📄 Description

RemoveLayers was calling Manifests() for each layer to check if it was shared with other models. For models with many blobs (e.g., tensor models), this caused O(N*M) manifest reads. Now loads manifests once and builds a set of in-use digests. Our existing tests should cover this case well
