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

Assign unambiguous single-agent ownership to mutable resources; enforce that other agents request mutations via message passing to the owner rather than direct writes.

Journey Context:
Distributed systems principles apply: concurrent writes to shared state cause overwrites. LLMs cannot natively resolve merge conflicts. Implementing the Actor Model—where state is encapsulated by a single owner agent and modified only through its explicit interface—eliminates race conditions without requiring complex distributed locking mechanisms.
