Unified plan combining Sub-plans B+C + novel findings: 1. Fix c51_alpha ramp (eliminate 3 graph recaptures) 2. Per-branch epsilon (magnitude 2×, Boltzmann for order/urgency) 3. IQN quantile spread as anti-collapse bonus 4. Hindsight magnitude relabeling 5. Gradient vaccine with diverse batches 6. Ensemble variance at inference 7. Per-branch bottleneck width 8. Full verification + deploy Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
