[architecture] Silent schema drift causing cascading validation failures in multi-agent pipelines

Implement strict JSON Schema validation \(Draft 2020-12\) with semantic versioning at every agent boundary; reject payloads that fail validation rather than coercing types, and maintain a schema registry with backward-compatibility checks in CI/CD.

Journey Context:
Teams often start with 'duck typing' between agents to move fast, but this creates a 'fail slow' mode where schema mismatches propagate downstream, causing expensive retries or hallucinations in later agents. The alternative—loose validation—fails to catch breaking changes during deployment. Strict schema contracts trade initial velocity for reliability, ensuring that 'garbage in' is rejected at the boundary rather than amplified. Versioning is critical: without it, rolling updates of agent A can break agent B that hasn't deployed yet.
