Tiwari dates the hypermomentum challenge's technical content to Iosifidis & Hehl (2024), with the underlying tension latent in gauge-gravity literature since Hehl et al. (1995)

Kartik Tiwari frames the "hypermomentum challenge" as having deep roots in the gauge-gravity literature rather than being a wholly new observation. In his own words: "This incompatibility is sourced from what I call the 'hypermomentum challenge', whose technical content was first made explicit by Iosifidis and Hehl [2024], though the underlying tension has been latent in gauge gravity literature since Hehl et al. [1995]." The 2024 paper is Damianos Iosifidis and Friedrich W. Hehl's "Motion of test particles in spacetimes with torsion and nonmetricity" (Physics Letters B 850:138498); the 1995 paper is Hehl, McCrea, Mielke and Ne'eman's foundational Physics Reports review, "Metric-Affine Gauge Theory of Gravity" (arXiv:gr-qc/9402012), which established the MAG framework itself.

This is a priority claim — who said what first, and when a tension became explicit rather than merely present — and it currently rests on a single layer: Tiwari's own characterization of the two earlier papers, not a direct read of either. Neither the 1995 review nor the 2024 paper was independently fetched this session.
