Builds a persistent flakiness infrastructure dashboard from JUnit XML or JSON CI run history: defines the flake-rate metric (failures per test over a configurable window), authors the data model, generates a Grafana time-series panel JSON or configures a Datadog CI Visibility view, derives the quarantine-candidate query, and wires trend alerts. Use when a team needs a long-lived observability surface for test reliability that outlasts any single weekly report.
