Report #12462

[architecture] Race conditions and corrupted state when multiple agents write to the same shared resource simultaneously

Assign unambiguous single-writer ownership to shared resources \(e.g., Agent A owns the database, Agent B owns the filesystem\) or implement a transactional state graph with reducers.

Journey Context:
In multi-agent setups, naive shared state leads to race conditions where Agent A overwrites Agent B's changes. While locking mechanisms exist, the simplest architectural fix is the single-writer principle—only one agent mutates a specific domain. If shared mutation is strictly necessary, use a state graph with deterministic reducers \(e.g., appending to a list rather than overwriting\) to resolve conflicts.
