dtourolleandClaude Opus 5	0b20436445	Prove the plateau pass does nothing, and stop paying for it ... Picks up the lower-completion work a crashed session left mid-debug, with one failing test and no diagnosis. The diagnosis is that the pass is a no-op. Not "does not reduce basin count" — it changes *no pixel's basin at all*, zero of 9216, comparing one plateau iteration against sixty-four. That assertion is the substance of this commit: the original test asserted a consequence (fewer basins) which a working pass need not produce, so it could have been satisfied by weakening it. A no-op check cannot pass vacuously, and it is what turned an opinion into a fact. Three candidate causes were tried and none was it. Exact float equality is genuinely wrong and is fixed regardless — a gradient computed from 8-bit samples is never exactly equal across a region the eye calls flat, so `==` never fires and `<` fires everywhere; `LEVEL_EPS` now sits behind all three comparisons. The test image is not it either: a flat disc, a terraced disc and a constant-slope ramp all behave the same. The finding worth keeping is about the domain rather than the code. On a gradient-magnitude watershed every flat region of the picture is at gradient zero, the global minimum, and a plateau with no descending exit is a minimum — one basin already, nothing to resolve. The plateaux lower-completion is defined for are regions of constant non-zero gradient, which are rarer in a photograph than F1's phrasing implies. That may be the whole answer, or it may be hiding a fourth cause; I could not close it. So `plateau_iterations` defaults to 0. The implementation stays, correct as far as it goes and costing nothing until someone finishes it; the test stays, ignored with its reason; docs/segmentation.md §12 records what was ruled out so the next attempt starts further along than this one did.

dtourolleandClaude Opus 5	a8b28136a6	Merge the batch export, and settle the seven-branch merge ... Resolves the last of the parallel work. Two conflicts worth recording, because both were semantic rather than textual: `render_for_export` gained a colour space on master while the batch branch was rewriting the single-image export path around it. Kept both: the batch request supersedes the synchronous path, and the space still has to be chosen at render time because the conversion happens in the shader before the clip to 0..1. `render_open_frame` takes it as an argument rather than reaching for a controller it does not hold. The map-wait moved into `readback::await_mapping` on one branch while another was editing the constant it used, so `READBACK_POLL_LIMIT` survived the merge with no callers. Removed rather than left for clippy to find later. 1164 tests pass, clippy clean, fmt clean. Traceability 53.0% -> 54.3%.

dtourolleandClaude Opus 5	4b36ca66aa	Render an export into the colour space its file will claim ... The colour-managed export branch left one call site deliberately unfixed, and this is it. `render_for_export` composed with the default sRGB shader, so a Display P3 export failed with an accurate error rather than producing a mislabelled file — the right way to leave a half-finished path, and no way to leave it. The space is chosen at render time because that is the only time it can be: the conversion happens in the shader, before the clip to 0..1, so by the time pixels reach an encoder they are in exactly one space and the only honest thing left is to label them. `Frame::in_space` carries which, and a mismatch between what was rendered and what was asked for stays a typed error. Also regenerates the traceability matrix over the four merged branches. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-17 09:34:57 +02:00
dtourolleandClaude Opus 5	40d4e439a9	Drop the parameter the offline sidecar writer never used ... `write_one_sidecar` took an `Option<&NextcloudBackend>` it ignored. It was a leftover from the shape the write path had before online and offline separated into two functions: the offline one records to the cache and queues, and has no server to talk to by definition. A parameter that is always `None` and always unused says the opposite — that there is a case where it is `Some` — and the next reader has to check. The closure it was threaded through is renamed to say what it does rather than how it is called. `run(None)` needed the reader to know what `None` meant; `queue_all()` is the sentence. Also regenerates the traceability matrix, which now records FR-CAT-9's queue. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-17 07:17:31 +02:00
dtourolleandClaude Opus 5	cb1d2be240	Choose the export folder by walking the server, not by typing it ... The destination for a Nextcloud export was a text field. Nobody recalls the exact spelling of a path three levels down, and getting it wrong does not fail — `create_dir` makes whatever was typed, so a misremembered folder becomes a new one at the root and the exports are somewhere nobody looks. So it is picked the way the library root is picked, using the same `FolderBrowser` model the launch screen drives: up, into, and "use this folder", confirming the folder currently *shown* rather than one selected in the list. Same rule in both places, so the phrase means one thing. The model is shared; the worker is not. `settings_ui::spawn_folder_list` is a near-twin of the launch screen's, because that one reaches into the `LaunchController` for its session and reports onto the launch screen's error line, while this one is handed credentials and writes to the settings page. Factoring them together needs a function taking both controllers or a trait implemented twice to abstract two call sites — more machinery than the twenty lines it saves. What matters is shared already: navigation behaves identically because both drive the same model. The callbacks are wired in `lib.rs` rather than in `settings_ui::wire`, because listing a remote folder needs credentials and the settings page holds no session on purpose — it is reachable before a library is opened and must not depend on one existing. With no account the picker says to sign in first, rather than showing an empty list that reads as a server with no folders. Details that are decisions rather than accidents: the picker opens at the library root rather than at whatever half-typed path is in the field, which would list nothing and look broken. The listing area is a fixed 180px, since a folder with sixty children would otherwise push the rest of the settings page off the bottom. "Up" is disabled at the root rather than hidden, so the row does not jump as the user navigates. A failed listing leaves the picker open on the folder it was showing — where the user had got to is not something to discard over a dropped request. And the chosen folder saves immediately like every other setting on a page that has no Save button. The poll timer lives on the controller for the reason `LaunchController` keeps its own there: a `slint::Timer` stops when dropped, so one local to the function that starts it would be collected before the listing arrived. Carries in-flight work from a parallel session — a segmentation pass in dr-gpu, a sidecar cache, and the develop panel's continuing changes. 1020 tests pass, fmt clean. One clippy warning remains and is not mine: `sidecar_cache::dir` is unused while that work is in progress. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-17 07:12:01 +02:00
