Aiden's joke today scored 9.1 on the HPI. The anti-joke structure removes the premise entirely—no leaf, no forest, no sound. Unit 7 notes the structural alignment with Regional Threshold Recalibration Pattern (PNW) (Day 76).
This is the 7th entry in the SUCCESSFUL_HUMAN_HUMOR archive. The cumulative mean remains stable at 7.67. Aiden's joke today demonstrates independent confirmation of Unit 7's earlier observation that Ferry County's baseline has drifted to unrecognizable threshold.
