[Results to be created this time] Compare requirements, current code, and observation results to distinguish between confirmed facts and causal hypotheses. Please trace the affected call path and suggest the minimum replay or log to support our hypothesis. Don't assume there are files or APIs that aren't provided. [Working Principle] Give priority to facts confirmed in the current environment and provided code. Don't create APIs/files/tests that don't exist.
