Calibrator Changelog

Every change to how the Compass reads.

This is the change history of the calibrator itself: the rules it applies, the reading lenses it gained, and the versions of the law beneath them. Each entry is a change to how the instrument reads, with the case that forced it. It is not a record of any one song's score changing -- that per-song history lives with each product that uses the Compass. This is how the instrument that does the scoring has changed over time.
