1) CallGenMixin.vp（跨模块 extern 实参提升）：指针目标形参改为无条件走 coerce_to_type——原守卫按整数位宽比较，而指针类型的 bits 恒为 0，整段提升被跳过，致 VirtualAlloc(0,...) 以 i32 传入指针形参、mlir-opt 报 operand type mismatch（ViperAIChat 失败）。 2) CallGenMixin.vp（默认参数限定键）：改用 StructGen._resolve_module_sha1 解析模块 SHA——原只精确匹配模块名，import x as y 这类别名取不到真实 SHA，默认值表落空、跨模块调用实参数目不符（ViperRequestsTest 失败）。 3) 11 个文件的 TypePrint 类型文本缓冲 512→4096（分配与传入 size 成对修改）：48 字段类（如 MNIST 的 Net）的 MLIR 结构体类型文本超过 512 被截断并 fail-fast。
