145-162: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
ModeSinglenow runs the validator twice, but the outer budget still assumes one run.
cpRCandgpuRCboth setClusterValidatorin theModeSinglebranch, and the twoRunPreflightForRolecalls at Line 482 and Line 483 are sequential. EachrunClusterValidatorinvocation owns a 5-minuteclusterValidatorTimeout, so the worst case is 10 minutes plus RBAC bootstrap and log fetch.outerTimeoutis 6 minutes. The compute-plane validator then derivesvctxfrom the remaining ceiling and its wait is truncated, which is the exact failure the comment at Line 155 sets out to prevent.Two related effects in the same path: the second run calls
sweepPriorClusterValidatorJobs, which deletes the control-plane Job, so--no-cleanupcannot preserve it for debugging.Size the budget for the number of validator runs.

resolveStackValuesFiledepends on the operator's working directory and a fixed environment name.The function walks up from
os.Getwd()fordeploy/stacks/self-managed/environments/local.yaml. Two limits follow:
- An installed CLI run outside the source tree never finds the file, so
global.image.registrynever contributes a registry entry.- The path pins the
localenvironment. An operator running a staging or production environment file gets no registry from this source.Add a flag or Viper key for the values file, and use this walk only as the fallback.

Inline comments:
In `@src/clis/nvcf-cli/cmd/self_hosted_check_test.go`:
- Around line 390-448: Update TestCheck_ComputePlaneFlagRunsChecks and
TestCheck_ControlPlaneFlagRunsChecks to run with --skip-cluster-validation, and
set NVCF_CLI_SELFHOSTED_SKIP_INOTIFY via t.Setenv in each test. Preserve the
existing JSONL parsing and category assertions.
In `@src/clis/nvcf-cli/cmd/self_hosted_check.go`:
- Around line 200-207: Update the registry credential setup block to run
whenever !localOnly, removing the clusterValidatorImage non-empty condition.
Continue obtaining extraRegistries and stackValuesFile, and pass the possibly
empty clusterValidatorImage to selfhosted.EnumerateRegistries so
global.image.registry and configured extras are checked independently of the
validator image.
In `@src/clis/nvcf-cli/internal/selfhosted/clustervalidator.go`:
- Around line 210-225: Confirm the validator’s namespace-wide write requirements
by tracing the operations used by the validator binary, especially namespace,
pod, service, and network-policy checks. If writes only target the probe
namespace, replace the cluster-wide permissions with namespace-scoped
Role/RoleBinding access while retaining required cluster-wide read permissions;
otherwise, add cleanup in the --cleanup flow to delete the validator ClusterRole
and ClusterRoleBinding after the run.
- Around line 145-150: Preserve the error from ensureClusterValidatorConfig in
the control-plane path instead of assigning it to _. Store a non-fatal config
note and append it to cleaned before every ClusterValidatorResult return, or
otherwise expose it through the result transcript, while retaining the wrapped
error context and continuing validation.
In `@src/clis/nvcf-cli/internal/selfhosted/preflight.go`:
- Around line 348-353: Ensure the registry-credentials category is constructed
and executed only once per command invocation, rather than once for each role
passed to RunPreflightForRole. Update buildCategories or the cmd-layer
orchestration around RunPreflightForRole to gate registry handling to a single
role/invocation while preserving all other role-specific categories and result
emission.
- Around line 687-690: Update the stale-namespace message construction around
r.Message to emit remediation hints per stale reason rather than one blanket
kubectl delete command. For “stuck Terminating,” direct operators to remove
namespace finalizers; for “no Helm release,” provide a cautious
inspection/removal hint that does not imply force-deleting the namespace.
Preserve the stale namespace names and counts in the output.
In `@src/clis/nvcf-cli/internal/selfhosted/registry_cred.go`:
- Around line 172-178: The registry endpoint parsing must preserve non-default
ports and correctly handle IPv6 and trailing-colon inputs. In
src/clis/nvcf-cli/internal/selfhosted/registry_cred.go lines 172-178, update the
extras handling around parseRegistryHostPort so RegistryEntry.Registry retains
the parsed port when it is not 443, allowing probeRegistryCredential to use the
correct URL. In src/clis/nvcf-cli/internal/selfhosted/clustervalidator.go lines
386-408, replace the manual parsing in parseRegistryHostPort with
net.SplitHostPort and strconv.Atoi, and add table cases covering [::1]:5000 and
nvcr.io:.
- Around line 95-108: The probeRegistryCredential flow must require configured
credentials for critical registry entries before accepting a successful
exchangeBearerToken result. Check credentialsForRegistry and the entry’s
critical status before returning success, while preserving the existing
rejected-credentials error for configured credentials and the anonymous-token
behavior for non-critical entries.
In `@src/clis/nvcf-cli/internal/selfhosted/stale_namespace.go`:
- Around line 103-111: Update the Secret List call in the stale namespace check
to set ListOptions.Limit to 1, since only existence is required. Add a concise
comment documenting that this check assumes Helm’s default secret storage driver
and may report namespaces using configmap or SQL storage as having no Helm
release.
In `@src/clis/nvcf-cli/internal/selfhosted/validatortag.go`:
- Around line 334-343: Trim whitespace from unquoted parameter values in the
parsing branch of the validator, before assigning or using val. Preserve the
existing comma splitting and empty-params behavior, while ensuring values such
as service after a comma are passed without leading spaces.
- Around line 218-229: Validate the realm URL before applying credentials in the
request flow around credentialsForRegistry: parse the realm and reject it unless
it uses HTTPS and has an acceptable host for the registry authentication
endpoint. Ensure this validation occurs before req.SetBasicAuth, so credentials
are never sent to HTTP or unrelated hosts.

