Deploy microservices with Certainty

" summary

Shows that consumer-driven contract tests stop accidental production breakage by example: a deployed change removes a JSON field and causes a runtime error and rollback. Uses pact to generate a contract from a consumer test, a stub HTTP server to exercise gateways, and a pact broker or artifact store to share pacts. Pipeline runs consumer contract publish then provider verification against staging and production contracts so deployments pass only when the real provider matches the recorded interactions.
