In an appropriate large-N and large-p limit, two-point functions and certain four-point probes admit analytic treatment. Boundary correlators determine a generalized HKLL reconstruction of the emergent bulk geometry. Operator size and Rényi-2 mutual information track an infalling excitation. Second Rényi entropy tracks entanglement between the evaporating eta system and the chi bath, including its oscillatory evolution.
