"""Unit tests for AZ-325 :class:`CacheProvisionerImpl`. Covers AC-1 .. AC-16 from the AZ-325 task spec plus a Protocol conformance check and the NFR-perf-coverage-walk benchmark. The collaborators are real where they are pure (real :class:`ManifestBuilder` + :class:`Ed25519ManifestSigner` + :class:`Sha256Sidecar`) and faked where they require GPU / FAISS (:class:`EngineCompiler` + :class:`DescriptorBatcher`). The fakes write the same on-disk artifacts the real impls would so the warm path's idempotence check exercises the real Manifest reader.
