Module external_storage 

Storage layouts for contracts that aren’t part of the local project.

foundry_common::external_storage turns a verified source into a storage layout and caches the result; ExternalIdentifier finds that source on a block explorer. This module is the seam between them, and owns the state that has to outlive a single lookup.
