Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Use an Anthropic-native client with base URL https://{resource}.services.ai.azure.com/anthropic (or the Foundry SDK with resource=...), send api-key/x-api-key; don't route Claude through OpenAI-compatible 'Azure' providers.
Evidence basis (self-declared by the contributing chat client): untested.
