dtourolle caae65c78d Import from an SD card or card reader on Android
Import was switched off on Android: `imports_supported` was true only for
`target_os = "linux"`, and its comment said Android has no path to read a
card by and nowhere to write the copies. Neither holds. With "all files
access" (MANAGE_EXTERNAL_STORAGE, API 30) an app reads the root of an SD
card or a USB card reader by path, `/storage/9C33-6BBD`, and the importer
only ever writes into its own staging directory, which is a plain
directory on Android too. So the engine runs unchanged; what was missing
was finding the card and the permission.

- The manifest declares MANAGE_EXTERNAL_STORAGE, and
  READ_EXTERNAL_STORAGE up to API 29 with requestLegacyExternalStorage,
  which is the same access on 28 and 29.
- Cards.java lists the mounted non-primary volumes through
  StorageManager and opens the system "All files access" page for this
  app. dr_ui::cards is the JNI bridge, through saf's helpers.
- The import page on Android asks for the permission with an "Allow
  access" button until it has it, rather than showing an empty list that
  reads as "no card", and watches for the grant so the list fills in when
  the user comes back from settings.

Google Play restricts this permission to file managers and the like;
DarkRoom is sideloaded, so that does not apply.

dtourolle 92d4b23bed Give an album a folder on the tablet, through Android's folder picker
Android's only export destination was the library on the server
(ExportTarget::available), because writing to the device goes through
the Storage Access Framework and nothing did. An album's folder on the
tablet is now chosen in the system's tree picker — which has its own
"Create new folder" — and exports are written into it with
DocumentsContract.

The picker answers through onActivityResult, and the main activity is
NativeActivity, whose result is not ours. FolderPicker is a translucent
activity that only asks: it starts ACTION_OPEN_DOCUMENT_TREE, takes a
persistable grant (a folder is chosen once and exported to for months),
leaves the URI in a static, and finishes. Rust polls it from a Slint
timer — one static call, rather than a registered native method and a
thread to deliver on.

Two things the first build on the tablet got wrong, recorded where they
are fixed:

- Our classes must be loaded through Context.getClassLoader(). The
  class of what ndk_context holds is a framework class from the boot
  loader, which reports every class in the APK as not found.
- What ndk_context holds is the application context, not the activity,
  and starting an activity from it throws without FLAG_ACTIVITY_NEW_TASK.

Saf.write creates the document (or, under Overwrite, reopens the one of
that name with "wt" so a shorter file does not keep the old tail) and
returns the name the provider actually gave it, since SAF renames on a
collision by itself; the album records that name. A tree URI reads in
the sidebar as its folder ("Pictures/Web"), not as a content:// string.

dtourolle 352e59498b Open the bundled manual from Help and from Settings
The packages now carry the manual, but nothing in the application opened
it: the help sheet listed gestures and stopped there.

The help sheet gains a Manual button beside Done, and Settings a Manual
row under About beside the version. Both go through dr_ui::manual, which
finds the installed page through dr_plat::system_data_dirs (the package's
share directory on Linux, the executable's directory on Windows), and a
development build also in the checkout it was compiled from. A copy with
no manual says so on the status line rather than doing nothing.

On the desktop the page goes to the system browser. A section is a URL
fragment, and xdg-open's generic mode and Windows' FileProtocolHandler
both turn a file: URL into a path and drop the fragment, so a section is
opened through a one-line redirect page written to the data directory:
the opener gets a plain path, which every opener keeps, and the browser
follows the redirect to index.html#section itself. The launcher behind
the sign-in's open_in_browser is split out so both share it; the https
check stays with the sign-in.

Android has no path to give a browser: an asset is not a file, a copy in
private storage is unreadable to other apps, a file: URI across apps is
refused, and a content: URI leaves the browser resolving every picture
against the provider. So ManualActivity, a WebView reading
file:///android_asset/manual/index.html straight out of the APK, shows
it, started by class name with the section as an extra. JavaScript is
off, links off the page go to the browser, and the theme is day-night so
the page's own light and dark follow the system. A test checks that the
manifest, the Java class and dr_ui agree on the name and the extra.

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 2d95807542 Package the models on every platform, not just the phone
The Android bundling landed the weights under that platform's asset directory,
which was the wrong home the moment a second packager wanted them. `makepkg -si`
produced a desktop install with no model at all — the same "no face model is
installed" the phone used to show, for the same reason: nothing put the files
anywhere the app looks.

So `models/face/` at the root is the one copy, and both packagers read it:
assemble-apk.sh bundles it as APK assets, and the PKGBUILD installs it to
/usr/share/darkroom/models. Both refuse an LFS pointer rather than shipping a
130-byte file that fails inside the graph loader on a user's machine.

`face_models` now searches three places, most specific first: the account's own
directory, the shared user directory, then $XDG_DATA_DIRS. So a packaged pair is
found automatically and a pair the user placed by hand still outranks it — which
is what keeps a deliberate choice of weights from being overridden by an
upgrade.

$XDG_DATA_DIRS rather than a hard-coded /usr/share: that is the variable a
distribution, a prefix install or a Nix-style store already sets to say where
its data went, and its documented default is exactly the two paths that would
otherwise have been hard-coded. Empty on Android, which has no such directories
— there the APK's copy is unpacked into the shared user directory instead,
because an asset inside a package is not a path anything can read from.

