Report #42332

[architecture] Cascading failures from malformed outputs passing between agents

Enforce strict OpenAPI/JSON Schema validation at every agent handoff using generated Pydantic models with strict mode enabled

Journey Context:
Dynamic typing allows semantic errors to propagate downstream where they're harder to debug and require complex compensation logic. Static schema validation at boundaries catches contract violations immediately \(fail-fast\), enabling early failure and clear error attribution to the producing agent. The tradeoff is rigidity: schema changes require coordinated deployment. Mitigate with forward-compatible schema evolution rules \(only adding optional fields\).
