Unknowns

  • What other changes (features, fixes, breaking changes) are included in llm-echo 0.4 besides token-field population?
  • Are input_tokens and output_tokens populated consistently across all supported providers/models, and what are the exact definitions (e.g., include system prompts, tool calls, cached tokens)?
  • Does llm-echo 0.4 change response schemas, logging, or data formats in a way that could break existing integrations?
  • Is there any direct decision-readthrough (operator, product, or investor) implied by these deltas?
