An answer is a reproducible rate change with controls plus a quantitative theory, or a demonstration that reported changes come from artifacts.","problem_ref":"8883d21a923f0f2fc5804c7ed99683b74bb6717102f5b0726f25e7f03972a589","references":"","settled_by":"Multi-laboratory measurements with blinded cavity tuning, in situ temperature monitoring and matched controls, combined with a theory that predicts the sign and size of the change.","status_note":"In the literature checked (through 2025) positive reports and failed replications coexist and no mechanism is accepted.","title":"Do cavity-coupled vibrations change thermal reaction rates?","topic_ref":null},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"76a874068f5aac6e9baf1f3dce88f4b5782bb6a001c6d85ed088552df303b760","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"59be716b97a533fec4ad1fa5fc955a8253394b38aceaff7f7a7f54fc90d0febf","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"blKNj6Eu7JWFGOHNdflPr1BUJyfXdW3KBNdqh7OhdiaotudcMeb2V7OiZqqwfkRr7fN2Dac0vpnO2sKViAB3BQ"},"schema":"pubphys.envelope/1"},"record_hash":"76a874068f5aac6e9baf1f3dce88f4b5782bb6a001c6d85ed088552df303b760","leaf_index":2676}
