+# Alembic（数据库迁移）
+
+## 1. 前置
+
+- 在 `server/` 下准备 `.env.dev`（或系统环境变量），至少包含：
+  - `DATABASE_URL=mysql+aiomysql://...`
+
+> 注意：本仓库推荐使用 Python 虚拟环境（venv）。示例以 `server/.venv` 为准。
+
+---
+
+## 2. 安装依赖（一次性）
+
+在仓库根目录：
+
+```bash
+python3 -m venv server/.venv
+source server/.venv/bin/activate
+pip install -r server/requirements.txt
+```
+
+---
+
+## 3. 常用命令
+
+在 `server/` 目录运行：
+
+```bash
+source .venv/bin/activate
+alembic -c alembic.ini history
+alembic -c alembic.ini upgrade head
+```
+
+---
+
+## 4. 说明
+
+- 连接串由 `alembic/env.py` 从环境变量 `DATABASE_URL`（或 `app/core/config.py`）读取。
+- 初始迁移版本为：`0001_init_content_tables`（创建推荐系统最小内容表与画像表）。

+# Client User Identity｜客户端用户标识建立（用于 PUSH Token 绑定）｜Spec
+
+> 阶段：高层规范（spec）
+>
+> 目标：在**无账号体系或账号可选**的前提下，为客户端生成一个稳定的“客户端用户标识”（下称 `client_user_id`），用于与 APNs/FCM 的 Push Token 建立绑定关系，便于后端精准下发 PUSH，并支持 Token 变更/多设备/环境隔离等场景。
+
+---
+
+## 1. 背景与动机（摘要）
+
+Push Token（APNs device token / FCM registration token）会发生变化（重装、系统升级、重新授权、token rotate 等），且同一用户可能多设备。为了能稳定地“找到这个客户端实例/用户侧主体”并维护 Token 映射，需要一个**与 Token 解耦**、可持久化、不可推断的标识。
+
+---
+
+## 2. 目标（Goals）
+
+- **建立 `client_user_id`**：客户端可生成并持久化一个稳定标识，作为后端 Push Token 绑定的主键之一。
+- **Token 绑定可更新**：支持 Token 变更时“同一 `client_user_id` 重新上报即可更新”。
+- **多设备兼容**：同一个账号（若未来引入）可关联多个 `client_user_id`；一个 `client_user_id` 可存在多个 Token（例如同设备多渠道/多应用包形态）时需可扩展。
+- **环境隔离**：dev/prod、iOS/Android、bundle id / package name 维度隔离，避免串绑。
+- **隐私友好**：不使用可追踪的硬件标识（IMEI/IDFA/Android ID 等），不引入额外合规风险。
+
+---
+
+## 3. 非目标（Non-goals）
+
+- 不在本阶段引入完整账号体系、登录态、用户合并策略（如“同一人多设备合并为一个 user_id”）。
+- 不在本阶段强制接入设备证明（App Attest/Play Integrity）；仅在安全章节提出可选增强方向。
+- 不定义具体数据库表结构与迁移脚本（属于 plan 阶段细化）。
+
+---
+
+## 4. 术语与对象（Definitions）
+
+- **`client_user_id`**：客户端生成并持久化的随机标识，代表“一个客户端安装实例（或一段时间内的用户侧主体）”，用于 Push 绑定。
+- **`push_token`**：系统/厂商下发的推送 token（iOS/APNs，Android/FCM），可能变化。
+- **`account_id`（可选）**：若未来存在登录账号，则用于把多个 `client_user_id` 归属到同一账号。
+
+---
+
+## 5. 关键决策：使用 UUID 做 `client_user_id` 是否合适？
+
+结论：**合适**，推荐用**随机 UUID（UUID v4 为默认）**，并把它当作后端与客户端都不解析的**不透明字符串**。
+
+### 5.1 为什么 UUID 合适
+
+- **唯一性足够**：v4 基于随机数，碰撞概率极低，满足全局唯一需求。
+- **不可推断**：相较自增 ID，不易被枚举；相较设备硬件标识，更隐私友好。
+- **跨端易实现**：iOS/Android/JS 都可稳定生成与序列化（字符串）。
+
+### 5.2 需要明确的边界与注意事项
+
+- **UUID 不等于“真实用户”**：它更像“安装实例 ID”。用户重装/清数据后可能变化；这对 Push 绑定通常可接受（新装产生新 token 与新 id）。
+- **不要用设备硬件/系统可追踪 ID 替代**：避免隐私与合规风险，也避免系统限制导致的不稳定。
+- **安全边界**：如果后端完全信任客户端上报的 `client_user_id`，存在“伪造绑定”风险；应结合登录态或签名/证明（见第 9 节）降低滥用。
+
+### 5.3 UUID 版本建议
+
+- **默认**：UUID v4（实现最简单、兼容最好）。
+- **可选增强**：UUID v7（有时间有序性，利于日志/索引与写入局部性），但需要确保两端实现一致与依赖可控。
+
+---
+
+## 6. 客户端行为规范（Client Contract）
+
+### 6.1 生成与持久化
+
+- 首次启动（或首次需要注册 Push 时）：
+  - 若本地不存在 `client_user_id`：生成一个新的 UUID（字符串），写入持久化存储。
+  - 若已存在：直接复用。
+- 存储建议（不做强约束，但必须“尽量稳定”）：
+  - iOS：Keychain
+  - Android：Keystore 保护的加密存储/SharedPreferences（或等价方案）
+  - React Native/Expo：使用安全存储能力（例如 SecureStore/Keychain wrapper）
+
+### 6.2 Push Token 获取与上报时机
+
+- 在以下任一时机触发“注册/更新”：
+  - 用户同意 Push 权限后获得 token
+  - App 冷启动获取到 token（含 token 变更）
+  - 账号登录/登出（若存在账号）
+  - 环境切换（dev/prod）或应用更新（可选）
+
+---
+
+## 7. 后端接口契约（API Contract，摘要）
+
+> 具体路由/鉴权方式在 plan 阶段落地；此处先定义字段语义与幂等行为。
+
+### 7.1 注册/更新绑定
+
+- `POST /v1/push/register`
+- 请求体（最小集）：
+  - `client_user_id`: string（UUID 字符串）
+  - `platform`: `"ios" | "android"`
+  - `push_token`: string
+  - `app_id`: string（bundle id / package name，用于隔离）
+  - `env`: `"dev" | "prod"`
+  - （可选）`account_id`: string
+  - （可选）`device_meta`: `{ model, os_version, app_version, locale, timezone }`
+- 行为要求（幂等）：
+  - 以 `push_token + env + app_id` 维度做唯一性约束，避免重复记录。
+  - 若同一 `client_user_id` 上报了新 token：应更新/新增映射，旧 token 进入失效或保留历史（由实现决定，但必须可控）。
+
+### 7.2 解绑（可选但建议）
+
+- `POST /v1/push/unregister`
+- 请求体：
+  - `client_user_id`
+  - `platform`
+  - `push_token`（或让后端按 `client_user_id` 批量解绑，二选一）
+  - `app_id`
+  - `env`
+
+---
+
+## 8. 数据模型（逻辑约束）
+
+最小需要表达的关系：
+
+- 一个 `client_user_id` 可对应 0..N 个 `push_token`（考虑多端、多渠道、token rotate）。
+- 一个 `push_token` 在同一 `env + app_id` 下应只对应一个“当前归属”（避免重复推送）。
+- 若存在 `account_id`：
