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	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
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	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.

dtourolle	e8e96eed40	Measure the performance targets §8 has been promising, and fail on a regression ... docs/requirements.md §8 has said since it was written that performance is verified by "an automated benchmark suite against a synthetic 50k catalog, run per-commit … A regression beyond stated tolerance fails the build." There was none. No benches/, no [[bench]], no criterion, no synthetic catalog, and three CI workflows that between them measured nothing. Ten performance requirements could therefore be neither passed nor failed, and five of them carried a TRACES: tag regardless. tools/bench is the half of that promise that can be kept honestly on a runner with no GPU and no display. # The fixture Rows are cheap and pixels are not, so it builds fifty thousand catalog rows over a pool of a dozen real files, each referenced by several thousand of them. Everything the catalog half touches is rows and is exact at full scale; everything the pixel half touches is one file at a time and does not care how many rows point at it. Fourteen megabytes on disk instead of two terabytes, and neither half is flattered by the trade. It is reproducible from a seed, and a stamp beside it — seed, row count, source size, dr-catalog's schema version — rebuilds it rather than letting a run be compared against a baseline that describes a different library. # What it can now pass or fail NFR-P1, and R2's second sentence with it: Catalog::open plus the count, first window and timeline the grid cannot paint without. The interesting part turned out to be the open itself — schema::backfill runs three passes over the images table on every open, which is O(library) work on a path whose budget is stated in absolute seconds. Tagged TRACES: NFR-P1, on a gate that fails if it breaks. NFR-P3: thumbnail throughput on the embedded preview path, through the same per-image work spawn_thumbnail_sweep does and in the same shape — chunks of 96, lanes owning disjoint slices, the single thread that owns the store writing the finished chunk. Mirrored rather than called, because that function takes a RemoteBackend and would measure somebody's network. Tagged TRACES: NFR-P3. # What it deliberately does not claim NFR-P7 is the whole chain, and only the encode half of it runs without an adapter. So the export row is a one-sided gate — over two seconds in the encode alone violates the requirement; under it proves nothing — and there is no TRACES: NFR-P7 anywhere. NFR-P8 is about the application at idle, and the probe is a process holding the catalog and nothing else, so it records the catalog layer's share and carries no budget until somebody decides what that share should be. No tag there either. CONTRIBUTING.md asks that a requirement be closed by a test that would fail if the behaviour were removed, and two more plumbing tags is what this repository already has too many of. NFR-P8 also gets the answer §4.1 demands: RSS is exclusive of device-local GPU allocations and cannot be made otherwise, because such an allocation never enters the process's address space. The requirement should be restated as two figures, and docs/benchmarks.md says so. # Two gates, and why one of them steps aside off the reference desktop The budget is the requirement's own number and never moves. The baseline is what the reference desktop last measured, and drifting 15% past it fails the build even while still inside the budget — which is how performance rot actually arrives, never over the line, always a little worse. A budget written for twenty-four threads cannot be asserted on a two-core container. §8 names the reference desktop, not CI, so each metric declares whether its budget is machine-sensitive; those are asserted under --reference and reported everywhere else. Catalog open is not one of them: two seconds against an expected figure two orders of magnitude smaller is a threshold any machine can be held to. This is the trap core/dr-gpu/tests/frame_budget.rs already refuses — a red gate everybody learns to ignore. # The baseline ships with no numbers in it Every recorded field is null, because nobody has run it yet. Writing plausible-looking figures would make every later comparison a comparison against a guess, and the first real regression would be invisible. Run `dr-bench record --reference` on the reference desktop and commit the diff; until then the budget gate works and the report says the other one cannot. # CI .gitea/workflows/benchmark.yml, and its own workflow rather than a step in build-and-test.yml: a red "Build and test" says the code is wrong, a red "Benchmarks" says it got slower, and the second must not be reachable by retrying a flaky compile. The cpu job runs on every push and builds -p dr-bench alone — which is why that crate depends on no GPU and no UI crate. The gpu job is the frame budget that already exists and already skips without an adapter, on workflow_dispatch, because building wgpu on every commit to rediscover that the runner has no device is not a use of anybody's minutes.	2026-08-30 10:40:10 +02:00
dtourolleandClaude Opus 5	754ab91347	Bring a Lightroom library across, and start with something in the list ... Two halves of the same complaint: a preset sheet that opens on "No presets yet" is homework, and a photographer with ten years of presets in Lightroom has no way to bring them. `dr-preset-xmp` reads Camera Raw `.xmp`. The mapping turned out to be mostly a rename rather than a conversion, because Adobe and this pipeline already agree: exposure is in stops in both, and contrast, the four recovery controls, clarity, texture, vibrance and saturation are all ±100 in both. That is not imitation, it is the convention raw developers converged on — `highlights_shadows.yaml` cites it in as many words. Only sharpening needed arithmetic, Adobe's 0…150 against our 0…100. The white balance does not come across, and says so rather than guessing. Adobe writes absolute Kelvin for a raw file where ours is a relative nudge from what the camera recorded, so converting needs the *target image's* as-shot white balance — exactly what a preset cannot carry, since the same preset lands on a frame shot at 3200K and one shot at 7000K. A guess would be wrong on most images and invisibly so. A folder is read as readily as a file, nested, because that is the shape an exported preset folder is in and importing ninety files one at a time is asking someone not to bother. `dr_pipeline::starter` is six presets a first run begins with, written against this pipeline in its units and deliberately mild — a starting point, not a caricature. They are seeded when the library *file* does not exist rather than when the library is empty, so deleting all six does not hand them back on the next launch. Both of these name operations, and `ui_names_no_operation` was right to stop them living in `ui/`. That test exists because the failure is silent and cumulative, and it caught exactly what it was written for: a preset called "Punch" is a statement about contrast, clarity and vibrance, and a table mapping Adobe's vocabulary to ours is a statement about the pipeline. Neither is a fact about an interface. So the starter set went into `dr-pipeline`, and the importer into its own crate — between two walls, since `dr-pipeline` depends on nothing on purpose and XMP is real XML not worth hand-rolling.

