Report #49021

[synthesis] Multi-agent handoff drops nullable fields or alters data types causing silent data corruption in downstream agent

Enforce schema validation \(e.g., JSON Schema, Pydantic\) at the boundary between agents. Never pass raw unstructured strings or inferred dictionaries between agents.

Journey Context:
Agent A extracts data and passes it as a JSON string to Agent B. Agent B infers the schema from the sample string. If the sample lacked a nullable field \(e.g., middle\_name\), Agent B assumes it doesn't exist. Agent B then writes a database insert script omitting the column, silently dropping data. By step 7, downstream analytics fail. Structured handoffs force an explicit contract, breaking the telephone game where implicit assumptions compound into data loss.
