Reviewed the detection, the overlays, and the rendered output. Detection and the overlays are correct: compared with GCP G4, the Akamai render differs only in NCCL_P2P_LEVEL (PHB instead of SYS) and the missing nvidia.com/gpu toleration. LKE nodes of other architectures lose nothing by moving from onprem to akamai, because the onprem overrides and NIC detection only cover gb200, gb300, b200 and b300. pkg/catalog, pkg/platform, pkg/controller, pkg/certification, pkg/render, pkg/workloadrun and the workloadrun integration cases pass locally.
The CodeRabbit finding on akamai_test.go:34 can be dismissed. Go 1.27 accepts promoted fields in composite literals, pkg/controller/event_helpers_test.go:87 already uses Certification{Name: ...}, and the test compiles and passes.
Inline comments cover the default test size and the P2P level. Three more items are outside the diff:
- ADR. Every earlier platform onboarding has one (Mistral ADR-058, Azure ADR-060, Nscale ADR-085, OCI ADR-088), and the development workflow in AGENTS.md requires one for a change like this. It would also be the natural home for the P2P and test-size decisions below.
- CLI reference. The
--platformvalue lists indocs/cli-reference/certification.md:93anddocs/cli-reference/workloadrun.md:72don't includeakamai. gpu-defaults.yaml:56. Thertxpro6000comment still describes only G4 shapes ("G4 supports multiple sizes"), but that default now applies to Akamai too.
The workflow render --platform akamai gap is filed separately as #538.

ADR-101 is taken by NVIDIA#510, NVIDIA#533 and NVIDIA#537, and 102 by NVIDIA#539. Build on NVIDIA#510's networkAttachments rather than deferring an override field: detection runs only when the resolved options set no list, and the failure messages name the list as the fix. From review: - A single match in the workload namespace wins outright; the equivalence rule applies only to candidates elsewhere, so a site under namespaceIsolation can add its own NAD. State that the workload namespace is the Certification's. - Only zero matches, differing matches, Forbidden and NoMatch are terminal. Other list errors requeue through retryableCreateError. - No default in the catalog loader: every caller sets the name, and Build fails when it is empty with NICs requested. - --dry-run warns on Forbidden, since it lists with the user's kubeconfig rather than the controller's service account. - Name networkAttachments and rdmaDeviceAccess: hostPath in the zero-match message, say that an empty spec.config is never equivalent, and hint at deleting a hand-made sriov-net copy. - Correct the globalNamespaces note: default is implicit only while globalNamespaces is unset. - List every place that names sriov-net as fact, and clarify the wrong-key test case.

This looks good to me. The Akamai registration, the linode:// detection and the TCP overlays hang together, and I like that the bounded NCCL sizes are documented as something the user sets explicitly rather than quietly changing the generic defaults.
One thing to pick up: README.md:15 still reads "Platform detection (AWS, GCP, Azure, OCI, nscale, TogetherAI, Mistral, Forge, on-prem)" with no Akamai. You updated docs/cli-reference/certification.md:93, docs/cli-reference/workloadrun.md:72 and the render-platform-flag/unknown-platform golden, so that README line is the odd one out on the front page. Worth adding Akamai there.

Review follow-ups for NVIDIA#510 (ndipebot). Ordering: a WorkloadRun's platform overrides are not applied when the Workflow spec is built. They travel in spec.overrides and the Workflow controller applies them later, replacing scalars, so Azure's nvidia.com/mlnxnics: 8 replaced 8 plus one networkAttachments entry and the run asked for 8. The new platform.ApplyNetworkAttachmentsToOverrides raises every platform override patch that already requests one of the listed resources by the same count, and writes the networks annotation into any patch that sets one. It runs after BuildOverrides in both the controller and BuildWorkflowSpec, together with the runtime write that moves there too. Azure H100 plus one mlnxnics entry now requests 9 on workloadrun render, the WorkloadRun controller and certification render. The user's spec.overrides are appended untouched and still win. Tests: - render-network-attachments (azure, togetherai), workloadrun-network-attachments/azure-h100-same-resource-adds and certification-render-network-attachments/azure-h100-same-resource-adds pin the 9, plus TestApplyNetworkAttachmentsToOverrides. - read-workloadrun error cases: upper-case network, a kubernetes.io/ resource, 17 entries, an empty list, and a list with nicResourceName. - reconcile/certification-network-attachments-merged-hostpath: a category list merged with a spec-level rdmaDeviceAccess: hostPath fails the whole Certification with WorkflowValidationFailed and creates no Workflow. - TestNewRunCommandValidation: --cert-file with --network-attachments, --multus-networks, --extended-resources, and the pair. - certification-render-network-attachments/onprem-b300-skips-nic-detection and TestApplyWRNICDetection pin the NIC-detection skip for an explicit list. The WorkloadRun dry-run gate moves into applyWRNICDetection. ADR-104 Decision 3 now says a conflict fails the whole Certification, and Decision 6 describes the override handling. The #TBD placeholders are gone. Two goldens from this PR are refreshed for main: the build-workflow-spec mpi-network-attachments override count (Akamai's override from NVIDIA#537) and the certification-onprem-b300-multirail worker sshd script (NVIDIA#528).

