- account_providers:新增 meProvider(GET /v1/me,登录态变化自动重取)、 plansProvider、usageProvider(family by days)。 - isFreePlanProvider 改为派生自 meProvider.plan(去掉可写演示开关)。 - quotaProvider:总额取 plans free.daily_minutes,今日剩余取 me.quota_today_min (后端已算好);adUnlocked 保留本地态(ad SDK 未接)。 - account_page:邮箱/套餐/到期接 me;删「演示:免费版视角」开关 + kDemoEmail; 协议标签 WireGuard→REALITY/Hysteria2。 - 重写 quota_controller_test 为 provider 驱动;account/quota golden 重生成。 flutter analyze 0 error;113 tests passed。统计页(weekly/月流量/延迟)随 P4 一并接(其均延迟依赖 P4 实测探针)。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
