Function monitor 

pub fn monitor(s: &Summary) -> Monitor

The monitor of s (module doc): per session, the doubly robust difference between the policy that ran (its logged propensities) and the fixed rule, each apply’s outcome model fitted without its session’s half (cross-fitting by the parity of the session’s tick), the inverse-probability weights truncated at √N × their mean and normalised per route, a route’s weighted residual in use from ROUTE_LABELS_MIN labelled applies on (the direct-method term alone before); plus α × the fixed rule’s value; per apply, a session’s mean an increment, in session order, under a one-sided time-uniform confidence sequence at DELTA (upper_bound). Trips when its upper bound falls below 0.
