Costs are from the current-build item data. Research at a Research Table with a found item, or unlock directly through the workbench tech tree with scrap. Full path is the total scrap to reach that node from an untouched tree, prerequisites included — the number you actually pay. A dash means the game files don't carry that figure for the item.
