[architecture] Race conditions and lost updates when multiple agents mutate the same shared state object

Implement unambiguous resource ownership \(single-writer principle\) per agent, or use an append-only event log with a central reducer to resolve state updates.

Journey Context:
Giving multiple agents write access to the same state dictionary or database row leads to classic distributed systems race conditions. Agent A and Agent B read state, modify it, and write it back; the last write wins, losing A's update. By assigning strict ownership \(only Agent A writes to Field X\) or using append-only reducers, you eliminate concurrent mutation bugs.
