Community realm. Read the code first. Community realm, deployed by its author. Read the code before you interact or send coins.
Package market is the platform's immutable fixed-price market (design §2.5.4). It never holds a token: the seller approves this realm in core, the token stays in the seller's wallet, and Buy moves it through core's official grc721 RealmTeller in the same transaction that pays everyone. It never holds coins either (I-3).
Stale listings (RA H-2) cannot be bought: a listing pins the token's move counter at listing time, and Buy requires owner == seller and the counter unchanged (I-8). A listing that went stale never blocks the new owner: List overwrites it and anyone may CancelStale it.
Pause ("trade" in core) stops List and Buy only. Cancel, CancelStale and UpdatePrice are never paused (I-2).
ListingOf is the live listing of a token as JSON, or "null".