…tion goldens The render annotation goldens pinned each applied override's index, which is its position in the catalog entry's overrides list. Inserting any block above it in pkg/catalog/entries/communication/nccl-all-reduce.yaml shifts the ordinal, so the goldens broke without any change to this code: after main brought in NVIDIA#537's Akamai block, nscale-gpu-arch-flag wanted 18 and got 19, failing Test on the PR head. The projection now records only when, patches and noOp, which still identify the blocks that matched. The four affected goldens change only by losing their index lines. The docs also said an offline render without --platform detects onprem. That holds for a plain nodeSelector, but syntheticRenderNode copies the whole selector onto the synthetic node, so a Forge marker (nke.nvidia.com/site-name, or a hostname containing forge) detects as forge instead, and --platform onprem does not change it because its synthetic providerID is empty. That precedence predates this change. The sentence is hedged in docs/cli-reference/certification.md, docs/concepts/platform-detection.md, CLAUDE.md/AGENTS.md and the resolveWorkflowsOffline comment; matching behaviour is unchanged.

* docs: link ADRs by GitHub URL so they resolve on the docs site docs/designs/ is not in the Fern nav (ADR-074 and ADR-088 both record that), so a relative link such as ../designs/092-....md renders as a link to Fern's "Page Not Found" page, which answers HTTP 200. Eighteen such links across thirteen pages broke this way at v0.8.0. #256 already moved the first-certification and goodput ADR links to GitHub URLs for the same reason; this does the same for the rest. Neither `fern check` nor `fern docs broken-links` notices: the latter passes on the unfixed pages. TestPublishedPagesLinkOnlyToPublishedPages in test/docspolicy now requires every relative link on a page in docs/index.yml to resolve to another page in the nav, and every github.com/NVIDIA/cluster-readiness-engine/{blob,tree}/main link to name a path that exists, so a typo cannot trade the soft 404 for a hard one. TestBrokenLinksCatchesWhatFernMisses pins the checker, including that link syntax inside code spans and fences is ignored. The rule is also written down where each reader looks for it, so a contributor or an agent learns it before the test fails on their PR: CLAUDE.md and AGENTS.md next to the existing Fern site guidance, a Writing Documentation section in CONTRIBUTING.md, and the conventions list in the ADR index. Published v0.7.0 and v0.8.0 are built from their tags by hack/fern-freeze-versions.sh, so they keep their broken links (7 and 18) until the freeze script rewrites them; that is left for later. Signed-off-by: Kayne Tu <kaynet@nvidia.com> * test(docspolicy): follow CommonMark fence and code span rules stripCode closed a fence on any three-character marker, so a ~~~ line inside a ~~~~ block ended it early and the links after it were checked as prose. A fence now closes only on a run of its own marker at least as long as the opener, with nothing after it but whitespace. Code spans were stripped a line at a time, so a span that crossed a line ending was read as an unclosed backtick and a link inside it was reported as broken. Spans are now stripped a paragraph at a time; a blank line still ends an unclosed span. Line endings inside a removed span are kept so reference definitions stay line-anchored. Signed-off-by: Kayne Tu <kaynet@nvidia.com> * test(docspolicy): ignore indented fences and escaped backticks A fence marker indented four or more spaces is indented code, not a fence, but stripCode opened and closed fences at any indent, so such a line could hide the links that followed it. Both the opening and the closing fence now need at most three spaces of indent. A backslash-escaped backtick is literal, but stripCodeSpans opened a code span at it and dropped the links up to the next backtick. A backtick preceded by an odd number of backslashes no longer opens a span. Signed-off-by: Kayne Tu <kaynet@nvidia.com> * test(docspolicy): check links with any title form and HTML anchors inlineLink matched only a double-quoted title and no padding inside the parentheses, so a broken link written with a single-quoted or parenthesized title, or with whitespace around its destination, was never checked. Raw HTML anchors were not matched at all. Fern renders all of these as links. inlineLink now captures only the destination, the first token after `](` or a `<...