Multi-persona review — Approve with comments
Method: four independent persona reviewers (Correctness, Domain/Recipe-Architecture, Test-coverage, Operability/CI-DX), each finding then re-derived from the resolved code by an adversarial senior meta-reviewer. Anchored to d0b9f9f.
Legend: 🔴 Blocker · 🟠 Major · 🟡 Minor · 🔵 Nitpick
Overall
Tight, unusually well-reasoned PR. The load-bearing claim — deployment constraints merge last-wins by name with no max() (validation.go:98-184), so an *-any wildcard is the weakest position for a floor — is verified true; the placement rule holds for all 11 resolved queries; both regression controls demonstrably fire (the downgrade and wildcard-injection experiments were reproduced); and 575.57.08 matches the cited NVIDIA GPU Operator platform-support page verbatim. No blockers, and neither persona-level Major survives re-derivation — both reduce to Minor (inconsistent-but-safe / future-proofing).
The one item worth fixing pre-merge is the 🟡 placement-invariant symmetry gap (Service/Intent guarded only by the Any sentinel while criteria omit-to-"") — a two-line fix that matches the accelerator branch you already wrote.
Two 🟡 minors on files outside this diff (can't anchor inline)
🟡 Convention inconsistency — recipes/overlays/rtx-pro-6000-any.yaml:47 (and the 7 other *-any wildcards). Deployment.gpu-operator.version — a functionally identical floor with the same last-wins/no-max merge semantics — is declared on every accelerator *-any wildcard in the catalog and duplicated on leaves at the same value. This PR does the opposite for gpu-driver floors, banning them from wildcards. The old pattern is safe only because no leaf ever downgrades the wildcard value; the new leaf-only rule is stricter and safer, not wrong — but the catalog now holds two opposite conventions for two constraints with identical mechanics, which will confuse the next author. Worth one sentence scoping the rule, or noting the durable alternative: a max-merge for floor-typed constraints in mergeValidationPhase would make wildcard placement safe and retire the placement rule entirely.
🟡 User-facing behavior change, undocumented — docs/user/validation.md "Skip scenarios" (~line 517). Declaring the floor flips check-nvidia-smi from banner-presence (skip, exit 0) to fail-closed on the no-GPU-nodes / all-cordoned / all-busy / unparseable-banner paths (per #1995, validators/deployment/nvidia_smi.go). An operator running aicr validate against a saturated or drained RTX PRO 6000 cluster now sees a hard failure where they previously saw a skip — with no product regression behind it. The mechanism is in docs/contributor/validator.md, but the operator-facing page documents only the inference guards and says nothing about driver floors. The checklist's "N/A; no user-facing surface added" undersells this — suggest a short note there.
Confirmed non-issues (examined, not surfaced)
- CodeRabbit's "add a non-empty profile selection test" — genuinely unwritable and the downgrade scenario is structurally impossible: no
profiles:in any rtx-pro-6000 chain (selection is rejected at resolution),Deployment.*isn't a measurement Type so a profile value can't carry it, and profile-constraint collisions fail closed (profile_resolution.go:186-191). Your rebuttal is correct. - Golden hygiene — exactly the 5 rtx-pro-6000 deeper-leaf hashes changed in each golden, no resolver-wide drift;
rtx-pro-6000-anycorrectly did not move. The #2439 sequencing is standard rebase hygiene (CI's golden gate catches a stale regen). - check-nvidia-smi inheritance, the
found==0vacuity guard, floor value/source, and version parsing (08is base-10, not octal) — all verified sound.

Approving — standing multi-persona + adversarial-meta-review verdict was Approve with comments (🔴 0 · 🟠 0 · 🟡 4 · 🔵 2), unchanged since head d0b9f9f. No blockers; all open items are latent/future-proofing/docs and none gate merge. The load-bearing claim (deployment constraints merge last-wins by name with no max(), so an *-any wildcard is the weakest position for a floor) is verified, the placement rule holds for all 11 resolved queries, both regression controls fire, and 575.57.08 matches the cited NVIDIA GPU Operator page.

MAJOR: Cover the supported accelerator-only recipe path. This table calls the RTX PRO 6000 coverage exhaustive, but aicr recipe --accelerator rtx-pro-6000 --format json succeeds at this SHA with only base, monitoring-hpa, and rtx-pro-6000-any. That result retains check-nvidia-smi but has no Deployment.gpu-driver.version; the validator treats a missing floor as a no-op, so a working but below-minimum driver can pass this public path. This is the twelfth RTX PRO 6000 query omitted from the eleven test rows and contradicts the PR's all-queries claim.
Minimum correction: Ensure the accelerator-only result enforces at least 575.57.08 (or stops producing a deployable recipe) and add that exact query to the effective-value regression.

Fixed in 5b959a1. The rtx-pro-6000-any product fallback now declares Deployment.gpu-driver.version >= 575.57.08, while the existing EKS/LKE service x intent leaves retain the same floor so later overlays cannot weaken it. I also added the exact accelerator-only query to TestGPUDriverFloorEffectiveValue; it now resolves with both check-nvidia-smi and the driver floor. make qualify passes.

