Report #93686
[architecture] Multiple agents reading and writing to the same shared state dictionary simultaneously cause race conditions and lost updates
Implement an append-only event log \(Event Sourcing\) or pass immutable state snapshots to agents rather than mutable references.
Journey Context:
Passing a mutable dict to parallel agents means Agent B overwrites Agent A's changes. Event sourcing allows the orchestrator to reconstruct state deterministically from the log of actions, preventing write conflicts. The tradeoff is increased memory and complexity in state reconstruction, but it guarantees consistency across concurrent agent operations.
