Refuse a scan whose root has gone, instead of reporting it empty
FR-PLAT-AND-2, and a silent failure on both platforms. `dr_sync::scan` stepped over a NotFound or PermissionDenied the way it does for a child that vanished mid-walk -- correct for a child, wrong for the root, where it ended the walk, returned Ok with nothing in it, and reported a successful scan of a library that was no longer there. A lost root is now its own error. The images under it are marked Availability::Offline per FR-CAT-9 and no catalog row is deleted; `library::persist` clears the mark per file as each one is listed again, so a root that comes back needs no repair step. Partly satisfied rather than closed, and the gap is worth stating. The recovery half is real and reachable on Android today, because `map_status` turns Nextcloud's 403 and 404 into it and Nextcloud is how a phone actually gets a library in this build. The causes the requirement names -- revocation, reinstall, a removed card -- are properties of a persisted tree permission, and there is none: SAF does not exist here, `SourceRef::Document` is constructed only in test modules, and `LocalStorage` rejects the variant outright. When SAF lands it becomes a third producer of this error and nothing above it changes, which is why the discovery belongs in the connector.

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. |

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.

Diagnose the refused sidecar: the library mount is create-only
Ratings and edits made on the tablet queue and are then refused on reconnect,
on a credential that pushes the catalog to the same library root in the same
sync pass. Chased on the device, since that is where the account lives.
A failed PUT now logs the server's own words, and on a 403 asks the parent
what rights it reports. The answer:
PUT .../PhotosRaw/2026/2026-08-03/_MG_9221.drsc -> 403
<s:exception>Sabre\DAV\Exception\Forbidden</s:exception>
parent permissions: MGNVCK
`M` mounted, `G` readable, `N` renameable, `V` moveable, `CK` create files and
folders. Absent: `W`, update an existing file, and `D`, delete. So `PhotosRaw`
is a mounted share that accepts a file once and refuses every change to it
afterwards.
That is the whole bug, and it is not one this side can retry its way out of. A
sidecar is rewritten on every rating and every edit, so the first judgement on
a photograph is written and every later one is refused — which reads as sync
being broken rather than as a share missing one permission. **The fix is to
grant update, and ideally delete, on that mount.**
`PermissionDenied` now says so, rather than "not allowed to write here", which
sent the reader to re-check a login that was working. Its test asserts the
intent — points at the folder, never at the credential — rather than a
phrase, so saying it better cannot read as a regression.
Also adds a `put_probe` example that makes the same request from a stored
session, for diagnosing this from a desktop when one is signed in.

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 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. |
