📝 WalkthroughWalkthroughThe desktop artifact build now performs platform-specific prerequisite checks for Linux, macOS, and Windows. It reports structured errors with installation guidance. Documentation and tests cover the new checks. ChangesDesktop build preflight
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk:🟡 Moderate · up to Desktop artifact builds can still pass the new prerequisite checks when the required Rust target is unavailable, causing Linux and other affected builds to fail later during compilation instead of producing an actionable early error. This concrete correctness gap should be fixed before merge. Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)
Full details: Description checkExplanation The description explains what changed, why it changed, the affected platforms, verification steps, and the absence of UI changes. It does not use the template headings or include the checklist, but it is otherwise sufficiently complete and relevant.

scripts/build-desktop-artifact.ts at lines 1702-1704 and 1749-1751 with a
command that verifies the Rust standard library for each target is actually
installed, rather than merely recognized by rustc. Update the ChildProcess.make
calls while preserving their existing target-specific validation and error-label
behavior.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — The PR adds substantial cross-platform preflight logic that can stop existing desktop artifact builds before web, native, and packaging work begins. Documentation and tests are isolated, but the automatic build gating and expanded toolchain checks materially change the existing build workflow. You can add or adjust custom eligibility rules.

… component Upstream pingdotgg#8975 asks vswhere for Microsoft.VisualStudio.Component.VC.Tools.x86.x64.Spectre (and the ARM64 twin), which the Visual Studio 2022 catalog does not contain — the installer reports "Cannot find package ... in product graph" — so the msvc probe failed on every Windows host and the 0.0.50 Blade build aborted. The Spectre-mitigated libraries ship as VC.Runtimes.<arch>.Spectre; probe that id instead. Guard script now requires the fix so a future merge cannot restore the unsatisfiable id.
Desktop artifact builds currently fail late when a host is missing Rust or native platform tooling, leaving contributors to infer system packages from compiler output. Contributor setup documentation does not describe the full platform requirements.
This adds early capability-based preflights for Linux, macOS, and Windows, with actionable platform guidance and focused coverage. It documents the required Rust targets, native compiler tools, Linux X11 headers, Visual Studio components, and signing boundaries.
Verification:
vp test run scripts/build-desktop-artifact.test.tsvp lint scripts/build-desktop-artifact.ts scripts/build-desktop-artifact.test.tsvp exec tsc -p scripts/tsconfig.json --noEmitvp fmt --checkBuilt with GPT-5 via Codex.
Note
Low Risk
Changes affect local/CI desktop packaging ergonomics and docs; behavior is additive early validation with tests, not production runtime paths.
Overview
Desktop artifact builds now fail fast with structured errors when the host is missing required tooling, instead of dying mid-build with opaque compiler output.
buildDesktopArtifactruns newpreflightLinuxDesktopBuild,preflightMacDesktopBuild, andpreflightWindowsDesktopBuildprobes when building on the matching host (Rust/Cargo and installed targets, Linux cc/make/ImageMagick, macOS Xcode tools including universallipo, Windows Python 3, MSVC/SDK viavswhere, andtar.exewhen WSL runtime bundling is enabled). Missing pieces surface as tagged errors that list gaps and point atrustup target add, apt install lines, or the expanded docs.resolvePythonForNodeGypnow verifies candidates actually run as Python 3, so PATH shims to Python 2 no longer pass preflight.T3CODE_DESKTOP_REUSE_RESOURCE_MONITORstill skips Rust checks when reusing a cached monitor binary.CONTRIBUTING.md links to the maintainer scripts guide;
