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 A `Description` left empty once our properties come out of it is withdrawn, which is what keeps a rewrite idempotent instead of adding a husk to the file on every save.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

dtourolleandClaude Opus 5	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	509c3a3e96	Merge: a log that survives the process, so the tablet can be debugged ... Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> # Conflicts: # apps/darkroom-android/Cargo.toml # apps/darkroom-desktop/Cargo.toml # platform/dr-plat/src/lib.rs	2026-08-30 13:46:06 +02:00
dtourolle	465f5a7ffa	Keep the log after the session that produced it ... Everything this application knew about a failure went to stderr on the desktop and to logcat on Android, and both are gone the moment the terminal closes or the ring buffer wraps. That is fine when the person debugging is sitting at the machine. It is useless for the case NFR-OPS-1 actually describes, and the one Android makes normal: somebody reproduces a bug on a tablet, and then sends us a file. A large amount of Android behaviour has never run on a device — image intents read over JNI, an ExportProvider, a class loaded through the activity's class loader, memory-pressure eviction, lost-root recovery — and the single most likely failure of the lot, the activity's loader not resolving our classes from android_main's thread, produces one line that scrolls past. That line is now in a file, with the thread that emitted it named beside it. dr_plat::state answers "where does this platform keep state for this app": $XDG_STATE_HOME/darkroom on Linux, and on Android whatever the entry point declares. Separate from configuration and from the catalog for the reason XDG separates them — state is the thing nobody backs up and the user may delete without consequence. dr_plat::diagnostics is the sink. Two files of 4 MiB, so the worst case is a number rather than a discovery on a full phone; one line per write with no BufWriter anywhere, because on Android processes are killed rather than ended and a buffered log loses exactly the line it was kept for; and redaction applied at the sink rather than at the call sites, since a rule every author has to remember is not a rule. It tees the platform's own logger rather than replacing it, so logcat is unchanged — losing that while debugging would have made this a downgrade. Android logs to external_data_path, not internal. Both are app-private and both survive backgrounding; what separates them is that /data/data/<pkg>/files needs run-as against a debuggable build to read and /sdcard/Android/data/<pkg>/files is a plain adb pull from any build. A log nobody can retrieve is not a diagnostic. The consequence is that anyone holding the tablet can read it, which is why the redaction is where it is, and why configuration stays on internal_data_path. What is redacted is what NFR-SEC-2 and NFR-OPS-1 name: credentials and tokens, found by the keyword that nearly always sits next to them, plus the two forms that carry one with no keyword at all — an Authorization scheme and a URL's userinfo. What is deliberately not redacted is filesystem paths and the names of the user's photographs. They are in neither requirement's list, and "failed to decode <redacted>" is not a diagnostic; the preview-and-consent step NFR-OPS-1 asks for governs those better than scrubbing would, because it lets the user look. The over-redaction failure is tested as carefully as the under-redaction one. A scrubber that eats "using basic sRGB as the fallback" makes a log useless without ever being caught.	2026-08-30 10:40:54 +02:00
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	c57fd8ec5a	Merge: compile our own Java into the APK, and answer an image intent ... The APK carried no Java of its own -- the only dex in it was Slint's -- which blocked FR-PLAT-AND-4's foreground service and FR-PLAT-AND-6's outbound half alike. assemble-apk.sh now compiles everything under android/java against android.jar and has d8 merge it with Slint's dex into one classes.dex. With no .java in the tree the step is skipped and the APK is byte-for-byte what it was. -source 8 -target 8 -bootclasspath android.jar is load-bearing: from -target 9 javac rejects -bootclasspath, platform classes then come from the JDK instead of android.jar, and the build stays green while the device raises NoClassDefFoundError. FR-PLAT-AND-6 with it: VIEW, SEND and SEND_MULTIPLE filters, the launch Intent read over JNI before Slint is given the app, and a hand-written ExportProvider rooted at getFilesDir() rather than AndroidX FileProvider, which would have meant Gradle. singleTask, because the new filters let another app launch the activity while it runs and the default mode would start a second android_main, Slint backend and wgpu device in one process. Classes load through the activity's loader; FindClass on android_main's thread sees only the system loader. The share half has no caller yet and is deliberately untagged. The five tests read the manifest and the Java through include_str!, so they fail if a filter goes, if the activity stops being singleTask, if the provider becomes exported, or if the authority and the class drift apart. Verified: javac, d8 and a real dex merge run against the host SDK; aapt2 link over the manifest; clippy -D warnings clean; 5 tests pass. Not verified: anything needing a device.

