 # Approved Plan Continuity Hard Gate
 
-A focused extraction of recent OpenClaw workflow hardening work around:
-- approved-plan continuity hard-gate
-- dispatch receipt binding
-- anti-blackhole / completion-delivery watchdog groundwork
+## 中文說明
 
-This repo was exported from a larger workspace to isolate the relevant implementation and tests.
+這個 repo 是從較大的 OpenClaw workspace 中抽出的焦點工作流成果，主題是：
+
+- **approved plan continuity hard-gate**
+- **dispatch receipt binding**
+- **anti-blackhole / completion-delivery watchdog groundwork**
+
+目標是避免這種情況再次發生：
+
+- 任務已完成
+- 下一步其實已經明確
+- 但沒有真的 dispatch 下一個 task
+- 最後流程卻還是收尾，造成 **auto-next break / continuity failure**
+
+目前 repo 內主要包含：
+
+- continuity gate 規則與測試
+- dispatch receipt binding 骨架與最小 receipt writer
+- anti-blackhole / delivery watchdog 的前置設計與基礎腳本
+- 相關 runbook / plan / state shape
+
+### 目前重點
+
+這個 repo 目前著重於把以下能力拆成可測試、可逐步落地的切片：
+
+1. **continuity hard-gate**
+   - approved plan 內 task 完成後，若沒有 next dispatch receipt，且狀態又不是 `waiting_user` / `blocked` / `pending_verification`，則不應允許正常收尾。
+
+2. **dispatch receipt binding**
+   - 不只知道 planner 推導出下一步，而是要真的留下可驗證的 dispatch receipt。
+
+3. **anti-blackhole groundwork**
+   - 為後續的 subagent completion-delivery watchdog 提供 receipt / state / failure mode 基礎。
+
+### 說明
+
+這是一個**聚焦匯出 repo**，不是整個原 workspace 的完整鏡像。目的是先把相關修補線獨立出來，方便：
+
+- 追蹤修補進度
+- 做 code review
+- 補 README / runbook / 測試
+- 後續再整合回主要流程

+## English Description
+
+This repository is a focused export from a larger OpenClaw workspace. It captures a workflow hardening workstream around:
+
+- **approved plan continuity hard-gate**
+- **dispatch receipt binding**
+- **anti-blackhole / completion-delivery watchdog groundwork**
+
+The goal is to prevent this failure mode:
+
+- a task is completed,
+- the next step is already known,
+- but the next task is never actually dispatched,
+- and the flow still closes out as if continuity were preserved.
+
+The repository currently includes:
+
+- continuity gate rules and tests
+- dispatch receipt binding skeletons and a minimal receipt writer
+- groundwork for anti-blackhole / delivery-watchdog handling
+- related runbooks, plans, and state-shape definitions
+
+### Current Focus
+
+This repo is currently structured to make the following capabilities testable and incrementally adoptable:
+
+1. **Continuity hard-gate**
+   - If a task inside an approved plan is marked complete, and there is no next dispatch receipt, and the closure state is not `waiting_user`, `blocked`, or `pending_verification`, the flow should not be allowed to close normally.
+
+2. **Dispatch receipt binding**
+   - It is not enough for the planner to derive a next action; that action must also produce verifiable dispatch evidence.
+
+3. **Anti-blackhole groundwork**
+   - The repo also lays groundwork for future subagent completion-delivery watchdog logic through receipt/state/failure-mode definitions.
+
+### Note
+
+This is a **focused export repository**, not a full mirror of the original workspace. The intent is to isolate the relevant hardening work so it can be:
+
+- reviewed more easily
+- iterated independently
+- documented clearly
+- integrated back into the main flow later
