Summary

Documents the DGDR workload-creation trust boundary instead of enforcing a PodSpec deny-list in the operator.

Following a Kubernetes security review (thanks @sttts), an operator-side deny-list of privileged PodSpec fields enforces security at the wrong layer. Creating a DynamoGraphDeploymentRequest is workload-creation authority in its namespace — it carries the same security blast radius as creating an equivalent Job or Pod there. Pod-level security is enforced centrally by Pod Security Admission on the resulting Pods; an operator deny-list would only partially duplicate the Pod Security Standards, drift from upstream as the API evolves, and imply a guarantee it cannot provide.

The one hard invariant — namespace containment — is already structurally guaranteed: the profiling Job is created in dgdr.Namespace, and the override API is a JobSpec with no namespace field, so a DGDR cannot escape its namespace.

Changes (docs only)

  • DGDR guide (auto-deploy-with-dgdr.md): new subsection on profilingJob overrides and the trust boundary, leading with the general principle — any principal that can create workloads in a namespace where Dynamo runs is inside that namespace's trust boundary — and pointing operators to Pod Security Admission + RBAC good practices.
  • DGDR API godoc (OverridesSpec.ProfilingJob): documents the same contract at the API surface.

The earlier deny-list validator has been reverted; this PR is now docs-only.

Validation

  • Docs-only; Fern link/asset checks pass in pre-commit.

Supersedes the deny-list approach discussed in the review thread.

Review Change Stack

Walkthrough

Profiling Job override handling now validates security-sensitive fields, aggregates violations, and returns errors. Profiling Job construction stops when validation fails. Tests cover rejected escalation settings and accepted benign overrides.

Profiling Job construction returns override errors. Tests cover rejected settings, benign FSGroup and RunAsUser overrides, and unchanged defaults.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟠 High · up to d7963

The change blocks several privileged profiling overrides, but users can still select workload identity or expose Kubernetes Secrets to the profiling Pod. These security-sensitive paths should be rejected before merge.

I think this enforces security at the wrong boundary.

Kubernetes treats permission to create Pods—or workload resources that create Pods—as workload-creation authority within a namespace. The upstream RBAC guidance explicitly says that such permission implicitly grants access to mountable namespace resources and the permissions of ServiceAccounts in that namespace. It consequently states that “namespaces should be used to separate resources requiring different levels of trust or tenancy” and that “boundaries within a namespace should be considered weak.”
Kubernetes RBAC good practices: Workload creation

Pod security is then enforced centrally on the resulting Pods. Pod Security Admission applies Pod Security Standards at namespace level when Pods are created. For workload resources such as Jobs and Deployments, Kubernetes deliberately applies warn and audit to their templates for early feedback, but applies enforce only to the resulting Pod objects.
Pod Security Admission: Workload resources and Pod templates
Enforcing Pod Security Standards

DGDR should preserve these Kubernetes invariants:

  1. Creating a DGDR is workload-creation authority in the DGDR’s namespace and therefore has the same security blast radius as creating an equivalent Job or Pod there.
  2. The namespace is controller-owned and must not be overrideable. In the current implementation, the profiling Job is explicitly created in dgdr.Namespace; the API exposes a batchv1.JobSpec, not a complete Job, and the override merge does not copy a namespace from the Pod template.
  3. Every resulting Pod must pass the namespace’s normal admission policy, without an operator-specific bypass. Upstream specifically cautions against exempting controller ServiceAccounts, because that would implicitly exempt users who can create the corresponding workload resources.
  4. Defense in depth belongs at Pod admission. Checks on a workload template may provide earlier warnings, but they must not become a workload-specific security boundary.

A DGDR-specific deny-list of selected PodSpec fields duplicates only part of the Kubernetes Pod Security Standards, will inevitably drift as the Kubernetes API evolves, behaves differently from standard workload APIs, and risks implying a security guarantee that it cannot provide.

I therefore suggest removing this deny-list and documenting the invariants above clearly in both the DGDR API and the Security Overview. If the intended threat model is that DGDR authors are less trusted than users allowed to create Pods or Jobs in the namespace, then exposing an arbitrary JobSpec is the wrong API contract; we should expose a narrow, typed profiling configuration instead. The resulting Pods must still remain subject to normal Pod admission in either case.

Current namespace behavior: Job creation, DGDR API type, override merge.

