Ote Binary Stdout Contract	✅ Passed	Dependency upgrade only, no code changes. Not an OTE binary; check not applicable.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	No new Ginkgo e2e tests added. PR only updates go.mod dependency versions for CVE-2026-33186. Custom check only applies when new Ginkgo tests are introduced.
