Term	Kind	Topic	What it is

Consumer-Driven Contract CDC, Pact Testing	pattern	Consumer-Driven Contracts	A machine-checkable expectation written by the consumer of an API and verified against the provider's build, catching integration breaks without a shared environment.
Contract Coverage Gap Contract Blind Spot, Unasserted Field Surface	metric	Consumer-Driven Contracts	The share of a provider's response that a consumer's code reads but its contract never asserts on - the exact surface a provider can delete while every contract check stays green.