dtourolleandClaude Opus 5	09dddde594	Take the photograph another app hands over, and hand an export back ... FR-PLAT-AND-6 asks for two things this app did neither of: be a receiver for image view and share intents, and share exported results out through a FileProvider. The manifest declared one activity with one MAIN/LAUNCHER filter, so nothing on the device ever offered DarkRoom for a photograph, and there was no route out at all — Android has refused file:// URIs between apps since API 24, and a content:// URI needs a provider to be behind it. Inbound. Three filters now: VIEW for a gallery or a file manager, SEND and SEND_MULTIPLE for the share sheet, all on image/*. `android_main` reads the launch Intent before it gives `app` away to Slint, and what comes back is passed to `dr_ui::run` exactly as argv is on the desktop — `startup_action` already treats a non-empty list as "the user asked for these specifically", which is what a share is. The URIs are copied into the cache before the viewer opens, and that cost is real: a shared raw file is written once, in full, on the startup path. A content:// URI is a handle into another app's provider, not a path, and the decoders take paths; the alternative is teaching the whole read path about URIs, which is FR-PLAT-AND-1's SAF connector and is not built. Outbound. ExportProvider serves one directory — getFilesDir(), which is the same path `internal_data_path` gives the Rust side — and refuses everything else by canonicalising the request and checking it is inside that root, so `../` and a planted symlink fail the same test. Not AndroidX's FileProvider, because AndroidX is a Maven artefact and this build has no resolver; what it does is a hundred lines and they are here. The share half has no caller. The provider, the URI grant and the chooser are all in place, but the control that would invoke them belongs in `ui/dr-ui`, and wiring it needs an `AndroidApp` the interface can reach. It is documented as unwired and deliberately not tagged as covering the requirement. `launchMode="singleTask"` comes with the filters and is not decoration: another app can now launch this activity while it is running, and the default mode answers that by creating a second NativeActivity in the same process — a second android_main, a second Slint backend, a second wgpu device. The cost of the fix is stated in the manifest: a share arriving while DarkRoom is already open brings it forward without opening the image, because onNewIntent has no route through android-activity's event stream. The Java is Java because Android constructs it: a ContentProvider is instantiated by the system from its manifest entry, and getIntent() exists only on an activity object. Both directions live there rather than in JNI so that what crosses the boundary is two method signatures instead of forty, each of which is a string checked at run time and nowhere else. What a test can hold: the declarations. Nothing about an Intent or a ContentProvider is reachable from `cargo test`, but an intent filter that is deleted takes the app out of every "open with" menu silently, and an authority that stops matching its class raises a SecurityException inside somebody else's app. The tests in lib.rs read the manifest and ExportProvider.java through `include_str!` and hold both to that, on the host, which is the only place in the workspace that looks at either file from Rust.

