the.com/quartermaster

The person who knows where everything is, because they ordered it and will never let you forget it.

means A military or naval officer responsible for distributing supplies, equipment, and housing — the logistics keeper who tracks what exists and who gets it.

from From 'quarter' (as in lodgings or billets, from Latin quartus, fourth — originally the quarter of a town or camp assigned for shelter) plus 'master.' The role grew out of the job of assigning soldiers their quarters, then expanded to cover rationing and supplying everything else an army needs — so the word kept the name of housing duty long after the job became about stockpiles and ledgers.
