Preview exactly what zeromind.install WOULD write, without writing anything. Returns the resolved closure tree — every file and dependency with its local dest_path, byte size, content hash, and why it is included (root / requires / depends_on / conforms_to / tree_child) — plus rollup totals, a truncated flag and a withheld flag (true when part of the graph lives in a world you cannot read and was left out). Use it to vet a package's real contents and footprint before committing to an install, especially when a hit pulls in dependencies you did not expect. Needs no connected world.
