Erratum (2026-07-06): the TruthfulQA result cited as "up to +2.8pp" did not survive controlled replication (McNemar p = 0.22; see DOI 10.5281/zenodo.21206458) and should not be cited as an effect. The disclosure's methods and priority dates are unaffected. Defensive technical disclosure establishing prior art for toroidal coherence methods across four domains: AI hallucination reduction via logit bias, quantum dephasing suppression via Tonnetz spectral gap filtering, topological error correction via toric code, and distributed post-quantum attestation. Includes experimental validation on TruthfulQA (4 models, up to +2.8pp improvement) and theoretical framework for room-temperature quantum coherence.