VALIDATOR_ROLE is a dead env var — nothing reads it, so this whole feature inverts into a guaranteed failure on every healthy control plane.
grep -rn VALIDATOR_ROLE outside src/clis/nvcf-cli returns nothing. nvca/cmd/cluster-validator/main.go reads only VALIDATOR_CONFIG_NAMESPACE / _NAME / _PREFLIGHT / _SUMMARY_NAMESPACE and calls clustervalidator.Run(ctx, client, configNS, configName, summaryNS, emitMetrics) — no role argument. The RoleControlPlane / RoleComputePlane constants that preflight.go:268-272 says this "must match" do not exist in that package.
So the Job runs the unchanged GPU-centric check set. validator.go:164-165 unconditionally runs checkGPUResources / checkGPUOperator, and printSummary marks {state.GPUAvailable, "GPU Resources: Available", ..., true} Critical. check --control-plane (or --pre / --all in ModeSingle) therefore schedules a Job on a GPU-less control plane, the Job exits non-zero, clusterValidatorCheck maps Passed=false to severity "error" (preflight.go:601), anyFailed trips, and the command exits 2. Unconditionally.
None of the advertised Gateway API / LB / node-to-node checks exist in the shipped binary either — yet the ClusterRole at L230 grants cluster-wide create/delete on services and daemonsets, pods/log get, and gateway.networking.k8s.io read, with inline comments justifying probes that grep proves absent.
This PR is only correct if #781 (which adds the role parameter and the control-plane check set) merges first. Worth making that dependency explicit in the PR description and, ideally, landing them together.
There was a problem hiding this comment.
Agreed on the ordering; the two PRs are planned to merge together. #781 reads VALIDATOR_ROLE and prints a Validator role line, and until an image with that support is published, a control-plane run whose transcript has no role line but does have the GPU Resources section is reported as a warning that the image predates roles, not as a failed control plane (fbe7599, 178461e, TestClusterValidatorCheck_PreRoleImageIsAWarning). A role-aware image that fails, or a transcript with neither marker, still fails the run. The ClusterRole is trimmed to what the #781 checks call: Services are read-only, pods/log and watch are gone, and DaemonSet create/delete stays for the node-to-node probe (047d62c, TestEnsureClusterValidatorRBAC_LeastPrivilege).

Limit: 1 + len(Items) == 0 is not a valid "nothing matched" test — the apiserver contract explicitly forbids this inference.
From the vendored metav1.ListOptions.Limit godoc (apimachinery types.go:375-382): "Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available."
Namespace nvcf on a healthy install holds dozens of Secrets (SA tokens, TLS, pull secrets) that sort before sh.helm.release.v1.*. The first page scans a non-matching object, returns Items=[] plus a Continue token, and this code concludes "no Helm release". The ConfigMap fallback at L117-120 then hits kube-root-ca.crt (auto-created in every namespace since 1.21) and does the same.
Result: nvcf: no Helm release at error severity, check exits 2, and the remediation tells the operator to kubectl delete namespace nvcf on a live install. ListMeta.Continue is never read anywhere in this file.
Fix: either drop Limit entirely, or loop on Continue until Items is non-empty or Continue == "".
There was a problem hiding this comment.
The probe now follows the Continue token until it finds an owner=helm object or the server reports no more pages, with a 1000-page cap so it always terminates (b8faf70, ce9f770). TestProbeStaleNamespaces_PagesPastNonMatchingObjects pins it with an empty first page that carries a Continue token. A namespace with no Helm release is now also a warning with an inspect command rather than an error with a delete command (bb0d56b, e5ab3dd).

