Full source

/**
 * Singleton manager for cloud-provider authentication status (AWS Bedrock,
 * GCP Vertex). Communicates auth refresh state between auth utilities and
 * React components / SDK output. The SDK 'auth_status' message shape is
 * provider-agnostic, so a single manager serves all providers.
 *
 * Legacy name: originally AWS-only; now used by all cloud auth refresh flows.
