+# B300 ds41 部署 compose 档案
+
+b300-01 上 DeepSeek-V4.1-Flash 各部署方案的 docker compose 存档。
+**本目录是 source of truth**；b300 上的运行目录 `/data/ymk/ds41/` 是工作副本。
+
+方案说明、参数矩阵、特殊 env、已知坑见飞书部署手册（组内共享）：
+《B300 sglang 部署手册》 https://u04wb5irxz.feishu.cn/docx/FOi8dbnybodHr0xIfkPcQ6gtnRx
+
+## 同步流程
+
+```bash
+# 本机（D:\B300\sglang）
+git add deploy/ && git commit -m "deploy: ..."
+git push origin dsv41-pd-visioncp   # Gitea（paths-ignore，不触发镜像构建）
+git push b300 dsv41-pd-visioncp     # b300 裸仓库
+
+# b300-01
+git -C /data/ymk/sglang pull        # deploy/ 出现在 /data/ymk/sglang/deploy/b300-ds41/
+```
+
+## CI 说明
+
+`.gitea/workflows/build-image.yaml` 的 push 触发器带 `paths-ignore: ['deploy/**', '.gitea/**']`，
+改本目录不会触发镜像构建。注意：workflow 自身的改动也不再自动触发，需要重建镜像时
+伴随代码改动 push 或手动触发。
+
+## 目录规则
+
+- 命名：`dockerserve-<拓扑>-<特性>-<卡位>.yml`（如 `-b4` = 后 4 卡）
+- 退役文件不要留在主目录：移入 `archive-YYYYMMDD/`（b300 侧同样执行）
+- 禁止提交 `.bak` 备份文件
+- `mooncake-store.json` 是 hicache L3 mooncake store 配置，被
+  `dockerserve-pd2-p-r1/r2.yml` 通过 `SGLANG_HICACHE_MOONCAKE_CONFIG_PATH` 引用