Both lists are wrong in ways that produce error-severity false positives with destructive remediation. Verified against deploy/stacks/self-managed/helmfile.d/ and deploy/stacks/nvcf-compute-plane/helmfile.d/:
nvcf-backendnever hosts a Helm release. It is created at runtime by NVCA (clusteragent/k8s_maintainer.go:51,defaultRequestsNamespace), andself_hosted_down.go:544already states "Workers are operator-managed pods, not a separate helm release." It is on the control-plane list, so in ModeSingle a healthy cluster with running functions reportsnvcf-backend (no Helm release)at error severity, exits 2, and printskubectl delete namespace nvcf-backend— which destroys every live worker.nvca-systemis the same shape on the compute list: operator-created, no release. The only compute-plane release isnvca-operatorin nsnvca-operator.openbao-systemdoes not exist.openbao-serverdeploys tovault-system(01-dependencies.yaml.gotmpl:59-62) — which is already in the list.cert-manager(01-dependencies:53-56) andnvcf-ui(02-core:202-205) are real stack namespaces that are never probed, so acert-managernamespace stuck Terminating silently passes.envoy-gateway-systemis hardcoded while the chart templates{{ .Values.ingress.gatewayApi.controllerNamespace }}(base.yaml:394, default"").
The same false-positive shape hits vault-system / cassandra-system / nats-system whenever they are pre-created by the operator or installed via Argo CD rather than helmfile.
Altitude note: this is now the 5th copy of the NVCF namespace set in this CLI (clusterdump.ControlPlaneNamespaces, self_hosted_up.go:87, pullsecret.go:56, defaultDownReleases) and it already disagrees with all of them. Given the blast radius of the remediation string, deriving from the helmfile release list rather than hardcoding seems worth the effort.
There was a problem hiding this comment.
The static lists now hold only namespaces a helmfile release deploys into: nvcf-backend, nvca-system, openbao-system and envoy-gateway-system are gone, and cert-manager and nvcf-ui are probed (b8faf70, TestControlPlaneNamespaceList_ExcludesRuntimeOwnedNamespaces). With a local stack the list is also derived from the helmfile.d namespace declarations, skipping templated values, and unioned with the static list as a floor (7aba33b, ce9f770, TestResolveStackNamespaces_UnionsStackWithStatic). A namespace with no Helm release, such as vault-system or cert-manager installed outside helmfile, is a warning whose hint inspects the namespace instead of deleting it; only a namespace stuck Terminating fails the run (bb0d56b, e5ab3dd, TestStaleNamespaceCheck_NoHelmReleaseWarnsAndDoesNotSuggestDelete). The other copies of the namespace set elsewhere in the CLI were not consolidated in this PR.

This test mutates whatever cluster is in the developer's current kubecontext.
Its two siblings — TestCheck_ComputePlaneFlagRunsChecks (L435) and TestCheck_ControlPlaneFlagRunsChecks (L467) — both set t.Setenv("NVCF_CLI_SELFHOSTED_SKIP_INOTIFY", "1"). This one sets neither that nor NVCF_CLI_SELFHOSTED_LOCAL_ONLY, and --skip-cluster-validation does not gate the inotify prober. So runPreflightByRole constructs the real NewInotifyProber, which lists every node and creates a privileged busybox:1.36 pod per node in default (inotify_probe.go:40,175).
go test ./cmd/ on an engineer's laptop or a CI runner that happens to have a kubeconfig will write to a live cluster.
Broader: neither of the two new test seams (newStaleNamespaceProberForSelfHosted, newRegistryCredentialCheckerForSelfHosted, self_hosted_check.go:64,72) is stubbed by any test, so all four new cmd tests load the real kubeconfig through the exec credential plugin and make live HTTPS calls — EnumerateRegistries always yields quay.io, so registryChecker is always constructed, at 10s+ per probe on a network-isolated box.
There was a problem hiding this comment.
That test now sets NVCF_CLI_SELFHOSTED_SKIP_INOTIFY like its siblings (ff14b5d). TestMain in cmd/main_test.go also stubs every seam that would reach a cluster or the network by default: the inotify prober, the stale-namespace prober, the registry credential checker and the validator tag lookup (e5ab3dd), plus the validator Job, with SIS pointed at a local test server (d642bef). Tests that exercise a path reassign the seam themselves, as runCheckRecording does for the stale-namespace prober.

