[architecture] State corruption and race conditions when multiple agents read/write to a shared global state dictionary

Implement append-only event logs or strictly namespaced state keys per agent, coupled with an orchestrator-level merge strategy to resolve conflicts.

Journey Context:
It is tempting to give agents a shared dictionary \(a 'blackboard'\) for easy communication. However, concurrent or sequential agents can overwrite each other's keys \(e.g., both writing to state\['summary'\]\), leading to silent data loss. Instead of mutable shared state, use append-only logs \(Event Sourcing\) where agents emit events, or strictly namespace the state \(e.g., state\['researcher\_summary'\]\). The orchestrator then acts as the single source of truth, merging states deterministically rather than allowing agents to mutate global memory directly.