+  - 一个 `account_id` 可关联 0..N 个 `client_user_id`（多设备）。
+
+---
+
+## 9. 安全与滥用防护（高层约束）
+
+- **最小要求**：接口需具备基本鉴权与频率限制（例如基于设备指纹/匿名 session/应用侧签名的任一组合），避免被脚本批量绑定垃圾 token。
+- **若存在登录态**：推荐绑定写入需要登录态（或在登录后把 `client_user_id` 归属到 `account_id`），降低“抢绑”风险。
+- **可选增强（后续）**：接入 iOS App Attest / Android Play Integrity，或对注册请求做一次性挑战签名。
+
+---
+
+## 10. 边界场景与处理原则
+
+- **用户拒绝 Push 权限**：允许只有 `client_user_id`，不产生 token 绑定；后端不应报错。
+- **token 变化**：客户端重新调用 `register`，后端必须幂等更新，避免重复推送。
+- **重装/清数据**：`client_user_id` 变化可接受；若未来有 `account_id`，可在登录后重新建立关联。
+- **多环境**：dev/prod token 不可混用；必须以 `env + app_id` 隔离。
+
+---
+
+## 11. 验收标准（Acceptance Criteria）
+
+- 客户端能稳定生成并持久化 `client_user_id`（重复启动不变）。
+- 在 token 获取/变更后，调用注册接口可在后端建立（或更新）绑定关系，且接口幂等。
+- 同一 `push_token` 在同一 `env + app_id` 下不会产生多条“当前有效”绑定，避免重复推送。
+- 在用户拒绝 Push 权限、无 token 的情况下，不影响 App 正常使用与后续再次授权后的绑定。

+
+> 对应规范：`spec_kit/Personalized Reco/modules/content-repository/spec.md`
+>
+> 依赖对齐：
+>
+> - DB 设计：`spec_kit/Personalized Reco/modules/db-design/plan.md`
+> - 回退梯度与场景口径：`spec_kit/Personalized Reco/spec.md`（Fallback Ladder + 场景默认参数）
+
+---
+
+## 1. 目标与交付物
+
+### 1.1 目标
+
+- 为推荐引擎提供**与 ORM/SQL 解耦**的数据访问接口：候选召回与按 ID 批量获取。
+- 将 DB 内部存储形态（JSON、关联表、NULL 语义等）统一“规范化”为上层稳定的 `ContentProfile` 结构。
+- 在候选不足时支持按 `fallback_level (L0~L3)` 进行**可控降级**（降个性化/回退通用池/安全池），并且不产生 N+1 查询。
+
+### 1.2 交付物
+
+- `modules/content-repository/plan.md`：本技术计划（本文件）。
+- 代码实现（后续 tasks 阶段落地）建议位置：
+  - `server/app/features/personalized_reco/content_repository/`（或等价目录）
+  - 需要包含：
+    - 抽象接口 `ContentRepository`（Protocol 或 ABC）
+    - SQLAlchemy 实现 `SqlAlchemyContentRepository`
+    - `ContentProfile`（DTO/数据结构）与规范化工具函数
+- 单元测试与最小集成测试（后续 tasks 阶段落地）：
+  - risk_flags 映射与去重
+  - suitability 缺失兜底
+  - personalization_power 映射
+  - 查询不出现按 `content_id` 循环查 flags（避免 N+1）
+
+---
+
+## 2. 关键技术决策（V1）
+
+### 2.1 存储形态（来自 DB Design 的已对齐结论）
+
+- `content_id`：MySQL 自增主键（`int`）。
+- `context_suitability_json / need_suitability_json`：JSON 存储。
+- `risk_flags`：关联表 `content_risk_flags(content_id, flag)`（同一 content 下 `uniq_content_flag` 去重）。
+- `emotion_score`：`NULL` 表示 general。
+- `review_confidence`：DB 可为 `NULL`；读取层输出时按 `0.7` 兜底（对齐规则口径）。
+- `personalization_power`：DB 推荐存 `0/5/10`；读取层输出稳定为 `0.0/0.5/1.0`。
+
+### 2.2 职责边界（避免耦合）
+
+- `Content Repository` **不负责** Hard Filter/Soft Scoring/Rerank/Freqcap（这些由引擎编排与打分子模块完成）。
+- `Content Repository` **负责**：
+  - 按 `fallback_level` 对候选池做“降级约束”（例如限制 `personalization_power`、回退通用池/安全池）
+  - 输出稳定结构（JSON 解析、默认值兜底、旧 flag 映射）
+
+---
+
+## 3. 接口与数据结构（V1）
+
+### 3.1 接口定义（与 spec 对齐）
+
+- `fetch_candidates(scene, user_profile, fallback_level, limit, locale, exclude_content_ids=None) -> List[ContentProfile]`
+- `fetch_contents_by_ids(content_ids: List[int], locale) -> List[ContentProfile]`
+
+### 3.2 `ContentProfile`（输出契约的推荐形态）
+
+稳定字段（必须输出）：
+
+- `content_id: int`
+- `text: str`
+- `stage: "general" | "expecting" | "parenting" | "unknown"`
+- `emotion_score: float | None`（`None` 表示 general）
+- `context_suitability: Dict[str, float]`
+- `need_suitability: Dict[str, float]`
+- `personalization_power: float`（`0/0.5/1`）
+- `risk_flags: List[str]`
+
+可选字段（尽量输出）：
+
+- `author_id: str | None`
+- `template_id: str | None`
+- `review_confidence: float`（缺失/NULL 按 `0.7` 输出）
+
+---
+
+## 4. 读取层规范化（Normalization）
+
+### 4.1 text 选文案与多语言策略（不允许回退）
+
+数据来源（当前 DB/ORM 约定）：
+
+- `contents.text_en`：英文
+- `contents.text_tc`：繁体中文
+
+规则（**不允许语言回退**）：
+
+- `locale=en*`：仅允许返回存在 `text_en` 的内容；输出 `text = text_en`
+- `locale=tc/zh-TW/zh-HK`：仅允许返回存在 `text_tc` 的内容；输出 `text = text_tc`
+
+若内容缺少目标语言文本（例如 `locale=en*` 但 `text_en` 为空）：该内容视为不可用，必须在候选/按 ID 获取时过滤掉。
+
+### 4.1 suitability JSON 解析与缺失兜底
+
+固定 key 集合（对齐 DB Plan 的最小入库契约）：
+
+- `context_suitability`：`family/work/relationship/friends/health`
+- `need_suitability`：`emotional_support/parenting_pressure/self_worth/anxiety_relief/rest_balance`
+
+规则：
+
+- 若 DB 字段缺失/为 `NULL`/解析失败：**补齐为全 0.5**（以上所有 key 均为 `0.5`）。
+- 若 DB JSON 存在但缺少部分 key：对缺少 key 补 `0.5`，其余按原值。
+- 值域约束：期望值为 `0/0.5/1`；若出现其他值（例如字符串、越界浮点），按 `0.5` 兜底并记录告警日志（V1 可先打 debug，后续接入可观测模块）。
