[synthesis] Data types mutate across multi-agent handoffs causing downstream schema corruption

Enforce strict, schema-validated contracts \(like JSON Schema or Pydantic models\) at the boundaries between agents. Reject any handoff payload that fails validation, forcing the sending agent to retry with correct typing.

Journey Context:
In multi-agent systems, Agent A might output a number as an integer 123. Agent B receives it, but because LLMs natively output strings, Agent B serializes it as a string '123' before passing to Agent C. Agent C writes '123' to a database integer column, causing a silent truncation or crash. The synthesis is that LLMs do not have native type safety, and without rigid inter-agent contracts, data undergoes 'type drift' similar to the telephone game, leading to catastrophic schema failures in downstream systems that expect the original type.