>` destination, and ignores what follows, so a title in any form, or a form not listed here, cannot make the link invisible. htmlLink adds `<a href>` in either quote style. Each form has a broken case; the titled case that pointed at a nav page, and so passed with or without title handling, now sits beside off-nav cases that do pin it. Also correct the doc comment: v0.7.0 shipped seven such links, not three. Three was the distinct-ADR count. Signed-off-by: Kayne Tu <kaynet@nvidia.com> * docs: link ADR-101 by GitHub URL Signed-off-by: Kayne Tu <kaynet@nvidia.com> #537 added a relative ../designs/ link to ADR-101 in platform-detection.md, which renders as Page Not Found on the docs site. TestPublishedPagesLinkOnlyToPublishedPages caught it once main was merged into this branch. * test(docspolicy): check unquoted href, HTML images, and image files htmlLink matched only a quoted href, so <a href=../designs/x.md> was never checked, and <img src> was not matched at all. htmlAttr now takes an anchor's href or an image's src, quoted either way or unquoted. Images had the opposite problem. Every relative target had to be a nav page, so a Markdown image of a file that does exist under docs/, which Fern uploads with the page, would have been reported broken. No page uses one yet. A relative image, Markdown or HTML, now has to name a file under docs/ instead; a link to that same file still has to be a page. Signed-off-by: Kayne Tu <kaynet@nvidia.com> * test(docspolicy): match only a real href or src attribute htmlAttr found the attribute name after a word boundary, which a hyphen also gives, so in <a data-href="..." href="..."> it read data-href and never checked the real href. It also accepted src on an anchor and href on an image, so an anchor's src could stand in for its href. The attribute name must now follow whitespace, and each tag is paired with its own attribute in the pattern, so a non-matching attribute is skipped over rather than consumed.

… render (#532) * fix(certification): write render annotations in offline certification render Offline "nvcrectl certification render" (no --dry-run) resolved overrides against its synthetic node but discarded the result, so the rendered Workflows carried none of the nvcrectl.nvidia.com/ annotations (detected-platform, detected-gpu-architecture, applied-overrides). The --dry-run path and "nvcrectl workflow render", offline included, have always written them, and CLAUDE.md/AGENTS.md and ADR-075's testing plan tell readers to check them in offline render output. No ADR, doc or commit gives a reason for leaving them out; the discard dates to the initial commit. resolveWorkflowsOffline now passes the resolve metadata to render.SetRenderAnnotations. The values come from the synthetic node, so they record what override matching actually saw. That makes visible a case the output used to hide: without --platform the synthetic node has no providerID, detects as onprem, and the on-prem overrides apply, so the render is identical to --platform onprem. The annotations are informational. The controller never reads them, and no existing golden captures certification render stdout, so no existing test output changes. TestCertificationRenderAnnotations pins the three annotations through resolveWorkflowsOffline for AWS GB200 (two categories), AWS L20, GB300 without --platform (onprem), Nscale with --gpu-arch and no product label, and on-prem H100, where nothing matches and applied-overrides is omitted. The docs now name certification render beside workflow render, and CLAUDE.md/AGENTS.md note the onprem default.

