Confidence Score: 4/5The change is a test-only addition with no production code changes; it is safe to merge and will not affect runtime behavior. The end-to-end flow is logically correct: all key timing, latency-fallback, and scorecard-pass conditions trace through cleanly against the fixture data. Two gaps hold the score below clean: the local backend/internal/voicee2e/support_agent_smoke_test.go — the only changed file; focus on the unused fixture fields and the

### Issue 1 of 2
backend/internal/voicee2e/support_agent_smoke_test.go:280-285
**Local `contains` silently disagrees with `voicetextsim.contains`**
The local helper does exact string comparison, while `voicetextsim.validateInput` trims whitespace before comparing. If the fixture YAML ever has a transport value padded with whitespace (e.g., `" text_sim"`), `parseSupportPack` would fatalf with "want text_sim transport" even though the actual `voicetextsim.Run` call would succeed — making the failure message actively misleading.
### Issue 2 of 2
backend/internal/voicee2e/support_agent_smoke_test.go:85-105
**Several fixture fields are loaded but never consumed**
`loadSupportFixture` populates `fixture.ExpectedAgentTextOutput`, `fixture.ExpectedTraceJSON`, `fixture.ExpectedScorecardJSON`, `fixture.ScriptedUserTurnsJSON`, and `fixture.ExpectedToolResultJSON`, but none of these are referenced anywhere in the test. In particular, `fakeDeploymentScript` sources the happy-path agent text from `script.Steps[0].ExpectedAgentText` (the separate `voicesim` script file), completely bypassing the canonical `ExpectedAgentTextOutput` embedded in the fixture pack. If these two sources drift apart, the smoke test will keep passing while the fixtures are inconsistent.

loadSupportFixture populates fixture.ExpectedAgentTextOutput, fixture.ExpectedTraceJSON, fixture.ExpectedScorecardJSON, fixture.ScriptedUserTurnsJSON, and fixture.ExpectedToolResultJSON, but none of these are referenced anywhere in the test. In particular, fakeDeploymentScript sources the happy-path agent text from script.Steps[0].ExpectedAgentText (the separate voicesim script file), completely bypassing the canonical ExpectedAgentTextOutput embedded in the fixture pack. If these two sources drift apart, the smoke test will keep passing while the fixtures are inconsistent.
