Hi, I’d like to work on this issue. I understand the need for an emergency pause mechanism to protect the contract from exploits. I will implement an admin-controlled pause/unpause system using persistent contract storage, enforce state checks in all critical quest functions, and add comprehensive tests covering paused, unpaused, and unauthorized access scenarios to ensure secure and predictable behavior.
Please assign me to this issue. Thanks!