Verified: the APK still carries both models at assets/models/, the PKGBUILD
parses and installs from the new path, 467 tests pass.

Includes the pkgver 0.6.0 → 0.7.0 bump that was already sitting uncommitted in
the working tree.

dtourolleandClaude Opus 5 eaafacc3fb Give the phone the model it had no way to obtain
Face indexing was compiled into the APK all along — dr-ui takes dr-face with
`inference` on every target, so SCRFD, alignment, MBF, calibration and
clustering were all in there. What was missing was the weights, and on Android
there was no way to supply them.

Route C (docs/faces.md §2.2) says the user obtains the model and the app loads
it. On a desktop that is a real gesture: drop two files in
~/.local/share/darkroom/models/ and indexing starts working. On Android it is
not a gesture at all. `internal_data_path` is app-private, `run-as` needs a
debuggable build, and the in-app fetch route C specifies was never built — so
the settings page reported "no face model is installed" on every launch with
nothing behind the message. Not "off until you supply weights"; off.

So the shape-fixed pair goes into LFS under the APK's assets, assemble-apk.sh
copies it into the package, and `android_main` unpacks it to the shared models
directory before anything asks whether a model is present.

Three things that are not incidental:

The models directory is now shared across accounts rather than per-account.
Weights are identified by `faces.model_id`, not by who is signed in, so two
accounts had no reason to hold two copies — and the unpack runs before any
session exists to key a per-account path off. `face_models` still prefers a
per-account directory when one is populated, so anyone mid-migration keeps the
ability to pin one library to its own pair.

The unpack writes under a temporary name and renames. `face_models` decides
availability on `is_file()` alone, so a copy truncated by the process being
killed would leave a file that passes that test and fails inside tract —
reported to the user as a broken model rather than a missing one.

assemble-apk.sh refuses an LFS pointer. At ~130 bytes it looks exactly like a
model to `cp`, and unchecked it reaches the device and fails in the graph
loader instead of telling someone to run `git lfs pull` — the same guard
dr-segment's build script applies to yolo26n-seg.onnx.

The licensing half is unchanged and recorded in §2.2a: the InsightFace grant is
research-only, this is a private repository and a self-installed build, and
these files come back out before anything is published. The weights are still
not a cargo build input — dr-face has no `models/` directory and no
`embedded-model` feature, and nothing in the build reads them. The APK assembly
step copies two files and is the only thing in the tree that knows they exist.

Verified on device: both models unpack on first launch (2524817 and 13616095
bytes) and the APK carries them at assets/models/.

dtourolleandClaude Opus 5 3cfa78cde2 Give the app a face and a name on the launcher
There was no icon anywhere, and on Android that was not a missing line in the
manifest. `aapt2 link` was being handed a manifest and nothing else, so the
APK carried no res/ and no resources.arsc — there was no table for an
`@mipmap/...` reference to resolve against even if one had been written.
Packaging now compiles the resource tree first and links the result in, which
is the two steps aapt2 insists on: link reads compiled input only, never a
directory.

That absent table is also why the launcher caption was blank, which had
looked like a second, separate bug. `android:label="DarkRoom"` was there and
correct the whole time, and Settings' App info read it fine; the launcher
could not, because resolving a label goes through the package's Resources and
there were none to open. Nothing about the label changed here. It came back
with the table under it.

`android:icon` then names one drawable for both icon generations, because the
`anydpi-v26` qualifier is what separates them. API 26 and up take the adaptive
icon and its three layers; the third of those, monochrome, is what lets
Android 13 recolour it rather than drop the app out of the themed set. Below
26 the same name lands on a density-matched PNG. `roundIcon` is deliberately
absent — a launcher old enough to read it is one that would ignore the
adaptive XML, and minSdk is 28.

The desktop icon is one `@image-url` on the window, and the only raster asset
in a UI that is otherwise entirely Path. The reasoning at the top of
icons.slint does not reach it: that is about glyphs a font might not carry,
and this image is never drawn by us at all. It goes to the window manager,
which wants pixels and composites them unmasked, so it is pre-shaped with
rounded corners rather than square the way the Android layers are.

Which exposed Slint's resource default. An `@image-url` compiles down to the
absolute path it had on the build machine, to be opened at runtime — already
wrong for Android, where the build happens under /work inside a container and
no such directory exists on the device, and wrong silently, as an image that
loads empty. `EmbedFiles` puts the bytes in the binary instead. It reaches
nothing else, since every glyph is a Path.

Verified on a device: the APK installs and the home screen draws both the
icon and "DarkRoom" under it, where before it had neither. In the link step
the adaptive icon resolves at all six densities and resources.arsc lands
uncompressed, which API 30 requires and the existing zipalign preserves. On
the desktop by reading _NET_WM_ICON off the running window — 256x256, as
handed over. Where that actually shows is narrower than it sounds, and the
comment says so: Wayland ignores the property in favour of matching app_id
against an installed .desktop file, which this repo does not install.

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.

dtourolle 9a24623e35 Fix the workspace build off-device
Two breaks that only appeared on a full `cargo test --workspace`.

`slint::android` exists only when compiling for Android, so darkroom-android
failed to compile on the host even though it is a workspace member. The entry
point is now gated on the target rather than on a feature.

The timeline forwarded `scrub` where the Timeline component declares
`scrub-to`, which the Slint compiler rejects.