+
+### 4.2 `review_confidence` 兜底
+
+- DB `review_confidence` 为 `NULL` 或缺失：输出 `0.7`。
+
+### 4.3 `personalization_power` 映射
+
+若 DB 存 `0/5/10`：
+
+- `0 -> 0.0`
+- `5 -> 0.5`
+- `10 -> 1.0`
+
+若读到其他值：按 `0.0` 兜底并记录告警日志。
+
+### 4.4 risk_flags 旧→新映射与输出约束
+
+映射表（对齐 spec）：
+
+- `block_stage_unknown` → `unsafe_for_stage_unknown`
+- `block_stage_parenting` → `unsafe_for_stage_parenting`
+- `block_emotion_low` → `unsafe_for_emotion_low`
+- `block_health_sensitive` → `block_health_medical`（V1 保守硬拦截）
+
+输出约束：
+
+- 输出 `risk_flags` 必须去重。
+- 输出不得包含旧命名。
+- 输出建议稳定排序（便于测试与可观测）：按字典序排序或按严重等级排序（V1 可先字典序）。
+
+---
+
+## 5. 查询策略（V1）
+
+> 原则：DB 层先做“粗过滤”，应用层再做“精过滤/打分”。避免在 V1 过早依赖 JSON 路径查询索引。
+
+### 5.1 `fetch_contents_by_ids`（按 ID 批量获取）
+
+目标：
+
+- 输入任意 `content_id` 列表，返回无重复的 `ContentProfile` 列表。
+- 避免 N+1：不得按 `content_id` 循环查 `content_risk_flags`。
+- 返回顺序：必须与输入 `content_ids` 一致（对“缺记录/缺语言文本”的 id 采取跳过策略，见下）。
+
+缺记录/缺语言文本的处理（V1 约定）：
+
+- 若某个 `content_id` 在 DB 中不存在，或按 `locale` 规则无法产出 `text`：该 id 在返回列表中**跳过**（不返回占位对象）。
+
+推荐实现形态（两段式，避免 JOIN 导致重复行）：
+
+1. **批量拉主体与画像**（`contents` JOIN `content_profiles`），限制 `content_id IN (...)`。
+2. **批量拉 risk_flags**：`SELECT content_id, flag FROM content_risk_flags WHERE content_id IN (...)`，在应用层按 `content_id` 聚合为集合，再做旧→新映射与去重。
+
+备注：
+
+- 由于 `content_risk_flags` 是 1:N，直接三表 JOIN 容易导致行膨胀；两段式更便于组装与去重。
+
+### 5.2 `fetch_candidates`（候选召回，支持 L0~L3）
+
+输入：
+
+- `scene: feed | push | widget`
+- `user_profile`（允许字段缺失）
+- `fallback_level: 0|1|2|3`
+- `limit`
+- `exclude_content_ids`（可选）
+
+#### 5.2.1 fallback_level 约束（对齐大规范 Fallback Ladder）
+
+从 `spec_kit/Personalized Reco/spec.md` 对齐：
+
+- **L0**：正常召回配比（不在读取层实现复杂配比，读取层只保证候选池足够大且不过度放宽）
+- **L1**：放宽匹配 + 降个性化：限制 `personalization_power ≤ 0.5`
+- **L2**：回退通用池 + 进一步降个性化：限制 `personalization_power = 0`，且优先 `stage=general`
+- **L3**：兜底安全池：限制 `is_safe_pool = true`（安全池字段来自 DB Design）
+
+缺失字段的最小处理（对齐大规范 Candidate Generation 口径）：
+
+- 若 `user_profile` 缺失明显（need/context/emotion 任一缺失）：读取层按**至少 L1** 的约束执行（即使入参 fallback_level=0）。
+
+#### 5.2.2 stage 粗过滤策略（V1）
+
+读取层可做的最小粗过滤（不引入复杂业务判断）：
+
+- **L2/L3**：只取 `stage=general`（L3 额外 `is_safe_pool=true`）。
+- **L0/L1**：
+  - 优先取 `stage=用户匹配阶段` + `stage=general`
+  - 若无法从 `user_profile` 明确阶段，则仅取 `stage=general`（避免误推）
+
+> 说明：更细粒度的阶段/跨维度规则（例如 unknown+parenting_pressure 的禁推）由 Hard Filter 子模块实现；读取层仅做粗过滤以减少扫描与传输。
+
+#### 5.2.3 查询形态（避免 JOIN 行膨胀 + 保证 limit）
+
+推荐采用“两段式候选召回”：
+
+1. **先只查候选 ID 列表**（`contents` JOIN `content_profiles`），应用粗过滤（stage / personalization_power / is_safe_pool / exclude_content_ids），并增加 **locale 文本存在性过滤**（不允许语言回退），再用 `LIMIT limit * multiplier` 拉一批候选 ID（`multiplier` 例如 3~5，避免后续去重/过滤后不足）。
+2. **再用 `fetch_contents_by_ids` 批量补全字段**（主体+画像+risk_flags），最终在应用层去重并截断到 `limit`。
+
+排序（V1）：
+
+- 若没有更明确的排序字段：使用 `updated_at DESC` 或随机抽样（需谨慎，MySQL `ORDER BY RAND()` 在大表会慢）。
+- 推荐：V1 先用 `content_profiles.updated_at DESC` 或 `contents.created_at DESC`，后续由打分模块决定最终排序。
+
+---
+
+## 6. 性能与可观测（V1）
+
+### 6.1 性能约束
+
+- 单次调用不得出现按 `content_id` 循环查库（避免 N+1）。
+- `fetch_candidates` 必须在 DB 层支持 `limit`，并尽量通过粗过滤减少扫描。
+
+### 6.2 建议打点/日志（为 observability 子模块预留）
+
+在 Repository 层建议输出 debug 级日志（或埋点字段，供上层汇总）：
+
+- `scene`
+- `fallback_level`（入参）与 `effective_fallback_level`（考虑缺失字段自动至少 L1 后的实际约束级别）
+- `limit`、`exclude_content_ids_count`
+- `candidate_ids_size_raw`（第 1 段查到的候选 ID 数）
+- `candidate_size_returned`（最终返回数量）
+
+---
+
+## 7. 测试计划（V1）
+
+### 7.1 单元测试（纯函数）
+
+- risk_flags 映射：
+  - 输入包含旧 flag，输出只包含新命名
+  - 去重与稳定排序
+- suitability 兜底：
+  - DB 字段缺失/NULL/解析失败 → 全 0.5
+  - 部分 key 缺失 → 补齐 0.5
+- personalization_power 映射：
+  - 0/5/10 → 0.0/0.5/1.0
+  - 异常值 → 0.0 兜底
+- review_confidence：
+  - NULL/缺失 → 0.7
+
+### 7.2 最小集成测试（含数据库）
+
+- `fetch_contents_by_ids`：
+  - 输入多个 id 返回无重复
+  - flags 聚合正确（同一 content 多条 flag 行能聚合成 list）
+- 查询次数断言（避免 N+1）：
+  - `fetch_contents_by_ids`：固定 2 次查询（主体+画像一次，flags 一次）
+  - `fetch_candidates`：固定 3 次查询（候选 id 一次 + `fetch_contents_by_ids` 两次），或实现允许的常数级次数
+
+---
+
+## 8. 风险与后续演进
+
+### 8.1 已知风险
+