ModeSingle still runs both role check sets unconditionally, so now that --control-plane / --compute-plane reach runPreflightByRole, each flag executes the other plane's probes too.
runOnce dispatches on checkPre || checkAll || checkControlPlane || checkComputePlane (L238), but L491-492 call RunPreflightForRole for both roles regardless of which flag was passed. check --control-plane therefore:
- resolves
icmsURL(L400:checkAll || checkComputePlane || !checkPreis true becausecheckPreis false) and fires an HTTP request atsis.nvcf.nvidia.com; - creates busybox probe pods on every node unless
--skip-inotify-checkis passed; - emits
gpu-operator/gpu-node-labelsrows.
None of which the operator asked for.
Separately, computePlaneIsTargeted is referenced only at L146 and L160 — never at the construction site. L417 gates clusterValidator only on clusterValidatorImage != "", unlike cpClusterValidator at L430 which correctly gates on controlPlaneIsTargeted(mode). Consequences: in ModeSplit, --control-plane creates a ServiceAccount, cluster-wide ClusterRole/CRB, pull secret and validator Job in the compute cluster; and in ModeSingle two 5-minute Jobs run sequentially under a 6-minute ceiling that L160 sizes only when both predicates are true — so the second vctx is truncated and reports a spurious context deadline exceeded plus a leaked running Job.
There was a problem hiding this comment.
ModeSingle now runs only the roles the flags select, so --control-plane sends no SIS request, creates no inotify probe pods and emits no GPU rows (ff14b5d, af2c3c3, TestCheck_SISReachabilityScope, TestCheck_StaleNamespacesFollowTheRequestedRoles). The compute-plane validator is gated on the compute plane being visited, the same way the control-plane one is (bb0d56b), and in ModeSplit --control-plane never contacts the compute cluster (46bac78, TestCheck_SplitModeControlPlaneOnlySkipsComputeCluster). Two sequential validator Jobs now run only when both roles are selected in ModeSingle, which is the case the 12 minute ceiling is sized for.

sweepPriorClusterValidatorJobs selects on labels that are identical for both roles, so in ModeSingle the compute-plane run deletes the control-plane run's Job inside the same command — including under --no-cleanup, which makes the printed kubectl logs job/... hint 404. Adding the role to clusterValidatorLabels() would fix both this and the shared-ConfigMap issue above.
There was a problem hiding this comment.
Every object a run creates now carries a role label and a random run ID, and the prior-Job sweep is gone: each Job has an active deadline and a TTL, so a role-wide sweep could only ever hit an overlapping run's live Job (ff14b5d, 6e32129, e5ab3dd). A ModeSingle run therefore cannot delete the other role's Job, and --no-cleanup keeps the Job so the printed kubectl logs hint resolves (3531290, TestRunClusterValidator_NoCleanupKeepsPullSecretAndPriorJob). The ConfigMap is covered in my reply on the ConfigMap thread.

staleNSProber is handed to both RoleConfigs (L464 and L480), so ModeSingle probes twice, emits two check_completed events with the identical ID stale-namespaces, and calls loadKubeConfig twice — two exec-credential-plugin invocations, i.e. a double MFA/tsh challenge per run. cluster-validator has the same duplicate-ID problem. The registry category was explicitly de-duplicated for exactly this reason (preflight.go:348-355); worth doing the same here.
Related, same file: maybeShowClusterValidatorLogs (L349) returns after the first match, so --all --show-logs silently drops one of the two transcripts.
There was a problem hiding this comment.
In ModeSingle the stale-namespace probe now goes to one role only, so there is one stale-namespaces event and one kubeconfig load (ff14b5d); when both roles run, the other role's namespaces are merged into that probe (13ddd00, af2c3c3). --show-logs no longer returns after the first match and prints both transcripts, pinned by TestMaybeShowClusterValidatorLogs_PrintsBothRoles (e5ab3dd). The two cluster-validator results keep one ID on purpose: they are separate Jobs running different check sets, and each is emitted under its own category (control-plane-cluster, compute-plane-cluster).

The security control added in the last commit has zero executable coverage.
TestExchangeBearerToken_DockerHubDelegatedRealm (L388) never calls exchangeBearerToken — it asserts the trustedRealmDelegations map literal against itself, so it passes if the realm check is deleted.
TestExchangeBearerToken_RejectsAttackerRealm (L344) builds a spyTransport and then discards it with _ = spy, and its guard can never fire because the realm check returns before any request is issued. The assertion that no credentials were forwarded is therefore vacuous.
To actually pin this: wire the spyTransport into the client passed to exchangeBearerToken, and assert both the returned error and that spy recorded zero requests carrying an Authorization header.
There was a problem hiding this comment.
Both tests now call exchangeBearerToken (ff14b5d). TestExchangeBearerToken_RejectsAttackerRealm passes a recording transport in the client and asserts the error, that no request carried an Authorization header, and that nothing reached the attacker host; it also configures Docker credentials for the registry (178461e), since NGC_API_KEY never applies to a non-NGC registry and left that assertion vacuous. TestExchangeBearerToken_DockerHubDelegatedRealm drives the auth.docker.io delegation and asserts the token request reached that host.

