Blocking on the destructive in-place upgrade path: removing the tracked legacy CRD deletes existing v1alpha2 InferencePool objects without migration.

[P1] Preserve or migrate existing v1alpha2 pools before deleting this CRD
This manifest is rendered into the tracked agentgateway-crds-post Helm release. On an ordinary upgrade Helm therefore deletes this removed template; Kubernetes then garbage-collects every inference.networking.x-k8s.io/v1alpha2 InferencePool across the cluster. The stable CRD is a different API group and schema (extensionRef/targetPortNumber versus endpointPickerRef/targetPorts), so the API server cannot convert or retain those objects. The PR body acknowledges this destructive path but labels the change non-breaking and low-risk, and there is no user-facing migration step. Please preserve the compatibility CRD for an explicit deprecation window or provide a tested migration or backup-and-restore path before making deletion part of a routine bundle upgrade.

Taken your first option in ecbef5d: the v1alpha2 CRD is now retained, not dropped, with native deprecated: true/deprecationWarning, helm.sh/resource-policy: keep + argocd.argoproj.io/sync-options: Delete=false,Prune=false, and the health-check assert restored — nothing is deleted on any deploy path.
Upstream GAIE v1.5.0 removes inferencepools.inference.networking.x-k8s.io. Dropping it from the vendored bundle prunes the CRD on any in-place upgrade and garbage-collects every v1alpha2 InferencePool cluster-wide. The stable v1 CRD is a different API group with an incompatible schema, so the API server cannot convert those objects. Retain the CRD under a deprecation window instead: - add native deprecated: true + deprecationWarning on the v1alpha2 version, so the API server warns on every client call - add helm.sh/resource-policy: keep and argocd sync-options Delete=false,Prune=false, applied now because both are read off the live cluster object at prune time and cannot be added retroactively - restore the health-check assert so all five installed CRDs are asserted Related to #1646 Signed-off-by: Varun Ramesh <varamesh@nvidia.com>

Summary
Refresh the vendored Gateway API Inference Extension (GAIE) CRD bundle from v1.3.0 to v1.5.0. Upstream v1.5.0 removes the experimental
inferencepools.inference.networking.x-k8s.io(v1alpha2); this PR deliberately retains it under an explicit deprecation window rather than dropping it, so no in-place upgrade deletes user data. Three references to the stable InferencePool CRD are retargeted.Motivation / Context
agentgateway v1.3.1 is built against GAIE v1.5.0, whose InferencePool schema adds spec.appProtocol (kubernetes.io/h2c selects HTTP/2; default HTTP/1.1). With the v1.3.0 schema installed, the API server prunes or rejects that field before the controller sees it, so the capability is silently unavailable. This is a missed capability, not a regression — the previous kgateway-train controller hardcoded HTTP/1.1.

config/crd/bases@ tag v1.5.0. The four CRDs upstream ships are byte-identical to upstream; the file's only divergence is item 2.inference.networking.x-k8s.io/v1alpha2InferencePool cluster-wide. The stable v1 CRD is a different API group with a different schema (endpointPickerRef/targetPortsvsextensionRef/targetPortNumber), so the API server cannot convert or retain those objects. Upstream itself served this CRD for five release lines (v1.0.0 → v1.4.0, ~7 months) before removing it.deprecated: true+deprecationWarning, so the API server warns on every client call touching it.helm.sh/resource-policy: "keep"andargocd.argoproj.io/sync-options: "Delete=false,Prune=false". Both are read off the live cluster object at prune time, so they only protect a cluster that actually installs v0.20.0/v0.21.0 — they cannot be added retroactively by the release that removes the stanza.validators/conformancerequiredCRDsare retargeted to the stable group — each is the only InferencePool assertion in its scope, and the stable CRD is what agentgateway v1.3.1 and dynamo-platform 1.2.1 actually consume.make bom-docs: no diff (CRDs carry no image references).Rollout (in-place upgrades): non-destructive. Nothing is deleted on any deploy path. The stable CRD gains
spec.appProtocol; the v1alpha2 CRD keeps serving existing objects and starts emitting a deprecation warning. Operators holding v1alpha2 InferencePools should migrate during the window:# detect kubectl get inferencepools.inference.networking.x-k8s.io -AMigration guide (detection and both cutover paths): https://github.com/kubernetes-sigs/gateway-api-inference-extension/blob/v1.5.0/site-src/guides/ga-migration.md
Nothing in AICR has ever authored a v1alpha2 InferencePool (
git log --all -S 'inference.networking.x-k8s.io/v1alpha2'is empty), and dynamo-platform 1.2.1 creates pools in the stable group, so the at-risk objects are hand-written or created by a co-tenant tool sharing these CRDs.Testing

Risk Assessment
No CRD is deleted and no existing object is affected, so there is no data-loss path in this release. The residual risk is deferred to the release that eventually removes the stanza, which is gated on the preflight described in Implementation Note 5.
