notessubmitter remarks + registry
Visual inspection inconclusive. Composition cannot be assigned within current reference frameworks. The Raman peak at 612 cm⁻¹ matches the unattributed feature reported in AM-2019-04471-A and AM-2016-00744-A; no structural model has been proposed for the joint occurrence across three specimens of dissimilar provenance. The peak at 870 cm⁻¹ has not been observed elsewhere in the registry. Non-destructive analysis ongoing. Record kept under active observation pending re-submission of supporting documentation.
