Handle an empty RUNTIME_REQUIRED_TAINT value instead of failing closed.
When the first matching EnvVar has an empty Value, runtimeRequiredTaints passes it to snapshotter.ParseTaint, which returns taint string cannot be empty. The validator then returns ErrCodeInvalidRequest instead of using the chart defaults. Treat an empty value as unconfigured, matching remove_stale_nodewright_taints.

There was a problem hiding this comment.
MINOR: This newly added sentence calls v0.18.0 "the pinned version," but this patch sets the registry pin to v0.19.0. The same stale pin claim appears in the health-check comment and upgrade-record header, so readers and maintainers get conflicting current-version and boundary context.
Minimum correction: Describe v0.18.0 as the rename boundary and v0.19.0 as the current pin, and remove the duplicated v0.19.0 preface.
|
Responded to the review in Taint cleanup could strip a live gate (
|
| Chart | name: |
Rendered app.kubernetes.io/name |
|---|---|---|
| v0.15.1 | skyhook-operator |
skyhook-operator |
| v0.17.1 / v0.19.0 | nodewright |
nodewright |
So the exposure is a cluster installed from an AICR bundle pinned at v0.15.1 — before #1348 moved the pin to v0.17.0. The label finds nothing, fresh_deploy=true, and the cleanup strips runtime-required taints while that operator is still running.
The Deployment name is stable across both chart eras (fullnameOverride: skyhook-operator), so the guard now does a second lookup by name. It uses a field selector rather than a named get, so an absent Deployment is an empty list rather than an error and both queries keep the same shape; either failing still skips the cleanup rather than concluding the operator is gone. Deliberately not deduplicated — the current install matches both queries, and a duplicate row changes neither the emptiness test nor the active-replica scan.
Two cases added to tools/deploy-sh-taint-cleanup_test.sh. Both fail without the fix, the first by issuing the call it exists to prevent:
FAIL: legacy-labelled-operator-no-taint-calls
expected no kubectl taint calls, got: taint node gpu-1 nodewright.nvidia.com-
Note this leaves the guard matching on either name or label, which is deliberate given #2599 wants to move the validator the other way (name → label) for out-of-band installs. Neither identifier alone covers both cases.
Value-gated health-check wording (nodewright.md) — fixed, and the catch was right
This one was my error. Resolving the rebase against #2772 I preserved main's "Known limitation … aicr validate --phase deployment fails that check" wording, reasoning that a static Chainsaw assert cannot read effective values. It cannot — but gatedHealthCheckSuppressed suppresses it at the validator level, so the limitation no longer holds and I had reintroduced stale text. Rewritten to describe the actual behavior, including that the suppression is fail-closed: a render, read or discovery error propagates rather than reading as "nothing to assert".
Stale pin references — fixed
v0.18.0 was described as the pinned version in three places (nodewright.md, the nodewright-customizations health-check comment, the transition-record header) when the registry pins v0.19.0. All now describe v0.18.0 as the rename boundary. The duplicated preface in the transition record was an editing slip on my side and is gone.
record-blocks documentation — fixed
Correct: matchVersions reaches lowestBlocked only after the single-crossed-record branch, so a blocked record whose from does cover the source still yields record-blocks when another boundary is crossed alongside it. The table row now covers that case.
Empty RUNTIME_REQUIRED_TAINT → chart defaults — not taken
Keeping this fail-closed, with a better message instead (c8dc2b2ce, which predates the comment).
The operator's own options validation requires a runtime-required taint and refuses to start without one (skyhook_controller.go: "runtime required taint must be set"). So an empty value does not mean "unconfigured" — it means the operator is not running. Falling back to chart defaults would make the gate wait on taints that a non-running operator will never remove, turning a one-line configuration error into an 8-minute timeout reporting "taint never cleared". That is a worse diagnostic for the same underlying fault.
What did change: the three cases are now distinguished rather than all reporting "is not a valid taint" — empty (the operator will not start), valueFrom (unresolvable from the Deployment spec, since the gate reads it there), and genuinely malformed. All still fail closed, with table cases for each.
Out-of-scope pre-merge warning
Each flagged change is consequent to the pin bump rather than unrelated, and the PR description covers the reasoning:
pkg/upgrade/match.go— recording the v0.19.0 boundary exposed thatmultiple-boundariescounted crossedsaferecords, which carry no steps by construction, so a v0.16 → v0.19 jump was told to stop at v0.18.0 where landing changes no work.pkg/snapshotter/agent.go—ParseTaintnow validates key and value syntax, because it is newly load-bearing: the taint gate parses an operator-supplied env value that reaches a generatedkubectl taintcommand.recipes/components/nodewright-operator/values.yaml—webhook.removalImageexisted only to qualify a short-name image that v0.18.0 qualifies upstream; the BOM confirms an identical digest.
Separately
Two robustness points in resolveNodewrightGVR are filed separately rather than expanded here: discovery is checked at group/version granularity rather than for the resource itself, and the GVR is resolved once ahead of an 8-minute poll, so a validator racing a fresh install can skip the check entirely. The second is pre-existing #607 behavior rather than new in this PR.

