Best fit: SaaS teams that already track usage and need customer-facing warning events before a customer hits a plan limit, blocked feature, or unexpected overage.

What this replaces

A custom threshold service, a pile of one-off Stripe webhook handlers, and the brittle support workflow where customers only learn about usage limits after billing or access breaks.

Buyer checks

The delivered kit includes npm test, npm run smoke:buyer, and npm run verify:manifest so a buyer can verify the archive before adapting it.
