+# HANDOFF — ECR-011 Architect → Engineer
+
+**Date:** 2026-08-12  
+**ECR:** ECR-011（**Approved** 2026-08-12）  
+**BD:** BD-2026-011 Approved  
+
+## Task interpretation
+
+补门禁并收敛 WIP：昵称 · 首页贴士 · Self 唯一/合盘交叉校验。  
+Human 已 Approve；按下方顺序对照 BD 收敛 → 测试产物 → Reviewer。不得扩大 Scope Forbidden。
+
+## Load
+
+1. `docs/ECR/ECR-011-identity-home-profile.md`  
+2. `docs/BACKEND_DESIGN/BD-2026-011-identity-home-profile.md`  
+3. `docs/ENGINEERING_SPEC/ECR-011-identity-home-profile.md`  
+4. Spec：`profile` · `star-profile` · `account-auth` · `home`  
+5. `docs/PROJECT_RULES.md` · `.ai/definition-of-done.md`  
+
+## Ordered plan（Approve 后）
+
+1. **冻结范围** — 仅 Workstream A/B/C；拒绝顺手改 Ops  
+2. **对照 BD** — migration / 40902 / synastry 校验 / PATCH me / daily-tips 与 OpenAPI 一致  
+3. **前端** — `authSession.ensure*`；合盘 `pickableProfiles` 仅 other；昵称卡；自己卡贴士  
+4. **测试** — nickname go test · Synastry/Profile/ImageCard vitest · 手工冒烟清单见下  
+5. **产物** — `docs/TEST_REPORT/ECR-011.md` · `docs/HANDOFF/ECR-011-engineer-to-reviewer.md` · 更新 STATE · TRACEABILITY  
+6. **Gate** — `ess-validate.py --phase coding --ecr ECR-011`  
+
+## Smoke checklist
+
+- [ ] 档案页仅 1 个「我」；合盘右侧无多个「我」  
+- [ ] 再跑解码不新增 self、不覆盖已改档案名  
+- [ ] 匹配/合盘同名同生日 TA 不刷屏  
+- [ ] 改昵称 → 首页「自己」标题更新  
+- [ ] 有生日 daily-tips；关 key 仍 fallback

+# HANDOFF — ECR-011 Engineer → Reviewer（re-submit）
+
+**From:** Engineer  
+**To:** Reviewer  
+**Date:** 2026-08-12

+## Fixed

+## Still SKIP locally
+
+Docker daemon 不可用 → integration 仍 SKIP。请 Reviewer 在有 Postgres 环境跑：

+cd apps/api && go test ./internal/integration/ -run TestECR011 -count=1 -v
+```

+# HANDOFF — ECR-011 Reviewer → Engineer（iterate）
+
+**From:** Reviewer  
+**To:** Engineer  
+**Date:** 2026-08-12  
+**Verdict:** Request changes（见 `docs/CODE_REVIEW/ECR-011.md`）  
+
+## Required fix
+
+1. 修正 `apps/api/internal/integration/ecr011_test.go`：断言 `clothing` / `palette` / `wellness`（勿用 `wear` / `colors`）  
+2. `npm run deps:up` 后 `go test ./internal/integration/ -run TestECR011 -count=1 -v` → PASS  
+3. 更新 `docs/TEST_REPORT/ECR-011.md`（integration 不再 SKIP/错断言）  
+4. 回交 Reviewer（STATE.owner=reviewer）  
+
+无 Scope 扩张。
