What does this PR do?

Prevents discoverable endpoints from overwriting Services owned by another workspace, including endpoints whose names normalize to the same Service name.

  • Admission uses a native cache index to check eligible endpoint names within the request namespace. Boolean/string discoverability, exposure rules, namespace fallback, unchanged-name updates and removal-only updates are covered.
  • Routing checks current Service ownership and protects updates and cleanup with object identity guards. Concurrent admissions can both pass before caches converge; reconciliation remains authoritative and preserves foreign Services. Duplicate-name diagnostics are deterministic.
  • Cluster-TLS routing validates each certificate Secret against its synchronized Service before publishing mounts. Missing certificates keep routing pending; foreign Secrets stay unchanged and cannot become generated workspace mounts. Each discoverable Service has its own certificate mount.
  • Failed routing can recover after a spec change through the new optional status.observedGeneration field. Failures remain terminal within a generation. Install updated CRDs before the updated controller so this field is retained.
  • Reconciliation cancellation reaches solver lookups and Service synchronization. External Go callers and RoutingSolver implementations must update the context-bearing GetSpecObjects signature.

RBAC: the webhook ServiceAccount gains cluster-wide DevWorkspace get/list/watch through its existing ClusterRoleBinding. This permits reading full workspace specs, including literal environment values and repository URLs, across namespaces. Conflict decisions remain namespace-scoped. The index reuses these permissions and adds no further RBAC.

The ADRs record ownership, certificate naming/readiness, indexing, generation recovery and context decisions. Load-test tooling and detailed campaign reports are preserved on a local branch for a later separate PR. No load-testing files are included in this PR.

What issues does this PR fix or reference?

Fixes eclipse-che/che#23231

Separate follow-ups: the backup CronJob nil-Workspace configuration panic predates this PR; its production fix is out of scope and the e2e workaround is documented. A stricter public endpoint-alias case reproduced an existing normalized Route/raw-name URL lookup mismatch. Its expected behavior needs team discussion. Neither issue has been filed yet, and neither production fix is included here.

Is it tested? How?

Use a cluster running this PR's controller and webhook image, with its updated CRDs installed first. The steps below use oc and disposable namespaces; certificate checks require OpenShift service-ca. Run the command blocks in the same shell. Commands marked as expected denials should fail admission.

Same-namespace conflicts and normalized names

Save this as workspace.yaml:

apiVersion: workspace.devfile.io/v1alpha2
kind: DevWorkspace
metadata:
  name: endpoint-test-1
spec:
  started: true
  routingClass: basic
  template:
    attributes:
      controller.devfile.io/storage-type: ephemeral
    components:
      - name: database
        container:
          image: quay.io/fedora/postgresql-12:latest
          endpoints:
            - name: postgresql-db
              targetPort: 5432
              exposure: internal
              protocol: tcp
              attributes:
                discoverable: true
          env:
            - name: POSTGRESQL_USER
              value: user
            - name: POSTGRESQL_PASSWORD
              value: pass
            - name: POSTGRESQL_ROOT_PASSWORD
              value: root
            - name: POSTGRESQL_DATABASE
              value: db

Create the first workspace and wait for readiness before trying a second:

review_ns="dwo-endpoints-$(date +%s)"
review_ns_other="${review_ns}-other"
oc create namespace "$review_ns"
oc create namespace "$review_ns_other"
oc create -n "$review_ns" -f workspace.yaml
oc wait --for=condition=Ready dw/endpoint-test-1 -n "$review_ns" --timeout=300s
sed 's/name: endpoint-test-1/name: endpoint-test-2/' workspace.yaml | oc create -n "$review_ns" -f -

Expected: the second create is rejected with discoverable endpoint 'postgresql-db' is already in use by workspace 'endpoint-test-1'. Repeat with a differently spelled endpoint that normalizes to the same Service name:

sed -e 's/name: endpoint-test-1/name: endpoint-test-2/' -e 's/name: postgresql-db/name: postgresql--db/' workspace.yaml | oc create -n "$review_ns" -f -

Expected: the same conflict denial; neither attempt creates endpoint-test-2.

