Error message

Fresh production sidecar/helper build did not produce the expected artifacts

What it means

After buildArtifacts() runs `pnpm exec electron-vite build` and `pnpm build:computer-macos`, the script checks that out/main/computer-sidecar.js and the helper .app/Contents/MacOS/orca-computer-use-macos exist. If either is missing, the build failed silently or produced output at a different path.

Solutions

1. Run `pnpm exec electron-vite build` and `pnpm build:computer-macos` manually and verify the output paths
2. Confirm sidecarPath (out/main/computer-sidecar.js) and helperPath constants match actual build output
3. Check the native build for silent failures: missing Xcode, code signing errors, or skipped targets
4. Ensure the Swift helper build target name and .app bundle name match Orca Computer Use.app

Example fix

// before: build config changed the output dir to out/dist
// sidecarPath = path.join(repoRoot, 'out', 'main', 'computer-sidecar.js') // stale

// after: align constant with actual build output
const sidecarPath = path.join(repoRoot, 'out', 'dist', 'main', 'computer-sidecar.js')

// Verify build artifacts exist before running the benchmark
const sidecarPath = path.join(repoRoot, 'out', 'main', 'computer-sidecar.js')
const helperPath = path.join(repoRoot, 'native', 'computer-use-macos', '.build', 'release', 'Orca Computer Use.app', 'Contents', 'MacOS', 'orca-computer-use-macos')
if (!existsSync(sidecarPath) || !existsSync(helperPath)) {
  throw new Error('Build artifacts missing — run pnpm exec electron-vite build && pnpm build:computer-macos first')
}

When it happens

Trigger: existsSync(sidecarPath) or existsSync(helperPath) returns false at line 539, meaning the build completed without error but did not produce the expected files at the hardcoded paths.

Common situations: Build config change moved the output directory; native build (Swift/Xcode) skipped due to missing toolchain; the helper .app bundle structure changed; electron-vite output dir was customized; build exited 0 but a sub-step was skipped.