Reviewed through f0a2f6f. One blocking validation defect, one correctness issue in new code, and one stale comment.
Blocking — recipes/checks/rdma-netns-exclusive/health-check.yaml:56-65 still waits for status.status: complete on the legacy Skyhook object. From v0.18.0 the operator mirrors that object into a NodeWright and writes completion status there, leaving the legacy status unset. Because v0.19.0 still serves the Skyhook CRD, the assertion consumes its full six-minute timeout rather than failing fast, even on a cluster where the tuning completed successfully.
This PR's pin bump is what makes that path reachable. Both VR200 overlays enable the check and inherit v0.19.0, with neither a suppression entry nor another readiness probe. It is the same status-migration defect this PR already fixes for nodewright-customizations. That file is untouched by the diff, so this could not be left as an inline comment.
Please make the asserted kind follow the operator generation. If pre-rename recipes remain supported, preserve a readiness signal for both generations rather than suppressing the check entirely.
The remaining two items are inline: the runtime-required-taint gate resolves the operator Deployment by a single name, and one comment still identifies v0.18.0 as the current pin.
Verdict: Request changes, because the inherited RDMA health check fails under the version introduced by this PR.

This looks up only skyhook-operator-controller-manager and silently returns chartDefaults() on IsNotFound.
The VR200 overlays explicitly support both installation paths: the AICR-managed operator renders that name, while the documented out-of-band installation renders nodewright-controller-manager (vr200-rke2-ubuntu-training.yaml:176-192, which is why that overlay's own Deployment assert is deliberately name-agnostic). On the latter path the gate ignores a custom live RUNTIME_REQUIRED_TAINT and waits only for the chart-default taints.
Please probe both supported names, use the live configuration when exactly one exists, and fail closed if both are present.

This still identifies v0.18.0 as the current pin; the registry pins v0.19.0 and the ceiling is <=0.19.0, which lines 19-22 just below describe correctly. v0.18.0 is the rename release.

Both items are addressed in ab284a2. Thanks for the quick turnaround.
The RDMA check now asserts the NodeWright kind, which matches how nodewright-customizations already asserts it, so the two checks take a consistent position on the rename rather than one trailing the other. Pinning the name across the mirror is fine given the component ships a single CR.
The taint gate now probes both supported Deployment names, uses the one that exists, returns a conflict when both do, and still falls back to chart defaults only when neither is present. That covers the out-of-band install path the VR200 overlays document.
Verified locally at this head: go build ./... is clean, ./validators/deployment/... passes, and TestCatalogParityGolden plus ./pkg/bundler pass against the regenerated golden files. I did not run the full make qualify.

Reviewed ab284a26f. The flux regrouping and the rdma-netns-exclusive retarget both look right.
On the two-record question I checked it rather than taking the argument: deleting the safe record fails rule 3 with exactly the gap you described (leaves a version gap between 0.18.0 and the pinned version 0.19.0 that no record describes), and v0.17.1 -> v0.19.0 does come back manual with the rename steps. So the split is load-bearing, not stylistic.
One item below I would act on before merge (loneSubstantive on an all-safe crossing). The rest are nits.
Separately, the empty RUNTIME_REQUIRED_TAINT thread reads settled to me. The counter-argument rested on the chart not validating the value; you cited the operator refusing to start without one, which is the evidence that decides it.

