# 举报与反馈系统实现计划

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** 在 TopFans 平台新增内容举报与用户反馈两大工单系统（客户端提交 + 后台审核处理 + 自动隐藏阈值闭环）

**Architecture:**
- 独立 Go Dubbo 微服务 `moderationService`（端口 20010）承载客户端 API + 自动隐藏阈值触发
- 共享 PostgreSQL `top-fans` 库 9 张表；Redis 计数；OSS 证据图上传
- `TopFans-activity-admin` 后台（FastAPI + Vue3）独立读写共享库做审核动作
- 业务表软删除（`is_active` + `deleted_at`）承担下架/封禁，`moderation_target_status` 仅做审计 + 警告状态

**Tech Stack:** Go 1.21+ / Dubbo-go / GORM / PostgreSQL 16 / Redis 7 / FastAPI / SQLAlchemy / Vue3 + Element Plus / uni-app + uView 2.x

**参考 spec:** `docs/superpowers/specs/2026-06-11-moderation-report-feedback-design.md` (v2.5)

**子计划拆分建议**（scope check）：本计划跨 2 个仓库、5 种技术栈、11 阶段。建议在执行时按仓库拆分为 4 个独立执行计划：

| 子计划 | 阶段 | 仓库 | 工作目录 |
|--------|------|------|---------|
| A: 主仓数据库 + Go 微服务 | 1, 2, 6 | topfans 主仓 | `TopFansByGithub` |
| B: 后台 API + 前端 | 3, 4 | TopFans-activity-admin | `TopFans-activity-admin` |
| C: 客户端集成 | 5 | topfans 主仓 `frontend/` | `TopFansByGithub` |
| D: 通知 + 测试 | 7 | 两仓并行 | - |

**约束（来自 CLAUDE.md + 设计文档）：**
- ✅ 任何手动指定 ID 的 INSERT 必须 `SELECT setval('xxx_id_seq', (SELECT MAX(id) FROM xxx))`
- ✅ 不主动 commit，等用户明确指示
- ✅ 错误处理统一错误码（50001-50019）+ 友好提示 + 日志
- ✅ 自审修复后做整体回归检查

## 阶段 1：数据库 Schema（topfans 主仓）

### Task 1.1: 创建迁移文件

**Files:**
- Create: `backend/migrations/2026_06_11_011_moderation_tables.sql`

**前置：**
- 已有 `2026_06_08_010_statistic_partitions_initial.sql`；新文件按三位编号递增到 011
- 注意：`2026_06_16_001_create_notifications.sql` 已存在，本 plan 用 011 不冲突（不同日期段）

- [ ] **Step 1: 写完整 SQL 迁移**

按 spec §3 写入 9 张表的 CREATE TABLE + 索引 + 种子数据 + 9 个序列同步。

**关键 SQL 模板**（完整内容按 spec §3.2-3.10 复制，9 张表全部带 `COMMENT ON TABLE` 文档注释）：

```sql
-- ============================================================================
-- 举报与反馈系统 (spec: docs/superpowers/specs/2026-06-11-moderation-report-feedback-design.md v2.5)
-- 9 张表 + 索引 + 种子数据 + 序列同步
-- 所有 *_at 字段均为 Unix 毫秒 (BIGINT)，与 Go time.Now().UnixMilli() 一致
-- ============================================================================

-- 1. report_categories (举报分类)
CREATE SEQUENCE report_categories_id_seq START WITH 10000 OWNED BY report_categories.id;
CREATE TABLE report_categories (
    id BIGSERIAL PRIMARY KEY,
    code VARCHAR(50) NOT NULL UNIQUE,
    name VARCHAR(50) NOT NULL,
    description VARCHAR(200),
    severity SMALLINT NOT NULL DEFAULT 1,
    enabled BOOLEAN NOT NULL DEFAULT TRUE,
    sort_order INT NOT NULL DEFAULT 0,
    created_at BIGINT NOT NULL,
    updated_at BIGINT NOT NULL,
    CONSTRAINT chk_report_categories_severity CHECK (severity BETWEEN 1 AND 5)
);
COMMENT ON TABLE report_categories IS '举报分类字典（动态配置，enabled=FALSE 不下发客户端）';
CREATE INDEX idx_report_categories_enabled ON report_categories(enabled, sort_order);

INSERT INTO report_categories (code, name, description, severity, sort_order, created_at, updated_at) VALUES
  ('pornographic', '色情低俗', '含裸露、性暗示内容', 5, 1, EXTRACT(EPOCH FROM NOW())*1000, EXTRACT(EPOCH FROM NOW())*1000),
  ('violence',    '暴力血腥',  '含暴力、血腥画面', 5, 2, EXTRACT(EPOCH FROM NOW())*1000, EXTRACT(EPOCH FROM NOW())*1000),
  ('infringing',  '侵权盗版',  '侵犯他人著作权/商标权', 4, 3, EXTRACT(EPOCH FROM NOW())*1000, EXTRACT(EPOCH FROM NOW())*1000),
  ('false_info',  '虚假信息',  '虚假、欺骗性内容', 3, 4, EXTRACT(EPOCH FROM NOW())*1000, EXTRACT(EPOCH FROM NOW())*1000),
  ('political',   '政治敏感',  '涉及政治敏感话题', 5, 5, EXTRACT(EPOCH FROM NOW())*1000, EXTRACT(EPOCH FROM NOW())*1000),
  ('ad_spam',     '广告骚扰',  '垃圾广告、骚扰信息', 2, 6, EXTRACT(EPOCH FROM NOW())*1000, EXTRACT(EPOCH FROM NOW())*1000),
  ('other',       '其他',      '其他违规情况', 1, 99, EXTRACT(EPOCH FROM NOW())*1000, EXTRACT(EPOCH FROM NOW())*1000);
SELECT setval('report_categories_id_seq', (SELECT MAX(id) FROM report_categories));
```

