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	ce666c768e	Let a binary name the release it came from ... 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. The cost lands on whoever reads a bug report quoting it: the version names a commit from before either release, and they go looking in the wrong place. Sets the workspace to 0.3.0. The tag stays the release identity; this only makes the tree agree with it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-22 20:54:34 +02:00
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