There was a problem hiding this comment.
loneSubstantive returns false when found == 0, so a jump that crosses only safe boundaries still falls through to ReasonMultipleBoundaries and reports blocked.
That contradicts the branch's own premise: if one safe boundary composes nothing and skips nothing, N of them compose nothing either. Reproduced against a synthetic two-safe record on this head:
v1.0.0 -> v1.2.0 verdict=blocked reason=multiple-boundaries
crosses 2 recorded boundaries (1.1.0, 1.2.0); no single record describes the
whole jump. Upgrade to 1.1.0 first, then re-run this check
Not reachable with today's data (nodewright has exactly one safe record), but it lands the moment a second one does, and it lands as a blocked verdict telling an operator to stop somewhere that asks nothing of them. The three new cases in match_test.go are manual plus safe, safe alone, and two substantive, so nothing pins this one.
Returning any of the crossed safe boundaries when found == 0 closes it, plus a control case.
There was a problem hiding this comment.
Agreed, and I verified it independently at ab284a2 rather than just reading your repro — loneSubstantive ends with return only, found == 1, so an all-safe crossing leaves found at 0, returns false, and falls through to blocked / multiple-boundaries.

Minor, same branch. When the lone substantive record's ceiling stops short of the target, this bails to the multiple-boundaries message rather than beyond-record-ceiling, and the two name different places to stop:
v0.17.1 -> v0.20.0 blocked reason=multiple-boundaries
crosses 2 recorded boundaries (0.18.0, 0.19.0) ... Upgrade to 0.18.0 first
v0.19.0 -> v0.20.0 blocked reason=beyond-record-ceiling
... assess only as far as 0.19.0 ... Upgrade no further than 0.19.0
The verdict is right either way and it converges after two hops, so this is message quality only. The first one just points at 0.18.0 when 0.19.0 is the actual ceiling.

Thanks, this is the shape I was after.
One leftover from the move: the reason on this same step still reads "The new objects are untracked by Argo at this point; it neither prunes nor flags them." The claim does hold for Flux (mirror-created NodeWrights are not in the Kustomization's inventory, so prune: true will not reap them), but now that flux reads this group the sentence should name the reconciler generically, the way the description and rename-crs-in-one-commit reason already do.

--from old.yaml renders as v0.17.1 in the block above and v0.16.0 here, so the same file appears to hold two different versions.
Either rename this one (older.yaml) or use v0.17.1, which per the matcher also reports manual.

Not asking for a behavior change, but the doc comment on checkExpectedResources (around L232) now understates this path. It explains that gatedHealthCheckSuppressed returning directly discards whatever failures were already collected, and scopes that as a known gap on the grounds that the error is a Helm render or cancellation-induced.
This PR adds discovery (resolveNodewrightGVR) as a third error source on the same return. A transient non-NotFound discovery error, say an apiserver 503 while the loop happens to be on nodewright-customizations, now collapses the entire expected-resources report into a single ErrCodeInternal, which is precisely the "understates how much of the cluster went unchecked" outcome that comment exists to warn about. It is also a good deal likelier than a broken template.
Routing it through the failures accumulator can wait; naming discovery in the comment probably should not.

