<violation number="1" location="src/commands/auth/login.ts:140">
P1: The validation logic treats any error from `resend.domains.list()` as an invalid API key, which produces false negatives. Valid API keys will be rejected for rate limits (429), server errors (5xx), or permission issues (keys without full_access scope cannot call domains.list()).</violation>
