C-0023 Under review MODERATE certainty
The positive-energy warp programme, priced on its own terms: Lentz (2020) asserts superluminal solitons from purely positive energy densities; Santiago-Schuster-Visser (2022) rebut Lentz, Bobrick-Martire and Fell-Heisenberg collectively — each 'merely asserts the existence of one sub-class of timelike observers for which the energy density is positive', which does not establish the WEC — and exhibit boosted observers who see negative density. What survives unrebutted in the corpus is explicitly SUBLUMINAL: Bobrick-Martire's positive-energy class ('any warp drive requires propulsion') and the 2024 constant-velocity solution, which satisfies the energy conditions by adding a positive-ADM matter shell. Consistently, the 2026 certifier finds the irrotational Lentz/Fell-Heisenberg-class geometry globally Type I while vortical walls are Type IV. The surviving programme is subluminal shells with shift — rockets in geometric dress — and superluminal positive energy remains asserted, contested, and unpriced.
Standing peer reviewed contested · interpretation · TRL 1 Assumes the corpus as of 2026-08-07: S-0013/S-0014/S-0015 for the proposals, S-0001 for the rebuttal, S-0003 for the Type classification; 'unrebutted in the corpus' means exactly that — an absence in twelve-plus-three sources, not in the literature at large Stops applying any future peer-reviewed WEC-for-all-observers demonstration for a superluminal configuration, which is precisely what the corpus lacks Note Closes PDB-21 and the FH/Lentz/B-M leg of PDB-24. The VDB leg was priced in C-0010/C-0020.

…ization. As a cautionary example regarding application of the energy conditions, note that all three of the recent Lentz, Bobrick-Martire, and Fell-Heisenberg articles merely assert the existence of one sub-class of timelike observers for which the energy density is positive. This is not enough to show that the WEC is satisfied. To explicitly see a specific example of this behaviour, let us work in an orthonormal basi…
