On the same nvkind cluster pre-#2346, the gate took the other branch and passed: One note for whoever picks up the fix. #2346's stated reason for letting node-label presence take priority over the DaemonSet lookup was that an exact-name match fails open on OpenShift, where the DaemonSet is named Re-running will not help — this is deterministic gate logic rather than flake.

MINOR: readWorkloadClosure decodes only images, so a mismatched sourceVersion, an absent nvcre file, or an empty list all pass, and nvcre-closure-check runs in no gate. A manual nvcre defaultVersion bump followed by make bom-docs passes every check while container-images.md and the CycloneDX BOM list the v0.2.0 workload images under the new version, contrary to the "cannot quietly describe a version AICR no longer ships" claim in main.go#L72-L74.
Minimum correction: fail here, offline, when nvcre's closure is absent, empty, or its sourceVersion differs from pinnedVersion(c), with a test for each case.
There was a problem hiding this comment.
Confirmed, and worse than stale data alone — fixed in 4a43c55.
You were right on all three counts. workloadClosure decoded only images, so sourceVersion, platform, and gpuArchitecture were written and never read. readWorkloadClosure returned nil, nil on os.IsNotExist, making an absent closure indistinguishable from a component that legitimately has none. And nvcre-closure-check appears in no workflow — I grepped all of .github/ and got nothing, so your "runs in no gate" was exact.
The fix follows your "fail here, offline" framing rather than wiring a new CI job, which I think was the better half of the suggestion: the check now lives inside the survey, so make bom-docs and the committed-BOM test gate it transitively and there is no workflow to forget. Three conditions now fail the survey:
sourceVersionnot equal topinnedVersion(c)— including absent, since a closure that declares no version cannot vouch for the one it was generated from.- an absent closure for a component in
closureRequiredComponents(nvcre today), while staying optional for everyone else as you asked. - a required closure that lists no images.
TestReadWorkloadClosureFailsClosed covers all six cases. The scenario you described — bump defaultVersion, run make bom-docs, everything green while the BOM lists v0.2.0 images under the new pin — is the "sourceVersion behind the pinned chart version" subtest.
Worth noting this is the same defect class as your MINOR on #2808, where a defaultVersion bump could leave the controller digest behind. Both were a version pin that could move while a digest-bearing artifact stayed put. That one landed in 3c4745e.

Ships default quota CRs (ResourceFlavor `default-flavor`, ClusterQueue `cluster-queue`, LocalQueue `default` in the `default` namespace) so admission works out of the box — tune the ClusterQueue's nominal quotas to cluster capacity to enact real limits. Managed frameworks are pinned to batch/job, JobSet, and TrainJob. Upgrade note: the quota CRs are helm post-install/post-upgrade hooks with a delete-and-recreate policy — quiesce queues before upgrading the bundle (Kueue's resource-in-use finalizer on an active ClusterQueue/ResourceFlavor blocks the delete and can wedge the upgrade), and re-apply tuned quotas afterwards since upgrades reset them to the shipped defaults. Uninstalling leaves the hook-created CRs behind; delete them manually when removing Kueue. Overlays that override the component's `manifestFiles` (replacing the default quota CRs) must also override its health check — the shipped check asserts the default CR names above.

MINOR: This tells every disconnected install to mirror workload-images.yaml, but that set covers only aws/h100 and two entries, and make nvcre-closure cannot regenerate any other scope. A GKE H100 NCCL or training run also pulls tcpgpudmarxd-dev:v1.0.8 (gcp-h100-tcpxo-runtime-patch.yaml#L43), which is absent from the set, so an air-gapped run fails with ImagePullBackOff.
Minimum correction: state the covered platform, architecture and entries here, and show the -platform/-arch/-entries/-out invocation for other paths.
There was a problem hiding this comment.
Right, and fixed in e6e988d. The note told every disconnected install to mirror a set that resolves the catalog for platform: aws, gpuArchitecture: h100, and two entries, without saying so anywhere.
While verifying I found a sharper piece of evidence than the tcpgpudmarxd-dev example: the committed NCCL image is public.ecr.aws/hpc-cloud/nccl-tests:cuda12.8.1-efa1.43.2-..., an EFA build. So it is not that the AWS set is missing a GKE image or two — the NCCL image itself does not apply off AWS. I used that in the doc because it makes the scoping self-evident rather than a caveat the reader has to take on faith.
The note now names the platform, architecture, and both entries, says mirroring this set leaves another platform's images unmirrored, and shows the invocation with -out pointed away from the committed path so deriving another scope does not clobber the gated file.

