- Around line 43-51: Update the networking probe instructions around the
tcp-probe command to cover cross-nodegroup connectivity: after identifying the

tolerations, and endpoint-specific ports.
- Around line 81-83: Update the networking documentation rules around the
GPU-to-system security-group entries and corresponding AWS commands to use
separate direction-specific, per-port rules: document frontend-to-worker access
independently from worker-to-frontend ZMQ KV events on ports 5557 and dp_rank,
and after the 1.4.x chart is available, verify and document the exact TCP
request-plane listener separately.

🔬 Multi-persona review — Dynamo 1.4+ / NATS removal
Method: 3 parallel persona reviewers (Recipe/Domain correctness · CI-DX/Operability · Docs consistency) → an adversarial senior meta-reviewer that re-derived every finding from the resolved code at 053a47a0. Both blockers were reproduced from source.
Duplicate-work note: @mchmarny already has a standing Request changes here. His BLOCKER (registry <NEW_VERSION> placeholder) is now addressed by pinning 1.4.1; his MAJOR (unfinished <PORT> networking contract + UAT still on NATS 4222) is still open and maps to F4/F5 below. The two 🔴 blockers (F1, F2) were not caught by the prior reviews.
The change shape is correct — remove bundled NATS to match Dynamo 1.4+'s TCP/ZMQ defaults, bump the pin, adjust the conformance asserts. But it's incomplete two CI-hard ways and one consistency way: it won't pass CI as-is, and the NATS removal is only ~half-applied across the repo.
Recommendation: request changes (blocking on F1 + F2 at minimum). Legend: 🔴 Blocker · 🟠 Major · 🟡 Minor · 🔵 Nitpick.
🔴 Blockers (fail CI)
🔴 F1 — Two bundler tests still assert the removed NATS storageClass wiring → make test fails. pkg/bundler/bundler_test.go. The PR removed storageClassPaths: [nats.config.jetstream.fileStore.pvc.storageClassName] from the dynamo-platform registry entry and the NATS PVC block from values.yaml, but left the two guard tests: TestApplyNodeSchedulingOverrides_DynamoPlatformStorageClass t.Fatalfs at :2350 (empty GetStorageClassPaths()), and TestWarnMissingStorageClassForPVCs_DynamoPlatformNATS expects wantWarning:true but warnMissingStorageClassForPVCs (bundler.go:1702) loops the now-empty paths → no warning → t.Fatalf at :3052. Fix: delete both dynamo-platform-specific tests (the feature they guard was intentionally removed); keep the kube-prometheus-stack variants.
🔴 F2 — BOM not regenerated → required bom-freshness merge-gate fails (1.2.1 ≠ 1.4.1). docs/user/container-images.md:39 still lists dynamo-platform 1.2.1 and the removed NATS images (nats:2.10.21-alpine, natsio/nats-server-config-reloader:0.16.0, kubernetes-operator:1.2.1), while registry.yaml:527 pins 1.4.1. TestCommittedBOMVersionsMatchRegistry hits its mismatch branch; the bom path filter includes recipes/registry.yaml and bom-freshness is in the required gate job's needs → deterministic failure. Fix: make bom-docs and commit the regenerated doc.
🟠 Major
