Sales trigger watch

Standing trigger taxonomy for sales teams, recomputed on every ingest: EXIT (a competitor left plans or counties), STAR (a carrier's weighted rating sits below the 4.0★ bonus threshold), BENEFIT (modeled benefit value cut beyond 10%, labeled modeled). Each trigger links to the page a rep or sales-ops analyst would act from.
