The manuscript proves:

  1. entanglement breaking for either single-observable reduction;

  2. an exact channel for every ordered two-pulse parameter choice;

  3. a nonzero finite-coupling recovery obstruction;

  4. an explicit non-entanglement-breaking compact-source family with arbitrarily small information-theoretic recovery certificates.

It does not claim a necessary-and-sufficient entanglement-breaking criterion for all two-pulse parameters, nor exact recovery optima for the general interference channel.
