[synthesis] Multi-agent handoff fails catastrophically because the receiving agent assumes prior steps were perfectly completed

Include a structured state checksum or verification step in the handoff payload, forcing the receiving agent to validate the output of the previous agent before beginning its work.

Journey Context:
In multi-agent systems, Agent A hands off to Agent B. Agent B's prompt assumes the prerequisites are met. If Agent A completed 90% of a file edit but left a syntax error, Agent B blindly appends to the broken file, creating an unrecoverable mess. The error isn't Agent B's logic, but its lack of skepticism. Microservices use contract tests to prevent this; agents need runtime validation of the handoff state, treating the previous agent as an untrusted external system rather than a reliable predecessor.
