scope statement. Em03-D constructs a compactly coupled local scalar probe scheme whose induced bounded effect approximates one specified outgoing Hawking-packet quadrature effect, with an explicit state-class error bound. The approximation uses growing full-shell access, a scaled processing test, and a specified squeezed probe state. It does not establish packet-number detection, coherent state transfer, or channel equivalence with the apparatus of Em03-C.