Three smaller things in this block:
- Source 3 always adds
quay.io, so the registry category (and a 10s probe) runs on every non-local invocation. The rationale is also inverted:global.yaml.gotmpl:78-103mirrors every cert-manager image toglobal.image.registryinstead ofquay.io/jetstack— so on a configured stack this probes a registry the install never contacts. - IPv6 extras lose their brackets:
[::1]:5000round-trips throughparseRegistryHostPort+fmt.Sprintf("%s:%d")into::1:5000, producinghttps://::1:5000/v2/. - Source 1 bypasses
add(L163-166 setsseenand appends directly), which is why it escapes theCriticalpolicy the closure would otherwise apply. Routing it throughaddwith aRepoHintparameter would remove that divergence.
There was a problem hiding this comment.
All three are addressed (b8faf70). quay.io is now probed only when the stack does not override the ACME solver image: global.yaml.gotmpl moves the cert-manager controller images to the mirror, but the solver keeps quay.io/jetstack unless certManager.acmesolver.image is set, so that is the one quay.io pull a mirrored install still makes (d642bef, TestEnumerateRegistries_QuayFollowsTheACMESolverImage). Extras with a port go through net.JoinHostPort, so [::1]:5000 stays bracketed (TestEnumerateRegistries_BracketsIPv6Extras). Source 1 goes through add with a repoHint parameter, so it gets the same host validation and criticality rule as every other source.

The allowlist fails open when u.Hostname() is empty: trustedRealmDelegations[regHost] returns "", which equals realmHost, so https://:443/token satisfies realmOK. The u.Host == "" guard at L202 does not catch it because Host is ":443", not empty.
It is blocked downstream today by the TLS handshake failing, so this is not exploitable as written — but it is a fail-open in a control that was added to fail closed. An explicit realmHost == "" rejection is one line.

In --wait mode an overrun iteration can exit 0 with success:true and zero checks run. Once an iteration overruns the outer ctx, deadline, ticker and ctx.Done are all ready, and select picks one at random. If it picks the ticker branch, runOnce re-runs on the dead ctx, runPreflightImpl returns [] (preflight.go:1044), !anyFailed([]) is true, and the run exits 0 with success:true, verdict ok, 0 checks.
Example: check --pre --wait 15m --json where each validator Job burns its 5m budget (pod Pending, slow pull). A synctest with production budgets gave 8/60 runs exiting 0 with {success:true,verdict:ok,passedCount:0,failedCount:0}, which passes the ci-pipelines.md jq gate and lets up proceed. Another 15/60 exited 1 with no final event, although exit-codes.md promises 5. The mechanism predates the delta, but the delta rewrote both select branches (interrupted()) and still grades DeadlineExceeded as success.
Fix: if ctx.Err() != nil after runOnce, emit a failed/timeout final and exit 5, and check the deadline before the ticker.
There was a problem hiding this comment.
Fixed. The wait loop checks the context after every iteration and checks the deadline before the ticker, so a dead context can no longer start another pass. A budget that runs out now ends with exit 5 and a final event, never with success on zero checks (698d4bf, TestCheck_BudgetSpentIsATimeout, _BudgetSpentIsATimeoutEvenWhenRowsPassed).

There was a problem hiding this comment.
When the outer budget expires mid-run, every unstarted check is silently dropped, including the cluster-validator. Here the cause is DeadlineExceeded, not a signal. runSelfHostedCheck then grades the partial set as the verdict.
Example: split check --pre --json with a validator image, on a ~33-node compute cluster where the busybox inotify probe pods can't start (air-gapped, or Docker Hub throttled). The probe consumes the 6m budget and degrades to a warning. The compute-plane validator, which carries the critical GPU checks, never starts. The final event is {success:true,verdict:warnings} and the exit code is 0. With 24 nodes the validator does run and the command exits 2.
This contradicts 0d240a8's own rule that a validator that could not run must fail the gate; interrupted() only covers signals. Emit a "not run (budget exhausted)" error row for every unstarted check.
There was a problem hiding this comment.
Fixed. When the budget runs out, every check that has not started gets an error row, "not run: the check's time budget ran out before it started", and the run exits 5. A signal is still handled separately: exit 130 with a cancelled final event and no rows (698d4bf, TestRunPreflight_BudgetSpentChecksAreNotRunErrors, TestCheck_BudgetSpentIsATimeout).

