Summary

Links such as /api/3.0.0/ currently return 404. Add permanent redirects from /api/<version> and /api/<version>/ to the existing /<version>/api page for every registered documentation version, including snapshot and older releases.

Generate the aliases from the version registry so the app's other /api/ endpoints keep their routes. Preserve query strings.

Validation

• Passed bash scripts/test-docs-release-links-contract.sh.
• Passed npm run build in docs-app with locked Next.js 16.3.6, including TypeScript checks.
• Checked the production server: both alias forms return HTTP 308 for all 8 registered versions; the alias and canonical 3.0.0 URLs resolve to HTTP 200; query strings are preserved; an unregistered API path stays 404.
• Checked the production redirect manifest: /api/ redirects cover only registered versions.
• npx eslint next.config.ts could not start because the repository's TypeScript 7 dependency is unsupported by typescript-eslint. Dependency files are unchanged.

To verify locally from the repository root:

npm ci --prefix docs-app
npm run build
npm start -- --port 3137

Open http://localhost:3137/api/3.0.0/ and http://localhost:3137/api/3.0.0. Both should redirect to /3.0.0/api and show the API documentation page. Repeat with /api/snapshot/ and an older registered version. A query such as ?search=LineChart should survive the redirect.