Thanks, Mark. I re-verified this path and need to correct my earlier reply.
The rtx-pro-6000 criterion is edition-collapsed: PCI IDs 2bb1 (Workstation), 2bb4 (Max-Q Workstation), and 2bb5 (Server), plus product-name normalization, all resolve to the same value. NVIDIA scopes 575.57.08 specifically to Server Edition, while driver 570.195.03 supports both Workstation editions and is supported by GPU Operator 25.10. Applying 575.57.08 through rtx-pro-6000-any would therefore reject a supported Workstation configuration.
Corrected in 4bd77056c: the generic accelerator-only recipe retains check-nvidia-smi but no Server-only driver floor. The >= 575.57.08 floor remains on the EKS and LKE service-specific leaves because AWS G7e and Akamai LKE both document Server Edition hardware. I added a negative regression for the accelerator-only query, updated the PR description, and reran make qualify successfully.
Please re-review 4bd77056c.

changed the title
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.

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 four provider-specific RTX PRO 6000 Blackwell Server Edition service x intent leaves. It also establishes the placement rule and regression tests needed to keep future floors from being silently weakened by overlay ordering.Related: #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 declared one, so the enforcement hook remained unused.This 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.Related work: #1995 (validator hook), #2402 (the same missing-requirement-expression pattern for Kubernetes versions), and #2439 (GPU stack version bump; not a functional dependency of this PR).
Type of Change
Component(s) Affected
cmd/aicr,pkg/cli)pkg/recipe)pkg/validator) — no validator change; the hook already existsImplementation Notes
Placement rule
Declare a floor on the maximal service x accelerator x intent leaf where the documented minimum is valid. A product-level accelerator wildcard may carry a fallback only when the minimum applies to every hardware variant normalized to that accelerator; repeat such a fallback on maximal leaves so intervening service overlays cannot weaken it. Never use
base, an accelerator-unbound overlay, or a floor with only one of service or intent wildcarded.FindMatchingOverlayssorts candidates by criteria specificity ascending, then merges each candidate's inheritance chain root to leaf. For example:The accelerator wildcard is applied before the service overlays. Deployment constraints merge by name with the later overlay winning and no version maximum (
pkg/recipe/validation.go), so an*-anyoverlay is the weakest position for a floor.The four declarations are therefore on these maximal leaves:
rtx-pro-6000-eks-trainingrtx-pro-6000-eks-inferencertx-pro-6000-lke-trainingrtx-pro-6000-lke-inferenceEach declaration is last for its own service x accelerator x intent query. The effective-value matrix verifies that all current deeper OS/platform leaves inherit it unchanged. No
gpuStackprofile exists in either chain, so there is no alternate-profile dimension for these recipes.Edition boundary
NVIDIA's documented
575.57.08minimum is explicitly scoped to RTX PRO 6000 Blackwell Server Edition. The concrete provider leaves are valid because AWS documents G7e as Server Edition and Akamai documents that LKE GPU Linodes use Server Edition.The
rtx-pro-6000criterion also represents Workstation and Max-Q Workstation editions. Both NFD product-name normalization and PCI discovery collapse all three editions to that value. NVIDIA's 570.195.03 supported-products list includes the two Workstation editions, and GPU Operator 25.10 supports that driver.For that reason,
rtx-pro-6000-anydeliberately carries no host driver floor. The accelerator-only recipe retainscheck-nvidia-smiand the GPU Operator floor, but does not impose the Server-only driver minimum. A generic host-driver floor needs either edition-specific criteria or a documented minimum valid for every edition represented by the criterion.Tests (
pkg/recipe/gpu_driver_floor_test.go)TestGPUDriverFloorEffectiveValue— 11 subtests assert the final effective floor for every concrete EKS/LKE Server Edition resolution and verify thatcheck-nvidia-smievaluates it.TestGPUDriverFloorEditionAmbiguousQueryHasNoFloor— asserts that the accelerator-only query retainscheck-nvidia-smiwithout inheriting the Server-only floor.TestGPUDriverFloorWildcardIsWeakestPosition— pins the ordering fact that requires maximal leaves to restate any valid wildcard fallback.TestGPUDriverFloorPlacementInvariant— rejects floors onbase, accelerator-unbound overlays, and partially wildcarded service/intent declarations; it also fails closed if the catalog contains no floor.What this does not close
#2438 should remain open because its motivating GKE cases still lack an attachable documented floor:
Sequencing
#2449 has merged, and this branch is current with
main. #2439 remains blocked and is not a functional dependency of this PR. Because #2439 also regenerates the same parity goldens, it must rebase and regenerate them from its final tree before merging after this PR.Testing
Both passed on the final branch.
make qualifycompleted with 84.2% coverage, zero lint issues, all 24 e2e suites passing, and no incompatible SDK or REST changes.The two parity goldens were regenerated from the final tree. Exactly five deeper RTX PRO 6000 leaf hashes change in each file;
rtx-pro-6000-anyis unchanged frommainbecause it carries no driver floor.Risk Assessment
The behavior change is limited to the four EKS/LKE Server Edition families and their descendants. On those recipes, a declared floor changes
check-nvidia-smifrom banner-presence validation to fail-closed validation when the version cannot be measured or is too old. The edition-ambiguous accelerator-only recipe retains its prior no-floor behavior.Checklist
