[architecture] Context window overflow when trying to maintain global shared state across all agents

Use a blackboard architecture or structured scratchpad where agents read/write concise, structured facts rather than passing full conversation histories between each other.

Journey Context:
Passing the entire chat history between agents quickly exhausts token limits and degrades LLM performance \(lost-in-the-middle\). A shared structured state \(blackboard\) allows agents to read only the specific keys they need and write concise updates. The tradeoff is that agents lose nuance from previous conversational context, but they gain massive token efficiency and avoid context window crashes.
