+# 三层数据库架构重构计划
+
+## 一、项目背景与目标
+
+### 现状分析
+- **已有三层架构**: L1A(原始JSON) → L2(结构化事实/维度表) → L3(特征集市)
+- **主要问题**:
+  1. 数据库文件命名不统一(L1A.sqlite, L2_Main.sqlite, L3_Features.sqlite)
+  2. JSON中存在两种Round数据格式(leetify含经济数据, classic含xyz坐标), 目前通过`data_source_type`标记但未完全统一Schema
+  3. web/services层包含大量数据处理逻辑(feature_service.py 2257行, stats_service.py 1113行), 应下沉到数据库构建层
+  4. L2_Builder.py单体文件1470行,缺乏模块化
+
+### 重构目标
+1. **标准化命名**: 统一数据库文件为`L1.db`, `L2.db`, `L3.db`
+2. **Schema优化**: 设计统一Round数据表结构,支持多数据源差异化字段
+3. **逻辑下沉**: 将聚合计算从web/services迁移至database层的processor模块
+4. **模块化解耦**: 建立sub-processor模式,按功能域拆分处理器
+5. **预留L1B**: 为未来Demo直接解析管道预留目录结构
+
+---
+

+
+## 三、L2层Schema优化
+
+### 3.1 Round数据统一Schema设计
+
+**核心思路**: 设计包含所有字段的统一表结构,根据`data_source_type`选择性填充
+
+#### 3.1.1 fact_rounds表增强
+```sql
+CREATE TABLE IF NOT EXISTS fact_rounds (
+    match_id TEXT,
+    round_num INTEGER,
+    
+    -- 公共字段(两种数据源均有)
+    winner_side TEXT CHECK(winner_side IN ('CT', 'T', 'None')),
+    win_reason INTEGER,
+    win_reason_desc TEXT,
+    duration REAL,
+    ct_score INTEGER,
+    t_score INTEGER,
+    
+    -- Leetify专属字段
+    ct_money_start INTEGER,        -- 仅leetify
+    t_money_start INTEGER,         -- 仅leetify
+    begin_ts TEXT,                 -- 仅leetify
+    end_ts TEXT,                   -- 仅leetify
+    
+    -- Classic专属字段
+    end_time_stamp TEXT,           -- 仅classic
+    final_round_time INTEGER,      -- 仅classic
+    pasttime INTEGER,              -- 仅classic
+    
+    -- 数据源标记(继承自fact_matches)
+    data_source_type TEXT CHECK(data_source_type IN ('leetify', 'classic', 'unknown')),
+    
+    PRIMARY KEY (match_id, round_num),
+    FOREIGN KEY (match_id) REFERENCES fact_matches(match_id) ON DELETE CASCADE
+);
+```
+
+#### 3.1.2 fact_round_events表增强
+```sql
+CREATE TABLE IF NOT EXISTS fact_round_events (
+    event_id TEXT PRIMARY KEY,
+    match_id TEXT,
+    round_num INTEGER,
+    
+    event_type TEXT CHECK(event_type IN ('kill', 'bomb_plant', 'bomb_defuse', 'suicide', 'unknown')),
+    event_time INTEGER,
+    
+    -- Kill相关字段
+    attacker_steam_id TEXT,
+    victim_steam_id TEXT,
+    assister_steam_id TEXT,
+    flash_assist_steam_id TEXT,
+    trade_killer_steam_id TEXT,
+    
+    weapon TEXT,
+    is_headshot BOOLEAN DEFAULT 0,
+    is_wallbang BOOLEAN DEFAULT 0,
+    is_blind BOOLEAN DEFAULT 0,
+    is_through_smoke BOOLEAN DEFAULT 0,
+    is_noscope BOOLEAN DEFAULT 0,
+    
+    -- Classic空间数据(xyz坐标)
+    attacker_pos_x INTEGER,       -- 仅classic
+    attacker_pos_y INTEGER,       -- 仅classic
+    attacker_pos_z INTEGER,       -- 仅classic