Per Kubernetes security review, an operator-side PodSpec deny-list enforces
security at the wrong layer: creating a DGDR is workload-creation authority in
its namespace, so it carries the same blast radius as creating a Job/Pod there.
Pod-level security belongs at Pod Security Admission on the resulting Pods, not
in a partial deny-list that duplicates the Pod Security Standards and drifts from
upstream.

Document the contract instead of enforcing it in the operator:
- DGDR guide: a subsection on profilingJob overrides and the trust boundary,
  leading with the general principle (any principal that can create workloads in
  a Dynamo namespace is inside that namespace's trust boundary).
- DGDR API godoc (OverridesSpec.ProfilingJob): same contract, at the API surface.

This replaces the deny-list validator approach (reverted).

Fully agree, and thanks for the detailed writeup with the upstream references — this is the right framing.

Decision: we'll treat creating a DGDR as carrying the same privilege as creating a Pod/Job in its namespace, and follow the standard Kubernetes trust boundary — Pod Security Admission enforces on the resulting Pods, and the namespace is the tenancy boundary. We won't re-implement a partial Pod Security Standards deny-list in the operator, since it would drift from upstream and imply a guarantee it can't provide.

Concretely:

  • Dropped the PodSpec deny-list validator; this PR is now docs-only.
  • Documented the contract in the DGDR guide and the OverridesSpec.ProfilingJob API godoc, leading with the general principle: any principal that can create workloads in a namespace where Dynamo runs is inside that namespace's trust boundary; creating a DGDR is one such path, no more privileged than creating a Job/Pod there; defense-in-depth belongs at Pod admission.
  • The namespace stays controller-owned and non-overridable (the Job is created in dgdr.Namespace; the override API is a JobSpec with no namespace field) — so the one invariant that matters is already structurally guaranteed.

Docs-only review of 56de603c2f, checked out locally against merge base 41a0faa0f1 from the compare API. I verified every claim by reading the code and by running the operator package.

What I verified as correct

The namespace invariant holds

I added a temporary Go test that calls applyProfilingJobOverrides with template.metadata.namespace set to a different value. The merged Job keeps the controller namespace:

job.Namespace="dgdr-ns" templateNamespace="dgdr-ns" templateName="" serviceAccountName="other-sa"

applyProfilingJobOverrides merges only the JobSpec scalars and the pod template labels, annotations and PodSpec (deploy/operator/internal/controller/profiling_job_overrides.go:45-51, :268-272). It never reads overrides.Template.ObjectMeta.Namespace. The Job namespace comes from dgdr.Namespace (deploy/operator/internal/controller/dynamographdeploymentrequest_controller.go:1659). Both halves of the stated invariant are accurate.

A note, not a finding: the reason the invariant holds is the allowlist merge, not the shape of the API. make manifests runs controller-gen with generateEmbeddedObjectMeta=true (deploy/operator/Makefile:241), so the CRD does accept spec.overrides.profilingJob.template.metadata.namespace (deploy/operator/config/crd/bases/nvidia.com_dynamographdeploymentrequests.yaml:1149). The merge ignores it today, so the godoc sentence is true as written. The pull request description says the override API has "no namespace field", which is true of the top-level JobSpec and not of the nested pod template metadata.

The earlier validator is gone and nothing else went with it

The diff against 41a0faa0f1 touches two files and adds 34 lines. profiling_job_overrides.go at the merge base contains no validation function, so nothing was removed from main. I found no test, document or caller that still names the removed validator. The two bot comments on profiling_job_overrides.go predate this rewrite and no longer apply to the current head.

Style and lint

python3 docs/fern/scripts/docs_lint.py reports 0 errors. The page keeps its SPDX header and Fern frontmatter, starts the body at ##, and uses a GitHub-style > [!IMPORTANT] block.

Findings

Three P2 findings are inline. One P3 has no line in the diff, so it is here.

P3. The guidance does not reach the reader who installs Dynamo

docs/fern/pages/developer-guide/security/secure-deployment-guidelines.md has a section "Running with Least Privilege" with a "Kubernetes deployments" subsection at line 253. It lists RBAC, NetworkPolicies and non-root pods. It does not name Pod Security Admission. Across the whole repository, the only other match for pod-security.kubernetes.io is one unrelated line in docs/fern/pages/kubernetes/installation/rdma-setup/infiniband-on-azure.mdx:52.

