The #295 unit suite now runs in CI, but the Windows clean runner exits before the lib test harness starts with STATUS_ENTRYPOINT_NOT_FOUND when optional native runtime entrypoints are absent. Windows still needs cfg/link coverage, while macOS and Linux can execute the shared Rust unit suite.
Constraint: Preserve the new Rust test gate without making optional Windows native runtime installation a CI prerequisite.
Rejected: Install Foundry/Windows App Runtime into every CI run | broader, slower, and unrelated to backend unit-test coverage.
Confidence: high
Scope-risk: narrow
Directive: Do not switch Windows back to executing the lib test binary until the optional native runtime dependency is present on the runner.
Tested: cargo test --manifest-path openless-all/app/src-tauri/Cargo.toml --lib
Not-tested: Windows CI rerun before push.
