Trapezoid subsystem code
Trapezoid subsystem code is represented at T1 by Definition 6 member m=5,k=2,l=1 with occupied trapezoid sites and nearest-neighbor row-X/column-Z gauges. The deterministic constructor validates the binary symplectic quotient and derives the displayed operator-incidence view from those same checks. Decoder, operation, and realization facets remain unsurveyed.