Escalating to request-changes on one item only: loneSubstantive returning false on found == 0.
matchVersions now reports blocked / multiple-boundaries for a jump that crosses only safe boundaries, which is the one outcome this branch was added to stop. Reproduced on this head with a synthetic two-safe record:
v1.0.0 -> v1.2.0 verdict=blocked reason=multiple-boundaries
crosses 2 recorded boundaries (1.1.0, 1.2.0); no single record describes the
whole jump. Upgrade to 1.1.0 first, then re-run this check
I am blocking rather than filing a follow-up because this is dormant, not visible. Nothing in the committed records triggers it today, the new tests do not cover the found == 0 case, and the failure mode when a second safe record lands is a blocked verdict telling an operator to stop at a version where nothing happens. That is the false-confidence direction ADR-021 cares about, and it is a one-line fix plus a control case while the code is open.
The other four comments in my previous review stand as nits: the "untracked by Argo" wording, the old.yaml version mismatch in the catalog examples, the beyond-record-ceiling vs multiple-boundaries message, and naming discovery in the checkExpectedResources doc comment. Take or leave any of them; none block.
Everything else here looks good, including the flux regrouping and the rdma-netns-exclusive retarget.
Withdrawing this approval: the all-safe crossing in loneSubstantive is a valid blocker that I dropped in my own pass, so this approval is stale against the current head.
….18.0 The deployment readiness gate polled skyhook.nvidia.com/v1alpha1 Skyhook and gated on a hardcoded skyhook.nvidia.com taint key. Operator v0.18.0 renames the kind to nodewright.nvidia.com/v1alpha1 NodeWright and writes completion status only there, and moves the default runtime-required taint key to nodewright.nvidia.com, so both reads missed and a tuned cluster timed out. Resolve the served group by discovery with a legacy fallback, and read the configured taint from the operator Deployment's RUNTIME_REQUIRED_TAINT rather than assuming a key -- --workload-gate is applied at bundle time and never reaches the recipe the validator is handed. Both fail closed. Restores the validator work from the closed PR #2597, which was live-validated on a bare-metal GB300 NVL72 but became unmergeable when the pin rolled back to v0.17.1, and carries the pin forward to v0.18.0 so its chainsaw assert on NodeWright is correct rather than premature. Beyond the validator, the legacy names leaked into surfaces #2597 never touched: - UAT gpu_census_verdict matched only the legacy taint prefix, so a node cordoned by v0.18.0 tuning reported "ok (N gpu-worker nodes ready)". A false pass, now covered by a test that fails without the fix. - tools/cleanup reaped no nodewright.nvidia.com CRDs, leaving them behind. - UAT debug capture dumped only the legacy kind, which is empty on v0.18.0. - Conformance assert-crds asserted the legacy CRD rather than the kind the operator writes status on. The pin bump reopens the transition record, as designed: its stale expect-aicr-readiness-to-fail steps are gone and the ceiling now sits on the pin. AICR's webhook.removalImage override is dropped because v0.18.0 qualifies the image upstream -- the BOM confirms an identical digest.

