notessubmitter remarks + registry

Three independent analytical passes have failed to converge on a defect model for this specimen. The 612 cm⁻¹ Raman feature is present, the long-lived photoluminescence component is present, and an anomalous magnetic susceptibility is present, but no published mechanism reconciles all three within a single composition. Record kept open at registrar's discretion.
