* security-bench.test.ts).
*
* Opt-in: only runs when `GSTACK_BENCH_ENSEMBLE=1` is set. Otherwise the

* On success this writes:
* - browse/test/fixtures/security-bench-haiku-responses.json (fixture
* consumed by the CI-gate test security-bench-ensemble.test.ts)
* - ~/.gstack-dev/evals/security-bench-ensemble-{timestamp}.json (per-run
* audit record with TP/FN/FP/TN + Wilson 95% CIs + knob state)
*
* Stop-loss iterations: when detection or FP fails the gate, set
* `GSTACK_BENCH_STOP_LOSS_ITER=N` where N in {1,2,3}. The bench writes to
* stop-loss-iter-N-{timestamp}.json and does NOT overwrite the canonical
* fixture — only the accepted final iteration gets committed.

* Regression test for the TDZ (Temporal Dead Zone) bug at the claude-CLI-missing

* Original bug:
* const claude = resolveClaudeCommand();
* if (!claude) return finish({...}); // ← TDZ: finish not yet declared
* const p = spawn(...);
* let done = false;
* const finish = (...) => {...}; // ← declared HERE, too late

* Fix: hoist `let done` + `const finish` above the resolveClaudeCommand call.
*
* This test exercises the outer guard (checkHaikuAvailable returning false when
* claude CLI is not on PATH), which is the realistic runtime path. The TDZ
* itself was inside the spawn Promise — only reachable in a TOCTOU window if
* claude went missing between checkHaikuAvailable and the spawn call. The fix
* makes that window safe regardless. This test guards against regression by
