Report #9779

[architecture] Two agents update the same shared state or resource simultaneously, causing race conditions or lost updates

Implement unambiguous single-agent ownership for every shared resource; other agents must request mutations via messaging to the owner agent rather than writing directly to the shared state.

Journey Context:
Distributed systems principles apply directly to multi-agent systems. Shared mutable state without locks or ownership leads to non-deterministic bugs where Agent A's write is overwritten by Agent B. By treating agents as Actors that own their state, consistency is guaranteed. Tradeoff: increased latency due to message passing instead of direct DB writes, but eliminates race conditions and makes state mutations auditable.
