Weekly reading · methodology v0.6
Window ending Dec. 15, 2025
Harms count in full for two weeks after they are reported, then one level less every two weeks. The control floor looks at reports from Nov. 16, 2025 through Dec. 15, 2025. A selected catalogue of reported AI incidents, reviewed through Oct. 7, 2026. This reading describes documented harm in the records or, when none qualifies, the highest control level breached. It is not a forecast or a measure of all AI activity.
