Hank now flags at 60 days, not 90.

We dropped Hank's silent-customer threshold from 90 days to 60. The 90-day default was catching issues too late to save — by 90 days of silence, most customers had mentally moved on.

60 days is the empirical sweet spot in our data: false-positive rate stayed under 15% (customers on vacation, in transition, or doing seasonal work), while save conversations went from 1-in-5 flags to 1-in-3.

Configurable per cohort. New porchops customers default to 60; existing accounts can stay at 90 if their cohort has different patterns.
