Report #24878

[architecture] Multiple agents writing to the same file or resource simultaneously causes race conditions and silent overwrites

Implement strict, unambiguous resource ownership where only one agent can mutate a specific file or state key at a time, requiring explicit handoff or lease acquisition.

Journey Context:
Multi-agent systems often fail silently when agents overwrite each other's code. Optimistic locking fails in LLM flows because generation is slow and expensive to retry. Pessimistic locking \(ownership\) is better. If Agent A owns auth.py, Agent B must request ownership or emit an event for A to make the change. Tradeoff: limits parallelism, but guarantees consistency.
