 * already consumes in production). vitest-free BY CONTRACT: the kits run under any harness — a
 * vitest binding passes `(name, fn) => { it(name, fn); }`, a bare script passes nothing and gets
 * the sequential default — so a third-party store implementor needs NO test framework to verify
 * their backend (shell/client-core run self-written runners).

 * ⚠️ Binding note (inherited from workflowRunStoreContract): cases are REGISTERED
 * eagerly — an async runner that starts work immediately will interleave cases. Every case builds
 * its own fresh store via `make()`, so interleaving is safe UNLESS your binding's stores share
 * state (e.g. SQL twins on one table); such bindings must serialize inside `runAssertion`.
