+ * Stress + Strain nightly score jobs and the dense intra-day retention
+ * drain.
+ *
+ * Same source-text-grep approach as the WX-C recovery-score guard: assert
+ * each queue is imported, registered in `allQueues`, scheduled (the two
+ * cron-driven score jobs), and wired to a `boss.work` handler — without
+ * booting pg-boss + Prisma. An unregistered queue silently never drains
+ * (the recurring past bug this guards against).