按相同模式写 `feedback_categories` / `reports` / `report_evidence` / `feedbacks` / `feedback_evidence` / `moderation_actions` / `moderation_target_status` / `admin_audit_logs` 8 张表 + 各自序列同步（**每张表末尾必须 `SELECT setval`** — CLAUDE.md 强制）。

**关键约束清单**（必填）：
- `reports.chk_reports_status` 含 `'withdrawn'` / `'archived'`（spec §3.4 v2.4 V2 修复）
- `moderation_actions.chk_moderation_actions_action_type` 含 `'autohide_noop'` / `'withdraw'` / `'force_release'`（v2.4 V3）
- `moderation_actions.chk_moderation_actions_admin_id` 含 `(admin_id >= 0)`（v2.2 B4 系统自动 sentinel）
- `moderation_target_status.chk_mts_last_action_type` 含 `'warn_cleared'`（v2.4 V4）
- `chk_mts_warn_fields` 第 3 子句支持"历史警告已清除"（v2.7 H2）
- `uk_reports_reporter_target_pending` 唯一索引（防重复）

**关键索引**：
- `idx_reports_status_created (status, created_at DESC)`
- `idx_reports_triggered_autohide (target_type, target_id, created_at DESC) WHERE triggered_auto_hide=TRUE`（v2.5 W2）
- `idx_moderation_actions_target (target_type, target_id, created_at DESC) WHERE target_type IS NOT NULL`（v1.7 H1 修复）
- `idx_feedbacks_claimed_by (claimed_by, status, created_at DESC) WHERE claimed_by IS NOT NULL`

- [ ] **Step 2: 验证 SQL 语法**

```bash
# 用 docker 起临时 PG 验证
docker run -d --name pg-verify -e POSTGRES_PASSWORD=test -p 15433:5432 postgres:16
sleep 3
PGPASSWORD=test psql -h localhost -p 15433 -U postgres -d postgres -f backend/migrations/2026_06_11_011_moderation_tables.sql
# 期望：所有 CREATE/INSERT/setval 都成功，无 CHECK 违例
docker rm -f pg-verify
```

- [ ] **Step 3: 验证 9 个序列都同步**

```sql
SELECT sequencename, last_value,
       (SELECT MAX(id) FROM report_categories) AS table_max_id
FROM pg_sequences WHERE sequencename LIKE '%moderation%' OR sequencename LIKE '%reports%' OR ...;
-- 所有 last_value >= MAX(id)
```

