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.

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.

🟡 Minor — Placement-invariant only guards Service/Intent with the Any sentinel, but omitted YAML criteria store ""
Overlay criteria are stored raw from YAML: an omitted field becomes "", not the "any" sentinel (criteria.go:449-450; FillUnsetWithAny is never called on the store path). You correctly account for this on the accelerator check (criteria.Accelerator == "" || criteria.Accelerator == CriteriaAcceleratorAny, line 394) — but the wildcard disjunct above guards Service and Intent with only the == …Any form. A future accel-bound overlay that omits intent: (Intent=="") — e.g. a hypothetical rtx-pro-6000-eks spanning both intents — and declares a floor would pass this invariant, even though it sits at lower specificity than the intent leaves merged after it: exactly the silently-downgradable position this test forbids.
Fix: Mirror the accelerator branch:
if strings.HasSuffix(name, "-any") ||
criteria.Service == CriteriaServiceAny || criteria.Service == "" ||
criteria.Intent == CriteriaIntentAny || criteria.Intent == "" {Latent (no current floor is mis-placed), but cheap to close now while the guard is fresh.
| // intent leaves that carry the constraint, plus every deeper OS and platform | ||
| // leaf that must inherit it. A leaf missing from this table that gains a | ||

🟡 Minor — No completeness test asserts every rtx-pro-6000 family HAS a floor; a future service ships floor-less
TestGPUDriverFloorEffectiveValue is a fixed 11-row table and TestGPUDriverFloorPlacementInvariant only validates that declared floors are well-placed. Neither asserts that every rtx-pro-6000 service×intent family has a floor. The constraint comment argues the floor is "independent of node OS and cloud provider" — under that semantics, a future rtx-pro-6000-gke-inference / -aks / -oke overlay would silently ship with no host-driver floor (regressing to the pre-#2438 "validates green against an arbitrarily old driver" state) unless its author remembers to re-declare it, and nothing here would fail. All current families (eks/lke) are covered, so this is future-proofing, not a live defect.
Fix: Consider deriving the leaf set from store.Overlays (filter Accelerator == rtx-pro-6000, skip -any) and asserting each resolves the floor — that also subsumes the hand-maintained-table risk (a new leaf that breaks its base: chain would otherwise be unasserted).
| // eks-training, gke-cos), since a host driver minimum is a property of the | ||
| // GPU product and such an overlay cannot state one meaningfully — and a | ||
| // floor there outranks accelerator-bound wildcards applied earlier. | ||

🔵 Nitpick — Invariant doesn't forbid a deeper accel-bound leaf from declaring a lower floor
The invariant forbids only wildcard / service:any / intent:any / accelerator-unbound placement. A future deeper accel-bound leaf (e.g. rtx-pro-6000-eks-ubuntu-inference-dynamo, specificity 5) declaring a lower Deployment.gpu-driver.version would win via last-wins and pass this invariant — caught only if that exact combo is in the effective-value table. This is the inherent no-max limitation the PR already acknowledges (and deeper refinement is partly intended), so it's informational.
Fix: Worth one line in the header noting the residual, or folding into the max-merge alternative.

🔵 Nitpick — The ~24-line rationale comment is duplicated verbatim across all four overlays
The identical ~24-line rationale block (NVIDIA URL, #2438 placement reasoning, test names) is copy-pasted into all four leaf overlays. The value duplication is architecturally forced (that's the point of the placement rule), but if the NVIDIA minimum bumps or the doc URL moves, four sites must change in lockstep and a partial update leaves contradictory rationale. Acceptable given the declarative-overlay norm.
Fix: If you want to reduce drift, collapse to a one-line pointer plus a single canonical rationale in the referenced test file.

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
