 stdin-piping runner (`runVenvScriptStdin`).
 - **Real, runnable with ZERO extra deps:** finsearchcomp (GitHub dataset + fixtures + LLM judge — the gate bench), hotpotqa + simpleqa + frames (HF/web QA + F1/LLM judge; `*_FIXTURES=1` offline), **aec-bench** (real GitHub task tree + fixtures; judge = the task's own `tests/verify.py` over python3 stdlib — **deterministic, graded per-field partial credit, no Docker, no LLM** → the candidate non-oracle correctable-middle-band bench for the open gate).

 - **goldArtifact:** aec-bench returns the task's real `golden_pass.md` (verify-judge works fully offline). commit0 / programbench / appworld return `undefined` — the oracle is a git ref / stripped source / engine-bundled solution, not a portable string; judge correctness is proven by a real solve through the harness, not a synthetic gold (documented + fail-loud, not a fake).
 - **Absent (not built):** swe-gym, swe-bench-multimodal, and the rest of the survey set.
 Every unbuilt/scaffold adapter fails LOUD (throws with the integration step) rather than faking a score — no silent zeros in any corpus. Offline fixture tests: `benchmarks/{aec-bench,commit0,programbench,appworld}.test.mts` (`tsx --test`).
