In `@docs/user/component-catalog.md` at line 75, Update the Kubernetes version
wording in the Topology Updater documentation to remove the redundant “or
higher,” using either “K8s ≥ 1.32” or “K8s 1.32 or higher.”
Every recipe inherits nvidia-dra-driver-gpu from base.yaml, and the pinned chart declares kubeVersion: ">=1.32.0-0". Helm refuses the install below that, so 29 overlays declaring a lower K8s.server.version admitted clusters that pass every recipe-time check and then fail at `helm install`. recipes/overlays/ocp.yaml already carried >= 1.32 for exactly this reason; its comment recorded the diagnosis but the rest of the catalog was never reconciled. Every declaration is raised, not just base.yaml: constraints merge by name with the later overlay winning and no max comparison, so a leaf declaring ">= 1.30" silently overwrites a higher floor inherited from base. That is visible in the golden churn — the 16 leaves that moved are those inheriting a raised floor, while leaves declaring their own >= 1.34 or >= 1.32.4 were already clear and are unchanged. Adds a guard asserting no overlay or mixin declares a floor below the chart's, so the reconciliation cannot drift back. Control verified: reverting one leaf to 1.31 fails the guard. It also fails closed when no floors match, so it cannot go vacuous. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>
…known forms The guard used FindStringSubmatch, so only the first K8s.server.version declaration in a file was checked, and its regex matched only ">= 1.<minor>", so an exact pin or a range was skipped entirely. Both would admit clusters below the DRA chart's kubeVersion just as effectively. The original comment rationalised the second hole — "an exact pin or a range is a deliberate statement that should be reviewed on its own terms" — which is the wrong instinct for a guard whose only job is catching a future author deviating from the established shape. Now iterates every declaration and fails closed on any form it cannot interpret, naming the value and asking for either a >= floor or an extension to the guard. Controls verified: an exact pin of "== 1.30" fails as uninterpretable, and a second declaration of ">= 1.29" appended after a valid one fails as below the floor. Neither was caught before. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>
…ish the sweep Three gaps from review. The guard's value regex required double quotes, so a single-quoted or plain scalar was not misparsed but INVISIBLE — the declaration was never counted or checked. It now matches any YAML scalar style and trims quoting. The floor was a hardcoded constant that never read the registry, so a DRA chart bump raising kubeVersion would leave the guard green at a stale 1.32 despite a comment claiming the two move together. Replaced with an audited component/version/floor table plus TestDRAChartFloorAuditIsCurrent, following the ownsCRDs version-audit pattern. Both DRA components are enrolled: the earlier comment wrongly claimed no overlay disables the generic one, but ocp.yaml sets enabled: false and substitutes nvidia-dra-driver-gpu-ocp, so covering only the generic entry left the OCP chain unguarded. Controls verified: a single-quoted ">= 1.29" now fails where it was previously invisible, and pointing an audited entry at a version the registry does not pin fails the audit test. Also finishes the floor-reference sweep — the CLI reference constraint examples, the component-catalog Topology Updater note, the OKE L40S demo claim that the floor drops to 1.30, and two test comments naming the old kind 1.25 floor. Left alone: the GB200 table in demos/images/recipe.md claimed >= 1.28 before this PR while GB200 already required 1.34, so it is pre-existing drift rather than this change's to correct. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>
…AML text Decode each overlay and mixin into RecipeMetadata and evaluate every K8s.server.version constraint with the shipping parser and evaluator, so the guard no longer depends on YAML key order, quoting, or the expression's surface form. Also correct two stale comments: the MirrorDefaultKubeVersion note naming the old ">= 1.25" base floor, and the A100 GKE contrast with an H100 floor the recipe now shares.