| #### Both supply-chain gaps close at the shipped pin |
There was a problem hiding this comment.
MINOR: Gap 2 and the gate at L209 require a chart SBOM, which follow-up 2 says is still absent, yet this heading says both gaps close and follow-up 2 is struck through in full. Follow-up 6 ("once items 1–5 close") then reads as satisfied, misstating the supply-chain gate for v0.2.0.
Minimum correction: mark gap 2 partly closed (signature and provenance present, chart SBOM missing) and keep follow-up 2 open for the SBOM.
There was a problem hiding this comment.
Agreed, fixed in e7fe75e. The heading claimed both gaps closed while the prose under follow-up 2 already said the chart SBOM was absent, so the document contradicted itself and the full strikethrough resolved the contradiction the wrong way.
Three corrections:
- Heading is now "Gap 1 closes at the shipped pin and gap 2 partly". No inbound anchors to the old slug — I grepped before renaming.
- Added a short paragraph after the SBOM detail, stating that the L209 gate asks for signature, SBOM, and provenance on both artifacts, that the chart has the first and third only, and that the gate therefore does not pass.
- Follow-up 2 now reads "Upstream: publish a chart SBOM" live, with only the signing-and-provenance half struck through, and says explicitly that item 6 is not reached.
That last part was the real cost you identified: item 6 is gated on "items 1–5 close", so striking 2 through in full made the ADR look two items from done when it is not.

…estations NVCRE's workload catalog is go:embed-compiled into the manager binary, so the images the certification benchmarks run never appear in rendered chart output and AICR's mirror discovery cannot see them. ADR-025 makes closing that gap a benchmark execution safety gate that binds before any opt-in validator ships. Add tools/nvcre-closure. It derives the closure from the upstream catalog at the registry's pinned chart version, resolving the `when:` selectors so only the supported aws-h100 certification paths are inventoried, then digest-resolves every image and records runtime fetches. The BOM consumes the generated file, so nvcre reports four digest-pinned images rather than the one the chart renders. Defaulting the version to the registry pin is what makes the obligation self-renewing: a `defaultVersion` bump re-derives against the new catalog and fails `make nvcre-closure-check` until the closure is regenerated, so the inventory cannot quietly describe a version AICR no longer ships. Two findings are recorded rather than fixed. The training path clones Megatron-LM at pod start, so it cannot run disconnected at all regardless of digest pinning; the NCCL path can. And the `:latest` tag ADR-025 flagged still exists at v0.2.0, but only behind GB300 RoCE selectors, so it is off the supported path — a unit test pins that distinction by resolving the same entry for both accelerators. Verifying the attestations at the shipped pin closes two upstream asks ADR-025 recorded as open at v0.1.0: image and chart both carry a cosign signature and SLSA v1.0 provenance that verify against the release workflow identity, and the chart attestations bind the chart digest. A chart SBOM is still absent. Note that `cosign verify-attestation --type slsaprovenance` reports no match on this pin because that shorthand means SLSA v0.2; the predicate is v1.0. Signed-off-by: Rohit Rajani <rorajani@nvidia.com>
The closure records sourceVersion and the BOM survey never read it back, so a chart bump landing before the closure was regenerated republished the previous version's workload images under the new pin. An absent or empty file was also indistinguishable from a component that has no closure, which narrowed the BOM with no error. Decode sourceVersion and require it to name the registry pin, and treat an absent or empty closure as a defect for the components whose inventory is part of the BOM contract. The check is offline and inside the survey, so make bom-docs and the committed-BOM test gate it without a workflow of its own. Signed-off-by: Rohit Rajani <rorajani@nvidia.com>
The single pattern required -b or --branch ahead of the URL, so 'git clone <url> <dir>' and 'git clone <url> -b <ref>' matched nothing and recorded no runtime fetch. The closure then implied the path could run from a mirrored registry alone. Match the clone command, then read the URL and the optional ref from it separately. Signed-off-by: Rohit Rajani <rorajani@nvidia.com>
Entries were trimmed inside the resolution loop, so the scope written to the closure kept the raw flag value: -entries "a, b," recorded " b" and "", and the leading space reordered the sorted list. Signed-off-by: Rohit Rajani <rorajani@nvidia.com>
The disconnected-install note told every install to mirror the committed set, which resolves the catalog for aws/h100 and two entries only.