Each entry adds its network to the worker pod's k8s.v1.cni.cncf.io/networks annotation in list order and requests count units (default 1) of its resourceName on the worker container, so the n-th network pairs with the n-th resource. The MPI launcher gets neither. The list owns the NIC wiring: it is mutually exclusive with nicResourceName, skips NIC auto-detection, and on OCI replaces the default sriov-net attachments and their mlnxnics request. CEL rules enforce the entry patterns, a 16-entry cap, and the exclusions with nicResourceName, rdmaDeviceAccess: hostPath and mlnxPerNode: 0; readCertification and readWorkloadRun mirror them offline. nvcrectl certification run gains --network-attachments network=resource[:count],... and the zipped --multus-networks / --extended-resources pair, which errors on a length mismatch. categoryOptionsSuffix gains a -net<N>-<hash8> token so categories that differ only in their attachments get distinct Workflows; it defers to #430. Design in ADR-101. Fixes #400 Signed-off-by: Anpoo Sivanadi <sivanadi08@gmail.com> * fix(api): drop networkAttachments count; one entry is one interface Review on #510 (kaynetu): an entry attaches one interface, so count > 1 reserved devices that nothing wires. A second interface on a network is a second entry, and entries that share a resourceName already add up. Remove NetworkAttachment.count and EffectiveCount(). Each entry now requests one unit of its resourceName. --network-attachments takes network=resource entries and rejects the old network=resource:count form with a pointer to repeating the entry. The Workflow name token hashes the (network, resourceName) pairs in list order, so the goldens that carry a net token get new names. Signed-off-by: Anpoo Sivanadi <sivanadi08@gmail.com> * fix(api): allow mlnxPerNode: 0 with networkAttachments; scope the NIC replacement to OCI Review on #510 (kaynetu): "the list owns the NIC wiring" only held on OCI. Azure, TogetherAI and Forge still render nvidia.com/mlnxnics next to the attachments, nscale renders its rdma claim, and the mlnxPerNode: 0 rule blocked the one setting that drops those requests. Keep the OCI gate (sriov-net is itself a Multus default, so the list replaces it) and do not gate the other platforms: they reach their InfiniBand fabric through those device-plugin or DRA requests and their NCCL environment names the HCAs, so dropping the request whenever a list is set would break the run. Instead remove the mlnxPerNode: 0 CEL rule from CategoryOptions and WorkloadRunSpec and from the offline mirrors, so a user who wants only the listed networks sets mlnxPerNode: 0 as on any other run (ADR-087). Tests: the two error cases become a WorkloadRun admission case that is accepted, and two TogetherAI H100 render goldens pin the request kept beside the list and dropped by mlnxPerNode: 0. Signed-off-by: Anpoo Sivanadi <sivanadi08@gmail.com> * fix(controller): check networkAttachments exclusions on the merged options Review on #510 (kaynetu): the CRD rules and readCertification read one options block at a time, so rdmaDeviceAccess: hostPath at the spec level and a list in a category (or the reverse) passed both and rendered a privileged pod with the /dev/infiniband mount and the attachment. Add controller.CheckResolvedNetworkAttachments and call it on each category's ResolveOptions result in createWorkflowForCategory and in renderCertification. The category fails (WorkflowValidationFailed on the controller, an error from render) with the way out in the message: devicePlugin in a category that inherits hostPath with a list, or nicResourceName in a category that inherits the list and needs hostPath. hostPath is not cleared in ResolveOptions the way nicResourceName is, because it changes how every container reaches the RDMA devices and dropping it silently would run a configuration nobody asked for. Tests: a controller golden for both directions and the two ways out, and two render-error goldens, one of them the review's exact spec. Signed-off-by: Anpoo Sivanadi <sivanadi08@gmail.com> * fix(controller): add a nic token to the Workflow name when a category sets nicResourceName Review on #510 (kaynetu): a category's nicResourceName replaces a spec-level networkAttachments list, so a category with no options (which inherits the list) and one that sets only nicResourceName attach to different fabrics but both rendered as c3-communication-nccl-all-4092a, and the second would have adopted the first's Workflow. categoryOptionsSuffix now adds nic<hash8> (SHA-256 of the resource name, hashed like env since the name carries a slash) whenever a category sets nicResourceName. This also separates two categories that name different NIC resources, which collided before this PR too. Categories that already set nicResourceName get a new Workflow name. An in-flight category is unaffected, since its Workflow is found through the recorded workflowRef; the