On interrupt, the CLI revokes the validator's RBAC before the validator can clean up its own probe resources, so they leak. It deletes the Job with Background propagation and immediately sweeps the SA/ClusterRole/CRB, before the pod has received SIGTERM. #781's SIGTERM cleanup of its node-to-node probe then runs with revoked credentials.
Reproduced on a 2-node k3d (CLI ff98280, validator 542cebe): Ctrl-C or CI SIGTERM during check --control-plane/--pre/--all while #781 is in checkNodeToNode. The validator logs "Failed to clean up probe namespace nvcf-n2n-validation-...: cannot delete resource namespaces". 45s later the namespace was still there, along with a DaemonSet running while true; do nc -l -p 19999; done on every node, the control-plane node included. 6 of 7 trials leaked at local latency. Only a later control-plane validator run's 10-minute orphan sweep reclaims them. Before 178461e the Job finished with its RBAC intact and cleaned up after itself.
Fix: delete with Foreground propagation, wait (bounded, e.g. 30s) for the pod to be gone, then sweep the RBAC.
There was a problem hiding this comment.
Fixed. On interrupt the CLI now deletes the Job with Foreground propagation and waits, for a bounded time, until the validator pod has ended. Only then does it sweep the SA, ClusterRole and binding, so the pod's SIGTERM cleanup still has its credentials. If the pod does not end in time, the RBAC is kept and the result prints the command that removes it. Also covered against an in-memory apiserver, so the DELETEs are checked on the wire and not only on the fake clientset (698d4bf, TestRunClusterValidator_InterruptStopsTheJobInTheForeground, _PodThatWillNotEndKeepsItsRBAC, _InterruptSendsCleanupOverTheWire).

The legacy-image check turns real control-plane failures into a non-blocking warning. The downgrade runs before the pass/fail branch and ignores which rows failed. The pre-#781 image does catch some real failures: Control Plane /readyz, Admission Webhooks, and critical registry reachability from this CLI's ConfigMap. All of them now become a warning.
This happens on every run today. The newest stable NGC tag, 3.2.26 (2026-09-29), predates #781; its binary doesn't contain Validator role: . So every untagged cluster_validator_image resolves to it. A post-install check --control-plane --json on a control plane with a failing /readyz, or with no route to the critical nvcr.io endpoint, produces a transcript with "Control Plane: Unhealthy" or Endpoint Reachability failures plus "GPU Resources". That becomes a warning, {success:true,verdict:warnings}, exit 0. At 02d5ade it exited 2. The failure is fully masked for --control-plane and for the control-plane cluster in split --pre/--all. If pod logs can't be read (the error is discarded at clustervalidator.go:293), a legacy run still exits 2.
The detection itself is sound: it requires both a missing role marker and a present "GPU Resources" section, and #781 prints the marker before any early return. The problem is what happens after detection. Either put a role-aware minimum-version floor at tag resolution, or downgrade only when the sole failed critical row is GPU Resources.
There was a problem hiding this comment.
Fixed. The downgrade is now scoped. It applies only when the image has no role marker and GPU Resources is the only failed critical row in the validator's summary. A failing /readyz, admission webhook or reachability row keeps the result an error (698d4bf, TestClusterValidatorCheck_PreRoleImageIsAWarning).

Found from the #781 side. This treats Job success as a clean pass and drops the validator's warnings. Now that #781 exits 0 on tolerated rollouts, check --wait stops polling in the middle of an upgrade.
Example: straight after an upgrade sync, NATS is at 2/3 mid-RollingUpdate, or nvcf-api is at 3/4 mid-rollout. The validator returns "NVCF-Ready (with warnings)" with exit 0. This records Passed: Succeeded>0 (clustervalidator.go:333) with severity info, and anyFailed stops --wait (self_hosted_check.go:327). An end-to-end CLI run returned verdict ok after 1 iteration; at round 3 it kept polling until the rollout finished. #782's docs say check --control-plane --wait "polls until pass".
Parse the validator's verdict line (NVCF-Ready (with warnings)) and map it to a warning-severity result that --wait keeps polling on.
There was a problem hiding this comment.
Fixed. The CLI reads the validator's verdict line. "NVCF-Ready (with warnings)" becomes a warning row, marked transient when the warnings name a rollout in progress. --wait keeps polling while a transient warning remains (698d4bf, TestClusterValidatorCheck_PassWithWarnings, TestCheck_WaitPollsOnARolloutInProgress).

This HELM_DRIVER gate, which I suggested in round 3, makes the "no Helm release" signal fire on the documented fresh-install state. It also fires on Argo CD installs, which use helm template and leave no release object. It's a warning with a hint that nudges operators to delete the namespaces.
Following docs/self-managed/helmfile-installation.md (~794-810), the operator pre-creates cassandra-system, nats-system, nvcf, api-keys, ess, sis, vault-system and others, each holding only nvcr-pull-secret, then runs check --pre as SKILL.md says. This head reports "8 stale namespace(s) detected ... (no Helm release)" with "remove it only after confirming it is unused"; 02d5ade reported none. Deleting them removes the pull secrets up expects when NGC_API_KEY is unset.
"No Helm release" is only meaningful once an install has happened. Gate it on --pre being false, or skip namespaces whose only objects are dockerconfigjson Secrets.
There was a problem hiding this comment.
Fixed with the second option, plus one case for Argo CD. A namespace without a release is not flagged when it only holds registry pull Secrets (with the service account tokens and kube-root-ca.crt every namespace has, and no PVCs), or when it runs any pod. What down leaves behind runs nothing and still holds data, so that is still reported (183583a, TestProbeStaleNamespaces_PreCreatedNamespaceIsNotStale, _NamespaceRunningPodsIsNotStale).