Namespace isolation and discoverability updates

The same endpoint must work in another namespace:

oc create -n "$review_ns_other" -f workspace.yaml
oc wait --for=condition=Ready dw/endpoint-test-1 -n "$review_ns_other" --timeout=300s
oc get svc postgresql-db -n "$review_ns"
oc get svc postgresql-db -n "$review_ns_other"

Create a stopped, non-discoverable workspace in the first namespace, then try enabling discoverability with both encodings:

sed -e 's/name: endpoint-test-1/name: endpoint-test-2/' -e 's/started: true/started: false/' -e 's/discoverable: true/discoverable: false/' workspace.yaml | oc create -n "$review_ns" -f -
oc patch dw endpoint-test-2 -n "$review_ns" --type=json -p='[{"op":"replace","path":"/spec/template/components/0/container/endpoints/0/attributes/discoverable","value":true}]'
oc patch dw endpoint-test-2 -n "$review_ns" --type=json -p='[{"op":"replace","path":"/spec/template/components/0/container/endpoints/0/attributes/discoverable","value":"true"}]'

Expected: creation succeeds; both updates are denied with the same conflict reason. The stopped workspace creates no workspace pod.

An unchanged endpoint-name set and a discoverability removal must remain admissible. These probes use server-side dry-run to preserve the first workspace:

oc patch dw endpoint-test-1 -n "$review_ns" --dry-run=server --type=json -p='[{"op":"replace","path":"/spec/template/components/0/container/env/1/value","value":"changed"}]'
oc patch dw endpoint-test-1 -n "$review_ns" --dry-run=server --type=json -p='[{"op":"remove","path":"/spec/template/components/0/container/endpoints/0/attributes/discoverable"}]'

Expected: both succeed without persisting changes.

Foreign Service protection and routing recovery

Use a standalone routing object to exercise reconciliation independently of admission and workspace startup. Create a foreign Service and save its contents:

oc create service clusterip review-foreign --tcp=8080:8080 -n "$review_ns"
oc get svc review-foreign -n "$review_ns" -o yaml > foreign-service-before.yaml
oc create -n "$review_ns" -f - <<'YAML'
apiVersion: controller.devfile.io/v1alpha1
kind: DevWorkspaceRouting
metadata:
  name: review-routing
spec:
  devworkspaceId: review-routing
  routingClass: cluster
  podSelector:
    devworkspace_id: review-routing
  endpoints:
    database:
      - name: review-foreign
        targetPort: 8080
        exposure: internal
        protocol: tcp
        attributes:
          discoverable: true
YAML
oc wait -n "$review_ns" dwr/review-routing --for=jsonpath='{.status.phase}'=Failed --timeout=120s
oc get dwr review-routing -n "$review_ns" -o yaml

Expected: routing fails with an ownership conflict and status.observedGeneration matches metadata.generation. Rename the endpoint on the same routing object:

oc patch dwr review-routing -n "$review_ns" --type=json -p='[{"op":"replace","path":"/spec/endpoints/database/0/name","value":"review-recovered"}]'
oc wait -n "$review_ns" dwr/review-routing --for=jsonpath='{.status.phase}'=Ready --timeout=120s
oc get dwr review-routing -n "$review_ns" -o yaml
oc get svc review-foreign -n "$review_ns" -o yaml > foreign-service-after.yaml
diff -u foreign-service-before.yaml foreign-service-after.yaml

Expected: the routing keeps its UID, advances generation, reaches Ready with matching observed generation, and creates review-recovered. The foreign Service remains identical. Cluster routing creates no public Route/Ingress.

Per-Service certificates and foreign Secrets (OpenShift)

Switch the recovered routing to TLS:

oc patch dwr review-routing -n "$review_ns" --type=merge -p='{"spec":{"routingClass":"cluster-tls"}}'
routing_generation=$(oc get dwr review-routing -n "$review_ns" -o jsonpath='{.metadata.generation}')
oc wait -n "$review_ns" dwr/review-routing --for=jsonpath='{.status.observedGeneration}'="$routing_generation" --timeout=120s
oc wait -n "$review_ns" dwr/review-routing --for=jsonpath='{.status.phase}'=Ready --timeout=120s
oc get dwr review-routing -n "$review_ns" -o yaml
oc get svc,secret -n "$review_ns"

Expected: after service-ca issues certificates, status.podAdditions contains the aggregate mount at /var/serving-cert/ and a distinct discoverable mount at /var/serving-cert/review-recovered/. Each certificate Secret's originating Service name/UID annotations and Service owner reference match its Service. Volumes project only tls.crt and tls.key.

