Fact 369
Riley Tanaka identified a separate source of noise in the onboarding v2 read: the segment job classified some 50–75-seat accounts as mid-segment, and the onboarding send used stale membership from the cache window, producing an incorrect denominator.

ok so I walked Priya through an additional source of read noise, not a different root cause. the CS auto-nudge outage still explains the Apr 17 dip; separately, the segment job was classifying a chunk of 50-75 seat accounts as mid, then the onboarding send was reading stale membership off the cache window. so v2 looked noisier than it was bc the denominator was wrong before you even got to retention. Priya's take was basically good catch, tell Marcus before Friday so he doesn't spin up a whole narrative off the bad cut. I said yep. updating the cohort note to 75-200 and adding the cache timing bit in the doc.
