They also cover creation, deployment, invocation, authentication, and undeployment of an OpenAI-compatible LLM function in the multi-cluster topology. ChangesMulti-cluster function lifecycle
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The change adds split-cluster LLM BDD coverage and per-scenario workload cleanup. It is mergeable with owner awareness that a failed scenario may retain local GPU resources until the documented cleanup procedure is run.

In `@tests/bdd/features/multi-cluster-helmfile.feature`:
- Around line 347-350: The unauthenticated gateway curl command in the
multi-cluster Helmfile scenario lacks bounded connection and transfer timeouts.
Add curl --connect-timeout and --max-time options, and update the matching
fake-runner command key in the Godog test setup so the command remains
recognized.
- Around line 263-264: Move deployment cleanup for the HTTP, gRPC, and LLM
scenarios from trailing feature steps into an After hook that tracks successful
deployments and runs function delete --deployment-only even when later steps
fail. Update the cleanup sites in
tests/bdd/features/multi-cluster-helmfile.feature at lines 263-264, 300-301, and
354-354; implement the hook wiring in tests/bdd/godog_test.go at lines
1021-1029; and add a wiring test that fails after deployment and verifies the
delete command executes.

adjacent Go string literals, matching the neighboring command keys while
preserving the exact concatenated lookup value and command behavior.

Why
The multi-cluster Helmfile BDD flow installs the LLM gateway and request
router, but it only invoked HTTP and gRPC echo workloads. That left the
split-cluster LLM routing contract untested and kept every simulated GPU
deployment active between scenarios.
What changed
compute cluster.
rejection.
and a valid fixed
traceparent.documented local capacity is reused.

Testing
go test -run '^TestMultiClusterHelmfileFeatureFileWiresToSteps$' -count=1passed.go test -short -count=1 ./...passed fornvcf-bdd,dsl,harness, andsteps.go vet ./...andgit diff --checkpassed.The local
golangci-lintrun is blocked by an incompatible host toolchain: Go1.27 export data cannot be decoded by the installed linter built with Go 1.26.
Notes
The sample returns a fixed response. This validates routing, authentication,
cleanup, and request/response wiring; it does not measure token-generation
capacity or latency.
The compute fixture deliberately retains
stargateQUICInsecure: true. Securedsplit-cluster trust and invocation remain separate follow-up work blocked on
#1207 and #1075.
The live runner uses
StopOnFailure: true, so a failed scenario stops thesuite and retains state for diagnostics. A retry can use the documented
BDD_CLEANUP_MODE=stack-multipre-suite cleanup. A cross-cuttingAfterhookthat deletes state on failure is intentionally outside this focused routing
coverage.