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	21d599b420	Test the guard, since the bug was a branch nobody ran ... The catalog clobber existed because `if let Ok(bytes)` had a failure arm that was never exercised. Fixing it without covering that arm leaves the next person free to collapse it back. Three tests against a backend whose read fails in a chosen way, counting writes — because what went wrong was not a wrong value but a write that should not have happened at all: - a dehydrated snapshot uploads nothing - an unreadable one uploads nothing either, since "refused" is no more "absent" than "not downloaded" is - and a genuine first sync still uploads, which is the half that keeps `NotFound` distinct from `NotMaterialised` rather than merely cautious Checked against the original shape: the first two fail on it and the third passes. A guard test that cannot tell the bug from the fix is decoration. `async-trait` joins dev-dependencies to stand the double up behind `dyn RemoteBackend`.	2026-08-29 10:40:38 +02:00
dtourolle	c102ba9df2	Treat a placeholder as the photograph, not as a one-byte file ... The folder connector was pointed at a Nextcloud VFS tree and got three things wrong, the first of which loses work. **A dehydrated sidecar read as absent.** `a.drsc` does not exist when the client has dehydrated it — only `a.drsc.nextcloud` does — so `get` missed, `.ok()` swallowed the `NotFound`, and the sidecar writer took that for "there is no sidecar yet" and wrote a fresh document over the existing one. Every edit another device had put there went with it. That function's own doc comment calls this the exact loss the format's unknown-key preservation exists to prevent. **A stub was catalogued as a 1-byte image**, and ARCH §9.0 measured this machine at 121,785 placeholders against 10,267 real files — so a folder library on a synced tree was ~92% broken rows. **Identity changed on hydration**, so downloading a photograph looked like a delete and an add, orphaning its thumbnail and its face rows. Entries now carry the photograph's own name and a `materialised` flag; `get` on a stub returns the new `RemoteError::NotMaterialised`, which is distinct from `NotFound` precisely because the sidecar writer must treat them differently — it fetches the sidecar and merges, or leaves the entry queued. Hydration is a **borrow**. `BorrowPool` records what was on disk before it asked, so `release_all` dehydrates only what a pass brought and leaves what the user already had. Reference counted: the thumbnail pass and the face pass meet on the same RAW, and without counting the first to finish dehydrates the file the second is reading. A borrow against a plain folder or a server does nothing, so a pass written for VFS runs everywhere. Releasing means asking the client to dehydrate and never deleting: a deletion inside a synced tree propagates to the server and removes the photograph from every device. Not a second backend — the capability is per *connection*, not per type, since the same folder hydrates only while the client runs. The convention arrives through a detector the registry supplies, so `dr-sync-folder` still knows nothing about any client's protocol. ARCH §9.0a records this as an amendment: finding 3 rejected hydration because it costs 100× a range read, and that comparison assumed a connector was available. A folder library has none.	2026-08-29 09:57:52 +02:00
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	96d07da15f	Sync face data as sealed shards, so a second device does not re-index ... Indexing 23,500 images is about two hours of CPU, and the result is byte-identical on every device: the same model over the same proxy produces the same embedding. Paying for it once per account rather than once per device is the point. Shards rather than the catalog snapshot, because the snapshot goes up whole on every sync and a fully indexed library carries roughly 30 MB of embeddings. That is exactly the cost the thumbnail store's 25 MB cap exists to bound, so face shards use the same cap -- imported from dr_thumbs rather than restated, since the number is a statement about sync cost and the two must not drift apart. The split follows the one already there: bulk immutable data in sealed shards, small mutable data in the catalog snapshot. Faces, landmarks, embeddings and run markers shard; people, names and assignments ride the catalog and merge by uuid. Keyed on oc:fileid throughout, never on image_id, because a row id means nothing on another device. The run marker travels with the faces it describes. Without it a receiving device cannot tell an image with no faces from one never examined, and would re-detect every landscape it had just adopted.

dtourolleandClaude Opus 5	26a1eb7e28	Record that face detection has run, not just what it found ... An image with no faces in it was indistinguishable from one that had never been looked at, so every landscape, still life and document scan in the library was re-detected on every pass, for ever. In a real library that is most of it: on the 23,527-image test library, 64 of the first 110 images indexed contain no face at all. Schema v9 adds face_index, a run marker per (image, model) carrying the face count and the proxy edge it read. Keyed on the model, so a model change puts every image back in the queue by itself. That makes a coverage figure possible, which is the thing a user actually wants to see. The audit also splits the outstanding set by whether a proxy exists, because 23,417 awaiting a proxy and 110 ready to index are different problems, and telling the user to run indexing again would not fix the first. The Identity screen gains Index faces, Stop, and the coverage line. examples/face_index.rs is the same check and sweep without a window, which is the right shape for an overnight pass. Measured on the real library in release: 3.5 images/second, 110 images and 125 faces in 30 seconds, and a second run correctly finds nothing left to do.

dtourolleandClaude Opus 5	2ac069a6b3	Index the library's faces, and group them into people ... Wires dr-face to dr-catalog: a background sweep that reads the proxy the grid already built, detects, aligns, embeds and stores, then a clustering pass that turns those embeddings into suggested people. Detection runs on the Large thumbnail tier and nowhere else. That is what makes the feature affordable -- a browsed library has already paid for its proxies, so face indexing adds no RAW decode that was not already happening -- and it is why an image whose proxy is missing is skipped rather than fetched: requesting one here would put face indexing on the network path FR-CULL-8 keeps it off. The sweep keeps no cursor. It asks the catalog what is missing, so it resumes after process death with no repeated work beyond the in-flight image, and cancelling is dropping the receiver. recluster writes only the suggested half. Confirmed faces go in as anchors and come back untouched, and a cluster of one stays nameless -- naming every stray face would fill the People view with noise the user then has to dismiss.

