Node engines

When Node.js is one of the selected targets and the scan root contains package.json, Runtime Checker compares the detected minimum with engines.node.

{
	"engines": {
		"node": ">=22"
	}
}

A warning appears when the field is missing, invalid, or does not allow the detected minimum. A declared lower bound that is stricter than the scan result is informational because the package may require that newer version for reasons the static scanner cannot see.

runtime-checker .dist --runtime node --fix

--fix creates or replaces engines.node with a lower-bound range such as >=24.0.0 when the current declaration does not satisfy the scan. The command rewrites package.json as formatted JSON, so review the diff before committing it.

The fix is available only with --runtime node or the default --runtime all. It does nothing when no Node requirement was detected or the existing range already accepts the required version.

Static analysis cannot see native addons, operational policy, transitive runtime constraints, or tests that intentionally require a newer Node release. Keep a stricter declaration when one of those constraints is real.
