# Handoff

**From:** ARCHITECT  
**To:** ENGINEER  
**ECR:** ECR-001  
**State:** design → ready_for_engineering（Phase A/B 待领取）  
**Date:** 2026-08-05  

## Artifacts

- [x] ECR (Approved) — `docs/ECR/ECR-001-structural-realignment.md`
- [x] PRODUCT_SPEC — `docs/PRODUCT_SPEC/ECR-001-structural-realignment.md`
- [x] ENGINEERING_SPEC — `docs/ENGINEERING_SPEC/ECR-001-structural-realignment.md`
- [x] RISK_REVIEW — N/A
- [x] IMPLEMENTATION_PLAN / TEST_PLAN — `docs/HANDOFF/ECR-001-implementation-plan.md`
- [x] TRACEABILITY updated
- [ ] TEST_REPORT / CODE_REVIEW — Engineer per Phase
- [x] ADR-0007 — `.ai/adr/0007-ess-ai-dual-track.md`

## Restrictions — Do not modify

- 公共 API URL / envelope
- 用户可见文案与交互语义（除非子 ECR）
- 技术栈与 monorepo 边界
- 一次 PR 多个 Phase
- `internal/star/fortune` 破坏性重命名（归 ECR-002）

## Goal for receiver

1. 领取 **Phase A**（文档对齐）或直接 **Phase B**（H5 拆页，推荐先做最大痛点）。
2. 为该 Phase 建 `docs/TASKS/TASK-*-ECR001-phaseX.yaml`，`role: engineer`。
3. 实现后：`ess-validate --phase coding` + 本仓 DoD Review Report。
4. 绿则更新 `docs/STATE/` owner → reviewer。

## Done for this hop

- [x] 架构诊断：全仓重写否决；分阶段结构对齐
- [x] ESS 工件齐备
- [x] 双轨 ADR Accepted
