First Android build failed at openssl-sys: "Could not find directory of OpenSSL installation". reqwest is pinned to native-tls, which is right for Windows — it resolves to schannel there and keeps C and assembly out of the cross-compile — but on Android it resolves to OpenSSL, and there is no Android OpenSSL in the image to link against. Vendored rather than rustls. rustls builds faster and was the obvious fix, but it ships its own root store, so the phone would trust a different set of certificates than the desktop: a self-hosted server behind a private or enterprise CA would work on one surface and fail on another. Peer surfaces that quietly disagree about who to trust is a worse outcome than a slower build, so one TLS stack stays everywhere and OpenSSL gets compiled from source with the NDK toolchain — which is what perl and make are in ci-tauri-android for. Scoped to cfg(target_os = "android") so nothing changes for the Linux, Windows or web lanes; declared as a direct dependency purely to flip the feature, since cargo's unification then applies it to the copy native-tls pulls in. Cargo.lock regenerated in the same commit, per the documented procedure — the --locked gates in every lane fail otherwise. openssl-src 300.6.1+3.6.3 joins.

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.

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).
