Summary

• Adds ExternalMemorySpec type with URL (required) and SecretRef (optional) fields to operator/infra/api/v1alpha1/kapetool_types.go
• Adds External *ExternalMemorySpec field to MemorySpec (json:"external,omitempty")
• Reconciler branches in reconcileMemory: when external is set, skips Qdrant StatefulSet/Service/PVC provisioning and publishes the external URL into status.QdrantEndpoint; when external is nil, existing provisioning path is unchanged
• zz_generated.deepcopy.go and crds/kape.io_kapetools.yaml regenerated via make generate
• CRD reference doc updated with external field description and example YAML

Test plan

• TestToolReconciler_ExternalMemory_SetsReadyWithExternalURL — skips StatefulSet, sets QdrantEndpoint from URL, Ready=True/ExternalDatabase
• TestToolReconciler_ExternalMemory_WithSecretRef_SetsReady — same with SecretRef present
• TestToolReconciler_ProvisionedMemory_ExternalNil_StillProvisions — confirms provisioning path unchanged when external is nil
• All existing operator tests pass (go test ./operator/...)

Closes #12

Review — requesting changes (admin cannot use the request-changes API on own PR, so posting findings here)

Thanks for this — the overall structure is clean and tests pass locally (go build, go vet, go test ./operator/... all green after rebasing onto current main). Two findings against issue #12's acceptance criteria before this can merge:

Finding 1 — external.secretRef is declared but never wired (correctness gap)

ExternalMemorySpec.SecretRef is added to the type and CRD, and the field doc states:

"The operator injects the key value as the QDRANT_API_KEY environment variable in the handler pod."

But the implementation does not do this. reconcileExternalMemory (operator/controller/reconcile/tool.go) only publishes ext.URL into status.QdrantEndpoint — it never reads ext.SecretRef. The handler deployment builder (operator/infra/k8s/deployment.go) also has no reference to SecretRef; it only mounts the provisioned-path kape-tool-<name>-conn Secret. There are zero SecretRef reads in operator/controller/ or operator/infra/k8s/.

Issue #12 acceptance criterion: "set → skip provisioning, pass URL (and optional secret) into the handler's QDRANT_URL / API key env." The URL path works; the secret path is a no-op. A user who sets secretRef will get no error and no injected key — the field silently does nothing, which is worse than rejecting it.

Options: (a) wire SecretRef into the handler pod env (e.g. EnvVar with SecretKeySelector → QDRANT_API_KEY) in the external branch so the documented behavior is real, or (b) if this is deferred to a follow-up, drop SecretRef from this PR's API surface and remove the doc claim, and leave #12 open (do not close it) until the secret path lands.

Finding 2 — external URL has no format validation

ExternalMemorySpec.URL only carries +kubebuilder:validation:MinLength=1. There is no Pattern / CEL rule requiring a scheme. A value like "my-qdrant" (no http(s)://) would be accepted at admission and silently published into status.QdrantEndpoint, producing a broken handler config with no operator-side signal. The review brief calls out format validation as in-scope (reachability is out of scope, format is not).

Suggested: add +kubebuilder:validation:Pattern="^https?://.+"onURL(and mirror it incrds/kape.io_kapetools.yamlviamake generate), or a CEL x-kubernetes-validations` rule. Add a test case for a malformed URL asserting admission/reconcile rejection.

Notes on what is already correct

• Status field naming (QdrantEndpoint) is consistent across both branches — external path reuses the same field the provisioned path writes.
• No secret values leak into status: only the URL is published to status.QdrantEndpoint, and the URL is expected to be credential-free given the SecretRef design. ✅
• The rebase conflict in tool_test.go was resolved cleanly — duplicate helper definitions (findCondition, fakeConfigLoader, var _ ctrl.Result) were dropped since they already live in testhelpers_test.go on main; only the 3 new test functions were kept.
• Test coverage exists for both external-URL and provisioned paths. ✅

Verdict: FIX-ROUND-NEEDED — please address Finding 1 (wire SecretRef or drop it + leave #12 open) and Finding 2 (URL format validation + a negative test).
