momentum devandClaude Fable 5 bdeb2ec4b4 plans(017): VERDICT — L2 depth is real but too weak; FAIL under real exit + random-gate null
Definitive test, n=2191 real deployed exit: ask-overhang separates +0.083R
(high -0.676 vs low -0.759, direction held sniff->scale = genuinely real) but
fails the random-gate null — it shrinks losses, never creates profit. Live
gap>=10% band n=13/74 = no signal. Same shape as regime gate on a negative-EV
base. 13 conversion levers + regime + depth tested, zero make it positive.
Real-money rec: NO. Depth edge argues for a broader-population redesign as
future research, not a live fix.
