Demand specific details: What oversight tool? Was it eliminated by statute, court ruling, or administrative action? What agencies are now unmonitored?
This event lacks critical specificity: which oversight tool was lost, through what mechanism, and with what concrete consequences? The summary provides only a vague assertion about 'norm erosion' without identifying the actual institutional change. The mechanism is listed as 'norm_erosion_only' with no enforcement action, personnel change, or policy lever described. Without verifiable details about what specific congressional authority or practice was eliminated, this cannot be scored as substantive constitutional damage.