dtourolleandClaude Opus 5	bbd26f05f9	Release 0.9.0 ... Thirty-five commits since 0.8.0, and two of them are the reason this is a minor rather than a patch. **Storage became pluggable.** A folder backend now sits beside the Nextcloud one behind the same seam, proved by a test rather than by a trait, and the launch screen offers three routes into a library instead of one. **Faces gained a confidence that means something.** A suggestion is scored against the people the user has actually named, the curve it came from is stated rather than implied, and a regroup runs roughly three times faster — the similarity scan and the merge engine both use the machine's own SIMD kernel now, measured on the tablet where the NEON path is the one that runs. Alongside those, the framing tools got the quality-of-life pass this release is named for: a crop can be held to a ratio, a straighten crops away the corners it exposed, an export can be pinned to an exact resolution with the common panel sizes offered as buttons, and dragging the crop rectangle no longer tracks the pointer at half speed. `pkgrel` returns to 1: a new `pkgver` is a new archive name, so there is nothing left for a release number to disambiguate.

dtourolle	f12aece07e	Make storage pluggable, and prove it with a folder backend ... `RemoteBackend` existed from the first release and bought nothing it was designed for. Seven files in `dr-ui` constructed a `NextcloudBackend` directly, an account *was* a server URL beside a DAV user id, the local cache directory was named after a hostname, and the launch screen knew that signing in meant a browser handshake. The trait was real; the seam was documentation. A trait over operations is only a quarter of it. Pluggable storage needs four things, and this adds the other three: - **Capabilities** — already there, and the reason the engine can drive two backends at the speed each actually runs at. - **Configuration** — `dr_sync::Account`: where a library lives, in whatever form its connector addresses, with no server in it. Loads every existing config unchanged (`backend` defaults to `nextcloud`, `endpoint` is stored under its historical `server` key), and `Account::namespace()` reproduces the old catalog directory byte for byte, because changing it would abandon a catalog, its thumbnail shards, and the sidecars holding unsynced offline work. - **Registration** — `BackendProvider` and `BackendRegistry`. `ui/dr-ui/src/remote.rs` is now the only file above `dr-sync` that names a connector. `Connection` (an account plus an optional `Secret`) replaces the credentials-and-user-id pair that was threaded through fifteen signatures in an order that could be swapped. `Secret`'s inner string is reachable only through `expose()` and its `Debug` prints `Secret(***)`, so the indirect leak — a `{:?}` on anything holding one — no longer compiles into a leak. Nextcloud is unchanged and keeps every peculiarity: propagating ETags, chunked upload v2, `oc:fileid`, the `oc:permissions` probe on a refused PUT, the 423 retry classification, Login Flow v2. Those are what the capability model exists to serve, not something to hide. `dr-sync-folder` is the second connector: a local disk, a network mount, an external drive, or a folder a Nextcloud client already syncs. No account, no credential — the route that works where no secrets daemon does. It declares `LocalEtags` rather than claiming propagation a POSIX directory cannot provide, which costs nothing because 50k `stat` calls are not 50k PROPFINDs. Identity is a path hash, not an inode: an inode survives a rename but differs between devices and is reused after a delete, so two machines would disagree about which photograph a thumbnail belonged to. Re-deriving a thumbnail is a cost; showing the wrong one is a bug. docs/storage.md is the contract — the traits, the four steps to add a backend, and what each connector declares. ARCH §8.0 and §8.4a, and FR-NC-13, say why.	2026-08-29 09:57:52 +02:00
