Report #65410

[architecture] Agent output schema drift causing downstream parsing failures in multi-agent chains

Implement JSON Schema contracts with strict validation at agent boundaries; reject non-conforming outputs before propagation using draft 2020-12 validators

Journey Context:
Loose typing between agents works in prototyping but fails in production when LLM output formats drift. While protobuf offers strictness, JSON Schema hits the sweet spot of rigorous validation while remaining human-readable for debugging nested structures. The alternative of manual regex parsing misses semantic constraints. Accept the validation latency to prevent cascading failures that are orders of magnitude more expensive to debug.
