Report #68491

[architecture] Agents in a swarm operate on stale or divergent shared state leading to conflicting actions

Implement an append-only event sourcing model for shared state, where agents read from a materialized view but commit immutable events, preventing overwrites and ensuring state consistency.

Journey Context:
Passing full state dictionaries between agents leads to race conditions and lost updates if two agents modify the same key concurrently. Event sourcing ensures all agents see the same history and can rebuild state deterministically. Tradeoff: increases storage and requires agents to handle event replay, but solves the distributed state synchronization problem.
