A bare workload-identity or Bedrock client could attempt a beta Realtime handshake without applying its configured authentication. Reject those unsupported profiles locally before credential refresh or connection, and enforce the documented X.509 WebSocket exclusion.

Preserve explicit Authorization settings for other clients, including default and connection headers, case-insensitive overrides, and removal with omit. Document this compatibility boundary without adding provider token exchange or signing.

Validation:

• Before the change: 8 refusal cases failed and 16 explicit-header compatibility cases passed.
• After the change: all 24 profile tests passed.
• All 74 focused tests passed, including existing beta Azure and redirect controls; the same 74 passed against a locally built, non-editable wheel.
• Ruff formatting, lint, and diff checks passed.
