+- **公网 Gitea + 内网炼境为标准拓扑（2026-07-02 裁决）**：观测面以 G6 出站轮询为主（每 10 分钟），webhook 仅作同网/有穿透场景的补充。理由：① 炼境 27190 端口（MCP 路由无鉴权）保持零公网暴露；② 飞轮是统计系统非监控系统，10 分钟延迟在天/周分析粒度下为零影响；③ /ship 在 enterprise-system 已实证全出站 API 可支撑完整 PR 流水线；④ 主动拉取更贴合风筝线"持线人"定位。若未来需秒级实时：云服务器 nginx 仅反代 /webhook/gitea/ 路径 + 内网穿透（备案，不建议）
+- 不用 frp 直接映射 27190：MCP Server 工具路由无鉴权，全端口暴露 = append_project_note 等工具裸奔公网

 ## 复盘笔记
 
+【复盘】G6 远端轮询采集（2026-07-02）
+任务类型: 后端命令 + 前端组件
+复杂度: M
+实际轮数: 1轮（预估 1 轮）
+是否返工: 否
+有效策略: 需求源自真实拓扑约束（用户确认公网 Gitea + 内网炼境），先做安全裁决（否决 frp 全端口映射）再写代码；解析函数纯函数化可测；复用 record_commit 幂等性使轮询与本地 watcher/全量导入三路径共存不重复计数
+遗留风险: ① 轮询间隔 600s 硬编码，仓库数大时（50+）单轮串行请求可能拉长，届时可加并发或间隔配置；② limit=50 意味着 10 分钟内单仓库超 50 commit 会漏采（实际不可能，全量导入可兜底）
+auto_applied_rules: R01, R07
+rule_effectiveness: R01=有效（gitea_poll_now 命令与 commands.ts 封装同步）, R07=有效（解析纯函数 2 测试）