+- V1 不做 JSON 路径索引：候选量变大后，粗过滤不足可能导致候选池拉取过多、应用层过滤成本上升。
+- `ORDER BY RAND()` 的性能风险：候选大表下不可用，需要替代策略（时间窗口抽样/预生成候选池）。
+
+### 8.2 V1.1 优化方向（与 DB Plan 对齐）
+
+- 为常用 need/context key 增加生成列/函数索引（从 JSON_EXTRACT 提取到 TINYINT）以加速召回。
+- 为强规则风险（如 `block_health_medical`）增加派生布尔列或缓存表，减少 JOIN 成本。

+    - `locale=tc/zh-TW/zh-HK`：必须从 `contents.text_tc` 产出；若无 `text_tc`，则该 content 不可返回
+  - `stage`：`general | expecting | parenting | unknown`
+  - `emotion_score`：`float | None`（约定：`None` 表示 general）
+  - `context_suitability`：`Dict[str, float]`（见 4.1 的 key 集合；值为 `0/0.5/1`）
+  - `need_suitability`：`Dict[str, float]`（见 4.1 的 key 集合；值为 `0/0.5/1`）
+  - `personalization_power`：`float`（对上稳定口径为 `0/0.5/1`；若 DB 存 `0/5/10`，读取层需映射）
+  - `risk_flags`：`List[str]`（已做旧→新映射、去重；命名只允许 `unsafe_for_* / block_* / soft_*`）
+  - 可选：`author_id`、`template_id`、`review_confidence`
+
+### 2.3 数据存储形态（对齐 DB 设计）
+
+> 对齐：`spec_kit/Personalized Reco/modules/db-design/plan.md`
+
+- `contents`：提供 `content_id`、`text`、（可选）`author_id`、`template_id`
+- `content_profiles`：提供 `stage`、`emotion_score`、`context_suitability_json`、`need_suitability_json`、`personalization_power`（推荐存 `0/5/10`）、（可选）`review_confidence`
+- `content_risk_flags`：通过关联表提供风险标记集合（同一 content 下按 `uniq_content_flag(content_id, flag)` 去重）
+
+---
+
+## 3. 接口（建议）
+
+推荐模块对该子模块只依赖抽象接口（Python Protocol/ABC 均可）：
+
+- `fetch_candidates(scene, user_profile, fallback_level, limit, exclude_content_ids=None) -> List[ContentProfile]`
+- `fetch_contents_by_ids(content_ids: List[int]) -> List[ContentProfile]`
+
+---
+
+## 4. 关键规则与实现约束
+
+### 4.1 字段缺失与默认值
+
+- 若 `review_confidence` 缺失：输出时默认按 `0.7`（对齐 `句子文案打分规则` V1.2 约定）。
+- `context_suitability/need_suitability` 若缺失：**读取层必须补齐为“全 0.5 的通用可推”结构**（稳定输出，避免上层分支判断）。
+  - `context_suitability` 必须包含 5 个 key：`family/work/relationship/friends/health`
+  - `need_suitability` 必须包含 5 个 key：`emotional_support/parenting_pressure/self_worth/anxiety_relief/rest_balance`
+  - 补齐时上述 key 的默认值均为 `0.5`
+- `personalization_power`：若 DB 采用 `0/5/10` 存储，读取层必须映射为 `0.0/0.5/1.0` 对上输出。
+
+### 4.2 risk_flags 兼容映射（若存在历史旧数据）
+
+对齐 `句子文案打分规则` 的旧→新映射：
+
+- `block_stage_unknown` → `unsafe_for_stage_unknown`
+- `block_stage_parenting` → `unsafe_for_stage_parenting`
+- `block_emotion_low` → `unsafe_for_emotion_low`
+- `block_health_sensitive` → `block_health_medical`（读取层默认采用更保守的硬拦截映射；除非未来引入可判定的细分字段再放宽为 `soft_health_sensitive`）
+
+输出约束：
+
+- 输出的 flags 必须已去重，且不得包含任何旧命名。
+
+### 4.3 性能约束
+
+- 不得产生 N+1 查询：候选与字段必须一次或少量批量查询获取。
+- `fetch_candidates` 必须支持 limit，并在 DB 层尽量过滤（减少应用层扫描）。
+- `fetch_contents_by_ids` / `fetch_candidates` 推荐查询形态：
+  - `contents` JOIN `content_profiles`，再 LEFT JOIN `content_risk_flags`（或先批量取 profiles，再批量取 flags 并在应用层聚合），避免按 `content_id` 循环查 flags。
+
+---
+
+## 5. 验收标准（可验证）
+
+- `fetch_contents_by_ids`：
+  - 输入任意 `content_id` 列表，返回包含完整字段的 `ContentProfile` 列表（无重复、可缺省字段按约定兜底）。
+- `fetch_candidates`：
+  - 在不同 `scene` 与 `fallback_level` 下能返回候选（即便画像缺失也不报错）。
+  - risk_flags 映射正确：输出的 flag 名称集合只包含新命名（`unsafe_for_* / block_* / soft_*`）。
+- 性能：
+  - 单次调用不出现按 content_id 循环查库的行为（可通过日志/测试断言查询次数）。

+## 0. 任务标记规则
+
+- 用勾选框标记执行状态：
+  - `[ ]` 未开始
+  - `[x]` 已完成
+- 每个任务都要求可独立验收（有明确产出/可运行的检查方式）。
+
+---
+
+## 1. 文档对齐（先把口径写死，避免实现漂移）
+
+- [x] 1.1 更新 `modules/content-repository/spec.md`，加入 locale 相关契约
+  - **变更点**：
+    - 在输入中新增 `locale`（例如 `en`/`en-US`/`tc`/`zh-TW`/`zh-HK`），声明由客户端请求携带并透传至 repository
+    - 在输出字段 `text` 补充语言选择规则：
+      - `locale=en*`：必须从 `text_en` 产出；若缺失则该内容不可返回（过滤）
+      - `locale=zh-TW|zh-HK`：必须从 `text_tc` 产出；若缺失则该内容不可返回（过滤）
+      - 说明：当前仅支持 EN/TC（不做繁转简）；若未来新增 `zh-CN` 再单独设计转换策略
+    - 明确：`fetch_contents_by_ids` **返回顺序与入参一致**
+  - **验收**：`spec.md` 中输入/输出与接口签名不再缺少 locale，且 `text` 的来源与“不允许语言回退”规则清晰。
+
+- [x] 1.2 更新 `modules/content-repository/plan.md`，补齐 locale 选文与“繁转简”技术方案
+  - **变更点**：
+    - 在“读取层规范化（Normalization）”新增 `text` 规范化章节：语言选择 + 简中转换
+    - 说明：当前仅支持 EN/TC（不做繁转简）；若未来新增 `zh-CN` 再单独设计转换策略
+    - 明确策略：**不允许语言回退**；缺少目标语言文本的内容视为不可用，必须在候选/按 ID 获取时过滤掉
+  - **验收**：`plan.md` 有明确依赖与落地策略（含依赖包/转换时机/兜底策略），不留二义性。
