+### Redirect System
+
+`previous-docs-redirects.js` contains redirects for renamed/moved pages. Entries are organized in sections with comment headers for maintainability.
+
+**Tests:** Run `bun run test` to validate redirects:
+- Required fields (`source`, `destination`, `permanent: true`) are validated
+- No duplicate source paths
+- Source paths must start with `/docs/` (except `/auto-top-ups` for top-level redirects)
+- Section headers are required for organization
+
+**Adding redirects:** Place new redirects in the appropriate section or add a new section header. All redirects must use `basePath: false` to work correctly under the `/docs` base path.
