Run the library from local data when the server is unreachable
Also carries in-flight work that shared these files: the zoom structure-key fix in the adjust pipeline, nearest-neighbour filtering past 1:1, the timeline scrub marker correction, the 423-Locked retry in the metadata sweep, and the thumbnail size-class migration. # Offline mode (FR-CAT-9) The app previously assumed the server was reachable and treated its absence as a series of unrelated per-operation failures. A launch without a connection produced an empty grid, even with a complete catalog on disk and every thumbnail already in the shards. Reachability is now inferred from traffic the app was already making, rather than probed for. `RemoteError::indicates_offline` draws the line that makes this possible: a dead connection is offline, a 403 or a 500 is not — the server answered, so blanking the library over one forbidden file would be a worse error than the one being reported. `Reachability` turns those outcomes into a state, so a library browsing happily never issues a probe at all. Going offline takes one failure, because the user is already experiencing it. Coming back requires evidence — a completed scan or a fetched thumbnail — with a capped exponential backoff behind the manual retry, so twelve sweep lanes failing together do not schedule twelve immediate probes. What keeps working: the catalog opens even when the scan that normally provides it failed, so the grid fills from the last successful scan. Thumbnails come from the shards. Rating, flagging and collecting are catalog writes that never touched the network. What stops is opening an original that was never stored locally, and it now says so in those words instead of reporting "network error: connection refused" over a photograph. Work that is pure network is refused rather than left to fail slowly: the metadata sweep, derived sync, and sidecar writes. The sweep would otherwise spend a timeout per image across the whole library while the progress bar implied something was happening. Deferring sidecars is a real gap rather than a hidden one — a rating made offline reaches its sidecar only when that image is judged again while connected — and it is recorded as such at the call site. # The "On this device" filter A chip beside the rating filters, narrowing the grid to images whose original is held locally. It composes with the rating terms rather than replacing them, so "five-star frames I can actually edit on this train" is one filter. The predicate is SQL, like the rating terms and for the same reason: the count in the header has to agree with the cells drawn. It reads `image_cache.tier_actual`, which nothing writes yet — the next commit fills it. Until then the chip honestly reports zero. `Tier` gains an explicit on-disk encoding. The variants are ordered by generosity and the derived `Ord` invites reordering them, which would silently reinterpret every cached row; the round-trip test is what holds the two in agreement.

Add remote move and mkdir; distinguish 403 from 401
Soft delete needs to move a photograph into the trash folder and back, and the stable id must survive the trip. WebDAV MOVE is one request and preserves oc:fileid; a copy-then-delete would allocate a new one, orphaning the thumbnail shard entry and the sidecar mapping and turning a restore into a full re-download. Overwrite: F, because a header that permits overwriting is one that eventually does. create_dir does MKCOL outermost-first and treats 405 — Nextcloud's answer for an existing collection — as the goal state rather than an error. Nothing else creates the trash folder, so without it the first trashed image of every library fails with a 409 that reads like a permission problem. PermissionDenied is now separate from AuthFailed. Folding 403 into 401 sent a user to re-check a credential that was working perfectly, with reads succeeding and only the write refused (observed against a real server). The usual cause is an app password created without "Allow filesystem access" — which signing in again will not fix. Assisted-by: LLM |

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 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 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. |
