+# S1: emit‑only 再生成 → 正規化ハッシュ一致
+# S2: 1‑pass Fixpoint → もう一度一致
+#
+# 使い方（2通り）
+# 1) 既存の v1 JSON ファイル同士を比較（S1/S2の結果を与える）
+#    tools/selfhost/bootstrap_s1_s2.sh --in1 a.json --in2 b.json
+#
+# 2) コマンドから v1 JSON を生成して比較（emit コマンドを渡す）
+#    tools/selfhost/bootstrap_s1_s2.sh --cmd1 'bash gen_v1_once.sh' --cmd2 'bash gen_v1_twice.sh'
+#    （各コマンドは v1 JSON を stdout に出力すること）