dtourolleandClaude Opus 5	e997be8c72	Say which version this is: 0.8.0 ... A hundred commits since 0.7.0, and the face subsystem in them is not a set of fixes — it is the difference between a feature that was shipped and one that works. Clustering finished at all for the first time: the old agglomeration rescanned every live pair and recomputed average link from scratch after every merge, and on a real library it did not return. A sparse above-threshold graph, connected components and Lance-Williams sums put 1,813 faces at 0.28s, and the merge threshold moved to 0.80 because the old 0.90 was measured — not guessed — to leave a third of the library ungrouped. Faces are no longer indexed at any size or any sharpness. Both floors were measured over the real library with `face_index --quality`: 32 source pixels across the aligned crop, and a contrast-invariant sharpness that catches the large-but-blurred face whose confident, wrong embedding used to weld two people together. The crop is cut once and kept, so the People screen is no longer a derivative of a thumbnail cache entitled to evict anything at any moment. The screen itself became usable: the faces wrap into a grid instead of running off the edge, the header fits a phone, a group can be set aside, and a person's photographs are a button away — as a union or an intersection of several people. And face sync now reaches the other device. Re-indexed images re-export, shards written before the crop and index-time columns are repaired rather than failing every insert, people and the user's judgements about them cross the wire at all, and the pass says what it is doing while it does it. The Android versionCode follows without being restated — package.sh packs MAJOR*10000 + MINOR*100 + PATCH, so 0.8.0 is 800, above the 700 already on devices and therefore an upgrade rather than a refusal. `pkgrel` returns to 1, since this is a new version rather than a rebuild of the last one.

dtourolleandClaude Opus 5	e4875498ca	Ask the platform what colour the screen actually is ... FR-DSP-8's acquisition half. `dr_plat::display` surveys the session's displays and reduces each one's profile to an output space the pipeline can encode into, stating the mechanism per display server as FR-PLAT-LIN-2 requires: - X11 reads the `_ICC_PROFILE` / `_ICC_PROFILE_<n>` root-window properties, enumerating and numbering the outputs through RandR, which also yields the rectangles a window move is measured against. - Wayland binds `wp_color_manager_v1` and asks each `wl_output` for its image description, accepting either an ICC profile on a file descriptor or primaries stated as chromaticities. - Where neither answers, sRGB is assumed and the reason travels with it as data rather than into a log, so the About page can say which path the session is on. A display profile is a measurement of one panel and is none of the four spaces the pipeline knows. Rather than grow an ICC engine, the profile is reduced to D50-adapted colorants and matched against the four; a match that is merely nearest is marked as such and shown as such. Verified on this machine: mutter 50 advertises the colour-management global and reports eDP-1 as sRGB, and the same session forced onto X11 enumerates the output through RandR and correctly finds no atom.

dtourolleandClaude Opus 5	72410f39c6	Answer M1: tract loads both face graphs once their dims are pinned ... Neither InsightFace export parses as shipped -- SCRFD fails at its input node, ArcFace at the first Conv -- which is the same wall dr-segment hit on YOLO's dynamic export. Both load cleanly with the input dims frozen, so the pure-Rust runtime holds for the face pipeline too. tools/fix-face-model-shapes.sh does the freezing, and exists so the artefact is reproducible rather than a binary someone once produced. It takes two forms because the two graphs need different ones: ArcFace's batch is a named dim_param, SCRFD's H and W are dynamic but unnamed. Also notes YuNet loading with no intervention, which matters for the licence question in faces.md 2.3. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-26 19:51:02 +02:00
dtourolleandClaude Opus 5	f82c69bc6b	Say which version this is: 0.7.0 ... Film simulation is a feature, not a fix: five Ilford stocks, a grain model that counts silver rather than adding noise, and the pipeline and UI to drive them. 0.6.0 was tagged thirty-one commits ago and does not describe any of that. The Android versionCode follows from this without being restated -- package.sh packs MAJOR*10000 + MINOR*100 + PATCH, so 0.7.0 is 700, above the 600 already installed on devices and therefore an upgrade rather than a refusal.