dtourolleandClaude Opus 5	e00c99b864	Let a photograph leave: an export button, and a cache to leave from ... dr-export could turn a frame into bytes and nothing could ask it to. This is the button, and the place the bytes go. **Everything is staged first.** An export bound for the server is written to a local outbox and uploaded afterwards; offline is not a special case, it is the same path with a drain that finds the server absent. Doing it the other way — upload directly, stage only on failure — makes the failure path the one that is rarely exercised and always broken, and a network drop mid-batch leaves some exports existing and some not with nothing recording which. Staged first, an export is finished the moment it is written and the upload is a promise kept later. The outbox sits beside the catalog rather than under the cache. dr_catalog's cache already draws that line: passive entries are a convenience and go under LRU, pinned ones are a promise and never do. An export awaiting upload is a promise — the user was told it succeeded — and sweeping it for disk would destroy the only copy. Bytes are written before the destination record, so a kill between the two leaves an orphan the drain ignores rather than a record pointing at nothing. The status line says "Queued for Exports/2026", never "Exported to Nextcloud", until it has actually landed. There is a test asserting that wording, because the tempting shorter sentence is a claim the app cannot keep. The drain runs on the sync pass, before the shards: a thumbnail shard can be rebuilt from the originals and the catalog is an index, but a queued export exists nowhere else. `DevelopSession::render_for_export` renders the framed size rather than reusing the frame on screen, which is deliberately viewport-sized (FR-DSP-1) — encoding that would hand the user a soft, screen-sized file with nothing to say anything had been lost (FR-EXP-9). One compromise, recorded rather than hidden: the export runs synchronously on the UI thread, so the window is unresponsive for the few hundred milliseconds a full-resolution render and encode takes. Moving a DevelopSession and its GPU pass to a worker is a larger change than one button earns, and it is batch export that makes the wait intolerable rather than merely noticeable. Still missing: the Nextcloud folder *picker*. The destination is typed into Settings for now. `FolderBrowser` in launch.rs is already the reusable model for it — it browses a remote tree and nothing about it is specific to choosing a library root — but wiring it into the settings page needs a listing worker and browser UI there, which is its own piece of work. Carries in-flight work from a parallel session — presets, the develop copy and paste, and the node schema's `presentation` and `enum` support. One misplaced callback in settings_ui.rs is moved from `render` to `wire`: registered in `render` it borrowed a `&SettingsController` into a 'static closure and would not compile, and that file's own docs say render pushes properties while wire connects callbacks. 992 tests pass, clippy and fmt clean. Traceability 48.3% -> 51.0%. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-16 23:58:17 +02:00
dtourolleandClaude Opus 5	151dcc3c02	Make a file out of a photograph ... Export existed as a settings page and nothing else: format, quality, colour space, five sizing modes, a filename template and a metadata switch, all configurable in detail, and no way to produce a single file. dr-export is the other half. **It returns bytes and a name, and writes nothing.** An export has three destinations with nothing in common — a path on Linux, a SAF document on Android where there is no path at all (ARCH §6.9), and a PUT to a Nextcloud folder — so a crate that opened the file itself would serve one of them and be rewritten for the other two. The caller places the bytes. Resize, then sharpen, then encode, in that order and for a reason: output sharpening compensates for the softening the resample introduced, so its strength scales with how much scaling actually happened, and sharpening before shrinking would throw the result away. Lanczos-3, separable, with weights computed once per output row — FR-EXP-4 asks for Lanczos or better because a box filter turns a distant fence into moiré. Collision handling takes the "is this name taken" test as a closure rather than looking at a directory, because there is no directory it could look at that works everywhere. That shape is not politeness toward Linux: Android's createDocument renames on collision by itself and cannot overwrite at all, so all three CollisionPolicy settings need the answer *before* anything is created. Overwrite, Skip and Increment are each tested, and Increment gives up after ten thousand rather than spinning against a destination that reports everything as taken. Three things are honest rather than done: - **Colour space.** sRGB only. The shader encodes and clips to sRGB before this crate sees a pixel, so tagging a file Display P3 would claim a gamut it does not contain. Refused with a typed error instead of mislabelled; honouring it is a pipeline change (FR-EXP-2). - **AVIF and JPEG XL.** No encoder. libaom and libjxl are C, ravif is slow enough to change what a batch feels like, and the settings page offers both because FR-EXP-1 lists them — so asking for one says so rather than writing a JPEG under a .avif name. - **16-bit TIFF** is a real 16-bit file carrying eight bits of information, because AdjustPass renders to Rgba8Unorm. Widened by *257, not <<8, so white lands on 65535 rather than a quarter-percent grey. Making it mean what it says needs the composer told what format to write. Metadata is not written at all, which satisfies the half of FR-EXP-8 that matters most: strip_location defaults to on, and a file with no EXIF block has no GPS tag. Retaining camera and copyright when asked is not implemented and cannot be faked by omission. Also here: - `AdjustPass::export_pixels`, ungated where `read_output` is behind a feature. The two are the same transfer and opposites in intent: reading pixels back to *display* them is what ARCH §6.1 forbids and AC-8 asserts against, while reading them back to encode a JPEG is the only way a file has ever been made. Separate methods so the instrumentation can count one without counting the other. - `ExportTarget`, so a destination can be a folder on the server. On Android that is the only destination needing no platform work whatsoever — a PUT against create_dir, already on the RemoteBackend trait, behaving identically on both platforms. Switching target clears the destination, since a path is not a remote folder and carrying one across would offer to create a folder called `home` at the library root. Verified end to end rather than by unit test alone: `cargo run -p dr-export --example export` decodes a frame, runs the develop chain on the GPU at full resolution, reads it back, and writes all five formats — 27 ms for a full-size JPEG, 165 ms with a Lanczos reduction to 1200px. ImageMagick agrees the 16-bit TIFF is 16-bit. dr-export cross-compiles clean for aarch64-linux-android; all three encoders are pure Rust, which is why they were chosen. 944 tests pass, clippy and fmt clean. Not yet wired to a button. The develop view has no export action, so nothing in the running app can reach any of this yet.

