The resulting worldsheet theory possesses three first-class constraints, $C_1 = P^2$, $C_2 = P \\cdot X'$, and $C_3 = P \\cdot X$, whose modes realize a Weyl-BMS algebra. The additional Carroll-Weyl constraint qualitatively changes the quantum gauge complex: its scalar $s$-ghost is intrinsically coupled to the BMS $bc$-ghost sector, and the anomaly analysis involves three independent cocycles rather than a single Virasoro-type central charge.
