The physical bridges still required

A physical evaporation interpretation needs three additional objects in the same model:

1. Coherent infalling-code identification. A specified gravitational preparation and insertion must implement every allowed logical matrix unit, including reference correlations. A source register, an eigenstate embedding, or a classical perturbation family is not by itself an infalling diary.

2. Radiation and operational access identification. The asymptotic or collected bath algebra must be related to outgoing physical radiation and to a declared coherent receiver. A CPTP decoder formula does not supply that receiver or its resource schedule. The distinctions recorded in En02-B, En02-C, and Em03-C remain relevant CheungEn02B,CheungEn02C,CheungEm03C.

3. Geometry, backreaction, and endpoint identification. Energy loss must be related to a sourced gravitational evolution with a controlled remainder. The late-time information estimate and the geometric validity interval must overlap. Complete geometric evaporation needs its own endpoint argument.

The low-energy SYK reparametrization sector motivates a nearly-${\mathrm{AdS}}_2$ comparison MaldacenaStanford; it does not automatically identify a full finite-code radiation channel.

Gaikwad, Kaushal, Mandal, and Wadia supply a particularly relevant microscopic evaporation candidate with partial and horizonless complete-evaporation solutions in its stated regime GaikwadEtAl. Their reconstruction of initial spin labels by repeated processes with different couplings is not silently promoted to single-run recovery of an arbitrary reference-entangled diary. Their geometry is also not combined with the present quadratic decoder without a comparison theorem.
