Migrate Healthcheck Next.js

This page targets @nexload-sdk/healthcheck-next 2.1.0 with Core 4.1.0. Identify your source version in the Next.js changelog.

Upgrade core and Next integration together. Type-check route factories and verify GET/HEAD, status mapping, content types, no-store headers, summary/JSON formats, metrics formats, custom headers, and unauthorized responses.

Test protection behind the real proxy before deployment. Preserve route paths used by probes and scrapers. Roll back if status or authentication behavior changes unexpectedly.
