+- Foundation 在零产品改动下证明 `p9.1-contract-r1` 的 26 脚本清单错误：首个旧测试仍依赖当前 R10 已无的 `game.run`。
+- R10 完成记录与保留 summary SHA-256 `3de791bb6da14be19d97c194368cd14bc8bfb906013470e81b6e12da83736bf7` 明确列出 22 个权威脚本。
+- `p9.1-contract-r2` 只恢复这 22 个脚本；三个旧 Opening/Market `game.run` 测试和未列入 R10 summary 的 R3 dynamic 脚本保持原样并排除，不通过修改旧断言制造绿灯。
+- 原 terminal 归类为 `INVALID_CONTRACT_BASELINE`，不是产品 FAIL；同一角色/会话在新 context/identity ACK 后从 Step 0 重新开始。