dtourolleandClaude Opus 5	d7aeafaf84	Move to wgpu 29, the version Slint can share a device with ... Groundwork for spike S1. Importing a texture into a Slint scene requires it to come from the *same* `wgpu::Device` Slint renders with, and Slint hands out a device of the version it was compiled against. Slint 1.17 offers `unstable-wgpu-28` and `unstable-wgpu-29` and nothing older, so wgpu 23 could never have met it: two semver-incompatible wgpu crates in one tree are two distinct types, and the device would not typecheck across the gap. The version is therefore not a free choice, and the manifest now says so — Slint and wgpu move together or not at all. The Slint requirement is also corrected from "1.9" to the 1.17 it has actually been resolving to. Nothing about the render path changes here. The readback bridge is still in place and still the display path, so this is verified by the tests that already existed rather than by anything new: 39 dr-gpu tests, which compare real pixels off a real device, and 888 across the workspace, all passing. Zero-copy lands separately and small. What the six releases cost, in full: - `ImageCopyTexture`/`ImageCopyBuffer`/`ImageDataLayout` became the `TexelCopy*` names (24). - `Instance::new` takes the descriptor by value, and `InstanceDescriptor` lost its `Default` — it carries a boxed display handle now, so a headless context says `new_without_display_handle` and means it. - `request_adapter` returns `Result` rather than `Option` (24). - `DeviceDescriptor` absorbed the API trace from `request_device`'s second argument and gained `experimental_features` (25). - `PipelineLayoutDescriptor` takes `Option<&BindGroupLayout>` per slot, and `push_constant_ranges` became `immediate_size`. - `Maintain` became `PollType`, and `poll` is fallible. Two of those are improvements worth having rather than churn. The error scope is a guard whose `pop` runs on drop, so an early return from the pipeline compiler no longer leaves a scope open on the device for whatever ran next to fall into. And a fallible `poll` reports a lost device (NFR-R7) at the point it happens, where before the map callback simply never arrived and the failure surfaced later as a readback that spun out its poll limit. Still to do for S1: dr-ui renders through `renderer-femtovg`, which is OpenGL. Texture import needs Slint itself rendering on wgpu.

dtourolleandClaude Opus 5	3b0950c39b	Regenerate the matrix that dr-thumbs moved out from under ... Commit 9a51cc8 edited core/dr-thumbs/src/lib.rs and pushed its TRACES tag from line 341 to 376 without rerunning the extractor, so the two rows that cite it — FR-CAT-15 and NFR-RES-4 — kept pointing at a line that is now something else. Nothing else in the report changed. The matrix records line numbers, so any edit above a tag dates it; the CI step exists precisely because that staleness is invisible in review.

dtourolleandClaude Opus 5	9a51cc88d6	Give a shard's remote name the client that wrote it ... Shard ids are per store: every client fills its own numbering from 0, so "shard 3" names different thumbnails on every device. The derived sync published them into a flat shard-NNNN.sqlite namespace anyway, which left two clients writing one name. Both failures that follow were live. On upload, a client's open shard overwrote a peer's file of the same id — content the peer still believed was published and would never restore, because its own copy was sealed and the name existed. On download, the loop skipped any remote id it already held locally, which is the only safe reading of a name that says nothing about who wrote it, so a client holding shards 0..5 never fetched the peer's 0..5 at all. Between them, two populated clients exchanged almost nothing: only shards numbered above the other's highest. A fresh device worked, having no local shards to collide with, which is why this went unnoticed — it is exactly the case the feature was written for. The name is now shard-<client>-NNNN.sqlite. The client id is minted per store in index.sqlite, beside the numbering it qualifies rather than in settings: a store deleted and rebuilt restarts at shard 0 and must not claim the remote names its predecessor wrote. Since our own ids now say nothing about what we have taken from others, index.sqlite also keeps a ledger of adopted remote names and the size each had when merged. A size rather than a flag, because a peer's sealed shard never returns but its open one grows, and re-merging the grown copy is how the thumbnails it gained since arrive. Flat names already on servers still parse, reporting no owner, so each client adopts them once, and nothing is written under that form again. One whose id and byte size match a local shard is that client's own earlier upload by the same identity argument the upload path already makes for sealed shards, so the rename does not cost every client a re-download of its whole store. Older builds ignore the new names and stop receiving shards until updated; their own uploads are still adopted, so nothing is lost.

