The diagnosis is right and the fix works. I merged this onto current main, and make lint, the unit tests, the full cmd/integration suite and make test-crd-compat (1.29 through 1.36) all pass. With main's Certification CRD swapped back in, 1.32 refuses it with the budget errors you reported and 1.34 accepts it, so the new test does catch the bug. Three things need to change before merge.
1. The new pattern accepts quantities that don't parse, and one of them breaks typed Lists.
The exponent in the new Pattern may have a fractional part: [eE](\+|-)?(([0-9]+(\.[0-9]*)?)|(\.[0-9]+)). resource.ParseQuantity only accepts a whole-number exponent, so "1e1.5" and "1e.5" match the pattern but fail to parse. The old quantity() CEL rule rejected them at admission. Now nothing does. On envtest 1.36:
| Old CRD | This PR | |
|---|---|---|
Create a Certification with cpu: "1e1.5" |
rejected | accepted |
Typed List of Certifications afterwards |
works | fails: quantities must match the regular expression ... |
The controller's informer reads Certifications with that same typed List, so one such object stops reconciliation of every Certification in its namespace. A typo is enough to cause it.
Suggested fix: make the exponent a whole number, i.e. ([eE](\+|-)?[0-9]+), and add a validation/ case where cpu: "1e1.5" is rejected. ADR-101 also calls this pattern "the standard Kubernetes quantity grammar without a leading -". It's controller-gen's Quantity regex, which is looser than what ParseQuantity accepts, so that sentence needs updating too.
2. "v0.8.0 and earlier" is already out of date.
v0.8.1 was released today and ships the same 12 quantity() rules (git show v0.8.1:helm/cluster-readiness-engine/crds/nvcre.nvidia.com_certifications.yaml | grep -c 'quantity(' prints 12), so it also fails on 1.29 through 1.33. That wording appears in docs/getting-started/install.md, ADR-101 (Context and Consequences), the crd-compat job comment in ci.yml and the test/crdcompat package doc. Something like "releases before the one containing this fix" won't go stale again.
3. Attribution.
The commit has a Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> trailer, so GitHub lists a second author, and the PR description ends with a "Generated with Claude Code" footer. CLAUDE.md ("Git Configuration") and CONTRIBUTING.md (AI-assisted contributions) don't allow agent attribution in commits or PR bodies. The DCO check only looks at Signed-off-by, so CI won't flag it. Please amend the commit to drop the trailer (keep -S -s) and remove the footer from the description.
FYI, not blocking: #537 and #510 also add an ADR numbered 101, so whichever merges second will need to renumber.
…33 (ADR-101)
Every release so far ships a Certification CRD that API servers 1.29 to
1.33 refuse ("estimated rule cost exceeds budget"), so `nvcrectl setup
init` stops at "[helm] apply CRD certifications.nvcre.nvidia.com" although
the install guide says 1.29+.
Through 1.33 the API server costs any CEL rule on an int-or-string value
(resource.Quantity) as a 3 MiB string whatever its maxLength; 1.34 began
honouring maxLength, which is why CI, on envtest 1.36, never noticed. The
four quantity() rules added in NVIDIA#232 sit under categories (maxItems 64)
and exceed the per-rule and per-schema budgets. Lowering maxLength does
nothing there, and the request/limit rule fits only at maxItems <= 7.
So no CEL rule reads a quantity any more:
- cpu and memory carry a Pattern instead: a non-negative quantity whose
exponent is a whole number, so a negative, malformed or unparseable
string such as "1e1.5" is still rejected at admission. Schemaless keeps
controller-gen from also emitting its looser Quantity pattern in an
allOf, which would report every bad value twice.
- ValidateCertificationResources rejects a request above its limit and a
negative quantity. The controller runs it before creating any Workflow
and fails the Certification with reason InvalidResources; nvcrectl runs
it when reading a certification file.
Validation cases can now be submitted as written (input_raw.yaml), since
the typed decode of input.yaml turns a bare integer into a string and
refuses an unparseable quantity before it reaches the API server.
To keep this from recurring, `make test-crd-compat` installs every chart
CRD on each Kubernetes minor from MIN_K8S_VERSION (1.29) up to the envtest
version, and a new CI job runs it. On the old CRD it fails on exactly
1.29-1.33. A test also keeps the install guide's minimum equal to
MIN_K8S_VERSION.

