A BCH-priced offer is a signed transaction with a fixed amount, so a seller who wants "$500" had to relist whenever the rate moved. The new USD mode moves the certificate into a small CashScript covenant (contracts/usd-listing.cash). Anyone may buy it by paying the seller target_cents / price, where the price comes from a message signed by the gateway's oracle key — the median of five exchanges the site already uses. The payout is clamped to a floor/ceiling band the seller sets, and the seller can reclaim the certificate at any time. What the chain can and cannot enforce, stated plainly in the contract and the UI: script can require a transaction to be mined no earlier than a time, never no later, so a quote cannot expire on-chain. The band is the guarantee, and quotes are bound to the listing's outpoint so cancelling and relisting voids every quote ever issued. An offline libauth VM test covers list, buy, underpayment, foreign-listing quotes, forged quotes, band clamping, cancel and a non-seller cancel; on chipnet aloevera.test was listed at $0.30, bought by a second wallet for 119,090 sat at $251.91, listed again by the new owner and cancelled. Gateway: GET /api/price/oracle[?txid=] serves the oracle public key and per-listing signed quotes; the key lives in oracle.key beside the gateway, never in the repo. POST /api/market accepts kind "usd" after reproducing the redeem script from the stated terms and finding the certificate in that covenant; such listings are pruned once the covenant output is spent; DELETE accepts the listing's seller while the index shows the covenant as holder. Dashboard: the Sell tab has "Price is fixed in: US dollars / BCH", a band control with the resulting BCH range, and cancel through the covenant. Market: USD listings show the dollar price, today's BCH equivalent and the band; buying fetches a quote and completes the covenant spend. Studio no longer sends a needless UPD when the registry view is stale, and missing files on a name now get a real 404 page.
