 - `2925` provider 会拉长单轮轮询窗口，并关闭 Step 4 / 8 的自动重发间隔，减少因邮件延迟过早判负。
 - Hotmail 在 Step 4 / 8 首轮轮询时会优先使用最近一次验证码请求时间作为时间窗口；如果中途触发重发，轮询窗口也会同步前移，避免旧邮件反复命中。
+- 自动重新发送验证码次数现在使用 sidepanel 里的单一“验证码重发”配置；普通邮箱仍按 25 秒间隔节流，Hotmail / 2925 不走这个 25 秒间隔。Step 4 若启用先请求新验证码，会先消耗一次当前步骤的自动重发次数。
 - CPA 模式下，Step 8 在真正回填登录验证码前，会先刷新最新 OAuth 地址并快速重走一次 Step 7，降低验证码等待过久导致 OAuth 过期的概率。
 
 - Auto 模式下，如果 Step 4 当前轮失败，后台会沿用当前邮箱回到 Step 1 重新开始当前轮，而不是立刻换邮箱开新尝试。
