Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The new smoke-test flow can query the wrong cluster context or stop during transient status propagation, causing false failures or unreliable validation of autoscaler behavior.

Full details: Linked Issues checkExplanation The changes satisfy both linked issues. They add autoscaler scale-up coverage, reuse the existing lifecycle, verify the response and cleanup, enable and validate Vanity Gateway routing, perform authenticated exact-host invocation, and add non-live wiring tests. Full details: Out of Scope Changes checkExplanation The changes remain within scope. Supporting fixture, CLI, validation-message, documentation, and render-regression updates directly enable or validate the requested autoscaler and Vanity Gateway BDD coverage.

inline and split --stargate-address argument forms, evaluating the following
argument as the address when the flag has no equals value. Add a table-driven
regression test covering HTTPS and non-HTTPS values in both forms, including the
existing fallback behavior.
In `@tools/ncp-local-cluster/scripts/validate-gateway-route.sh`:
- Line 26: Update the retry loop in the gateway route validation script to
enforce a wall-clock deadline using SECONDS rather than incrementing elapsed
only by the retry interval. Compute remaining time before each attempt, cap
curl’s --max-time and the final sleep to that remainder, and update the
associated test to model advancing elapsed time instead of using a no-op sleep.

#1362 tracks publishing and consuming the scheme-aware Pylon and NVCA releases after #1372 lands. This PR intentionally remains unchanged until those dependencies merge. I will then rebase it and remove the stack, component, version-pin, and generated-doc changes so its final diff contains only the autoscaler and Vanity Gateway BDD coverage. |

🎉 This PR is included in version nvcf-self-managed-stack-v0.9.0 🎉 The release is available on GitHub release Your semantic-release bot 📦🚀 |
3 participants
Why
The self-managed stack now includes a function autoscaler and Vanity Gateway, but the expensive BDD suites did not verify either core user path. These smoke scenarios catch a regression in scale-from-zero or exact-host gateway routing without adding detailed behavior coverage.
What changed
Customer Release Notes
Not customer visible.
Plan Summary
The local BDD fixture enables one Vanity Gateway replica. No default stack resources, public APIs, or component versions change.
Usage
The scenarios remain part of their existing full feature suites because they depend on the preceding stack-install and compute-registration scenarios.
Testing
go test -short ./...intests/bddtests/bdd/scripts/lint.shbash deploy/stacks/self-managed/tests/observability-autoscaler.shmainthrough test(stack): remove pinned router version assertion #1390 plus fix(llm-routing): align worker Pylon with router transport #1394 and this PR:go test -timeout 45m -run "^TestSingleClusterHelmfile$" -count=1 -v: 6 scenarios, 72 steps passed.go test -timeout 45m -run "^TestObservabilityAll$" -count=1 -v: 2 scenarios, 53 steps passed, including scale-from-zero to one running instance.Notes
