What's Changed

Themes & Accessibility

• New responsive rules for narrow screens (hides prev/next buttons and XP badge, breadcrumb truncation)

My Notes

Fixes & Quality

• Lab completion now correctly awards the bonus XP it advertises (steps × 15 + 40)
• Fixed a desktop crash when answering quiz questions in the packaged app
• Corrected two quiz answer keys (OS hardening, legal scope of testing) and clarified the WPS PIN explanation

Unified XP System

My Progress Page

• Rank system: RECRUIT → LEARNER → ANALYST → DEFENDER → WHITE HAT → SPECIALIST → RED TEAMER → CYBER GUARDIAN

• Track breakdown across all 6 learning tracks
• Mission lab progress with locks, full module checklist, and "Next up" suggestion

Lab Center
