The multi-region scenario replaces the hidden Region B script with visible Helm, Gateway API, cross-cluster alias, endpoint discovery, and rollout steps. ChangesBDD setup and multi-region installation
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: ⚪ Minimal · up to This change makes the Region B test setup explicit through DSL steps and removes the opaque setup script.

In `@tests/bdd/dsl/yamledit.go`:
- Line 67: Update WriteYAMLFromKeys at the setNested call to decode interpolated
cell values as YAML typed values before insertion, preserving booleans, numbers,
and sequences while leaving ordinary text as strings. Ensure generated YAML
retains correct types for values such as true, false, 2, and [], and add tests
that unmarshal the output and assert boolean, integer, and empty-sequence types.
In `@tests/bdd/godog_test.go`:
- Around line 1443-1446: Update the command content assertion using
commandRanThatContainsAll in the gateway wiring test to also require the
BackendTrafficPolicy and ReferenceGrant resource kinds, while preserving the
existing kubectl context and GRPCRoute checks.

In `@tests/bdd/dsl/yamledit.go`:
- Around line 54-71: The WriteYAMLFromKeys function should stop coordinating
filesystem operations: move the path existence check, parent-directory creation,
and file writing into the harness or steps layer. Keep parsePath, nested map
construction, and decodeTypedValue within the DSL package, exposing only the
YAML data or serialization needed by the caller.
In `@tests/bdd/godog_test.go`:
- Around line 1467-1471: Update both commandRanThatContainsAll assertions in the
wiring test to require the expected resource kind alongside each alias name and
IP: include kind: Service for the service resource and kind: Endpoints for the
endpoints resource, preserving the existing cluster-specific checks.
In `@tests/bdd/steps/steps_test.go`:
- Line 390: Move the Ledger.RestoreAll cleanup currently in the test flow around
Suite to a cleanup helper in harness/cleanup.go, or reuse the existing helper
there. Update the test to invoke that harness-level cleanup operation and assert
its returned error, ensuring tests/bdd/steps contains no direct
Ledger.RestoreAll call.

Move the I/O behaviors outside the DSL functions. Steps own the I/O responsibility and the DSL functions only render the YAML structure. Signed-off-by: tcfwbper <pesci861207@gmail.com>
The write-yaml restoration test called Ledger.RestoreAll directly from steps_test.go. Route it through Suite.Teardown so cleanup stays in the harness layer, consistent with the layering rule in AGENTS.md. Signed-off-by: tcfwbper <pesci861207@gmail.com>

TL;DR
Replace the opaque
install-llm-region-b.shshell script with explicit Gherkin DSL steps so every Region B setup action (override values, Helm install, gateway resources, route aliases, rollout waits) is visible directly in the feature file.Additional Details
The multi-region LLM registration scenario previously delegated Region B setup to a shell script. That hid the actual configuration from anyone reading the feature file, making failures harder to diagnose and the test harder to extend.