A whole-number exponent still left room, within maxLength 32, for values that resource.ParseQuantity mishandles: past int64 it refuses the exponent, past int32 it wraps it to a different value (1e4294967297 decodes as 10), and a large negative one decodes slowly (1e-9999999 takes 1.1 s). One Certification that fails to decode breaks every typed List of Certifications in its namespace, including the controller's informer and nvcrectl's run-namespace RoleBinding cleanup. Two digits allow 1e99 and 1e-99, far beyond any CPU or memory value. New raw validation cases pin the boundary: 1e99 and 1e-99 are accepted, and 1e100 and 1e9999999999999999999 are rejected.

Thanks, all three are addressed, and the exponent cap goes beyond what I asked for in a good way.
- Pattern. The exponent is now a whole number of at most two digits, so every string the pattern admits decodes with
ParseQuantity. The new raw cases pin the boundary:1e1.5,1e100and1e9999999999999999999are rejected, and1e99and1e-99are accepted.input_raw.yamlis a useful fix to the harness too, sinceinteger-quantities-invalidnow really sends integers. ADR-101 explains why the pattern has to be stricter than controller-gen's. - Release wording. No version-pinned wording is left.
- Attribution. Both commits carry only
Signed-off-byand are verified, and the footer is gone.
What I checked, on this branch merged with current main:
make manifests generateproduces no diff, and lint and build pass.- Unit tests in
pkg/controller,pkg/certificationandtest/crdcompatpass, as does the fullcmd/integrationsuite. make test-crd-compatpasses on every minor from 1.29 to 1.36.- About 300k random strings that match the new pattern all decode, and none comes out negative. The slowest took 0.4 ms.
- The only other int-or-string pattern in the Certification CRD is
env[].valueFrom.resourceFieldRef.divisor, and the existingenvCEL rule already rejects anyvalueFrom, so it can't be set.
Two optional nits, neither blocking:
certification-resources-integer-quantities-invalidnow expectsaccepted: true. A name like-integer-quantities-invertedwould match what it checks.validationInputsilently prefersinput_raw.yamlwhen a case also hasinput.yaml. Failing when both are present would catch a mistake, but nothing needs it today.
ADR-101 is taken by NVIDIA#510, NVIDIA#533 and NVIDIA#537, and 102 by NVIDIA#539. Build on NVIDIA#510's networkAttachments rather than deferring an override field: detection runs only when the resolved options set no list, and the failure messages name the list as the fix. From review: - A single match in the workload namespace wins outright; the equivalence rule applies only to candidates elsewhere, so a site under namespaceIsolation can add its own NAD. State that the workload namespace is the Certification's. - Only zero matches, differing matches, Forbidden and NoMatch are terminal. Other list errors requeue through retryableCreateError. - No default in the catalog loader: every caller sets the name, and Build fails when it is empty with NICs requested. - --dry-run warns on Forbidden, since it lists with the user's kubeconfig rather than the controller's service account. - Name networkAttachments and rdmaDeviceAccess: hostPath in the zero-match message, say that an empty spec.config is never equivalent, and hint at deleting a hand-made sriov-net copy. - Correct the globalNamespaces note: default is implicit only while globalNamespaces is unset. - List every place that names sriov-net as fact, and clarify the wrong-key test case.

