## 决策 6：原版缺陷的修正确认（2026-11-01）

**结论**：采用随包固定 ConPTY 后，主屏 margin 的显示**优于原版观察到的错位**（原版与系统 ConPTY 都出现 `REGION_CIXED`，固定后端恢复 `REGION_C`/`REGION_D`/`BOTTOM_FIXED`）。该差异登记为**经用户确认的原版缺陷修正**，不作为与原版的差异缺陷。

**依据**：

- 原版观察：`docs/research/windterm-styled-margin-reference.md`（固定 211B 样式/切屏输入下，原生与 UI 文字均含 `REGION_CIXED`）；
- 后端对照：`experiments/conpty/results/2026-10-26-margin-backends/validation.json`；
- 用户确认：2026-11-01「windterm 如果有问题那就需要进一步处理即可，选 A」。

**边界**：

- 仅覆盖该固定场景与主屏 margin 的可见性；不外推为所有 margin/SSH/其他平台行为；
- 原生 `CHAR_INFO` 的可见性差异仍按 ADR-0007「已知差异」单独保留，不因本决策而视为修复；
- 若后续发现原版行为与该观察不一致，本决策需重新提交确认。

## 实施状态（2026-10-31）

本节记录五项决策的落地情况，避免把"已确认"误读成"已实现"或反之。