+
+---
+
+## 2. 目录与骨架（与推荐子模块同级）
+
+- [x] 2.1 新建目录 `server/app/features/personalized_reco/content_repository/`
+  - **包含**：
+    - `__init__.py`
+    - `types.py`（DTO：`ContentProfile`、locale 类型等）
+    - `interface.py`（`ContentRepository` Protocol/ABC）
+    - `normalization.py`（解析与兜底：suitability、risk_flags、power、text）
+    - `sqlalchemy_repo.py`（SQLAlchemy 实现）
+  - **验收**：可被 `app.features.personalized_reco.content_repository.*` 正常 import。
+
+- [ ] 2.2 依赖补齐（如采用 OpenCC）
+  - **说明**：当前仅支持 EN/TC，此任务可跳过；若未来新增 `zh-CN` 并需要繁转简，再引入 OpenCC。
+
+---
+
+## 3. 数据结构与接口（面向引擎注入）
+
+- [x] 3.1 定义 `ContentProfile` DTO（稳定字段契约）
+  - **字段**：对齐 `modules/content-repository/spec.md`，并补齐 `review_confidence` 输出兜底为 `0.7`
+  - **注意**：`text` 为最终对外输出文本（已按 locale 选择/转换）
+  - **验收**：DTO 字段齐全；类型清晰；不暴露 ORM 模型。
+
+- [x] 3.2 定义 `ContentRepository` 接口（含 locale）
+  - **建议签名**（示例，最终以 spec 为准）：
+    - `fetch_candidates(scene, user_profile, fallback_level, limit, locale, exclude_content_ids=None) -> List[ContentProfile]`
+    - `fetch_contents_by_ids(content_ids, locale) -> List[ContentProfile]`
+  - **验收**：推荐引擎可以仅依赖该接口，不依赖 SQLAlchemy/FastAPI Depends。
+
+---
+
+## 4. 规范化工具函数（可单测）
+
+- [x] 4.1 suitability 解析与兜底
+  - **规则**：
+    - 缺失/NULL/解析失败 → 全 0.5（固定 key 集合）
+    - 部分 key 缺失 → 对缺失 key 补 0.5
+    - 非法值 → 兜底 0.5
+  - **验收**：单元测试覆盖缺失/部分缺失/非法值。
+
+- [x] 4.2 risk_flags 映射、去重与排序
+  - **规则**：旧→新映射对齐 spec；去重；稳定排序（例如字典序）
+  - **验收**：单元测试断言输出不含旧命名且顺序稳定。
+
+- [x] 4.3 personalization_power 映射
+  - **规则**：`0/5/10 -> 0.0/0.5/1.0`；非法值 -> 0.0
+  - **验收**：单元测试覆盖正常/异常值。
+
+- [x] 4.4 text 选择与简中转换
+  - **输入**：`text_en`、`text_tc`、`locale`
+  - **规则**：按 1.1/1.2 写死的策略执行（当前仅支持 EN/TC，不做繁转简）
+  - **验收**：单元测试覆盖：
+    - `en` 取英文
+    - `zh-TW` 取繁中
+    - 缺失目标语言文本时的行为：返回“不可用”（例如返回空字符串 + 上层过滤，或直接返回 `None` 由调用方过滤；实现中必须一致）
+
+---
+
+## 5. SQLAlchemy 实现（无 N+1、顺序可控）
+
+> 说明：当前 DB 模型为：
+>
+> - `contents`：`text_en` / `text_tc` / `author_id` / `template_id`
+> - `content_profiles`：JSON、power、stage、is_safe_pool、review_confidence
+> - `content_risk_flags`：关联表（1:N）
+
+- [x] 5.1 实现 `fetch_contents_by_ids(content_ids, locale)`
+  - **实现要点**：
+    - 输入去重，但输出必须按原始输入顺序重排（并忽略不存在的 id 或明确行为：不存在则跳过）
+    - 两段式查询避免行膨胀：
+      1) `contents` JOIN `content_profiles` 批量取主体与画像
+      2) `content_risk_flags` 批量取 flags，再按 `content_id` 聚合
+    - 组装 DTO 时执行 normalization（含 text locale 规则）
+  - **验收**：
+    - 返回顺序与输入一致
+    - 缺失目标语言文本的 content_id 不返回（跳过，不做语言回退）
+    - 不产生按 id 循环查 flags 的查询（查询次数为常数级）
+
+- [x] 5.2 实现 `fetch_candidates(scene, user_profile, fallback_level, limit, locale, exclude_content_ids)`
+  - **实现要点**：
+    - 计算 `effective_fallback_level`：
+      - 若画像 need/context/emotion 任一缺失，则 `effective_fallback_level = max(fallback_level, 1)`
+    - DB 粗过滤对齐 plan：
+      - L1：`personalization_power <= 5`
+      - L2：`personalization_power = 0` 且 `stage = general`
+      - L3：`is_safe_pool = true` 且 `stage = general` 且 `personalization_power = 0`（如需更严格可在此明确）
+    - 排序（V1）：按 `content_profiles.updated_at DESC` 或 `contents.updated_at DESC`（择一写死并记录）
+    - 两段式候选：
+      1) 先查候选 id（`LIMIT limit * multiplier`）
+      2) 调用 `fetch_contents_by_ids` 补全字段
+    - locale 文本存在性过滤：
+      - `locale=en*`：`contents.text_en IS NOT NULL`
+      - `locale=zh-*`：`contents.text_tc IS NOT NULL`
+    - 输出顺序：
+      - 返回顺序按候选 id 列表顺序（用于后续引擎打分/重排）；最终截断至 `limit`
+  - **验收**：
+    - 在不同 `effective_fallback_level` 下能返回候选
+    - 不返回缺少目标语言文本的内容（不做语言回退）
+    - 查询次数为常数级（不随 `limit` 线性增长）
+
+---
+
+## 6. DB 集成测试（dev MySQL）
+
+- [x] 6.1 建立测试目录与 pytest 配置
+  - **目标**：在 `server/` 内新增 `tests/`（或 `app/**/__tests__/`，但建议统一为 `server/tests/`）
+  - **内容**：
+    - `server/tests/conftest.py`：提供 AsyncEngine/AsyncSession、清库策略、query count 统计工具
+    - 测试运行约定：通过 `DATABASE_URL` 指向 dev 测试库（建议单独库名，例如 `mindfulness_dev_test`）
+  - **验收**：`pytest` 可在 `server/` 下运行并发现测试。
+
+- [x] 6.2 测试库 schema 初始化（用 Alembic）
+  - **策略**（二选一写死）：
+    - A：测试启动时 `alembic upgrade head`（确保 schema 最新）
+    - B：在 CI/本地提前准备库，仅在测试中清表