The heading claimed both supply-chain gaps closed at the shipped pin and struck follow-up 2 through in full, while the prose beneath it says the chart SBOM is absent.

Found while testing the closure against NVCRE v0.6.0, which moved the Megatron-LM remote out of the clone command and into a shell variable assigned from an overridable template. The scanner found no literal URL and dropped the fetch, so the derived closure recorded no runtime fetch at all and read as air-gap clean on a path that still clones at pod start. Follow a variable reference to its assignment and read the remote from there. A clone whose remote still cannot be resolved is now an error rather than an omission: a dropped clone does not make the closure smaller, it makes it answer the one question it exists for incorrectly. Signed-off-by: Rohit Rajani <rorajani@nvidia.com>
v0.2.0 was four minor releases behind. The move is additive in schema and values, and it picks up an EFA regression fix that matters on the shipped AWS paths: two override paths matched platform aws with no GPU guard, so every AWS architecture stripped /opt/amazon and unset NCCL_NET_PLUGIN before the workload ran, leaving EFA devices attached and unused while NCCL fell back to TCP over eth0. Evidence gathered for the pin: all seven CRDs keep a single v1alpha1 version that is both served and storage, so nothing needs conversion; the CRD diff adds 624 lines and removes 10, all of which are nodeNames description prose; chart values gain only a disabled-by-default pdb block and ServiceMonitor scrape knobs; chart and controller index both verify against the release workflow identity at refs/tags/v0.6.0, with the chart SBOM still absent as at v0.2.0; and the workload closure re-derives to the same three images at the same digests. What does change is where v0.6.0's behavior lives. It adds CEL transition rules making four Job and Workflow fields immutable in presence as well as value, so on an ownsCRDs component a deployer that leaves the old CRDs in place finishes the upgrade with none of the new admission behavior present. That is what the new transition record is for, and why its verdict is manual rather than safe. Signed-off-by: Rohit Rajani <rorajani@nvidia.com>
TestOwnsCRDsPinsMatchAuditedVersions caught the v0.6.0 bump, which is what it is for: a version bump does not carry the CRD-ownership audit forward. Re-ran the procedure documented beside the pin. The chart ships the same seven CRDs as the audited v0.2.0, all in the vendor-specific nvcre.nvidia.com group, and no other registry component references that group in crds/ or templates/. Neither version declares a conversion block at all, so spec.conversion.strategy: Webhook is absent rather than merely unset. Both properties ownsCRDs asserts therefore still hold. Signed-off-by: Rohit Rajani <rorajani@nvidia.com>
…ignments Two defects in the resolver added a commit ago, both found in review. git accepts an https remote with no .git suffix, which the pattern required. Combined with failing closed on an unresolvable remote, that turned a valid suffixless clone into a halt rather than a recorded fetch. A fallback pattern now takes the whole token, tried after the .git form because the remote is often followed by template syntax with no separator that a token-greedy match would swallow. Assignments were also collected from the whole block rather than the text before each clone, so a block that reassigns the remote between two clones gave both the last value. The earlier repository then dropped out of the closure silently, because dedupeFetches collapsed the resulting duplicate. The committed closure re-derives byte-identically.

