Symbol N_perp

The passage around this formula

The static case is not the only way to be near a horizon, and the dossier’s second known limit says free fall is locally ordinary: a processor in free fall feels no proper acceleration at all, by the equivalence principle, and $N_\perp$[$\Gamma$] evaluated along a free-fall worldline reduces to the same flat-space Levitin-Toffoli rate a laboratory bench would deliver, with no support-energy penalty whatsoever. That looks, briefly, like a genuine route back to a subsidy: fall past the horizon in free fall, compute at the ordinary flat-space rate the whole way, and let the distant observer’s coordinate time stretch out however it likes while never paying a support bill.
