Core V3 rule: pivot comes from confirmed swing resistance preceding the final contraction trough. A fresh breakout spike needs future bars before it can become a confirmed swing, so the pivot cannot chase the breakout upward the next day.

Why shadow mode first: Phase 2A ML was trained on the old detector population. Switching stage/pivot definitions without rebuilding historical signals and retraining would create model-population drift.
