fix(bundler): translate helm connection flags for the CRD step

[mchmarny]

Summary

The CRD pre-apply step added in #2725 forwarded KUBECONFIG_FLAG straight to
kubectl. That variable carries helm's spelling of the connection options,
and kubectl has no --kube-context flag, so any deploy naming a context died
with unknown flag: --kube-context before a CRD was applied. Translate the
value instead of forwarding it, and widen three E2E path filters so the lanes
that execute these generated scripts actually run when the templates change.

Motivation / Context

#2725 landed on main at 22:50Z and broke the NPD Object Monitor, NVSentinel
Object Monitor, and NVSentinel Preflight E2E lanes. It surfaced on #2829, which
was merely the first PR to rebase onto it and touch a triggering path — that PR
is unrelated to the break.

Those three lanes never ran on #2725 itself: their path filters deliberately
exclude pkg/bundler/**, and main's push run is filtered the same way, so the
regression reached main unexercised. That gap is the second commit here.

Implementation Notes

Translate, don't add a second env slot. A parallel KUBECTL_FLAG would be
fail-open: every existing caller sets only KUBECONFIG_FLAG — including all
four tests/e2e/* harnesses and anyone following the deploy.sh banner — so
they would silently force-apply cluster-scoped CRDs against the ambient
context. Translation needs no caller, doc, or golden changes.

Scope of the translation. Only --kube-context (→ --context) and
--kubeconfig (identical) are mapped, in both =-joined and space-separated
forms. Anything else fails closed with an actionable message. This regresses
nobody: on current main a helm-only flag like --kube-token already dies on
kubectl's arg parser — this just replaces a confusing error with a clear one.
Extending to the full helm→kubectl flag map is deliberately out of scope for a
hotfix; say the word if you'd rather have it here.

${KUBECTL_CONN[@]+...} is load-bearing. Stock macOS ships bash 3.2, which
errors on an empty-array expansion under set -u. This script already caters to
that platform (the gtimeout fallback), so the guard is required, not style.

The path-filter carve-out is narrow on purpose — the localformat template
directory only, not pkg/bundler/**. Each lane costs a Kind spin-up and a full
NVSentinel image pull. I extended each workflow's "deliberately narrow" header
comment to explain the exception, so the new entry doesn't read as contradicting
the comment above it.

Testing

make qualify   # exit 0

Stage	Result
Coverage	84.9% (threshold 83%)
Tests (-race)	no failures
e2e / chainsaw	29 passed, 0 failed, 0 skipped
Vulnerability scan	2 findings, both pre-existing on main
api-diff	no incompatible SDK changes since v0.21.0
openapi-diff	no unacknowledged REST breaking changes

Beyond the suite, I executed the rendered script against stub helm/kubectl
binaries (the stub kubectl rejects --kube-context exactly as the real one
does), since a golden diff cannot show that the flags actually parse:

KUBECONFIG_FLAG	Result
(empty)	rc=0, no flags added — incl. /bin/bash 3.2
--kube-context kind-aicr	helm keeps --kube-context; both kubectl calls get --context
--kube-context=kind-aicr	same
--kubeconfig /tmp/kc.yaml	passes through unchanged
--kubeconfig=... --kube-context ...	both translated
--kube-apiserver https://x	rc=1, fails closed
--kube-context (no value)	rc=1, fails closed

TestApplyCRDsScript_GatesAndBounds pins the two call sites by exact text, so a
future -update regenerating goldens cannot silently bless a revert; I
repointed those two entries and added two covering the translation and its
fail-closed branch.

No production Go code changed — the only .go edit is test assertions — so
package coverage is unaffected.

Risk Assessment

• Low — Isolated change, well-tested, easy to revert
• Medium — Touches multiple components or has broader impact
• High — Breaking change, affects critical paths, or complex rollout

Rollout notes: None. Regenerated goldens are deterministic; the only
stock_render_golden.yaml churn is *-nvsentinel/apply-crds.sh hashes and
their rollup checksums.txt entries, nvsentinel being the sole ownsCRDs
component in the stock render.