+  - **验收**：测试运行前 schema 可用，且不会污染开发主库数据（推荐使用独立 test 库）。
+
+- [x] 6.3 集成测试用例：`fetch_contents_by_ids`
+  - **准备数据**：插入最小内容 2~3 条（覆盖 text_en/text_tc 缺失组合）、profiles、flags（含旧 flag）
+  - **断言**：
+    - 返回顺序与输入一致
+    - `en` 不返回 `text_en` 缺失的内容（不回退 `text_tc`）
+    - risk_flags 映射后不含旧命名
+    - `review_confidence` NULL → 0.7
+  - **验收**：测试稳定通过。
+
+- [x] 6.4 集成测试用例：`fetch_candidates`
+  - **准备数据**：覆盖 `personalization_power` 0/5/10、`is_safe_pool` true/false、不同 stage
+  - **断言**：
+    - L1/L2/L3 粗过滤生效
+    - `exclude_content_ids` 生效
+    - 查询次数为常数级（用 before_cursor_execute 计数）
+  - **验收**：测试稳定通过。
+
+---
+
+## 7. 最终自检清单（合入前）
+
+- [x] 7.1 文档一致性检查
+  - `spec.md` / `plan.md` / 实现接口签名三者一致（尤其是 `locale` 与 `text` 输出规则）
+
+- [x] 7.2 性能检查（最小）
+  - `fetch_contents_by_ids` / `fetch_candidates` 查询次数断言通过（无 N+1）
+
+- [x] 7.3 回归检查
+  - 不影响现有 `user_profile_scoring` 模块与迁移脚本（仅新增模块与测试）

+
+## 1. 目标与交付物
+
+### 1.1 目标
+
+- 在“库为空”的前提下，落地推荐系统最小可用的数据模型。
+- 保证后续推荐查询可实现：按画像条件召回、按 ID 批量查、按风险标记过滤、支持安全池兜底。
+
+### 1.2 交付物
+
+- `server/alembic/`：Alembic 初始化目录、`alembic.ini`（或等价配置）、迁移脚本。
+- SQLAlchemy ORM 模型（建议放 `server/app/db/models/`）。
+- 初始迁移：创建 `contents`、`content_profiles`、`content_risk_flags`（以及必要索引）。
+
+---
+
+## 2. 技术决策（V1）
+
+### 2.1 表设计原则
+
+- **分离主体与画像**：`contents` 存文本与来源字段；`content_profiles` 存画像字段（便于未来画像重算/回填）。
+- **JSON 存 suitability**：`context_suitability`、`need_suitability` 用 JSON，保持结构与规则文档一致。
+- **risk_flags 关联表**：用 `content_risk_flags(content_id, flag)`，便于：
+  - 快速 Hard Filter（`block_health_medical` 等）
+  - 索引与统计（按 flag 计数）
+  - 兼容旧 flag 映射（在写入/读取层）
+- **emotion_score 的 general 表示**：用 `NULL` 表示 general（与规则文档“可为 general”语义等价）。
+- **personalization_power**：存为 `TINYINT`（0/5/10）或 `DECIMAL(2,1)`（0/0.5/1）。本计划推荐 `TINYINT`（更易索引/更省空间），应用层做映射：
+  - 0 → 0.0
+  - 5 → 0.5
+  - 10 → 1.0
+
+### 2.2 字符集与排序规则
+
+- 数据库与表：`utf8mb4`
+- collation：建议 `utf8mb4_0900_ai_ci`（MySQL 8 默认更常见；若环境不同以实际为准，但必须 utf8mb4）
+
+---
+
+## 3. 表结构（V1 方案）
+
+> 以下为“建议 schema”。实际字段名可调整，但语义必须严格对齐 `句子文案打分规则`。
+
+### 3.1 `contents`（文案主体）
+
+- `content_id` BIGINT UNSIGNED PK AUTO_INCREMENT
+- `text` TEXT NOT NULL
+- `author_id` VARCHAR(64) NULL
+- `template_id` VARCHAR(64) NULL
+- `created_at` DATETIME NOT NULL
+- `updated_at` DATETIME NOT NULL
+
+索引建议：
+
+- `idx_contents_author_id(author_id)`
+- `idx_contents_template_id(template_id)`
+
+### 3.2 `content_profiles`（内容画像）
+
+- `content_id` BIGINT UNSIGNED PK（FK → contents.content_id，ON DELETE CASCADE）
+- `stage` ENUM('general','expecting','parenting','unknown') NOT NULL DEFAULT 'general'
+- `emotion_score` DECIMAL(3,2) NULL
+  - 约定：NULL 表示 general
+- `context_suitability_json` JSON NOT NULL
+- `need_suitability_json` JSON NOT NULL
+- `personalization_power` TINYINT UNSIGNED NOT NULL DEFAULT 0
+  - 约定：只允许 0/5/10
+- `review_confidence` DECIMAL(3,2) NULL
+  - 约定：NULL 由推荐模块按 0.7 兜底（对齐规则文档）
+- `is_safe_pool` BOOLEAN NOT NULL DEFAULT FALSE
+- `updated_at` DATETIME NOT NULL
+
+索引建议：
+
+- `idx_profiles_stage(stage)`
+- `idx_profiles_personalization_power(personalization_power)`
+- `idx_profiles_is_safe_pool(is_safe_pool)`
+
+> 说明：suitability 放 JSON 后，V1 可以先不做 JSON 路径索引；当候选量上来后再加“生成列/函数索引”做加速（见 6.2）。
+
+### 3.3 `content_risk_flags`（风险标记，关联表）
+
+- `id` BIGINT UNSIGNED PK AUTO_INCREMENT
+- `content_id` BIGINT UNSIGNED NOT NULL（FK → contents.content_id，ON DELETE CASCADE）
+- `flag` VARCHAR(64) NOT NULL
+- `created_at` DATETIME NOT NULL
+
+约束与索引：
+
+- UNIQUE：`uniq_content_flag(content_id, flag)`（同一 content 不重复插同 flag）
+- 索引：`idx_flag(flag)`（用于 Hard Filter 与统计）
+- 索引：`idx_content_id(content_id)`（用于按内容批量取 flags）
+
+命名约束（应用层强制，DB 可选）：
+
+- flag 必须以 `unsafe_for_` / `block_` / `soft_` 开头（严格对齐规则文档）
+
+---
+
+## 4. Alembic 迁移落地步骤
+
+### 4.1 依赖与目录
+
+- 后端依赖：`alembic`（加入 `server/requirements.txt`，版本随项目统一管理）
+- 目录：`server/alembic/`（包含 `env.py`、`versions/`）
+- 连接串：复用现有 `DATABASE_URL`（`mysql+aiomysql://...`）
+
+### 4.2 初始化与生成迁移（一次性）
+
+- `alembic init alembic`（在 `server/` 下）
+- 配置 `env.py`：
+  - 从 `app/core/config.py` 读取 `DATABASE_URL`
+  - 引入 ORM Base 与 models，启用 autogenerate
