Frame 0010 · 四个失败位置 × 四条候选线 → 新 mask

每个 block 的 RGB 和 residual 均作为独立 512×512 PNG 输入。 C1 白=+64，C2 洋红=+128，C3 黄=+192，C4 薄荷绿=+256 px。 选择最小的完整覆盖候选后，以 Gaussian 空间权重平滑组合局部半径，避免方形 crop 接缝。

Residual 仍是有偏辅助：轮廓外 residual 可以否决候选， 但低 residual 不能证明覆盖。最终组合使用 RGB-first 的选择。

Block 01 · C2 · +128 px

Confidence 1.00. User-locked conservative override: apply C2 at the recentered rightmost cushion site to guarantee coverage of its lower-right corner and floor-contact halo.

Separate critic input A · RGB · four candidate lines
Separate critic input B · biased residual · four candidate lines

Block 02 · C1 · +64 px

Confidence 0.93. C1 encloses the visible edges of all cushion components in this block, including the frame-cut lower cushion and thin corner halos.

Separate critic input A · RGB · four candidate lines
Separate critic input B · biased residual · four candidate lines

Block 03 · C1 · +64 px

Confidence 0.96. The upright cushion and its lower-left protruding corner sit comfortably inside the white contour with no coherent residual reaching it.

Separate critic input A · RGB · four candidate lines
Separate critic input B · biased residual · four candidate lines

Block 04 · C1 · +64 px

Confidence 0.94. C1 separately surrounds the upright, flat, and partially visible foreground cushions and contains their complete residual fringes.

Separate critic input A · RGB · four candidate lines
Separate critic input B · biased residual · four candidate lines

Judge ONE frame-0010 boundary location at a time.

You receive two separate 512x512 PNG images for the same location:
A. true observed RGB;
B. biased Round-1 residual.
They are separate visual inputs, never a merged composite.

Four thin candidate hard-mask boundaries appear in both images:
C1 white/black = +64 px
C2 magenta/black = +128 px
C3 yellow/black = +192 px
C4 mint/black = +256 px

Choose the SMALLEST candidate that encloses every visible part of the local
transient object indicated by the current mask. Include thin tips, small
protrusions, translucent or defocused boundaries, motion/defocus halos, and
color/blur trails. The existing mask may under-cover the object. Do not expand
merely to include unrelated static background. If even C4 fails, return
INSUFFICIENT.

Residual construction: mean absolute RGB difference between dirty observed and
the Round-1 3DGS render, Gaussian sigma 1.8, clipped at 0.30, Turbo colormap.
The render was trained with an earlier undercovered mask and can reproduce
leaked transient pixels. Therefore coherent residual outside a line proves
that line insufficient, but low residual never proves coverage.

Return: selected candidate, radius, confidence, and one concise RGB-first
reason.