Check that an unrelated Secret cannot become a workspace mount:

oc create secret generic review-unrelated -n "$review_ns" --from-literal=marker=keep-me
oc get secret review-unrelated -n "$review_ns" -o yaml > foreign-secret-before.yaml
oc patch dwr review-routing -n "$review_ns" --type=json -p='[{"op":"replace","path":"/spec/endpoints/database/0/name","value":"review-unrelated"}]'
oc wait -n "$review_ns" dwr/review-routing --for=jsonpath='{.status.phase}'=Failed --timeout=120s
oc get dwr review-routing -n "$review_ns" -o yaml
oc get secret review-unrelated -n "$review_ns" -o yaml > foreign-secret-after.yaml
diff -u foreign-secret-before.yaml foreign-secret-after.yaml

Expected: routing fails certificate validation, publishes no Pod additions, and leaves the Secret unchanged.

Cleanup

Delete both namespaces and wait until namespace finalization removes all workspace, routing, Service and storage fixtures:

oc delete namespace "$review_ns" "$review_ns_other" --wait=true --timeout=300s
oc get namespace "$review_ns" "$review_ns_other"

Expected: both namespaces are NotFound. This fixture requests ephemeral workspace storage.

Summary by CodeRabbit

  • New Features
    • Discoverable endpoints now receive dedicated Services, with admission checks that detect conflicting endpoint names within a namespace.
    • TLS and web-terminal routing waits for valid serving certificates before reporting readiness.
  • Bug Fixes
    • Routing failures can recover after a spec change, while failures for the current spec remain terminal.
    • Service conflicts no longer overwrite or delete Services belonging to other workspaces.
    • Endpoint and certificate errors are reported more reliably, and cancellation is respected during reconciliation.

@akurinnoy is there a reason for implementing duplicate endpiont detection in both the webhook and the GetDiscoverableServicesForEndpoints function?

While the webhook prevents the DevWorkspaces (which will cause endpoint conflicts) from being created, the controller checks other cases:

  • two workspaces created simultaneously - both of them may pass the webhook validation
  • services can be created from other sources
  • old workspaces, created before this validation

Is this the answer to your question?

Btw, while looking at this method, I noticed it’s also used in che-operator here:

che_routing.go

objs.Services = solvers.GetDiscoverableServicesForEndpoints(routing.Spec.Endpoints, workspaceMeta)

Just wanted to give a heads-up that we’ll likely need to update there as well.

@akurinnoy : I ran your claude skill /ok-pr-review and it revealed this finding. Do you think it's a valid use case?

The webhook validation has a logic error that causes it to reject valid workspace creations. Currently, if the current workspace has a discoverable endpoint named X, and another workspace has any endpoint (discoverable OR NOT) named X, we reject it.

Steps to reproduce

  • Create workspace A with a non-discoverable endpoint named "postgresql"
oc create -f - <<EOF
apiVersion: workspace.devfile.io/v1alpha2
kind: DevWorkspace
metadata:
  name: workspace-a
  namespace: test-namespace
spec:
  started: true
  routingClass: basic
  template:
    components:
      - name: postgresql
        container:
          image: quay.io/fedora/postgresql-12:latest
          endpoints:
            - name: postgresql
              targetPort: 5432
              exposure: internal
              protocol: tcp
EOF
  • Create workspace B with a discoverable endpoint named "postgresql" (gets rejected)
oc create -f - <<EOF
apiVersion: workspace.devfile.io/v1alpha2
kind: DevWorkspace
metadata:
  name: workspace-b
  namespace: test-namespace
spec:
  started: true
  routingClass: basic
  template:
    components:
      - name: postgresql
        container:
          image: quay.io/fedora/postgresql-12:latest
          endpoints:
            - name: postgresql
              targetPort: 5432
              exposure: internal
              protocol: tcp
              attributes:
                discoverable: true
EOF

Do you think Workspace B should be allowed because Workspace A's endpoint is NOT discoverable and doesn't create a service named postgresql?

📝 Walkthrough

This PR adds indexed admission checks for discoverable endpoint conflicts, ownership-aware Service synchronization, and routing recovery based on observed generation. It also validates serving certificates before TLS routing becomes ready and adds tests and deployment schema updates for these changes.

