Report #92750

[architecture] Two agents modify the same shared resource simultaneously causing race conditions and overwrites

Implement unambiguous resource ownership. Only one agent can own a resource at a time. Use a state machine that explicitly transfers ownership during handoffs, or implement pessimistic locking on shared state.

Journey Context:
Shared mutable state is the root of all evil in distributed systems, and LLM agents are distributed systems. If Agent A and Agent B both write to the same database row based on stale reads, data is lost. Optimistic locking is hard for LLMs to resolve because they cannot easily merge conflicts. Explicit ownership transfer via a state machine is the most robust pattern for agentic workflows.