renamed goldens are the two per-category NIC render cases and the certification-onprem-gb300-nccl reconcile case. Tests: a controller golden with the review's spec plus a third category on a different resource. Signed-off-by: Anpoo Sivanadi <sivanadi08@gmail.com> * docs(workloadrun): state that spec.overrides apply after networkAttachments; add the missing tests Review on #510 (kaynetu): the WorkloadRun comment said nothing later competes with the attachments, but the user's spec.overrides are applied when the Workflow reconciles, after the attachments, so an override that sets k8s.v1.cni.cncf.io/networks wins there while Certification's list is final. Keep that order and document it. spec.overrides is the last word on every other WorkloadRun field too, so making the list the one exception would be the surprise; Certification has no user overrides, which is the whole of the difference. Narrow the controller comment to platform overrides, say the same in pkg/workloadrun, and add it to the API reference. Tests the review asked for: - pkg/controller: a golden for the WorkloadRun controller path (buildWorkflowSpecWithWarning plus the Workflow's override pass): NIC detection skipped on an on-prem B300 that would otherwise pick rdma/ib, Azure's mlnxnics request kept beside the list and dropped by mlnxPerNode: 0, and a user override replacing the networks annotation. - pkg/platform: a golden for ApplyNetworkAttachmentsToDependencies: the catalog annotation replaced with siblings kept, entries on one resource adding up, the launcher untouched, the worker container by name else the first, and byte-for-byte pass-through for an empty list and a non-TrainingRuntime. Signed-off-by: Anpoo Sivanadi <sivanadi08@gmail.com> * docs(adr-101): correct how Multus matches networks to resources; record the gaps Review on #510 (kaynetu): the ADR and the API comments said the n-th network is wired to a device of the n-th requested resource. Multus does not pair by position: each NetworkAttachmentDefinition names its resource in k8s.v1.cni.cncf.io/resourceName, Multus takes the device allocated for that resource, and resources.limits keeps no order. What has to hold is that every attached network's resource is requested often enough. Restate that in the ADR context, the NetworkAttachment and field doc comments, the API and CLI references and the flag help, and say that an entry's resourceName must be the resource its NAD declares. Order still decides which network becomes net1..netN, which is why the name token hashes in list order; the rationale now says so. The ADR also gains: - "derive the resources from the NADs" as a considered alternative, rejected for now for the NAD RBAC, the Multus CRD dependency and offline render, with a compatible follow-up noted; - "gate every platform's NIC fragment" as a rejected alternative; - decision 3 scoped to OCI, the merged-options check, the nic name token and WorkloadRun override precedence, matching the code; - known gaps under Consequences: a wrong resourceName is not caught, transport fallback to NET/Socket can still pass, and a resource no node advertises leaves the pods Pending until the timeout. Signed-off-by: Anpoo Sivanadi <sivanadi08@gmail.com> * fix(platform): add networkAttachments to a platform-rendered resource request applyNetworkAttachmentsToJob wrote each resource's attachment count over the worker's limits and requests, so on a platform that already renders the same resource (nvidia.com/mlnxnics: 8 on TogetherAI or Azure) one entry on it shrank the request to 1. ADR-101 says the list adds to that request. The count is now added to the quantity already rendered: the limit when set, else the request, written to both so they stay equal. A quantity that cannot be parsed fails the call and leaves the dependency as it was. Where nothing was rendered for the resource, as on OCI with a list (the default mlnxnics fragment is gated off) or with mlnxPerNode: 0, the entries' count is the whole request, as before. The one helper serves the Certification transform stage and both WorkloadRun paths. New pkg/platform goldens cover 8 plus one entry (9), the same resource twice on top of 8 (10), a limit-only request and no platform request (1); a unit test covers the quantity forms; render goldens pin TogetherAI H100 (9) and OCI L40S (1) on nvidia.com/mlnxnics. ADR-101 and the API references state the addition. Reported by CodeRabbit on #510. Signed-off-by: Anpoo Sivanadi <sivanadi08@gmail.com> * docs(adr-104): renumber the network attachments ADR, say NIC entries add up, name the Certification-level failure ADR-101 went to the Akamai ADR (101-akamai-rtxpro6000-tcp) on main, and open PRs claim 102 (#539) and 103 (#543). The network attachments ADR moves to the next free number, 104: docs/designs/104-network-attachments.md, its README row, and the ADR links in the Certification and WorkloadRun API references. Follow-ups from