docs(evidence): VR200 NVKE inference-dynamo and training-kubeflow - #3720
Adds signed recipe evidence for vr200-nvke-ubuntu-inference-dynamo and vr200-nvke-ubuntu-training-kubeflow. It also adds their entries in the embedded evidence index and a community allowlist entry for the signer. Both recipes were validated on an NVKE VR200 tenant cluster: training with AICR main d2db93111, and inference with main 0cf4a6543, which includes #3715.
Motivation / Context
This is the first signed recipe evidence for VR200 on NVKE. The VR200 NVKE CNCF AI conformance submissions (#3621 training, #3695 inference) carry behavioral evidence, but no signed AICR attestation.
Other: recipe evidence pointers (recipes/evidence/) and the evidence index (pkg/evidence/index/pointers.yaml)
Implementation Notes
Cluster.
NVKE tenant cluster on Kubernetes v1.36.3.
2x VR200 trays with 4 GPUs each, in one NVLink domain.
Ubuntu 26.04, kernel 7.0.0-2022-nvidia-bos-64k.
Deployment.
Each recipe was deployed from scratch from its own bundle.
Both bundles were built with --accelerated-node-selector nvidia.com/gpu.deploy.driver=true. This keeps the DRA kubelet plugin off the GPU-less control plane.
The inference bundle was also built with --set agentgateway:serviceType=ClusterIP, because the tenant has no LoadBalancer. docs/integrator/nvke-vr200-setup.md prescribes this.
Validation used aicr validate --phase all --emit-attestation, with validator images pinned to the :sha- tag of the commit each run used.
Training performance: nccl-all-reduce-bw-nvls passed at 1044.01 GB/s; the floor is 600.
nccl-all-reduce-bw-net was withheld with --skip-check, and the bundle records it as skipped (named-in-skip-checks). The overlay prescribes this: these trays' DPUs do not bridge the spare ConnectX-9 ports, so the cluster has no east-west NIC path.
Signing.
The bundles are in ghcr.io/xdu31/aicr-evidence, which is public.
They were signed by the fork's evidence-publish.yaml on refs/heads/evidence/nvke, with Rekor entries 190504413 (inference) and 189860404 (training).
The new community allowlist source is c0e6951cd501b85118706a01b76f2bb5, labeled xdu31.
Trusted registry. A repo admin added ghcr.io/xdu31 to EVIDENCE_TRUSTED_REGISTRIES, so ingest can count this evidence on validation.aicr.run.
Testing
go run ./tools/evidence-pointercheck -root recipes/evidence # OK: all committed pointers honor the per-source contract
go test ./pkg/evidence/... -count=1 # 10 packages ok
make qualify was not run. The change is data only, and the targeted evidence checks above cover it.
Risk Assessment
Low: data only. It adds two pointers, one allowlist entry, and the regenerated index.
Medium: Touches multiple components or has broader impact.
High: Breaking change, affects critical paths, or complex rollout.
Rollout notes: N/A
Checklist
Tests pass locally (make test with -race). Only the evidence packages were run, as above.
Linter passes (make lint). It was not run, because the change is data only.
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
Changes follow existing patterns in the codebase
Commits are signed off and cryptographically signed (git commit -s -S). The signing commit is GitHub-signed by the workflow.
Unsigned flat pointers for vr200-nvke-ubuntu-inference-dynamo and vr200-nvke-ubuntu-training-kubeflow. The bundles are in ghcr.io/xdu31/aicr-evidence, validated on aicr d2db931. The training run withholds nccl-all-reduce-bw-net: this cluster has no east-west NIC path, as the overlay notes. The fork's Recipe Evidence: Sign workflow signs them on push.

Trigger review
Walkthrough
The change adds a community signer to the allowlist, attestation records for the VR200 inference and training recipes, and evidence index entries that reference their shared source slug.
NVIDIA/aicr issue 3155 — The inference attestation records a bundle digest, which relates to the issue’s objective of keeping evidence digests current.
Suggested reviewers:njhensley, mchmarny
Merge Risk: Moderate · previous review 6336f
The new VR200 evidence will not reach the dashboard, and the push-triggered ingest job will fail, until the registry is added to the trusted-registry repository variable. Update that variable before or together with the merge.
Security architecture risk: Low · up to 6336f
The change adds one trusted publishing identity without weakening the existing signature or publication safeguards. Its authorization can apply beyond the two added recipes. The publisher’s registry approval and referenced signed bundles were not independently confirmed.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — Control of the allowlisted evidence-publish workflow identity on xdu31/aicr’s evidence/nvke branch can authorize community evidence contributions. The allowlist is signer-scoped, not recipe-scoped, so future admitted evidence from that identity could affect other recipes’ corroboration. The present index contains only the two VR200 additions; no deployment or cloud-credential authority is granted by this entry.
Trust Boundaries and Controls
observed — The structural pointer-tree check classifies claimed signer fields without cryptographically verifying the bundle. That is not the publication authority: authoritative ingestion pins verification to the claimed issuer and exact identity, derives actual signer claims from the verified certificate, and rejects mismatches before synthesis.
Resilience and Maintainability Implications
observed — Invalid, incomplete, canceled, or unknown verification verdicts are rejected before synthesis. Same-reference workflow runs are serialized without canceling an in-progress run, and failed pointer batches cannot reach the credentialed publication job. These existing controls are unchanged by the new signer and records.

The inference-dynamo pointer was attested at d2db931, before NVIDIA#3715
changed the agentgateway component, so its recipe digest no longer
matched main. Validation was re-run at 0cf4a65 with the bundle built
with --set agentgateway:serviceType=ClusterIP, as the NVKE VR200 guide
prescribes for a tenant with no LoadBalancer: deployment 4/4,
conformance 10/10. The recipe digest is now 5b28f5668b07.
This replaces the stale pointer with the new unsigned one. The fork's
evidence-publish workflow signs it and relocates it under the same
source, so the allowlist and the index are unchanged.

Sign and relocate the inference pointer.
This pointer is unsigned and remains at the evidence root. The pointer check rejects it, and TestPointersYAMLMatchesTree fails. If merged, ingest also skips it because it has no signer. (raw.githubusercontent.com)

Trust the bundle registry before merging.
The PR states that ghcr.io/xdu31 is not in EVIDENCE_TRUSTED_REGISTRIES. The push-triggered ingest will therefore reject this pointer and fail the job, so the evidence will not reach the dashboard. Add the required registry prefix before merge, while preserving the existing trusted prefixes. (raw.githubusercontent.com)
