FORENSIC REVIEW / CASE 054
Three spectral passes were run independently. The absence recurs at the same interval in each.
Room continuity is preserved across every dropout. The carrier is not.
A voice component sits below the identification threshold at 00:04:32. It was not raised, and it is not transcribed.
Recovered headers show no edit boundary at any dropout.
ESTABLISHED: the absence is periodic, and it is present in the source rather than introduced by transfer.
NOT ESTABLISHED: origin, mechanism, intent, authorship.
The measurement is retained. No further inference is entered into this record.
