1. Responses SSE compatibility

• 1.1 Add a failing client behavior test for a streamed text response with final metadata and usage.
• 1.2 Add failing configuration and client behavior tests for selecting non-streaming Responses transport.
• 1.3 Route Responses requests through the Agent Framework/OpenAI SDK streaming or non-streaming adapter according to configuration.
• 1.4 Add behavior coverage for streamed function-call output.

2. Invalid tool-argument recovery

• 2.1 Add a failing agent-loop behavior test proving malformed function-call JSON does not invoke the tool and is returned to the agent.
• 2.2 Preserve argument parse failures on function-call content and add the shared guarded function invoker.
• 2.3 Apply guarded function invocation to the summary and workflow-editor agent pipelines.

3. Verification

• 3.1 Refactor the touched response and invocation paths for DRYness, SOLID boundaries, and simplicity while preserving behavior.
• 3.2 Run focused tests, the full solution tests, and strict OpenSpec validation.
• 3.3 Verify the client behavior against the deployed LiteLLM Responses endpoint and restart Meeting Assistant only after confirming it is idle.

4. Responses message-item compatibility

• 4.1 Add a failing client behavior test proving an outbound chat message retains the message discriminator through SDK serialization.
• 4.2 Emit the Responses message discriminator for chat message input items.
• 4.3 Run focused and full tests, validate OpenSpec strictly, restart while idle, and retry the failed summary through the local API.
