1.17.5 引入的 tests/fixtures/ex_history_transaction.json 含中文注释，Windows CI 默认用 cp1252 解码 UTF-8 文件触发 UnicodeDecodeError: 'charmap' codec can't decode byte 0x8f，导致 3 个 Windows 矩阵的 test_parse_ex_history_transaction_hk 失败（Linux 矩阵因默认 utf-8 不受影响）。 修复：所有 fixture 读取显式指定 encoding='utf-8'： - test_hk_transaction.py 的 load_hex/load_json（直接触发点） - test_commands_offline.py 的 load_hex（纯 ASCII hex，当前未触发但一并统一） - test_decode_errors.py 的 _load_hex（同上） 867 单测全绿，ruff format/check / mypy strict 通过。

"""港股逐笔成交协议路由的回归测试（issue #14）。
|
||
|
||
issue #14：``MacExClient.goods_transaction`` 对港股返回空。根因是它对所有扩展市场
|
||
复用了 A 股 MAC 协议的 ``SymbolTransactionCmd``（0x122F），而 0x122F 的数据源未接入
|
||
港股。修复后港股股票类市场走 ex 扩展行情协议（当日 0x23FC / 历史 0x2406）。
|
||
|
||
本测试纯离线：
|
||
|
||
1. 用录制的真实港股 0x2406 响应 fixture 验证 ``GetExHistoryTransactionDataCmd``
|
||
解析正确（价格字段为整数）。
|
||
2. 验证 ``ExTransactionRecord → MacTransaction`` 字段映射 + 价格 ÷1000 换算。
|
||
3. 验证 ``is_hk_stock_market`` 市场判定边界。
|
||
4. mock ``_execute``，验证 ``MacExClient.goods_transaction`` 对港股（market=31）
|
||
走 ex 协议路径、对其他扩展市场（market=47 期货）仍走 0x122F 路径，避免回归。
