On 2026-08-16 a relaunch happened before the previous process exited. Two makers ran against one account, each posted its own orders, and every leg ended up with two resting. The duplicate guard could not recover: it cancels BOTH orders on a leg and the other process re-posted immediately, so resting orders climbed 54 -> 81 while the guard fired continuously. Every other safety in mm_maker_live assumes a single writer -- the duplicate guard, the resting-over-cap abort, the post budget, the ratchet floors held in state. This test holds the assumption that makes them valid. No network, no orders.