dtourolleandClaude Opus 5	00e78dc2ac	Cluster faces into people, and calibrate what a similarity means ... FR-CULL-9 forbids thresholding a bare cosine anywhere in the subsystem, so calibrate fits P(same person) per library and reports whether the fit is trustworthy. Two details carry most of the weight. The fit runs against a 200-bin histogram rather than a pair list: a 25,000-face library has ~3e8 pairs and no gradient descent is running over that. And a fresh library has no valid calibration, because the positives have to come from user confirmations or burst siblings -- bootstrapping them from high cosine would fit the calibration to the belief it was supposed to test. Clustering defends against the over-merging FR-CULL-10 warns about with constraints rather than a better threshold: two faces in one photograph never merge, and two groups confirmed as different people never merge. Average link rather than single link, so one strong edge cannot weld two families together. Calibration is defined once, in dr-face, and dr-catalog re-exports it. Two implementations of one probability model is exactly how a number comes to mean the wrong thing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-26 20:10:33 +02:00
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	baa8957e80	Let a photographer choose the film, and remember which one ... The stock model rendered correctly and nothing could ask for it. This is the picker, and the sidecar key that makes the choice outlive the session. How the choice persists was the open question, and the answer was already written down twice in sidecar.rs: `rating` is a top-level key "because a rating is not an edit", and `masks` are one "because a layer is not a scalar". A stock is that kind of thing -- a choice of material, not a number a slider moves -- so it is a top-level key too. It stores the **id**, not an index. Stocks are files that users add, so an index would mean installing a profile silently changed which film every existing photograph had been developed on. A name this build has no profile for still round-trips untouched, because the alternative is that syncing to an older phone quietly un-develops the picture. Only the names travel. Turning one back into tables needs the profile database, which dr-pipeline deliberately does not link, so `Version::apply` clears the film and the session re-bakes -- after the parameters, because the bake reads the film's own exposure sliders and the print balance is solved against them. That is also why moving those sliders rebuilds the lookup where no other control in the panel does: an enlarger's filtration depends on how the negative was exposed. The panel keeps its rule. It still names no operation and still generates every control from a declared parameter kind; the stock gets a bespoke control beside those, exactly as the mask stack does, and for the same reason. The film's exposure and print exposure arrive as ordinary generated sliders. Two defaults worth stating. Picking a colour negative prints it, because an unprinted one is an orange strip and offering that as the first thing somebody sees after choosing Portra reads as a bug rather than as a choice -- the toggle is there for anyone who wants the scan. And a paste carries no film: a preset is a parameter map, and a stock is not a parameter, so pasting one would paste a choice the clipboard never took.

dtourolleandClaude Opus 5	4a2fcb6d22	Render a film stock on the GPU, and let it take over the rendering ... The stock model landed in dr-film with no way to see it. This is the pipeline node, the two texture bindings it reads, and the end-to-end test that proves the shader agrees with the model. The design point is that a film simulation is not an adjustment. Every other node changes a picture; this one makes it. A stock's characteristic curve does the camera profile's base curve's job -- from measurements rather than from a curve somebody drew -- so running both renders the scene twice: the camera's rendering, and then a film's rendering of that. It looks like neither, and it reads as a colour-management bug with no colour-management bug to find. So `Operation::renders` is new. A node declaring it takes camera RGB and hands back linear sRGB, and the composer emits neither the base curve nor the conversion out of camera space. Both halves move together, and the composer keeps them as one string precisely so that getting half of it right is impossible. The tables are not parameters, for the reason vignetting's coefficients are not: they are measurements. dr-pipeline declares the layout as a plain struct and keeps its no-dependency property; the two crates share no types on purpose. `EditGraph::set_film_tables` offers them to every node rather than to the one that wants them, because knowing which concrete type is which is what the graph is organised not to know. Bindings 4 and 5 follow the masks precedent: declared unconditionally so one bind group layout serves every generated shader, bound to 1x1 placeholders when no stock is loaded. Both are interpolated by hand with textureLoad -- this pipeline binds no sampler, and adding one for two lookups would cost a binding in every shader. Uploads are keyed on content so an unchanged stock does not push half a megabyte across the bus per frame. The end-to-end test earned its place immediately: it found the density lookup being filled z-fastest while a 3D texture upload wants x-fastest, so the red and blue axes were transposed. Green matched exactly, which is what that bug looks like -- a plausible photograph of the wrong colour, and one that every unit test on either side of the seam passes. dr-film now pins the layout in a test that needs no device, and states it where the field is declared.

