Can we avoid caching 2X manifest files here? As we return std::span for different manifests, perhaps we can use a single vector to store data manifests in the head and then delete manifests in the tail, and then use the split point to construct different spans to return.

If we have to add ctor to it, what about removing the default ctor and adding ctor for all member variables and Snapshot::Make for validated object creation? The Java BaseSnapshot has two ctors for v1 and others respectively.
