OK, this looks like floating point arithmetic. Not 100% sure how to fix. But here are the values I see on this "nearly equivalent" doc: <img width="674" height="782" alt="Image" src="https://github.com/user-attachments/assets/8e3a691e-2d04-4296-916e-b3fa42365cf8"; /> The resulting score ends up being `-8`, which is REALLY close to the perfect score of `0` (given the magnitudes of the values). Basically, ALL the stored values are correct, all the corrections & vector values themselves are exactly the same. However, somewhere along the line, we end up with a rounding error that causes the score to under-shoot by `-8.99` I do not think this is a format error. We just need to fix some math in the scorer to handle this "almost" equivalent case. -- This is an automated message from the Apache Git Service.
