What changed
CoPaw PR #5582 addresses issue #5573 by recovering from DeepSeek V4 streaming reasoning_content errors.
Why it matters
Provider compatibility is a recurring reliability risk for AI agent apps. Small schema differences in model streams can break end-user workflows even when model configuration tests appear to pass.
