Wires the workspace through `cargo apk build`. After this commit
`cargo apk build -p solitaire_app --target x86_64-linux-android`
produces a debug-signed APK at `target/debug/apk/solitaire-quest.apk`
containing all assets and `lib/x86_64/libsolitaire_app.so` — runnable
on the AVD or a physical x86_64 device.
The five gating points discovered by iterating compile cycles:
1. solitaire_app split into bin + lib. cargo-apk needs a `cdylib`
to bundle as `libmain.so`; pure-bin crates panic with
"Bin is not compatible with Cdylib". `src/lib.rs` carries the
ECS bootstrap as `pub fn run`; `src/main.rs` is a 3-line shim
that delegates for the desktop `cargo run` path.
2. `[package.metadata.android]` pins target SDK 34 / min SDK 26
so cargo-apk doesn't probe for whatever default it ships
(which on this machine was an uninstalled API 30). `assets =
"../assets"` lets the same asset directory feed both desktop
and APK.
3. Workspace `bevy` features add `android-native-activity` (the
Bevy-side glue that pairs with cargo-apk's NativeActivity
wrapper). The feature is target-gated inside bevy_internal so
desktop builds compile it out.
4. `arboard` (clipboard, used by Stats's "Copy share link") has
no Android backend — `cargo apk build` fails with E0433 on
`platform::Clipboard` if unconditional. Target-gated to
`cfg(not(target_os = "android"))`; the system surfaces an
informational toast on Android until JNI ClipboardManager is
wired in the Phase-Android round.
5. `keyring` + `keyring-core` cannot compile for android — the
transitive `rpassword` uses `libc::__errno_location` which
bionic doesn't expose. Both crates target-gated; `auth_tokens`
ships a stub on Android that returns `KeychainUnavailable` for
every call, matching how callers already handle a Linux box
without Secret Service.
Cosmetic post-pass panic: cargo-apk panics AFTER the APK is signed
when it tries to also wrap the bin target. The APK on disk is
unaffected. Working around this with `cargo apk build --lib` is
the next small step.
What's verified:
- Desktop `cargo build`, `cargo clippy --workspace --all-targets`,
and `cargo test --workspace` all clean.
- `cargo apk build -p solitaire_app --target x86_64-linux-android`
produces 54 MB debug APK with libsolitaire_app.so + assets.
What's NOT yet verified:
- Whether the APK actually launches on the AVD / a phone (next
step: `adb install` + `adb logcat` against the bevy_test AVD).
- Whether `dirs::data_dir()` on Android returns a usable path
(sync / persistence will surface this if not).

Art pass (Phase 4):
- Generate placeholder PNG assets: face.png, back_0–4.png, bg_0–4.png via
solitaire_assetgen gen_art binary (16×16 RGBA, embedded via include_bytes!)
- Add FiraMono-Medium font (assets/fonts/main.ttf) embedded at compile time
- Add FontPlugin: loads font at startup, exposes FontResource; gracefully
falls back to default handle when Assets<Font> absent (MinimalPlugins tests)
- Wire CardImageSet into card_plugin: face/back PNGs replace solid-colour
sprites when available; tests continue using colour fallback via MinimalPlugins
- Wire BackgroundImageSet into table_plugin: bg PNGs replace solid-colour
background; empty set inserted when Assets<Image> absent in tests
- Fix hint highlight system (input_plugin): tint sprite.color directly instead
of replacing the whole Sprite (which would discard the image handle)
- Export FontPlugin, FontResource, CardImageSet from solitaire_engine::lib
- Register FontPlugin in solitaire_app before other plugins
Dependency upgrades (latest releases):
- keyring "2" → keyring "4" + keyring-core "1" (v4 split architecture into
separate core library crate)
- auth_tokens.rs: Entry::new now returns Result; delete_password →
delete_credential; NoDefaultStore error variant handled
- solitaire_app: add keyring::use_native_store(true) at startup for Linux
Secret Service / macOS Keychain / Windows Credential Store selection
ARCHITECTURE.md: fix Edition 2025→2021, update asset pipeline section,
add FontPlugin/CardImageSet/BackgroundImageSet to plugin and resource tables,
update Section 14 to reflect actual include_bytes!() rendering approach,
add Decision Log entries for embedded PNG and font decisions

- pkg/solitaire-quest/PKGBUILD: builds solitaire_app binary, depends on
alsa-lib, libxkbcommon, systemd-libs (Bevy Linux requirements); check()
runs only non-Bevy crates (solitaire_core, solitaire_sync) since Bevy
integration tests require a GPU/display unavailable in chroot
- pkg/solitaire-quest-server/PKGBUILD: builds solitaire_server binary,
installs systemd service unit and hardened environment file template
- pkg/solitaire-quest-server/solitaire-quest-server.service: systemd unit
with ProtectSystem=strict, NoNewPrivileges, dedicated service user
- pkg/solitaire-quest-server/server.env: documented env template installed
to /etc/solitaire-quest-server/server.env (mode 0640, listed in backup=)
- LICENSE: add MIT license
- Cargo.toml: add license = "MIT" to [workspace.package]
- All member crates: add license.workspace = true
Both PKGBUILDs follow the Arch Rust package guidelines:
prepare() uses --locked + cargo fetch
build() uses --frozen --release -p <crate>
RUSTUP_TOOLCHAIN=stable and CARGO_TARGET_DIR=target set in each stage

- solitaire_server: Axum auth, sync push/pull, leaderboard, daily
challenge, account deletion, JWT middleware, rate limiting via
tower_governor, SQLite migrations, health endpoint
- solitaire_server: expose build_test_router (no rate limiting) so
integration tests work without a peer IP in oneshot requests
- solitaire_sync: SyncPayload, merge logic, shared API types
- solitaire_data: SyncProvider trait, LocalOnlyProvider,
SolitaireServerClient, auth_tokens keyring integration, blanket
Box<dyn SyncProvider> impl
- solitaire_data/settings: derive Default on SyncBackend (clippy fix)
- .sqlx/: offline query cache so server compiles without a live DB
- sqlx: removed non-existent "offline" feature flag
- keyring v2: fixed Entry::new() returning Result<Entry>
- sqlx 0.8: all SQLite TEXT columns wrapped in Option<T>
- Integration tests: max_connections(1) on in-memory pool so all
connections share the same schema
All 191 tests pass; cargo clippy -D warnings clean.
