Byte-identical copy of reopd_ref/third_party/slime (BaohaoLiao/slime, commit 26525f97179afc47c9ef6fff045dbc28d79f1875). Pinning it means a run here does not depend on whatever `pip install slime` resolves to today: a silently drifted trainer does not raise, it just stops being the baseline everyone else reports.
Includes reopd_scripts/models/*.sh (upstream MODEL_ARGS, also byte-identical) plus qwen3-1.7B.sh, which upstream does not ship and which a one-GPU student needs, and opd_math.sh.upstream to diff the launcher against.