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.

dtourolleandClaude Opus 5	743fefe7f1	Render each body through the profile its own files describe ... Colour came from whichever matrix rawler happened to key `D65`, the second one was discarded, and the rendering was left linear. That is the dcraw default, and FR-DEV-3e names it as the reason people abandon a converter in the first hour: correct in the abstract, flat and poor on skin in practice. The decoder now builds a camera profile. - `ColorMatrix1/2` and `CalibrationIlluminant1/2`. rawler surfaces these as an illuminant-keyed map — for DNGs from the tags, and for native formats from its own camera database — so a Canon CR2 arrives with a tungsten matrix and a daylight matrix exactly as an Adobe DNG of the same frame would. Dual-illuminant support is therefore not a DNG feature here. - `ForwardMatrix1/2`, read straight from the root IFD, because rawler parses them and never surfaces them. Where a file carries both, they replace the inverted colour matrix: the same relationship measured in the direction rendering actually wants, rather than an inversion that amplifies the measurement error exactly where skin lives. - `AsShotNeutral`, used to estimate what the scene was lit by and to interpolate between the two calibrations in mireds. The estimate is circular — the temperature needs a matrix and the matrix needs the temperature — so it is a fixed point, three rounds, as Adobe's SDK does it. Bodies calibrated at neither D65 nor A stopped rendering uncalibrated as a side effect: a Phase One IQ3 carries D55 and D75 and used to get no matrix at all. And a base curve, applied per channel in camera RGB between the last adjustment and the conversion out of camera space — a toe, a steep midtone and a shoulder, which is the difference between a photograph and a scan of one. It is not an edit: no slider, nothing in the sidecar, because it belongs to the body rather than to anything anyone decided, and a sidecar is shared between bodies. It is not a develop node either, and `ops/README.md` now records why. It evaluates on the tone curve's own spline rather than a second copy, so a profile author placing a control point and a photographer dragging one mean the same thing by it. The curves are data. `core/dr-decode/profiles/base_curves.yaml` ships inside the binary as a floor and is superseded by any copy on disk carrying a higher `version:`, so a body can be added and distributed without a release — and, under the GPL, contributed. The comparison runs both ways: a stale pack cannot hold an upgraded binary back at last year's rendering. Canon EOS 6D and R6, Nikon Z 6 and D750, Sony A7 III and Fujifilm X-T3 ship with their own curves. Every other body gets a conservative default, which is much closer to right than the identity is for any of them. A JPEG gets none — it has already been rendered once, by the camera.

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	5ecb35864f	Put the region map behind the sliders that were already there ... A mask layer holds a real develop chain, so the develop panel can edit one with no new controls: select a layer and the same sliders read and write its chain instead of the graph's. An operation declared in `ops/` tomorrow becomes locally adjustable by existing, which is the payoff for making a layer a chain rather than a handful of special-cased parameters. `segmentation.rs` joins the two arms into the one thing the view needs. The model reads the image through a neutral graph rather than the edited one, so a segmentation survives an exposure change instead of being invalidated by every slider. Arm B failing is not fatal: a missing or unreadable model leaves a working watershed map, because refusing to segment at all would trade a working feature for a strict one. The overlay colours groups by a golden-angle walk over hue. Deterministic rather than random, so a region keeps its colour across a level change and the eye can track it; boundaries drawn black over the fill, because two adjacent groups landing on near hues read as one region and telling them apart is the whole reason to look at it. Clicking the photograph creates the layer if none is selected — that is how a local adjustment begins, and making the user press "add layer" first would be a step with no decision in it. Shift-click extends, and clicking a region already selected removes it, so one gesture both adds and corrects. `segment-readback` is a new dr-gpu feature and not a loosening of `readback`. The region-graph transfer is once per image on a worker; the one AC-8 forbids is per frame in the render loop. Sharing a switch would have forced a build wanting local masking to unlock the other. F3 still stands and the feature name says so.	2026-08-22 08:39:17 +02:00
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.

