This domain is neither of the documented AI providers. Reusing a provider credential for vendor entitlement validation violates credential-purpose binding and least privilege. The remote service receives a reusable secret that may authorize billable AI operations. The behavior is particularly ...[truncated 1393 chars]- Remediation