🟠 F3 — UAT tests/uat/lib/phases.sh:105 still defaults SERVE_RUNTIME_IMAGE to vllm-runtime:1.2.1. The comment above it promises lockstep with demos/workloads/inference/vllm-agg.yaml, which this PR bumped to 1.4.1; and a 1.2.x worker defaults its event plane to NATS, now removed — so the UAT serve phase runs a stale image with no event-plane backend. Fix: bump to 1.4.1.
🟠 F4 — UAT security-group configs still open only NATS 4222; the new TCP/ZMQ data plane is unopened (overlaps mchmarny's MAJOR). tests/uat/aws/cluster-config.yaml:75-78 and cluster-config-gb200.yaml:107-110 open 4222 ("Allow NATS…"); gcp/cluster-config.yaml:62-63 comment still says NATS 4222 is permitted. None touched by this PR, and no rule opens the new direct frontend↔worker TCP/ZMQ ports — so EKS inference-dynamo UAT either regresses or silently stops validating the SG topology the doc mandates. Fix: replace the 4222 rule with the confirmed 1.4.1 ports (#1836) and verify a request routes end-to-end.
🟠 F5 — Networking doc ships <PORT> placeholders + "TODO before merging" (overlaps mchmarny's MAJOR) — see inline comment on eks-dynamo-networking.md.
🟠 F6 — docs/user/component-catalog.md:33 still calls the event plane "NATS-backed" — the canonical catalog now contradicts the shipped ZMQ default. Fix: "ZMQ-based KV-cache event plane."
🟠 F7 — docs/user/validation.md:384-391 describes the ZMQ→NATS relay as current behavior and still says "Dynamo 1.2 defaults to TCP". Fix: ZMQ event-plane wording; bump 1.2→1.4.
🟡 Minor
- F8 —
pkg/evidence/cncf/scripts/collect-evidence.sh:2387(static here-doc) hardcodes "Supporting Services — NATS running for Dynamo's Kubernetes event plane" → a false claim ships in generated CNCF conformance evidence. - F9 —
docs/contributor/validator.md:736-742repeats the NATS-relay description. - F10 —
validators/performance/inference_perf_constraint.go:2761comment "…onto NATS" drifts from ZMQ reality (comment only). - F11 —
validators/performance/testdata/inference/dynamo-deployment.yaml:19-20anddynamo-deployment-gateway-epp.yaml:18-19were bumped to1.4.1but keep the NATS-relay header comments (same-file inconsistency). - F12 —
demos/cuj2-demo.md:213,252,253narrate the NATS event plane (lines 212/250 are correct — keep those). - F13 — leftover
<NEW_VERSION>placeholder in a chainsaw assert comment — see inline comment. - F14 — the exact-value regression test
@mchmarnyrequested (resolved dynamo recipe ==1.4.1) does not exist;TestOverlayVersionPinsMatchRegistryonly enforces the no-pin model. Fix: add apkg/recipetest assertingComponentRef.Version == "1.4.1".
🔵 Nitpick
- F17 — MD031 blank-line-before-fence — see inline comment.
✅ Confirmed non-issues (examined and cleared)
- Trailing newline dropped in
values.yaml—.yamllint.yamlsetsnew-line-at-end-of-file: disable; not a lint failure. values.yaml:15header already reads(v1.4.1)— an initial persona claim that it still said1.2.1was refuted against the file.- The NATS opt-in comments in
values.yaml:27-36are correct and intentional (NATS is now opt-in legacy) — keep. - Chainsaw multi-doc YAML integrity is fine after the StatefulSet removal (no dangling
---). - Runtime storageClass injection safely no-ops when
storageClassPathsis empty — only the F1 tests break, not runtime.
Tally: 🔴 2 · 🟠 5 · 🟡 7 · 🔵 1. Verified against source at 053a47a0.

