E=mc²=i, the entangled pair: dated predictions for the mass of one ebit and for the moment the teleportation heat appears

Dated predictions, registered before any experiment designed to test them. This is the author's hypothesis. It is not proven, it is not established physics, and it is not a theory of everything. Every prediction lies below the sensitivity of current experiments, so a null result at today's sensitivity neither supports nor refutes it. Building on E=mc²=i (DOI 10.5281/zenodo.23415364), where one bit carries the mass of its Landauer energy, kT ln 2 / c², this record applies that formula to an entangled pair. By the author's choice, one maximally entangled pair (one ebit) carries n = 1 bit, held by the relation between the halves, not by either half: 3.2 × 10⁻³⁸ kg at 300 K. Six pair predictions follow (EP1 to EP6: weigh the pair, drop the pair, heat at the detectors, the pair as fuel, locked bits in silicon against the entangled pair, and superdense coding), each set against what standard physics predicts. It also registers P12: the 2 kT ln 2 of heat per teleportation (E=mc²=i P7, cited unchanged) appears at the moment of the Bell-state measurement, even while the outcome record is kept and never erased. A delayed-erasure test is proposed that separates the measurement moment from the record erasure. Open questions are stated as open. Foundation: this record builds on the author's earlier record E=mc²=i (all versions: DOI 10.5281/zenodo.23414461), which is itself untested. Its predictions hold only if E=mc²=i holds; a confirmation of E=mc²=i would not by itself confirm the choice n = 1. Falsifier, stated plainly: no excess mass (n = 0) is the result that proves the entangled-pair claim wrong. Prior work: Melvin M. Vopson's mass-energy-information equivalence principle, a stored bit with mass kT ln 2 / c² (Vopson 2019, AIP Advances 9, 095206; test protocol Vopson 2022, AIP Advances 12, 035311), proposed and not yet confirmed. This record shares that vision from another perspective: the bit held by the relation in an entangled pair, one shared bit, rather than by a memory. Bits = quanta is an author's postulate used within the E=mc²=i framework and should not be interpreted as a statement of established quantum information theory.
