Add an HTTPRoute for the event-ledger service to the nvcf-gateway-routes Helm chart, gated on nvcfGatewayRoutes.routes.eventLedger.enabled. - Add httproute-event-ledger.yaml with three GET-only match rules: PathPrefix /v3/ledger/namespace (namespace-scoped read endpoints), Exact /status (dependency status), and Exact /health (liveness). Write endpoints are intentionally excluded; they are reachable only via in-cluster Service DNS. - Add eventLedger route entry to values.yaml with hostname events.<domain>, backend event-ledger.nvcf:8080, enabled by default. - Wire nvcfGatewayRoutes.routes.eventLedger.enabled in global.yaml.gotmpl to addons.eventLedger.enabled so the route is skipped when the addon is disabled.

Add render coverage for the new route.
Extend deploy/helm/gateway-routes/scripts/test-render-routes.sh to verify that the route renders only when enabled. Verify its hostname, backend, paths, path types, and GET methods. Verify that disabling addons.eventLedger.enabled renders no HTTPRoute.
As per coding guidelines, “Code changes must include tests, or the Pull Request must explain why tests are not applicable; run the repository-native test runner before committing.”

Propagate eventLedger.routeAnnotations to the chart.
ingress.gatewayApi.routes.eventLedger.routeAnnotations is currently ignored in self-managed deployments. This prevents operators from applying route-specific Gateway configuration, unlike the other HTTP routes.
Proposed fix
eventLedger:
enabled: {{ dig "addons" "eventLedger" "enabled" false .Values }}
+ routeAnnotations:
+ {{ dig "ingress" "gatewayApi" "routes" "eventLedger" "routeAnnotations" dict .Values | toYaml | nindent 8 | trim }}📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

TL;DR
Add an HTTPRoute for the event-ledger service to the
nvcf-gateway-routesHelm chart. The route is enabled by default and gated bynvcfGatewayRoutes.routes.eventLedger.enabled, which the self-managed stack wires toaddons.eventLedger.enabled.Additional Details
Event-ledger is a new control-plane service that records deployment stage events from NVCA and SIS, backed by Cassandra. This PR adds its external-facing gateway route so operators can reach the read API at
events.<domain>.The route intentionally exposes only GET endpoints:
PathPrefix /v3/ledger/namespace— namespace-scoped stats and event readsExact /status— dependency status (authenticated)Exact /health— liveness check (unauthenticated)Write endpoints (
POST /v3/ledger/...) are intentionally absent from the HTTPRoute; they are reachable only via in-cluster Service DNS from NVCA and SIS.The
global.yaml.gotmplchange wiresnvcfGatewayRoutes.routes.eventLedger.enabledtoaddons.eventLedger.enabledso the route is automatically skipped when the addon is disabled, preventing a dangling backend reference.Depends on: #803 (event-ledger stack integration)
