根因(真机排查):QuadRemesher 引擎在激进减面下非确定性地从封闭流形 输入打出孔洞/非流形边(实测同一输入约 85% 次数破碎),即"破碎面"。 修复:QR 导回后比对输入拓扑,若比输入新增开边(孔洞)/非流形边即判破损、 弃用 QR 回退 collapse(topology_acceptable 纯策略+单测;_edge_defects 计数)。 顺带修复水密门在导入后拒绝时未恢复 obj 选中态,导致 collapse 回退时 export use_selection 选不到对象、只导出 4KB 空 FBX 的 bug。 含用户改动:--reducer 默认改为 quad(配合水密门,破碎自动回退,安全), 及其 CLI 默认值测试。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
