两份工作互锁（互相引用），故同一笔提交。 数据可信：全文按「五级台阶」重排（§1 全局 → §2 信度现状 → §3 M4 退出判据逐条 → §4 设计约束 → §5 任务卡 → §6 顺序 → §7 决策 → §8 风险 → §9 边界 → §10 关系）。 恢复 §2.2 量纲错配（该节此前被瘦身删掉，test/host/prot_dim 的两处引用一直悬空）； 新增 §2.7 与 §4.6：ADC 只验过直流静态标定，正弦动态波形一次也没采过——用信号发生 器在既有注入点注 ±2 V 以内的正弦即可验全周傅氏、测频、快照与削顶路由，不必往端子 加压、也不需要标准源。§6 手绘框图改 Mermaid。章节编号未重排：§2 / §4 / §7 / §10 被 App 与 test 的头注释当规范引用。 故障录波：用户裁定 2026-10-29 录波先行，三条口径——1 kHz（每周波 20 点）、8 路 电气量全录、一屏只画一路共 8 路可切换。新增设计说明（与产品需求 80 点/周波口径的 偏离显式登记；存原始码值而非工程量，绕开未标定闭锁与测频幅值门；四个所有者的跨 任务边界与三条并发陷阱；段文件字节布局；单通道回放显示契约；约 5.9 KB 静态增量 触发 R6）与卡片登记簿（数据面最小闭环 → 手动与保护启动触发 → 现场单通道回放页， 二期的 4 kHz、突变量启动、COMTRADE、104 文件传输不返工的结构约束写进设计文档）。 两张旧配图与一张新配图改由 tools/arch_diagram/ 的生成器产出，脚本与产物同笔提交。 代码一行未动：本波只交付文档与设计。