+- 创建初始迁移：
+  - `alembic revision --autogenerate -m "init content tables"`
+  - `alembic upgrade head`
+
+### 4.3 dev/pro 一致性
+
+- 迁移脚本保持同一套；通过不同环境的 `DATABASE_URL` 指向 `mindfulness_dev` 或 `mindfulness`。
+
+---
+
+## 5. 入库流程（写入契约）
+
+### 5.1 一条文案最小入库数据
+
+必须字段（V1 最小可用）：
+
+- `text`
+- `content_profiles.stage`
+- `content_profiles.emotion_score`（可为 NULL 表示 general）
+- `content_profiles.context_suitability_json`（必须包含 5 个 key：family/work/relationship/friends/health，值为 0/0.5/1）
+- `content_profiles.need_suitability_json`（必须包含 5 个 key：emotional_support/parenting_pressure/self_worth/anxiety_relief/rest_balance，值为 0/0.5/1）
+- `content_profiles.personalization_power`（0/5/10）
+- `content_risk_flags`（可为空集合，但若存在必须按命名规范）
+
+强烈建议字段：
+
+- `author_id`、`template_id`
+- `review_confidence`
+- `is_safe_pool`（若要参与 L3 安全池）
+
+### 5.2 写入策略
+
+- 创建文案时：
+  - 先写 `contents` 得到 `content_id`（自增）
+  - 再写 `content_profiles`（同 content_id）
+  - 再批量写 `content_risk_flags`
+- 文案微调时（content_id 不变）：
+  - 更新 `contents.text` 与 `updated_at`
+  - 同步更新 `content_profiles`（若画像变更）
+  - risk_flags 做“全量覆盖”或“差量更新”（plan 实现阶段定）
+
+---
+
+## 6. 查询与性能规划
+
+### 6.1 V1 查询策略（先可用）
+
+- 候选召回：
+  - 先按 `stage`、`personalization_power`、`is_safe_pool` 等可索引字段进行粗过滤
+  - 再在应用层结合 suitability JSON 与 risk_flags 做精过滤/打分
+- Hard Filter：
+  - 通过 `content_risk_flags` join 或子查询排除指定 flags（如 `block_health_medical`）
+- 批量查：
+  - `content_id IN (...)` join `content_profiles` + left join `content_risk_flags`
+
+### 6.2 V1.1 性能增强（候选量上来后再做）
+
+当候选池变大、应用层过滤成本上升时，优先做两类增强：
+
+- **生成列/函数索引**：为常用召回维度（例如 need/context 的某些 key）创建 generated columns（从 JSON_EXTRACT 取值并映射到 TINYINT），再加索引。
+- **风险 flag 位图/派生列**：对 `block_health_medical` 等强规则增加派生布尔列（或维护冗余表），降低 join 成本。
+
+---
+
+## 7. 测试与验收（DB 子模块）
+
+### 7.1 迁移验收
+
+- 在全新库执行 `alembic upgrade head` 成功。
+- 执行 `downgrade`（若实现）可回滚（至少在开发环境可用）。
+
+### 7.2 数据契约验收
+
+插入一条最小文案记录后，能够查询并组装出推荐模块所需的 `ContentProfile` 字段集合：
+
+- `content_id/text/stage/emotion_score/context_suitability/need_suitability/personalization_power/risk_flags`
+
+### 7.3 规则口径验收（写入侧）
+
+- 写入 `risk_flags` 时，若出现旧 flag（如 `block_stage_unknown`）：
+  - 写入层需在入库前映射为新命名（或拒绝写入并提示）
+  - 推荐侧读取层不得再出现旧 flag 名称
+
+---
+
+## 8. 与其他子模块的接口约定
+
+- `Content Repository` 只依赖本模块提供的表与字段语义，不依赖具体迁移实现细节。
+- 推荐引擎/打分模块对 `review_confidence` 的缺省值假设（0.7）在 DB 缺失时依然成立。

+在当前“数据库尚未设计且为空”的前提下，为个性化推荐提供最小可用的数据存储与索引能力：
+
+- 存储文案及其内容画像（Content Profile，Cᵢ）。
+- 能按画像条件进行候选召回（need/context/stage/general、personalization_power、risk_flags 等）。
+- 能按 `content_id` 批量查询（补全候选、去重/重排时取字段）。
+- 为后续标注/审核/置信度补齐留出扩展空间。
+
+> 规则口径：字段语义必须严格对齐 `设计说明文档/句子文案打分規則.md`。
+
+---
+
+## 2. 输入 / 输出定义
+
+### 2.1 输入
+
+- 内容侧提供的文案与画像数据（可由运营导入、AI Reviewer 产出、人审修正等方式写入）。
+- 推荐模块对数据访问的需求（召回过滤字段、排序字段、频控字段）。
+
+### 2.2 输出
+
+- 一套 MySQL 表结构（或视图）满足 `ContentProfile` 字段契约：
+  - `content_id`（稳定主键）
+  - `text`
+  - `stage`（`general/expecting/parenting/unknown`）
+  - `emotion_score`（0~1 或 `general` 的等价表示）
+  - `context_suitability`（每个 context 的 {0,0.5,1}）
+  - `need_suitability`（每个 need 的 {0,0.5,1}）
+  - `personalization_power`（0/0.5/1）
+  - `risk_flags`（命名以 `unsafe_for_* / block_* / soft_*` 为准）
+  - 可选：`author_id`、`template_id`、`review_confidence`
+- Alembic 迁移脚本：`alembic revision --autogenerate` / `alembic upgrade head` 可创建上述表。
+- 推荐查询需要的索引（至少支持按场景召回与按 ID 批量查）。
+
+---
+
+## 3. 建议表结构（V1，允许后续调整）
+
+> 说明：本子模块不强制具体表名；但需保证字段语义与索引可用。以下给出一个推荐落地方案，便于后续 plan 直接实现。
+
+### 3.1 `contents`（文案主体）
+
+- `content_id`（PK）
+- `text`
+- `author_id`（可空）
+- `template_id`（可空）
+- `created_at` / `updated_at`
+
+### 3.2 `content_profiles`（内容画像）
+
+- `content_id`（PK/FK → contents）
+- `stage`（枚举：general/expecting/parenting/unknown）
+- `emotion_score`（可为 NULL 表示 general，或用额外字段 `emotion_is_general` 表示）
+- `context_suitability_json`（JSON：每个 context -> 0/0.5/1）
+- `need_suitability_json`（JSON：每个 need -> 0/0.5/1）
+- `personalization_power`（DECIMAL(2,1) 或 TINYINT 映射到 0/0.5/1）
+- `risk_flags_json`（JSON 数组：字符串集合）
+- `review_confidence`（DECIMAL(3,2)，缺省可按 0.7 处理，由推荐模块兜底）
+- `updated_at`
