Interpretive rules
3 interpretive rules
A slower collector receives two applying lights and gathers them into one perfected relation under the medieval collection doctrine.
A third party perfects first and blocks the intended matter, preserving Sahl's broader prohibition family and its cutting-off subtype.
A faster intermediary body separates from one significator and applies to another, carrying the light onward in the medieval transfer-of-light doctrine.
