Report #56723

[architecture] Downstream agent fails to parse upstream agent's unstructured output

Enforce strict JSON schema contracts at the boundary between agents using structured outputs, rejecting any payload that fails validation.

Journey Context:
LLMs default to free-text. Passing text between agents creates fragile regex/prompt parsing dependencies. Structured outputs make the interface deterministic. The tradeoff is that over-constraining the schema can reduce the LLM's reasoning flexibility, but at agent boundaries, machine-readable state transfer is strictly required to prevent cascading parse failures.
