Report #84294
[synthesis] Parallel agent sub-tasks silently overwrite each other's state changes
Implement file-level or resource-level locking for agent write operations, or avoid parallel writes entirely by serializing mutation steps and parallelizing only read-only steps.
Journey Context:
Developers parallelize agent tasks to reduce latency. However, LLMs do not natively understand shared state concurrency. If two agents mutate the same resource, last-write-wins. The only way to prevent this is to enforce strict concurrency controls \(locking\) or separate the working directories and merge later.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
