+# 1049 的 SGR1 输出签名：调查合同
+
+对应 [#146](https://github.com/JavaZeroo/termforge/issues/146)，接续 #123/#126 的未知非颜色属性。[离线 false 提案](../../research/ui/results/2026-10-29-sgr1-proposal/README.md)保留执行前身份；独立预审后的[唯一实际运行](../../research/ui/results/2026-10-29-sgr1-reference/README.md)取得五阶段完整栅格，但每帧 SGR0/SGR1 控制均不可分，进入/重复进入/返回的字重状态保持 unknown。旧 raw-capture-v1 的七个生产源、计划与证据保持字节不变。
+
+目标是比较固定 WindTerm 2.7.0 在 1049 进入、重复进入与返回后，新写的 H/space 是否匹配同一张图中的 SGR0 或 SGR1 控制输出。匹配表示该固定样本的完整像素输出签名相同，不能直接解释为内部 `Style.bold`、QPainter pen 或实际字体字重相同。原版优先；重要独立差异仍需用户确认。
+
+## 五阶段与可区分前态
+
+| 阶段 | 精确输入的作用 | 采集后的源末态 |
+|---|---|---|
+| 0 | 主屏清空，SGR0/SGR1 各写两个 H 控制 | SGR1 |
+| 1 | `1049h` 后先写无 SGR 的 `E0 H H`，再写两组控制 | SGR1 |
+| 2 | 备用屏明确写 SGR0 样本和两组控制 | SGR1，为重复进入提供不同于 SGR0 的前态 |
+| 3 | 重复 `1049h` 后先写 `R0 H H`，再写两组控制；最后追加不写字的 SGR0 | SGR0，与主屏原有源末态 SGR1 区分 |
+| 4 | `1049l` 后先写 `M1 H H`，再写两组控制 | 不用于下一转换 |
+
+这里的末态来自精确发送源的声明，并非已读出的原版内部属性。返回标记前保留一个显式空格，避免与主屏末尾文字拼接而失去完整 token 绑定。每阶段源后追加一次 `CSI 6n`，只在独立 UI 确认后前进。固定输入、长度与 SHA 见[不可执行提案](../../research/ui/results/2026-10-29-sgr1-proposal/plan.json)。
+
+## 采集与分类
+
+[工具](../../research/ui/sgr1_reference.py)复用已审 raw Qt 模板，只以受保护锚点替换五阶段 marker 表、case/status 名称和输出文件名。原生 sret、QPixmap/QImage 生命周期、选择端点、marker/ROI、DPR、caret 和每阶段单次 grab 的实现不变；生成模板 SHA 与实际注入文件 SHA 分别记录。REA 固定 6.7.0，准备计划记录 shim、package.json 与入口脚本身份；这不代表完整工具依赖树已重现。
+
+每个未知样本有两个 H，SGR0 与 SGR1 控制也各有两个 H。采集保留完整有序 H/space QRgb 数组于私有目录，分类完全离线，不在采集中按颜色选择是否继续。结构、身份、空图、ROI/DPR、选择端点或 caret 失败停止；不移动 ROI、不补抓、不重试。
+
+[离线审计](../../research/ui/sgr1_analysis.py)要求同帧同一文本行、唯一位置与严格递增的 glyph 矩形、相同 ROI 形状/样本数、各组内部的完整有序签名一致。SGR0/1 控制不可分、控制重复不一致或目标未唯一匹配时保持 unknown。颜色差异、主墨色并列不阻断已经成立的完整输出签名匹配，但只记录颜色关系；`font_weight_mechanism=null` 和 `internal_bold_verified=false` 保持不变。
+
+[导出器](../../research/ui/export_sgr1_reference.py)核对执行计划、源/模块/注入脚本、全部 NAWS 事件、实际 DSR、原始消息与文件一致性、逐阶段确认和 Job/profile 回收。只输出合成源、白名单标量、派生签名和原件哈希；原始像素、资源、路径、PID、profile 留私有。早期停止不补造未冻结的网格或后续画面。
+
+## 执行与停止边界
+
+- 执行前固定生产提交、唯一新目录与单次 marker，最多一次原版启动、每阶段一次 grab；当前 false 提案不能创建 attempt 或启动目标。
+- 仅官方固定 4047 文件清单、EXE/Qt 完整 SHA、自有副本、合成 loopback Telnet、非输入 station/desktop 和 OwnedJob；不修改个人桌面、剪贴板、DPI 或会话。
+- 沿既有 REA capture 45 秒、CLI wait 60 秒与清理边界；启动在前、清理在后，没有整程 45/60 秒保证，不构成绩效测量。
+- 实际运行使用独立预审后另建的单次 true 计划。该计划已经消费，原件与 false 提案保留；离线成功不批准重跑或模拟原版执行。
