  * ## Why the whole family, from one expectation
  *
- * The contract has one implementation face per command, and there are ten of
- * them. A file that pinned `migrate recorded-by` alone would go green while the
- * other nine stayed broken, and would say nothing at all about the eleventh. So
- * the family is DISCOVERED from the source tree — every command that calls
- * `bootSchemaStack` and declares a `--json` flag — and the discovered set is
- * reconciled against {@link FAMILY} below. Add a member and this file goes red
- * until it is listed here and passes; drop one and it goes red until it is
- * removed. The seam itself (`bootSchemaStack`'s required `jsonOutput` option)
- * makes the mistake a compile error first; this is the runtime proof that the
- * seam actually delivers the invariant.