The new subsection sits at line 455 of a 490-line DGDR guide, inside "Optional: Customize the generated DGD". An operator who follows the install path does not reach it. The review thread asked for the DGDR API and the security overview. Please add the same two sentences to the security guide, so the guidance sits where an operator looks for it.

Not approving yet

The bar is zero P0, zero P1, and fewer than four combined P2 and P3. The count is three P2 and one P3, all about what the documentation states and where it sits. None of them contests the engineering decision, which I read as sound and well supported in the thread.

…steps

Address Dmitry's docs-only review on #14429:

- PSA governs the Pod's security *context*, not its *identity*. Split the
  godoc and the trust-boundary admonition to say so: serviceAccountName and
  automountServiceAccountToken flow through overrides.profilingJob and are
  bounded by RBAC and namespace membership, not PSA — the same authority any
  Pod author in the namespace already holds.
- Tell readers how to actually turn PSA on: it applies no policy until the
  namespace carries pod-security.kubernetes.io/enforce=<level> labels.
- Regenerate the committed Kubernetes API reference so the updated godoc
  reaches the published reference (make generate-api-docs + gen_kubernetes_api.py).

Incorporate Faisal Tameesh's (ThreatOps) hardening feedback: the object-level
namespace invariant does not by itself provide node or cross-tenant isolation.
If admission permits privileged containers, host namespaces, host devices, or
hostPath mounts, a DGDR creator can obtain those capabilities through the
operator — so the guidance is to apply non-exempt Pod Security Admission (or
equivalent policy) to every resulting Pod, not merely rely on the namespace
boundary. Update the doc and godoc, and regenerate the API reference.

Follow-up round 2. Reviewed at head 26a01ca29e against merge base 41a0faa0f1, checked out in a local worktree. The head moved twice while I worked, from 56de603c2f to 3ff64033f and then to 26a01ca29e. Everything below reads the final head. The delta from the merge base is 4 files, 53 added lines and 2 removed lines.

Status of my round 1 findings

  • Guide does not tell the reader to enable Pod Security Admission. Partly fixed, and the new text adds a P1. Details in the thread on auto-deploy-with-dgdr.md.
  • Godoc claims Pod Security Admission covers fields it does not cover. Fixed. Thread resolved with the evidence.
  • The godoc text does not reach the published API reference. Partly fixed. Two generated pages are now correct. The CRD manifest and the generated Pydantic model are still stale. Thread stays open.
  • P3 from my round 1 body: docs/fern/pages/developer-guide/security/secure-deployment-guidelines.md still does not name Pod Security Admission. Untouched. The request stands, and it stays P3.

The new Go lines

The 16 added lines in dynamographdeploymentrequest_types.go are a field comment and nothing else. They add no +kubebuilder marker and no schema. I confirmed that nothing enforces them. deploy/operator/internal/webhook/validation/dynamographdeploymentrequest.go contains no reference to Overrides or to ProfilingJob, so the validating webhook never reads the field. go build ./api/... passes.

That is the correct result here, because the comment says so itself: it states that Pod Security Admission enforces the Pod security context "not by this API". The comment describes a control that lives outside this repository, and it does not promise enforcement that the code skips.

The generated pages

I installed controller-gen v0.17.3 and crd-ref-docs v0.3.0 and ran the generators in the worktree.

  • make -C deploy/operator generate-api-docs reproduces api-reference-k8s.md byte for byte.
  • python3 docs/fern/scripts/gen_kubernetes_api.py prints full-api-reference.mdx: unchanged.

Both generated pages match the Go type at this head. No hand edit.

make -C deploy/operator manifests does not match. It adds 16 lines to nvidia.com_dynamographdeploymentrequests.yaml. python3 deploy/operator/api/scripts/generate_pydantic_from_go.py also rewrites the profilingJob description in components/src/dynamo/profiler/utils/dgdr_v1beta1_types.py. Evidence is in the open thread.

The new documentation text

The line between Pod Security Admission and ServiceAccount identity is drawn correctly. Pod Security Admission decides on the Pod specification against the namespace label, and the page now says that it does not decide which identity the Pod runs as. The new paragraph on node and cross-tenant isolation is also accurate. Namespace containment keeps the object in one namespace, and it does not stop a privileged container from reaching the node.

