+# 内容领域 V2 与学习访问投影
+
+状态：Accepted（破坏式重做，开发期）
+日期：2026-08-05
+
+## 决策
+
+题目是可复用资产，不再通过题库、地区、章节或知识点字段确定唯一归属。题库仅是编辑文件夹；题集是策划集合。题目通过 `QuestionPlacement` 放入一个大纲节点，并用受限 DNF 规则声明适用目标；发布器把事实编译为不可变 Release、Audience Segment 和候选行。学生请求只读取编译访问快照与候选投影，不在线遍历租户、套餐、地区、班级、老师和作业关系链。
+
+所有业务使用同一套可配置目标维度。新增考试业务时创建维度、目标 Profile、业务策略、大纲和产品 Manifest，不增加业务枚举或在刷题代码中加入分支。
+
+## 所有权和版本边界
+
+- `QuestionAsset.TenantId` 是资产所有者。平台公共内容使用平台内容所有者；租户私题只能由相同租户搜索、放置和发布。
+- `QuestionRevision` 创建后不可修改。完整交付指纹包含题型、题干、选项、答案、子题和代码内容；Unicode 和空白规范化不会忽略可见字符大小写。
+- 模糊相似仅由 `pg_trgm` 产生人工复核候选，不自动合并。
+- Profile、业务目标策略、大纲、试卷规范、评分政策和 Product Manifest 可编辑 Draft；发布后不可修改。
+- Release 内容行不可修改。撤回只改变 Release 生命周期；升级必须创建新 Release。
+- 已开始会话锁定 Revision、Placement、Assessment Policy Version 和分值证据。

+## 目标配置样例
+
+以下是种子/管理接口应表达的配置意图，不是在线授权脚本。
+
+```json
+[
+  {
+    "business": "upgrade_education",
+    "selectionMode": "single_from_tenant_license",
+    "maxActiveTargets": 1,
+    "maxPrimaryTargets": 1,
+    "maxAlternateTargets": 0,
+    "cooldownDays": 30,
+    "requiredDimensions": ["exam_year", "exam_system", "administrative_area", "subject_track"]
+  },
+  {
+    "business": "civil_service",
+    "selectionMode": "base_plus_entitled_targets",
+    "includesBaseContent": true,
+    "maxActiveTargets": 16,
+    "maxPrimaryTargets": 1,
+    "requiredDimensions": ["exam_year", "exam_system", "paper_category", "administrative_area"]
+  },
+  {
+    "business": "postgraduate",
+    "selectionMode": "base_plus_primary_and_entitled_alternates",
+    "includesBaseContent": true,
+    "maxActiveTargets": 16,
+    "maxPrimaryTargets": 1,
+    "requiredDimensions": ["exam_year", "exam_system", "institution", "school", "major", "subject_code"]
+  }
+]

+
+## 发布和在线不变量
+
+发布在 Repeatable Read 事务内执行，并按“所有者 + 大纲版本”取得 PostgreSQL 事务级 advisory lock。发布器验证 Revision、评分政策和 Profile，使用慢速 DNF 判定器生成 Segment，在同一事务写 Release、候选行和 Outbox。相同 Profile 集合共享 Segment；候选 ordinal 在发布时稳定生成。
+
+访问编译器只接受当前租户和登录用户，从有效租户业务许可证、许可 Profile、V2 学生权益、Product Manifest、当前主/备目标和班级 Grant 生成 `EffectiveAccessProjection`。Redis/FusionCache 缓存 30 秒且关闭 fail-safe；缓存未命中回源 PostgreSQL，事实库失败时不返回过期授权。
+
+创建会话最终只能执行：
+
+1. 获取一个 `EffectiveAccessProjection`。
+2. 验证请求资源被其中的 Manifest 允许。
+3. 按 Release、Segment、课程节点和稳定随机种子读取候选。
+4. 批量锁定交付版本和评分证据、原子扣减额度、创建会话。
+
+答题期间不再查询套餐、班级、老师、目标层级或内容规则。强撤权版本仍在答题和交卷入口检查。
+
+## PostgreSQL 选择
+
+- `ltree`：行政区、院校等单父层级目标节点及祖先/后代匹配。
+- 邻接表 + 闭包表：大纲节点；支持同一知识概念出现在不同大纲。
+- `pg_trgm`：所有者范围内的疑似重复题检索。
+- 原生月分区：答案尝试、访问事件和 Outbox。
+- 不使用 `ORDER BY random()`；按稳定 ordinal、种子起点和区间回绕采样。
+
+首版不引入 Citus、图数据库、Roaring Bitmap 或 pgvector。它们不会参与权限判定或在线刷题。
+
+## 基线重建要求
+
+删除 V1 内容/地区授权模型和旧迁移后，新的单一 `InitialSchema` 必须重新包含租户隔离函数与触发器、SaaS 防护对象、特殊 GIN/GiST/部分索引和月分区对象。空 PostgreSQL 执行 DbMigrator 后必须无待生成迁移。开发数据不迁移，种子按上述配置重新生成。