Changes: Discoverable endpoint routing

Layer / File(s) Summary
Indexed endpoint conflict admission
webhook/workspace/..., pkg/webhook/cluster_roles.go, webhook/workspace/handler/testdata/*, adr/2026-10-07-discoverable-endpoint-index.md
Registers a namespace-scoped field index for normalized discoverable endpoint names. Admission checks eligible endpoint additions against other workspaces and returns errors for missing namespaces or lookup failures. Tests cover index lifecycle and admission rules.
Discoverable Service generation and solver contracts
controllers/controller/devworkspacerouting/solvers/*, controllers/controller/devworkspacerouting/solver_client.go, pkg/common/naming.go, adr/2026-10-08-discoverable-service-certificates.md
Solvers pass context and client inputs to discoverable Service lookup. The lookup rejects reserved or duplicate normalized names and conflicting existing Services. TLS solver mounts use per-Service paths, and long certificate volume names use a hash-derived name.
Ownership-guarded Service synchronization
pkg/provision/sync/*, pkg/library/kubernetes/provision.go, controllers/controller/devworkspacerouting/sync_services.go, controllers/controller/devworkspacerouting/*context_test.go, adr/2026-10-08-routing-service-ownership.md, adr/2026-10-12-routing-solver-context.md
Routing and discoverable Services use guarded ownership checks and authoritative reads when configured. Service creation races retry; updates preserve cluster-assigned identity fields. Service operations receive the caller context, and cancellation or deadline errors propagate from reconciliation.
Routing recovery and certificate readiness
apis/controller/v1alpha1/devworkspacerouting_types.go, controllers/controller/devworkspacerouting/*, pkg/provision/workspace/routing.go, pkg/library/status/*, deploy/.../devworkspaceroutings*, adr/2026-10-12-*
Routing status records observedGeneration. A failed routing retries after a spec generation change. TLS routing checks serving-certificate Secret identity and TLS data before readiness; pending certificates requeue, and invalid certificates fail routing. Deployment schemas include the new status field.

Merge Risk: 🟡 Moderate · up to 413b5

The change prevents discoverable endpoints from taking over Services that belong to other workspaces. However, a workspace whose inlined or async-storage Service shares its name with an unlabeled Service from another source can retry indefinitely instead of reporting a clear conflict. That workspace can stay stuck while preparing. Routing the remaining Service sync paths through the guarded ownership check should be resolved before merge, or the gap explicitly accepted. The copyright-header fix is minor.

Security architecture risk: 🟡 Moderate · up to 413b5

The changes strengthen protection against conflicting Services and inappropriate certificate mounts, but also give the webhook access to complete workspace specifications across the cluster. That intentionally broadens the consequences of webhook compromise. Recovery and certificate lifecycle coverage remains incomplete; no direct cross-namespace admission bypass was established.

Retained concerns

  • Medium · security · observed: The endpoint index introduces cluster-wide access to complete DevWorkspace objects for the webhook identity. Compromise of the webhook process or its credentials would newly expose workspace specifications across namespaces, including literal environment values and repository information. This is an intentional authority expansion, not evidence of an admission caller obtaining that access. Read-only verbs and namespace-scoped conflict decisions are important countercontrols, but do not narrow the credential's cluster-wide confidentiality impact.
Security review details

Security Blast Radius

  • inferred — The maximum independently exposed confidentiality scope of the new permission is all DevWorkspace objects in the cluster. The relevant prerequisite is control of the webhook process or its ServiceAccount credentials, not merely permission to submit a workspace in one namespace. No new write capability follows from this rule.

Security Findings and Attack Paths

  • inferred — A webhook compromise could use the newly authorized Kubernetes reads to retrieve other namespaces' workspace specifications. This conditional attack path explains the authority-expansion concern; neither a webhook compromise mechanism nor direct cross-namespace disclosure through an admission response was established.

Trust Boundaries and Controls

  • observed — Workspace-controlled endpoint claims cross into privileged Service management only after namespace-local admission checks and reconcile-time ownership checks. Concurrent admissions can both pass, but live Service reads and synchronization guards prevent treating the admission cache as an ownership reservation.

Resilience and Maintainability Implications

  • observed — The new conflict-failure branches can retain prior routing payload fields, but the inspected workspace consumer does not consume those fields while routing is Failed. The controller also retries legacy failures with zero observedGeneration while the workspace consumer treats zero as terminal. These are recovery-contract limitations, not an established security bypass; downstream recovery ordering remains unverified.

Hardening Proposals

  • proposed — Treat the webhook identity as a cluster-wide sensitive-data reader. If deployment requirements permit, evaluate namespace-scoped operation or a separately authorized endpoint-only index to reduce that authority. Reducing cached fields alone would not narrow the ServiceAccount's API permissions.

