I Luk Kim 3c13c9e1b5 Add vix_pead regime sizing mode and macro experiments (v6new.19-21)
New in allocator.py:
- vix_pead mode: boosts sizing at VIX>18 (PEAD favorable), penalizes VIX 15-18
- Fixed vix_scaler application to support boost (scaler > 1.0)

Results:
- v6new.19 (spy_qqq risk_off=0.55): SQS 62.8 — reduces size in favorable PEAD regime
- v6new.21 (vix_pead boost+penalty): SQS 46.9 — penalty too aggressive, kills trades

VIX signal is real (62.3% vs 48.2% WR) but sizing alone can't capture it:
- Boosting doesn't help because same trades just get bigger
- Penalizing shrinks or drops trades, losing count
- Need the signal in TRADE SELECTION, not just sizing

v6new.9 (SQS 63.3) remains best.
