Report #12812

[architecture] Agents maintain separate, divergent states of the shared world, leading to contradictory actions

Use an append-only shared ledger or blackboard architecture for state, where agents read from the source of truth and append their changes, rather than maintaining internal mutable state that they try to sync.

Journey Context:
Passing state back and forth via messages leads to version skew and lost updates. A blackboard decouples agents. Tradeoff: Blackboard can become a bottleneck or context-bloat if not summarized, but ensures consistency and allows agents to react to global state changes without direct message passing.
