/**
 * Conformance kit for `StateStore` implementations. D8.
 *
 * The in-memory store is the reference, but anyone writing a Redis, SQL, or KV
 * store has to reproduce behavior that is easy to get subtly wrong: and a store
 * that is subtly wrong produces a guard that is subtly wrong, silently, in
 * production.
 *
 * Shipping the contract as runnable assertions rather than prose means an
 * implementer can prove their store is usable instead of hoping. Framework-free
 * on purpose: it reports failures and lets the caller decide how to surface them,
 * so it works under `node:test`, a browser, or a bare script.