dtourolleandClaude Opus 5	7c57f490fe	Declare a develop operation in YAML, and generate the rest ... An operation was, in the overwhelming majority of cases, four facts: what its parameters are, what uniforms they compute, what WGSL those uniforms drive, and where it sits in the chain. Written in Rust those four facts arrived wrapped in ninety lines of trait implementation — a match on parameter id to a struct field, another match back, an is_active comparing each field to its default, a Vec<Uniform> built by hand. All mechanical, and each one a place to make a silent mistake: a param() arm returning the wrong field reads perfectly and breaks the sidecar round-trip. So the four facts are the file now. core/dr-pipeline/ops/<id>.yaml is a node, build.rs compiles it into the same Operation impl as before, and the result lands in OUT_DIR — the same reasoning as style.yaml -> theme.slint, including why it does not land beside the sources it would look exactly like. Nothing downstream can tell a declared node from a hand-written one: same &'static OpDescriptor, same fused-shader composition, same sidecar. Nine nodes moved: exposure, white_balance, contrast, highlights_shadows, blacks_whites, brilliance, vibrance, saturation, and the shared WGSL helper registry. Their prose came with them, and so did their tests — set/expect/expect_active/expect_wgsl in the declaration compile to real #[test]s, so a node file carries its own proof rather than leaving it behind in a file that no longer exists. Two stayed in Rust and say so with `rust:`. The tone curve's neutral is a relationship between five interpolated points rather than a set of values; the colour mixer generates thirty-six faceted parameters from twelve computed hue bands. A schema stretched to cover either would be a worse language than Rust aimed at one caller. They still declare their position here, because the chain's *order* is the one thing a reader comes to this directory to learn, and an order written half in YAML and half in Rust would be worse than either alone. default_chain() is generated from it. Uniforms are derived by a small expression language — exp2(exposure), blacks / 100 * 0.02 — compiled to Rust rather than interpreted, so an unknown name or a wrong arity is a build error naming the file and the key and the arithmetic costs nothing at runtime. The build script refuses a duplicate order, a filename disagreeing with its id, a default outside its own range, a test value the graph would clamp before the node saw it, a helper that does not define the function it names, and a declared node colliding with a file in src/ops. Verified by adding a scratch node and removing it again: one file, no other edit, and it joined the chain at its declared order with its test running. 237 tests pass in dr-pipeline, clippy and fmt clean. .yaml joins the traceability tool's scanned suffixes, because a node's Rust now lives in OUT_DIR where a tag could never be linked from the report. Coverage 47.7% -> 48.3%. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-16 21:08:16 +02:00
dtourolleandClaude Opus 5	65e6a96a65	Say what the application is doing, in one bar and one list ... Every background job reported into a window property of its own — library-thumbs-done, library-pin-total, library-syncing — which only the grid ever read. A pin download that outlived the view it was started from drew nothing at all once the user opened an image, and there was no answer anywhere to "what is this busy with", because the answer was spread across eight properties nothing collected. They report to one register now (ui/dr-ui/src/activity.rs). It publishes an aggregate, which draws a three-pixel bar across the top of the shell in every view, and a row per job, which the settings page lists: scans, thumbnail batches, pin and open downloads, sidecar uploads, the sync and the trash. Failures stay on the list until they are cleared; routine successes do not, or a scroll would bury them. The handle removes a still-running job when it drops, so a worker that dies mid-transfer takes its row with it rather than leaving the bar sweeping for the rest of the session. Also carries in-flight work from a parallel session — the drawn icon set and the dr-pipeline ops split. dr-pipeline's build script does not compile at this commit; ui/dr-ui does, with clippy clean and its tests passing.

dtourolleandClaude Opus 5	70435b712e	Walk the grid with the arrow keys, and open with Return ... A cull is thousands of decisions. The grid already bound 0-5, P, X and U so the judgement itself needs no mouse, and then made the photographer reach for one to move to the next frame — which is most of the gesture, most of the time. Arrows now move a cursor, shift+arrow extends the selection, Home/End and PageUp/PageDown cover ground, and Return opens what the cursor is on. The cursor is a library ordinal, not a row of the loaded window. The window is a few screenfuls around wherever the user is looking, so a cursor held as a row would stop at its edge or keep counting into cells belonging to other photographs; walking out of the window reloads it around the new position, exactly as scrolling does. This is the argument the selection already made by keying on ids rather than rows. The anchor had that fault for real: it was a window row, so a shift-click after a scroll extended from whatever image had since drifted into it. It is an ordinal now, and apply_press takes the window's offset to map between the two. A range longer than the loaded window truncates to what is loaded, since selection is by id and an image the catalog has not been asked for has none. The pointer and the keyboard share select_row so the two cannot drift apart. The one deliberate difference: a plain arrow collapses the selection onto the cursor, where a plain click on an already-selected cell leaves it alone — that exception exists so a multi-image drag can start from one of its members, and there is no drag behind a keystroke. The grid scrolls to the cursor only when the cursor leaves the viewport, and then by as little as will do it. Reusing the scrub's seek() would put the cursor's row at the top on every press, which makes a row unreadable as you walk along it.

dtourolleandClaude Opus 5	9b2ee0d0eb	Show the colour mixer as three runs of twelve, each row a colour ... The mixer was thirty-six sliders reading "Hue / Sat / Lum" twelve times over with nothing saying which band any row belonged to. The identity was there all along — the descriptor declares param.mixer.orange.sat and BANDS carries orange at 30° — and was discarded on the way out: labels.rs had no mixer entries, so every key fell through to a derived label that yields the bare channel name. A parameter can now say which aspect it adjusts and which subject it adjusts it on, with the subject's hue where the subject is a colour (descriptor::Facet). That is data about what the operation does, not a layout: the mixer genuinely weights pixels around 30°. What to draw from 30°, and in what order to stack the runs, stay in dr-ui (ARCH §4.3a) — develop.rs brings rows sharing an aspect together and marks the first of each, and adjust.slint names the run once and draws a swatch, a track and a readout on one line. Grouped by channel rather than by band because an edit is almost never "everything about orange"; it is the saturation of the greens, made by comparing one channel across neighbouring bands. Twelve band sections put those twelve rows in twelve different places. The swatch is the label, which is what makes twelve rows fit where four did. The band name is not lost: it is the row's accessible label, so the control is not colour-only, and labels.rs is where the mapping is written down — including chartreuse as "Yellow-Green" and spring as "Blue-Green", since nobody hunting foliage scans a list for "Spring".

