Held until you confirm receipt.
Escrow holds your payment until you confirm receipt, so a vendor cannot take the money and fail to deliver. Osiris runs standard 2 of 3 multisig.
You fund the order into escrow, the vendor ships, you confirm receipt after the package arrives, and the coin releases. If something goes wrong you open a dispute instead of confirming.
The protection disappears the moment you confirm, so never confirm before the package is in your hands. Confirming early, finalising early, is the single most common way a buyer throws away escrow. Osiris locks it until a vendor has earned it.