dtourolleandClaude Opus 5	b6a95e1965	Simulate a film stock from its measurements, not from someone's grade ... FR-DEV-3f asks for look emulation and proposes HaldCLUT import to inherit the free film-simulation ecosystem. This takes the other road for the stocks where the measurements exist: run the physics. A stock here is its manufacturer's own datasheet -- spectral sensitivity, characteristic curves, dye densities. Light exposes three emulsion layers, the layers develop to densities, the densities are dyes that absorb, and what is left is what reaches the eye. A colour negative comes out orange and upside down because that is what a colour negative is; it becomes a photograph when a paper profile prints it, with the enlarger's filtration solved rather than dialled. What that buys over a LUT is that the parameters stay physical. Opening up a stop moves the picture along the film's real characteristic curve, shoulder and all, instead of scaling a number baked at one exposure. The data cost runs the other way too: a stock is 17 kB of published measurements where one HaldCLUT is 800 kB of one person's grade. It looks like it needs a spectral integration per pixel. It does not, and that is the whole design: - Exposure is a 3x3 matrix. The reconstructed scene spectrum is linear in the sRGB triple, so the integral collapses into nine numbers, exactly -- no approximation. - The characteristic curve is three 1D functions, sampled exactly. - Everything after that -- dye absorption, the print through the negative, the paper, the viewing illuminant, the adaptation -- takes exactly three numbers in, so it bakes into one 32^3 lookup. Per pixel: a matrix multiply, three curve taps, one fetch. Splitting the curve out of the 3D lookup rather than baking one LUT over exposure is measured, not assumed: the curve carries the sharp shape and the dye mixing is smooth, so folding them together would need three times the resolution for the same error. At 32^3 the worst error is 0.003 in linear sRGB, under one 8-bit code value, and a test says so. No wgpu dependency, deliberately, and the same isolation argument dr-lens makes: the model is plain f32 with a documented layout, so every property worth asserting is asserted on the CPU. Binding it to a texture is dr-gpu's job and is not done here yet. The expected values in tests/ came from a Python prototype running against a different colour-science stack. Agreement to three decimals is evidence about the model rather than about one implementation of it -- a transposed matrix or a mispasted observer row would pass every unit test and fail that one. Profiles are converted from spektrafilm by Andrea Volpato, CC BY-SA 4.0. The converter is in the tree and runnable, so what was changed from upstream is auditable rather than taken on trust; profiles/CHANGELOG.txt records it, including the one deliberate deviation -- Mallett & Yuksel's 1 kB basis instead of Hanatos's 4 MB table, which costs accuracy at the gamut edge and saves four megabytes.

dtourolleandClaude Opus 5	2a4a48c0fb	Release 0.4.0 ... Not a patch: this carries a data-loss fix and a feature. Collection membership merged on `images.content_hash`, which the schema computes only for import dedup and reconnect — never in a scan. On a synced library it is NULL for every image, so the union matched nothing and the catalog push that follows a merge overwrote whatever the other device had uploaded. Collections arrived named and empty on every device, and each sync destroyed the other's membership. Keyed on `oc:fileid` now, which every scanned image has. Verified on a 23,000-image library: 247 memberships recovered, and a round trip between tablet and desktop confirmed in both directions. Card import (FR-CAT-10, FR-CAT-11, FR-NC-7a, FR-NC-7b) arrives with it: the ingest engine, the write half of the storage abstraction, removable-volume detection, duplicate detection in two tiers, dated folders on both sides, and thumbnails made while the originals are still in hand. Uploads always go to the library on the server; what lands on this machine is a staging copy the app removes once the upload is confirmed, and a move-import empties the card only of photographs the server has acknowledged.

