Internal Libraries

Libraries hold the single source of truth for shared storage and reusable helpers, so every facet speaks the same language.

• AccessControlLib: Packs role flags into a struct at ACCESS_CONTROL_STORAGE_POSITION and exposes modifiers (onlyOwner, onlyGuardian, etc.) that all facets import, guaranteeing consistent checks.

• MoreVaultsLib: Central repository for vault-wide parameters: asset list, fee config, totalAssets cache, and the immutable wrappedNative address. By reading/writing through this lib, facets avoid storage-collision and keep gas costs down.

These two libs are call-only—they cannot hold ETH or ERC-20s—which keeps the attack surface limited to the facets and diamond itself.