Round-3 #21 is partly fixed. These lifecycle tests use a fake clientset that ignores contexts and never inspects delete options, so the delta's key cleanup guards can regress with the suite green. Each of these mutations, applied alone, survives go test ./internal/selfhosted/:
- deriving the sweep contexts from the cancelled run ctx (on a real apiserver, Ctrl-C then sends 0 of 6 DELETEs);
if pullSecret != ""instead of the run-name check (the operator's own Secret gets a Job ownerRef and is GC'd);- dropping
&& !noCleanupfrom the interrupt or pull-failure branch (a--no-cleanuprun is deleted); - Orphan propagation (the pod outlives its Job);
- an unbounded
deleteValidatorJob(hangs on a dead apiserver).
Removing the deferred sweeps, the interrupt/pull-failure branches, ownByJob or the exact-name match is caught. A reactor that records DeleteOptions and each call's ctx.Err() would pin the rest.

Each of these mutations is now caught. The new tests check the delete propagation and the operator Secret's owner references, plus the --no-cleanup branches and the pod outliving its Job. Cleanup contexts and bounded deletes are checked against an in-memory apiserver that counts the DELETEs on the wire and can hang them (698d4bf, TestRunClusterValidator_InterruptSendsCleanupOverTheWire, _HungDeletesAreBounded, _OperatorPullSecretIsNeverOwned, _NoCleanupKeepsArtifactsUnowned, _InterruptStopsTheJobInTheForeground).

Round-3 #19/#11 are partly fixed. resetCheckFlags clears cobra's Changed markers but not persistent flag values, and this TestMain doesn't isolate HOME, so check tests are still order- and machine-dependent.

Fixed. TestMain points HOME at a temp dir, so ~/.nvcf-cli.yaml is not read and ~/.nvcf-cli.state is not written (I checked the real state file's mtime across a full run). resetCheckFlags now restores each flag's value from DefValue, not only Changed. The probe-image test sets the flag instead of calling viper.Set. Your repro passes, and -run TestCheck_ passes for 12 of 12 shuffle seeds; with the value reset removed, it fails again (183583a).

Round-3 #5 is partly fixed. The probe-image override reaches #781, but it only helps mirrors that allow anonymous pulls: #781 runs the node-to-node DaemonSet and checker in a fresh namespace with no imagePullSecrets. The default is still Docker Hub busybox:1.36, and the config key is missing from .nvcf-cli.yaml.template.
Example: a multi-node control plane on a mirror that needs credentials (the stack's global.imagePullSecrets shape, no node-level credentials). check --pre --cluster-validator-probe-image harbor.corp/library/busybox:1.36 gives ErrImagePull on every node, then a critical Node-to-Node "Status Unknown", then exit 2. With the defaults, an air-gapped cluster fails the same way. This stays hidden until a #781 image runs. The fix spans both PRs: #781's probe namespace needs the run's pull secret, or the image needs to come from the already-authorized validator registry.
There was a problem hiding this comment.
Partly addressed: cluster_validator_probe_image is now documented in .nvcf-cli.yaml.template (183583a). Credentialed mirrors need a change in #781 too: the probe namespace needs the run's pull secret, or the probe image should default to the validator's own, already authorized, registry. I'd like to do that as a follow-up across both PRs rather than grow this one further.

Smaller items from this round:
- This comment is stale: after the managed-by rename, the sweep no longer matches on the shared name prefix alone.
TestRunClusterValidator_HappyPathstill asserts the removed prior-Job sweep.--wait --no-cleanupstill keeps a full preserved set per poll, and a pull failure under--no-cleanupretries forever with no deadline.--pre --allprobes SIS as post-install but withholdsVALIDATOR_POST_INSTALL.- On a pull failure, the row's hint still points at the Job that was just deleted.
- An interrupted in-flight check is emitted as an error row before the cancelled final event.
- The SIS gate reduces to
checkAll || checkComputePlane. ci-pipelines.md:32(em-dash) andflags.md:15-17(U+2026) weren't normalized, although the delta touched both files (root AGENTS.md; the documentation-style skill says to normalize "when you touch that file").
There was a problem hiding this comment.
All addressed. The sweep comment is updated and the HappyPath assertion replaced. --wait --no-cleanup is rejected, and a pull failure under --no-cleanup suspends the Job. A pull failure's hint no longer points at the deleted Job, and an interrupted check ends with the cancelled final event and no error row (698d4bf). In 183583a: the SIS gate is now checkAll || checkComputePlane. --pre --all sends VALIDATOR_POST_INSTALL to both roles, and a role's own flag with --pre sends it to that role (TestCheck_PreSplitRunsBothValidatorRoles). ci-pipelines.md and flags.md are normalized to ASCII.

