Report #42903

[architecture] Multiple agents modifying the same state resource causing race conditions or overwrites

Implement the Single-Writer Principle by assigning unambiguous resource ownership to exactly one agent.

Journey Context:
Distributed systems principles apply to multi-agent systems. If two agents write to the same database key or state variable, last-write-wins causes data loss. Developers often think LLM intent or prompt instructions will prevent collisions; they won't at scale. Assign strict ownership: only the Database Agent writes to the DB. Others must request writes via structured messaging to the owner.
