3I/ATLAS: A Unified Framework and Live Test for Field‑Mediated ISO Dynamics

This work presents a time‑sensitive, phenomenological analysis of the interstellar object 3I/ATLAS, based exclusively on publicly reported observational data. The paper first enumerates a comprehensive set of observational constraints and evaluates the extent to which existing cometary, sublimation‑driven, and random‑trajectory interpretations account for them simultaneously. A minimal field‑mediated framework (TEIO) is then introduced at a descriptive level to illustrate how coordinated, testable predictions arise without fine‑tuned material assumptions. The forthcoming Jupiter encounter provides a near‑term observational test that will constrain all considered frameworks; the paper is intended to facilitate that evaluation, not to assert a predetermined outcome.