TL;DR
Adds three capabilities to
nvcf self-hosted check: a control-plane clustervalidator (wired to the companion nvca PR #781), stale-namespace detection
before install, and pre-install registry credential validation over the generic
OCI Bearer token flow.
--compute-planewas previously a no-op and now works.Review of the first implementation found that everything the validator creates
in the cluster was named predictably and owned by labels alone, so the resource
lifecycle was reworked to per-run, unguessable names.

The pull Secret and the network-checks ConfigMap were created under predictable
names and owned by labels alone. The managed labels are three public constants,
so anyone able to create objects in the validator's namespace could pre-create
either name wearing them, pass the ownership check, and receive whatever the run
wrote there. For the Secret that is the NGC credential.
Both names now carry the run's unguessable suffix, matching what the RBAC
objects already did, and the Secret write is create-only: nothing this CLI
created can already hold a name it just generated, so
AlreadyExistsmeansanother object does and erroring beats overwriting.
Run-scoping also removes two lifetime conflicts. Two overlapping commands no
longer share one ConfigMap, where the first to finish deleted config the other
pod had not read yet; and one run's sweep can no longer delete a Secret another
run selected. It cost the accidental self-healing a fixed name gave us, so the
orphan sweeper gained Secret and ConfigMap arms.

Validator result handling

nodes often pull through a proxy or mirror, so a failed in-pod dial is a
warning. The local credential check still fails a registry the install cannot
pull from.
Credential handling
NGC_API_KEYis only minted for NGC registries. An operator mirroring thevalidator image to
ghcr.ioor a corporate Harbor would otherwise have thekubelet send the live key there as HTTP Basic auth.
For an NGC registry the credential check uses

Two conditions are reported. A namespace stuck Terminating fails the run. "No
Helm release" warns, and is not reported:
HELM_DRIVER=sql, which keeps release state outside the cluster;documented install pre-creates them;
helm templateby Argo CD.What
downleaves behind runs nothing and still holds data, so it is stillreported.
The remediation inspects rather than deletes. The stack gates cert-manager,
NATS, OpenBao and Cassandra on
*.enabled, so an operator who installs one thedocumented upstream way owns a healthy namespace with no
owner=helmobject;the previous
kubectl delete namespace cert-managerwould have destroyed everyCertificate and Issuer in the cluster.
JSON contract
successand the exit code now derive from one predicate. A warning-severityresult previously emitted
success:falseandverdict:failedwhile the processexited 0, so a CI gate on
final.successbroke for every user whose registrycredentials live in a Docker credential helper. The already-documented
warningsverdict is now emitted.For the Reviewer

cmd/main_test.go: the seams that make the package hermetic.Worth reading the commit body on
fe418ddf0: the security rationale forcreate-only writes and run-scoped names is the part that cannot be inferred from
the diff.
For QA
go build,go vetand the full module suite pass; all 21 bazel targets pass.The
cmdpackage is hermetic. It previously created a hostPath busybox pod pernode in
default, listed Secrets across the stack namespaces of whateverkubeconfig happened to be current, and made an outbound request per configured
registry.
TestMainstubs those seams and pointsHOMEat a temp dir, so thedeveloper's
~/.nvcf-cli.yamlis not read and~/.nvcf-cli.stateis notwritten. Check tests reset flag values between runs and pass under
-shuffle(12 of 12 seeds).Cleanup on interrupt and bounded deletes are also tested against an in-memory
apiserver, so the DELETE requests and their propagation are checked on the wire
and not only on the fake clientset.
Behavioural guards are mutation-tested: each was verified by breaking it and
confirming a test fails.

Merge order: this depends on #781, which must merge first.
VALIDATOR_ROLEisset on the Job here but nothing reads it until #781 lands. Until then an image
built before #781 runs the compute-plane check set on the control plane; its
GPU Resources failure is reported as a warning.
Deferred: making the validator namespace configurable rather than the
defaultconstant; and pulling the node-to-node probe image from a mirror that needs
credentials, which needs a change in #781 as well (the probe namespace needs
the run's pull secret, or the probe image should default to the validator's
registry).
