Report #55015

[architecture] Agents operating on stale state because they only read initial context and miss updates from other agents

Use a centralized, append-only state object \(like a scratchpad or global store\) that is injected into every agent's context at the start of their turn.

Journey Context:
Point-to-point messaging creates hidden state. If Agent A updates a shared variable and tells Agent B, Agent C is left out. A shared global state \(a blackboard architecture\) ensures all agents operate on the latest truth. The tradeoff is larger context windows, but it prevents the cascading bugs of divergent mental models.
