Performed full review of 852af5e...c41ac05

Analysis

1. The multi-step authentication flow is complex (handoff codes, JWT exchange, multi-factor authentication) and may require additional documentation or usage examples to ensure proper implementation.

2. The RunDiscoverParams is defined as an empty interface but used as an optional parameter, which could lead to confusion without clear documentation about its purpose (whether for future extensibility or API consistency).

3. All tests for this feature are currently skipped, including integration tests that would be critical for validating the authentication flow in real-world scenarios.
