fix(nvcf-cli): fail self-hosted check --control-plane and --compute-plane instead of reporting a vacuous pass

[rohithb-hub]

TL;DR

nvcf-cli self-hosted check --control-plane (and --compute-plane) ran no checks and reported success: true, verdict: "ok", exit 0. They now report a failed check saying the health checks are not implemented, and exit 2.

Additional Details

• Problem: the flags are accepted by the parser and then ignored in runSelfHostedCheck. With zero checks, emitCheckFinal sees no failures and emits verdict: ok. A post-install validation script gets a clean pass without anything having been verified.
• Fix, all in cmd/self_hosted_check.go:
  • --control-plane and --compute-plane each emit one failed check (control-plane-health, compute-plane-health, severity error) and exit 2.
  • --wait returns at once for these, since polling cannot make them pass.
  • ensureChecksRan turns any run that executed zero checks into a no-checks-run failure, so an empty result set can never read as ok.
  • --all is unchanged: it still means every available check (the --pre set) and does not add the new failures.
  • Flag help no longer advertises working health checks.
• The nvcf-self-managed-cli skill reference and multi-cluster example no longer describe these flags as working (they point to self-hosted status and cluster-agent validate). skilldata_generated.go is regenerated with go generate; its diff is large because the embedded data is regenerated as a whole.
• Limitation: this does not implement the control-plane or compute-plane probes. It only stops the false success. Real in-cluster checks are being built separately on the cluster-validator work (feat(nvca): extend control-plane validator with HA checks, DaemonSet n2n, and route CR type check #781, feat(check): add control-plane validator, stale namespace detection, and registry credential checks #782). The guard stays as a backstop once those land. Expect a small textual conflict with feat(check): add control-plane validator, stale namespace detection, and registry credential checks #782 in runOnce and emitCheckFinal.

For the Reviewer

• cmd/self_hosted_check.go: new helpers emitFailedCheck, unimplementedCategoryResults, ensureChecksRan, failedChecksExit, and the wait-loop short-circuit.
• Behavior change: scripts that pass --control-plane or --compute-plane today get exit 2 instead of 0. That is the intent, since those runs verified nothing.

For QA

• Unit tests in cmd/self_hosted_check_test.go: both flags fail with exit 2 and a failed final event, --wait returns without polling, --all does not add the new rows, and ensureChecksRan covers empty and non-empty results.
• go test ./cmd/ ./internal/selfhosted/... ./internal/agentskill/... passes.
• Manual, against a local k3d cluster where nvcf-api and the SIS service were crash-looping: before, check --control-plane --json printed {"success":true,"verdict":"ok","passedCount":0,"failedCount":0} and exited 0. After, it prints a failed control-plane-health check, {"success":false,"verdict":"failed","failedCount":1}, and exits 2. --wait 1m returns immediately. check --all --local-only is still ok.
• QA is not needed beyond this.

Summary by CodeRabbit

• Bug Fixes
  • Selecting the control-plane or compute-plane check now reports a failure and exits with code 2. These checks fail immediately, even when waiting is requested.
  • The “check all” option no longer reports unimplemented control-plane or compute-plane checks.
  • Runs with no checks now report a failure instead of appearing successful.
• Documentation
  • Updated the setup example to use the self-hosted status command.

📝 Walkthrough

Walkthrough

The self-hosted CLI now reports selected control-plane and compute-plane checks as unimplemented failures. It exits with code 2, including in wait mode. The command reference and multi-cluster example reflect the updated check behavior.

Changes

Self-hosted check behavior

Layer / File(s)	Summary
Report unimplemented checks and update guidance src/clis/nvcf-cli/cmd/self_hosted_check.go, src/clis/nvcf-cli/cmd/self_hosted_check_test.go, ai-tooling/user/skills/nvcf-self-managed-cli/reference/commands.md, ai-tooling/user/skills/nvcf-self-managed-cli/examples/multi-cluster.md	Selected control-plane and compute-plane checks produce failed results and exit with code 2. Wait mode returns without polling when an unimplemented check is selected. Empty check results produce a failed result. Tests cover these behaviors, and the reference and example describe the updated commands.

Change: Bug fix

Merge Risk: ⚪ Minimal · up to c58be

This change makes the self-hosted check flags fail explicitly instead of reporting success when no checks run, and updates the guidance to match. No remaining merge-blocking risk is evident from the reviewed change.