- [ ] **Step 4: 暂不 commit（CLAUDE.md 规定不主动 commit）**

---

### Task 1.2: 写 integration test 验证约束

**Files:**
- Create: `backend/services/moderationService/repository/moderation_repository_test.go`（前置创建空文件）

- [ ] **Step 1: 写测试用例覆盖关键 CHECK 约束**

使用 testcontainers-go 起临时 PG（参考 spec §7.4 隔离策略），加载阶段 1.1 迁移后跑：

```go
func TestReports_WithdrawnStatus_Allowed(t *testing.T) {
    // 测试 chk_reports_status 包含 'withdrawn'
    db.Exec(`UPDATE reports SET status='withdrawn' WHERE id=?`, id)
    // 期望：无 CHECK 违例
}

func TestReports_DuplicatePending_Blocked(t *testing.T) {
    // 测试 uk_reports_reporter_target_pending 唯一索引
    db.Exec(`INSERT INTO reports (...) VALUES (...)`)
    db.Exec(`INSERT INTO reports (...) VALUES (...)`) // 同 reporter+target pending
    // 期望：第二次 INSERT 失败 unique violation
}

func TestModerationActions_AdminIDZero_Allowed(t *testing.T) {
    // 测试 chk_moderation_actions_admin_id (admin_id >= 0)
    db.Exec(`INSERT INTO moderation_actions (..., admin_id=0, ...)`)
    // 期望：成功（0 是 sentinel）
}

func TestMTS_WarnClearedPreservesHistory(t *testing.T) {
    // 测试 chk_mts_warn_fields 第 3 子句
    db.Exec(`UPDATE moderation_target_status SET is_warned=FALSE, warn_count=3, last_warned_at=$now WHERE target_id=?`)
    // 期望：成功（保留 warn_count + last_warned_at）
}
```

- [ ] **Step 2: 跑测试**

```bash
cd backend/services/moderationService
go test ./repository/... -run TestReports -v
```

- [ ] **Step 3: 暂不 commit**

---

## 阶段 2：Go moderationService 微服务

### Task 2.1: 创建服务目录骨架

**Files:**
- Create: `backend/services/moderationService/main.go` 等所有空文件 + `go.mod`
- Modify: `backend/go.work`

**参考模式：** 复制 `backend/services/socialService/` 全部结构，改服务名为 `moderation-service`。

- [ ] **Step 1: 创建目录与 go.mod**

```bash
cd backend/services
cp -r socialService moderationService
cd moderationService
# 替换所有 "socialService" / "social" / "socialService" 为 "moderationService" / "moderation"
# 端口 20002 → 20010
# Dubbo 服务名 SocialService → ModerationService
```

- [ ] **Step 2: 修改 go.work**

在 `backend/go.work` 中追加：
```
	./services/moderationService
```

- [ ] **Step 3: 编译验证**

```bash
cd backend/services/moderationService
go mod tidy
go build -o moderationService main.go
# 期望：编译通过
```

---

### Task 2.2: 写 proto 定义

**Files:**
- Create: `backend/proto/moderation.proto`

**关键 RPC**（按 spec §5.1 客户端 API）：
- `GetReportCategories` / `GetFeedbackCategories`
- `SubmitReport(SubmitReportRequest) returns (SubmitReportResponse)`
- `ListMyReports(ListMyReportsRequest) returns (ListMyReportsResponse)`
- `GetReport(GetReportRequest) returns (GetReportResponse)`
- `SubmitFeedback / ListMyFeedbacks / GetFeedback`

**关键字段**：
```proto
message SubmitReportRequest {
  string target_type = 1;  // asset | user_profile
  int64 target_id = 2;
  string category_code = 3;
  string description = 4;  // <= 500
  bool is_anonymous = 5;
  repeated string evidence_keys = 6;  // OSS keys, <= 5
}
message SubmitReportResponse {
  int64 report_id = 1;
  string status = 2;  // pending | auto_hidden
  bool auto_hidden = 3;
  bool target_hidden = 4;  // 本次 auto-hide 是否执行了 UPDATE
  int64 claimed_by = 5;     // 新工单始终 0
  int64 claimed_at = 6;
  int64 created_at = 7;
}
```

- [ ] **Step 1: 写 proto 文件**（按 spec §5.1 完整字段）

- [ ] **Step 2: 编译生成 .pb.go 和 .triple.go**

```bash
cd backend
# 参考现有 proto 编译流程
make proto-gen  # 或按 gen-swagger.sh 同等脚本
```

- [ ] **Step 3: 验证生成产物**

```bash
ls backend/pkg/proto/moderation/
# 期望：moderation.pb.go + moderation.triple.go 都在
```

---

### Task 2.3: 写 ORM 模型

**Files:**
- Create: `backend/pkg/models/moderation.go`

**关键模型**（按 spec §3 表结构）：
```go
type Report struct {
    ID                 int64  `gorm:"primaryKey"`
    ReporterID         int64
    StarID             *int64
    TargetType         string // asset | user_profile
    TargetID           int64
    TargetSnapshot     datatypes.JSON
    TriggeredAutoHide  bool
    CategoryCode       string
    Description        string
    IsAnonymous        bool
    Status             string // pending | reviewing | auto_hidden | resolved | dismissed | withdrawn
    IsAutoHidden       bool
    ClaimedBy          *int64
    ClaimedAt          *int64
    ResolvedAction     *string
    ResolvedBy         *int64
    ResolvedAt         *int64
    ResolutionNote     *string
    CreatedAt          int64
    UpdatedAt          int64
}
// 同模式：ReportEvidence / Feedback / FeedbackEvidence / ModerationAction / ModerationTargetStatus / AdminAuditLog
```

