// tools/llm-judge.integration.test.mjs
// Live ProxyAPI integration smoke for the LLM-judge core (Checkpoint 1 deliverable).
//
// OPT-IN ONLY: runs only when ROUTER_LLM_LIVE_TEST=1 AND ROUTER_LLM_KEY is set.
// It is intentionally NOT gated on key-presence alone, because:
//   (1) the real call path imports `undici` via tools/router-classifier.mjs, which is
//       installed in app/node_modules — not resolvable from every worktree root, so an
//       unguarded live test would hard-fail in environments where undici is absent;
//   (2) the live smoke is a master-session / Checkpoint-1 responsibility, not part of
//       the per-stream unit regression (all unit logic is covered by mock-LLM tests).
//
// To run the live smoke (in an env where `undici` resolves, e.g. with deps installed):
//   ROUTER_LLM_LIVE_TEST=1 npx vitest run tools/llm-judge.integration.test.mjs