Request changes: 1 MAJOR against 053a47a.
MAJOR: Resolve the unfinished networking contract before merge
The existing blocking thread remains unresolved at this head. The networking guide still contains a merge TODO and <PORT> placeholders in its probe, required security-group rules, and AWS command, while UAT still permits the removed NATS port. Operators with split system and GPU security groups cannot apply or validate the required TCP and ZMQ access.
Minimum correction: establish the exact 1.4.1 listener ports and directions, replace every placeholder with actionable rules and probes, and synchronize UAT and user guidance to that tested contract.

@mchmarny @njhensley F1–F13 are all addressed in the latest commit. The remaining blocker is F4/F5: the placeholder in eks-dynamo-networking.md and the NATS 4222 SG rules in the UAT cluster configs . these require a live 1.4.1 EKS cluster to confirm the actual TCP request-plane port via ss -tlnp . I don't have access to one. |

Re-review — multi-persona + adversarial meta-review
Method: parallel persona reviewers (supply-chain, docs & CI-DX, Dynamo domain) → a senior meta-review that independently re-derived each claim from the resolved code, ran the actual gates, and checked the upstream Dynamo docs.
Mode: delta re-review over 89db3978 (F1–F13 fixes) + 46b20ba7 (main merge). Head 46b20ba7.
Legend: 🔴 Blocker · 🟠 Major · 🟡 Minor · 🔵 Nitpick
Prior-feedback status
| Prior finding | Disposition |
|---|---|
🟠 <PORT> + "TODO before merging" |
✖️ Not addressed — still present; same doc now also carries a Blocker (MDX gate). |
| 🔵 MD031 blank line before fence | ◐ Reframed / worse — MD031 itself is cosmetic (repo has no markdownlint), but the same blockquoted fence now hard-fails the MDX safety gate. |
🟡 <NEW_VERSION> in chainsaw assert |
✔️ Addressed — now reads 1.4.1. |
Assessment
The core NATS→ZMQ change is well-executed — values.yaml cleanly drops the NATS block (leaving global.nats.install unset to inherit the chart default, with a good upgrade note), the registry scheduling/storage paths are fully removed, the chainsaw asserts correctly drop the NATS StatefulSet, the wording sweep is complete and consistent, and every 1.2.1→1.4.1 bump landed. But three merge-blocking issues remain (inline): two are CI-gate failures introduced by the fix commit + merge, and one questions the PR's central premise for the workloads the inference-perf validator actually deploys.
Additional finding (file not in this diff, so noted here rather than inline)
🟡 Minor — stale 4222 NATS ingress SG rules remain in UAT cluster configs. tests/uat/aws/cluster-config.yaml:72-78 and cluster-config-gb200.yaml:104-110 still open fromPort/toPort: 4222 ("Allow NATS from worker nodes and pods"); tests/uat/gcp/cluster-config.yaml:62 comments "NATS (4222) is already permitted." These are now unused, and — tied to the DYN_EVENT_PLANE and <PORT> findings — the ports the new direct TCP/ZMQ path needs may not be covered. Untouched by this PR; sweep-completeness gap. After the real port is confirmed, retire/relabel the 4222 rule and add the actual port(s).
Confirmed non-issues (examined, no action)
- dynamo-platform BOM entry itself is correct (
1.4.1, single kubernetes-operator image, zero NATS images). global.nats.installleft unset to inherit the chart default (false) — sound, with a clear upgrade/rolling-restart note.- Registry NATS
nodeSelectorPaths/tolerationPaths/storageClassPathsfully removed; the two deleted bundler tests were NATS-only. - Chainsaw asserts correctly remove the
dynamo-platform-natsStatefulSet. - NATS→ZMQ wording sweep complete; every remaining
natsmention is legitimate legacy opt-in or an upgrade note. - Smoke-test
DYN_EVENT_PLANE=zmq/DYN_REQUEST_PLANE=tcpis correct — and is exactly the override the validator workloads lack (see the Blocker). - Anchor/link hygiene OK; MD031 & trailing-newline are cosmetic (the real doc-gate failure is the MDX one).

