Step 4 of M314. `desktop/packaging/build-version.sh` was one generator feeding the desktop bundles AND the Android APK off `GITHUB_RUN_NUMBER`, so a Kotlin-only commit re-versioned the desktop and a Rust-only commit re-versioned the phone. Note 3127 §3 cites this repo as its example of that failure. It is replaced by `packaging/version.sh` — one definition of HOW to derive, three file sets, and the sets in one place. Lives at the repo root rather than under desktop/, because it serves three artifacts now and a shared thing filed under one consumer ends up owned by it. ## Two values, and the clock chosen per value (§2) desktop key 1.0.<minutes since 2020-01-01> commit time desktop display 2026.08.28.0900 commit time (#3181 shows it) android versionName commit time android versionCode <minutes since 2020> BUILD time server version 2026.08.28.0900 commit time, no ordering key Every human-readable version in the repo is now one shape. The two exceptions are not version names at all — they are bare monotonic integers a comparator reads and nobody quotes. The desktop needs a separate key because Tauri parses `latest.json` with the semver crate and `2026.08.28.0900` fails it twice (four segments, and `08` is a leading zero). `1.0.` and not `0.0.`: the minor has to clear the installed `0.2.466` line or every dev user is stranded on "up to date" permanently. Android's code comes from BUILD time while the desktop's key comes from COMMIT time, deliberately. Android hard-fails a downgrade with INSTALL_FAILED_VERSION_DOWNGRADE and leaves a channel you cannot get out of, so its key must be monotonic by construction; the desktop merely declines to offer an update, which a guard can catch. ## The bug this found in itself The shallow-clone guard `exit 1`-ed inside a function called as `$(...)` — which ends the SUBSHELL, not the script. `display` still failed, but only because `date` then choked on the empty string. `key` printed the error to stderr, emitted `1.0.-26297280`, and exited ZERO. That is precisely the failure the guard exists to prevent: a too-low version on a green lane, and too-low is the direction you cannot recover from. It resolves into a global in the parent shell now. The test is parametrized over both requests, because one path was covered and the other was broken in exactly the way the covered one was meant to rule out. ## Also `fetch-depth: 0` on every job that derives — four of them, and only ci.yml's gate had it. Depth-1 is silently wrong rather than loudly broken (§6.1). The file sets include each artifact's BUILD RECIPE (its workflow, and `packaging/`). A workflow file is not shipped, but change a Gradle flag and the bytes change while the source does not — and once step 6 skips a build whose version already exists, that serves the OLD artifact on a green run. The base images are deliberately NOT resolved at derive time: that is an external lookup, which §7's corollary forbids. `Dockerfile` is already in the server's set, so pinning `FROM` by digest in step 6 puts the base inside the set for free. `build-version.sh` is deleted, its last consumer (the pacman packager) moved over, and the one finding worth keeping out of its header — why not a `-dev.N` prerelease — is preserved in the successor. #3144 Co-Authored-By: Claude Opus 5 <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
desktop/
src-tauri/
Cargo.toml

main.rs # thin shim -> lib::run()
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).
