Candidate C: static spectra and mutual information

This is an underdetermination statement over unspecified realizations. It does not exclude reconstruction after a sufficiently restrictive dynamical and intervention model is independently declared.

Static area-law records provide the corresponding documentary negative control in Oai265-A: an entropy record is not a recovery channel, a radiation history, or an operational metric extraction CheungOai265A (thm:separation). A geometric partition or an area appearing in a supplied formula must not be treated as geometry derived from that formula.
