From a35e7b2735c5f3b565aa814b20988a328284d144 Mon Sep 17 00:00:00 2001 From: wassname <1103714+wassname@users.noreply.github.com> Date: Tue, 9 Jun 2026 03:23:49 +0000 Subject: [PATCH] feat: gt_only env-mode + queue baseline/no-loophole ceiling - rewards.py: add "gt_only" EnvMode (channel=False always, honest oracle) - problems.py: add "gt_only" hint (no-op, keeps original "should pass all tests") - justfile: queue-baseline (steps=0, fast zero-shot eval, prio 80) and queue-no-loophole (gt_only vanilla GRPO, prio 11) - main.tex: Table~\ref{tab:anchors} placeholder comparing paper baselines (base 11.5% / vanilla 14.9% / no-loophole ceiling 22.3%) to ours Jobs queued: 23 (baseline, prio 80), 24 (no-loophole, prio 11).
