传输指纹单变量实验: errorCode=12 是否由 HTTP/TLS 指纹决定?

依据: AGENTS.md §2.1 (用服务端响应画生死线) / §5.6 (先怀疑自己的工具) / ANALYSIS.md §7.6。

已确证的事实 (2026-10-11):
  * 同一 aid (1ms 195672344) + 同一套腾讯云登录 cookie + 同一 prehandle 参数下,
    **真实浏览器** (har/签到成功-1.har, 点选.har) 对 cap_union_new_verify 只得到
    50 / 9 / 0 —— **从不 12**;
  * 本客户端 (httpx, HTTP/1.1 + OpenSSL) 在不同 cookie / IP / 时序 / 后端下**恒为 12**;
  * 答案正确 (OCR 后验 1.0)、XTEA 密钥为实时构建真密钥 → 12 与载荷内容无关。

→ 剩下唯一被测到的差异: **"谁在发这个 HTTP"** (JA3/JA4 + HTTP/2 + 头序 + 头大小写)。

本脚本**只改传输层**, 其余 (cookie / 参数 / 题型 / 求解器) 完全相同:
    A) transport=httpx   (基线)
    B) transport=curl    (curl_cffi impersonate=chrome)

判读:
    A=12 且 B=0    -> 12 = 传输指纹问题; 纯算流程只需换传输层即可通过
    A=12 且 B=12   -> 传输指纹也不够, 需回到"真实浏览器页面上下文"(H1/H2) 或 collect 内容

用法:
    .venv/bin/python scripts/experiment_transport_ab.py --both \
        --uin 100012108023 --skey <skey> --csrf <qcmainCSRFToken> --intl 1
