Migrate Healthcheck Payload

This page targets @nexload-sdk/healthcheck-payload 2.1.0 with Core 4.1.0. Identify your source version in the Payload integration changelog.

Upgrade core and Payload integration together, while keeping the installed Payload major within the declared peer range.

Type-check the collection and where values; test successful, empty, minimum-not-met, thrown-query, and timeout paths. Confirm the check remains readiness-only and that protected diagnostics are the only place where causes appear.