**注意：** `*int64` 表示可空指针，对应 NULL 列。

---

### Task 2.4: 写仓储层 + 单测

**Files:**
- Create: `backend/services/moderationService/repository/moderation_repository.go`

**关键方法**：
- `CreateReport(ctx, tx, report) error`
- `GetReportByID(ctx, id) (*Report, error)`
- `ClaimReport(ctx, tx, id, adminID, now) (claimed bool, error)` —— 用 affected rows 判断抢锁
- `ReleaseReport(ctx, tx, id, adminID, now) error`
- `DismissReportPathA(ctx, tx, id, adminID, now) error` —— pending → dismissed 快速通道
- `DismissReportPathB/C/D(ctx, tx, id, adminID, now, restore bool) error`
- `ResolveReport(ctx, tx, id, action, adminID, note, now) error`
- `ListReports(ctx, filters) ([]*Report, error)`
- `BulkDismissReports(ctx, tx, ids, adminID, reason, now) (successCount int, error)`
- `ForceReleaseReport(ctx, tx, id, operatorAdminID, reason, now) error`
- 同模式：`feedback_repository.go`

**关键 SQL 模式**：
```go
// Claim - 用 affected rows 判定
res := tx.Model(&Report{}).
    Where("id = ? AND status IN ?", id, []string{"pending", "auto_hidden"}).
    Updates(map[string]interface{}{"status": "reviewing", "claimed_by": adminID, "claimed_at": now})
if res.Error != nil { return false, res.Error }
return res.RowsAffected == 1, nil
```

- [ ] **Step 1: 写仓储层**

- [ ] **Step 2: 写仓储测试**（testcontainers 启临时 PG）

- [ ] **Step 3: 跑测试**

```bash
cd backend/services/moderationService
go test ./repository/... -v
# 期望：全部 PASS
```

---

### Task 2.5: 写 Service 层

**Files:**
- Create: `backend/services/moderationService/service/{report,feedback,category,auto_hide,transaction_helper}_service.go`
- Create: `backend/services/moderationService/service/lua/auto_hide.lua`

**关键方法**：

**`report_service.go`** — `SubmitReport`（spec §6.1 完整 7 步）：
```go
func (s *ReportService) SubmitReport(ctx, req) (*SubmitReportResponse, error) {
    // 0. 限流：每用户/IP/device 每天 30/200/200 次
    // 1. 验证分类、target_type、description、evidence
    // 2. 验证目标存在（assetClient.GetAssetRPC / userClient.GetUserRPC）
    // 2.5 自举报拦截：reporter_id != owner_uid(target)
    // 3. 防重复：uk_reports_reporter_target_pending
    // 4. 写 reports (status='pending', claimed_by/claimed_at=NULL)
    // 5. 写 report_evidence
    // 6. Redis Lua 计数 → 触发自动隐藏
    //    → 事务内：业务表软删除 + reports UPDATE auto_hidden + mts UPSERT + moderation_actions 流水
    // 7. 返回 SubmitReportResponse
}
```

**`auto_hide_service.go`** — Lua 脚本（spec §6.4）：
```lua
-- KEYS[1]=counter, KEYS[2]=user_marker
-- ARGV[1]=threshold, ARGV[2]=ttl_counter, ARGV[3]=ttl_marker
local first = redis.call('SET', KEYS[2], '1', 'NX', 'EX', ARGV[3])
if not first then
  return {0, tonumber(redis.call('GET', KEYS[1]) or '0')}
end
local n = redis.call('INCR', KEYS[1])
if n == 1 then
  redis.call('EXPIRE', KEYS[1], ARGV[2])
end
if n >= tonumber(ARGV[1]) then
  return {1, n}
end
return {0, n}
```

使用 `//go:embed` 加载：
```go
//go:embed lua/auto_hide.lua
var autoHideLuaScript string
```

