public/sitemap.xml:10
- The sitemap.xml only includes the homepage, but the PR description claims "Expand sitemap.xml to include all 8 application routes" and the documentation in DOCUMENTATION.md describes 8 routes being included (homepage, dashboard, internships, hackathons, status-board, calendar, analytics, reports). The actual sitemap is missing 7 routes.
Additionally, since all routes except the homepage require authentication (as noted in the comment), including authenticated routes in the sitemap would expose them to search engines when they should likely have noindex meta tags. Consider either:
- Only including the public homepage in the sitemap (current implementation is correct)
- OR removing the noindex flags from authenticated pages and including them in the sitemap
The current implementation is inconsistent with the PR description and documentation.

- The PR description and documentation claim that the sitemap was expanded to include all 8 routes (dashboard, internships, hackathons, status-board, calendar, analytics, reports, etc.), but the actual sitemap.xml file only contains the homepage. This is a significant discrepancy between what was claimed and what was implemented. However, this may actually be correct from an SEO perspective - since all routes except the homepage require authentication (as noted in the comment on line 3), including them in the sitemap would allow search engines to crawl pages that users cannot access without logging in. The comment "Only public page, all others require authentication" suggests this was an intentional decision. The documentation in DOCUMENTATION.md should be updated to reflect this decision and explain why authenticated routes were not included in the sitemap.

The comment states that react-helmet-async@2.0.5 doesn't officially support React 19 yet, and legacy-peer-deps is required. While this is a pragmatic solution, there's a risk that the library may have incompatibilities with React 19 that haven't been discovered yet. Consider: 1) Testing thoroughly to ensure no runtime issues, 2) Adding a TODO or tracking issue to monitor for React 19 support, or 3) Evaluating if there's an alternative library with official React 19 support. The "Last verified: 2026-01-18" date is helpful for tracking.

| # NOTE: Do not enable global legacy-peer-deps here to avoid silently | |
| # installing packages with unsupported or mismatched peer dependencies. | |
| # If installation fails due to the react-helmet-async peer dependency | |
| # while React 19 is still in use and verified in this project, run: | |
| # npm install --legacy-peer-deps | |
| # or append --legacy-peer-deps to specific install commands as needed. |