The workspace version has read 0.1.0 since before v0.2.0 was tagged, so every binary built from this tree has reported itself two releases stale.

dtourolleandClaude Opus 5	7d1e6f724e	Import photographs from a card ... Distinct from a scan, and the distinction is the whole reason the crate exists: a scan catalogues files where they already are, where an import moves them from a card into the library. A scan that fails halfway has read nothing; an import that fails halfway has written something. So the failure paths are the design. Bytes stream at 1 MiB and are hashed on the way past, so an 80 MB RAW never sits in memory. The second destination (FR-CAT-10's backup copy) is written from the same read rather than copied from the primary afterwards — a backup made by re-reading the primary would inherit a bad write rather than catch it, and re-reading the card doubles the wear on the one copy that still exists. Verification re-reads the destination, because hashing what is still in memory would pass on a full disk, a dying card and a truncated write alike. Anything that fails past the point of creating the file takes the file back, or the next scan catalogues a truncated RAW as though it were fine. Three things the crate refuses to know. It never deletes from the card: a move-import records what is now redundant and a separate retire() does the deleting, because on a syncing library "safe" means the upload was confirmed (FR-NC-7b). It does not decode, so capture metadata arrives through a probe and a card of unreadable files costs no demosaic. And it does not know what a duplicate is, since that is a catalog query — FR-CAT-11's two tiers arrive as one closure asked twice, once before any transfer and once with the digest. Camera serial would be the stronger metadata key and is absent, because nothing in the tree reads it yet; make and model plus capture time and the original filename is what is available, and the digest tier covers the gap.

dtourolle	0da8271836	Let the model say what a thing is and the watershed say where it ends ... Local masking needs to know where an image's regions are. The watershed spike (S15 arm A) found the boundaries but had no idea what any of them enclosed; its coarse levels were geometric accidents. This adds the other half and the thing that joins them. `core/dr-segment` is where region reasoning now lives — the hierarchy moves out of `dr-gpu`, which keeps only the pixel passes that are genuinely shaders. The new crate is device-free and, without its default features, model-free too: 20 of its tests need neither an adapter nor 11 MB of weights. Arm B runs YOLO26n-seg through `ort`. D13 framed inference as a choice between `ort`'s C++ runtime and the pure-Rust dependency policy; that was a false choice. `ort`'s `alternative-backend` feature unlinks the C entirely and `ort-tract` supplies the API from tract, which is pure Rust. Measured before committing to it: zero unsupported operators, 420 ms for 640x640, and correct masks on bus.jpg. No NDK problem to solve, so D13's largest tolerated exception is not needed. Arm C is `prior.rs`, and it ships because the two arms fail in opposite directions. Instance membership re-weights the merge saddles, so region pairs the model believes share an object merge early and pairs straddling its edge merge late. No boundary moves — only the order in which they dissolve — which is how the result stays pixel-accurate at every level while its coarse levels become named things. Two things the spec assumed that turned out to be false, both recorded in models/LICENCE.md: there is no usable ADE20K-trained YOLO, so the shipped vocabulary is COCO's 80 subjects and *stuff* like sky and foliage must come from arm A; and tract cannot parse a dynamic-shape export, so the graph's input is fixed and tiling is the only route to more semantic resolution. Weights are AGPL-3.0, which GPLv3 §13 permits and which makes the combined work effectively AGPL. Deliberate, not accidental. They live in Git LFS, and a build script fails with an instruction rather than embedding a pointer file when the clone lacks them.	2026-08-22 08:39:16 +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	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.

dtourolle	5dc1279429	Add the Android app shell; cap cross-build parallelism ... Cap both halves of the container build: CARGO_BUILD_JOBS limits how many rustc processes cargo starts, while --cpus limits what the container gets regardless of what nested build scripts spawn — cc, cmake, and ring's asm build all parallelise on their own account and do not consult cargo. Without both, a full cross-compile takes every thread on the host and makes the machine unusable for the length of a background build. Assisted-by: LLM	2026-08-09 21:10:00 +02:00
dtourolle	d6ddd0703b	Add dr-thumbs: a sharded, syncable thumbnail store ... A thumbnail is the one derived artefact worth sending over the wire: it costs a range fetch plus a decode to produce and is identical for every client looking at the same file. A second device that downloads a shard gets a full grid without fetching a byte of RAW. Sharded at 25 MB, filled sequentially. The cap is about sync granularity, not SQLite's limits — one growing database means every client re-downloads it whenever a single thumbnail is added, whereas with sequential fill only the newest shard is ever dirty and sealed shards are safe to cache forever. Stored JPEG-encoded rather than as raw RGBA: a 256px RGBA buffer is ~256 KB against ~20 KB encoded, and that 13x is transfer cost on every client. Keyed on Nextcloud's oc:fileid, stable across server-side rename and move. Assisted-by: LLM	2026-08-09 20:38:12 +02:00
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
