A semiclassical construction reproduces Penrose's rate exactly and fixes the constant at 1/2

what the source states
Diósi reports that the least-decoherence semiclassical construction he developed with Tilloy — continuous hidden measurement of the mass distribution, fed back as a classical Newton potential — "confirms the heuristic proposal and makes the constant unique", with the superposition decaying at exactly the conjectured rate "with the unique prefactor const. = 1 / 2".
what we infer
My inference: this narrows the sharpest form of the escape at ORCH-E019. At least one dynamical realization lands on Penrose's own rate, so 'the tested model was never Penrose's' becomes a claim about which dynamics, not about whether any dynamics reproduces the relation. Whether that particular dynamics is itself already excluded by the bounded channels is the open question.
limitations
  • Secondary description of Tilloy & Diósi, Phys. Rev. D 96, 104045, which was not retrieved in this pass.
  • Whether this construction predicts radiation or momentum diffusion at levels the Gran Sasso, Majorana and LISA Pathfinder bounds reach is not stated.

an honest empty state

This claim is in the ledger but not in the current edition's featured set. Nothing here has been assessed — that absence is information, not an oversight.

Still missing: plain-language gloss, credibility assessment, diagnosticity assessment, strongest objection, what would change our mind. A claim gains them when an edition features it and the edition's adopted assessment supplies the full treatment — a decision the panel reviews, not a field anyone flips.