+    victim_pos_x INTEGER,         -- 仅classic
+    victim_pos_y INTEGER,         -- 仅classic
+    victim_pos_z INTEGER,         -- 仅classic
+    
+    -- Leetify评分影响
+    score_change_attacker REAL,   -- 仅leetify
+    score_change_victim REAL,     -- 仅leetify
+    twin REAL,                    -- 仅leetify (team win probability)
+    c_twin REAL,                  -- 仅leetify
+    twin_change REAL,             -- 仅leetify
+    c_twin_change REAL,           -- 仅leetify
+    
+    -- 数据源标记
+    data_source_type TEXT CHECK(data_source_type IN ('leetify', 'classic', 'unknown')),
+    
+    FOREIGN KEY (match_id, round_num) REFERENCES fact_rounds(match_id, round_num) ON DELETE CASCADE
+);
+```
+
+#### 3.1.3 fact_round_player_economy表增强
+```sql
+CREATE TABLE IF NOT EXISTS fact_round_player_economy (
+    match_id TEXT,
+    round_num INTEGER,
+    steam_id_64 TEXT,
+    
+    side TEXT CHECK(side IN ('CT', 'T')),
+    
+    -- Leetify经济数据(仅leetify)
+    start_money INTEGER,
+    equipment_value INTEGER,
+    main_weapon TEXT,
+    has_helmet BOOLEAN,
+    has_defuser BOOLEAN,
+    has_zeus BOOLEAN,
+    round_performance_score REAL,
+    
+    -- Classic装备快照(仅classic, JSON存储)
+    equipment_snapshot_json TEXT,  -- Classic的equiped字段序列化
+    
+    -- 数据源标记
+    data_source_type TEXT CHECK(data_source_type IN ('leetify', 'classic', 'unknown')),
+    
+    PRIMARY KEY (match_id, round_num, steam_id_64),
+    FOREIGN KEY (match_id, round_num) REFERENCES fact_rounds(match_id, round_num) ON DELETE CASCADE
+);
+```
+
+### 3.2 Force Buy修复
+
+在`fact_round_player_economy`表中确保:
+- `start_money`和`equipment_value`字段类型为INTEGER
+- 处理器中正确解析leetify的`bron_equipment`和`player_bron_crash`
+
+---
+
+## 四、L2 Processor模块化设计
+
+### 4.1 架构模式
+
+```
+L2_Builder.py (主控制器, ~300行)
+    ↓ 调用
+processors/
+    ├── match_processor.py       # 处理fact_matches, fact_match_teams
+    ├── player_processor.py      # 处理dim_players, fact_match_players
+    ├── round_processor.py       # 统一调度round数据处理
+    │   ├── 内部调用 economy_processor
+    │   ├── 内部调用 event_processor
+    │   └── 内部调用 spatial_processor
+    ├── economy_processor.py     # 专门处理leetify经济数据
+    ├── event_processor.py       # 处理kill/bomb事件
+    └── spatial_processor.py     # 处理classic坐标数据
+```
+
+### 4.2 Processor接口规范
+
+每个processor模块提供标准接口:
+```python
+class XxxProcessor:
+    @staticmethod
+    def process(match_data: MatchData, conn: sqlite3.Connection) -> bool:
+        """
+        Args:
+            match_data: 统一的MatchData对象(包含所有原始数据)
+            conn: L2数据库连接
+        Returns:
+            bool: 处理成功返回True

