💡 - could add a catalog option to add build metadata (similar to, e.g., a resource request)

[NeilHanlon]

moreover, why is this happening with this specific spec? can we repro locally outside of Peridot?

I'm not sure this is fully a Peridot problem, rather than a spec problem but I might be mistaken. Let's investigate the problem further.
