 guidance must still point operators to the canonical repo-root `npm run dev`

 the primary habit.
+That operator-guidance rule also applies to the managed launcher's recovery and

 That same dev-runtime helper boundary also includes the auxiliary operator
 controls that start, stop, restart, or recover local development. The repo-root
 Makefile targets, `scripts/toggle-mock.sh`, and `scripts/clean-mock-alerts.sh` must
