- * WaveLogApi.kt — WaveLog 日志服务器 API v2 客户端(4.5.2, 覆盖修复)。
+ * WaveLogApi.kt — WaveLog 日志服务器 API 客户端(4.5.2 覆盖修复 2)。
  *
- * 端点(文档 /temporary/wavelog_docs/docs/developer/api-v2/):
- *   GET  {base}/api/v2/token            whoami(测试连接,任意有效 token)
- *   GET  {base}/api/v2/station/{id}     站点信息(id/name/gridsquare)
- *   POST {base}/api/v2/qso              创建 QSO(qso:write)
- * 认证: Authorization: Bearer wl2_xxx(v2 token)
- *
- * URL 处理(用户实测 404 修复):
- *   1. normalizeUrl 去掉用户输入的尾部 /index.php(我们自己拼, 避免重复)
- *   2. 先试带 index.php 的路径; 404 时自动回退到不带 index.php(服务器重写配置)
- *   3. 409 conflict = 重复 QSO(已存在) → 视为成功(移出队列)
- *   4. 失败信息带实际 URL + HTTP 码, 便于排查
+ * 同时支持 v1 与 v2(用户服务器实测只有 v1, v2 返回 404):
+ *   v2: POST {base}/api/v2/qso            (Authorization: Bearer + JSON 字段)
+ *   v1: POST {base}/index.php/api/qso     (key 在 JSON body + ADIF 字符串)
+ * 策略: 优先 v2, 404 自动降级 v1。
+ * 测试连接: v2 GET api/v2/token → 404 时 v1 POST api/get_contacts_adif。
+ * 站点网格: 仅 v2 有 GET api/v2/station/{id}; v1 无此端点 → 降级用用户 QTH。
