Detects Q-gap plateau (5 consecutive frozen epochs), rewinds to best-improvement checkpoint, applies perturbation strategy cycle: 1. Reset Adam momentum 2. Shrink-perturb branch heads 3. Temperature boost (2× for 5 epochs) 4. Learning rate boost (2× for 10 epochs) 3 rewinds × 4 routes = 12 max attempts. On exhaustion: save best model, exit with PLATEAU_EXHAUSTED. Saves ~3 hours H100 vs frozen training. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
