Report #58833

[architecture] Silent schema mismatches breaking agent chains in production

Implement Pact-style consumer-driven contracts: the downstream agent \(consumer\) publishes a Pact file declaring required schema fields; the upstream agent \(provider\) runs Pact verification in CI to ensure backward compatibility before deployment.

Journey Context:
Traditional OpenAPI specs are provider-centric and drift. In multi-agent systems, agents are independently deployed microservices. Integration tests are too slow for fast-moving agent chains. Consumer contracts shift the burden: consumers dictate the schema, providers verify. Trade-off: you cannot add mandatory fields without consumer consent, slowing iteration but preventing outages.
