+# Feature Spec: OpsCMS · FeedSlot 写面（Ops · ECR-042）
+
+> Status: `Active`（**ECR-042 Closed**）  
+> Map: `§7` · Capability: `OpsCMS` · BC: `Ops_CMS_NoUGC`  
+> Write-Wave: `docs/WAVE0/WRITE_WAVE_AUTHORIZATION.md`  
+> Predecessor: ECR-025 Closed · ECR-041 Closed  
+
+## Goal
+
+运营可创建/更新/上下架 FeedSlot；C 端可读 active 槽位；首页主信息流区按 `home.main`（或 placement=home 的 active 槽）显隐；失败回退「仍展示推荐区」。
+
+## In / Out
+
+| In | Out |
+|----|-----|
+| Admin POST/PUT feed-slots · `admin.cms.write` | Banner 再扩 · ScheduledPublication 写 |
+| C 端 GET `/home/feed-slots` | UGC 内容流正文 CMS · soft-delete |
+| 首页：无 active home 槽 → 隐藏推荐区；API 失败 → 仍显示 | 真支付 · Crisis/Handoff · 新权限模型 |
+
+## Domain
+
+复用 `ops_feed_slots`：`code` 唯一 · `slot_key` · `placement` ∈ {home,explore,ask} · `active` · `system`（system 不可改 code）。
+
+## API
+
+| Method | Path | Perm |
+|--------|------|------|
+| GET | `/admin/cms/feed-slots*` | cms.read |
+| POST/PUT | `/admin/cms/feed-slots*` | cms.write |
+| GET | `/home/feed-slots?placement=home` | DeviceAuth |
+
+无 DELETE；下架 `active=false`。
+
+## AC
+
+AC-F create/update/conflict/invalid · AC-S 401/403 · AC-A audit · AC-C 首页显隐与失败回退 · AC-O 无 Banner 合并 / 无 soft-delete  
+
+## Migration
+
+无新表；权限已在 `000051`。本切片 **不新增 migration 文件**（Max 保持 `000051`）。
