展开作者解与路线
c4 → c5 → c3 → c2 → c0 → c1
推理依据
- ○/△每步交替，按节点数量推断端点类别
- 永久墙 c1—c3 断开表面邻接，需绕行
关键分叉：第 5 步应走 c0，诱惑路线走 c1。排除依据：蓝橙颜色必须交替。
逐项机制必要性反例
解除 alternation 后：c4 → c5 → c3 → c2 → c1 → c0
解除 wall:0 后：c4 → c5 → c3 → c1 → c0 → c2
六向共边相邻，每格一步。蓝格 → 橙格，每步换颜色；黑黄永久墙另行封住共边。同色或有墙都不能通过。○是蓝格，△是橙格。
原始盘面和作者解分开展示。标题是设计任务，真人推理路径与难度仍需试玩验证。数字、窗口、方向、类别和开关显示在格内；步差与先后关系见逐关推理依据。
