The busiest baseline in the system. Evening peaks in BR are strong enough that a flat mean fires nightly — the hour-of-week fit is what makes it usable.

Deliberately tight at 2σ. A crash regression that hides inside a wide band is the exact failure this tool exists to prevent.

Recomputed monthly against a 90-day window, so it drifts upward with the thing it is meant to detect. A fixed commercial target would be the better instrument here.

Day-of-month seasonality matters — billing runs cluster, and a flat baseline fires on every cycle boundary.

Fixed acceptance floor at 95.0%. There is no band to widen — a coverage threshold is a decision, not a distribution.
Not a fitted baseline — a fixed acceptance floor. Kept in this table so every threshold the tool compares against lives in one place.
