  "summary": "On 7 September 2026, an engine test on hosted hardware verified that an opted-in session produced an encrypted transcript readable with the customer’s key, while an opted-out session produced no transcript in the record subsystem. Alteration of a recorded entry was detected. This record explicitly says the feature was not enabled in production. The separate, bounded response-replay cache is outside the transcript subsystem, so the opt-out result is not a claim that no response bytes can exist anywhere. Production enablement requires separately reviewed privacy disclosures and evidence.",