**`auto_hide_service.go`** — 锁管理（spec §6.4）：
```go
func (s *AutoHideService) tryAutoHide(ctx, targetType, targetID, triggerReportID) error {
    ok, _ := s.redis.SetNX(ctx, "mod:report:lock:"+targetType+":"+targetID, "1", 5*time.Second)
    if !ok { return nil }  // 5s 内已有并发请求
    defer s.redis.Del(ctx, "mod:report:lock:"+targetType+":"+targetID)

    triggered, count := s.redis.Eval(ctx, autoHideLuaScript, ...).Result()
    if triggered.(int64) != 1 { return nil }

    // 事务内：业务表软删除 + reports UPDATE + mts UPSERT + moderation_actions 流水
    return s.txHelper.WithTx(ctx, func(tx *gorm.DB) error {
        // ① 业务表软删除（按 target_type 路由）
        var affected int64
        if targetType == "asset" {
            tx.Model(&models.Asset{}).Where("id = ? AND is_active = true", targetID).
                Updates(map[string]interface{}{"is_active": false, "deleted_at": now})
            affected = tx.RowsAffected
        } else { ... }

        // ② reports UPDATE pending → auto_hidden
        tx.Model(&models.Report{}).
            Where("target_type = ? AND target_id = ? AND status = 'pending'", targetType, targetID).
            Updates(map[string]interface{}{
                "status": "auto_hidden",
                "is_auto_hidden": true,
                "triggered_auto_hide": gorm.Expr("(id = ?)", triggerReportID),
            })

        // ③ mts UPSERT
        tx.Clauses(clause.OnConflict{...}).Create(&models.ModerationTargetStatus{...})

        // ③.5 写 moderation_actions 流水
        actionType := "takedown"
        if affected == 0 { actionType = "autohide_noop" }
        tx.Create(&models.ModerationAction{
            ReportID: triggerReportID, AdminID: 0, ActionType: actionType,
            TargetType: targetType, TargetID: targetID,
            Note: "auto-hide threshold reached", Success: true, CreatedAt: now,
        })

        return nil
    })
}
```

**`feedback_service.go`** — 状态机 + claimed_* 一致性（spec §6.3）：
- `SubmitFeedback` / `ListMyFeedbacks` / `GetFeedback`
- `ClaimFeedback` (认领) / `ReleaseFeedback` (释放，清 claimed_*)
- `ReplyFeedback` (终态，清 claimed_*) / `CloseFeedback` (终态，清 claimed_*) / `ArchiveFeedback` (终态，清 claimed_*)

**关键一致性**（spec §4.2 chk_feedbacks_claimed_pair）：所有终态迁移必须同时清 `claimed_by=NULL, claimed_at=NULL`。

- [ ] **Step 1: 写 transaction_helper.go**

```go
func (h *TxHelper) WithTx(ctx context.Context, fn func(*gorm.DB) error) error {
    return h.db.WithContext(ctx).Transaction(fn)
}
```

### Task 2.6: 写 Client 层（RPC 客户端）

**Files:**
- Create: `backend/services/moderationService/client/{asset,user,notification,redis}_client.go`

**关键实现**：
- `asset_client.go` — Dubbo 调用 `assetService.GetAssetRPC` 验证目标存在
- `user_client.go` — Dubbo 调用 `userService.GetUserRPC`
- `notification_client.go` — Dubbo 调用 `notificationService.SendNotification`（阶段 7.1 替换 stub 为真实现）
- `redis_client.go` — 初始化 Redis 客户端（参考 `aiChatService/main.go`）

**参考：** `backend/services/socialService/client/user_rpc_client.go`

---

### Task 2.7: 写 Provider 层（Dubbo 注册）

**Files:**
- Create: `backend/services/moderationService/provider/moderation_provider.go`

**关键实现**（参考 `social_provider.go`）：
```go
type ModerationProvider struct {
    pb.UnimplementedModerationServiceServer
    reportSvc   *service.ReportService
    feedbackSvc *service.FeedbackService
    categorySvc *service.CategoryService
}

func (p *ModerationProvider) SubmitReport(ctx, req) (*pb.SubmitReportResponse, error) {
    return p.reportSvc.SubmitReport(ctx, req)
}
// ... 其他 RPC 方法映射
```

- [ ] **Step 1: 写 provider**

- [ ] **Step 2: 在 main.go 注册 provider**

---

### Task 2.8: 完善 main.go 与启动脚本

**Files:**
- Modify: `backend/services/moderationService/main.go`
- Create: `backend/services/moderationService/start.sh`
- Create: `backend/services/moderationService/configs/dubbo.yaml`

**main.go** — 参考 `socialService/main.go`，加：
- 端口 20010
- `notificationServiceURL=tri://localhost:20008`（不指定 moderationService 自指）
- `DUBBO_USER_SERVICE_URL` / `DUBBO_ASSET_SERVICE_URL` / `DUBBO_NOTIFICATION_SERVICE_URL`
- 注册 Prometheus `/metrics`
- 注册 13+ 业务指标（spec §11.3）

