[synthesis] Handoff summary between agents drops the exact preconditions checked by the first agent, so the second agent re-checks differently and proceeds on invalid state

Serialize the full decision record at handoffs—preconditions checked, observed values, and tools used—so the receiver can reproduce the check rather than reinterpret a summary.

Journey Context:
Multi-agent frameworks pass natural-language summaries like 'database migration completed.' That omits how it was verified. The next agent re-interprets 'completed' with its own heuristic, often a weaker one, and starts the next step. Adding more agents magnifies the drift. Longer summaries still summarize. The right call is to pass structured decision records as the handoff payload and treat the summary as commentary, not authority. This is the agent equivalent of passing stack traces, not just error messages, across process boundaries.