…a jump v0.19.0 moves only the operator image and adds an optional CRD field under templates/, so the boundary is safe: drain now completes when evicted pods have terminated rather than when their evictions were accepted, which changes when an interrupt begins but asks nothing of an operator on upgrade. Recording it exposed a matcher flaw. multiple-boundaries exists because composing two migrations is wrong -- an intermediate record's steps never run on a jump straight past it -- but it counted every crossed boundary regardless of verdict. A safe record carries no steps by construction, so crossing one composes nothing and skips nothing, yet a 0.16 -> 0.19 jump across the manual rename and the safe follow-up reported blocked and named v0.18.0 as somewhere to stop, when landing there changes no work. A crossed safe boundary no longer counts toward the skip rule when one substantive record describes the whole move, and the rename's to range now reaches through v0.19.0 to carry it. The reduction sits after the blocked checks, so an authored block still outranks everything, and two substantive boundaries still block. Both are pinned by the new test's control cases. Refs #2593 Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
An empty RUNTIME_REQUIRED_TAINT reported "is not a valid taint", which reads as though AICR cannot parse a value the operator accepted. It cannot: the operator's own options validation requires a runtime-required taint and refuses to start without one, so an empty value means the operator is not running. The chart renders the env unconditionally through quote, so empty is a shape that reaches this path rather than a hypothetical. A value supplied via valueFrom lands in the same branch and is now named as unresolvable rather than invalid, since the gate reads the Deployment spec. Both still fail closed. Also point the UAT census fixture at the operator's real default taint: the key is the bare nodewright.nvidia.com domain with runtime-required as the value, not a slash-suffixed key. Both shapes satisfy the prefix match, so the test passed either way and was not exercising what ships; reverting the phases.sh fix still fails it. readyDeployment loses its replicas parameter, which every caller passed as 1. Refs #2593 Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
The stale-taint cleanup probed the operator Deployment by app.kubernetes.io/name=nodewright. That label carries the CHART name, which was skyhook-operator until the chart was renamed at v0.17.0, so an operator installed from a pre-rename bundle is invisible to it. The empty result reads as a fresh deploy and the cleanup strips runtime-required taints out from under a live operator, uncordoning GPU nodes while tuning is still in progress -- exactly what the taint exists to prevent, on exactly the upgrade path this branch enables. The Deployment name is stable across both chart eras because the bundle pins fullnameOverride, so a second lookup by name catches what the label misses. It uses a field selector rather than a named get so an absent Deployment is an empty list rather than an error, and both queries keep the same shape. Either query failing still skips the cleanup rather than guessing the operator is gone. Covered by two cases in the taint-cleanup harness; both fail without the fix, the first by issuing the taint removal this prevents. Also correct four documentation claims: v0.18.0 is the rename boundary rather than the current pin, which is v0.19.0; the chainsaw health check is described as failing on a values-suppressed CR when the validator in fact suppresses the assert (gatedHealthCheckSuppressed, #1844); the record-blocks route omitted the case where a blocked record covers the source but is crossed alongside another boundary; and an editing slip had duplicated a comment in the transition record. Refs #2593 Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
…rator names recipes/checks/rdma-netns-exclusive/health-check.yaml still asserted status.status: complete on the legacy Skyhook. From v0.18.0 the mirror writes completion status only on the NodeWright, so on the pin this branch introduces the assert burns its whole 6m budget on a cluster whose tuning finished. Both VR200 overlays enable the component, so the path is live. Same defect already fixed for nodewright-customizations; this file was simply missed. runtimeRequiredTaints resolved the operator Deployment by the bundle-rendered name alone. The VR reference clusters install nodewright out of band with no fullnameOverride and render the chart's own name (#1828), where the lookup returned NotFound and the gate fell back to chart defaults -- waiting on taints that operator never applies while ignoring its live RUNTIME_REQUIRED_TAINT. Both supported names are now probed: exactly one wins, neither falls back as before, and both present fails closed with ErrCodeConflict, since picking one would gate on a value the other does not set. The transition record put flux in the helm group, whose steps say to sed the CR manifests and kubectl apply/delete them. Against a reconciler that drifts and is reverted on the next pass. Flux joins argocd in the git-sourced group, whose rename-in-one-commit sequence is what a reconciler actually needs, and the Argo-specific wording is generalized. Also correct the record header, which still called v0.18.0 the current pin. Refs #2593 Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
loneSubstantive returned false when every crossed boundary was safe, so the jump fell through to multiple-boundaries and reported blocked -- the one outcome the reduction was added to stop. If one safe boundary composes nothing and skips nothing, N of them compose nothing either: rule 4 forbids a safe record carrying steps, so there is no intermediate work a jump past it could miss. Dormant against today's records, which hold a single safe boundary, and it lands as a blocked verdict naming a stopping point where nothing happens the moment a second one is authored. This reverses TestMatchVerdictSelection/two_non-blocking_boundaries: it previously asserted that two crossed safe records block. Called out rather than quietly adjusted, because the case was named for the behavior it pinned. The ceiling check at the call site is what still stops this vouching past anyone's assessment. An intermediate attempt gated the reduction on the to ranges being contiguous, to keep that case blocking. It was wrong: exact-version to ranges are never contiguous, so it rejected the very shape the fix is for. Nits from the same round: the untracked-by-Argo reason now names the reconciler generically since flux reads that group, one catalog example showed two versions for the same old.yaml, and the checkExpectedResources doc comment now names discovery as the third error source on that early return -- an apiserver blip during nodewright-customizations collapses the whole report, which is likelier than the broken render the comment described.

…undaries The all-safe reduction skipped fromCovers, justified by a safe record carrying no steps. That answers the wrong question: fromCovers does not gate steps, it gates whether any record assessed the starting version, which is what undefined-origin is about. Conflating the two let the same origin be refused across one boundary and vouched for across two: 0.9.0 -> 1.1.0 blocked undefined-origin 0.9.0 -> 1.2.0 safe recorded Asking to go further bought the one verdict that vouches, which is the false-confidence direction, and it is the same dormant shape as the bug the previous commit closed rather than a different one. Reachable under the ADR's ordinary bounded-from idiom, since rule 3 starts coverage at the lowest floor rather than at zero. crossings orders by floor, so crossed[0] is the boundary that has to own the origin while top is the one that has to reach the target; both are now required. The doc comment no longer offers the steps argument for skipping an origin check. Two cases pin the pair, with bounded lower from ranges, which no existing fixture had. The nodewright records are unaffected: their crossing includes a manual, which goes through loneSubstantive and already checked fromCovers.

