+ * Sibling/mirror windows used to compute a placement's tie span from the players
+ * present on THAT window's roster (a subset of the field), so a tied group split
+ * fewer ways and over-awarded — tennis Round-of-16 losers landed at 2 QP instead of
+ * the correct 1.5 (positions 9–16: (2+2+2+2+1+1+1+1)/8). processQualifyingEvent now
+ * derives the tie span from the canonical full field, so re-running the fan-out
+ * rewrites the stored event_results QP, participant totals, and league standings.
+ *
+ * This is idempotent and SILENT: notifications are suppressed so re-scoring history
+ * (2 → 1.5 for many participants) does not re-ping every league's Discord. It does
+ * NOT re-link events or designate primaries — run backfill-major-linking.ts first if
+ * the data predates the shared-major model. majorsCompleted needs no fix (it is now
+ * derived on read from completed qualifying events).
+ *