Summary
Scope: within the PR's diff, issue #1836, or the explicit request to complete the staged placeholders.
Version target: 1.4.2. Patch on 1.4.1 fixing a real bug — Frontend/SGLang Runtime images left the NIXL library where dlopen couldn't find it, so Rust NIXL silently ran against non-functional stubs. Chart dependencies (grove alpha.12-rc1, kai-scheduler v0.13.4) are identical between 1.4.1 and 1.4.2.
Six findings below (five confirmed, one open decision) plus branch hygiene and out-of-scope notes. Inline comments carry the per-line detail and suggested diffs.
Branch hygiene (author-side, not code)
- Branch is
BEHINDmain by 33 commits, contains a merge commit (46b20ba7f) instead of a rebase. - 4 of 6 commits lack a
gpgsigheader; the other two (the first content commit and the merge commit) contain one — a header's presence was checked, not signature validity. - PR body still says "This is a draft... everything here is staged with
<NEW_VERSION>/<PORT>placeholders" — stale now that 1.4.1/1.4.2 are shipped.
Out of scope
docs/user/component-version-matrix.md#L36andvalidators/performance/inference_perf_constraint.go#L317still cite1.2.1— historical/citation references, not live pins.- Legacy NATS references in AWS/GCP UAT cluster config and KWOK scripts — untouched by this PR's diff.
Open decision
6. Grove alpha.8 → alpha.12-rc1 requires a two-step CRD migration if bumped
recipes/registry.yaml#L597 — not touched by this PR's diff (no inline anchor available for that reason), in scope via the explicit completion request. Two real choices:
- Keep
alpha.8and verify interoperability with Dynamo 1.4.2's operator, or - Bump to
alpha.12-rc1with the migration below.
The migration defect itself is confirmed, reproduced live on a test cluster: Helm and Helmfile both skip crds/ on helm upgrade — a plain chart bump to alpha.12-rc1 alone never installs the new clustertopologybindings.grove.io CRD, so the alpha.12 operator crash-loops on a plain no matches for kind "ClusterTopologyBinding" regardless. The ShortNamesConflict occurs specifically when the new CRD is applied before the obsolete one is deleted -- alpha.8's clustertopologies.grove.io CRD (kind ClusterTopology, shortname ct) is still present, and alpha.12-rc1's replacement reuses that shortname. The required ordered migration avoids it:
kubectl get clustertopologies.grove.io -A-- if any exist, stop for an explicit data migration before touching CRDs.- If zero exist, delete the obsolete CRD:
kubectl delete crd clustertopologies.grove.io. - Explicitly apply the alpha.12-rc1 chart's
crds/--helm upgradewill not do this for you. - Then upgrade the release. Scoped to Helm/Helmfile only -- Flux and Argo CD manage CRD lifecycle differently and need separate guidance if that deployer path is used. For a manual Helm 4 upgrade, pass
--force-conflicts(Helm 4's server-side apply otherwise conflicts on the operator-managed webhook cert Secret); AICR's generatedinstall.sh(pkg/bundler/deployer/localformat/templates/install-upstream-helm.sh.tmpl#L20-L28) already detects Helm 4 and adds this flag conditionally, so use the generated script where available instead of a bare manual upgrade.

kube-prometheus-stack's helm render was OOM-killed on the machine that last ran make bom-docs (signal: killed, "_No images extracted._" in the committed doc).

Resolves the open Grove version decision. v0.1.0-alpha.12-rc1 (what the dynamo-platform 1.4.x chart itself declares as a disabled internal dependency) was superseded by the final v0.1.0-alpha.12 release five weeks later; alpha.8 was never verified end-to-end against the 1.4.x operator. Verified live on aicr-gb300: upgraded from alpha.12-rc1 to alpha.12, applied the new podgangmaps.grove.io CRD and the updated podgangs CRD, and confirmed kai-scheduler still gang-schedules a real workload (Frontend + VllmDecodeWorker PodClique/PodGang) against the new operator. Documented the required CRD migration inline in registry.yaml, since it applies identically whether upgrading to alpha.12-rc1 or alpha.12. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>

- A broken file reference missing .rs and a comma between the two
cited source files.
- The Required Security Group Rules section header said "GPU -> system"
while two of its own three bullets said "system -> GPU" -- the
example aws ec2 commands below were already correct, so only the
prose was stale. Split into two explicit ingress statements matching
the actual bidirectional requirement.