Full details: Linked Issues check

Explanation

Issue [#23231] requires that identical discoverable endpoint names do not leave workspaces stuck in routing. The webhook now checks eligible, normalized endpoint names within the request namespace and rejects a conflicting request. Routing also performs authoritative Service ownership checks, including concurrent-admission races, and preserves foreign Services. The implementation allows the same endpoint name in different namespaces. Tests cover same-name conflicts, normalized names, namespace isolation, routing recovery, and foreign-Service protection.

Full details: Out of Scope Changes check

Explanation

The changes remain connected to [#23231]. Admission indexing and RBAC support namespace-scoped conflict detection. Service identity guards prevent the controller loop and foreign-Service changes. Generation recovery, certificate validation, context propagation, CRD updates, tests, and ADRs support safe routing behavior and its deployment. The described load-test tooling is not included. No unrelated production change is demonstrated.

In
`@controllers/controller/devworkspacerouting/devworkspacerouting_controller.go`:
- Around line 128-133: The code sets workspaceMeta.DevWorkspaceName =
instance.Name but must use the parent DevWorkspace's name from
instance.OwnerReferences; update the DevWorkspaceMetadata population so
DevWorkspaceName is assigned from the owner reference whose Kind (or
APIVersion+Kind) indicates the parent DevWorkspace (e.g., iterate
instance.OwnerReferences, find ownerRef.Kind == "DevWorkspace" and use
ownerRef.Name), and fall back to instance.Name only if no such ownerRef exists;
change the assignment near workspaceMeta (DevWorkspaceMetadata,
workspaceMeta.DevWorkspaceName) to use that ownerRef-derived name.

In `@controllers/controller/devworkspacerouting/solvers/common_test.go`:
- Around line 16-27: Reorder the import block in common_test.go into three
groups with blank lines between them: (1) standard library (e.g., "testing"),
(2) third-party and Kubernetes packages (e.g.,
"github.com/stretchr/testify/assert", "k8s.io/api/core/v1" as corev1,
"k8s.io/apimachinery/pkg/apis/meta/v1" as metav1,
"k8s.io/apimachinery/pkg/runtime",
"sigs.k8s.io/controller-runtime/pkg/client/fake",
"sigs.k8s.io/controller-runtime/pkg/log/zap"), and (3) project-local imports

controllerv1alpha1 and
"github.com/devfile/devworkspace-operator/pkg/constants"); insert single blank
lines between these groups and then run 'make fmt' to apply formatting.

In `@webhook/workspace/handler/validate_test.go`:
- Around line 105-124: The test currently asserts a ServiceConflictError when
validateEndpoints (on WebhookHandler) is called with a workspace and a
deletingWorkspace (created via setupWorkspace) that has DeletionTimestamp set;
update the test so it reflects webhook behavior that ignores
deletion-timestamped workspaces: call handler.validateEndpoints(context.TODO(),
workspace) and assert no error (i.e., expect nil) instead of asserting
Error/ErrorAs for *solvers.ServiceConflictError, and remove or replace the
subsequent checks for conflictErr.EndpointName/WorkspaceName accordingly so the
test verifies that deletion-timestamped workspaces do not cause conflicts.
- Around line 16-31: Reorder the import block in the validate_test.go file into
three blank-line-separated groups: (1) standard library imports (context, os,
path/filepath, testing), (2) third-party and Kubernetes imports
(github.com/stretchr/testify/assert, sigs.k8s.io/... , k8s.io/... etc.), and (3)
project-local imports (github.com/devfile/... and your controller packages),

make fmt to apply formatting.

In `@webhook/workspace/handler/validate.go`:
- Around line 81-84: validateEndpoints currently returns raw errors from

update validateEndpoints to return (nil, err) for h.Client.List failures and
(conflictErr, nil) for validation failures, then in ValidateDevfile (and the
other call site around lines 109-112) check the error return first and convert
infrastructure errors into admission.Errored(http.StatusBadRequest, err) (or
propagate the error) instead of appending to devfileErrors, only append
conflictErr.Error() to devfileErrors when the typed conflict value is returned.

workspace by UID but still inspects workspaces that are being deleted; modify
the loop that iterates workspaceList.Items (and the check around otherWorkspace)
to also skip any otherWorkspace with a non-nil DeletionTimestamp (i.e., treat
terminating workspaces as excluded from discoverable endpoint conflict checks),
so that discoverableEndpoints lookup and potential return of
solvers.ServiceConflictError only considers non-terminating workspaces.

