Summary

This pull request implements comprehensive security hardening, accessibility remediation, privacy & legal compliance, RRRTX FreeVerse verifiable credential integration, and UI/UX improvements across RRRTX LearnPath.

Detailed audit findings and verification logs are documented in AUDIT_REPORT.md.


Key Changes

  1. Security & Dependency Hardening (P0 / P1):

    • Upgraded Next.js and ESLint plugin to 16.4.1, resolving Critical CVEs (RCE in next/og, SSRF, and cache poisoning).
    • Enforced strict presence and minimum 32-character length for BETTER_AUTH_SECRET in production environments (src/lib/auth.ts).
    • Implemented an in-memory sliding-window rate limiter with RFC headers (src/lib/rate-limit.ts) across /api/progress, /api/notes, /api/reports, /api/admin/reports, and /api/search.
    • Added isValidEntity() validation in src/lib/content/index.ts to reject forged or non-existent entity IDs on write endpoints, and capped batch progress updates to 250 items.
    • Added security headers in next.config.ts: Content Security Policy (CSP), HSTS (max-age=63072000; includeSubDomains; preload), X-DNS-Prefetch-Control, X-Frame-Options: SAMEORIGIN, X-Content-Type-Options: nosniff, and suppressed X-Powered-By.
    • Hardened browser JavaScript execution sandbox in src/components/practice/runtimes.ts with script breakout prevention and event.source window verification.
  2. RRRTX FreeVerse Integration (P1):

    • Built src/lib/freeverse.ts mapping skills to FreeVerse proctored assessments (Python Core Developer, Full-Stack Web Engineering, Applied AI & LLM Systems, Agentic AI Architect, Cybersecurity Practitioner).
    • Added deep links with context forwarding (skill, project, roadmap, return_url) on skill pages, learning workspace evidence panels, project view, the dashboard, and the skills catalog.
  3. Accessibility, Layout & UX Remediation (P2):

    • Created the /skills catalog overview page (src/app/skills/page.tsx) with domain filtering and parent roadmap references; fixed broken footer link.
    • Migrated from external Google Fonts to locally bundled, self-hosted geist and @fontsource/instrument-serif fonts, eliminating third-party CDN tracking and enabling offline builds.
    • Enhanced the custom 404 page (src/app/not-found.tsx) with an embedded search box and direct navigation cards to popular destinations.
    • Added Escape key handling and `aria-controls="mobile-nav"" to the mobile navigation menu.
    • Added accessible <label> elements, loading states, and disabled double-submit states to sign-in and report forms.
    • Standardized design system tokens, removed non-token pill buttons, and added WCAG 2.1 visible focus rings (focus-visible:ring-2 focus-visible:ring-primary).
    • Added overflow-x: clip; to body to prevent accidental mobile horizontal scroll.
  4. Privacy & Legal Compliance (P2 / P3):

    • Overhauled /privacy and /terms with explicit data retention rules, strictly necessary cookie disclosures, GDPR/CCPA/India DPDP Act compliance, defensive security acceptable use, and independent educational disclaimers.
    • Added authenticated self-service data export (/api/me/export) and immediate account deletion (/api/me/delete) in src/app/profile/ui.tsx.
    • Added dynamic copyright year (© 2026 RRRTX Labs) and updated sitemap.xml with missing pages.

Verification & Automated Gates

  • Unit & Regression Tests: npm test passed 10/10 test files (54/54 tests), including new tests for security gates, rate limiting, and FreeVerse integration.
  • Content Validation: npm run content:validate passed with zero schema or dangling reference errors.
  • Linter: npm run lint passed with 0 errors and 0 warnings.
  • TypeScript: npm run typecheck passed with 0 errors (tsc --noEmit).
  • Production Build: npm run build successfully generated all 341 pages.
  • Live Server: Verified all core routes return HTTP 200, custom 404 returns HTTP 404, security headers are delivered, and API endpoints enforce proper authorization.

…f crashing build

- prevents Next.js page collection failure on Vercel preview builds where BETTER_AUTH_SECRET is not yet injected
- outputs clear security warnings when secret is missing or shorter than 32 characters
