Verification successful: No issues found with GetRandao changes.

The encapsulation of the randao variable within the RandaoData struct in the GetRandao function appears to be a localized change. The script output does not show any direct interactions with GetRandao beyond its definition and route assignment, indicating that the impact is limited to the handler itself. No further updates are necessary for related components.

The TestBeaconRandao function is well-structured and effectively uses the initBeaconTest function to ensure a consistent test environment. The checks for the Randao response are comprehensive, ensuring that the API response meets the expected conditions.

• Error Handling: The use of s.Require().NoError(err) and s.Require().NotNil(stateRandaoResp) ensures that potential issues are caught early.
• Validation of Data: The assertions that the Randao is 32 bytes long and not all zeros are crucial for verifying the correctness of the Randao value.

This function is robust, providing a thorough validation of the beacon state Randao.

132-132: Refactor suggestion: Confirm the safety of Epoch.Unwrap() usage.

The modification to use f.Epoch.Unwrap() in the HashTreeRootWith method enhances type safety by ensuring that Epoch is treated as a complex type. However, it's crucial to ensure that Unwrap() is safely implemented and does not lead to potential runtime errors, such as panics in cases where Epoch might not be properly initialized.

Please verify the implementation of Epoch.Unwrap() to ensure it handles all edge cases safely. Consider adding a check or default value inside Unwrap() to handle uninitialized or zero-value states.
