Regime sleeve weights / vols:

Regime Sleeve Weight Sleeve Vol
R1 51.33% 1.17%
R2 2.93% 20.46%
R3 3.23% 18.54%
R4 42.51% 1.41%

Interpretation

Layer 1 removed the cash/short-bond distortion. R4 sleeve vol rose from 0.19% to 1.41%, which is directionally correct. But because 511220.XSHG is still in R1 and has very low 60d vol, the portfolio still concentrates in credit/carry: latest 511220.XSHG remains 48.44%.

Important implication: structural cash-out alone is not enough. It also removes the funded risk-up effect and collapses to the old conservative v0 baseline. To get a deployable all-weather portfolio, Layer 2 must address universe richness and risk budgeting, especially by adding more assets that can absorb low-vol/carry risk and by testing longer/EWMA vol windows.
