验证目标
将 engine 从 workflow-cas 切换到 json-cas,thread 执行使用新 schema。
前置
工作内容
1. Engine 核心替换
修改
workflow-execute/src/engine/engine.ts:loadWorkflow),不再从 bundle importevaluateModerator(rules, context)替代tableToModeratorthread-step节点(json-cas format)thread-start节点(含 workflow hash + agents binding)thread-end节点2. Store 替换
CasStore类型从@uncaged/workflow-cas改为@uncaged/json-cas的StorecreateCasStore(dir)改为createFsStore(dir)(from@uncaged/json-cas-fs)store.put(typeHash, payload)替代旧的putStartNode/putStateNode/putContentNodeWithRefs3. Context 构建
修改
workflow-runtime/src/build-context.ts:previouscas_ref)重建 steps 数组4. Worker 适配
修改
workflow-execute/src/engine/worker.ts:5. 删除旧依赖
@uncaged/workflow-cas测试步骤
Step 1: 端到端 solve-issue
用 memory store 注册 solve-issue workflow → 创建 thread → 跑完整流程 → thread-end 存在
Step 2: thread-start 结构正确
thread-start 节点包含 workflow cas_ref 和 agents binding(role → agent hash)
Step 3: thread-step 链完整
每个 step 有 content ref、start ref、previous ref(链表结构)
Step 4: thread-end 记录正确
returnCode + summary + start ref + lastStep ref
Step 5: walk 遍历完整
walk(threadStartHash)遍历 thread-start → 所有 steps → 所有 content 节点Step 6: content 读取正确
从 step 的 content ref 读取 agent 输出文本,内容正确
Step 7: fs store 持久化
用 fs store 跑一次,重新打开 store 后 thread 数据完整可读
验证完成标准
✅ 所有 checkbox 打勾
✅
bun test全过(至少 engine 相关测试)✅ workflow-execute 和 workflow-runtime 不再 import @uncaged/workflow-cas
