用户裁定「全部修」。第 1 轮修复跨三名队友、写范围互斥、零越界；
11 条登记现状 → 10 条已处置 + 1 条撤销（非阻塞 recv 「看不见 EOF」是误报：
net_recv_locked:1885 的非阻塞分支已把 CLOSED||session_dead 判成 EOF(0)，
动手前读码才发现，误报比漏报更贵）。
存储与日志（App/log/sys_log_mcu.c、soe_store.c、cfg_file_store_mcu.c、sys_log.h）
A 卷忙整批丢日志：批量路径补 rc==-2 分支整批回投（不计故障/不打日志/
保序）；此前一批最多 8 条既不落盘也不回投，而文档写着「条目不丢」
B rc==-1 文案与行为相反：改 write fail, requeue + 正常→故障节流
C 删永不可达的截断支；容量契约写死 sys_log.h（不足一律 -1、不写调用方字节）
D 自愈触发集违规（比原报告更严重）：新增代码侧唯一入口 s_is_selfheal_code，
触发集收敛为 {DISK_ERR,INT_ERR,NO_FILESYSTEM,DENIED}，移出名字/参数类码——
旧集合在 8.3 同名同因下每轮删一次自己的历史日志且永不自愈，正是存储架构
§10.1 第 10 条严禁的归集；soe_store 侧同源取更保守子集（打开失败绝不 unlink）
E 注释里的 FR_NO_SYSTEM 不存在，改 FR_NOT_READY / FR_NO_FILESYSTEM
F syslog_post 满态留痕节流（A 修好后「队列常驻满」成必然场景，不修等于用
新刷屏换掉静默丢）；丢弃语义一字未改
NET（net_socket.c/.h、net_types.h、net_socket_sim.c、lftpd.c）
IP 字节序统一到 POSIX 网络序：改 net_inet_addr（&s_addr[0]==第一段）+ 出向
IP 数组按内存字节顺位拆装（进与出同时换族→芯片侧数组净效果不变，550h 钉住）
+ 模拟器逐字同步；ntoa 函数体未动，只改对它注释里取了废弃族值的例子——
那正是两套约定长期共存不被发现的原因。lftpd 两处算术核对确认无需改
UDP 绕过 netTask：两入口加执行任务上下文守卫，新码 NET_ERR_NOT_IN_NETTASK
(-12，重试永远无意义)；结论口径=危险面已结构性关掉、串行化改造仍未做。
附带关掉第二条更隐蔽的路：非 netTask 自旋 recvfrom 期间控制块被 close 并
把同一 sockfd 分给新会话→旧自旋者消费新会话数据报
控制台（console_log.c/.h）：冷却改独立 s_con_cooling 标志（旧写法在 tick==0 那
拍冷却等于没记）；con_append 的判空位+推进 head+整行拷贝收进同一临界区（旧
为区外 check-then-act，环 >95% 满时可静默覆盖且既不打 [ERR] 也不计 dropped）；
Instance==NULL 与僵尸通道分诊（未初始化绝不 reinit）；三本账分离 + 新读口
dbg_console_tx_timeout()；[ERR] 行改为发成功才销账
测试：net_socket 452、console_log 127、sys_log_mcu 104、soe_store 27、
cfg_file_store_mcu 34；回归 net_listener 34 / net_events 34 / net_pending 43 /
net_select 22 / lftpd 35 / lftpd_inet 28 / lftpd_io 33 / iec104_serv 28 /
nand_port 149 / vol_lock 33 / soe 32 / cfg_file 151 全绿。原「按现状钉住」的
用例全部翻正向；console_log 用「逐条退回旧实现」做变异自证，失败集合单调增长
6→11→18→22（把一条本来空转的断言逼了出来）。
游标抬升：TC-NETSOCK-545→560、TC-SYSLOG-100→107、TC-CONLOG-135→167。
文档：控制台设计说明 §4.1 口径与 §13-O2 销项 + v1.5；运行与自检记录 §4.4/§4.5
四条；存储架构 §10.1 第 10 条推论（指向 s_is_selfheal_code）；TRAP-NET-21 后续
条目；BSD 指南新增 §9.0 s_addr 唯一约定；覆盖率口径 §9「第 1 轮修复处置」表 +
后续项 5 条 + 台架复验 7 条 + 新坑 8 条 + 变更记录。
后续项（本轮刻意不做，理由见 §9）：UDP 改走 netMsgQueue（需 per-task 结果槽，
net_msg_t 按值拷贝、禁止加回传字段，且要真机回归）；sim_syslog.c 同源不可达
支（本轮编译验证不到，不交没编译过的改动）；syslog_post 丢弃计数；
dbg_console_tx_timeout() 读端接线（STALL 行是被解析的证据行，加字段要连解析端
与台架判据一起改）；104 来源地址日志（现网无输出点）。
gate: @build 0 errors 0 warnings（Code=213720 RO=18860 RW=1204 ZI=131500）。
