test(host): P2 覆盖率批次，5 套主机单测与共享假 FatFs
P2 五个文件全部进分母（三名队友并行，写范围互斥、零越界）：
net_socket 420 条 / 881-883=99.8%、52-52 函数（S1~S6 分片）
sys_log_mcu 75 条 / 310-313=99.0%、12-12
console_log 104 条 / 188-189=99.5%、15-15
cfg_file_store_mcu 34 条 / 97-97=100%、10-10
soe_store 26 条 / 78-79=98.7%、4-4
合计 659 条断言，P2 本体 1554-1561=99.6%、93-93 函数。
账：套件 28→33 全绿；files_tested 32→37；未触及 112→107（.c 34→29，
恒等式 29 = 0(P1剩) + 0(P2) + 29(P3) 咬合，§9 终点判据达成）；分母
4684→6245 插桩行；line 85.8%→89.3%；func 90.1%→92.2%（这批 5 个文件
全都以 ≥98.7% 进分母，故未摊薄）。--update-baseline 前后逐文件比对：
下降 0 个文件。
基建：新建 test/host/common/fatfs_fake.{h,c}（以真实 ff.h 为声明源、只
定义三文件实际调用的 9 个 f_*，缺哪个链接期响；卷忙/短写/FR_DENIED
可注入；短名违规分档）；扩展 ch395f_fake 为纯新增（g_fx/g_fxchip 另开
一份世界 + ext_reset 挂进既有复位，既有三套面一字不动），并按真头修正
两个错值常量（SOCKET_OPEN 0x01→0x05、TCP_ESTABLISHED 0x05→0x04），
另在 net_socket runner 加真头/假件同名常量文本核对闸（负例验证过）。
存量回归：net_listener 34、net_events 34、net_pending 43、net_select 22、
nand_port 149、lftpd_io 33、vol_lock 33、soe 32、cfg_file 151 全绿。
编号：补 TC-HOST-{NETSOCK,SYSLOG,CFGFST,SOESTORE,CONLOG} 五族（22→27，
先补族再引号）；net_socket 模块码由自取的两字母 NS 正名为 NETSOCK；
id-check 增量拦截无台账外新账，可判定比例 83.27%（基线 82.6%）。
文档：覆盖率口径 §9 新增「P2 落地」（含两套分母口径差、10 条现状表、
12 条可复用手法与并发红线），§8 第 1 条改「清单已吃穿」，补变更记录。
本提交未改任何生产代码（App/Drivers/Src/Lib/MDK-ARM 零触碰）。
10 条现状已逐条登记在 §9（含 sys_log_mcu.c:509~537 卷忙整批丢日志、
net_socket.c 同文件两套 IP 字节序、UDP 两 API 绕过 netTask），已获指示
全部修复，另开一轮（含测试字面量统一纯 ASCII）。
gate: pre-commit run --all-files → 39 hooks, 38 Passed; only mem-numbers
Failed（本工作树从未 @build，无 .map 事实源，属分支期已知陷阱）；
mem-budget Passed；test-coverage 与 id-check Passed。RAM/Flash 增量 = 0
（纯测试批次）。按仓内分支约定走 --no-verify，台账回填留待主树合并后。

|
||||
* 模块名称：控制台单写者日志（console_log）主机侧单元测试
|
||||
* 模块功能：在 PC 上离线验证 App/log/console_log.c 的单写者契约（G1~G5 / K1~K5，见
|
||||
* docs/子系统设计/控制台单写者日志设计说明.md）：环形缓冲入环与分块发送、
|
||||
* 行级原子、192B 截断、写者未注册/ISR 上下文的无锁直发、缓冲满有界等待与
|
||||
* 丢弃可观测、TX 僵尸通道软复位自愈 + 300ms 冷却、DWT 与指令计数两种硬上界、
|
||||
* huart1.Instance 未初始化的 NULL 短路、fputc 重定向、drain 250ms 预算。
|
||||
*
|
||||
* 为什么要主机侧单测（而不是只用台架）：
|
||||
* 本模块的风险全在"异常时刻"——UART 僵尸通道卡死、TIM7 停摆导致 uwTick 不往前走、
|
||||
* 开机 1.7s 喂狗容限被背靠背块超时吃掉（台架实测的停喂误复位）、写者注册前多任务裸发
|
||||
* 逐字节交错（2026-10-10/10-12 台架实证）。台架上这些要么一年一遇、要么现场已被
|
||||
* 复位冲掉；而它们的判据全是"数得清的数"：192B 上限、256B 分块、4095B 可用环、
|
||||
* 200 tick 等待、20000 次计数上界、100/250/300ms 三条时间线。把它们做成断言，是这台
|
||||
* 设备上唯一能把这几条线钉死的办法（板端套件只能"在真机上跑一遍"）。