…rsions The guard proved 'no too-old cluster satisfies this floor' by evaluating each declared expression against a fixed list of probe versions. That is sampling, and the production grammar supports arbitrary OR-of-AND ranges, so no finite probe list can cover it. '>= 1.32 || > 1.31.0 < 1.31.2' is a supported shape that passed the guard while the production evaluator accepts a Kubernetes 1.31.1 cluster that Helm's '>=1.32.0-0' rejects. Walk the parsed structure from constraints.ParseCompoundConstraint instead and prove the effective lower bound. An AND group's satisfying set is the intersection of its terms, so the group clears the floor as soon as any one term does; a compound's satisfying set is the union of its groups, so every group must clear it. Only >=, >, ==, and bare exact match place a lower bound; <, <=, and != place none. Anything else - an unparseable value, a major-only precision, an unknown operator - fails closed rather than being waved through. Symbolic proof was chosen over restricting the catalog to a simple '>= X.Y' form because it keeps the per-track GKE range expressions the parser already supports (see NVIDIA#1985) provable rather than banned, and it is exact where a grammar restriction is merely conservative. The defeating expression is kept as a permanent regression control in TestProveExpressionClearsFloor, with an adversarial control asserting the production evaluator really does admit 1.31.1 for it - so a prover bug that rejected everything cannot make the table green. Also corrects the comment attributing top-level constraint last-wins merging to mergeValidation in validation.go: RecipeMetadataSpec.Merge in metadata.go is what merges spec.constraints; mergeValidationPhase handles phase constraints.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
The per-declaration probe sweep can fail a declaration the prover accepts.
supported contains only 1.N.0 readings. A safe, patch-precision range therefore satisfies no probe. For example >= 1.34.3 < 1.35.0 clears proveExpressionClearsFloor, but 1.34.0 is below the lower bound and 1.35.0 is excluded by the upper bound. The sweep at Lines 386-402 then reports that no supported Kubernetes release satisfies the value and fails a correct floor. The GKE-shaped row at Line 428 escapes this only because its second alternative admits 1.36.0.
Global vacuity is already guarded by the checked == 0 check, so this sweep is the only source of the false failure. Add each term's own bound value to the probe set for the declaration under test.
♻️ Proposed fix: probe the declared bounds as well
Add the bound values of the parsed expression to the readings tried for that declaration:
parsed, err := constraints.ParseCompoundConstraint(decl.value)
if err != nil {
t.Errorf("%s (%s): %v", decl.file, decl.location, err)
return
}
+
+ // A range such as ">= 1.34.3 < 1.35.0" is satisfied by no "1.N.0"
+ // reading, so the declared bounds themselves must be probed too.
+ readings := supported
+ for _, group := range parsed.Alternatives {
+ for i := range group {
+ readings = append(readings, group[i].Value)
+ }
+ }
- for _, reading := range supported {
+ for _, reading := range readings {
satisfied, evalErr := parsed.Evaluate(reading)Update the final message at Lines 399-402 so it no longer claims the range 1.<floor> through 1.60 was the only set tried.

Summary
Raises the
K8s.server.versionfloor to>= 1.32on the 29 overlays that declared a lower one, so no recipe admits a cluster the pinned NVIDIA DRA driver chart will refuse to install on. Adds a guard so the reconciliation cannot drift back.Fixes: #2402
Motivation / Context
Every recipe carries a DRA driver.
base.yamldeclaresnvidia-dra-driver-gpu, and the one overlay that disables it —recipes/overlays/ocp.yaml— substitutesnvidia-dra-driver-gpu-ocpin its place. Both resolve to the same upstream chart, which declares:Helm refuses the install below that. So 29 overlays declaring a lower floor admitted clusters that pass every recipe-time check and then fail at
helm install. The recipe validates clean and the deploy breaks, which is the worst place for it to surface.This was already diagnosed once and never generalized.
recipes/overlays/ocp.yamlcarries>= 1.32with the comment:Same chart, same reasoning, one family. This reconciles the rest of the catalog.

Type of Change
Component(s) Affected
cmd/aicr,pkg/cli)pkg/recipe)pkg/defaultscomment correction)Implementation Notes
Why every declaration, not just
base.yamlRaising the base floor alone would not have worked. Constraints merge by name with the later overlay winning and no max comparison (
mergeValidation,pkg/recipe/validation.go:140-172), so a leaf declaring">= 1.30"silently overwrites a higher floor inherited from base.That is the same last-wins hazard documented for driver floors in #2438, showing up in a second issue — it is a general property of the constraint system, not a quirk of one constraint name.
The golden churn demonstrates it. Exactly 16 of 48 leaves moved: those inheriting a raised floor, including every
*-anywildcard. The leaves that did not move declare their own>= 1.34or>= 1.32.4, which already cleared 1.32 and were overwriting base's value anyway — so their effective constraint is unchanged.Overlays raised
29 declarations, all from a sub-1.32 value to

