+    - 草稿区首次打开且字段为空时，会优先回填最近一次成功发布的模板；没有历史时，回退到当前 pack/provider 目录里的现有 provider，最后才使用静态样例
+    - `Provider ID` 现已按 `display_name / base_url / supported_models` 自动生成，并在与现有 provider / draft 冲突时自动补后缀避重
+    - 当新填的 `supported_models` 已在现有 provider 或草稿里出现时，页面会直接提示“同模型已存在”，并优先建议复用已有 `provider_id`，避免因为“官方 / 中转”重复新增同一模型定义
+    - `GET /api/packs/{pack_id}/providers` 现已补充返回 `base_url / smoke_test_model / supported_models`，用于前端做模板参考和模型冲突提示
+    - 2026-05-28 继续把这条规则下沉到服务端：`POST /api/provider-drafts`、`PUT /api/provider-drafts/{draft_id}`、`POST /api/provider-drafts/{draft_id}/publish` 现在都会做 pack 级模型冲突校验；同模型若已被其他 provider / draft 占用，会直接返回 `409 provider_model_conflict`
 - 2026-05-26 已把“最终用户 -> 公网域名 -> OpenClaw”这一跳补进正式验证口径：
   - 公网根地址当前统一为 `https://sub.tksea.top`
   - OpenClaw 本地 `MiniMax` 运行时故障已定位为 `pi-ai/openai-node` 未继承系统 `HTTP(S)_PROXY`，不是 allowlist 或模型名大小写问题