The enable steps do not work as written for one of the two levels they offer. That is the P1 in the thread.

One new P3 is inline, on how the page describes the scope of Pod Security Admission.

Not approving

Open count is one P1, one P2 and two P3. The bar is zero P0, zero P1 and fewer than four combined P2 and P3.

Thanks for the thorough docs-only pass, Dmitry — especially reproducing the namespace invariant with a live test. All three P2s addressed, plus a related hardening note from ThreatOps:

P2 (enable-PSA steps): the admonition now tells readers to label the namespace (pod-security.kubernetes.io/enforce: <level> + matching audit/warn), since PSA is inert until then.

P2 (two fields outside PSA): good catch — the godoc and doc now split the claim: PSA governs the Pod's security context; serviceAccountName / automountServiceAccountToken identity is a separate RBAC/namespace layer (the same authority any Pod author in the namespace already holds).

P2 (godoc didn't reach the published reference): regenerated both stages, so api-reference-k8s.md and full-api-reference.mdx carry the new text — which was also the red operator check.

One more, folded in from a parallel ThreatOps review: namespace containment isn't node or cross-tenant isolation. If admission permits privileged containers / host namespaces / host devices / hostPath, a DGDR creator can obtain those through the operator — so the guidance is now to apply non-exempt PSA to every resulting Pod rather than lean on the namespace boundary.

Thank you. I re-checked the live head before writing this. It is still 26a01ca29e, so the measurements below are current.

Two of the three points match what I measured. One does not.

ServiceAccount identity. Agreed, and closed. I resolved that thread.

Namespace containment. I agree with the ThreatOps note, and the paragraph states it accurately. Namespace containment keeps the object in one namespace. It does not stop a privileged container from reaching the node, and it is not a tenant boundary. The wording is correct and the reader gains a real distinction from it.

Enable steps for Pod Security Admission. The form is now complete. The page names the label, the levels, and the fact that Pod Security Admission stays inert before the label exists. The level it recommends is still wrong. The page offers restricted, and the profiling Job that the same page documents fails restricted. My probe returned baseline: ALLOW and three denials under restricted, each naming the profiler container and the output-copier container. That is the open P1, with the full output and two ways to close it, in the thread on auto-deploy-with-dgdr.md.

Generated artifacts. Two of four are current. Two are not.

Current, and I confirm your claim for both. make -C deploy/operator generate-api-docs reproduces docs/fern/pages/reference/kubernetes-api/additional-resources/api-reference-k8s.md with zero diff, and python3 docs/fern/scripts/gen_kubernetes_api.py prints full-api-reference.mdx: unchanged.

Stale, at this head:

make -C deploy/operator manifests
# adds 16 lines to deploy/operator/config/crd/bases/nvidia.com_dynamographdeploymentrequests.yaml

python3 deploy/operator/api/scripts/generate_pydantic_from_go.py
# rewrites the profilingJob description in components/src/dynamo/profiler/utils/dgdr_v1beta1_types.py

The committed CRD carries only the two original sentences at nvidia.com_dynamographdeploymentrequests.yaml:776-779, so kubectl explain dgdr.spec.overrides.profilingJob still shows the old text. The committed Pydantic model carries the old description at dgdr_v1beta1_types.py:177, and its header names the generator above. Run black on the Pydantic output before you commit it, because the script reflows the rest of the file when black is absent.

I found no workflow under .github/ that runs controller-gen, generate-api-docs, or generate_pydantic_from_go.py. No job compares those two files against the Go type, so this drift ships without a signal.

Verdict is unchanged while the P1 is open.

… Standards

Address Dmitry's round-2 review on #14429:

- P1: the page offered 'restricted' as a PSA level, but the operator-built
  profiling Pod (and Dynamo's workloads generally) do not set the container
  hardening restricted requires (allowPrivilegeEscalation=false, drop ALL caps,
  seccompProfile). They satisfy 'baseline'. Recommend enforcing 'baseline' only
  — it forbids exactly the node-escape vectors (privileged, host namespaces,
  host devices, hostPath) that the finding depends on, and Dynamo meets it, so
  the guidance no longer silently blocks profiling.
- P3: 'security context' understated PSA's scope. PSA enforces the full Pod
  Security Standards (privileged, host namespaces, hostPath, host ports), which
  the containment paragraph relies on. Broadened the wording; kept the
  RBAC-vs-PSA ServiceAccount-identity split.

