[architecture] Multi-agent handoff silently drops task context and repeats or contradicts work

Persist a shared, versioned state object with explicit ownership fields; hand off state IDs and checkpoints, not natural-language summaries.

Journey Context:
Teams often hand off by dumping chat history into the next agent's prompt. That compresses away preconditions, tool outputs, and failed branches, so the receiving agent re-derives intent or retries steps the first agent already attempted. A shared state object with an 'owned\_by' field and an append-only event log makes handoffs deterministic and auditable. The tradeoff is extra schema design; the alternative is brittle prompt engineering that fails as soon as tasks loop or fail.
