feat(workflow): item 25A 最小 workflow 执行 runtime (CC 2.1.229) - #105
Merged
Conversation
WorkflowTool.execute() 原为纯验证桩,从不执行脚本。落地最小可执行
runtime: agent()/parallel()/pipeline()/phase()/log() 原语 + runId
传播 transcript+telemetry。
- runtime.ts (NEW): executeWorkflow() + evaluateScript() (Bun.Transpiler
剥 TS → 花括号平衡抽 meta → new Function async IIFE 封装) + 并发信号量
池 min(16,cpu-2) + isWorkflowRuntimeEnabled()。agent() 用 runAgent
drain → getAssistantMessageText, transcriptSubdir=workflows/<runId>。
- WorkflowTool.ts: 双门禁分支 feature("WORKFLOW_SCRIPTS") 编译期 AND
FUSION_WORKFLOW_RUNTIME_ENABLED=1 运行期。去下划线接 context/
canUseTool/onProgress。activeRuns 转 completed/error。emitPerfettoInstant
runId。禁用时 byte-identical 桩。
- build.ts: WORKFLOW_SCRIPTS 加入 fullExperimentalFeatures (dev:full 启用)。
- workflowRuntime.test.ts (NEW): 23 单测 (env gate, meta 抽取嵌套/字符串,
eval 顶层 return/await/TS 剥类型, parallel 并发/throw→null, pipeline,
log/phase/budget/workflow-NotImplemented/args/残留 export 抛错)。
DEFERRED v1: schema (返回纯文本), 嵌套 workflow() (抛 NotImplemented),
budget (stub)。默认 off, 全 env-gated。
验证: typecheck 0, 23/23 workflowRuntime, 210/210 全套, build+build:dev:full
pass, dev:full bundle 含 runtime, standard bundle DCE runtime。

背景
Closes #104
WorkflowTool.execute()是纯验证桩——生成runId、检查export const meta存在、写activeRunsMap、立即返回status:"started"，从不执行脚本。无parallel()/pipeline()/agent()/phase()runtime。transcriptSubdir通道全连通但 0 caller。onProgress接入但被忽略。activeRuns只写不转 completed/error。方案 (L-size, 双门禁 default-off)
落地最小可执行 runtime：脚本能跑
agent()/parallel()/pipeline()/phase()/log()，产出结果，runId 传播 transcript + telemetry。变更
