The phone client is Tauri v2 mobile (operator decision), so it reuses the Vue frontend and the Rust store and sync engine that already exist rather than becoming a third implementation to keep in step by hand. gen/android is committed. tauri android init generated it, its own .gitignore already excludes the build outputs and every keystore file, and CI must not have to regenerate a project that manifest edits will accumulate in. What the scaffold confirms is that the image's JDK pin was load-bearing rather than incidental: Tauri templated Gradle 8.14.3 with AGP 8.11.0, and CI-android's versions.env records that JDK 25 needs Gradle 9.1.0+ and that anything older fails with an opaque "25.0.3" message. Picking 17 for ci-tauri-android avoided exactly that. namespace and applicationId came out as com.fabledsword.thoughtsync, matching the desktop identifier, so the app-data story stays consistent. The lane builds a DEBUG APK for arm64 only. Release APKs need signing, and the keystore has to be generated by the operator and never pass through CI logs or an agent session — the constraint recorded for the updater key applies unchanged. Gradle's throwaway debug keystore needs nothing from anyone, so this can prove the app compiles and packages today and grow a signed job when a key exists. arm64 is every real device; the image carries the other three ABIs, so widening is a word. Triggered by frontend/** as well as desktop/**, because generate_context! compiles the frontend into the app — the same reasoning that widened desktop.yml. Android, desktop and web are peers on one quality bar, and a frontend commit that skipped this lane would ship a stale phone build. Green here will mean it BUILT. A Linux runner cannot execute an APK, so nothing in this lane proves the app runs, renders, or is usable by finger. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
ThoughtSync desktop (Tauri v2)
Local-first desktop client. The window loads the shared Vue 3 frontend from
../frontend; the Rust core (src-tauri) owns the on-device store and the opt-in
sync engine (built out across the M10 milestone). Works fully offline; optionally
syncs to a self-hosted ThoughtSync server.
Layout

Cargo.toml

The Vue frontend is the sibling ../frontend package, shared with the web
build. On desktop it is backed by a local data source via
frontend/src/adapters/ (M10.3) instead of the server REST API. frontend and
src-tauri are siblings, not nested, so the beforeDev/beforeBuild
commands cd "$(git rev-parse --show-toplevel)/frontend" to resolve regardless of
the CLI's working directory.
Prerequisites
The toolchain (Rust + Node + WebKitGTK 4.1 + tauri-cli) is provided by the
ci-tauri CI image. For local dev: install Rust + Node, cargo install tauri-cli,
and the Tauri v2 Linux system deps — see CI-tauri/Dockerfile in the CI-runner
repo for the exact apt list (libwebkit2gtk-4.1-dev, libgtk-3-dev, librsvg2-dev,
libayatana-appindicator3-dev, libxdo-dev, patchelf, ...).
Dev
cd desktop/src-tauri && cargo tauri dev
beforeDevCommand starts the Vite dev server (port 5173) in ../frontend.
Build (Linux)
cargo tauri icon "$(git rev-parse --show-toplevel)/frontend/public/icon.svg"
cd desktop/src-tauri && cargo tauri build # -> .deb + .AppImage
App icons are generated from the frontend's icon.svg via cargo tauri icon
(not committed; CI does this before cargo tauri build). Bundle targets: deb,
appimage (Linux-first; Windows/macOS later, no code changes expected).
Status
Scaffold (M10.2): boots the shared Vue UI in a native window. Until the local data
adapter lands (M10.3 + M10.5) the app has no server configured, so it shows the
login screen without a working backend — full offline functionality arrives with
the local SQLite store (M10.4) + adapters/local.ts (M10.5).
