Representative validation narrative

Hypothesis: Dual-input AND gate produces output O only when both I1 and I2 exceed threshold concentration.

Model setup: Dual toehold architecture, blocking strand protecting output domain, leak pathway modeled.

Control conditions: no input, I1 only, I2 only, I1 + I2.

R_correct = k_{I1,I2}
R_leak = k_spurious
R_correct >> R_leak

Observed results: [INSERT ACTUAL OUTPUT CONCENTRATION DATA]. Quantitative metrics: leak probability [INSERT VALUE OR RANGE], convergence time [INSERT TIME RANGE], output dominance ratio [INSERT RATIO].

Boundary condition: leak amplification increases as cascade depth rises beyond modeled threshold.
