The author details a bug in their LLM tracking system where a generated sentence incorrectly attributed a score to a model that did not achieve it. The issue stemmed from a property test that only verified if a percentage existed in the data, not if it was correctly paired with the model. A revised test now checks for correct pairing, and the fixture was updated to include multiple cheaper models per lab to better simulate real-world scenarios and expose such errors. This process revealed further bugs related to float truncation and tie-breaking, requiring additional tests for comprehensive coverage. AI