+
+完整 style、内部笔刷、全网格、47/1047/1048、margin/origin/wrap、本地 Shell、物理呈现、性能及 R2 均未由本项验收。

+# SGR1 固定输出签名：离线预审材料
+
+[#146](https://github.com/JavaZeroo/termforge/issues/146) 当前仅有[工具/停止合同](../../../../docs/research/windterm-sgr1-plan.md)、[false 提案](plan.json)和[离线验证身份](validation.json)。**实际 WindTerm 启动 0 次，guest 请求 0 次**；没有原版像素、SGR1 行为或内部字重结论。
+
+工具源为 `8d44041cefbf566b5fb1eb7433bdfa0231235ef1`。其后两个提交只修改测试输入/等待：`5d18c34d94093e03871ff240c3d811e8d98757b9` 隔离旧 fixture 的共享标签列表，`14b28609b59c789d5b78e2f0463c53321e296ada` 等待新 peer 测试的记录发布。8 个生产源及 5 个离线审计源的字节与工具提交逐一一致；旧 raw-capture-v1 七个生产源、旧计划和旧证据未改。
+
+提案准备于 `14b2860`：主屏进入前源末态 SGR1，重复进入前备用屏源末态 SGR1，退出前追加不写字的 SGR0。每个未知样本与 SGR0/SGR1 控制均有两个独立 H/space；最多五阶段、每阶段一抓、一次原版启动。末态来自精确源声明，并非内部属性读数。控制可分且完整有序签名唯一匹配时只记录 `SGR0-control-output` / `SGR1-control-output`；颜色同异、并列主墨色不被解释为实际字重，机制始终 unknown。
+
+最终 Windows x64、Python 3.12.10、Node 22.21.1 的新离线套件普通与 `-O` 各 **15/15、零跳过**，包含合成完整导出逐字节相同、早期/部分停止、位置/矩形别名、零/越界 ROI、隐私拒绝、不可分/不一致控制、同直方图不同像素顺序，以及逐字节 loopback peer。新 CMake 入口只运行该套件，CTest **1/1**；未构建或运行原生产品。
+
+两项测试失败与修正分列保留：
+
+- 旧 raw/selection/peer 模块放到同一 unittest 进程时，26 项中 6 个 selection 子例失败。直接反例证明 phase0 的 `lines` 与全局 `LABELS[0]` 是同一列表，原隐私拒绝负例原地改变了后续 fixture。只复制测试列表，完全相同组合随后 **26/26**；生产源和拒绝断言不变。原有按 CTest 隔离的三个模块分别为 11/11、13/13、2/2，不用这些成功覆盖组合红。
+- 新 CTest 首次 **0/1**：测试客户端收到源字节时，peer 线程尚未发布对应记录，立即索引产生 `IndexError`。测试现在在原 2 秒条件预算内先核对记录存在，再核对原 DSR；最终 **1/1**。原失败日志和首次 false 计划保留，未加等待预算或重跑原版。
+
+日志、首次与最终 false 计划的路径只留 `local/`；公开记录其 SHA。最终私有 false 计划 SHA 为 `6d04124b88fcc9aa1325a99850ed4708ab8a7fc689cecdabee7aea5052104397`，没有创建 attempt marker 或目标输出目录。准备时只实际核对四个完整模块 SHA；完整 4047 文件清单由既有启动器在未来获准运行时再次核对，不能把准备成功当作已启动。
+
+独立预审后仍须从当时的 HEAD **另建 true 计划**，不能修改这些 false 提案或运行旧 immutable 计划。此次没有产品完整矩阵、实际呈现、性能或 R2 验收结果。

+# 原版 1049 / SGR1 固定样本：采集完整，控制不可分
+
+[#146](https://github.com/JavaZeroo/termforge/issues/146) 的唯一实际运行取得五阶段、五次独立 QWidget grab。**每帧的 SGR0 与 SGR1 双 H/space 控制完整像素签名均不可分，进入、重复进入和返回的比较结果都保持 unknown。** 这不能证明原版忽略 SGR1、不支持粗体，或 1049 保留/重置/恢复了内部字重。
+
+## 身份与实际执行
+
+- 实际执行 HEAD：`a115bc82119dcf1456e8bf9a7c0e15bee3d77174`；工具实现：`8d44041cefbf566b5fb1eb7433bdfa0231235ef1`。8 个生产源、5 个离线审计源与两提交逐一字节相同。[执行前材料](../2026-10-29-sgr1-proposal/README.md)保留其当时的零次运行状态和测试失败/修正身份。