+
+### 3.3 “通用安全池”支持（L3 兜底）
+
+至少提供一种方式能拉到安全池内容：
+
+- 方式 A：`content_profiles` 增加 `is_safe_pool`（boolean）
+- 方式 B：单独 `safe_pool_contents`（content_id 列表）
+
+---
+
+## 4. 索引与查询能力（V1 必需）
+
+- **按 ID 批量查**：`content_id in (...)`
+- **按 stage / personalization_power 过滤**：支持候选召回与回退梯度
+- **按 risk_flags 过滤**：
+  - 推荐做法：将 `risk_flags_json` 冗余为可索引的派生列/位图/多表行（plan 阶段定实现）
+  - V1 最小可用：允许先在应用层过滤（但需控制候选量，避免全表扫）
+
+---
+
+## 5. 验收标准（可验证）
+
+- **迁移可运行**：全新 MySQL 库上执行 `alembic upgrade head` 可成功创建表结构。
+- **字段契约可满足**：能从 DB 读出 `ContentProfile` 需要的字段（至少 content_id/text/stage/emotion_score/context_suitability/need_suitability/personalization_power/risk_flags）。
+- **基本查询可用**：
+  - 能按 `content_id` 批量拉取内容画像
+  - 能按 `stage/general` 与 `personalization_power` 条件召回候选（用于 L0~L3）
+- **安全池可用**：能稳定拉取 L3 兜底候选集（不依赖用户画像）。

+# DB Design & Migrations（数据库设计与迁移）｜Tasks
+
+> 对应计划：`spec_kit/Personalized Reco/modules/db-design/plan.md`
+>
+> 目标：在“库为空”的前提下，落地推荐系统最小可用数据模型 + Alembic 迁移，并通过最小查询/契约验收。
+
+---
+
+## 0. 任务状态约定
+
+- `[ ]`：未开始
+- `[~]`：进行中
+- `[x]`：已完成
+- `[-]`：已取消/不做（需写明原因）
+
+---
+
+## 1. 环境与依赖准备
+
+- [ ] **确认 MySQL 版本与字符集支持**
+  - 验收：MySQL 版本为 8.x；库/表可用 `utf8mb4`（建议 `utf8mb4_0900_ai_ci`）。
+- [x] **后端依赖补齐 Alembic**
+  - 说明：`server/requirements.txt` 已包含 `alembic>=1.13`
+  - 验收：在 `server/.venv` 中可成功 `import alembic`。
+
+---
+
+## 2. ORM 模型落地（推荐最小集合）
+
+- [x] **创建 ORM 模型目录**
+  - 目标路径：`server/app/db/models/`
+  - 验收：目录存在，且可被 Python 正常 import。
+- [x] **实现 `contents` 模型**
+  - 字段：`content_id(PK, 自增)`、`text_en?`、`text_tc?`、`author_id?`、`template_id?`、`created_at`、`updated_at`
+  - 索引：`author_id`、`template_id`
+  - 验收：Alembic autogenerate 能识别表结构。
+- [x] **实现 `content_profiles` 模型**
+  - 字段：`content_id(PK/FK)`、`stage(enum)`、`emotion_score(NULL=general)`、`context_suitability_json(JSON)`、`need_suitability_json(JSON)`、`personalization_power(0/5/10)`、`review_confidence?`、`is_safe_pool`、`updated_at`
+  - 索引：`stage`、`personalization_power`、`is_safe_pool`
+  - 验收：Alembic autogenerate 能识别表结构；`content_id` 具备外键与级联删除。
+- [x] **实现 `content_risk_flags` 模型（关联表）**
+  - 字段：`id(PK)`、`content_id(FK)`、`flag`、`created_at`
+  - 约束：`UNIQUE(content_id, flag)`
+  - 索引：`flag`、`content_id`
+  - 验收：Alembic autogenerate 能识别唯一约束与索引。
+
+---
+
+## 3. Alembic 初始化与迁移生成
+
+- [x] **初始化 Alembic 目录**
+  - 目标位置：`server/alembic/`（含 `versions/`、`env.py`）
+  - 验收：在 `server/` 下可运行 `alembic -h` 且能读取配置。
+- [x] **配置 Alembic 连接串来源**
+  - 要求：复用现有 `DATABASE_URL`（对齐 `server/app/core/config.py`）
+  - 验收：`alembic` 命令可加载 `env.py` 并读取 `DATABASE_URL`（未连 DB 验收留到第 4 章）。
+- [x] **配置 `env.py` 支持 autogenerate**
+  - 要求：引入 ORM `Base` 与 models（确保 metadata 完整）
+  - 验收：Alembic 能识别 `target_metadata`；且已提供初始迁移版本文件。
+- [ ] **生成并执行初始迁移**
+  - 命令：`alembic upgrade head`
+  - 验收：数据库中出现 `contents`、`content_profiles`、`content_risk_flags` 与 Alembic 版本表。
+
+---
+
+## 4. 数据契约验收（最小入库与查询）
+
+- [ ] **准备一条最小文案数据（人工插入或脚本）**
+  - 必须字段（对齐 plan）：`text`、`stage`、`emotion_score(可 NULL)`、`context_suitability_json(5 keys)`、`need_suitability_json(5 keys)`、`personalization_power(0/5/10)`、`risk_flags(可空)`
+  - 验收：可插入成功，不违反约束。
+- [ ] **验证按 `content_id` 批量查询可用**
+  - 目标：能 join 组装出 `ContentProfile` 所需字段集合（含 risk_flags 列表）
+  - 验收：至少验证字段：`content_id/text/stage/emotion_score/context_suitability/need_suitability/personalization_power/risk_flags`。
+- [ ] **验证 Hard Filter 关键 flag 可过滤**
+  - 插入：至少一条带 `block_health_medical` 的记录
+  - 验收：通过 `content_risk_flags` 可在 SQL 层排除该内容（后续供推荐候选召回使用）。
+- [ ] **验证安全池（L3）可用**
+  - 插入：至少一条 `is_safe_pool=true`
+  - 验收：可单独查询出安全池候选集（不依赖画像条件）。
+
+---
+
+## 5. 规则口径验收（risk_flags 严格对齐）
+
+- [ ] **建立 risk_flags 白名单/校验策略（写入侧或读取侧）**
+  - 要求：flag 命名必须以 `unsafe_for_` / `block_` / `soft_` 开头（对齐 `句子文案打分规则`）
+  - 验收：插入非法前缀时被拒绝或被修正（选择其一，并写清策略）。
+- [ ] **旧 flag 兼容映射验收（若存在历史数据导入）**
+  - 覆盖：`block_stage_unknown`→`unsafe_for_stage_unknown` 等（详见 plan）
+  - 验收：系统对外（读出/下游）不再出现旧 flag 名称。
+
+---
+
+## 6. 文档与交接
+
+- [ ] **补齐本子模块 README/说明（可选，但建议）**
+  - 内容：如何初始化 DB、如何跑迁移、如何插入一条最小文案数据、如何验证查询。
+  - 验收：新同学按文档能在 30 分钟内跑通迁移 + 插入 + 查询。