the #510 approval: - Decision 2 and the networkAttachments API docs say outright that entries add to a NIC request the platform already rendered, so a site whose Multus networks are the platform's own NICs sets mlnxPerNode: 0 to request only the listed entries (two entries on nvidia.com/mlnxnics on TogetherAI otherwise request 10). - Decision 3, the API docs and the CheckResolvedNetworkAttachments comment say that a hostPath conflict found on a category's merged options fails the whole Certification as WorkflowValidationFailed, naming the category, not the category alone. - The ADR's known-gaps list marks where the transport-fallback (#TBD1) and allocatable (#TBD2) follow-up issues will be linked. CRDs regenerated with make manifests. Signed-off-by: Anpoo Sivanadi <sivanadi08@gmail.com> * fix(platform): add networkAttachments to platform override requests Review follow-ups for #510 (ndipebot). Ordering: a WorkloadRun's platform overrides are not applied when the Workflow spec is built. They travel in spec.overrides and the Workflow controller applies them later, replacing scalars, so Azure's nvidia.com/mlnxnics: 8 replaced 8 plus one networkAttachments entry and the run asked for 8. The new platform.ApplyNetworkAttachmentsToOverrides raises every platform override patch that already requests one of the listed resources by the same count, and writes the networks annotation into any patch that sets one. It runs after BuildOverrides in both the controller and BuildWorkflowSpec, together with the runtime write that moves there too. Azure H100 plus one mlnxnics entry now requests 9 on workloadrun render, the WorkloadRun controller and certification render. The user's spec.overrides are appended untouched and still win. Tests: - render-network-attachments (azure, togetherai), workloadrun-network-attachments/azure-h100-same-resource-adds and certification-render-network-attachments/azure-h100-same-resource-adds pin the 9, plus TestApplyNetworkAttachmentsToOverrides. - read-workloadrun error cases: upper-case network, a kubernetes.io/ resource, 17 entries, an empty list, and a list with nicResourceName. - reconcile/certification-network-attachments-merged-hostpath: a category list merged with a spec-level rdmaDeviceAccess: hostPath fails the whole Certification with WorkflowValidationFailed and creates no Workflow. - TestNewRunCommandValidation: --cert-file with --network-attachments, --multus-networks, --extended-resources, and the pair. - certification-render-network-attachments/onprem-b300-skips-nic-detection and TestApplyWRNICDetection pin the NIC-detection skip for an explicit list. The WorkloadRun dry-run gate moves into applyWRNICDetection. ADR-104 Decision 3 now says a conflict fails the whole Certification, and Decision 6 describes the override handling. The #TBD placeholders are gone. Two goldens from this PR are refreshed for main: the build-workflow-spec mpi-network-attachments override count (Akamai's override from #537) and the certification-onprem-b300-multirail worker sshd script (#528). Signed-off-by: Anpoo Sivanadi <sivanadi08@gmail.com> * fix(platform): pick the override worker container as the runtime path does applyNetworkAttachmentsToPatchJob matched the worker container only by the exact name "node", while the runtime path falls back to the first container. A platform override on a replicatedJob without a "node" container could then keep its own count on the same container the runtime had raised. Both paths now go through workerContainer, which also returns nil for an empty list. Reword the "compute every sum before writing any" comments: the annotation or the resources maps may already be touched on error, and what keeps the dependency intact is that the caller returns before re-marshalling. Add the override case worker-container-by-name-else-first, and say in ADR-104 that the override path picks the worker as the render step does.

Summary
Akamai LKE GPU nodes currently fall back to
onprembecause their provider IDs start withlinode://. Registerakamai, detect those nodes, and support--platform akamaifor offline CLI rendering.Add RTX PRO 6000 TCP settings shared by NCCL all-reduce/all-gather/alltoall, Nemotron 5 8B, and MPI/Torch WorkloadRuns: use
eth0, disable InfiniBand and the external network plugin, and setNCCL_P2P_DISABLE=1for unqualified multi-GPU VMs. Keep the architecture default of eight GPUs; one-GPU development VMs require explicitgpusPerNode: 1. The inspected LKE GPU nodes are untainted and expose standard GPU resources, so no RDMA resource requests or additional GPU taint tolerations are added.Akamai TCP users must explicitly set
maxBytes: 1G,numIterations: 20, andnumCycles: 1for all three NCCL collectives; the generic 16G/100/10 benchmark cannot finish within the launcher timeout at the measured bandwidth. Generic defaults remain unchanged. ADR-101 records the choices and qualification scope.Related Issue
