MDPE.17:4.4 - Stop when source material does not yet yield a reusable Method
The Call provides a songbook, exercises, recordings, datasets, choral AI models, an installation, and governance experiments. These are valuable source materials and project results. The project page does not by itself supply one complete reusable Method for a later choir–model project.
Recover or select the needed candidate Method first through direct inquiry or A.3.1.MR/MDPE.18. Then use MDPE.17 only when a receiving choir, organizer, model-development team, or configured performing whole performs representative Work under an admitted receiving Method.
