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

## 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