There was a problem hiding this comment.
False positive — no out-of-bounds read is reachable here, so I am not pushing a change for it. The PR is approved with auto-merge armed and 89 checks green; dismissing that to silence a static-analysis pattern match would cost more than it buys.
The loop bound i <= len(lines) is deliberate. i == len(lines) is a sentinel iteration that flushes the final override block, which otherwise has no - line after it to trigger the flush. On that iteration nothing indexes lines:
- Line 136 is
isItem := i < len(lines) && strings.HasPrefix(lines[i], "- "). Go&&short-circuits, solines[i]is not evaluated wheni == len(lines). That is a language guarantee, not a convention. - Line 139 is
lines[start:i], a slice expression. For a slice,0 <= low <= high <= len(s)is valid, soi == len(lines)is in range by definition.startis only read whenstart != -1and is always<= i.
There is no other access to lines in the loop body. The checker appears to be matching i <= len(x) as a bound without modeling the short-circuit guard on the next line.
It is also exercised rather than merely argued: every entry with an overrides: section reaches the sentinel iteration, since that is the only path that emits the last block. catalog.go is at 97.5% statement coverage and the suite runs under -race.
If the pattern is worth not re-triggering, the structural fix is to drop the sentinel and flush after the loop rather than inside it. That is a readability change with no behavior difference, so it belongs in #3129 with the other nvcre-closure follow-ups rather than in a commit that dismisses an approval.

Summary
Derives the NVCRE workload runtime closure — the certification benchmark images that rendering the chart cannot reveal — digest-resolves them, and feeds them to the BOM. Also verifies the v0.2.0 attestations against the shipped pin.
Motivation / Context
NVCRE's workload catalog is
go:embed-compiled into the manager binary, so the images the benchmarks actually run never appear in rendered chart output. AICR's mirror discovery extracts images from rendered YAML, so it reported one controller image and looked complete while missing everything behind it. ADR-025 makes closing that gap a benchmark execution safety gate, and the epic is explicit that this one does gate everything, because it is an artifact-safety precondition rather than a capability outcome.Stacked on #2808. Base is
feat/nvcre-digest-pin, notmain— both PRs touchregistry.yaml,values.yaml, the BOM doc and the nvcre test, and #2808 carries the digest pin this builds on. GitHub retargets tomainautomatically when #2808 merges.Related: #2684

