Dependabot alerts were switched on for this repo today and reported 12 open findings. Ten are fixed here; the other two are addressed below. gRPC 1.83.0 -> 1.83.1, in all nine modules that require it. This is GHSA-vp52-pcj8-j9qc / CVE-2026-84304, heap memory exhaustion via HTTP/2 DATA frame fragmentation, affecting <= 1.83.0. It matters more than the version delta suggests: ingest/ is a gRPC listener deliberately exposed to the internet on :4317, so a remote OOM is reachable. mTLS narrows that to holders of a client certificate, which is why this was not an emergency, but the fix is one patch release away and there is no reason to carry it. golang.org/x/oauth2 0.21.0 -> 0.27.0 in deploy/operator, an indirect dependency (GHSA-6v2p-p543-phr9). enterprise/ was already past it at 0.36.0. npm cookie 0.6.0 -> 0.7.2, via an overrides entry rather than a dependency bump. @sveltejs/kit requires ^0.6.0 and still does at 2.70.3, the latest release, so there is no version of kit that resolves this on its own -- an override is the only route that does not involve waiting on upstream. Three incidental changes came out of `go mod tidy` and are not mine: genproto/googleapis/rpc moved forward as a transitive of the new grpc; pgx/v5 was reclassified from indirect to direct in enterprise/, which is simply correct, since audit.go and cmd/enterprise-auth import it; and the proto replace directive shuffled between require blocks at the same version. The twelfth finding, lru (GHSA-rhfx-m35p-ff5j), is not fixed and is not fixable here -- see the note in the pull request. It is CVSS 0, a Stacked Borrows soundness issue in IterMut, and reaching a patched version means tantivy 0.22 -> 0.26, which is a search engine migration rather than a dependency bump. Verified: all ten Go modules build, 40 test packages pass, the web app builds and svelte-check reports 0 errors across 288 files.
deploy/operator
A small controller-runtime Operator managing one CRD: Tenant
(cairnobs.io/v1alpha1). See internal/controller/tenant_controller.go's
doc comment for exactly what it reconciles and -- just as importantly --
what it deliberately doesn't (no ClickHouse calls, no Tantivy filesystem
access, no enterprise/internal/rbacstore wiring; those are
enterprise/internal/tenantprovision, still unbuilt).
Not kubebuilder-scaffolded
No kubebuilder/controller-gen binary was available in this
environment, so this package is hand-written rather than generated:
api/v1alpha1/zz_generated.deepcopy.go-- normallycontroller-gen objectoutput; hand-written here, covered byapi/v1alpha1/api_test.go's round-trip tests (mutate a copy, assert the original is untouched -- exactly the class of bug a hand-writtenDeepCopyis prone to).config/crd/cairnobs.io_tenants.yaml-- normallycontroller-gen crdoutput from the+kubebuilder:validation:*markers onapi/v1alpha1/tenant_types.go; hand-written here and only as strong as keeping the two in sync by hand. Validated by strict-unmarshaling it into the realk8s.io/apiextensions-apiserverGo type (see/deploy/README.md's verification section) -- catches YAML/structural mistakes, not a drift between the CRD's field descriptions and the Go doc comments.+kubebuilder:rbacmarkers oninternal/controller/tenant_controller.goare present as documentation/intent (matching kubebuilder convention) but were never run throughcontroller-gen rbac-- the actual ClusterRole is hand-written in/deploy/helm/cairnobs/templates/tenant-operator.yaml, kept in sync with those markers by hand, same caveat as the CRD above.
Layout
api/v1alpha1/ Tenant, TenantSpec, TenantStatus -- the CRD's Go types
internal/controller/ TenantReconciler -- see its doc comment
cmd/tenant-operator/ main.go -- manager setup, matches every other
service's cmd/<name>/main.go convention in this repo
config/crd/ hand-written CRD YAML (see above)
Building & testing
go build ./...
go vet ./...
go test ./...
Tests use sigs.k8s.io/controller-runtime/pkg/client/fake, not
envtest -- envtest needs a real kube-apiserver/etcd binary pair
(setup-envtest) not available in this environment. The fake client
exercises real reconcile logic (object CRUD, owner references, status
writes) but not anything a real apiserver does for you (admission,
garbage collection, watch-triggered re-reconciliation) -- see
internal/controller/tenant_controller_test.go's doc comment.
docker build -f Dockerfile -t cairnobs-tenant-operator . # context is deploy/operator/, not the repo root
