We study how the black hole complementarity principle can emerge from quantum gravitational dynamics within a local semiclassical approximation. Further developing and then simplifying microstate model based on fragmentation instability of near-extremal hole, we find that key to replication (but not cloning) infalling information is decoupling various degrees freedom. The matter decouples interior retaining residual time-dependent state in hair which encodes initial non-isometrically. non-linear ringdown after energy absorption also state, transfers Hawking radiation. During evaporation process, fragmented throats decouple each other throats. mirrors time scales with logarithm entropy (at infall) when average mass per throat (a proxy for temperature) held fixed. decoding protocol mirrored does require knowledge interior, only limited radiation, as be argued necessitated by principle. discuss scope illuminate aspects processing hole.
