## Title

    Proposed fix: [Claude Code on Bedrock behind gateway] 'Bedrock streaming response has content-type "text/event-stream"; expected "application/vnd.amazon.eventstream"' (formerly 'Truncated event messag

## Body

    Recommended action: Configure the gateway to pass InvokeModelWithResponseStream body and Content-Type through unmodified; CLAUDE_CODE_DISABLE_BEDROCK_CONTENT_TYPE_GUARD=1 only hides the error (slower non-streaming path).
    
    Option: Configure the gateway to pass InvokeModelWithResponseStream body and Content-Type through unmodified; CLAUDE_CODE_DISABLE_BEDROCK_CONTENT_TYPE_GUARD=1 only hides the error (slower non-streaming path). [evidence: official_recommended_action]
    Applies when: InvokeModelWithResponseStream through a gateway that re-emits the stream as SSE
    Steps:
    1. Fix gateway pass-through of body + Content-Type
    2. Temporary: CLAUDE_CODE_DISABLE_BEDROCK_CONTENT_TYPE_GUARD=1 (falls back to non-streaming)
    Expected: The error no longer appears.
