@samteb I feel these types are either redundant with (entity.type.ts) or in the wrong place.

These feel strictly related to how OPA operates, not the engine entities.

[samteb]

Yeah I think you are right. those types seem to be duplicated.
what do you suggest?

[wcalderipe]

@samteb not sure. I feel these types are crafted for optimizing Rego queries, and we should keep them like that.

Maybe we move these to a specific module called open-policy-agent?

Good job Doc'
