Suggested reviewers: Merge Risk: 🟠 High · up to The exporter default update is localized, but an unresolved TLS failure path can send credentials over plaintext, creating a concrete security risk; the PR should not merge until that behavior is fixed or explicitly accepted. Several documentation inaccuracies also remain for follow-up. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Full details: Description checkExplanation The description explains the version update and documentation change, but it omits the required issue reference, Features / Behaviour Changes, Implementation, and Testing sections. The checklist also indicates that tests were not added or updated. Resolution Add the required template sections. Include the issue reference, behavior impact, implementation details, and testing performed or test results. Clarify the testing checklist item instead of leaving it unchecked with a brief note בלבד; update the checklist after completing the required checks.

958-967: 🔒 Security & Privacy | 🟠 Major | ⚡ Quick winDo not fall back to plaintext when the cluster requests TLS.
The cluster declares TLS through
cluster.GetTLS(). WhengetTLSConfigfails, this code logs the error and leavestlsConfignil. Line 968 then passesusernameandpasswordtovalkey.GetClusterStateover an unencrypted connection. If the nodes still expose a plaintext port, the operator password crosses the network in the clear.A transient secret read failure, a rotated secret with a bad
ca.crt, or an RBAC change is enough to trigger this path. Keep the scrape failing loudly instead of silently downgrading the transport.🔒 Proposed fix: skip the scrape instead of downgrading

330-330: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick winRemove the contradictory “silently skews” wording.
The paragraph says repeated zones silently skew placement, but it also says duplicate entries are rejected at admission. Say that duplicates would skew the round-robin, or state that admission validation prevents this input.
