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> |

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.

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

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.

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.

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> |

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.

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.

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). |

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. |

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. |