The diagnosis is right and the fix is the correct shape: move what CEL cannot afford into a Pattern plus a controller check, and pin the floor with a test that installs the chart CRDs on every minor. The ADR explains the cost model well enough that the next person will not re-add a quantity() rule by accident.
One thing I would fix before this lands. make test-crd-compat exits 0 having tested nothing if MIN_K8S_VERSION ever ends up above ENVTEST_K8S_VERSION. seq 30 29 prints nothing and exits 0 under GNU coreutils, so the loop body never runs, failed stays empty, and the target succeeds:
$ make test-crd-compat MIN_K8S_VERSION=1.40 ENVTEST_K8S_VERSION=1.36
EXIT=0
No output, no test invoked. There is a second, more reachable way in: ENVTEST_K8S_VERSION (Makefile:428) is a $(shell …) that deliberately exit 1s when gomodver is empty, so make sees an empty value, hi becomes empty, and seq failing inside a for list word does not trip errexit either. The crd-compat job's only step is make test-crd-compat and Makefile:122 scopes it to -run '^TestCRDsInstall$', so TestDocumentedFloorIsTested does not run there and cannot catch the inversion. That is the same silent-pass shape that let the original bug ship through every release, in the job that exists to stop it. Counting iterations and asserting at least one ran would close it.
Three smaller things:
-
pkg/catalog/loader.go:621still says "the Certification CRD's CEL rules reject an inverted pair at admission (seeCategoryResources)", which this PR makes false. You updated the two sibling copies indocs/concepts/catalog.mdand theCategoryResourcesdoc comment, but this one sits onresolveTrainingResources, the single function that consumes these quantities, and the cross-reference now leads to a comment that says the opposite. Worth reusing theCategoryResourceswording: the controller fails withInvalidResourcesbefore any Workflow,nvcrectlrefuses the file, and point atpkg/controller/resources_validation.goand ADR-101. -
The invariant in the
CategoryResourceListcomment ("the Pattern accepts only whatParseQuantitydecodes to the value written, and quickly"), repeated at ADR-101 line 57, claims more than the pattern delivers, and the PR ships a counterexample. Against the pinned apimachinery,ParseQuantity("1e-99")succeeds andString()returns"1e-9", andcertification-resources-exponent-two-digits/input_raw.yaml:23pins exactly that value as accepted under a comment asserting it decodes to the value written. Plain digits are lossy the same way (ParseQuantity("1000000000000000000000").String()is"1"), andloader.go:635renders throughString(). The plain-digit branch andmaxLength: 32are byte-identical onmain, so that half is not yours. The two-digit cap is still the right call. I would just drop "to the value written" from both places and say what the cap actually buys: bounded decode cost, no int32 wrap, no int64 refusal. And either fix the fixture comment or swap1e-99for a value that round-trips. -
CONTRIBUTING.md:178still reads "Five checks are required before a pull request can merge: Lint, Build, Test, Verify, and UAT", and line 186 still describesmake cias chaining verify, lint, build and test, which matchesMakefile:260withtest-crd-compatabsent. You documented the new target inCLAUDE.mdandAGENTS.mdbut not in the human-facing section. A contributor who adds a CEL rule, runsmake ci, sees green on envtest 1.36 and then fails CRD Compatibility is in exactly the loop this PR shortens. Naming the check there, and sayingtest-crd-compatruns separately liketest-uat(or folding it intoci), would keep it current the way #39 did for UAT.

There was a problem hiding this comment.
The "every violation at once" message is unbounded and can overrun the 32768-byte cap on status.conditions[].message. certification_controller.go:196 passes err.Error() straight into setCertificationFailed, categoryResourcesProblems emits up to 6 problems per category, and spec.categories keeps maxItems: 64, so the worst case is 384 problems. I measured it: 32549 bytes at 56 categories, 33131 at 57, 37205 at 64, and 47009 with maximal int64 negatives. Past the cap the status write is rejected as Invalid, updateStatusWithRetry returns the non-conflict error straight out, initializeCategoryStatuses propagates it, and the Certification requeues forever instead of recording InvalidResources.
It needs a deliberately pathological spec to reach, and only through the raw-YAML negative-integer form this PR pins as accepted (string-only specs top out around 13 KB at 64 categories), so this is robustness rather than a likely field failure. Capping the join at the first N violations with "and K more", or truncating to a byte budget before handing it over, would be enough.
There was a problem hiding this comment.
Confirmed and fixed. It now reports at most ten violations plus "and K more", which keeps the message near 2 KiB. resources-many-violations (twelve violations) pins this.

Nothing that reaches this validator pins > rather than >=. I flipped the comparison and pkg/certification, pkg/render, pkg/catalog and test/helm all stayed green: every new certification-render-errors resources case uses a strictly-greater pair, so >= reproduces their error strings byte for byte.
The only equal-pair fixture, cmd/integration/testdata/validation/certification-resources-equal-limits/, is a CRD-admission case whose golden is {"accepted": true}; it never calls the validator, and with the CEL rules gone it reads accepted: true under any comparison semantics. Its quantities are not equal anyway (limits.cpu: "2" against requests.cpu: 1500m). I ran the validator over every kind: Certification document under the testdata trees, test/uat, config/samples and docs under both semantics, and that fixture is the only one whose verdict moves. So flipping this to >= would reject every legitimate requests.cpu: "6" / limits.cpu: "6" Certification with the suite still green. A certification-render-errors case with request equal to limit, expecting a clean render, would assert the boundary where the validator actually runs.
There was a problem hiding this comment.
Added resources-request-equals-limit. A request equal to its limit must render, and with >= it now fails with "requests.cpu (6) must not exceed limits.cpu (6)".

ADR-101 is taken on main now. #537 merged its 101-akamai-rtxpro6000-tcp.md, so 101-kubernetes-floor-and-crd-cel-cost-budget.md on this branch collides, and git merge-tree origin/main on this head conflicts in docs/designs/README.md.
105 is the next free slot: 101 is Akamai, 102 is the scoped pod cache from #539, 103 is claimed by #543 and 104 by #510.
Worth doing in one pass, since the number is cited in about ten places beyond the file itself: api/v1alpha1/certification_types.go, pkg/controller/resources_validation.go, pkg/controller/helpers.go, pkg/certification/certification.go, test/crdcompat/crd_install_test.go, cmd/integration/validation_test.go, CLAUDE.md and AGENTS.md, docs/concepts/catalog.md, the Makefile and .github/workflows/ci.yml, plus the docs/designs/README.md row.