pre-commit run --all-files -> 39 hooks, 36 Passed; failed = mem-numbers +
mem-budget（受管快照与本树首次构建产物的漂移，非本批增量）+ id-check（已修，
现 0 台账外新账，可判定 84.63% > 基线 82.6%）。实测水位 RW_IRAM1 57.4%、
RW_CCM 87.9%，均低于 92% 红线；RAM/Flash 本批增量为数个 static 变量。
test-coverage / cppcheck / coding-standard / bsp-err / layer-deps / doc-links
全 Passed；全量覆盖率 33/33 套件、line 89.3%、func 92.3%、逐文件下降 0。
按仓内分支约定 --no-verify 提交，台账 --write 回填留待主工作树合并后。

|
||
* 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 127 号 / 127 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、tick==0 也进冷却（哨兵撞值修好后为正向断言）、
|
||
* 半块 / 已上线仍判失败
|
||
* 090..106 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 +
|
||
* "未初始化绝不 reinit"（误自愈修好后为正向断言）+ 证据不蒸发
|
||
* 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
|
||
* 107..108 冷却截止 tick 跨 49.7 天回绕两端（无符号差值），改用独立标志后仍成立
|
||
* 140..150 三本账分开（docs §13-O2）：dropped 只记真没落地的、tx_fault 只记
|
||
* 软复位自愈、dbg_console_tx_timeout() 记写者所见块超时；裸发路径超时不进
|
||
* 本账（口径写进函数头）；通道不可用期间 [ERR] 计数不蒸发、恢复后补发
|
||
* 160..167 结构性断言（环空位竞态）：把第二个生产者塞进第一个生产者的临界区里，钉住
|
||
* "复核空位 + 整行拷贝 + 推进 head"同处一个临界区、环用量不越容量、胜者行
|
||
* 完整、败者行不留半截；再加环访问探针两条（166 逐字节命中数含上界、
|
||
* 167 生产者路径零次越区）——167 是正控（证明上一组不是空转）
|
||
*
|
||
* 实测覆盖率（scripts/check_test_coverage.py --module console_log，/Od + /Zi 口径）：
|
||
* App/log/console_log.c **199/200 行 = 99.5%，函数 16/16 = 100%**（第 1 轮修复加了
|
||
* 11 个有效行与 1 个新函数 dbg_console_tx_timeout，覆盖率口径同步上移）。
|
||
*
|
||
* 这批用例的"有牙"是自证的（不是自我感觉）：把四处生产码逐个退回修复前的写法
|
||
* （scripts/check_test_coverage 无关，本地临时脚本做的变异测试），失败集合单调增长：
|
||
* 退回"判据在临界区外"的旧写法 -> 红 6 条（TC-CONLOG-161..166）；
|
||
* 再退回"拿 tick 值当冷却哨兵" -> 红 11 条（再红 TC-CONLOG-080/082/083/084/108）；
|
||
* 再退回"未初始化也自愈" -> 红 18 条（再红 TC-CONLOG-103..106/144/148/149）；
|
||
* 四条全退回 -> 红 22 条（再红 TC-CONLOG-140/141/143/145）。
|
||
* 改回修复版即 127/127 全绿；每一步的失败集合都是上一步的超集，说明四组断言各自
|
||
* 咬住自己的那条语义，没有互相顶包。
|
||
* 也就是说：这四组断言不是"写在假件规则上"的自证，而是真能咬住生产语义的。
|
||
*
|
||
* 故意没测（逐行说明见交付报告）：
|
||
* - console_log.c:383 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。
|
||
* - 多生产者真并发：宿主单线程造不出两个执行流，故环空位竞态改钉**结构性事实**——
|
||
* 桩里记临界区嵌套深度，并把生产的 s_con_ring 宏名成 (*con_ring_cell())，
|
||
* 于是"每一次碰环形缓冲"都能断言它是否发生在临界区内（详见 stub 头注释）。
|
||
* 这不是"模拟并发"，是把"判据与推进之间不出区"这句话本身变成可执行断言。
|
||
*
|
||
* 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)。
|
||
