Report #65917

[architecture] Multiple agents reading and writing to shared state concurrently cause race conditions and lost updates

Implement an append-only event store or use optimistic concurrency control \(e.g., ETags/versioning\) for shared state, rather than allowing agents to arbitrarily mutate a single global dictionary

Journey Context:
Agents acting as independent threads mutating shared state is a classic concurrency anti-pattern. Append-only logs preserve history and allow deterministic replays. Tradeoff: state size grows indefinitely, requiring compaction or summarization agents to maintain a manageable working context.
