Features

1. Student Report Card — Printable progress report with FLN levels, assessment history, skill proficiency, certification status, and teacher/principal/parent signature lines.
2. 404 Page — Friendly fallback for unknown routes and panels.
3. Forgot Password — Secure modal (replaces the old /api/reset endpoint that wiped the entire database).
4. Global Student Search — / shortcut to search students by name, ID, or class. Click navigates to student profile.
5. Error Boundary — Catches panel crashes and shows recovery UI instead of blank screen.
6. Health Endpoint — GET /api/health for uptime monitoring.
7. Session Timeout — 30-minute idle timeout with 5-minute warning modal and auto-logout.
8. Keyboard Shortcuts + System Health Dashboard — ? for shortcuts help. Superadmin gets a real-time health/stats panel.

Bug Fixes Applied (2nd commit)

All features have been audited and critical bugs fixed:

CRITICAL

• Forgot Password wiped entire database — the forgot password flow was calling /api/reset which resets ALL data. Fixed to call /api/auth/forgot-password instead (gracefully handles 404 since endpoint does not exist yet)

Security

• XSS in ReportCardView print HTML — all user-supplied data (student name, school name, topics, narrative) is now escaped via escapeHtml() utility before injection into the print window HTML

Logic Bugs

• conceptMastery merge — was only overwriting with 'Strong', ignored ordering. Fixed to use priority-based merge (Strong > Satisfactory > Needs Practice)
• progressPct — could exceed 100% if currentLevel > 59. Now clamped to Math.min(100, ...)
• latestReport — assumed reports[0] was most recent. Now sorts by timestamp descending
• report_card empty students — crashed when students array was empty. Added guard with NotFoundView fallback

Navigation

• ReportCardView back button — was a no-op (onBack={() => {}}). Now navigates to student_profile panel
• NotFoundView — window.history.back() could leave the app. Now uses onNavigateHome callback
• NotFoundView wired as panel fallback — unknown panels now show 404 instead of blank

UX/Accessibility

• Login demo accounts — used non-existent emails (gps-mt-001.t01@fln.org). Now uses real seeded DB emails
• Forgot password modal — added
  ole=dialog, �ria-modal, Escape key handler, �ria-label on close button
• Demo buttons — disabled during loading to prevent double-submission
• Save as PDF button — relabeled to 'Print / Save as PDF' (no PDF generation exists)

Verified

• sc --noEmit passes with 0 errors
• All 7 demo accounts login successfully through frontend proxy
• 86,400 students confirmed preserved after forgot password call
