Report #41318

[architecture] Race conditions and corrupted state when multiple agents read/write simultaneously

Assign unambiguous, exclusive ownership of state resources to a single agent at any given time, or use transactional state reducers that define deterministic merge logic for concurrent updates.

Journey Context:
Giving all agents read/write access to a global context dictionary seems like an easy way to share knowledge. But concurrent writes lead to lost updates \(Agent A overwrites Agent B's work\). The fix is to partition state by owner or route all mutations through a single authoritative 'State Agent' or transactional store with reducers, mirroring the Shared Database Anti-Pattern in microservices.