dtourolleandClaude Opus 5	67c0237ddd	Make one slider, and take the lids off the develop column ... Two complaints from a tablet, with one cause between them. **Some sliders dragged and others only answered a tap.** They were not the same control. `ParamSlider` read its geometry from a `ParamRow` for the generated panel and `PlainSlider` took plain numbers for the straighten angle, each with its own track, handle, hit area and gesture rules written out separately — and a comment arguing the duplication was safe, because "a slider that dragged differently depending on which panel it sat in would be a worse inconsistency than the duplication". That is exactly what happened. The touch arbitration fixed in the previous commit went into `ParamSlider` and `CurveEditor`; `PlainSlider` kept the old code, so two sliders in the same sidebar behaved differently and which one you got depended on where you were dragging. The duplication failed to survive its first change. There is now one `SliderTrack`, owning the track, the hit area, the claim test, the hover arbitration, click-to-jump and double-click reset. The two wrappers differ only in where their numbers and labels come from. **Nothing in the develop column collapses any more.** Every group was a `Section` with a disclosure triangle, including five operations that carry a single parameter — so the lid was most of the row, wrapping one slider whose own label repeated the heading word for word. A control behind a lid is one the user does not know the pipeline has. `GroupHeading` keeps what the section was actually for: the name, the dot that says something inside differs from its default, and the reset. The reset is now permanently visible rather than appearing on hover, because a hover-only control is one no finger can reach. IMAGE goes back to flat as well. The column as a whole still closes, from the status strip — which is the control that was wanted, at the level it makes sense at. This costs no vertical space: `Section` defaulted to expanded and nothing ever set it otherwise, so the panel was already unfolded and the lids were overhead with no saving behind them. Verified with cargo test -p dr-ui (192), clippy at -D warnings, and an arm64-v8a release build installed on a tablet. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-16 15:38:23 +02:00
dtourolleandClaude Opus 5	489465faf0	Show the photograph the way it was taken ... Nothing read EXIF orientation, so every frame from a body held sideways lay on its side — in the grid, in develop, and in the read-only preview. The tag is honoured as part of *reading the file*, at the same standing as a RAW's masked-photosite crop, never as an edit. It lives as a baseline on Framing rather than as a starting value for quarter_turns, which is what keeps four things true: a sideways file opens unmodified, reset returns it to upright rather than to the sensor's scan order, its sidecar stays empty, and the rotate button still moves the image 90° whatever the file underneath it says. Framing::effective composes the baseline with the user's own turns through the group law rather than by adding turns and OR-ing flags. The naive version gets one case wrong — an odd baseline turn plus a user mirror — and gets it wrong quietly, because the result is still a plausible orientation. The composition collapses to a single permutation, so obeying the tag costs nothing per pixel. dr_decode::orientation is a header-only IFD walk, separate from metadata() for the reason the entry points are separate at all: the grid asks once per cell and must not build a rawler decoder to get one tag. CR3 and RAF fall back to the full read, being neither TIFF nor JPEG. Written down as FR-DEV-3h. Known gap: thumbnails cached before this stay sideways. The store is keyed by file and size, and its shards sync — invalidating them would have every client re-download 25 MB a shard, which is not this commit's call to make.

dtourolleandClaude Opus 5	fe66eba87f	Write down the trash requirement the code already implements ... The traceability gate failed on an orphan tag: seventeen sites across dr-catalog, dr-sync, dr-thumbs and the UI claim FR-CAT-15, and requirements.md defines FR-CAT-1 through FR-CAT-14. Not a typo and not a renumbering — the trash was built, designed and documented in the modules that implement it, and the requirement itself was never written. An orphan is the gate working: a tag naming an undefined ID would otherwise count as covered, which is how a matrix comes to report coverage of things nobody specified. FR-CAT-15 now says what trash.rs does, in the terms the module already argues: a soft delete moves the file into `.darkroom-trash/` and the catalog records that it happened, because a flag alone would not survive invariant 5.2.4 — the catalog is rebuildable from sources, so a rescan would find every deleted file still in the library and re-index it. That is also why the scanner exclusion is part of the requirement rather than an implementation detail; the folder and the exclusion are one mechanism and neither works alone. Permanent delete removes the file before the row, a delete of something already gone counts as success, and the count and bytes are shown before emptying. docs/traceability.md is regenerated: 150 requirements, 71 covered, no orphans.

dtourolleandClaude Opus 5	94a2686dcb	Fit the interface to the system bars, the finger and the back key ... Four faults that only show on a device, and one that was hiding on the desktop too. The system bars. Target SDK 36 forces edge-to-edge, so the window spans the display and the develop status strip was drawn underneath the clock and the wifi icons. Slint already computes the inset from Android's OnApplyWindowInsetsListener and exposes it as Window.safe-area-insets; nothing read it. The four views now sit inside a shell placed within the safe area. Every inset is zero on the desktop, so that layout does not move. Sliders under a finger. A Flickable steals any gesture that drifts more than 8 logical pixels along its scrolling axis within half a second of the press, and it steals it by cancelling the child. ParamSlider's axis test correctly declined to claim vertical drags, but nothing told the Flickable to stand down once a drag was claimed — so an adjustment would start moving and then be taken away mid-motion. A mouse holds a horizontal line closely enough to stay under 8px; a finger does not, which is why these worked on the desktop and not on the tablet. The claim now sets `interactive: false` for the rest of the gesture. The tone curve had the same fault and worse: its points are dragged vertically, which is the Flickable's own axis, so every drag was stolen — on the desktop as well. The back gesture. Nothing handled it, so back closed the application from anywhere in it. Android delivers it as Key.Back to the focused item and bubbles it up the ancestors, which is the second reason the shell wraps the views rather than sitting beside them. The order is innermost first: settings, then crop, then zoom, then develop to the grid, then a collection scope. Answering false at the top of the stack leaves Android to close the activity, as it does for every other application there. Escape does the same on a keyboard. back_step is a pure function over a flat NavState so the ordering can be tested without a backend: which of two states is left first is the whole of the feature, and it is the part that is easy to get subtly wrong when spelled out in nested ifs over live properties. Develop's canvas now takes focus on show. Without it the arrow keys did nothing until the canvas was clicked, and Key.Back had no focus item to bubble from. Panels that close. The collections sidebar and the develop column are collapsible from the grid header and the status strip. The layout class now supplies only the default: a panel closed to see more of a photograph stays closed while the window keeps its shape, and the choice is dropped when the class changes, because rotating a tablet asks a different question from the one answered in landscape. IMAGE became a Section, being the only group in the column that could not be put away and the one whose content is read first and needed least. Pinch to zoom on the develop canvas, anchored on the midpoint between the fingers (FR-UI-4). The wheel is the desktop's answer and there is no wheel on a tablet. The develop status strip was 28px against the 44px headers on the library and settings pages either side of it — the one screen where a way out has to be found was the one drawn smallest. All three now agree. Verified with cargo test -p dr-ui (192 passing, 6 new), clippy at -D warnings, and an arm64-v8a release build packaged to an APK.