**start.sh** — spec §10 阶段 2.1 模板（PORT/DB/REDIS/DUBBO 全 env）

- [ ] **Step 1: 写 main.go + start.sh + dubbo.yaml**

- [ ] **Step 2: 编译验证**

```bash
cd backend/services/moderationService
./start.sh  # 期望：build + start 成功，监听 20010
```

- [ ] **Step 3: metrics 端点验证**

```bash
curl http://localhost:20010/metrics | head -20
# 期望：promhttp 输出 + 自定义指标
```

---

### Task 2.9: Gateway 集成（HTTP 路由 + 客户端）

**Files:**
- Create: `backend/gateway/{controller,client,dto}/moderation_*.go`
- Modify: `backend/gateway/router/router.go`

**关键实现**（参考 `backend/gateway/controller/social_controller.go`）：

**`moderation_controller.go`**：
```go
type ModerationController struct {
    client *moderationClient.Client
}

func NewModerationController(cli *client.Client) (*ModerationController, error) {
    moderationCli, err := moderationClient.NewModerationClient(cli)
    if err != nil { return nil, err }
    return &ModerationController{client: moderationCli}, nil
}

func (c *ModerationController) SubmitReport(ctx *gin.Context) {
    var req dto.SubmitReportRequestDTO
    if err := ctx.ShouldBindJSON(&req); err != nil {
        ctx.JSON(400, dto.ErrorResponse{Code: 50005, Message: "描述过长（>500 字）"})
        return
    }
    resp, err := c.client.SubmitReport(ctx, converter.ToRPCSubmitReport(req))
    if err != nil { /* 错误码映射 */ }
    ctx.JSON(200, converter.FromRPCSubmitReport(resp))
}
```

**`router.go`** 新增（spec §阶段 2.10）：
```go
v1.GET("/moderation/report-categories", moderationController.GetReportCategories)
v1.GET("/moderation/feedback-categories", moderationController.GetFeedbackCategories)
v1.POST("/moderation/reports", moderationController.SubmitReport)
v1.GET("/moderation/reports", moderationController.ListMyReports)
v1.GET("/moderation/reports/:id", moderationController.GetReportDetail)
v1.POST("/moderation/feedbacks", moderationController.SubmitFeedback)
v1.GET("/moderation/feedbacks", moderationController.ListMyFeedbacks)
v1.GET("/moderation/feedbacks/:id", moderationController.GetFeedbackDetail)
```

- [ ] **Step 1: 写 controller + dto + converter + client**

- [ ] **Step 2: 在 router.go 注册路由**

- [ ] **Step 3: 启动 gateway，curl 验证**

```bash
curl -X POST http://localhost:8080/api/v1/moderation/reports \
  -H "Authorization: Bearer $TOKEN" \
  -d '{"target_type":"asset","target_id":12345,"category_code":"pornographic","description":"test","is_anonymous":false,"evidence_keys":[]}'
# 期望：返回 report_id
```

---

### Task 2.10: 完善 main.go / docker / Makefile

**Files:**
- Modify: `docker/Dockerfile.services` / `docker/docker-compose.local.yml` / `docker/docker-compose.prod.yml` / `Makefile`

**关键改动**：
- Dockerfile 加 `moderationservice` 构建阶段
- docker-compose 加服务定义（端口 20010、env）
- Makefile 加 `start-moderationservice` target

---

## 阶段 3：TopFans-activity-admin 后台 FastAPI

### Task 3.1: 创建模型 / Schema / CRUD

**Files:**
- Create: `backend/models/moderation.py`
- Create: `backend/schemas/moderation.py`
- Create: `backend/crud/moderation_crud.py`

**关键模型**（9 张表对应 SQLAlchemy ORM，按 spec §3 表结构）：
```python
class Report(Base):
    __tablename__ = "reports"
    id = Column(BigInteger, primary_key=True)
    reporter_id = Column(BigInteger, nullable=False)
    star_id = Column(BigInteger)
    target_type = Column(String(30), nullable=False)
    target_id = Column(BigInteger, nullable=False)
    target_snapshot = Column(JSON, nullable=False)
    triggered_auto_hide = Column(Boolean, default=False)
    # ... 其他字段
```

**关键 CRUD 函数**：
- `list_reports(filters, page) -> (rows, total)`
- `get_report_detail(id) -> Report`
- `claim_report(id, admin_id, now) -> bool`（用 affected rows 抢锁）
- `release_report(id, admin_id, now)`
- `execute_action(id, action, admin_id, note, now)` —— 4 条 dismiss 路径 + takedown/ban/warn/restore
- `bulk_dismiss_reports(ids, admin_id, reason, now) -> int`
- `force_release_report(id, operator_admin_id, reason, now)`
- `clear_warn(user_id, admin_id, reason, now)` —— warn_cleared 流程
- 同模式：`feedback_crud.py`