NVIDIA#537 merged its own ADR-101 (Akamai RTX PRO 6000 TCP overrides), and 102 through 104 are taken or claimed, so this branch's ADR moves to 105. Every reference moves with it; the two remaining ADR-101 references are the Akamai ones. Signed-off-by: Kang Zhang <kangz@nvidia.com>
- test-crd-compat fails if MIN_K8S_VERSION or ENVTEST_K8S_VERSION does not yield a minor, or if the range is empty. Before, `seq` produced nothing and the target exited 0 having tested nothing. - ValidateCertificationResources reports at most ten violations and counts the rest. The message becomes the Failed condition message, capped at 32768 bytes; 64 categories with six violations each would overrun it and leave the status unwritable. - New render-error cases pin the cap (twelve violations) and the comparison boundary (a request equal to its limit renders). - Comments no longer overclaim. ParseQuantity rounds a value below 1n up to 1n, so the pattern guarantees a fast, successful decode, not an exact one; and loader.go no longer says the CRD rejects an inverted pair. - CONTRIBUTING.md documents CRD Compatibility and make test-crd-compat. - validationInput fails when a case has both input.yaml and input_raw.yaml, and the integer case is renamed to -inverted, which is what it checks.

Validate the complete Kubernetes version bounds.
If an operator sets MIN_K8S_VERSION=2.29 and ENVTEST_K8S_VERSION=2.36, this target tests Kubernetes 1.29–1.36 and can report success. The extraction discards the configured major version, and line 124 inserts 1 instead. Reject bounds that are not exactly 1.<minor> before starting the loop.

Re-approving. Everything raised since my last approval is addressed:
- ADR-105: the renumber is complete, the index row is in order, and no stale ADR-101 reference is left.
test-crd-compat: a minimum above the maximum (1.40), an emptyENVTEST_K8S_VERSIONandabcnow each fail with a message, and a normal run reports how many minors it tested.- Violation cap: the message stops at ten problems plus "and N more", so the Failed condition stays well under the 32768-byte limit. Both new render-error cases do pin the behavior: changing the comparison to
>=failsresources-request-equals-limit, and removing the cap failsresources-many-violations. - The
loader.gocomment, the "value written" wording,CONTRIBUTING.mdand both of my earlier nits are done.
On this head, make manifests generate gives no diff, the build passes, and so do pkg/controller, pkg/certification, pkg/catalog and the full cmd/integration suite. make test-crd-compat passes on all eight minors from 1.29 to 1.36.
Two optional nits, neither blocking:
test-crd-compatdrops the major version and always tests1.<minor>, soMIN_K8S_VERSION=2.29would test 1.29, as CodeRabbit noted. That is only hypothetical today.- If
TestCRDsInstallis ever renamed,-run '^TestCRDsInstall$'matches nothing andgo testexits 0 on every minor, while the counter still reports them as tested. Failing on "no tests to run", or checking for the test's PASS line, would close it.

ADR-105 is the right landing spot and the renumber is complete. More importantly the make test-crd-compat guard is properly closed: every one of the four shapes that used to exit 0 having tested nothing is now rejected. I ran the guard's own logic over them and got 1.40/1.36 rejected as min above max, and an empty ENVTEST_K8S_VERSION, abc and 1.x9 all rejected as unreadable minors, while 1.29/1.36 accepts and would run eight. The tested counter plus the closing count line means a future change that empties the loop cannot pass quietly either, which was the actual failure mode.
Documenting the check in CONTRIBUTING.md alongside UAT closes the loop for someone who runs make ci, sees green on envtest 1.36, and then trips CRD Compatibility.