dtourolleandClaude Opus 5	fa12afed18	Keep originals on this device, by pin and by use ... Fills in `image_cache`, which the previous commit's "On this device" filter read but nothing wrote. Also carries in-flight work that shared these files: the Android TLS root store, the settings page, and a regenerated traceability report. # Two populations, deliberately separate An original is kept here for one of two reasons, and conflating them produces the exact failure the feature exists to prevent. **Pinned** originals were asked for. Pinning a collection before a trip is a promise, so pinned rows are never evicted and never counted against the budget — a cap that could silently delete a pinned trip would make pinning worthless, because it could not be relied on without checking. **Passively cached** originals are a side effect of working: develop already downloads the whole file, so keeping it costs no bandwidth and saves the entire transfer next time. This population is what the budget bounds, evicted least-recently-used, because it otherwise grows until a day of culling fills a disk. Sharing one budget would let a large pin starve the passive cache, or let browsing evict a pin. They are separate. # What was built `dr_catalog::cache` owns the bookkeeping — held tier, size, last use, pinned — and writes the bytes; deciding to download stays with the caller, which is what keeps a crate with no network out of the network's business. Files are written to a temporary and renamed, so a dropped connection cannot leave a truncated file recorded as a complete original. They are named by image id, not filename: `Photos/IMG_0001.CR2` and `Trips/IMG_0001.CR2` are different photographs, and a flat cache keyed on the name would serve one for the other. `spawn_full_fetch` became read-through. A hit is a disk read; a miss stores what it downloads and enforces the budget. A cache that cannot be opened is a miss, not a failure to open the photograph. Pinning writes intent — `tier_desired` — without downloading, so the button responds immediately, and `spawn_pin_fetch` fills it in sequentially afterwards. Sequential because these are tens of megabytes each: the lanes that make the thumbnail sweep fast buy little against one connection's bandwidth and cost a great deal of memory. A pin interrupted by a lost connection resumes from where it stopped. Schema v5 adds `pinned` and `path`. `pinned` is a column rather than something inferred from `pinned_by_rule`, which is ON DELETE SET NULL and so cannot answer for an image whose rule was deleted. A v4 catalog migrates in place; existing rows default to unpinned, the safe direction. The budget and "keep opened originals" come from the settings page rather than a constant, and are applied at startup rather than only on change — a cache capped at 2 GB last session would otherwise spend this one filling to the default. Turning off keeping leaves what is already cached readable: those bytes are paid for, and refusing them would re-download images sitting right there, including pinned ones. Also removes a doubled `#[test]` introduced in the previous commit. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-11 21:12:01 +02:00
dtourolleandClaude Opus 5	d49b4b41de	Add thumbnail size classes and grid zoom; fix the scrub ordinal ... The grid now zooms, which needs thumbnails at two resolutions rather than one, and exposed a scrub that landed in the wrong place. **Two thumbnail size classes.** `ThumbSize::Grid` (256px, ~10 KB) and `Large` (1024px, ~45 KB), with the class part of the store key so both coexist. Storing everything large would take the reference library from ~200 MB to ~860 MB, and shards sync, so that is transfer cost on every device rather than only disk. A store written before the class existed migrates in place: its entries are all grid-sized, which is what the column defaults to, so nothing already fetched is discarded. `forget` now drops every size for an image. Reading a single row left the other class's bytes on the shard's tally for good, sealing it early on space nothing occupied. **Grid zoom.** Ctrl+wheel and pinch resize cells between 90px and 420px in geometric steps, so the gesture feels the same at either end where a fixed pixel step would be imperceptible at 400px and violent at 90px. Crossing 256px switches to the large class, so a zoomed cell is sharp rather than upscaled. Columns and window capacity already derived from cell size, so the grid reflows for free. **The scrub landed about half a library too high.** It counted only dated images while the grid shows all of them — 10,733 dated against 19,841 rows — and ignored `shadowed_by`. Verified against the live catalog: the old formula gave 10,887, the new one 10,732, the true grid position 10,732. The scrub's count and the grid's window must use identical predicates and ordering; a test now fails if they diverge. **Timeline gestures are continuous.** Scrub and pan were quantised to whole buckets, so a slow drag did nothing until it crossed a boundary and then jumped a month. Both work in fractions of the visible span now, and pinch-to-zoom arrives for tablet, where there is no wheel to reach the axis with. The pinch accumulator was wrong on first writing: it took at most one step per update, so an 8x spread — three doublings — yielded one zoom level. `log2().trunc()` now extracts every whole doubling and carries the remainder. The original test asserted the wrong number and defended it in a comment, which is worth remembering: a test can entrench a bug as readily as catch one.

dtourolleandClaude Opus 5	02b66ddfcf	Document trash, collections, thumbnails, and the UI direction ... Specs for the work that follows: soft delete via a MOVE that preserves the remote id, the collection tree and smart collections, the thumbnail store, and the derived-state folder. Adds two design documents. ui-refinement.md names the structural gaps between the v0.1 UI and something that feels like a photo editor. view-composition.md proposes a view controller for the display layer, against the 500-line run() that has become one by accretion.

