docs: 谐波B行按板端前端真实衰减关闭——结论现状化与登记
- 执行手册：用户裁定删除 §8.6–§8.10 尾部（顺序/分诊/还原/归档节）；
谐波 B 行结论只留现状（删万用表分诊、三点拟合、嫌疑解除等过程叙述）
- 定案：250 Hz 读数 −4.4 % = IA 前端差分滤波（C35 100 nF + R19/R21
各 1 k，一阶低通 fc ≈ 796 Hz）真实衰减，板端读数忠实、量算皆对；
工频 50 Hz 仅 −0.2 % 不受影响；选择性成立；谐波产品化需板改
- 通道映射 §8.2 新增前端 RC 段：逐阶外推（21 次 −39.6 %，改 10 nF
后 −0.9 %）、改板优先于软件修正的理由、证伪条件（250 Hz 附加滞后 ≈17°）
- 数据可信.md：§2.7 谐波行同步；任务卡打勾保留并标注四项未闭合
（叠加轮/削顶低频档/测频改码档/模型仪器证伪）；README 顺位表 ✅
- 登记簿 §3 新增「IA 前端差分滤波限制谐波带宽」条目（语义标识）
- 证据：ia_rc_model.py 输出归档 boot_log_data 并入 manifest（LF 重算
md5）；速查图生成器脚注同步并重跑（脚本与产物同笔）
- check_doc_links --all 通过（3206 处、无法判定 0）
