Report #21476

[architecture] Multiple agents mutating the same file or state artifact simultaneously causing race conditions and overwritten work

Implement unambiguous resource ownership where exactly one agent \(or a mutex-locked tool\) has write access to a specific file or state key at any given time.

Journey Context:
Distributed systems principles apply to multi-agent systems. If Agent A and Agent B both write to main.py concurrently, they will overwrite each other's changes. You must partition the workspace \(e.g., Agent A owns backend, Agent B owns frontend\) or use a centralized locking tool. Tradeoff: requires upfront partitioning and limits cross-cutting changes, but guarantees no write conflicts.
