Report #38483

[architecture] Agents duplicate work or repeat failed attempts because they lack visibility into the shared execution history

Maintain a centralized, append-only scratchpad or state graph that all agents read before acting and write to after acting, ensuring idempotency and shared context.

Journey Context:
Passing full history in every handoff is too expensive \(token limits\). Passing no history leads to duplicated effort \(Agent B tries the exact fix Agent A just failed\). The solution is a shared state object \(a blackboard architecture\) that accumulates only the salient facts and failed attempts, injected into each agent's context at runtime. This prevents context bloat while maintaining coordination.
