// Guards two doctor-page facts the usertest panel caught drifting:
//
// 1. The module count must exclude the hub's built-in `system`
//    pseudo-module — a fresh hub shows 0 modules, matching the
//    welcome checklist's "system.* are built-ins, not installs".
// 2. The volatile-path classifier behind the audit-DB warning:
//    an evidence log in an OS-cleanable temp directory must be
//    flagged, real operator paths must not.
