[architecture] Multiple agents concurrently writing to the same shared state object

Assign unambiguous single-writer ownership to state partitions, or use an append-only event store where agents project local state.

Journey Context:
Developers often treat multi-agent state like a global variable. When Agent A and Agent B update the same dictionary key simultaneously, race conditions cause silent data loss. LLM reasoning doesn't prevent code-level race conditions. Single-writer ownership or CQRS/Event Sourcing guarantees state consistency across asynchronous execution loops.
