让标点回归测试在旧键碰撞时失败。

当前两组 ID 生成的旧键分别是 A,B,C 和 A@t1,B,C，不会碰撞。因此恢复旧实现后，断言仍会得到 4，测试无法保护 JSON 编码回归。

请让两组 ID 在旧的逗号拼接下相等，但仍产生不同的违规提议。

   const p = makePipeline([
     step("P"),
-    step("A", { needs: ["P"] }), step("B", { needs: ["P"] }), step("C", { needs: ["P"] })
+    step("A@t1", { needs: ["P"] }), step("B", { needs: ["P"] }),
+    step("A@t1,B", { needs: ["P"] }), step("C", { needs: ["P"] })
   ]);
   const runs = [
-    { at: null, by: "human", triggeredBy: "demo", steps: [{ id: "A", at: "t1" }, { id: "B", at: "t1" }, { id: "C", at: "t1" }] },
-    { at: null, by: "human", triggeredBy: "demo", steps: [{ id: "A@t1,B", at: "t1" }, { id: "C", at: "t1" }] }
+    { at: null, by: "human", triggeredBy: "demo", steps: [{ id: "A@t1,B", at: "t1" }, { id: "C", at: "t1" }] },
+    { at: null, by: "human", triggeredBy: "demo", steps: [{ id: "A@t1", at: "t1" }, { id: "B", at: "t1" }, { id: "C", at: "t1" }] }
   ];
   const v = suggestRetirements(p, { runs }).filter((s) => s.kind === "violation-precedence");
-  assert.equal(v.length, 4, "两条 run 内容不同：run1 断 A/B/C 三条边、run2 断 C 一条，共 4 条");
+  assert.equal(v.length, 5, "旧逗号键会合并两条 run 的 C→P 违规；JSON 键应保留全部 5 条");
