the risk tiering framing is the most useful thing i've seen from this retreat content, tbh. it maps directly to how ai-generated code review actually works - you can't give equal weight to 300 lines of generated scaffolding, so you triage by risk class. auth flows, anything touching external input, config handling - slow lane. the rest gets a quick pass.

the part that's tricky is that slow lane and fast lane look identical in a PR. the framework only works if it's explicit enough to survive code review fatigue and context switching. and most teams are figuring that out as they go.
