- 确认 GO 的字段/入口：x=D(float)、y=B(float)、rotation=S、scaleX=L、scaleY=I、width=C、height=Z； GO.D(FFFFF)V 就是编辑器自己的 setTransform(x,y,rotation,scaleX,scaleY)。 依据：载荷 JSON 写入器 sb_0.java:669-675 + javap -c GO（两条独立证据）， width/height 与 mega_dg4.png 真实像素 157x154 对上。 - 确认删除入口：Gn.L()V => skeleton.removeAttachment(this,true,true)；GP.L=附件表、GP.Z=插槽表； 占位附件是载荷类 Hi（hi_2.java 的 I() 返回 "placeholder"）。 - 实机(JDK8 attach，进程 56177 全程没重启)：20 个新建插槽的图片附件 x/y/rotation 归 0、scale 归 1； 20 个 Hi 占位附件删除；骨架附件表 43 -> 23；逐个核对删除占位没连带删掉图片附件。 - 顺带把 tools/live（attach 热更工具源码）入库，jar/build 加进 .gitignore。