The closure is small, and that is the finding. On the two supported paths at
aws-h100it is three images and one runtime fetch:nvcr.io/nvidia/pytorch:26.01-py3sha256:38ed2ecb…1007envcr.io/nvidia/pytorch:25.08-py3sha256:ace9a848…c50fbpublic.ecr.aws/hpc-cloud/nccl-tests:cuda12.8.1-…-testsv2.16.9sha256:6cabd2c0…3bfe2Derived, not transcribed.
tools/nvcre-closurereads the catalog from the upstream repository at the tag matching the pinned chart version, evaluates thewhen:selectors, follows{{ lib }}fragment references, and digest-resolves each image. The catalog entries are Go templates, not YAML —{{ lib "…" }}sits where a mapping key is expected — so the scan is block-wise rather than a document walk.The staleness check is self-renewing, and now actually gated. With no
-version, the tool reads the registry'sdefaultVersion, so a chart bump re-derives against the new catalog and failsmake nvcre-closure-checkuntil the closure is regenerated.nvcre-closure-checkis deliberately not wired intomake lintormake qualifybecause it clones upstream and resolves digests — the same reasoning that keepscheck-settings-checksumsout.As first pushed, that left the "cannot quietly describe a version AICR no longer ships" claim resting on a check no gate ran, which @mchmarny caught. The BOM survey now re-reads
sourceVersionand rejects a closure that does not name the registry pin. That check is offline, somake bom-docsand the committed-BOM test enforce it transitively and there is no new workflow to forget. See the review follow-up below.Two findings recorded rather than fixed:
git clone --depth 1 -b core_v0.15.2 https://github.com/NVIDIA/Megatron-LM.gitat pod start. That is better than a floating branch but still a tag, and a clone at pod start is a hard air-gap blocker regardless of digest pinning. The NCCL path has no runtime fetch and can run disconnected.:latestpin ADR-025 flagged still exists at v0.2.0, in five places, but every one is behind agpuArchitecture: equals gb300selector or the GB300 RoCE dep, so none is reachable onaws-h100.Attestations at the shipped pin close one upstream ask and most of a second. Both image and chart carry a cosign signature and SLSA v1.0 provenance, verifying against
…/attest.yml@refs/tags/v0.2.0; chart attestations bind the chart digest, confirmed by runningcosign treeagainst the digest rather than the tag. A chart SBOM is still absent — the CycloneDX attestation covers the image's per-platform children only. One trap worth knowing:cosign verify-attestation --type slsaprovenancereports no match on this pin, because that shorthand means SLSA v0.2 and the predicate here is v1.0; useslsaprovenance1.NVCRE moves from v0.2.0 to v0.6.0 (
0d2a9f781). v0.2.0 was four minors behind. Evidence for the pin, all gathered offline except the attestation checks:v1alpha1, served and storage — no conversion, no storage boundarynodeNamesdescription proseJoband 5 onWorkflowpdbblock defaulting to disabled, plus ServiceMonitor scrape knobssha256:af20cf1d…and controllersha256:8008c6f9…both verify againstattest.yml@refs/tags/v0.6.0; chart SBOM still absent, as at v0.2.0_gbps→_gbs)The bump also picks up an EFA regression fix that matters on the shipped AWS paths: two override paths matched
platform: awswith no GPU guard, so every AWS architecture stripped/opt/amazonand unsetNCCL_NET_PLUGINbefore the workload ran, leaving EFA devices attached and unused while NCCL fell back to TCP overeth0.What actually needs operator attention is where v0.6.0's behavior lives. It adds CEL transition rules making
nodeHealthMonitor,goodputMeasurement,bandwidthMeasurement, andworkloadMetadataimmutable in presence as well as value onJobandWorkflow. On anownsCRDscomponent, a deployer that leaves the v0.2.0 CRDs in place finishes the upgrade with the controller on v0.6.0 and none of the new admission rules present — deployed, Ready, and not actually upgraded. Since the API version and its served/storage flags are identical in both charts, neither release status norstoredVersionsdistinguishes the two states; only the rule text does. That is what the newrecipes/components/nvcre/upgrades.yamlrecord is for, and why its verdict ismanual. Two of the upstream breaking changes (honorLabels: trueby default, the gauge rename) are inert here because AICR shipsmetrics.serviceMonitor.enabled: false.Worth noting the release notes undersold the change twice: they name three immutable fields where the CRDs carry four, and they do not mention
Workflowat all.Review follow-up (six commits after the first round). @mchmarny and CodeRabbit independently found the same hole from three angles, and it was the load-bearing one:
4a43c5548— the BOM survey decoded onlyimages, sosourceVersionwas written and never read back, and an absent or empty closure returnednil, niland was indistinguishable from a component that has none. AdefaultVersionbump followed bymake bom-docspassed every check while the BOM listed the old version's workload images under the new pin. The survey now requiressourceVersionto name the registry pin (absent counts as a mismatch) and treats an absent or empty closure as a defect for nvcre while staying optional elsewhere. This is the same defect class as @mchmarny's MINOR on fix(recipes): pin nvcre image by digest and guard opt-in wiring #2808 — a version pin free to move while a digest-bearing artifact stays put.c0ff5f5d0—gitClonePatternrequired-b/--branchahead of the URL, sogit clone <url> <dir>andgit clone <url> -b <ref>recorded no runtime fetch at all and the closure implied the path could run from a mirrored registry alone. Verified as a real regression test by reverting the regex: three of four spellings fail without the fix.747c85e02— entries were trimmed inside the resolution loop, so-entries "a, b,"wrote" b"and""into the committed closure and the leading space reordered it.e6e988d5d— the disconnected-install note told every install to mirror a set scoped toaws/h100and two entries. The committed NCCL image is an EFA build, so it does not apply off AWS at all; the note now names the scope and shows how to derive another.e7fe75e45— ADR-025's heading claimed both supply-chain gaps closed while the prose beneath said the chart SBOM was absent, and follow-up 2 was struck through in full. Since item 6 is gated on "items 1–5 close", that made the ADR read two items from done. Gap 2 is now marked partly closed and follow-up 2 is open.ec93ab74f— found by testing the closure against v0.6.0, which moved the Megatron-LM remote out of the clone command into a shell variable assigned from an overridable template. The scanner found no literal URL and dropped the fetch, so the derived closure recorded no runtime fetch at all and read as air-gap clean on a path that still clones at pod start. Variable references are now followed to their assignment, and a clone whose remote cannot be resolved is an error rather than an omission. Only the template default is ever recorded — the scan reads catalog templates, never a rendered object, so an operator'ssourceRepooverride cannot reach the committed closure, which matters because upstream documents that the override may carry credentials in the URL.Testing
