Report #83753

[architecture] Concurrent agents overwriting each other's state updates due to ambiguous resource ownership

Assign unambiguous, exclusive write ownership for every state key to exactly one agent. For shared read state, use append-only event logs or immutable snapshots.

Journey Context:
Distributed state mutation is notoriously hard. If Agent A and Agent B both write to shared\_context\['findings'\], last-write-wins destroys data. Explicit ownership \(Agent A owns key X, Agent B owns key Y\) or append-only lists prevents lost updates. Tradeoff: Requires upfront key-namespace design and restricts ad-hoc state mutation, but guarantees data integrity without complex distributed locking.
