读码确认的口径缺陷：两片转换器的丢帧计数单位不一致——TPAFE 侧 adc_health_tpafe_gaps() 按 (d-1) 加权记「帧点数」，STM32 侧 adc_input_stm32_gaps() 每次事件只 +1 记「次数」。两者都被当作心跳字段 并排打印（adc1_gap / tgap），一次跨多帧时数值就分叉：同样丢 3 帧， 一边记 2、一边记 1。跨字段对比或做除法会得出错误结论。 选 A（改代码，真对称）而不是只改字段名： - 单拍超一帧（d=2）时两者数值相同，历史上绝大多数样本本来就等价， 换单位对既有判读习惯冲击很小； - 只在一次跨 ≥2 帧时分叉，而那正是心跳日志突发期最常见的形态， 留在文档里当"注意点"迟早还会读错一次。 改动： - adc_input.c：s_stm32_gaps += (d - 1u)（d = seq - s_dma_seq_seen， 顺带把已算过的差值提成局部变量 d，不再重复算一遍） - adc_input.h / adc_input.c 函数头：单位写明「Σ 每次前进的超出部分」， 并点名 2026-10-21 之前固件该字段是次数口径，跨版本日志不可直接对比 - 用例：原两档只跨 1 帧（前进 2 记 1），钉不出单位；补第二档——连投 3 帧不消费（一次跨 2 帧）必须记 2 点、累计 1+2=3。补充断言沿用所属 用例覆盖点，不另立新编号，也不在文档外复制用例号（编号门禁按文件内 实例数比对台账豁免，多写一处即被判新债） - 文档同步：ADC采样节拍设计说明 §8/§9 字段口径与稳态基线、采集与算法 层设计说明 §3/§4、采样有效性校验设计说明 §6.2/§10/§11（并把"两车道 单位不同"从观测盲区降级为"历史日志口径差异"）、ADC输入层单元测试 说明用例表该行；两张配图生成器文案同步 实测： - @build 0 错 0 警；Program Size 与上一提交**逐字节相同**（Code=213520 RW=1184 ZI=131504）——编译器早已为半区推导算过同一差值并复用， 故本次净增 0 B，不产生新的台账漂移 - 主机单测：ADC 输入层 103/103、ADC 有效性 45/45 - stack_report：adcTask 1320 B / protectTask 872 B 均不变 - 字节卫生：BOM 无 / CR 0 / U+FFFD 0 / 文件尾换行齐 - id-check：Passed（曾因新增用例号实例触发"台账之外 +2"，已按不复制 用例号的方式消除，未动 id_known_backlog.json 台账） gate: only mem-budget/mem-numbers pending lead ledger backfill pre-commit run --all-files 失败仅这两条，漂移量来自上一条提交 6f90600 （+96 B Code / +24 B ZI）；本条自身 0 B。按并行分支约定本分支不跑 --write，台账由 Lead 合并后统一回填。
