Piecewise clock discards continuity anchor or active rate · case 03

The decoded time state disagrees with the explicit regression oracle for coordinate.

Member previewVariant 3 · 3 implementations · 11 checks per implementation

Case contract

Virtual clock has anchor A at monotonic M0, rate p0/q0 until switch S, then p1/q1 thereafter. Readings may precede M0 and use first rate. The switch is continuous. Report exact coordinate, active rate, continuity anchor, next target delta and inverse monotonic coordinate for a target at or after switch. All rates positive.

Why this case matters

Clock transfer and timestamp consumers require preserved coordinate, phase, validity and elapsed-time semantics.
