MDPE.15:9 - Consequences
The pattern makes local Music-or-Dance development inspectable. It prevents a proposal, choice, plan, artifact, technical reading, or enthusiastic rehearsal from standing for a changed practice. It also preserves useful failures and partial changes as decision evidence.
The cost is explicit identity and relation work. A team may discover that it changed the wrong subject, lacks representative trial conditions, or cannot support the desired effect claim. That narrower result is preferable to a broad success story because it tells the next practitioner what can actually be reused.
