I put this checklist together after digging into the CrowdStrike "Channel File 291" crash. Basically just tried to map out the specific gates (like N-1 validation and negative fuzzing) that actually would have caught the bug before it hit prod.
If anyone is interested in the visual breakdown of how the failure propagated, I recorded an analysis here: https://www.youtube.com/watch?v=D95UYR7Oo3Y
Curious what other hard gates you folks use for kernel/driver updates.
