This is a disabled-by-default example that documents the linux-features
contract. It is intentionally harmless and does not patch the real Codex bundle.
To try it locally, copy linux-features/features.example.json to
linux-features/features.json and add:
{
"enabled": [
"example-feature"
]
}The example feature declares entrypoints.patchDescriptors in feature.json.
Its patch.js exports descriptors that replace a synthetic marker used only
in tests. The example stage.sh is a no-op hook that prints a short message.
