The client half of task 1942's server work. Metadata already rides the delta feed; this fetches the payload so a synced image exists on the device. Blobs are filed under their own sha256, so the same image attached to five notes is stored once and re-downloading it is free — the dedupe the task asks for falls out of content addressing rather than needing bookkeeping. The hash is also the integrity check, applied on the way IN. Bytes that don't hash to what the server advertised are refused rather than filed under a name that lies about them — and because the blob then still counts as missing, the next sync simply tries again. SECURITY: the hash arrives in a server response and becomes a FILENAME, so it is validated as 64 hex characters before touching the filesystem. Without that, a hostile or buggy server could send "../../..." and steer a write outside the blob directory. Tested. A failed attachment never fails the sync. Notes are the primary data and have already landed; aborting here would let one unreachable file block every future sync. Counted, logged, surfaced in the UI as "they'll retry on the next sync", and retried because the blob is still absent. sha2 is pure Rust, so the Windows cross-compile lane pays nothing for it — the constraint recorded in ci-requirements.md. SPLIT, deliberately: this stores the bytes but does NOT yet render them in the webview. That half needs a custom URI scheme or the asset protocol, whose URL form differs by platform (Windows uses http://scheme.localhost/, others scheme://localhost/) — and CI cannot verify webview rendering at all, being headless with no webview. Guessing at it here would ship an unverifiable change on the most fragile lane. Follow-up filed; synced images will show as broken until it lands.

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.

lib.rs # tauri::Builder entry point
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).