dtourolleandClaude Opus 5	cf8f5b632f	Show the develop frame itself, instead of a photocopy of it ... The oldest open item in the project (ARCH §6.1, spike S1, AC-8). Every frame in develop was read off the GPU into a `SharedPixelBuffer` and handed back to Slint to upload again: ~7 ms at 4K against a 0.28 ms compute pass, 96% of the frame spent carrying pixels to the CPU and back so they could be drawn where they already were. Slint 1.17 will adopt a `wgpu::Texture` directly, and the whole of what that needs is arrangement rather than code. **One device, made before the window.** A texture belongs to the device that allocated it, so the compute passes and the compositor cannot each open their own. `GpuContext::new_shared` opens one and hands back the instance and adapter alongside it; `dr_ui::shared_gpu` gives all four to `BackendSelector::require_wgpu_29(WGPUConfiguration::Manual { .. })`. That call has to come before the first window, because creating one selects a backend for you — which is why the GPU is now opened at the top of `run` rather than two hundred lines down beside the other controllers. dr-gpu still names no UI type. It hands out raw wgpu and does not ask who is compositing (ARCH §6.5a). **Vulkan only on the shared path**, where headless keeps its GL fallback. wgpu's GL backend reaches its display through EGL at instance creation, and before a window exists there is no display handle to give it — so a GL instance cannot later produce the window surface Slint needs from it. A machine with no Vulkan gets no shared device and browses without develop, which is the same degradation as no adapter at all. **`renderer-femtovg` becomes `renderer-femtovg-wgpu`.** The old one is FemtoVG over OpenGL and cannot be handed a wgpu texture at all. It is not kept alongside as a fallback: FemtoVG-over-GL has no branch for an imported texture, falls through to "render this image into a buffer", gets nothing, and draws nothing — a blank canvas with no error, which is worse than the failure it would be papering over. The consequence is stated plainly in the manifest: the desktop app now needs a working wgpu adapter to open a window. **Two output textures, not one, and this is the part that is not obvious.** Slint repaints when the image property *changes*, and it decides that with `PartialEq` — which for two images over the same `wgpu::Texture` says "unchanged". A pass that reused a single target would have rendered every slider move correctly on the GPU and shown none of them: right, and invisible. `AdjustPass` alternates between two targets, so consecutive frames are genuinely different values. It also settles the read-while-write question that one queue was already answering. `RENDER_ATTACHMENT` is added to both render targets. Neither pass uses it; Slint rejects an imported texture without it, on the reasoning that a compositor handed a texture may need to draw into it. **`AdjustPass::read_output` is deleted rather than gated.** It and `export_pixels` were the same transfer under two names, and the comments explaining why they were separate are the point of the whole criterion: reading pixels back to *display* them is the defect, reading them back to *encode a file* is the only way a file is made. The display twin is now gone outright, which is stronger than a feature flag — it cannot be turned back on. `export_pixels` is untouched and still ungated. The `readback` feature comes off dr-ui, darkroom-desktop and darkroom-android; it stays in dr-gpu, where it still gates `RenderTarget::read_pixels` and the segmentation field readback. `examples/develop` moves to `export_pixels`, which is honest — it writes a PPM — and so no longer needs the feature. Four tests, each named for what it protects and each of which fails without a screen if the property it guards breaks: - the adjust target satisfies every condition Slint's import checks, asserted in the crate that owns the descriptor, because a descriptor that drifts fails at runtime on a real display and nothing else would notice; - consecutive renders are different textures, and the third is the first again, so the alternation is a rotation and not an allocation per frame; - the develop canvas has no CPU pixel buffer and does have a wgpu texture — AC-8 itself, in the terms Slint uses; - consecutive frames compare unequal as `slint::Image`, which is the property the repaint actually depends on. The zoom test's readback moves into the test module. It has to: there is no library function that copies a displayed frame to the CPU any more, and that is the point — the round-trip now exists in the test binary and nowhere a shipping build can reach. **What is not proven.** No GUI was run. What is verified is that the texture satisfies the import contract, that the import succeeds, that the canvas is a texture rather than a buffer, and that consecutive frames are distinguishable. What is unverified is everything that needs a display: that Slint's FemtoVG wgpu renderer adopts the Manual configuration on a real surface, that the picture appears the right way up and the right colour, and the frame timing that motivated the whole exercise. Android is untouched by testing — the android backend routes a WGPU29 request to Skia, whose wgpu surface does handle imported textures, but that is read from the source, not observed. 56 dr-gpu tests and 255 dr-ui tests pass, clippy clean under `-D warnings`, fmt clean.

