Report #59419

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

Implement the Single-Writer Principle / unambiguous resource ownership. Only one agent owns a resource at a time; others must request mutation via messaging to the owner.

Journey Context:
Developers often use shared databases or global state objects accessible by all agents, forgetting distributed systems 101. Tradeoff: message passing adds latency compared to direct mutation, but prevents race conditions. Alternative: distributed locks, but locks are extremely brittle in LLM contexts due to non-deterministic execution times and high risk of deadlocks if an agent fails mid-task.
