# Feature Spec: 账户生命周期 / UserStatus( Ops · ECR-013B)
> Status: `Active`(契约定义)· Map: `§7 运营后台` · Phase: `Ops-D`
> Parent: **WAVE0-FROZEN** (`27f27a1`) · Predecessor: **ECR-013A Closed**
> ESS: `docs/ECR/ECR-013B-account-lifecycle.md`( Draft · Contract Definition · **禁止编码**)
> Capability: `AccountLifecycle` · BC: `Identity_Profile`
> 模板:`docs/WAVE0/contracts/OPS-CONTRACT-TEMPLATE.md`

## ESS 门禁
1. Change Level = **L2 ** → 须 ECR + BD **Approved ** 后方可改 `apps/`
2. **当前阶段:Contract Definition only ** ( Start Authorization 2026-08-07)— 禁止 migration / handler / DeviceAuth 改动
3. 实现轮:TEST_REPORT 映射全部 AC-ID · contract_diff · boundary-rules 复核

## L0 Capability
| 字段 | 内容 |
|------|------|
| Capability ID | `AccountLifecycle` |
| Purpose | 以可审计状态机管理 C 端用户账户启停与封禁,阻断违规会话 |
| Why now | `users.status` 字段已存在但无运营迁移与强制拒绝;013A 权限面就绪后可挂状态写权限 |
| Non-goals | soft-delete / `deleted` ;UGC 社区封禁;真支付;Admin 账号启停(已有 admin.status);推送通知 |
---
## L1 Bounded Context
| 字段 | 内容 |
|------|------|
| Primary BC | `Identity_Profile` |
| owns | `User` · `UserStatus` · `AccountStateTransition` |
| does_not_own | `AdminRole` · `Membership` · `Payment` · `BanRecord` ( Account_Risk 后置加深) |
| allowed | `Admin_Auth_Audit.write_audit` (经 admin 调用) |
| forbidden | `Payment` · `Membership.write` · soft-delete User |
权威:`.ai/domain/boundary-rules.md` · `Account_Risk` 仅允许经明确服务触发 `UserStatus.transition` 。
---
## 1. 功能定义
| 字段 | 内容 |
|------|------|
| Name | Account Lifecycle / UserStatus |
| Purpose | 运营可迁移用户状态;非 active 会话在 C 端被拒绝 |
| Business Goal | 风险处置最小闭环,不引入社区/UGC |
| In | Out |
|---|---|
| 状态机 `active/disabled/banned/suspended` | soft-delete / GDPR 擦除 |
| Admin 迁移 API + AuditLog + Transition 记录 | 站内推送 / 短信 |
| DeviceAuth / Bearer 对非 active 拒绝 | AdminAccount.status( 013A 外) |
| 权限码 `admin.users.status.write` | 行级数据 ACL |
---
## L2 Domain
| Entity | 不变式 / 状态机 |
|--------|----------------|
| `UserStatus` | 取值冻结:`active` · `disabled` · `banned` · `suspended` ;非法值拒写 |
| `User.status` | 与 `UserStatus` 同值;默认 `active` (已有列) |
| `AccountStateTransition` | 只追加;记录 from→to · admin_id · reason · created_at |
### 合法迁移
``` text
active → disabled | banned | suspended
disabled → active | banned
suspended → active | banned | disabled
banned → active | disabled
```
其它边 → **400 ** 。同状态写 → **400 ** (幂等拒绝,避免空审计噪音)。
### C 端效应
| Status | DeviceAuth / 已登录 Bearer |
|--------|------------------------------|
| `active` | 放行 |
| `disabled` / `banned` / `suspended` | **401 ** (或 403 统一码,实现轮定一)+ 不可发新 session |
---
## L3 API Contract(意图 · 实现轮同步 OpenAPI)
前缀:`/api/v1/admin` · AdminAuth · 信封 `{code,message,data}`
| Method | Path | 权限 | 语义 |
|--------|------|------|------|
| POST | `/users/:id/status` | `admin.users.status.write` | 迁移 UserStatus;写 Transition + AuditLog |
| GET | `/users/:id/status-transitions` | `admin.users.read` | 最近迁移列表(limit) |
既有 `GET /users` · `GET /users/:id` 已暴露 `status` — 保持;实现轮确认枚举文档化。
`contract_diff` : `docs/CONTRACT_DIFF/ECR-013B.yaml`
RBAC catalog **additive ** : `admin.users.status.write` → 种子写入 `super_admin` ( migration)。

## L4 Acceptance Criteria
### Functional
| ID | Given | When | Then |
|----|-------|------|------|
| AC-F-01 | 用户 `active` | POST status=`banned` + reason | 200; GET user.status=`banned` |
| AC-F-02 | 用户 `banned` | POST status=`active` | 200;可再次 DeviceAuth |
| AC-F-03 | 非法边(如 `active` →`active` ) | POST | **400 ** |
| AC-F-04 | GET status-transitions | — | 含最近 from/to/admin/reason |
### Security
| ID | Given | When | Then |
|----|-------|------|------|
| AC-S-01 | Admin 无 `admin.users.status.write` | POST status | **403 ** + deny audit |
| AC-S-02 | 用户 `banned` | C 端带原 Bearer 访问受保护 API | **401/403 ** |
| AC-S-03 | 仅 DeviceAuth 无 Admin | POST `/admin/users/:id/status` | **401 ** |
| AC-S-04 | 无 Admin session | GET transitions | **401 ** |
### Performance
| ID | Given | When | Then |
|----|-------|------|------|
| AC-P-01 | transitions ≤1000 行/用户 | GET transitions limit=50 | 本机 P95 * * < 500ms** |
### Observability
| ID | Given | When | Then |
|----|-------|------|------|
| AC-O-01 | 迁移成功 | — | AuditLog action=`users.status.transition` |
| AC-O-02 | 迁移成功 | — | `account_state_transitions` 有对应行 |

## Forbidden(本切片)
- soft-delete / `deleted` 状态
- 真支付 · UGC · Prompt · 兑换码 · Crisis 深化
- 改 Admin RBAC 模型(仅 **additive ** 一枚 permission)
- 自动开下一 ECR

## Implementation Notes(实现轮才执行)
| 项 | 内容 |
|----|------|
| Migration | YES( transitions 表;permission 种子;必要时 CHECK/注释枚举) |
| Packages | service account/lifecycle · DeviceAuth/session 拒绝 · admin handler · admin-h5 用户详情最小 CTA |
| Depends | ECR-013A Closed( permission middleware) |