Regenerated all four artifacts from the godoc (CRD manifest, api-reference-k8s.md,
full-api-reference.mdx, Pydantic model).

Reviewed at head 742b571f2 against merge base e5ef9d778b, in a local worktree. Round 2 read 26a01ca29e against merge base 41a0faa0f1. The base moved by seven commits and the author added one commit, 96188bb5eb, plus the merge itself. I compared the two three-dot diffs and then compared each file blob, so the base movement is separated from the author content.

The delta carried author content

96188bb5eb rewrote the Pod Security Admission guidance and regenerated the CRD manifest and the Pydantic model. None of the seven incoming main commits touches a path in this pull request. I checked each one by its own file list, not by its subject line: e5ef9d778b, 232f881e07, 4df3f3af83, 69f4476c54, 0cb120e1f0, a1c9d4cafc and 633776f89a all land outside deploy/operator/api, components/src/dynamo/profiler and docs/fern. The 8 added lines in the guide, the 2 reworded lines in each generated reference page, the 16 new lines in the CRD manifest and the 1 changed line in the Pydantic model are all author content.

Findings closed this round

The P1 about the restricted level is fixed. The page no longer offers that level. It names baseline as the level the profiling Job meets and tells the reader to enforce it. I replaced the weaker evidence on that thread with a live-cluster run on k3s, which confirms both halves: baseline admits the Job, and restricted rejects its Pods while the DGDR keeps reporting progress that never ends. Details are in the thread.

The P3 about the scope of Pod Security Admission is fixed. The page now states the full Pod Security Standards scope, and the closing paragraph no longer contradicts it.

The generated-artifact thread is closed. make -C deploy/operator check passes on a clean tree at this head, and gen_kubernetes_api.py --check prints full-api-reference.mdx: unchanged. I withdrew that finding as a defect in round 2, because the repository already gates all four files in that one target.

Round 2 results still hold

The godoc still separates the two layers. deploy/operator/api/v1beta1/dynamographdeploymentrequest_types.go:306-308 still states that serviceAccountName and automountServiceAccountToken are bounded by RBAC and namespace membership rather than by Pod Security Admission. Nothing undid it.

Both Fern pages still reproduce from their generators with no diff, in the same run described above.

docs_lint.py reports 0 errors over 462 files.

One P3 stays open

docs/fern/pages/developer-guide/security/secure-deployment-guidelines.md still does not name Pod Security Admission. The "Kubernetes deployments" subsection at line 255 lists RBAC, NetworkPolicies and non-root pods. Across the repository the only other match for pod-security.kubernetes.io is one unrelated line in docs/fern/pages/kubernetes/installation/rdma-setup/infiniband-on-azure.mdx:52. An operator who follows the install path does not reach the DGDR guide, so the guidance does not sit where that reader looks for it. This is a small, separable follow-up and it does not block the merge.

Open count is zero P0, zero P1, zero P2 and one P3.

My thoughts

The framing is right and reverting the deny-list was the correct call. Two claims in the new text do not match what the operator does, and both are worth fixing before this lands, because the point of the page is to state the boundary exactly. I left those inline.

Both claims also sit in the godoc at dynamographdeploymentrequest_types.go:302-311, so the CRD and the Pydantic model need regenerating after the edit.

The allowlist itself is undocumented, which is worth a line while you are in here. The new section says the field accepts a partial JobSpec, but only about twenty fields are merged and the rest are dropped without an error, including schedulerName, restartPolicy, container ports, and any container other than profiler or output-copier.

I checked the rest at 742b571f: the generated CRD, full-api-reference.mdx, and the Pydantic model all regenerate byte-identical, docs lint is clean, and the namespace-containment claim holds, since the Job takes its namespace from dgdr.Namespace and the override path only touches job.Spec.