- Line 1: Update the copyright header in
webhook/workspace/handler/validate_test.go by changing the year range string "//
Copyright (c) 2019-2025 Red Hat, Inc." to the current-year range "// Copyright
(c) 2019-2026 Red Hat, Inc."; locate and replace that exact header line at the
top of the file so it matches the required format used across Go sources.
- Line 58: The test currently ignores the error from dwv2.AddToScheme(scheme);
change this to explicitly assert success by calling assert.NoError(t,
dwv2.AddToScheme(scheme)) so the scheme initialization failure surfaces in the
test; locate the call to dwv2.AddToScheme in validate_test.go (the variable
scheme) and replace the `_ =` ignoring pattern with the assert.NoError check
(using the existing testify/assert import).

In `@webhook/workspace/handler/validate.go`:
- Around line 24-29: Reorder the import block in validate.go so imports follow
Go grouping: first any standard-library packages (none shown here), then a blank
line, then third-party and Kubernetes imports together (e.g.,
"github.com/devfile/api/v2/..." packages and
"sigs.k8s.io/controller-runtime/..." client and admission), then a blank line,
and finally project-local imports (e.g.,
"github.com/devfile/devworkspace-operator/apis/controller/v1alpha1" and
"github.com/devfile/devworkspace-operator/controllers/controller/devworkspacerouting/solvers");
ensure there are blank lines separating these three groups and keep the existing
import identifiers (dwv2, devfilevalidation, v1alpha1, solvers, client,
admission) intact.

PR Readiness Assessment: PR #1521 — fix: identical endpoint name conflicts

Repository: devfile/devworkspace-operator
Linked Issue: eclipse-che/che#23231 — Dev Workspace Controller Loop with Identical Endpoint Names on DevWorkspace


# Criterion Verdict Notes
1 Problem Statement PASS PR body and linked issue clearly describe the bug: workspaces with identical discoverable endpoint names cause controller to loop and workspaces get stuck on "Preparing Service"
2 Reproduction Steps PASS Linked issue provides sample devfile and clear steps. PR body includes comprehensive test scenarios with exact commands and YAML manifests for both same-namespace conflict and cross-namespace isolation
3 Expected Behavior After Fix PASS Clear acceptance criteria: same-namespace conflicts should be rejected by webhook with specific error message; cross-namespace workspaces with same endpoint names should run successfully
4 Scope of Changes PASS 13 files changed with focused scope: controller conflict detection, webhook validation, and comprehensive test coverage. Changes are cohesive and well-explained
5 Test Evidence PASS Extensive manual testing instructions with exact commands and expected outputs. New unit tests added in common_test.go and validate_test.go. CodeRabbit confirms extensive test coverage
6 Deployment & Verification Notes PASS Detailed verification steps with specific oc/kubectl commands, expected webhook denial messages, and service verification across namespaces. E2E test checklist included

Overall: READY


Missing Information

None — this PR is exceptionally well-documented.

What's Good

  • Comprehensive test plan: Includes two distinct test scenarios (same-namespace conflict detection and cross-namespace isolation) with complete step-by-step commands
  • Clear problem statement: Both PR description and linked issue explain the controller loop bug with screenshots and environment details
  • Well-defined expected behavior: Explicit acceptance criteria for both conflict and non-conflict cases, including exact error messages
  • Excellent reproducibility: Sample devfiles, exact YAML manifests, and verification commands provided
  • Appropriate scope: Changes are focused on conflict detection logic, webhook validation, and corresponding tests
  • Strong test coverage: Both unit tests (added in the diff) and detailed manual testing instructions
  • Cross-referenced documentation: Links to external issue for full historical context

Handle hidden foreign Services with a non-caching ownership check.

A foreign Service without DevWorkspaceIDLabel is invisible to the filtered cache. The inlined-Service path can then pass checkForExistingObject, and SyncObjectWithCluster can receive NotFound, get AlreadyExists from Create, and return NeedRetryReason on every reconcile. The async-storage path can reach the same branch directly.

Use api.NonCachingClient for this Service path. Validate ownership before synchronization. Reject a foreign Service, and call syncObjectAfterRead only for a Service owned by specObj. Passing an unvalidated foreign Service to syncObjectAfterRead can update it through the generic Service diff.
