — able to traverse a --x directory, but then obliged to open the file as other. The mode is also applied twice, and the second one is the fix rather than belt and braces. OpenOptions::mode is a request: the kernel ANDs it with the process umask, and an Android application process inherits 0o077 from the zygote, so asking for 0644 there creates 0600 and reports nothing. It is ignored outright on a file that already exists, which every launch after the first has. fchmod is subject to neither, and is what the second call makes. The comment claiming the mode was "ignored by the FAT-derived filesystem Android presents as external storage" is gone with it. The device says otherwise: the file it produced was 0600 exactly. Two tests. One pins the literal mode per platform — only the desktop arm can run under cargo test, and the comment says so rather than implying the Android number is covered. The other reopens a log left behind with the wrong mode, which is the one assertion on the host that fails if the fchmod is deleted, since OpenOptions::mode cannot touch a file that is already there.

dtourolleandClaude Opus 5	23c3155128	Release 0.10.0 ... Three waves of work since 0.9.0. Culling gained the two instruments FR-CULL-3 asked for and never had: focus peaking, and a histogram that reads the sensor rather than the frame about to be displayed. Bursts group themselves. Masks can cover a whole category rather than one instance. The catalog now notices when it has been damaged and offers a way back -- restore a backup, or rebuild from the photographs, which were never at risk. A crash leaves a record. A log survives the process, on a path a tablet will hand back to adb, which is what makes the Android work debuggable at all. The APK compiles its own Java for the first time, so the app can receive a photograph from another application and hand one back. Memory pressure is answered in a stated order. A lost library root is reported rather than reported as an empty library. There is a benchmark suite now, so §8's promise that a regression fails the build is a mechanism rather than a sentence. Its first run says the catalog opens in 70ms against a 2s budget, and that thumbnail throughput does not obviously reach its target. Coverage 59.8% -> 69.8%, and it means more than it did: five requirements that were tagged on code that did not implement them are no longer, and the tool no longer counts its own test fixtures.

dtourolleandClaude Opus 5	94b1b9e0cc	Reconcile what four branches each built separately ... Three seams, found by the first compile after the merge. Two branches implemented 'can this scope be reordered' independently: one from the collections model, one from the catalog through orders_manually, on every re-read and excluding the trash. The second is the better answer and is what survives; it only needed to set the property app.slint declares. Two lints from scene-mask-ui, which was merged mid-flight and had never been through -D warnings: an is_none check spelled out where clippy wants ?, and a return in a cfg block's tail.

dtourolleandClaude Opus 5	df06240b2d	Test that the category geometry means what it says ... The scene tests so far checked the descriptor and the arithmetic. Neither would have noticed if `rasterise` put the sky along the bottom of the frame, because both build their own weights and never ask where those weights land. Three that do: - **Weight stays on the side it came from.** Fill the top half of the grid, read the top and bottom quarters of the image. A flipped y axis is the mistake this code is actually prone to — it is a letterbox inverse, and the numbers stay perfectly plausible when it is wrong. - **No transpose.** The vertical check alone passes under a transpose, which maps a top band onto a left band. A horizontal split is what distinguishes them, and neither test is worth much without the other. - **Coverage is a fraction.** A quarter of the cells must read 0.25. The scene tab hides a category below half a percent, so an error of a factor of the grid size would hide everything or nothing — and both look like the model failing rather than the arithmetic. `Scene::from_weights` is test-only and exists because the property under test needs weights whose correct destination is known in advance, which no real inference can provide. It uses a square window so the letterbox is the identity: any offset these find is the mapping's own rather than the padding's.

dtourolleandClaude Opus 5	86260b5028	Bind a category layer to its own distance field ... A category mask showed nothing and its adjustment covered the whole photograph. Both from one line: the loop in `MaskPass::rasterise` picks a distance field by matching `layer.source`, that match named only `Subject`, and a `Category` layer fell through to `_ => (&self.empty_subject, 0)` — a 1x1 placeholder. No field, so nothing to draw and nothing to confine the adjustment. The comment three lines above the arm I missed describes the failure I then shipped: an absent mask that defaults to "everything" would apply the adjustment to the whole photograph There are *two* matches on `layer.source` in that loop — one choosing the field, one building the params. Adding the category to the second and not the first compiles, runs, and is wrong in exactly the way the first one warns about. ## Also: a missing mask must still be the right size Both model-backed arms of `ensure_subject_fields` used `unwrap_or_default`, which yields an empty `Vec` when the coverage is gone. `SubjectMasks::upload` rejects a wrong-sized field and fails the whole batch, so `self.subjects` becomes `None` and *every* layer in the stack loses its mask — one stale reference silently unmasking the others. Pre-existing, and it mattered less when the only model-backed source was a subject: an instance index goes missing rarely. A category name goes missing whenever the descriptor is edited, which is a thing the descriptor exists to allow. A full-size empty field costs one layer instead of all of them. Neither of these is reachable from a test on this machine — both live past a GPU adapter and a real segmentation — so they surfaced the only way they could, by someone opening the app and looking.

