+/**
+ * Release completeness (D24) for fewer releases, and without binaries
+ * (LOG.md 2026-10-07 (7)).
+ *
+ * - Only releases whose completeness can change are noted for the sweep: a
+ *   par2 listing, a file_total, or complete now (it can become incomplete).
+ *   For any other release release_complete() is false by definition; noting
+ *   every release a file went into made a sweep check 430,000 releases in
+ *   51 minutes.
+ * - release_complete() matches listed files by name against the files
+ *   themselves (coalesce(real_name, filename)); the size match still goes
+ *   through a binary when there is one. Seeding no longer creates binaries
+ *   for most files and the GC deletes them, so a name only reachable through
+ *   a binary was lost.
+ * - Notes that don't qualify are dropped.
