- Around line 35-36: Update the K8s.server.version constraint in all four GB300
GKE COS overlays to enforce the branch-specific minimums: accept versions at
least 1.34.3-gke.1318000 below 1.35.0, or versions at least 1.35.0-gke.2745000.
Keep the same constraint value across each overlay, including the workload
overlays that override inherited constraints.

Google Cloud A4X Max GKE minimum version 1.34.3-gke.1318000 1.35.0-gke.2745000
💡 Result:
<search_synthesis>
To use Google Cloud A4X Max compute instances in a GKE cluster, you must meet the following minimum GKE version requirements [1][2]: - For GKE version 1.35 or later: Use GKE version 1.35.0-gke.2745000 or later [1][2]. - For GKE version 1.34: Use GKE version 1.34.3-gke.1318000 or later [1][2]. These minimum versions are required to ensure support for essential features such as the R580.95.05 GPU driver (required for the GB300 GPUs in A4X Max bare metal instances) and Coherent Driver-based Memory Management (CDMM), which are enabled by default [1][3][4]. Always verify the latest official documentation when provisioning these clusters [1][2].

Enforce the branch-specific GKE build minimums in all four GB300 overlays.
pkg/version.Version.Compare does compare -gke.N build numbers. However, the current >= 1.34.3-gke.1318000 floor accepts unsupported 1.35 builds below 1.35.0-gke.2745000, such as 1.35.0-gke.500. Use the documented branch-specific compound constraint in these files:

The workload overlays repeat the constraint and override same-name inherited constraints, so correcting only either base overlay is insufficient.

MAJOR: Add the new public leaves to the stock-render golden
This change adds gb300-gke-cos-inference-dynamo and gb300-gke-cos-training-kubeflow, but the committed stock-render contract does not include either leaf. GOFLAGS=-mod=readonly go test ./pkg/bundler -run TestStockRenderParityGolden fails for both names, so the reviewed head cannot pass the required test and does not pin their rendered output.
Minimum correction: deliberately regenerate and inspect pkg/bundler/testdata/stock_render_golden.yaml for both new leaves, then rerun TestStockRenderParityGolden.
Evidence: the exact-head new leaf.
