Summary

• stop embedding the legacy runtime.erofs image in ArcBox.app and release artifacts
• preserve architecture-specific runtime manifest entries when staging local boot assets for Development builds
• force full DMG builds to embed Rust binaries even when Local.xcconfig enables SKIP_RUST_BUILD
• fail release validation if runtime.erofs is reintroduced

Validation

• devenv shell -- make lint-xtask test-xtask
• 9 xtask tests passed
• git diff --check

Dependencies

• Remove the runtime EROFS image boot-assets#48 publishes arcbox-boot 0.8.0 and a rootfs without the legacy runtime mount
• Materialize guest runtime on Btrfs arcbox#529 materializes verified runtime assets onto the guest Btrfs data disk and removes direct VirtioFS execution
• after the ArcBox release is published, update arcbox.version before releasing Desktop

[greptile-apps]

Greptile Summary

The PR updates macOS packaging to omit the legacy runtime.erofs, preserve architecture-specific runtime metadata for local Development assets, and validate versioned runtime binaries in release artifacts.

• Stages local boot assets after prefetching their runtime manifest entries.
• Selects profile-appropriate boot caches and removes stale embedded assets.
• Forces the intended Xcode Rust-embedding behavior for each DMG build mode.
• Rejects release bundles that contain the legacy runtime image.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.

Important Files Changed

Filename	Overview
xtask/src/commands/macos/dmg.rs	Updates resource preparation, cache selection, embedding, and bundle verification for versioned guest runtime materialization.
xtask/src/commands/macos/dmg/tests.rs	Adds coverage for local manifest preservation, profile-restricted cache reuse, stale asset replacement, and host-target validation.
.github/workflows/release.yml	Extends release validation to reject legacy runtime images and verify binaries beneath the manifest asset-version directory.