MAJOR: This new discovery call is not bound to ctx.Ctx. ServerResourcesForGroupVersion uses context.TODO() internally, and it runs before pollUntilStable; if API discovery stalls, deployment validation can outlive cancellation and the readiness budget instead of failing closed. The repository's context-aware DRA discovery path avoids this by issuing /apis/<group-version> through the discovery REST client.
Minimum correction: perform both group-version probes with the validator context and add a regression test where a blocked discovery request is canceled.
resolveNodewrightGVR probed both group-versions through DiscoveryInterface.ServerResourcesForGroupVersion, which issues its request with context.TODO() internally. It runs ahead of pollUntilStable, so a stalled apiserver would outlive cancellation and the readiness budget and hang until the Job is killed, rather than failing closed. The repository already had the cancelable form in allocmode for the DRA probe: the same GET through the discovery REST client, falling back to the interface method with a ctx.Err() recheck on either side for fake clients that expose no RESTClient. Rather than copy twenty subtle lines, that helper moves to validators/helper as GroupVersionResources and both callers use it. A context error now maps to ErrCodeTimeout rather than ErrCodeInternal, so a budget overrun reads as one. Discovery failures also name the signal, matching how the rest of this report identifies it, since they are now one of the ways the nodewright probe can fail. The regression test asserts a canceled context surfaces instead of a verdict; against the previous call it returns nil and a served group.

Re-approving after pushing the catch-up merge to current main (includes #2849).
The compile failure at expected_resources.go:1174 was a semantic merge conflict with #2847, not a defect in this PR: the dra-node-labeler case merged in from main still passed the goCtx parameter that this branch's refactor to *validators.Context removed. Now passes ctx.Ctx, matching the gcp-driver-installer case above it.
stock_render_golden.yaml was regenerated rather than hand-resolved — the merge produced 55 checksum conflicts because #2849 changed the CRD-step script while this branch bumps the nodewright pin, so the golden now reflects both.
Verified locally: go build ./validators/..., go test ./validators/deployment/..., and the render-parity and BOM-versions tests all pass.
The examples pinned v0.17.1 while the registry moved to v0.19.0 in #2829, and this branch then changed their namespace, leaving a fresh namespace beside a stale pin. A v0.17.1 operator ships only the legacy Skyhook CRD, so an example carrying the renamed NodeWright CRs could not apply. Every other pin in these files already matches the registry; only nodewright-operator had drifted. Caught in review by CodeRabbit. Signed-off-by: Brian Lockwood <lockwobr@gmail.com>

Summary
Resolve the nodewright API group by discovery instead of assuming
Skyhook, read the runtime-required taint from the operator Deployment instead of hardcoding its key, and carry the pin forward tov0.19.0.Motivation / Context
The deployment readiness gate polled
skyhook.nvidia.com/v1alpha1 Skyhookand gated on a hardcodedskyhook.nvidia.comtaint key. Operatorv0.18.0renames the kind tonodewright.nvidia.com/v1alpha1 NodeWrightand writes completion status only there, and moves the default runtime-required taint key tonodewright.nvidia.com— so both reads missed and a fully tuned cluster timed out after the 8m poll budget.This restores the validator work from #2597, which was live-validated end to end on a bare-metal GB300 NVL72 (deployment 4/4, conformance 5/5, performance 1/1) but became unmergeable when the pin rolled back to
v0.17.1in #2633: its chainsaw assert onNodeWrightwas correct only for av0.18.0+ pin. Moving the pin forward is what makes it correct again.Fixes: #2593

Rollout notes: This moves the pinned operator two minors, so bundles change. The validator reads either API group, so clusters on
v0.17.xkeep working through the fallback. Rebased ontomainafter #2772 landed; both goldens and the BOM were regenerated against the merged tree.Two things deliberately not done:
kind: SkyhookCRs undernodewright-customizationsandrdma-netns-exclusiveare unchanged. The operator mirrors them, sov0.18.0/v0.19.0work — but they must be renamed beforev0.20.0removes the group. That is nodewright v0.18.0 upgrade changed the CR status contract (Skyhook -> NodeWright); legacy status never populates #2594, and fix(validator): read NodeWright CR and configured runtime-required taint #2597 scoped it out for the same reason.skyhook_controller.go: "Remove every recognised runtime-required taint, not just the configured one"), so it converges. Re-keying live cluster provisioning is not something that can be validated locally.One follow-up worth filing: AICR's tuning CRs declare interrupts and set no
