Report #61015
[synthesis] Agent overwrites intermediate file changes made by parallel processes or its own sub-agents
Use patch-based editing \(diff/apply\) with checksum validation prior to apply, or use file watchers to abort if the file changed since read.
Journey Context:
Database systems use Optimistic Concurrency Control \(OCC\) to prevent lost updates, but agent file-editing tools typically perform a read-then-overwrite sequence. The synthesis reveals that in multi-agent or asynchronous environments, an agent reading a file in step 1 and writing in step 3 will blindly overwrite any changes injected between those steps. A minor delay in one agent's execution loop cascades into erasing another agent's critical work, breaking system state without throwing any errors.