TestOverlayK8sFloorsClearDRAChartFloorasserts that no overlay or mixin declares a floor which admits a cluster below the chart'skubeVersion. It verified 95 declarations on this branch.It does not read the expression — it evaluates it. Each overlay and mixin is decoded into the typed
recipe.RecipeMetadata, and everyK8s.server.versionconstraint found inspec.constraints, in any validation phase, and in any profile value is parsed with the shipping parser (constraints.ParseCompoundConstraint) and evaluated against concrete sub-floor Kubernetes readings with the shipping evaluator.That is what makes the guard independent of how the constraint is written. Typed decoding removes YAML layout — key order, quoting style, comments, indentation — from the picture entirely. Evaluating rather than pattern-matching removes the expression's surface form: a compound
">= 1.32 || >= 1.29"begins with a safe floor but is still satisfied by 1.29.7, and an exact pin carries no>=prefix to match at all. Both are caught because both admit a sub-floor reading.The guard fails closed in three ways: on an expression the parser rejects, on an expression the evaluator cannot evaluate, and on an expression that no supported Kubernetes release satisfies (a typo rather than a floor). It also fails when zero declarations match, so it cannot go silently inert.
Coupling to the registry.
TestDRAChartFloorAuditIsCurrentholds an audit table recording, per DRA component, the chart version whosekubeVersionwas actually read. Both catalog DRA components are enrolled — OCP disables the genericnvidia-dra-driver-gpuand substitutesnvidia-dra-driver-gpu-ocp, so covering only the generic one would leave the OCP chain unguarded. If a pin inregistry.yamlmoves away from the audited version, the test fails until someone re-reads the chart'skubeVersionand updates the table. That is the point: the guard cannot sit green at a stale floor after a chart bump.Controls demonstrated. Each was applied to the tree, the guard was run, and the probe reverted:

Typed decoding also surfaced one declaration the text scan had never counted — 95 rather than 94.
What this does not do
The alternative from #2402 — making the
nvidia-dra-driver-gpucomponentRef conditional on server version so low-floor overlays omit it — is not implemented. It is more invasive and would leave those overlays without ComputeDomain/IMEX. It would only be worth revisiting if some family genuinely needs to support sub-1.32 clusters, which nothing in the catalog currently asserts.Sequencing
Merge #2439 first, then this, then #2446. All three regenerate the same two parity-golden files and will conflict pairwise. Resolve by rebasing and regenerating — these are derived files, and hand-picking a conflict side produces a golden matching neither tree.
Testing
golangci-linton./pkg/recipe/...and./pkg/defaults/...reports0 issues., captured to a file and gated on the exit code rather than piped.Golden regeneration was needed only for the constraint-value changes. The goldens are
leaf: sha256lines only — no structural changes — and the 16 moved leaves are fully accounted for above. The later guard rework is test-only and the comment corrections are comments, so neither moved the goldens; that was confirmed rather than assumed by re-running both parity tests withoutAICR_UPDATE_GOLDEN.The six guard controls are in the Implementation Notes table above. Each was applied to the working tree, run, and reverted, and the tree was confirmed clean afterwards.
make qualifypasses on the current head. Verified by reading the log rather than trusting the exit code: 9,800 lines, zero--- FAILlines, theCodebase qualification completedsentinel present, andQUALIFY_EXIT=0. That run was on the pre-rebase tree; the branch was then rebased ontoorigin/mainto pick up #2448 (an independentpkg/servertest addition, already green on main), after which the recipe guard and parity-golden tests were re-run green. Full qualify has not been re-run since the rebase.Risk Assessment
The change itself is 29 constraint values and one test. What makes it Medium is the user-visible effect: a cluster on Kubernetes 1.30 or 1.31 that previously resolved a recipe will now be rejected at generation.
That is the intended fix, not a regression — such a cluster was already broken, it just failed later and less legibly, at
helm install. Nobody loses a working configuration; they lose a configuration that only appeared to work until deploy time.Rollout notes: No cluster-side action. Anyone pinned below 1.32 who relied on recipe generation succeeding will now get a clear constraint failure naming the required version instead of a Helm
