ADDED Requirements

Requirement: Boundary-specific smoothing strength

O Image Depth Cutout SHALL 使用单个 Boundary Smooth 输入控制边界平滑次数。Split 边 SHALL 使用完整 Smooth Weight，原始 Outline SHALL 使用 0.1 倍 Smooth Weight；两类影响相交时 Split 强度 MUST 优先。

Scenario: Separate Split and Outline response

• WHEN 同一网格同时存在 Split 边与原始 Outline 且启用 Boundary Smooth
• THEN Split 边按完整 Smooth Weight 平滑
• AND 仅受 Outline 影响的点按其 0.1 倍平滑

Scenario: Split and Outline intersection

• WHEN Split 与 Outline 的两圈影响范围相交
• THEN 相交区域使用两者中较强的 Split influence

Requirement: Boundary Smooth default and bypass

O Image Depth Cutout 的 Boundary Smooth SHALL 默认为 4，保持范围 0–16；值为 0 时 MUST 完全旁路边界平滑。

Scenario: New node group defaults

• WHEN 构建新的 O Image Depth Cutout 节点组
• THEN Boundary Smooth 默认值为 4

Scenario: Disabled boundary smoothing

• WHEN Boundary Smooth 为 0
• THEN Split 边和 Outline 均不发生边界平滑位移