- [ ] **Step 1: 写 ORM**

- [ ] **Step 2: 写 Pydantic Schema**

- [ ] **Step 3: 写 CRUD 函数**

---

### Task 3.2: 写 Handler（FastAPI 路由）

**Files:**
- Create: `backend/handlers/moderation_admin.py`

**关键端点**（spec §5.2）：
- `GET /api/admin/moderation/reports` —— 列表（filter: status/category/target_type/keyword/page/page_size）
- `GET /api/admin/moderation/reports/{id}` —— 详情
- `POST /api/admin/moderation/reports/{id}/claim` —— 认领
- `POST /api/admin/moderation/reports/{id}/release` —— 释放
- `POST /api/admin/moderation/reports/{id}/actions` —— 审核动作
- `POST /api/admin/moderation/reports/bulk-dismiss` —— 批量驳回
- `POST /api/admin/moderation/reports/{id}/force-release` —— 强制释放
- `POST /api/admin/moderation/users/{id}/clear-warn` —— 清除警告
- `GET/POST/PUT/DELETE /api/admin/moderation/report-categories` —— 分类 CRUD
- 同模式：feedback endpoints
- `GET /api/admin/moderation/stats` —— 看板

**关键依赖**：
- `Depends(verify_token)` —— 复用现有 JWT 校验
- 解析 token → `(admin_id, role, exp)`，`admin_id` 写入 `moderation_actions.admin_id` / `admin_audit_logs.admin_id`

**关键错误处理**（50008 vs 50009 vs 50014 区分 — spec §7）：
```python
# claim 0 行匹配时二次 SELECT 查 status
result = await db.execute(update(Report).where(Report.id == id, Report.status.in_(['pending','auto_hidden'])).values(status='reviewing', ...))
if result.rowcount == 0:
    cur = await db.execute(select(Report).where(Report.id == id))
    row = cur.scalar_one_or_none()
    if row is None:
        raise HTTPException(404, detail={"code": 50007, "message": "工单不存在"})
    if row.status == 'reviewing' and row.claimed_by != admin_id:
        raise HTTPException(409, detail={"code": 50008, "message": "工单已被他人认领", "claimed_by": row.claimed_by, "claimed_at": row.claimed_at})
    if row.status in ['resolved','dismissed']:
        raise HTTPException(400, detail={"code": 50009, "message": "工单已结案"})
```

- [ ] **Step 1: 写 handlers**

- [ ] **Step 2: 在 router/__init__.py 注册**

```python
from .moderation_admin import router as moderation_admin_router
admin_router.include_router(moderation_admin_router)
```

- [ ] **Step 3: 启动 FastAPI 验证**

```bash
cd TopFans-activity-admin
uvicorn backend.main:app --reload
curl http://localhost:8000/api/admin/moderation/reports -H "Authorization: Bearer $ADMIN_TOKEN"
# 期望：返回分页列表
```

---

### Task 3.3: 写单元测试

**Files:**
- Create: `backend/handlers/test_moderation_admin.py`

**关键测试**（spec §7.3）：
- 列表/详情/认领/动作 happy path
- dismiss 4 路径分支覆盖
- 鉴权测试（无 token → 401）
- 50008 vs 50009 区分
- Fixture：`httpx.AsyncClient` + pytest；admin token 用现有 `make_test_token()`

- [ ] **Step 1: 写测试**

- [ ] **Step 2: 跑测试**

```bash
cd TopFans-activity-admin
pytest backend/handlers/test_moderation_admin.py -v
```

---

## 阶段 4：后台前端 Vue3

### Task 4.1: API 封装

**Files:**
- Create: `frontend/src/api/moderation.js`

**关键函数**：
```javascript
import request from '@/utils/request'

export function getReports(params) { return request({ url: '/api/admin/moderation/reports', method: 'get', params }) }
export function getReportDetail(id) { return request({ url: `/api/admin/moderation/reports/${id}`, method: 'get' }) }
export function claimReport(id) { return request({ url: `/api/admin/moderation/reports/${id}/claim`, method: 'post' }) }
export function releaseReport(id) { return request({ url: `/api/admin/moderation/reports/${id}/release`, method: 'post' }) }
export function executeAction(id, payload) { return request({ url: `/api/admin/moderation/reports/${id}/actions`, method: 'post', data: payload }) }
export function bulkDismissReports(ids, reason) { return request({ url: '/api/admin/moderation/reports/bulk-dismiss', method: 'post', data: { report_ids: ids, reason } }) }
export function forceReleaseReport(id, reason) { return request({ url: `/api/admin/moderation/reports/${id}/force-release`, method: 'post', data: { reason } }) }
// 同模式：feedback API + categories API
```

