[architecture] Parallel identical agents attempt the same non-idempotent action, causing duplicate writes

Partition the task space before spawning parallel agents \(Map-Reduce style\) or assign unique, non-overlapping scopes combined with idempotency keys for shared resources.

Journey Context:
Parallelizing LLM work seems like a great way to speed up execution. However, without partitioning, agents act like threads with shared mutable state and no mutex. They read the same initial state, decide to do the same work, and clash on write. Map-Reduce or strict scope assignment prevents collisions. The tradeoff is the overhead of the partitioning step, but it prevents catastrophic duplicate side effects \(like double-charging a user or writing duplicate files\).
