List HarnessBuilds

Returns a cursor page of the Organization’s HarnessBuilds. Each records its explicit platform or Workspace/RunnerPool execution target, repository, frozen commit, executable contract, status, attempt count, and successful HarnessRelease. Builds are append-only history: a terminal build never changes, and re-registration appears as a new build.

Checkfu support posture: alpha; hosted. Required evidence journey: harness-registry. Deployment-specific readiness and the latest proven release are available from GET /v1/support/capabilities.
