## Backend Change Boundary

|
|
Domain: Banner (write + C-end read)
|
|
App: AdminHandler / HomeHandler → admin.Service / home → AdminRepo
|
|
API:
|
|
POST /api/v1/admin/cms/banners
|
|
PUT /api/v1/admin/cms/banners/{id}
|
|
GET /api/v1/home/banners?placement=home
|
|
Permission: admin.cms.write (additive); keep admin.cms.read
|
|
Audit: admin_audit_logs on POST/PUT
|
|
Table: reuse ops_banners (ECR-024)
|
|
```
|
|
|
|
## Out of boundary
|
|
|
|
FeedSlot 写 · ScheduledPublication 写 · UGC · 真支付 · soft-delete · Crisis/Handoff/ContentSafety 写 · 新 RBAC 子系统
|
|
|
|
## Rollback
|
|
|
|
1. migration down（撤权限种子）
|
|
2. 移除写路由与 C 端读取路由
|
|
3. H5 回退静态 `homeFeeds`
