Evidence drawn from this source

Qualifies· moderateORCH-E072

what the source states: The radiative lifetimes are stated to be defined within the Markovian model: "the lifetimes reported here are defined within the Markovian radiative-loss model" used throughout the paper.
what we infer: My inference: the field has moved to entanglement-flavoured observables without moving to a physiological environment — no solvent, ionic or vibrational bath and no 310 K dephasing estimate. So the class of work that most resembles the witness ORCH-R001 asks for still does not supply the number, and the absence recorded at ORCH-C010 is untouched.
limitations: Preprint; computational only.
Single-excitation manifold, radiative loss only; no non-radiative or thermal channels.

what the source states: The physical decay rates come from the imaginary part of the effective generator's eigenvalues, which "corresponds to a memoryless (time-independent) coupling to the electromagnetic bath" and yields exponential decay envelopes for each collective mode.

Context· weakORCH-E055

what the source states: In the discussion the authors write that their initial-state comparison "does not imply that microtubules must use quantum correlations for neural processing"; rather, it shows that a structured tryptophan network routes dynamics differently depending on how an excitation is prepared.
what we infer: This is the cleanest proponent-adjacent statement in the record that the 2026 photophysics results do not bear on the consciousness attribution. It carries no weight for or against the truth of ORCH-C001; it is recorded because the absence of such a disclaimer is often what the public argument relies on.
limitations: A statement of scope by authors, not evidence about microtubules.
Zero diagnosticity for the headline thesis.
