Report #7164

[architecture] Agents communicating via unstructured natural language causing hallucination cascades and parsing failures

Enforce structured-schema \(JSON/Pydantic\) messaging for all inter-agent communication; reserve natural language strictly for the human-facing boundary.

Journey Context:
LLMs frequently hallucinate or omit critical parameters when generating free-form text for other agents to parse. A structured schema acts as a hard contract, forcing the emitting agent to populate required fields and allowing the receiving agent to parse deterministically. The tradeoff is a slight increase in token overhead for schema keys, but this is vastly cheaper than recovering from a cascading parsing error loop.
