-The CJS workflow's **Copilot Decisions API Integration** job runs
-`node --test actions/setup/js/scripts/test_decisions_client.cjs` with
-`GITHUB_TOKEN` from a job granting `copilot-requests: write`. It makes one live
-choice request using synthetic evidence and requires a named `basket_fruit`
-answer of type `choice` with the exact value `apples` rather than `bananas`.
-This single-request API, authentication, and protocol smoke check is not a
-statistical model-quality evaluation; it uses no confidence threshold or retries.
-Missing credentials, API errors, and incorrect or malformed answers fail the test.
-The job excludes fork pull requests and Dependabot-triggered runs, whose tokens
-are read-only, and does not use PATs or repository secrets.
+Live Decisions API coverage is provided by Copilot evals rather than a separate
+integration smoke test.
