RHY.6:4.3 - Expose collapsed distinctions

Look for two admitted source cases that translate to the same target. If such a pair exists, would the receiving operation need different answers?

When such a pair needs different answers, retain the missing distinction as a target feature or companion representation, or keep the relevant source phrase or recording accessible with a way to locate that distinction. When the answers coincide, that loss is harmless for this operation. Consulting source material to recover missing content is different from interpreting a target answer back into the source question in :4.4. That answer may need the same timing, a compatible performance or the original expression; state which the work requires.

A target with richer notation cannot recover source information that has already been discarded. For a continuous shape reduced to sample points, name the interpolation or reconstruction assumption if the receiver must act between points.
