Report #63998

[architecture] Concurrent agents overwrite each other's state in shared memory causing race conditions

Implement state as an append-only event log \(Event Sourcing\) or use optimistic concurrency control \(e.g., ETags/version numbers\) when agents read/write to a shared state store.

Journey Context:
Multi-agent systems often share a global context dictionary. If Agent A and Agent B run in parallel and update the same key, last-write-wins destroys data. Standard database concurrency patterns \(event sourcing, OCC\) solve this, but developers often use simple dicts, leading to silent data loss in parallelized workflows.
