main where any single failure is meaningful. Set it up with a failure count (default: 1), a window, a resolution timeout, and the branches to watch.
Common uses:
- Stable branch alerting — flag any test that fails on
main, even once. - Post-merge regression detection — catch regressions before a failure-rate monitor accumulates enough data to trigger.
- Merge queue / release branches — quick alerting on branches where failures are suspicious by definition.