dtourolleandClaude Opus 5	bb71f141e7	Let a folder on this machine be scanned into the catalog ... `dr_catalog::scan` has known since it was written what a changed directory means — when to prune, when to list, and the one question that decides whether a deletion sweep is safe. It was fully tested and nothing called it, because walking a real directory "belongs to the platform layer" and the platform layer was eleven lines re-exporting `secrets`. So every photograph in DarkRoom arrived over WebDAV, and a user without a Nextcloud account saw nothing at all. This is the missing half: a `Storage` trait, a filesystem implementation of it, and the driver that pours one into the other. The trait is shaped by the platform it does *not* yet support. Android's SAF gives no filesystem path, which is why `SourceRef` exists; less obviously, it gives no way to *compose* one either — a document id is opaque, and the only way to learn a child's id is the children query that returned it. So a listing hands back the reference to each entry rather than a name for the caller to join onto a parent, and there is deliberately no "path + name" helper anywhere above `LocalStorage`. That single restriction is what makes SAF a second implementation rather than a second set of call sites. A reference is otherwise an opaque `(RootId, key)` pair the catalog stores verbatim and rebuilds later, which a persisted tree grant supports exactly as a relative path does. A `Path` now appears in one place: `LocalStorage::grant`, where the folder the user picked is handed in. Everything above it addresses a `RootId`. `dr_catalog::walk` is the seam. It probes a directory, asks `scan` what that means, lists only when told to, and reconciles what it found against the rows it holds. Two things it does are worth saying out loud, because both are ways to lose a library: Absence only counts where absence was observed. A listed folder proves its missing images are gone; a pruned one proves nothing about its contents, and a scan that was cancelled or that failed part-way proves nothing about folders it never reached. So the file sweep runs per listed folder, the folder sweep runs once at the end and only after a complete scan, and a root that cannot be reached at all marks its images offline and deletes nothing — FR-CAT-9's line between proven-absent and merely-unreachable, which is the difference between unplugging a drive and losing everything on it. A trashed image is absent from its folder on purpose. It is exempt from both sweeps, and detached from a folder about to be deleted rather than cascaded away with it, or a soft delete would come undone the first time the folder it came from was rescanned. Two things the tests taught, both changes to what was there before: Modification times are now milliseconds, not seconds. Change detection asks whether a timestamp moved, so the unit's granularity is the width of the window in which a change is invisible — and a second is long enough to copy a card and start a scan. The test that caught it looked like a test bug; it was not. SAF reports milliseconds natively, so this is also the unit that needs no conversion on the platform with the coarser clock. And an in-place rewrite of an existing file is invisible to directory-level pruning, because writing to a file moves neither its directory's mtime nor its entry count. That is a real limit, now documented and held by a test rather than left to be discovered. It bites less than it reads: an export, a restore, `mv`, and every editor that saves safely write beside the file and rename over it, which does move both. Narrowing the format filter no longer deletes what it stops matching, which fell out of the same principle: unticking JPEG says stop looking for new ones, not discard the hundred already rated. The files are sitting right there. `DirState` and `DirEntry` move to `dr-types`. They are the sentence the platform says to the catalog and both crates need the same one; `scan` re-exports them so nothing that used them has changed. Not done: the UI. The launch screen's "Open library" flow is account-shaped from the first field to the thumbnail worker, and giving it a local branch is its own piece of work rather than a button. `cargo run -p dr-catalog --example scan_local -- ~/Pictures` scans a real folder and reports what it cost; run it twice to see the second run list nothing.

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	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	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	8b7c1e7f10	Open the sign-in URL through an ACTION_VIEW Intent on Android ... The previous commit made the missing launcher honest; this gives Android a real one, so Login Flow v2 can complete on device. Builds `new Intent(ACTION_VIEW, Uri.parse(url))` and hands it to `startActivity` over JNI. The JavaVM and Activity come from ndk_context, which android-activity's glue populates at startup — the same handle Slint's backend uses, so there is no second VM to reconcile. The login worker is a plain std::thread and therefore unknown to the JVM, where any JNI call would abort the process. jni 0.22 scopes attachment to a closure rather than returning a guard, so the whole Intent is built and dispatched inside `attach_current_thread` and the thread detaches on the way out. Names use `jni_str!` and signatures `jni_sig!`, both compile-time: a typo is a build error rather than a NoSuchMethodError on the device. A pending Java exception is checked and cleared before returning, since leaving one pending makes the next JNI call fail somewhere unrelated; in practice it means ActivityNotFoundException, i.e. no browser installed. jni is pinned to 0.22 to match Slint's Android backend.

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.

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