dtourolle	09e3043f4c	Add secure credential storage, sessions, and a launch screen ... Login now persists properly rather than through the JSON file the test harness was using. dr-plat SecretStore trait plus a Secret Service backend. Verified against the live GNOME Keyring: store, retrieve, delete, confirm-gone all round-trip. Session/SessionStore splits credentials from settings — the app password goes to the keyring (FR-NC-2), while server, login, chosen root and format selection are ordinary config. A test asserts the credential never appears in the config file. LaunchModel the launch-screen state machine, testable without a display server: sign in, approve in browser, choose folder, tick formats, sign out. launch.slint the screen itself, in its own file. Absence of a secrets daemon is an explicit degraded mode, not a silent fallback to plaintext — the screen says sign-in will not persist rather than letting the user find out next launch. Android's Keystore backend fails loudly for the same reason: a no-op store would look like it worked and then lose the credential. Two bugs caught by tests rather than by running it: - fail() after busy() signed the user out, because busy() had already discarded the session. A failed *scan* would have logged you out. Busy now carries the session. - normalise_server upgrades http:// to https:// rather than accepting it. NFR-SEC-3 requires TLS, and silently sending a credential in the clear is not a decision to make on the user's behalf. launch.slint is not yet wired into app.slint. Calling slint_build::compile twice replaces the generated module rather than adding to it, which broke the other in-flight work on dr-ui; I reverted that immediately. Wiring it needs an import inside app.slint, which is that work's file to change. 419 tests passing across ten crates.	2026-08-09 15:20:39 +02:00
dtourolle	c8bb08e661	Add folder scan with format selection; validate A3 on a real library ... Library setup as the user described it: pick a folder, choose which RAW types to look for, scan recursively. dr-types::FormatFilter the tick-box selection, seeing through VFS placeholder suffixes so a dehydrated CR2 still matches as a CR2 dr-sync::scan recursive walk, Depth:1 per directory, pruning unchanged subtrees where the backend propagates directory ETags Verified against nextcloud.tourolle.paris (34.0.2) on a real library: browse root 32 entries, 98ms scan PhotosRaw 17,185 RAW files in 334 directories, 34.1s (7,836 CR2 + 9,349 DNG) range read 262KB of a 21.5MB DNG in 119ms — 1.22% of the file, and enough to read "Canon EOS 6D | ISO 100" That last line is assumption A3 validated on real data. Cataloguing this library by whole-file fetch would move roughly 370GB; the range path moves a few MB. Pruning is capability-gated rather than assumed: with per-entry ETags a probe costs a request and proves nothing about children, so it is skipped entirely. A test asserts zero probes in that case. Still unresolved: /core/preview returns 400 for every parameter combination tried, including on a JPEG the server reports as having a preview. Not a request-shape bug — it fails identically bare. Recorded rather than worked around; ARCH §6.7 already treats server previews as opportunistic, so nothing depends on it.	2026-08-09 12:22:31 +02:00
dtourolleandClaude Opus 5	78e3e6b846	Add the develop pipeline: demosaic and seven raw adjustments ... Decode through display, on the GPU: black/white normalisation, Bayer demosaic, camera colour transform, and the first seven adjustment operations — white balance, exposure, highlights/shadows, blacks/whites, brilliance, vibrance, saturation. Composable shaders. Each operation contributes a WGSL fragment rather than owning a pass, and dr-pipeline fuses the *active* ones into a single compute shader. One texture read and one write per frame regardless of how many adjustments are in play, while the operations stay independent in Rust — adding one is a new file, with no central shader to edit. An operation at neutral settings contributes no code, no uniform and no branch. Uniforms are prefixed per operation so two may both declare `amount`; helpers dedupe by name from a single source of truth. Pipelines cache on a structure hash covering the op-set and its order but not the values, so dragging a slider uploads uniforms and reuses the compiled pipeline. Measured on a 24 MP CR2: 0.60 ms re-render, one pipeline compiled across ten slider positions. The UI is generated, not written. EditGraph::capabilities() reports parameters with their kinds, ranges, defaults and current values; the panel builds one control per entry chosen by ParamKind. No file in ui/ names an operation, and dr-pipeline has no wgpu dependency, so codegen is testable without a device (ARCH §6.5a). Three defects found against real files, each silent: - rawler 0.7.2's `xyz_to_cam` is all zeros — deprecated and no longer populated. The live matrices are in `color_matrix`, keyed by illuminant. Reading the old field yields no colour transform at all. - `cam_to_xyz_normalized()` returns all NaN on any Bayer sensor: it divides each of four rows by its own sum, and the unused fourth (emerald) row sums to zero. Inverting the 3x3 ourselves avoids it. `wb_coeffs[3]` is NaN for the same reason and is normalised at decode. - As-shot white balance reached the uniform block but no shader read it, so the first render of a real CR2 came out violently green. Green photosites collect roughly twice the signal of red and blue. Now applied unconditionally before any operation, with tests on ordering. Demosaic is Malvar-He-Cutler rather than bilinear: gradient-corrected interpolation at one 5x5 neighbourhood per pixel, where bilinear leaves visible zippering on any high-contrast edge at 1:1. Two of the four packed CFA constants were wrong on the first attempt, so all four layouts are asserted to reconstruct the same colour. Crop origins at odd coordinates re-phase the pattern; without that, red and blue swap. X-Trans reports GpuError::UnsupportedCfa rather than approximating with the Bayer path, which would look like a corrupt file. 206 tests, including GPU tests proving every operation and the full seven-operation chain generate compilable WGSL. Known gaps: the display path still reads back to the CPU each frame, which ARCH §6.1 forbids and AC-8 asserts against — it is gated behind the `readback` feature and waits on spike S1 wiring Slint's texture import. Curve shapes are a first draft and want tuning against real photographs. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-09 11:37:58 +02:00
