The `PointGuardTaskManager` contract manages tasks and their responses within a specified time window. It allows a designated generator to create tasks, and an aggregator to respond to them. The contract verifies task responses using BLS signatures and quorum thresholds. It also supports challenging task responses within a challenge window and resolving these challenges. The contract is upgradeable, pausable, and includes access control mechanisms.

The `PointGuardServiceManager` contract facilitates the registration and management of protocols within the PointGuard system. It allows a designated `registrationManager` to register new protocols by providing a reference URL. The contract also includes functionality to freeze operators via the `PointGuardTaskManager` and checks if a protocol is registered. Access control is enforced through modifiers restricting function calls to specific roles.
