Clean
Clean names the invariant carrier by which relation remains free from residue, drift, or false mixture before readable difference is carried onward. It is the condition in which relation does not carry what prevents its own readability, handling, separation, or meeting.
Clean is hidden in many successful reads because it is not always the visible operation. Clear reading and tactful contact both depend on it.
Places
Clean places the invariant carrier of undrifted relation before the clear/tact split.
Holds
Clean is held by Relation. Relation must hold before anything can be cleanly read, handled, separated, or met.
Pairs
Relation carries downward into Clean. Clean is an invariant carrier: it holds whether or not the split into readability or handling is visible.
Traces
Nests
Clean nests before the clear/tact split. It is not a category above them; it is the hidden carrier that lets reading and contact remain undistorted.
Reads
Clean becomes recognisable where relation is not carrying unnecessary residue, mixture, or drift into the next condition.
