E2：状态回读 18.1us（N=1000x2 逐值一致）；LISTEN 可见延迟 100% <=10ms 无长尾（24 轮）-> "每 poll 全量刷新"成立、reconciler 去抖 可减为 1。 E3：GET_CMD_STATUS 对 OPEN/LISTEN/CLOSE 无判别力（残留假阳性）， 定案 cmd_done 用状态回读判据；SET 类命令态永不更新。 E4：排渣序列定案=读空 RX -> CLOSE -> 排空事件(quiescent) -> 轮询 byte0=00H；C 变体（不排渣）0/20 且级联自持，Trap 23 残渣 恰等于单 Socket RX 缓冲整容（rxdrain=2048，19/20）。 E2 补充发现（Phase 15 板测）：LISTEN 态 CLOSE_SOCKET 二段关闭 （一次只拆监听 byte0 恒 05，再发一次才落 00）——Trap 09 open 重试环的芯片级原因。 bench：ch395f_reuse_bench.c 复活 N30_CHIP_BENCH 门控实验区 （旧 N-30 矩阵 s_bench_legacy=0 停泊），ch395f_reuse_host.py 增 --mode e4。注册（uvprojx/main.c）实验完已还原不入库。

* @file ch395f_reuse_bench.c
|
||
* @brief N-30 芯片级 Socket 复用时序台架（裸机，内核前运行，OS/net/FTP 全剥离）
|
||
* @details 直接调用 ch395f_* 命令，循环执行受控时序矩阵（延迟/关闭次序/载荷/Socket 号），
|
||
* 每步打印芯片状态与中断寄存器，定位"关→开→监听→连接"复用时序中
|
||
* 芯片行为的确切规律。配套主机脚本 test/host/ch395f_reuse_host.py。
|
||
* 定案结论与实验矩阵演进 → CH395F_Trap_Records.md Trap 25。
|
||
*
|
||
* 存档状态：本文件在主分支**不注册编译**（未加入 uvprojx），仅作实验工具存档；
|
||
* 运行方法：在实验分支（如 n30-chip-bench）把本 .c 注册进 uvprojx Test 组、
|
||
* Src/main.c 的 USER CODE 2 区在 app_main_init() 之前调 ch395f_reuse_bench()
|
||
* （内核前裸机循环，永不返回，断电退出），烧录后跑主机脚本对照芯片日志。
|
||
* 旧 N-30 定案矩阵（对照 vs "丢 CONNECT 捕获自 accept"修复组）保留在 s_vars[]/
|
||
* bench_round()，由 s_bench_legacy=0 停泊不运行。
|
||
*
|
||
* 2026-10-13 N34 阶段 2 前置实验（task-9）：同一固件合并跑 E2/E3/E4——
|
||
* E2 = GET_SOCKET_STATUS 单次 SPI 成本（DWT 周期计数）+ TCP_LISTEN 可见延迟矩阵；
|
||
* E3 = GET_CMD_STATUS 判别力矩阵（OPEN/LISTEN/CLOSE/SET_SOUR_PORT/SET_PROTO_TYPE，
|
||
* 含"命令未发时"对照读，复核 Trap 记录的 SET 类无判别力 + 陈旧 BUSY 残留）；
|
||
* E4 = sock_reset 内部顺序 A/B/C 变体 ×10 轮（轮间换端口）+ 立即复连载荷完整性自证
|
||
* （配套 test/host/ch395f_reuse_host.py --mode e4）。
|
||
* 判据与结果 → docs/网络/N34-自愈审计/实验方案.md E2/E3/E4 条目与实验记录节。
|
||
*
|
||
* close_mode：0=主机先关（芯片等 DISCONNECT）；1=芯片先关；2=无数据连上即关
|
||
* verify：0=无修复；1=listen 后确认 LISTEN 重试；2=缓冲重分配；
|
||
* 3=幽灵耐心等；4=等 CONNECT 期轮询状态+自 accept（定案修复）