dtourolle	cc1c5c892d	Support requesting VFS hydration; fix Android TLS cross-compilation ... Correcting the previous commit: I claimed VFS placeholders could not be downloaded. That was wrong. The desktop client exposes a socket at $XDG_RUNTIME_DIR/Nextcloud/socket speaking newline-delimited COMMAND:argument, and MAKE_AVAILABLE_LOCALLY:<path> does fetch the file. Verified against client 4.0.7: a 1-byte stub became a real 2.8MB file in 2.8 seconds. Implemented as dr-sync-nextcloud::desktop_client, deliberately optional. Android has no desktop client, no XDG_RUNTIME_DIR socket and no placeholders, so detect() returns None there and callers fall back to the connector. It earns its place only because it is ~30 lines with no dependencies: where a library already lives in a VFS folder, asking the client to fetch beats downloading a second copy over WebDAV and leaving the client's placeholder state inconsistent. What this does not change: hydration is whole-file, so it suits the original tier and never browsing. Filling a grid this way downloads the entire library. Range extraction remains the only mechanism satisfying FR-NC-3, and ARCH §9.0 now says so precisely. Also fixes two real Android build failures found by cross-compiling: - reqwest's `rustls` feature defaults to aws-lc-rs, whose aws-lc-sys crate is C and fails under the NDK — exactly the pain D1 chose Rust to avoid. Switched to rustls-no-provider + ring, installing the provider in the constructor so no caller can build a client that panics on first use. - ring itself needs CC/AR per target; cargo-ndk sets only the linker. Added them to the container. 87 tests passing. dr-sync-nextcloud cross-compiles for aarch64-linux-android.	2026-08-09 10:10:29 +02:00
dtourolle	f8a718f42e	Add Nextcloud connector; reject VFS as a transfer mechanism ... Investigated using the Nextcloud desktop client's Virtual Files as a cache instead of talking to the server directly. Measured on this machine (client 4.0.7): the configured folder holds 121,785 placeholders against 10,267 materialised files, including 7,037 CR2 and 9,411 DNG. Three findings, each independently disqualifying: - Linux VFS is *suffix* mode. A dehydrated IMG.CR2 exists only as IMG.CR2.nextcloud holding one byte; the real name is absent. - Reading a placeholder does not hydrate it. dd of the first 256KB returned 1 byte, the stub was unchanged, and the real name never appeared. There is no FUSE layer — the stub is an inert marker. - Even with hydration the granularity is wrong: VFS has two states, 1 byte or all bytes, and the preview tier needs a ~256KB prefix of a 27MB file. That is ~100x what FR-NC-3 requires. Recorded as ARCH §9.0. Coexistence is still supported: dr-types now recognises *.nextcloud stubs, and the viewer lists them as "not downloaded" rather than as corrupt files or not at all. So the connector talks to the server directly, as D7 specified. Implemented: Login Flow v2, PROPFIND with oc:fileid and nc:has-preview, ETag pruning via a Depth:0 probe, range GET with local slicing when the server ignores the header, conditional PUT, and /core/preview with forceIcon=false. delta() returns Unsupported and says why. Chunked upload v2 is not implemented yet — put() rejects bodies over 5MB explicitly rather than silently truncating. Two bugs found by testing: my hand-computed epoch in a date test was a day out (the parser was right), and quick-xml reaches EOF on truncated input without erroring, so unbalanced elements needed an explicit check — a half-parsed multistatus must not look like an empty directory. 83 tests passing.	2026-08-09 09:09:27 +02:00
dtourolle	9717e59909	Add RAW decode and a working image viewer ... dr-decode exposes four entry points rather than one decode, because callers differ sharply in what they need (ARCH §3.2): culling wants a preview, the grid wants metadata, only develop and export touch sensor data. Fusing them forces a full decode where a header read suffices, which is why Lightroom stalls ~2s per image while culling. Smoke-tested against 1,852 real Canon CR2 files (EOS 6D, ~27MB each): metadata 0.2ms from a 256KB header read, no full decode preview ~250ms 5472x3648, downscaled to 2048 for display jpeg 3.0ms Two findings worth recording: rawler 0.7.2's CR2 decoder implements only full_image; thumbnail_image and preview_image are unimplemented trait defaults returning None. So every rung of the preview ladder resolves to a full-resolution decode at ~250ms — 5x over NFR-P13's 50ms budget. CR2 does carry smaller IFDs, so the fix is our own IFD walk or an upstream contribution. The ladder is written now so that fixing it is a decoder change, not a change to every caller. Recorded in milestone-v0.1 risks. Preview.downscale_to bounds memory: a 5472x3648 RGBA preview is 79.8MB, which exhausts a phone's budget after a handful of images. Box-filtered so downscaled thumbnails do not alias. Also fixed a RefCell double-borrow that panicked on first navigation — `*x.borrow_mut() = *x.borrow() + 1` holds both borrows at once. Verified with 10,000 programmatic navigations. 58 tests passing. Traceability 20.3% (29/143).	2026-08-09 08:28:26 +02:00
dtourolle	0f202fd3f9	Add requirements traceability gate and Gitea pipelines ... Ports JellyTau's traceability tooling to Rust, carrying across the bug it was repaired for. That gate divided a traced count by frozen literal denominators; the requirements file outgrew them and it reported 158% coverage, so it could never fail its own threshold. Two rules, both enforced by the extractor's own tests: - denominators parsed from docs/requirements.md at run time - coverage is |traced ∩ defined| / |defined|, never a raw traced count The gate additionally fails hard on a misconfigured run — zero requirements parsed or zero files scanned — rather than reporting a plausible 0%, and on any orphan tag naming a requirement that does not exist. Adapted for DarkRoom: IDs are FR-CAT-1 / NFR-P13 / FR-DEV-3a shapes rather than JellyTau's fixed three digits, and decisions (D), spikes (S), milestone items (M) and test ids remain taggable while being excluded from the denominator — counting them inflated it by 25. Also adds dr-sync: the RemoteBackend trait and capability model, so the Nextcloud connector is one implementation rather than the only shape the engine understands. No mature Nextcloud crate exists (reqwest_dav is too thin), so the connector will be hand-rolled over reqwest per D7. Gitea workflows follow the same style: containerised, commented with the reasoning, desktop and Android on every push, plus a CI check that no core/ crate depends on the UI toolkit (ARCH §6.5a). Coverage today: 13.3% (19/143). 50 tests passing.	2026-08-09 08:01:32 +02:00
dtourolle	82a5e21ec6	Initial workspace: GPU context, compute pass, adaptive Slint shell ... Establishes the v0.1 foundations on both platforms: - dr-types: SourceRef (never a filesystem path — Android SAF has none), Format, Availability, Validator with ETag quote normalisation - dr-gpu: wgpu device, compute pass writing a storage texture, resize - dr-ui: Slint shell with FR-UI-1 adaptive layout, computed in Rust to avoid a binding loop - docker/android: pinned toolchain, verified producing API 28 ARM binaries Measured the cost of the temporary CPU readback path (dr-gpu bench): compute is 0.06-0.28ms across sizes while readback is 0.63-7.43ms, so readback is 90-96% of frame time and scales with area. Recorded in ARCH §6.1 — this is why spike S1 is the priority. Mitigations pending S1: reuse the staging buffer, apply at most one resize per frame, and cap render resolution at 2048 on the long edge. 10 tests passing; core crates cross-compile for aarch64-linux-android.	2026-08-09 07:42:05 +02:00
