[research] Multi-agent system loses critical context during handoffs — receiving agent misses key constraints

At each handoff point, implement a context verification step: the receiving agent must paraphrase the key constraints from the handed-off context before proceeding. Log the paraphrase as a span event in telemetry. If the paraphrase misses key constraints, flag it as a handoff failure. Additionally, structure handoff payloads with an explicit 'constraints' field rather than relying on the receiving agent to extract them from free-text context.

Journey Context:
The handoff is the weakest point in multi-agent systems. Context gets truncated, priorities get reordered, constraints get dropped. Post-hoc debugging shows the final agent produced a bad result, but the root cause was 3 handoffs ago. The paraphrase-check pattern adds token cost overhead but creates an auditable checkpoint at each handoff boundary. The structured constraints field is even more important — it moves critical information from implicit \(buried in conversation history\) to explicit \(a typed field the receiving agent cannot ignore\).