+- 固定官方 WindTerm 2.7.0 x64 EXE SHA256：`7b10531dccc7cd614ae559f36f1ef518e0c96335637431b4646354823b2804d0`；4047 文件 canonical manifest：`e459adf2f12adb6a1b7f55e66a9da1c22794185e66e848057d21e0c60d669203`。离线重新枚举并核对源包和自有副本的全部 4047 文件、四模块完整 SHA 与实际模块路径守卫。
+- 已消费的私有 true 计划 SHA：`d0286fade7bf18f3dbea5e44ed91b8c5e1a5f595b0900978abcc758e9b06af45`；[公开计划](plan.json)删除私有路径，分别记录准备时零次与完成后一次。原 false、true、attempt、源和原件均保留，不再执行。
+- REA Evidence：`ev_c6e7637ba0e47033ec012529a35c909bb21a805f98b6743e809cdb28958721d4`。root 监督 CLI 退出 0；provider 无脚本错误、截断或 cleanup error。原始 evidence 216159B，路径、PID、profile、资源及像素数组不公开。
+- 自有非输入 station/desktop、合成 loopback Telnet 和 OwnedJob。记录的最终 Job 为 `active=0,total=3,terminated=0`，profile 检查仅一个合成会话，stderr 为空。启动器主动结束原版，不把 Job0 或 terminated0 当作自然 GUI 退出。
+
+## 五阶段观察
+
+NAWS 完整事件为 `91×24 → 91×25`，第二事件后冻结，之后无新尺寸事件。五帧均为 888×451、DPR1；28 对 H/space ROI 共 56 数组、8064 个 QRgb，单个 ROI 为 8×18。完整有序 H/space 签名在本次 28 对中只有一个值；不是仅比较直方图或主墨色。
+
+| 阶段 | 精确源条件 | 实际 DSR | 实际缓冲区 | 同帧控制 / 未知样本结论 |
+|---|---|---|---|---|
+| 0 | 主屏 SGR0/1 控制，结束为 SGR1 | (2,16) | 主屏 | 0/1 控制不可分 |
+| 1 | `1049h` 后先写 E0，再写控制 | (1,21) | 备用屏 | 控制不可分，E0 无唯一分类 |
+| 2 | 备用屏样本与控制，结束为 SGR1 | (4,23) | 备用屏 | 控制不可分 |
+| 3 | 重复 `1049h` 后先写 R0，再写控制并追加不写字的 SGR0 | (1,21) | 备用屏 | 控制不可分，R0 无唯一分类 |
+| 4 | `1049l` 后先写 M1，再写控制 | (2,37) | 主屏 | 控制不可分，M1 无唯一分类 |
+
+SGR1/SGR0 的转换前态来自已发送源声明，并非读取了内部 style。所有 marker 与实际文本、位置、矩形、DSR 和活动缓冲区分别绑定；同帧两组控制各自重复一致。正常与 SGR1 控制本身相同，所以不能利用目标匹配推导 reset/inheritance/restore。
+
+本批只核对固定发行物、合成会话、精确请求和栅格输出；没有读取实际终端 glyph 字体、fallback、字重或相关 profile 偏好的有效值。不能把同像素解释成某字体请求无效、粗体偏好关闭或原版属性未实现。没有换字符、颜色、字体或 ROI，也没有补抓或重跑。
+
+## 离线审核与发布
+
+[validation.json](validation.json)原样复制普通导出，与 `python -O` 导出逐字节相同，SHA256 为 `da5c2b2615339d057a71a94b3bd50580477f9d5e2e70a670ee1a8dde177b42d3`。[独立 stdlib 审核](audit.json)未导入探针、分析器或导出器作为 oracle；另外重算精确输入、DSR/NAWS、完整模板与实际 CRLF 注入文件、8+5 源、4047 文件、模块、五次 grab、28 对位置/ROI、完整像素签名、消息/原件一致性及回收记录。31 份私有记录保留大小和 SHA，源文件另归档于 local。
+
+结果整理前合并了 main `4d7bd8a7c822135b1fdee5935262af3205ee565f`，合并提交 `848d479af194ad8cf1f6238dc4e33774ade7da43`；这属于发布上下文，不是再次执行的源码身份。合并后没有重跑原版、REA、Node、peer 或 guest，也没有重跑 15 项或完整产品矩阵。
+
+本项只完成这次有界调查与不可判定结果的可重算发布。完整非颜色属性、内部 pen、全网格、其他模式、本地 Shell 运输、实际呈现和性能继续未知；#123/#126/#27 与 R2 不因此通过。REA capture45 秒、CLI wait60 秒不含前置启动和后续清理，不构成整程期限或性能结果。
