js-dos MCP
ZIP validation uses zip 9.0.5 with explicit local/central header consistency checks for GHSA-m665-v7pm-7grj.
Published emulators 8.5.3 is integrated. Native Linux x86_64, Windows x86_64 and macOS Intel/arm64 acceptance passed, including native audio cleanup, all five presets without a local SDK patch and extracted-archive smoke tests. Connection through OpenCode 2.2.5 is verified on Linux; that version has a cold-start readiness race described in the README.
CI run 43047052131, PR head 0372f4487d6d1b1cc181c8eff29b85b41f91cad4, produced these measured draft artifacts. Exact binary/archive SHA-256 values, browser versions and OS releases are recorded in acceptance/43047052131.json. The archives record the tested PR merge commit 0a311e56644b8dbc095fba3587cad2e45f49d811 and a clean working tree. Later documentation changes do not change these historical measurements.

The release contains a local stdio MCP executable with embedded Studio, DOSBox and DOSBox-X workers, libzip and standalone HTML, Vite, React, Vue and Angular templates.
Each archive includes release.json with the binary size, SHA-256 and source commit. A separate .sha256 file covers the archive. Runtime asset sizes and hashes are in asset-manifest.json. License notices and immutable upstream source revisions are included beside the executable.
Use the system requirements, OpenCode V2 configuration and permissions described in the included README. No Node.js or Rust toolchain is needed to start the executable. Framework development requires its own explicitly installed Node.js dependencies. Unsigned binaries may need operating system approval.
External sockdrive/qcow2 disks are not included in snapshots or generated projects. Browser autoplay and background throttling policies still apply. CI readiness and browser observations do not prove that an arbitrary game works correctly.
VERIFICATION.md distinguishes native CI results from local checks and records the remaining browser and external-resource limitations.
Published release verification
All four native targets passed release CI 43192639863 at commit 2ea409b41189c380df5a91640bdbec8cf1e100e3. Downloaded public archives were checked against their SHA-256 files and matching browser reports. Each contains zip 9.0.5, emulators 8.5.3 and js-dos 8.5.4 assets. The extracted Linux executable also passed stdio checks with an empty child PATH.
The published verification record records current artifact checksums and executable sizes. The earlier CI measurements above are historical, not these release artifacts.