Checklist

• Tests pass locally (make test with -race)
• Linter passes (make lint)
• I did not skip/disable tests to make CI green
• I added/updated tests for new functionality
• I updated docs if user-facing behavior changed (N/A — no user-facing surface)
• Changes follow existing patterns in the codebase
• Commits are cryptographically signed (git commit -S)

📝 Walkthrough

Walkthrough

The CRD scripts now translate Helm connection flags into validated kubectl arguments. They support separate and =value forms for --kube-context and --kubeconfig, and reject unsupported or incomplete options. CRD lookup and application use the translated arguments. Generated scripts, tests, and render golden data were updated. Three NVSentinel E2E workflows now trigger for localformat template changes.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix

Suggested reviewers: lockwobr

Merge Risk: 🟡 Moderate · up to ccdb1

Malformed connection options can cause CRDs to be applied using ambient cluster configuration rather than failing, risking deployment to the wrong cluster. Add the missing parser validation before merge.

Verified the fix at 61ac566f. Both kubectl call sites take the translated array, helm list correctly keeps helm's spelling, and install-upstream-helm.sh.tmpl / install-local-helm.sh.tmpl pass KUBECONFIG_FLAG only to helm — so apply-crds.sh was the sole kubectl consumer and the fix is complete on that axis. NPD Object Monitor E2E went green on the prior head and nothing is failing on this one. The execution-based translation test is good coverage: it runs the generated script against recording stubs and asserts on logged argv, with denyArgs so a case can't pass by leaving the helm spelling in place.

One item worth following up, not blocking.

The catch-all at templates/apply-crds.sh.tmpl:95 interpolates the flag's value.

KUBECONFIG_FLAG may carry helm's --kube-token=<bearer>, which reaches the catch-all and is printed whole:

ERROR: KUBECONFIG_FLAG carries '--kube-token=SUPERSECRET', which has no known

deploy.sh.tmpl:391 invokes install.sh without redirecting its output, so the token reaches the terminal and CI logs directly, and the surrounding retry can repeat it. The previous kubectl failure exposed only unknown flag: --kube-token, so this is a disclosure the PR introduces. Lines 68 and 83 already strip correctly, so it is one spot rather than a pattern.

The same line also overstates the reason. Several rejected helm flags do have kubectl equivalents — --kube-token is --token, --kube-apiserver is --server, --kube-ca-file is --certificate-authority — and not translating them is an intentional scope call, not an absence of a spelling.

Both resolve in one edit:

echo "ERROR: KUBECONFIG_FLAG carries '${helm_conn[0]%%=*}', which this CRD step does not support." >&2

Same "not supported by this CRD step" wording in the generated README. Worth adding a joined-token case to TestApplyCRDsScript_TranslatesHelmConnectionFlags that asserts the marker value is absent from the captured output — the existing wantErr rows check exit status only, so nothing currently guards this.

Out of scope, not raised as a finding: the parse/reject block now runs ahead of the "chart ships no CRDs" exit, so an ownsCRDs component whose pinned chart ships none would abort where it previously no-opped. No currently supported ownsCRDs chart has that shape, so it is not reachable in this PR's scope. Lazily parsing connection flags for a future zero-CRD chart is a separate concern.

[mchmarny]

@yuanchen8911 the follow-up from your review is up as #2856.

Verified all three points before implementing:

• The joined form did leak. The separated form did not — it exits on the flag name before reaching the value. Both are covered by tests now, since the asymmetry isn't obvious from the code.
• Real kubectl prints error: unknown flag: --kube-token with the value stripped, so this was a disclosure fix(bundler): translate helm connection flags for the CRD step #2849 introduced rather than one it inherited. Your read was right.
• --token, --server and --certificate-authority all exist, so "no known kubectl spelling" was false. Message and generated README both reworded to say the step does not support them.

Took the ${helm_conn[0]%%=*} edit as suggested. The rejection rows previously asserted exit status only and now also assert the argument is absent from output; I repointed the GatesAndBounds block pin to the redacting expansion itself, so removing the redaction fails the unit suite rather than only the new row.

Left the ordering item alone — the parse block running ahead of the "chart ships no CRDs" exit — since you raised it as out of scope and no currently supported ownsCRDs chart has that shape.