The profiling Job does satisfy baseline, but "Dynamo's operator-generated workloads" does not: the inter-pod GMS layout mounts a hostPath at /run/gms on the weight-server pod and the engine pods (deploy/operator/internal/dynamo/failover.go:212-229, reached from graph.go:2823 and graph.go:2843 when Experimental.GPUMemoryService.Mode is interpod). Baseline forbids hostPath outright, and the comment at failover.go:243-246 already expects baseline to reject that init container. So an operator who reads "enforce baseline while keeping Dynamo running" and does it non-exempt gets GMS pods rejected at admission.

it — but namespace containment is not node or cross-tenant isolation. If admission permits
privileged containers, host namespaces, host devices, or `hostPath` mounts, a DGDR creator can
obtain those capabilities through the operator, exactly as any Pod author in the namespace could.

This one points the other way and overstates the surface by one item. applyPodSpecOverrides (profiling_job_overrides.go:325-382) is an allowlist and never copies HostNetwork, HostPID, or HostIPC, so host namespaces are silently dropped. Privileged and hostPath are reachable, through the wholesale container SecurityContext replace at :423-425 and the Volumes and InitContainers merge at :369-370. Dropping "host namespaces" from the list keeps the rest of the sentence true.

* fix(sglang): validate diffusion input_reference and bound media fetches (ai-dynamo#14435)

The sglang image-diffusion and video-generation handlers passed the
client-supplied input_reference through to the generator's image_path after only
a non-empty check. Validate it first, and for remote references materialize it
locally before the generator sees it, so the generator is always handed a
trusted local path. This brings the sglang diffusion path in line with the
vLLM/omni and trtllm backends, which already validate the same field.

Behavior change: local I2I/I2V references now require DYN_MM_LOCAL_PATH to be
set to the allowed directory; previously any path was accepted.

common/http:

- validate_media_reference() returns a plain filesystem path for local
  references; local_media_reference() is an async context manager that fetches a
  remote one through fetch_bytes(policy=...), which revalidates every redirect
  hop, into a temp file removed on exit. data: is rejected -- a URI is not a path.
- fetch_bytes() gained max_bytes, streaming through collect_capped at an explicit
  read granularity so the cap is an allocation bound and not only a rejection: a
  128 MiB-decoded gzip body against the 64 MiB cap peaks at 68,032,217 bytes
  rather than the whole decompressed body. Content-Length is caller-controlled
  and absent when chunked, and aiohttp's read(n) returns at most n bytes, so
  neither a header check nor a single capped read suffices. Defaults to None,
  leaving existing callers unchanged.
- DYN_MM_MAX_FILE_SIZE_MB makes that cap operator-tunable, in megabytes, as the
  SGLang arg it replaces was. Read per call; empty, unparseable or non-positive
  falls back to 64 with a warning, so a malformed value neither takes the worker
  down nor reads as unlimited.
- Messages built from caller input are bounded via describe_media_source, moved
  from multimodal/media_source.py (it pulls in torch) into url_validator.py and
  re-exported from its old home; a no-op below 120 characters.
- HttpStatusError bounds its .message attribute, not only the rendered string:
  errors.rs::extract_http_like_error reads .status and .message off this class by
  name and forwards .message on a 4xx without calling str(). Backend exception
  text is bounded head-and-tail, since aiohttp renders the host before the errno.
- validate_local_path uses exc.strerror rather than the raw OSError, whose text
  repeats the filename, and now catches the ValueError that Path.resolve() raises
  on an embedded NUL so callers keep their 4xx-vs-5xx decision.

Rebased onto ai-dynamo#14563 (single aiohttp backend); the httpx-side half of the
max_bytes plumbing went with that backend.

* ci(xpu): validation PR for the re-applied XPU workflows and Dockerfile

Throwaway PR to prove the CI merged in #22 actually runs end to end on XPU
hardware. Adds only a comment to container/templates/vllm_runtime.Dockerfile,
which matches the `vllm` path filter (container/templates/vllm_*) and so makes
changed-files set vllm=true, which is what gates build-xpu and the
heterog-test-px-dn / heterog-test-pn-dx jobs.

What this exercises:
  - .github/workflows/pr-xpu.yaml            (push to pull-request/[0-9]+, needs the xpu label)
  - .github/workflows/pr-xpu-heterogeneous.yaml (push; its guard deliberately skips the label gate)
  - .github/workflows/epd-test-template.yml  (workflow_call, from the heterog jobs)
  - .github/scripts/test-filters.js          (the brace fix from #22)
  - container/templates/vllm_runtime.Dockerfile rendered and built for device=xpu

Not exercised: .github/workflows/xpu-heterogeneous-dispatch.yaml is
workflow_dispatch only and has to be run by hand from the Actions tab.

