Report #10729

[architecture] Concurrent file or state mutations by multiple agents cause race conditions and overwrites

Assign unambiguous, exclusive resource ownership to a single agent for the duration of a task, implementing a single-writer principle.

Journey Context:
Optimistic locking or concurrent writes work poorly in LLM loops because agent execution is slow and non-atomic; by the time an agent finishes writing, the context it based the write on is stale. Pessimistic locking \(Agent A exclusively owns File X\) prevents merge conflicts at the cost of reduced parallelism, which is the correct tradeoff for code generation.
