[architecture] Multiple agents modifying the same file or database record simultaneously causing race conditions

Implement the Single Writer Principle: assign a single 'owner' agent per resource, or use a central state manager where agents emit state change requests rather than applying them directly.

Journey Context:
Agents operating concurrently will step on each other's toes if they share mutable state. Standard thread-safe concurrency is hard for LLMs because they cannot easily do atomic compare-and-swap. The simplest architectural fix is to partition the state space so only one agent ever writes to a specific resource \(e.g., Agent A owns auth/, Agent B owns db/\). If shared state is unavoidable, agents must request a central state manager to apply diffs.
