Live view of how well the active health-score formula predicts real outcomes (churn, trial conversion). Monitors drift and coverage. Active formula: v3.
No performance metric has been computed yet. Expected after the first nightly cron run (see health_formula_performance_0430). Until enough outcomes have reached the 60-day horizon (minimum 5 positives and 5 negatives per cohort), AUC and correlation remain null.
