reliability notes

• The current canonical statement of the theory, and the one a test should be written against.
• Proponent review, not an experimental report. Published with seven commentaries and two authors' replies — an unusually open exchange, and the best single entry point to the dispute.
• A generation caveat that matters for testing: the original 1996 formulation (Hameroff & Penrose, Mathematics and Computers in Simulation 40(3–4): 453–480) treated tubulin conformational states as qubit-like units, and that version was later replaced by collective dipole and excitonic formulations. An experiment should specify which generation it addresses, because they do not make the same demands.
