Core Thesis
Chord confidence drops are not necessarily errors. They often mark the exact moments where a record becomes harmonically interesting, layered, or productively unstable.
What the briefing isolates
How to read the places where chord confidence falls as the arrangement becomes denser or more harmonically adventurous.
How to read the operating range
Low confidence during static loops usually points to blur. Low confidence during intentional harmonic lift can indicate real sophistication. The benchmark should help you separate those two cases.
Where teams should use it
This is useful in bridge review, arrangement cleanup, and education contexts where the goal is to distinguish richness from harmonic fog.
