-/** @type {import('jest').Config} */
+/**
+ * Base config for packages that test their COMPILED output. It declares no
+ * `preset` and no `transform`, so the TypeScript under `test/` cannot execute
+ * here — run `yarn tsc` first, and expect suites to run from `dist/test`.
+ *
+ * `testMatch` is deliberately left to each package rather than set here:
+ * several of them keep integration suites next to their unit ones and split the
+ * two with the path argument in their `unit` / `integration` scripts. A pattern
+ * hoisted into this file would apply to packages that have no such argument,
+ * enrolling suites that need live warehouse credentials.
+ *
+ * So a package extending this should declare its own `testMatch` pointing into
+ * `dist/`. Without one, jest's default picks up the untransformable sources
+ * under `test/` and a bare `jest` fails on `import` — the path argument in the
+ * npm script is then the only thing keeping the suite runnable.
+ *
+ * @type {import('jest').Config}