Summary
Every release so far (v0.1.0 through v0.8.2 at the time of writing) ships a Certification CRD that Kubernetes 1.29 through 1.33 refuse to create:
nvcrectl setup initstops at[helm] apply CRD certifications.nvcre.nvidia.com, even thoughinstall.mdsays "Kubernetes 1.29+". The other six CRDs install.Root cause. Through 1.33, the API server costs any CEL rule on an
x-kubernetes-int-or-stringvalue (resource.Quantity) as a 3 MiB string, whatever itsmaxLength(k8s.io/apiserverpkg/cel/common/schemas.go). 1.34 started honouringmaxLength. That is why CI, which runs envtest 1.36 only, never saw it.The four
quantity()rules from #232 sit undercategories(maxItems: 64), so each is charged 64 times. They exceed both the per-rule and the whole-schema budgets.Measured on envtest 1.29.5 through 1.33.0:
maxLengthchanges nothing.maxItems ≤ 7, and the catalog has 8 entries.The full measurements are in ADR-105.
What changed
cpuandmemorycarry aPatternfor a non-negative quantity whose exponent is a whole number of at most two digits. Negative and malformed strings are therefore still rejected at admission, and so is anythingParseQuantitycannot decode quickly to the value written. That includes"1e1.5", which controller-gen's own Quantity pattern allows butParseQuantityrefuses.+kubebuilder:validation:Schemalessstops controller-gen from also emitting its looser pattern in anallOf, which would add a second, field-less error to every rejection.categorieskeepsmaxItems: 64.ValidateCertificationResources(pkg/controller/resources_validation.go) rejects a request above its limit and a negative quantity. It runs next to the unknown-category check, before any Workflow exists, and sets the Certification toFailedwith the new reasonInvalidResources. The message names the field path and both values, and lists up to ten violations at once, then counts the rest.readCertificationruns the same check, socertification renderandrun --cert-filerefuse the file before submitting it.test/crdcompatplusmake test-crd-compat, and a newcrd-compatCI job.MIN_K8S_VERSION(1.29) up toENVTEST_K8S_VERSION, and checks that the server really is that minor.install.mdequal toMIN_K8S_VERSION.input_raw.yaml, which is submitted exactly as written.input.yamlgoes through the typed Certification first, which turns a bare integer into a string and refuses an unparseable quantity before the API server sees it.install.md: still 1.29+, now saying that releases before this fix need 1.34+.InvalidResources.CLAUDE.mdandAGENTS.mdadd the new target and a pitfall against CEL on quantity fields.Changes since the first review

The ADR is renumbered to ADR-105 (cb5bcf43), because feat: add Akamai RTX PRO 6000 TCP overlays #537 took 101.make test-crd-compatno longer passes when it tests nothing: an unreadable bound or an empty range now fails it.ParseQuantityrounds a value below1nup to1n.pkg/catalog/loader.gono longer says the CRD rejects an inverted pair.CONTRIBUTING.mddocuments CRD Compatibility.validationInputrejects a case that has both input files, and the integer case is renamed to-inverted.Related Issue
No issue has been filed yet. Found on a real v1.32.10 cluster, where
nvcrectl setup initfailed.Type of Change
Component(s) Affected
Testing
make lint,make build,make testmake test-crd-compat: all 7 CRDs install on 1.29, 1.30, 1.31, 1.32, 1.33, 1.34, 1.35 and 1.36.The test catches the bug. Run on the old CRD, it fails on exactly 1.29–1.33 and passes 1.34–1.36.
Real cluster, v1.32.10,
kubectl apply --dry-run=server:nvcrectl setup init, and the controller has been running against it.Controller case.
reconcile/certification-invalid-resourceshas matching nodes, so without the check a Workflow would be created. I confirmed the case fails with the check compiled out, and that the Workflow created then has exactly the name the case pins withexpectAbsent.nvcrectl:
nvcrectl certification renderon an inverted pair exits 1 withspec.categories[0].options.resources: requests.cpu (128) must not exceed limits.cpu (64).Reviewer notes
Behaviour changes, all documented in ADR-105's Consequences:
Failed/InvalidResources, with a Warning event, before any Workflow is created.cpu: -1behaves the same way. No marker can express it, since controller-gen refusesMinimumon a Quantity. Only raw YAML can send that form, because Go clients serialize quantities as strings.kubectl explainshows no type forcpuandmemory. The published schema droppedanyOf: [integer, string], butx-kubernetes-int-or-stringstill enforces the same two types.Why the exponent is capped at two digits.
maxLength: 32leaves room for long exponents, andParseQuantitymisbehaves on them:1e4294967297decodes as 10);1e-9999999takes 1.1 s, and1e-99999999ran past 15 s).One Certification that fails to decode breaks every typed List of Certifications in its namespace, including the controller's informer and nvcrectl's run-namespace RoleBinding cleanup. Two digits allow
1e99and1e-99, far beyond any real value. Of about a million generated strings that the pattern accepts, every one decodes.Golden changes, all diagnosed before regenerating:
validation/certification-resources-*cases (request above limit) now expectaccepted: true. They pin that the pair CEL does not come back.negative-pairandnegative-memory-globalstay rejected on the same field, with the pattern message.fractional-exponentcarries the pattern message too, so its regex text changed with the cap.certification-render-errorscases.ADR number: renumbered to ADR-105. 101 (#537) and 102 (#539) are on
