Efficiency index: 14. This is a route-planning comparison, not a promised completion time.Route workflow
Turn a messy server into three jobs.
Separate categories.
Sorters split Studio, Horror, Anime, Trading, and other themes so shelvers do not need to inspect every pile.
Preserve row order.
Shelvers stay near assigned rows, place the right category, and pause to audit when a row looks complete but stays inactive.
