DAML contract questions about limitations

   Can a Daml contract support a state flag that is both publicly observable on-chain and exclusively bound to a single counterparty or issuance event meaning that once a token enters that state, the binding is legible to any third party inspecting the contract, and the same token cannot enter the same state a second time without first exiting it through a defined release path?
   
   Does Canton's architecture support atomic state transitions initiated by a cross-chain message from an EVM-side event specifically, where a single transaction simultaneously releases a bound state on a Canton-side contract and unlocks the underlying asset, with the trigger originating externally rather than from a Canton participant?