The marker comment must be removed before this branch is ever merged.

names (`FP32`, `BYTES`, ...). Every datatype was wrong, so spec-conforming
clients cannot parse any tensor the RPC describes. Adds `oip_name()` next to
`tensor::DataType::to_kserve` covering all fifteen proto variants (incl. FP16
and BF16) and mapping `TYPE_STRING → BYTES`.

* feat: KVCR Resiliency Deployment Example (ai-dynamo#14695)

Add two-node DynamoGraphDeployment examples for process-local KVCR and
the KVCR memory service. Run one vLLM worker per GPU node, use stable
Grove ordinals for cache-owner slots, and request GPU-local RDMA
resources for engines and Guard services. Provide a deployment helper
for rendering and selecting either variant.

Run the KV state agent alongside vLLM for process-local host memory. In
memory-service mode, keep KVCR and the state agent in a separate
container so its Guard and shared-memory pool survive engine restarts.
Document that restarting the services sidecar invalidates the MVP
recovery contract and requires deployment-level replacement.

Add manifest coverage and an opt-in two-host lifecycle test. Kill the
source EngineCore, hold it offline, and verify that the promoted Guard
serves its preserved cache to the surviving target. Correlate response
equality and KVCR transfer metrics with transmit and receive counters
from the selected active HCA to prove RDMA transport.

Pin compatible KVCR and vLLM revisions and document the runtime,
discovery, compatibility-digest, and recovery prerequisites.

* .github/workflows/pr-xpu-heterogeneous.yaml; pin GPU_TAG to latest

* .github/workflows/; add post-merge and nightly XPU heterogeneous CI

Extract the XPU heterogeneous P/D pipeline out of pr-xpu-heterogeneous.yaml
into xpu-heterogeneous-run.yml, a workflow_call reusable workflow, and call it
from three thin trigger workflows so all three merge phases run the identical
pipeline instead of drifting copies.

  xpu-heterogeneous-run.yml           new, reusable. guard, changed-files,
                                      build-xpu, build-nvidia, resolve-images
                                      and both heterog tests, unchanged, plus
                                      7 inputs.
  pr-xpu-heterogeneous.yaml           reduced to the pre-merge trigger, the
                                      slash-command gate and the reaction.
  post-merge-xpu-heterogeneous.yaml   new. push to main.
  nightly-xpu-heterogeneous.yaml      new file, but the cron is MOVED, not
                                      added: it is the 0 23 * * * schedule
                                      that was already in
                                      pr-xpu-heterogeneous.yaml.

No behaviour change per phase. force_all_tests replaces the old
  github.event_name == 'schedule' || github.event_name == 'issue_comment'
expression with the same truth table: pre-merge passes
github.event_name == 'issue_comment', nightly passes true. Post-merge also
passes true, because a push to main has no PR base for
.github/actions/changed-files to diff against, and post-merge exists to catch
what per-PR gating missed.

xpu-status-check stays a TOP-LEVEL job in each caller rather than moving into
the reusable workflow. A job contributed by a reusable workflow reports to the
Checks API as "run / xpu-status-check", so hosting it there would rename the
context and leave any branch protection rule requiring xpu-status-check waiting
forever on a check that no longer reports.

The concurrency mapping stays byte-identical across all four workflows that
touch this hardware, now including xpu-heterogeneous-dispatch.yaml. Three files
do NOT get three slots: the cluster, the dynamo-system namespace and the
onexpu-/onenvidia-rdma-kueue ResourceClaimTemplates are one global resource.
The reusable workflow deliberately carries no concurrency block of its own,
which would deadlock against the slot the caller's run already holds.

Parameterised gpu_tag, model, tensor_parallel and runner as inputs so the
callers can diverge; all default to the previously hardcoded values. Added
workflow_dispatch to the nightly, without which a schedule-only workflow cannot
be exercised before it reaches the default branch.

Verified: all files parse; the four concurrency mappings are byte-identical; the
reusable workflow declares no concurrency; every input each caller passes exists
and every required input is supplied; nesting is depth 3 of the 4 GitHub allows.
actionlint was not available to run, and will report queue:max as an unknown key
in all four files, a known false positive.