- tests/uat/lib/phases.sh: bump the active inference UAT lane's
runtime pin from vllm-runtime:1.2.1 to 1.4.2 and set
DYN_EVENT_PLANE=zmq explicitly on both containers -- this lane was
missed in the earlier 1.4.2 sweep, so it still deployed a
pre-NATS-removal runtime against the post-removal operator. Also
applied the same fix to the two other DynamoGraphDeployment
manifests that were missed (pkg/evidence/cncf/scripts/manifests/
dynamo-vllm-agg.yaml, demos/workloads/inference/vllm-agg.yaml).
- recipes/components/dynamo-platform/values.yaml: the documented NATS
opt-out (--set global.nats.install=true) doesn't work -- the
generated install.sh has no --set passthrough. Replaced with the
actual required steps (edit the rendered values.yaml directly) and
added the scheduling/storage-class overrides a re-enabled NATS needs
now that AICR no longer targets it at bundle-generation time, plus a
PVC-retention note.
- docs/user/component-catalog.md: surfaced the Grove CRD migration in
a user-facing doc -- it was previously only a registry.yaml comment,
invisible to anyone following the generated install.sh (which has no
CRD-migration step for Helm/local-format installs; OwnsCRDs only
wires into the Flux deployer, and grove doesn't set it).
- docs/integrator/eks-dynamo-networking.md: stopped implying the
reachability probe (fixed ZMQ port only) validates the dynamic TCP
planes or the reverse direction; extended the ZMQ SG rule to cover
the dp_rank offset range instead of a single port; corrected the
workload-readiness/health timeout description (they're alternative
failure points, not a cumulative 15 min -- confirmed against
waitForDynamoDeploymentReady returning before the health phase runs).
- demos/cuj2-demo.md, pkg/evidence/cncf/scripts/collect-evidence.sh:
corrected the stale CRD count (6 -> the actual 9: DynamoCheckpoint,
PodSnapshot, and PodSnapshotContent were missing) and webhook count
(4 -> 5), both verified against a live 1.4.1 cluster. Stopped
asserting the KV-cache event-plane choice unconditionally in the
evidence summary -- it reflects this workload's configuration, not a
cluster-wide guarantee.
- docs/user/validation.md: dropped a stale "Dynamo 1.2" reference, and
restored a qualifying clause ("least-loaded routing does not consume
those events") that the NATS-wording cleanup had dropped, which had
left the KV-router claim reading as unconditional despite
least-loaded being the default router mode. The equivalent text in
docs/contributor/validator.md already had this qualifier correctly.

Rebasing onto origin/main (744faca, the DRA K8s-floor bump) produced a real content conflict in both golden fixtures -- main changed non-dynamo leaf hashes, this branch changed dynamo leaf hashes. Resolved by fully regenerating both with AICR_UPDATE_GOLDEN=1 against the rebased tree rather than picking one side, so both sets of changes are reflected correctly.

…migration path - docs/integrator/eks-dynamo-networking.md: the doc assumed Frontend always runs on a "system" nodegroup separate from Worker's "GPU" nodegroup. Not true for AICR's own supported paths: the performance validator deliberately co-locates every Dynamo component on one node cohort specifically to avoid cross-SG traffic drops (see the comment on applyInferenceWorkerScheduling), and UAT does the same. Only the demo workload actually splits Frontend (cpu-worker) from Worker (gpu-worker). Reframed the whole doc by role (frontend/router vs. worker) instead of fixed node-group names, and added an explicit "skip this doc if co-located" note up front. Also: the probe example lacked a toleration for the taint its target node group likely carries, and pointed at "<worker-pod-ip-or-svc>" even though the operator-generated worker Service only forwards the health port (9090), not 5557 -- confirmed against GenerateComponentService upstream. Fixed to require the Pod IP directly. Clarified that checking the response-stream listener immediately after Pod Running proves nothing, since it binds lazily on first request. Corrected the ZMQ port-range example: dp_rank is a --data-parallel-size dimension, not a per-worker-replica one, so standard AICR deployments (dp_size=1 by default) all use plain 5557 regardless of replica count. - docs/user/component-catalog.md: the Grove CRD migration said to apply "<chart>/crds/", but a generated bundle has no local chart checkout to point at. Replaced with the same helm-show-crds-piped-to-kubectl pattern already documented for k8s-aibom in this file's Upgrade Notes section, and moved the full instructions there (was crammed into the component table's compact cell). - recipes/registry.yaml: shortened the grove migration comment to point at the now-canonical docs/user/component-catalog.md instructions instead of duplicating a stale command. - PR body: corrected the --set global.nats.install=true guidance (the generated install.sh has no --set passthrough) and referenced the new Grove upgrade doc.

