+> 关联：[ops-scale-definition.md](ops-scale-definition.md) · [ops-content.md](ops-content.md)
+
+## 1. 目标
+
+运营可在 Explore 侧 **创建/更新量表元数据**（slug/title/description）；**上下架仍走 ECR-008**。Closed 后 STOP。
+
+## 2. In / Out
+
+| In | Out |
+|----|-----|
+| POST/PUT `/admin/explore/scales*` | **PATCH status**（ECR-008 独占） |
+| 复用 `admin.explore.write` | 题干 / scale_questions |
+| 复用表 `scales` | soft-delete · Prompt/Knowledge/Chunk |
+| 创建默认 `status=draft` | 支付 · UGC · 自动 ECR-047 |
+| 审计 | 新权限子系统 |
+
+## 3. 双通道矩阵（强制）
+
+| API | 权限 | 字段 |
+|-----|------|------|
+| `POST/PUT /admin/explore/scales*` | `admin.explore.write` | slug · title · description |
+| `PATCH /admin/scales/{id}` | `admin.content.write` | **仅 status**（既有） |
+
+## 4. Domain
+
+| 字段 | 规则 |
+|------|------|
+| `slug` | 唯一；`^[a-z][a-z0-9-]{1,62}$` |
+| `title` | 必填 · ≤128 |
+| `description` | ≤512 · 可空串 |
+| `status` | 创建固定 `draft`；本刀 PUT **不得**改 status |
+
+## 5. C 端可观察
+
+| 条件 | 行为 |
+|------|------|
+| 新建 draft | C 端 published list **不含** |
+| ECR-008 PATCH → published | C 端 list **含**（既有 `/scales`） |
+| 不新增 C 端路由 | — |
+
+## 6. Migration
+
+`000054`→`000055_ops_scale_definition_write`：幂等确认 `admin.explore.write`
+
+## 7. UI
+
+admin-h5：量表元数据页（新建/编辑 slug·title·description）；上下架仍在「内容」页。
+
+## 8. AC
+
+| ID | Then |
+|----|------|
+| AC-F-01 | POST → list/get 可见 · status=draft |
+| AC-F-02 | PUT 改 title → get 反映；status 不变 |
+| AC-F-03 | 重复 slug → 409 |
+| AC-F-04 | draft 不在 C 端 published list；PATCH published 后出现 |
+| AC-S-01/02 | 401；仅 read → POST 403 |
+| AC-A-01 | 写产生审计 |
+| AC-O-01 | explore PUT 带 status 被忽略或不接受；无题干写；无 soft-delete |
+
+## 9. Closed 后

+# ECR-046 Candidate Review — ExploreConfig · ScaleDefinition
+
+> **RESOLVED 2026-08-13（Human: Candidate Review → Auth/Spec/开码 → Closed）：**  
+> 首刀 = **ScaleDefinition 增量写** · **Closed** · Loop **STOP** · 禁自动 ECR-047  
+
+**Date:** 2026-08-13  
+**Mode:** Candidate Review **Approved** · Spec **Closed** · Coding **Closed**  
+**Anchors:** Next=`ECR-047`（禁自动开）· Max Migration=`000055`
+
+## 锁定现状
+
+| 项 | 状态 |
+|----|------|
+| ECR-041–045 | **CLOSED** · origin/main 齐平（至 045） |
+| ECR-008 | `PATCH /admin/scales/:id` · `admin.content.write` · **仅 status** · Live Promote **BLOCKED** |
+| ECR-040 | Explore scales **只读**（`explore.read` / `content.write`） |
+| Continuous Loop | **STOP**（045 Auth 耗尽） |
+| 硬 STOP | 支付 / UGC / soft-delete / Crisis·Handoff / Prompt / Knowledge / Chunk |
+
+## 相对 ECR-008 的增量边界（强制 · Spec 不得偏离）
+
+| 归属 | API | 权限 | 字段 |
+|------|-----|------|------|
+| **ECR-008（保持）** | `PATCH /admin/scales/{id}` | `admin.content.write` | **仅** `status` ∈ {published, draft} |
+| **ECR-046（新增）** | `POST/PUT /admin/explore/scales*` | `admin.explore.write` | **仅** `slug` · `title` · `description`（创建默认 `status=draft`） |
+
+**禁止：**
+
+- 在 explore 写路径改 `status`（避免双通道）  
+- 题干 / `scale_questions` CRUD  
+- `deleted_at` soft-delete  
+- 新建权限子系统  
+
+## 决议
+
+**ECR-046 = ExploreConfig · ScaleDefinition 元数据薄写面**
+
+拟议（Spec 细化）：
+
+- 复用表 `scales`  
+- 复用 `admin.explore.write`  
+- 审计 `explore.scale_definition.create|update`  
+- C 端：继续依赖 `status=published` 供给（由 ECR-008 PATCH 控制）；本刀可观察点 = admin 可创建/改元数据且 **不**绕过 content 上下架  
+- Migration：编码时占 **000055**（幂等确认 explore.write）  
+- Continuous Loop：**仅**单独 Auth 且 **仅限 ECR-046**；Closed → STOP · 禁自动 ECR-047  
+
+## 硬 STOP
+
+Prompt / Knowledge / Chunk · 支付 · UGC · soft-delete · Crisis/Handoff · 题干编辑 · 重复 status PATCH · ECR-008 Live Promote 解禁 · 自动下一刀  
+
+## 下一步（仍不写码）
+
+1. ~~Candidate Review approve · ScaleDefinition~~ **Done**  
+2. Human：批准 **ECR-046 专用** Write Authorization  
+3. Spec `ops-scale-definition-write` · ECR · BD（必须含上表增量矩阵）  
+4. 开码口令后才改 `apps/`  
+
+**本回合交付 = Candidate Review RESOLVED；无 Spec · 无 Auth Loop · 无 `apps/`。**
