+// references.
+//
+// # Where the answer comes from, and where it must NOT come from
+//
+// The obvious source is the materialised award_refs column: it is already on
+// every row and one query reads it. It is also the wrong answer twice over.
+// That column holds DISPLAY LABELS, not references — depending on the award's
+// RefDisplay it can read "Krasnogvardeysky" or "ST-25 — Krasnogvardeysky", and
+// DXCC stores a country name — and it is a derived cache that lags: a QSO whose
+// references were back-filled (see BackfillRDA) counts on the Awards grid long
+// before anything recomputes its column. The first build of this badge used it
+// and marked a district worked on five bands as NEW.
+//
+// So the answer comes from the same place the Awards grid's answer comes from:
+// award.MatchQSO over the logbook. What is engineered here is the COST of that,
+// because the question is asked while the operator is logging:
+//
+//   - the set is per award CODE, and built only for codes actually asked about;
+//   - it reuses the award snapshot when one is already in memory, which it
+//     usually is (the Awards tab, the cluster status index);
+//   - otherwise it STREAMS the logbook rather than materialising a second copy
+//     of it — the references of one award are a few thousand short strings;
+//   - and it is built in the BACKGROUND. A caller that asks before the set is
+//     ready is told so and gets no badge, never a wait and never a wrong badge.
+//
+// A freshly logged QSO's references are folded into the sets, so a normal
