Additional notes for reviewers

Mobile Canvas combines a JavaScript canvas extension with an MCP server backed by a Native AOT .NET executable. The repository includes gzip-compressed, platform-specific executables under runtimes/ because Copilot plugin installs copy files without running a package restore or build. On first use, the shared resolver verifies every extracted file against SHA-256 values in runtimes/manifest.json and writes it to a content-addressed per-user cache.

The host binds only to 127.0.0.1, canvas sessions exchange a single-use bootstrap secret for an authenticated session cookie, and device data is not uploaded. The build, packaging, checksum, code-signing, and permission model is documented at https://github.com/Redth/mobile-canvas-ghcp/blob/c930769d41f07852baeeb407ded76d5ba83c06d2/docs/distribution.md.

iOS support requires macOS, Xcode Simulator runtimes, idb_companion, and user-granted Screen Recording/Accessibility permissions. Android support requires the Android SDK. Windows and Linux use screenshot polling where the macOS-only hardware video helper is unavailable.

The candidate commit passed the repository CI and Awesome Copilot's external-plugin quality gates, including Vally lint, canvas structure validation, version matching, and an isolated Copilot plugin install smoke test.
