Runtime Supported
endoflife.runtime-supported
Fails if any detected runtime is outside the active support window
(is_supported == false). For products that distinguish active
support from security-only maintenance (e.g. Node.js, Python,
.NET), this catches services running on a runtime that's still
patched for security but no longer receiving non-security fixes.
For products without a separate active-support window (e.g. Go),
this check is equivalent to runtime-not-eol. Skips cleanly when
no EOL data is present.
