[architecture] Race conditions and overwrites when multiple agents mutate the same file or artifact

Assign unambiguous, exclusive ownership of every mutable resource \(file, database record, state key\) to exactly one agent at a time.

Journey Context:
In distributed AI systems, giving multiple agents write access to the same artifact inevitably leads to the 'lost update' problem—Agent A overwrites Agent B's changes because it read the file before B finished writing. Alternatives like LLM-based 3-way merging are notoriously unreliable and hallucination-prone. File locking introduces deadlock risks if an agent fails mid-task. Exclusive ownership \(e.g., the Architect agent owns the system design until explicitly handed off\) guarantees consistency at the cost of sequential bottlenecks, which is a necessary tradeoff for correctness.
