A fund's yield is a near-constant in return space, so OLS puts it in the intercept (alpha_ann), not in the shv/bil betas (which only measure rate-CHANGE sensitivity). Cash funds therefore showed no dominant driver. - factors: cash_yield() (shv trailing-1y total return = local stand-in for the 13-wk T-bill / 0-3m Treasury index), AXES = DRIVERS + ['cash'] (alpha_ann / cash_yield, 1.0 = earns the cash rate); a display/clustering axis, not a regressor. - cluster: cash column in the loading matrix; k-means distances use the cash-2x-emphasized matrix (a pure cash fund's level axis was otherwise swallowed by the low-exposure cloud); labels use raw values; label() cash-aware (0.25 threshold, 1.5x runner-up). - app: cluster view over AXES with the emphasized distance. The 331-fund 'no dominant driver' grab-bag now splits into 'cash (yield) +0.64' (n=187, MM + ultra-short) and 'cash (yield) +1.26' (n=59 pure). 123/123 tests.
