 # pipeline_core
 
+产线核心模块 —— 管理产线定义、步骤编排、版本控制、发布流程。
+
+## 功能
+
+- **产线管理**：产线 CRUD，定义产线名称与描述
+- **步骤编排**：产线步骤的增删改查，支持依赖关系（DAG）
+- **版本控制**：产线版本发布与回滚
+- **编辑器**：可视化产线步骤编排界面
+
+## 数据表
+
+| 表 | 说明 |
+|---|------|
+| pipelines | 产线定义 |
+| pipeline_steps | 产线步骤（含 deps 依赖） |
+| pipeline_versions | 产线版本快照 |
+| llm | 大模型配置 |
+
+## 安装
+
+```bash
+cd pkgs/pipeline_core && pip install .
+```
+
+## 集成
+
+伞仓 (pipeline-app) 通过 wwwroot symlink 加载本模块：
+```
+wwwroot/pipeline_core -> ../pkgs/pipeline_core/wwwroot

+## Data Model
+
+| Table | Key Fields | Purpose |
+|-------|-----------|---------|
+| `pipelines` | id, name, description | Pipeline definition |
+| `pipeline_steps` | id, pipeline_id, step_name, step_type, step_order, deps (JSON) | Step DAG nodes |
+| `pipeline_versions` | id, pipeline_id, version, config (JSON) | Version snapshots |
+| `llm` | id, name, provider, model, api_key | LLM model config |
+
+## DSPY Endpoints
+
+### Pipeline Management
+- `pipelines_create.dspy` / `pipelines_update.dspy` / `pipelines_delete.dspy` — standard CRUD
+- `get_pipelines.dspy` — list with optional filters
+
+### Step Orchestration
+- `pipeline_steps_create.dspy` / `pipeline_steps_update.dspy` / `pipeline_steps_delete.dspy`
+- `get_pipeline_steps.dspy` — list steps by pipeline_id
+- `get_step_types.dspy` — enumerate available step type handlers
+- `save_steps.dspy` — batch save full DAG from editor UI
+
+### Version Control
+- `pipeline_versions_create.dspy` / `pipeline_versions_update.dspy` / `pipeline_versions_delete.dspy`
+- `pipeline_publish.dspy` — snapshot + activate version
+
+## Pitfalls
+
+- **sor.R() 3-arg → sqlExe**: Do NOT use `sor.R('table', where, sort)`. Use `sor.sqlExe("SELECT ... ORDER BY ...", params)`.
+- **get_sor_context not DBPools().sqlorContext**: DSPY files must use `get_sor_context(env, 'pipeline')`.
+- **CRUD generated dirs**: `wwwroot/pipeline_steps/`, `wwwroot/pipeline_versions/`, etc. are auto-generated by `xls2ui`. Never edit directly — modify `json/*.json` and re-run `build.sh`.
+- **load_path.py**: Every new .dspy must be registered. No wildcards.
