What you import

name
`sampleInput`
`Cases`
`testApp`	An app to ask questions of, wired the conventional way.
`checkContract`	The declared contract, posed to the façade that will receive it.
`checkOutput`	What may leave, checked against what the entity says may leave.
`verdictOf`	What a facade answers, in the shape a verdict is compared in.
`stubOf`	A double for a port.
`frondOf`	The frond a path sits in, or nothing.
`loadScript`	A k6 scenario, written from what the app answers.
`reachableOps`	Every operation the app answers, with a body for those that take one.
`statementsOf`	Every statement the process ran while `run` ran; refuses when `@fougere/adapter-sql` is absent.
`spansOf`	The steps one call opened: the operation, then what ran under it. Ex: `expect(op.selfMs).toBeLessThan(0.1 * op.ms)`.
`checkDoorContract`	Run one hand-written invocation contract through every facade.
`checkDoors`	One entity, four facades, the same answers.
`at`	Follow a path into a GraphQL answer, tolerating an absence rather than throwing.
`driftOf`
`agrees`
`explain`
`checkAll`	The whole suite, for every entity, from a file that names none of them.

TypeScript types only — they do not run. Import them with import type to type your own code: a variable, a parameter, an option object.

name
`ValidationCase`
`Verdict`
`Port`	Anything a provider can be declared as: a class the container knows how to build.
`Stub`	The double handed in place of a port — one spy per method the port declares.
`Scope`	What a test file's position states about its subject.
`CardDrift`
