network: 台架 IP 迁到 192.168.31.100，并把重复写死的值收进单一真源 
分两段（用户裁定 2026-11-02）：先做地址迁移，再把同类字面量收敛成
单一真源，以后再改地址只动一处。

一、IP 迁移 192.168.1.100 → 192.168.31.100（gw 同步 → .31.1）
- 工厂默认：Drivers/BSP/NETCFG/net_cfg.c 的 NET_CFG_DEF_IP/_GW
- 注释/文档示例、主机与板级测试、台架 py 脚本、两份 sim_config.ini
- 字节序教学点同步换算 hex：0x6401A8C0 → 0x641FA8C0（内存
  C0 A8 1F 64），旧版示例引文与历史 Trap 记录按冻结纪律不动
- UI 黄金基准：网口设置 4 态 + shot_info 共 5 张 .bin 由
  check_content_pages.py --update 重刷（渲染值 IP 变了，属预期变更）
- 保留判定：客户点表引用（IEC104/继电保护规划）、芯片手册摘录、
  日期冻结的变更记录行、已退役台架档案 MDK-ARM/retracted_bench_*

二、单一真源收口（A+B+C+D，用户批准全做）
- 新建 test/host/bench_defaults.py：台架 py 默认值唯一定义点
  （DEVICE_IP/DEVICE_GW/PC_IP/NET_BCAST），22 个脚本改为引用；
  MDK-ARM 两探针与 scripts/board_ui_nav.py 经 sys.path shim 引入
- test/board/net_test_task.h 新增 TEST_PC_PEER_IP，板测三处
  PHASE*_REMOTE_IP 改引该宏（保留 -D 覆盖）；Phase1 断言改
  memcmp 数组比较，数组各只出现一次
- simulator/tests/check_content_pages.py 从 net_cfg.c 正则解析
  NET_CFG_DEF_* 推导期望值（解析失败即报错、不静默兜底），
  脚本内台架 IP 字面量清零
- 装饰性注释去具体值（net_cfg.h/net_socket.h/net_socket.c/
  net_socket_sim.c）；字节序教学 hex 对刻意保留为唯一写值点
- 刻意不动：主机单测夹具 IP（逐文件钉住的任意值是正确测试
  实践）、文档正文 IP（那是文档内容本身）

顺带：scripts/gen_task_table.py 规范串清掉「，B5」——编号清退提交
72b4b094 改了受管区没重跑生成器，task-table 门禁因此一直红

验证：产品 @build 0/0；CH395F 套件开关构建 0/0 后还原产品态；
6 套主机单测 rc=0；content_pages（含宏推导路径）/菜单 8 态/
推流位比对全 PASS；bom-drift 99 无漂移；doc-links/coding-standard/
cppcheck 绿；py_compile 23 文件 + --help 冒烟（含 shim 绝对路径）

"""B6 bench leg: IEC 60870-5-104 master client (GI + COV round-trip).
Historical bench leg; current acceptance index: docs/任务规划/登记簿.md §7.
docs/子系统设计/IEC104上行设计说明.md §3/§4. Constants mirror
App/protocol/iec104/iec104_asdu.h / iec104_link.h.
Flow:
1. TCP connect device :2404 (factory default; --port overrides),
STARTDT act/con (enter RUN).
2. General interrogation C_IC_NA_1 (QOI=20): expect actcon, background
scan (YX double-point group SQ=1 -> YX single-point group SQ=1 ->
YC group SQ=1 -> frequency single point), actterm.
3. Deterministic COV trigger: bench analog inputs are floating (phasor
rms is 0..0.3 raw-code noise only; the standard source belongs to
B10), so we use the two-step C_SE_NC_1 write to temporarily lower
the OC1 current setting (comm addr 0x8858, default 10.0 A) to
0.05 A -> protectTask (20 ms cadence) asserts OC1 -> YX16/YX15
spontaneous (COT=3) uplink. This is exactly the "104 YX linkage"
leg left open by B5. Then restore 10.0 A -> YX16 returns.
4. YK11 (0x600A) two-step select/execute -> positive actcon (reset
request consumed asynchronously by protectTask, B5 contract).
5. C_RD read back 0x8858 ~= 10.0 (restore confirmation).
Exit codes: 0 = all checks PASS; 1 = any check FAIL; 2 = connect or
protocol error. Output is pure ASCII (redirect stdout to archive the
round-trip log as bench evidence).
RX decode fix (2026-10-25, task-21/m104fix): cause-byte semantics above;
offline sample-frame selftest: python test/host/test_iec104_master_rx.py
Usage: python iec104_master.py [--ip <设备IP>] [--port 2404]
[--addr 0x8858] [--low 0.05]
[--restore 10.0]
B7 bench leg modes (setpoint persistence + global soft plate; historical
bench leg, firmware side App/cfg/prot_set_store.c):
--b7-pre : before reset: mark setpoint 7.5 (C_SE+C_RD), YK12 OFF (two-step)
-> low setpoint 0.05 must NOT trip YX16 (plate OUT disables
protection); YK12 ON -> YX16 trips (linkage); restore 10.0;
leave plate OUT (persistence proof), wait for dirty->save.
--b7-post: after reset: C_RD 10.0 (setpoint persisted); low setpoint 0.05
still must NOT trip (plate OUT persisted); YK12 ON -> YX16
trips (linkage after reboot); restore 10.0, leave plate IN.
--b7-mark / --b7-check [--mark 7.5]: write a distinctive NON-default
setpoint (save), reset, read it back (literal "setpoint
hold" proof, distinguishable from factory default), restore.
