Merge Risk: 🟠 High · up to The SSH-based liveness change can treat an invalid endpoint as unreachable without probing, potentially tainting live nodes and detaching volumes, while non-positive retries can report nodes as reachable without any probe. These health-state errors create a high-impact availability risk, so the PR is not merge-ready until the probing and input-handling behavior is corrected. 🚥 Pre-merge checks | ✅ 2 | ❌ 3❌ Failed checks (3 warnings)

193-204: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueThe fatal branch is now unreachable, and its comment is stale.
SSHPingwraps every failure withErrUnreachable, andpingAlljoins only errors returned bySSHPing. Soerrors.Is(err, clusters.ErrUnreachable)is true wheneverPingLoadBalancerNodesreturns a non-nil error. Thereturn result, errpath at line 200 cannot be taken today. The comment at lines 198 and 199 still cites raw-socket permission problems, which no longer apply after the ICMP removal.Keep the branch as defensive code if you prefer, but update the comment to describe the SSH failure modes.

Inline comments:
In `@internal/clusters/ping4.go`:
- Around line 96-107: Update SSHPing to handle non-positive retries before
entering the retry loop, returning a non-nil error instead of reporting success
without performing a probe; preserve the existing retry behavior for positive
retry counts.
- Around line 127-139: Update the endpoint credential handling in the node-ping
flow around SSHPing and UnknownLoadBalancersNodes so empty static
NodeKeys[n.Public] or dynamic PrivateKey values are classified separately from
unreachable nodes. Preserve the existing unreachable-node behavior, but route
missing SSH credentials through the reconciliation path that can repair or
replace the node instead of causing Workflow_ERROR.
In `@internal/nodepools/nodepools.go`:
- Around line 43-44: Correct the grammar in the NodeSSHUsername documentation
comment so it states that the username defaults to “root” when it is not set.
In `@services/kuber/internal/worker/service/task_delete_nodes.go`:
- Around line 258-269: Update deleteUntrackedNodes and the Deleter.DeleteNodes
flow so drifted nodes with a zero clusters.NodeEndpoint are not tainted
out-of-service without a real reachability or power-state check. Perform and
honor an actual probe before applying the node.kubernetes.io/out-of-service
taint, while preserving deletion handling for confirmed-unreachable nodes.
In `@services/manager/internal/service/healthcheck.go`:
- Line 52: Update the doc comment for the UnreachableIPv4Map type so it begins
with the exact declared symbol name, while preserving the existing description.

Closes #2181
Changes in this Pull Requests drops all previous usage of raw ICMP packets for pinging (only used for LoadBalancer nodes) and replaces them with SSH pings that timed-out after ~4 seconds if the node is unreachable.
