ISOTOPIC DRIFT
INDEX Diso
A standardized, theory-agnostic forensic metric for identifying isotopic gradients inconsistent with industrial melt-phase mixing. Demonstrated on the Ubatuba fragment. Proposed as a falsifiable prediction for 3I/ATLAS.
THE METRIC RESIDUE HYPOTHESIS
Standard forensic protocols applied to recovered UAP materials typically seek functional components — circuitry, fasteners, identifiable mechanical geometry. This orientation may systematically overlook a distinct class of signature: isotopic gradients inconsistent with any known industrial process.
We propose that certain anomalous samples represent precipitates formed under extreme non-equilibrium conditions. The transition from anecdotal description to predictive materials science requires a standardized coefficient. The Isotopic Drift Index provides that foundation.
The Diso Formula
Iobs = Observed isotopic abundance
Istd = Terrestrial / solar standard
Terrestrial Baseline
Consistent with known industrial melt-phase processing.
Anomalous
Investigate enrichment or contamination sources.
Falsifying Threshold
Falsifies industrial melt-phase mixing as origin.

3I/ATLAS — MACRO VALIDATION
The 2026 encounter with Interstellar Object 3I/ATLAS provides an opportunity for macro-scale application. Remote sensing indicates an extreme NiI/FeI abundance ratio consistent with non-equilibrium dissociation, alongside significant methanol enrichment.
We propose as a testable prediction that high-resolution spectrographic analysis of the object's ejecta will confirm Diso > 0.5 for the Nickel-62 system — proposed as a primary observational objective for the May 2026 Jovian periapsis window.
Fe / Ni ratio — 3I/ATLAS

DATA ACCESS
The Diso methodology is proposed as an open forensic standard. Direct application to raw NanoSIMS datasets — beginning with Powell et al. (2022) — is the proposed next step toward formal validation.
