That which observes change does not participate in change. The witnessing position remains invariant while state varies.
Plate XXI defines the invariant witnessing position. While x(t) varies across body, role, narrative, emotion, and silence, the witnessing position W remains uncarried by the field. Witness is not the contents of awareness and not an object within state-space; it is the stable observational coordinate through which state variation becomes legible. W does not replace I*; it preserves continuity of recognition across changing states. The field changes; the witness remains.
