/**
 * `parent="Name"` and `parent="Name.Value"` — what a child may be built over.
 *
 * A parent selects rows by the VALUE it produced: `parent="Gender.Male"` is
 * "the rows where Gender came out Male". Two things follow, and both used to be
 * found only when the run was already underway.
 *
 * The parent has to exist by the time the child is declared, because the rows it
 * selects are what the child is built over — and it has to have a value at all.
 * A compound sequence is a group of fields and produces none, so no row could
 * ever match it; the engine discovered that mid-generation and reported the
 * parent as "unknown", sending the reader to look for a name declared right
 * above.
