+  (`repeated-boot-notification`) by `MayurK-cmd`, their second (PRs #169 and #170).
+  Both arrived within two days of being assigned.
+- ✅ #170 needed its branch repaired before it could land, and the repair is worth

+Rule coverage: **complete**. All 16 detection rules now have a scenario exercising

+registry rather than by reading: 16 of 16 codes appear in some scenario's
+`expectedFailures`.
+
+Scenario corpus: **21**, which clears the 20+ target in the v1.0 milestone
+(`ROADMAP.md` line 157). That exit criterion is met; the remaining v1.0 work is API
+stabilization, the docs overhaul and release hardening.