…g networking-doc gaps
- CRITICAL correction: the DYN_EVENT_PLANE default claim was wrong.
Checked the actual Rust source (resolve_event_transport_kind) at both
tags: v1.2.1 defaults to nats for etcd/kubernetes discovery, but v1.4.2
changed this to zmq for every backend. AICR's own docs/PR-body text and
the evidence-collection comment incorrectly stated the OLD (1.2.1)
behavior as if it still applied at 1.4.2. Corrected everywhere, and
added the real justification for the explicit DYN_EVENT_PLANE=zmq
pins: guarding against a *standing* DynamoGraphDeployment still running
the OLD 1.2.1 image, which relies on ITS OWN compiled-in (nats) default
regardless of what the platform upgrade does.
- recipes/components/dynamo-platform/values.yaml: added the standing-
workload risk to the upgrade note -- the NATS-removal rolling restart
only touches operator-managed specs, not an existing DGD's own image
pin, so a 1.2.1 workload can silently keep expecting a NATS server that
no longer exists unless its image and/or DYN_EVENT_PLANE are also
updated.
- docs/integrator/eks-dynamo-networking.md:
- Split the SG rules into Frontend<->Worker (only if split across SGs)
and a separate always-required Prometheus rule -- kube-prometheus-
stack is pinned to the system node group regardless of Frontend/
Worker placement, so it needed to stop inheriting the "skip if
co-located" framing.
- Fixed the reachability probe: workload namespace varies (dynamo-
workload for the demo, dynamo-system for a validator run) so it's
now a placeholder, not a hardcoded namespace; switched to a bare
tolerations:[{operator: Exists}] so it isn't limited to NoSchedule
when the target node group also carries NoExecute.
- Corrected the failure-symptom description: Frontend/Worker readiness
probes are local-only (confirmed against upstream's
component_worker.go) and don't exercise cross-pod networking, so a
pure SG block passes the ~10 min DGD-readiness gate and actually
surfaces at the separate ~5 min /v1/chat/completions health probe.
- pkg/evidence/cncf/scripts/collect-evidence.sh: the evidence summary
claimed a specific event-plane transport the collector never actually
inspects (it accepts whatever DynamoGraphDeployment already exists).
Reworded to state that neutrally.
- PR body: fixed the same DYN_EVENT_PLANE default claim, and added the
missing `sed -n '/^---$/,$p'` filter to the Grove CRD-migration command
(reproduced upstream: the unfiltered command fails on the `Pulled:`/
`Digest:` lines an OCI `helm show crds` writes to stdout).

… symptoms, fix Prometheus SG example - recipes/components/dynamo-platform/values.yaml + PR body: the upgrade note said to bump the runtime image "and/or" set DYN_EVENT_PLANE=zmq. Setting ZMQ alone leaves an older runtime under a newer operator -- exactly the version-skew class that caused the frontend discovery panic fixed in NVIDIA#1193, a broader hazard than just the event-plane default. Reworded: the image bump is required, the explicit ZMQ setting is defense in depth on top of it, not a substitute. - docs/integrator/eks-dynamo-networking.md: - Split the failure-symptom description by transport instead of treating "networking blocked" as one failure mode. Confirmed against upstream source: the TCP request/response plane failing breaks inference outright (Rust client returns connection failures as request errors, not process crashes -- so CrashLoopBackOff isn't actually a typical symptom), surfacing at the inference-perf validator's separate /v1/chat/completions health probe (up to ~5 min after normal DGD startup) since neither readiness probe exercises cross-pod networking. The ZMQ KV-event plane, by contrast, is deliberately best-effort/lossy upstream -- a dropped event costs routing-estimate freshness, not correctness -- and the default least-loaded router mode doesn't consume those events at all, so blocking 5557 alone will not fail the health probe; it needs its own reachability check. - Fixed the probe's namespace comment: inference-perf actually creates aicr-inference-perf-<run-id>, not dynamo-system. - Fixed the Prometheus SG example: it reused <frontend-sg-id> as the Prometheus target, which only happens to work when Frontend and Prometheus share AICR's system node group -- not guaranteed (the demo's Frontend runs on cpu-worker, a different group). Introduced a separate <prometheus-sg-id> and authorized both eligible orchestrator source SGs into it. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>
… the bundle
The upgrade guidance told operators to hand-edit a generated bundle's
values.yaml/cluster-values.yaml. Both are covered by the bundle's checksum
manifest. Reproduced end-to-end:
aicr bundle ... (no NATS) -> aicr verify: PASSED
hand-edit 017-dynamo-platform/values.yaml
aicr verify -> FAILED, exit 4, checksum mismatch
A modified bundle also invalidates any existing attestation's binding to
the original checksum digest.
Verified the actual fix works end-to-end: regenerating via
`aicr bundle --set dynamoplatform:global.nats.install=true` (plus
--set dynamoplatform:nats.podTemplate.merge.spec.nodeSelector.<key>=<value>
and nats.config.jetstream.fileStore.pvc.storageClassName for the scheduling/
storage overrides) produces a bundle that passes aicr verify cleanly.
Moved the full instructions to docs/user/component-catalog.md ("Upgrade
Notes" > dynamo-platform), matching the pattern already used for the Grove
CRD migration -- registry/values.yaml comments don't survive recipe
parsing and rendering, so bundle users never saw this guidance anyway.
Trimmed the values.yaml comment to a short pointer.

