Any given attic space should be fully within or fully outside of the building thermal envelope. If the attic assembly is an unvented type (previously called a conditioned attic), then it should be fully within the building thermal envelope. Unvented attics, as the name implies, should not have attic vents, either at the soffit or the roof.
A vented attic on the other hand should have insulation at the ceiling, not affixed to the underside of the roof decking and should be ventilated. A vented attic exists outside of the thermal envelope.
What you describe is neither fish nor fowl: “spray foam insulation in the attic”, “attic is conditioned” are attributes of an unvented attic; while “evidence of ventilation” is an attribute of a vented attic. If these characteristics do actually coexist in the same attic space, it’s misconfigured and deficient.
