Report #84316

[architecture] Concurrent agents mutating shared memory cause race conditions and lost updates

Replace shared mutable state with an immutable, append-only event log \(Event Sourcing\) where agents read the history and propose new events, rather than overwriting a shared JSON object.

Journey Context:
Developers often give agents access to a shared state dictionary. If Agent A and Agent B run concurrently and update the same key, last-write-wins, causing data loss. Traditional locking is too complex for LLMs. Event sourcing solves this: agents emit immutable Event objects \(e.g., UpdateNameEvent\). The state is derived by replaying the log. This guarantees auditability and eliminates race conditions in multi-agent workflows.
