This commit resolves the type mismatch issues in the VerifyMedicalAI smart contract by aligning the method signatures of `record_ai_info` with ARC4-specific types instead of basic Python types. The update ensures type safety and compatibility with ARC4's static type system, preventing build-time type errors. Changes: - Updated parameter types in the `record_ai_info` method from Python builtins to ARC4-specific types, ensuring that the method signatures correctly utilize `arc4.String`, `arc4.UInt64`, and `arc4.Bool` types as defined in the AiInfo struct.

1) What was the problem?
The problem was related to type mismatches in the
record_ai_infomethod signatures of theVerifyMedicalAIsmart contract. The method signatures were initially defined using basic Python types such asstr,bool, andUInt64. This led to compile-time errors because the ARC4 framework requires using ARC4-specific types (likearc4.String,arc4.Bool, andarc4.UInt64) for both defining data structures and for function parameters to maintain type safety and adhere to ARC4's strict type system. The errors were preventing the smart contract from being built, as ARC4 could not correctly interpret these basic Python types in the context of ARC4's static type checking.2) How did you solve the problem?
I solved the problem by updating the
record_ai_infomethod's parameter types from Python's built-in types to ARC4-specific types. This involved changing the function signatures to expectarc4.String,arc4.UInt64, andarc4.Booldirectly, rather than the standard Pythonstr,bool, andUInt64. By aligning the method signatures with the types used in theAiInfostruct, I ensured type consistency and compatibility across the contract. This change addressed the build errors by satisfying ARC4's type requirements, allowing the contract to compile successfully and ensuring that all operations within the contract adhere to the expected type safety standards of ARC4.3) Screenshot of your terminal showing the result of running the deploy script.