|
||||
*
|
||||
* 桩的边界（细节见 stub/stm32f4_fake.h 头注释）：
|
||||
* console_log.h / sys_events.h（含真实 SYS_EVT_CONSOLE_TX 位）用**真实头**；
|
||||
* usart.h 用桩，但只暴露本模块访问的 huart1 + MX_USART1_UART_Init，寄存器位号 /
|
||||
* 枚举值照抄真实头；USART SR 的 TXE/TC、DWT CYCCNT、HAL_GetTick、临界区、
|
||||
* __get_IPSR、vTaskDelay、osEventFlagsSet 做成可控 + 可观测的量。
|
||||
* ⚠ 本文件**刻意不定义**任何 syslog_* / DBG_* 符号：console_log.c 哪天把"TX 故障
|
||||
* 留痕"改回直接调日志子系统，链接就失败——那正是必须挡住的（write_line →
|
||||
* con_append → drain → syslog_post → write_line 成环，静态栈深在每个任务上虚高）。
|
||||
*
|
||||
* 覆盖点（编号族 TC-CONLOG-*，属主登记处 = 本文件；实占 104 号 / 104 条断言）：
|
||||
* 000..006 宿主 printf 与本模块 fputc 的隔离 + 参数校验与 192B 截断
|
||||
* 010..018 写者未注册 = 无锁直发（不入环、不置事件位、零临界区、不等待、256B 有界）
|
||||
* 020..038 注册后走环形：入环不发送、按 256B 分块、多生产者不交错、跨环尾两段拷贝、
|
||||
* 入环长度钳 RING/2
|
||||
* 040..044 写者自记录先排空（不自等）/ drain 重入保护 / 未注册时 drain 让位
|
||||
* 050..062 缓冲满：DWT 硬上界丢弃、不覆盖旧行、等待中出现空间、无 DWT 时 200 tick
|
||||
* 上界、[ERR] dropped 直发不经环、读后即清
|
||||
* 070..088 TX 僵尸通道：软复位自愈序列、故障即止、WARN 只一次、tx_fault_log_take
|
||||
* 读后清、300ms 冷却两端、无符号回绕、tick==0 哨兵现状、半块/已上线仍判失败
|
||||
* 090..104 DWT 惰性使能三处寄存器写、使能失败退回 20000 次指令计数、超时判据不读
|
||||
* HAL_GetTick（round 8b 动机）、huart1.Instance == NULL 短路两路
|
||||
* 110..117 fputc 重定向（未注册直发 / 注册逐字节入环 / ISR 上下文裸发 / 环满时 ISR
|
||||
* 仍不等待）
|
||||
* 120..122 drain 单次 250ms 预算与下轮续排（让位喂狗但不丢字节）
|
||||
* 130..135 计数支路也能把整块发完（不只会超时）+ 其 TC 计数上界 + DWT 支路 TC 抖动
|
||||
* 后正常收尾 + con_append 直调时的自有参数校验
|
||||
*
|
||||
* 实测覆盖率（scripts/check_test_coverage.py --module console_log，/Od + /Zi 口径）：
|
||||
* App/log/console_log.c **188/189 行 = 99.5%，函数 15/15 = 100%**。
|
||||
*
|
||||
* 故意没测（逐行说明见交付报告）：
|
||||
* - console_log.c:352 唯一未覆盖行：snprintf 溢出后的钳位 `n = sizeof(note)-1`。
|
||||
* note[64]，前缀 24B + "%lu"（unsigned long 最多 10 位）+ 后缀 8B = 最长 42B
|
||||
* < 63B，任何输入都到不了这一行 —— 纯防御，不是漏测。
|
||||
* - 真实周期时间量级：主机没有真 DWT CYCCNT 也没有 TIM7 的 uwTick，只能钉"判据在
|
||||
* 第几次读成立 / 自旋几次放弃"，不能声称"实测 100ms 就返回"。
|
||||
* - ISR 与写者同时裸发的真总线交错（docs §13-O1）：宿主单线程，造不出两个执行流。
|
||||
* - osEventFlagsWait 唤醒写者与 50ms 兜底：写者任务体在 App/task/default_task.c。
|
||||
* - MicroLIB 真实 retarget 链接语义：宿主 CRT 有自己的 fputc（实测与本模块符号
|
||||
* 冲突 -> LNK2005），故本 TU 把被测 fputc 改名纳入，只验函数体不验链接钩子。
|
||||
*
|
||||
* 通过：全部 TC PASS（main 返回 0）。
|
||||
* 入口：int main(void)，返回 0=PASS / 1=FAIL；跑飞保险 exit(2)。
|
||||
*
|
||||
* 创建日期：2026-10-24
