[architecture] Multiple agents overwrite the same file or state simultaneously causing race conditions

Implement unambiguous resource ownership where only one agent holds the write lock for a specific file or state key at a time, routing concurrent writes through a single reducer.

Journey Context:
Distributed systems principles apply to multi-agent systems. Concurrent writes to the same artifact corrupt state. Developers often assume LLMs will coordinate via context, but they lack real-time awareness of each other's actions. Exclusive locks or centralized state reducers \(e.g., an annotation reducer that appends rather than overwrites\) prevent data loss and ensure consistency.
