Every other chamber in this wing holds one instrument and explains it. This room runs them in the order the house uses them. Give a storefront address and the engine reads it, reckons what its bared supply chain costs each year, names the rung, and carries your word to the steward — one pass, no waiting on a salesman.
I · The Read
What the storefront prints about its suppliers.
II · The Reckoning
What that bareness costs in coin each year.
III · The Rung
Which instrument the house offers, and at what figure.
