– No Self-Reduction for LSN
Conjecture 5.20 of the source. It proves no random self-reduction exists from an arbitrary worst-case QNCP instance into LSN, naming exchange symmetry between code and error as the obstruction, and proves the tableau-randomizing barrier conditionally on the scrambling gap being polynomially related to \(\varepsilon\). It is explicit that this is not an impossibility for random self-reductions in general. 4 open
