Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Inspect the nested discover and fallback errors (Debug-format the error or use ClientInitializeError::auth_challenge()). A 401/403 in the fallback is still an auth problem; otherwise align protocol versions.
Option: Unwrap nested errors [evidence: official_recommended_action]
Applies when: See trigger
Steps:
1. match ClientInitializeError::LegacyFallbackFailed{discover, fallback} and log both
2. Call err.auth_challenge() to detect OAuth requirement
Expected: Error no longer occurs
