• Run cargo test -p router-multicall and ensure tests pass

TODO

Role membership transfer between addresses (router-access)

• Add new contract API to transfer role membership from from to to.
• Enforce authorization: caller must be role manager for the role (or super admin if designed that way).
• Semantics: transfer only if from currently has the role active (expired source must error).
• Preserve expiry: destination receives the same expiry timestamp as source.
• Keep storage consistent:
  • Update HasRole, RoleExpiry
  • Update RoleMembers(role)
  • Update AddressRoles(from) and AddressRoles(to)
  • Update RoleMemberCount(role) correctly only when active.
• Add events (either new event topic or emit existing grant/revoke events consistently).
• Add tests:
  • permanent grant transfer
  • expiring grant transfer (expiry preserved)
  • expired source transfer fails
  • destination blacklisting prevents transfer
  • role not present on source fails
  • from == to behavior
• Run cargo test for the affected contract/package(s).