The nodeSelector/tolerations overrides for a re-enabled NATS on a tainted system node group were documented with scalar --set, which cannot represent a qualified label key containing a slash (e.g. eks.amazonaws.com/nodegroup -- exit 2, INVALID_REQUEST) and has no form for a tolerations list at all. --system-node-toleration alone does not reach NATS: only the operator's controllerManager gets the toleration, and nats.podTemplate.merge.spec.tolerations renders empty. Switch both to --set-json. Verified: rendered nats.podTemplate.merge.spec carries the qualified nodeSelector and the toleration, and aicr verify passes on the resulting bundle.

Summary
Coordinate the NATS removal with the Dynamo 1.4+ bump: pin
dynamo-platformto 1.4.2, dropglobal.nats.installand the NATS storage-class/node-scheduling paths, bump Grove to v0.1.0-alpha.12, and update NATS-specific test/doc/conformance references — Dynamo 1.4+ defaults the request plane to TCP and the KV event plane to ZMQ.Motivation / Context
Upstream Dynamo 1.4+ disables bundled NATS by default (ai-dynamo/dynamo#11951) because the request plane now defaults to TCP and the KV event plane to ZMQ.
dynamo-platform1.4.2 additionally fixes a NIXL loader-path bug in the Frontend and SGLang Runtime images.Fixes: #1836

Framed by role (frontend/router vs. worker), not by fixed node-group name, since AICR's own supported paths don't all split them the same way — the performance validator and UAT co-locate every component on one node group specifically to avoid this class of bug; only the demo workload's node placement actually needs the cross-SG rules.validators/performance/testdata/inference/dynamo-deployment*.yaml:DYN_EVENT_PLANE=zmqset explicitly on Frontend/worker/EPP containers.

helm upgradeaccepting the new default removes bundled NATS and dropsNATS_SERVERfrom operator-managed workload specs, which triggers rolling restarts — but that only restarts the operator-managed spec, not any standingDynamoGraphDeployment's own runtime image pin. A workload still running an older image (e.g.vllm-runtime:1.2.1, AICR's prior pin) withoutDYN_EVENT_PLANEset relies on that image's own compiled-in default, which wasnatsforetcd/kubernetesdiscovery at 1.2.1 (confirmed against upstream source; this only becamezmq-for-every-backend by 1.4.2) — so it can silently keep expecting a NATS server this chart just removed. Bumping any standing workload's runtime image to match the operator is REQUIRED before or alongside this platform upgrade (the same version-skew class that caused the frontend discovery panic fixed in #1193); settingDYN_EVENT_PLANE=zmqexplicitly is additional defense in depth, not a substitute for the image bump. Fresh bundle installs are unaffected. To opt out of the NATS removal instead, regenerate the bundle withaicr bundle --set dynamoplatform:global.nats.install=true(plus scheduling/storage overrides if needed) -- do not hand-edit a generated bundle'svalues.yaml/cluster-values.yaml, both are covered by the bundle's checksum manifest andaicr verifyfails closed on any modified file (reproduced: exit 4, checksum mismatch).
