The Deployment.gpu-driver.version constraint shipped in NVIDIA#1995 and no recipe declared it, leaving the enforcement hook idle: a cluster with an arbitrarily old host driver validated green because check-nvidia-smi confirmed nvidia-smi ran and compared the version to nothing. Declare a floor for RTX PRO 6000 Blackwell Server Edition, which NVIDIA documents as requiring driver 575.57.08 or later. The floor is keyed to that documented minimum rather than to a shipped or test-validated version, which would prove sufficiency but not minimality. Placement matters because deployment constraints merge last-wins by name with no max comparison. Candidates resolve in ascending specificity, so an accelerator wildcard is applied before the service overlays it composes with -- making *-any the weakest position for a floor, not the broadest. The floor therefore lives on the four service x intent leaves, each of which is applied last for its own query and sits in the chain of every deeper OS/platform leaf. Add table-driven tests asserting the final effective floor for all 11 affected resolved combinations, an invariant test rejecting a floor placed on a wildcard, base, or accelerator-unbound overlay, and a test pinning the ordering fact the rule rests on.

🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win
Add at least one non-empty profile selection case.
The table always passes "" as the selection, so the selection parameter of resolvedDriverFloor is never exercised. Issue #2438 requires coverage for alternate profiles. A profile overlay that adds a same-name Deployment.gpu-driver.version constraint would downgrade the floor without any test failing.
Add a case that resolves an RTX PRO 6000 leaf with a real profile selection and asserts the same effective floor.

resolvedDriverFloor and hasDeploymentCheck each built the same recipe, so every subtest resolved it twice. Split into one resolve plus two pure accessors, and put ctx before t to match the usual Go parameter order. Also records why no non-empty profile selection is exercised: no overlay in the RTX PRO 6000 EKS or LKE chains declares a profile — only aks.yaml and gke-cos.yaml do anywhere in the catalog — and selecting a profile against a composition that declares none is rejected at resolution. A profile could not downgrade this floor even where one exists, because ProfileValue.constraints are validated as measurement paths at catalog load and Deployment is not a measurement Type.

Summary
Declares the first host GPU driver floor in the catalog —
Deployment.gpu-driver.version: ">= 575.57.08"on the four RTX PRO 6000 service x intent leaves — and establishes the placement rule and regression tests that make future floors safe to add.Fixes: #2438
Motivation / Context
check-nvidia-smigained aDeployment.gpu-driver.versionconstraint in #1995, with fail-closed semantics when a declared floor cannot be measured. No recipe ever declared one, so the enforcement hook has been built and idle since it landed.This is the consuming half. It is a validation contract, not a deploy gate: without a floor,
aicr validatecannot fail on an out-of-spec driver. It does not reject the recipe or stop Helm — that distinction separates it from #2402, where the chart's ownkubeVersioncauses Helm to refuse installation.Related: #1995 (the validator hook), #2402 (same missing-requirement-expression pattern, Kubernetes-version instance), #2439 (GPU stack version bump — merge that first, see Sequencing)
Type of Change
Component(s) Affected
cmd/aicr,pkg/cli)pkg/recipe)pkg/validator) — no validator change; the hook already existsImplementation Notes
The placement rule — the durable part of this change
Declare a floor on the maximal-leaf overlay for the affected service x accelerator x intent family. Never on an
*-anywildcard, never onbase, never on an accelerator-unbound service overlay.FindMatchingOverlayssorts candidates by criteria specificity ascending, then merges each candidate's full inheritance chain root to leaf. Resolved through the production path:The accelerator wildcard
rtx-pro-6000-anyis applied before the service overlays. Constraints merge by name with the later overlay winning and no max comparison (pkg/recipe/validation.go:140-172), so*-anyis the weakest position for a floor, not the broadest — the inverse of the natural intuition, and precisely the silent-downgrade path #2438 predicted.The four declaring leaves were selected by resolving all 12 rtx-pro-6000 queries rather than reading filenames. Each is the maximal leaf for its own query and sits in the chain of every deeper OS/platform leaf, so one declaration covers all 12 and nothing later can overwrite it.
No
gpuStackprofile exists anywhere in the EKS/LKE chains, so there is no alternate-profile dimension for these leaves. (Profile values cannot carry aDeployment.*constraint in any case:ProfileValue.constraintsare validated as measurement paths at catalog load, andDeploymentis not a measurementType.)The floor, and why this source and not the obvious one
Source recorded in a comment beside each declaration — NVIDIA GPU Operator platform support:
This is a product-level minimum: OS- and provider-independent, so it holds across the whole chain.
Google's per-accelerator numbers (L4/H100 >= 535, H200 >= 550, B200 >= 570) were deliberately not used. They sit under "GPUs on Ubuntu nodes -> Ubuntu driver compatibility", and all 14 AICR GKE overlays declare
os: cos. Applying them to COS leaves would assert a minimum neither Google nor NVIDIA has stated for COS.Likewise
HGX B200 >= 570.133.20is documented as a driver container version — the operator's driver image — so it does not transfer to host-managed leaves.Tests (
pkg/recipe/gpu_driver_floor_test.go)TestGPUDriverFloorEffectiveValue— 11 subtests asserting the final effective value for every affected resolved combination, plus thatcheck-nvidia-smiis present so the floor is not inert.TestGPUDriverFloorWildcardIsWeakestPosition— pins the ordering fact the rule depends on, so a resolver change surfaces loudly rather than silently downgrading floors.TestGPUDriverFloorPlacementInvariant— rejects any future floor on a wildcard,base, or accelerator-unbound overlay; fails closed if zero floors exist, so it cannot go vacuous.Both controls were demonstrated to fire. Injecting a lower
>= 550.00.00onrtx-pro-6000-eks-ubuntu-trainingfailed exactly the two inheriting rows with a last-wins diagnostic; moving a floor ontortx-pro-6000-anyfailed the invariant. Both reverted.What this does NOT close
The issue's headline example is not implemented, and #2438 should stay open:
R580.95.05is genuinely documented, but everygb300-*overlay is EKS. There is no GKE GB300 overlay to attach it to.Option D from the issue (matching a floor to the configured
driver.versionpin) is a different contract — rollout convergence, not minimum compatibility — and remains deferred.Sequencing
Merge #2439 first. Both branches regenerate the same two parity-golden files, and a merge-tree check confirms they conflict. After #2439 lands, rebase this branch and regenerate both goldens rather than hand-selecting conflict sides — they are derived files, and hand-resolving a hash produces a golden matching neither tree.
Testing
make qualifypassed on this branch, verified by log rather than exit code:QUALIFY_EXIT=0with theCodebase qualification completedsentinel, zero failure-shaped lines across 9,791 lines, 103 packages ok, coverage 84.2% (threshold 80%),golangci-lint0 issues., e2e "All tests passed!".Goldens regenerated: exactly 5 leaves moved in each file, all
leaf: sha256lines, all rtx-pro-6000.rtx-pro-6000-anycorrectly did not move, confirming the floor did not leak into the wildcard.Rebased onto current
main; the diff is byte-identical before and after, and the recipe/bundler golden tests still pass.Risk Assessment
Additive: four constraint declarations and one test file. The floor is far below the driver these families run today, so it is a guard against drift rather than a gate anything currently trips. Reverting is deleting four blocks.
Rollout notes: A declared floor changes
check-nvidia-smifrom banner-presence to fail-closed on the affected leaves — including when no node can be measured (no GPU nodes, all cordoned, all busy). That is intended per #1995: "a declared gate must not PASS unenforced." Operators runningaicr validateagainst a saturated RTX PRO 6000 cluster will now see a failure where they previously saw a skip.Checklist