dtourolleandClaude Opus 5	677146883f	Decide what the header gives up when it cannot hold everything ... Three faults, all invisible in the source and all found by looking at the window. `alignment: start` on the selection bar. Slint only hands space to `horizontal-stretch` children under the default `stretch` alignment; under `start` every child takes its preferred width and the stretch is ignored without complaint. That was harmless while the bar held four controls. Now that it holds every selection verb it is the difference between a count that gives way and a row that can only scroll, so the alignment goes and the stretch does its job. The title collapsed to "…". An eliding Text has a minimum of nothing, so once the buttons had taken their own minimums the title was the cheapest thing in the row to give away — the window stopped saying which library was open while the byte counts beside it stayed. It gets a 90px floor. And the status line does not get one. After the sidebar takes its 232, a 1100pt window leaves this header about 868, and the buttons want most of that before a character is drawn — so something must degrade, and the order is the whole question. A floor here bought a readable status by pushing Settings off the right edge, reachable only by knowing to flick-scroll, which is precisely the fault the row's own Flickable comment warns about. A control you cannot see is worse than a sentence you cannot finish. The status line is also the most redundant thing in the header — the sidebar states the library's count and the filter chips state it again — so it is what gives, and it grows back the moment there is room.

dtourolleandClaude Opus 5	7f350e8c4c	Offer the categories in the masks panel ... Everything before this was reachable only from an example that writes PPMs. This is the part a photographer can touch: a list under the subjects, click one, get a mask layer for every pixel of that category. ## Under the subjects, and the order is the argument Clicking the photograph is how a local adjustment usually starts, so the things the model *found* come first. A category is the move you reach for deliberately — grade the sky, not this one bird — and putting it second says so without a word of explanation. Coverage is shown for the same reason a subject's score is: it tells the photographer whether a category is worth a click before they spend one finding out. ## Not a new tab, which is what was asked for A develop tab is derived from `Attribute`, not declared — the tabs exist because operations claim an attribute, and no amount of Slint adds one. A seventh attribute would have meant duplicating every adjustment once per category, and the combinatorics get silly by the third. Reached through masks instead, a category composes with every adjustment that already exists, and inherits feather and falloff rather than needing its own. What was described as "per-category sliders with feather and decay" is exactly what this is; only the door is different. ## Verified as far as it can be here Compiles, populates, round-trips, 560 dr-ui tests green. **Not clicked** — synthetic input is blocked on this setup, so how it looks and feels is unverified and wants a human at the window.

dtourolleandClaude Opus 5	763dfd353a	Weigh the categories in the same precompute, and mask with them ... The scene model shipped with a decoder and no caller. This runs it. ## Beside the instance pass, not instead of it `compute` now does both on the same upright frame and lays both back down the same way, so instance masks and category masks index into one grid — the sensor's. A failure in the scene half is logged and dropped rather than propagated: no scene model is an ordinary state, and a photograph that can still be masked by subject should not become unopenable because the categories are missing. Categories under half a percent of the frame never reach the cache. A control that does nothing when moved is worse than an absent one, and each one it skips is a proxy-sized buffer not allocated. ## The shader needed nothing A category reaches `dr-gpu` as a soft coverage buffer at proxy resolution, turned into a distance field — which is exactly what a subject is. So they share `MODE_SUBJECT`. That is not a shortcut taken for speed: the shader has no way to tell them apart and no reason to want one. What differs is only which model produced the coverage, and that has already happened by then. Feather, falloff, dilation and erosion therefore work on a category on the day it arrives, because they were never subject-specific. ## Where the weights come from `scene-model` compiles the graph in and the desktop app takes it; Android leaves it off and reads the copy `install_bundled_models` unpacks, because 24 MB of constant is worth avoiding in a mobile install and not worth the plumbing to avoid on a desktop one. Embedded is tried first — a build that has the weights compiled in should not be silently overridden by a stale file in a data directory.

dtourolleandClaude Opus 5	485297f0c6	Let a mask cover a whole category, not just one instance ... `MaskSource` could say "instance 3 of that segmentation run" but had no way to say "the sky". Adding `Category { signature, name }` beside `Subject` is what lets a local adjustment attach to a semantic category at all. Stored as identity like a subject, and for the same reason: the coverage is megabytes and is reproducible by running the same model over the same image, so the sidecar carries what finds it again and the session carries pixels. ## A name rather than an index An index would be smaller and would match `Subject`. It would also be a bug. The grouping lives in `models/scene/categories.txt`, which is editable by design — adding one category to it renumbers every category after it, and every stored layer would silently start grading something else. A name that no longer exists is simply not found and the layer reads as stale, which is the failure that announces itself. Staleness is otherwise identical to a subject's: the coverage buffer is in the session, never the sidecar, so a signature from another run points at pixels that were never computed. ## Two tests, and the second one caught a real shape Round-tripping the name matters more than usual here, because the whole argument for storing a name instead of an index is worthless if the sidecar is what drops it. The multi-word case is the one worth having: `category = swimming pool` is written on one line, and a reader splitting on whitespace would have truncated it to a category no model has — a layer that silently masks nothing. `category` is also its own key rather than a reuse of `class`, because a file conflating them would round-trip a subject into a category.
