A bank, insurer, carrier, or hospital integration desk has more than one partner API. The gate is the registry of those contracts.
Contract Gate — after the first delivery
The next recording has to match.
mimicplus turns one allowed recording into the client. Contract Gate keeps that spec as the last approved contract. A later HAR fails the build when a field is removed or renamed. One named approval can waive that break. It cannot hide the others.
It runs mimicplus diff. It does not invent a second opinion. The acme proof still fails on four breaks.
The $199 key buys the delivery. The monthly gate is planned. There is no second checkout on this page.
