Persistent DAG Actors, real-time A2UI task canvas, Manager Supervisor, multi-round interaction, cold recovery, structured activity events.

Technical Positioning
Scalable, resilient, interactive agent orchestration; auditable and observable AI workflows; vendor-agnostic persistence; robust state management.
SaaS Insight & Market Implications
This Epic outlines `homerail`'s strategic architectural foundation for advanced agent orchestration. The core model shifts from transient DAGs to "Persistent DAG Actors" with "real-time A2UI task canvases," enabling continuous, supervised interaction. Key principles like "logical Actor long-lived, physical Worker by lease" and "Manager operates stable `actor_id`" demonstrate a commitment to scalable, resource-efficient, and resilient design. The emphasis on "vendor-agnostic checkpointing," "idempotent UI updates," and "deterministic rejection of late generations" establishes a robust, auditable framework critical for enterprise AI. This architecture positions `homerail` to deliver highly interactive, observable, and fault-tolerant agent workflows, addressing fundamental requirements for complex B2B AI applications where state persistence, auditability, and dynamic user engagement are paramount.

Epic:持久 DAG Actors、实时 A2UI 任务画布与 Manager Supervisor

## Epic 进度(2026-07-21)

- ✅ A–I(#37–#45)已全部实现并关闭,对应 PR #47–#55。
- ✅ Activity、稳定 Actor/Inbox、多轮 waiting、Worker lease/cold recovery、Projector、实时画布、Manager Supervisor、局部分支干预和三 Worker E2E 均已进入 main。
- ✅ J(#58)的三个实现切片 #59–#61 已进入 main,后续 #74 又补强了稳定 Surface 与透明 Worker 重建证据。
- ⏳ Epic 保持开放:子 Issue 进度 **9/10**;Epic 完成门槛 **10/12**。剩余门槛集中在 #58 的真实 active steering/连续追问验收,而不是基础 Runtime 缺失。

下一步只收口 #58,不再为 A–I 重开重复实现。

## 目标

让 Manager Agent 能从一个用户请求启动并监督多个并发逻辑 Actor,让每个 Actor 持续更新自己绑定的 A2UI Block;一轮 Fan-in 完成后,DAG 可以进入持久等待,物理 Worker 可按租约释放,并在后续用户命令到来时从持久状态恢复。

基线:[PR #33](github.com/xiaotianfotos/hom... 已合并,所有实现 PR 必须从包含原生 A2UI 的干净 main 开始。

## 核心模型

- **Fan-in 结束一轮,不默认结束 DAG。**
- **逻辑 Actor 长存,物理 Worker 按租约分配和释放。**
- **Manager 操作稳定 actor_id,不操作容器或临时 WebSocket。**
- **Worker 只提交结构化 Activity Event,不拥有任意 Canvas mutation 权限。**
- **Live Surface Projector 是 DAG Event → A2UI 的唯一可信写入边界。**
- **正确性依赖供应商无关的 checkpoint;模型原生 session resume 只能作为优化。**
- **所有命令先持久化、所有 UI 更新可幂等重放、所有迟到 generation 确定性拒绝。**

Cold recovery restores persisted active DAG runs after a Manager restart. Nodes that were RUNNING are marked FAILED to avoid unsafe duplicate execution. Therefore, failed=1 means one run was restor...
