Averaging symmetric Z_N quantum circuits over random noise produces a noisy surface code whose logical information is protected against symmetric errors up to a threshold, with charge-sharpening transitions coinciding with bulk confinement transitions that differ for N≤4 versus N>4.

An entropy-corrected action principle on superspace recovers the Wheeler-DeWitt equation for gravity and a Schrödinger equation for coupled scalar fields with emergent time and a G ħ² correction term.
Bilocal holography yields a remarkably local bulk reconstruction formula that agrees with standard methods once boundary data and gauge-fixed variables are matched, while clarifying subregion duality.
