  "description": "S6 guard: effectiveFloor = min(actionProbabilityFloor, 1/n). With n=3 allocations and floor 0.5, the applied floor is capped at 1/3 (never 0.5, which would demand > 100% of the probability mass). Each below-floor probability is raised to 1/3 and the vector is renormalized. An SDK that used the raw 0.5 floor would produce a different distribution.",
