可以。下面我按“核心关键词 + 核心观点”给你做一个高密度总结，尽量做到后面一眼就能把这一周的脉络捞回来。

**核心关键词**
- `PSC`
- `Private DNS`
- `Response Policy`
- `FQDN`
- `HTTPS / SNI`
- `SAN`
- `Wildcard Certificate`
- `URL Map`
- `hostRules`
- `routeRules`
- `urlRewrite`
- `hostRewrite`
- `GKE Gateway`
- `Service Attachment`
- `Kong`
- `Nginx`
- `长域名`
- `短域名`
- `共享入口`
- `证书治理`
- `命名规范`

**核心观点**
- `PSC` 解决的是私网连通，不解决证书域名匹配。
- `Private DNS / Response Policy` 解决的是“域名解析到 PSC IP”。
- `SAN` 解决的是“这个域名是否被证书合法覆盖”。
- 所以真正可用的 HTTPS 方案不是单点能力，而是：
  `PSC + Private DNS/Response Policy + SAN覆盖的证书 + 正确SNI/Host`
- 在 PSC 场景里，客户端应该尽量始终访问 `FQDN`，不要直接访问 `PSC IP`。
- `SAN` 是证书层能力，不是 DNS 替代品，也不是路由替代品。
- 百度证书案例说明了一个关键现实：
  现代 TLS 主机名校验主要看 `SAN`，不是看 `CN`。
- 大量 SAN 往往意味着“共享 TLS 入口”或“共享网关”，不一定是异常。
- `Wildcard` 不是万能的，它只适合命名规则稳定的场景。
- 你这周最关键的一个发现是：
  `*.app.aibang` 不能覆盖 `api01.team01.app.aibang` 这种两层子域。
- 这意味着短域名命名规则会直接决定证书和架构复杂度。
- 如果短域名改成 `team01-api01.app.aibang` 这一类单层子域形式，证书治理会显著变简单。
- 对你当前平台，`SAN` 最适合承担“统一证书与 TLS 入口”的职责。
- 真正能减少 `Nginx` rewrite 和兼容配置的，不是 SAN，而是 `URL Map`。
- `URL Map` 的关键能力是：
  `hostRules + routeRules + urlRewrite`
- 它适合做：
  短域名入口不变、内部改写到旧路径、浏览器地址栏不变化。
- 如果目标是保留：
  `https://www.aibang.com/API01`
  同时新增：
  `https://api01.team01.app.aibang`
  那么推荐方向不是 30x 跳转，而是内部 rewrite。
- 所以你现在最值得推进的架构分工是：
  `GLB/URL Map` 做 TLS 终止、Host 路由、Path Rewrite；
  `Nginx` 尽量退化成稳定后端。
- 对生产化来说，你已经识别出的后续重点包括：
  监控、容量、证书轮换、DNS 边界、变更流程、故障演练。
- 如果要做 V1，最稳妥的策略始终是：
  保留旧链路不动，新增新入口，不先替换。

**一句话总纲**
- `PSC` 管网络连通
- `DNS` 管名字到 IP
- `SAN` 管名字到证书
- `URL Map` 管名字/路径到后端
- `Nginx` 应该尽量少做入口适配

**你这一周最值得记住的 5 个结论**
1. `SAN` 很重要，但它不是 PSC FQDN 的完整答案。
2. `Private DNS/Response Policy` 是 PSC HTTPS 场景的基础设施级解法。
3. `api01.team01.app.aibang` 这种命名会让 wildcard 证书失去很多简化价值。
4. 想简化 Nginx，重点要用 `URL Map rewrite`，不是继续堆更多 `server_name/location`。
5. 最现实的演进路径是“长域名保留 + 短域名新增 + GLB前移能力 + 后端逐步去兼容层”。

如果你愿意，我下一步可以把这份总结再压缩成一版“20 行以内速查卡片”，或者整理成一个 `weekly-summary.md` 放进仓库。

| 指标              | W10-W11 | W12-W13               | 变化 |
| ----------------- | ------- | --------------------- | ---- |
| Total Commits     | 21      | 26                    | +24% |
| Files Modified    | 80+     | 100+                  | +25% |
| Technical Domains | 5       | 7                     | +2   |
| Primary Focus     | PSC/PSA | Cross-Project Gateway | 演进 |
| New Domains       | -       | iOS, GLB              | 扩展 |

**趋势观察:**
1. **架构演进** - 从 PSC 基础概念 → Cross-Project Gateway 实现
2. **领域扩展** - 新增 iOS 开发和 GLB 专项
3. **深度增加** - CSM 从基础配置 → Node Pool 管理
4. **工具链完善** - SSL verification scripts 增强版

## Conclusion

**Primary Achievement:** 完成了 **Cross-Project PSC Gateway** 从设计到实现的完整文档化，包括架构设计、FQDN 解析、SAN 配置、Gateway 连接等全链路细节。

**Technical Depth:** 
- GCP Networking: PSC/PSA/GLB/NEG 深度整合
- Service Mesh: CSM 控制平面 + 数据平面 + Node Pool 管理
- Nginx: Proxy Pass/Transfer-Encoding/Headers 完整配置
- SSL/TLS: Debug/Verify/OpenShell/GSKit 工具链

**Documentation Quality:** 高 - 多层文档从概念 → 实现 → 调试，但存在碎片化问题需要整合。

**Work Pattern:** 高频同步提交表明多分支/环境并行开发，建议优化同步策略减少提交噪音。

**Next Phase Focus:** 
1. 文档整合与索引建立
2. 端到端架构图绘制
3. 自动化测试覆盖
4. DropOCR App 发布准备