**注意**：复用 `utils/request.js` 的 axios 拦截器（已含 JWT 注入）。

---

### Task 4.2: 举报工单列表页

**Files:**
- Create: `frontend/src/views/moderation/ReportList.vue`

**关键 UI**（Element Plus）：
- 筛选栏：状态 select + 分类 select + 目标类型 select + 关键词 input + 搜索按钮
- el-table 列表：report_id / target_type / target_id / category_code / status (el-tag) / claimed_by / created_at
- 分页：el-pagination
- 行操作：详情按钮（跳转 detail 页）

---

### Task 4.3: 举报详情页 + 审核动作

**Files:**
- Create: `frontend/src/views/moderation/ReportDetail.vue`

**关键 UI**：
- 顶部信息卡片：report_id / status / target_snapshot (JSON 展示) / 举报人 / 分类 / 描述
- 证据图：el-image preview
- 流水时间线：el-timeline（moderation_actions 列表）
- 动作按钮组（按 status 显隐）：
  - `pending` / `auto_hidden`：认领
  - `reviewing`（本人认领）：下架/封禁/警告/驳回/释放
  - 任何状态：详情查看

**关键交互**：
- "认领"按钮 → `claimReport` → 成功后切换到 reviewing 模式，按钮组切换
- "执行动作" → 弹 el-dialog 输入 action/note/send_notification → `executeAction`
- 4 条 dismiss 路径在 UI 上对应不同选项（"驳回（不恢复）"/"驳回（恢复隐藏对象）" 等）

---

### Task 4.4: 反馈列表/详情/分类管理页面

**Files:**
- Create: `frontend/src/views/moderation/{FeedbackList,FeedbackDetail,ReportCategoryConfig,FeedbackCategoryConfig,Dashboard}.vue`

```

---

### Task 5.2: ReportModal 通用举报弹窗

**Files:**
- Create: `frontend/components/ReportModal.vue`

**关键实现**（uView 2.x）：
- props: `targetType: 'asset' | 'user_profile'`, `targetId: Number`, `targetName: String`
- 表单：u-form 包含分类 radio + 描述 textarea + u-upload (max 5) + 匿名 switch
- 提交：
  - 调用 `submitReportApi`
  - 双分支 toast：
    - `res.data.target_hidden === true` → `uni.showToast({ title: '已自动隐藏，等待审核', icon: 'none' })`
    - 否则 → `uni.showToast({ title: '举报已提交', icon: 'success' })`
- 错误码处理（50004/50011/50012 等）：用 u-toast 显示 message

---

### Task 7.1: 通知模板注册

**Files:**
- Modify: `backend/services/notificationService/model/notification.go` 或 `notification_repository.go`（按现有模板管理方式）

**6 个模板**（spec §8）：
- `report_auto_hidden_notice` — 被举报方"内容已被自动隐藏"
- `report_resolved` — 举报人"举报已处理"
- `report_takedown_notice` — 被举报方"内容已被下架"
- `report_ban_notice` — 被举报用户"账号已被封禁"
- `report_warn_notice` — 被举报用户"已被警告"
- `feedback_replied` — 反馈人"反馈已回复"

**模板字段**：`{reporter_nickname, target_type, target_id, action, reason, related_url}`

- [ ] **Step 1: 写 6 个模板到 notificationService**

- [ ] **Step 2: 在 moderationService `client/notification_client.go` 替换 v1.5 stub 为真实现**

---

### Task 7.2: Go 单元测试

**Files:**
- Create/Modify: `backend/services/moderationService/service/{report,feedback,auto_hide,concurrency}_test.go`

**关键测试覆盖**（spec §7.2）：
- `report_service_test.go`：防重复、自动隐藏触发、dismiss 4 路径、claimed_* 一致性
- `feedback_service_test.go`：状态机 + claimed_* 一致性
- `auto_hide_service_test.go`：Lua 脚本逻辑

**关键场景**（spec §7.4）：
- 提交举报 → 后台审核 → 状态变更 → 通知
- 自动隐藏：5 个独立用户举报 → 自动隐藏 + 状态表写入
- dismiss 4 路径覆盖
- 跨服务事务回滚：业务表软删除成功但 mts UPSERT 失败，验证整体回滚

**隔离策略**：testcontainers-go 启临时 PG 16 + Redis 7，业务表自动跑阶段 1.1 迁移，Redis key 加 `test:mod:report:*` 前缀。

---
