Report #77876

[synthesis] Two parallel agents modify the same file, causing interleaved corruptions that each agent individually validates as correct but collectively breaks the system

Implement file-level or resource-level locking, or assign strictly partitioned namespaces \(directories, tables\) to each agent, merging only at the end.

Journey Context:
Concurrency control is well-understood in databases, but agent frameworks often treat the file system as a shared, unlocked sandbox. The synthesis reveals that parallel agents suffer from the 'lost update' problem. If Agent A and Agent B both read, modify, and write config.yaml, one will overwrite the other's changes. Each agent sees its own change and thinks it succeeded. The compounding error is the silent data loss of the other agent's work. Enforcing partitioned namespaces or locking prevents interleaved mutations.