+
+### 5.3 L3_Builder重构结构
+
+```python
+# L3_Builder.py (瘦身至~150行)
+from database.L3.processors import (
+    basic_processor,
+    sta_processor,
+    bat_processor,
+    hps_processor,
+    ptl_processor,
+    side_processor,
+    util_processor,
+    eco_processor,
+    pace_processor
+)
+
+def rebuild_all_features():
+    conn_l2 = sqlite3.connect(L2_DB_PATH)
+    conn_l3 = sqlite3.connect(L3_DB_PATH)
+    
+    players = get_all_players(conn_l2)
+    
+    for player in players:
+        features = {}
+        
+        # 调用各processor
+        features.update(basic_processor.calculate(player, conn_l2))
+        features.update(sta_processor.calculate(player, conn_l2))
+        features.update(bat_processor.calculate(player, conn_l2))

+        features.update(eco_processor.calculate(player, conn_l2))
+        features.update(pace_processor.calculate(player, conn_l2))
+        
+        # 写入L3
+        upsert_player_features(conn_l3, player['steam_id_64'], features)
+    
+    conn_l2.close()
+    conn_l3.close()
+```
+
+---
+
+## 六、Web Services解耦
+
+### 6.1 迁移策略
+
+**原则**: Web层只做查询和缓存,不做计算
+
+#### feature_service.py重构
+- **保留功能**:
+  - `get_player_features(steam_id)`: 从L3查询
+  - `get_players_list()`: 分页查询
+- **移除功能**(迁移到L3 processors):
+  - `rebuild_all_features()` → L3_Builder.py
+  - 所有`_calculate_xxx()`方法 → L3/processors/xxx_processor.py
+
+#### stats_service.py重构
+- **保留功能**:
+  - `get_player_basic_stats()`: 简单查询L2
+  - `get_match_details()`: 查询比赛详情
+- **优化功能**:
+  - `get_team_stats_summary()`: 改为查询L2 VIEW(新建聚合视图)
+  - 复杂聚合逻辑移至L2 processors或创建数据库VIEW
+
+### 6.2 新建L2 VIEW
+
+在`database/L2/schema.sql`中新增:
+
+```sql
+-- 玩家全场景统计视图
+CREATE VIEW IF NOT EXISTS v_player_all_stats AS
+SELECT 
+    steam_id_64,
+    COUNT(DISTINCT match_id) as total_matches,
+    AVG(rating) as avg_rating,
+    AVG(kd_ratio) as avg_kd,
+    AVG(kast) as avg_kast,
+    SUM(kills) as total_kills,
+    SUM(deaths) as total_deaths,
+    SUM(assists) as total_assists,
+    SUM(mvp_count) as total_mvps
+FROM fact_match_players
+GROUP BY steam_id_64;
+
+-- 地图维度统计视图
+CREATE VIEW IF NOT EXISTS v_map_performance AS
+SELECT 
+    fmp.steam_id_64,
+    fm.map_name,
+    COUNT(*) as matches_on_map,
+    AVG(fmp.rating) as avg_rating,
+    AVG(fmp.kd_ratio) as avg_kd,
+    SUM(CASE WHEN fmp.is_win THEN 1 ELSE 0 END) * 1.0 / COUNT(*) as win_rate
+FROM fact_match_players fmp
+JOIN fact_matches fm ON fmp.match_id = fm.match_id
+GROUP BY fmp.steam_id_64, fm.map_name;
+```
+
+---
+
+## 七、数据流与交叉引用
+
+### 7.1 数据流示意图
+
+```
+原始数据(output_arena/*/iframe_network.json)
+    ↓
+【L1层】L1.db: raw_iframe_network (1张表)
+    └─ match_id (PK)

+    ↓
+【L2层】L2.db: 9张核心表
+    ├─ dim_players (玩家维度, 75个字段)

+
+## 九、风险与注意事项
+
+### 9.1 数据一致性
+- **风险**: 重构过程中Schema变化可能导致旧数据不兼容
+- **缓解**: 
+  - 使用`Force_Rebuild.py`全量重建
+  - 保留L1原始数据,随时可回溯
+
+### 9.2 性能影响
+- **风险**: Processor模块化可能增加函数调用开销
+- **缓解**:
+  - 批量处理(一次处理多个match)
+  - 使用executemany()优化INSERT
+  - 关键路径使用SQL聚合而非Python循环
+
+### 9.3 Leetify vs Classic覆盖率
+- **风险**: 部分特征(如eco, spatial)仅单数据源可用
+- **缓解**:
+  - 在processor中判断data_source_type
+  - 不可用特征标记为NULL
+  - 文档中明确标注依赖
+
+### 9.4 Web服务中断
+- **风险**: feature_service重构可能影响线上功能
+- **缓解**:
+  - 先完成L2/L3 processor,再改web层
+  - 使用特性开关(feature flag)
+  - 灰度发布
+

+# YRTV 项目说明 till 1.0.2hotfix
+
+## 项目概览
+YRTV 是一个基于 CS2 比赛数据的综合分析与战队管理平台。它集成了数据采集、ETL 清洗建模、特征挖掘以及现代化的 Web 交互界面。
+核心目标是为战队提供数据驱动的决策支持，包括战术分析、队员表现评估、阵容管理（Clubhouse）以及实时战术板功能。
+
+---
+
+您可以使用以下命令快速配置环境：
+pip install -r requirements.txt
+
+数据来源与处理核心包括：
+- 比赛页面的 iframe JSON 数据（`iframe_network.json`）
+- 可选的 demo 文件（`.zip/.dem`）
+- L1A/L2/L3 分层数据库建模与校验
+
+## v3.0.0 Release 更新要点
+- **核心算法升级**: 严格确立 Active Roster (Lineup 1) 为战队平均数据计算基准，修复了雷达图与平均数据的计算偏差。
+- **Clubhouse 增强**: 
+    - 布局优化为 3 列网格。
+    - 新增 **OVR (Overall Score)** 显示，优先展示真实评分 (Real Rating)，直观反映选手综合实力。
+- **Tactics 系统**: 
+    - 统一评分逻辑：全站优先采用 L3 `core_avg_rating2` (真实评分)，智能回退至 `basic_avg_rating`。
+    - Data Center 数据中心现在完整映射了 Utility、Trading 等高阶战术数据。
+- **稳定性修复**: 修正了特征服务中的语法错误，增强了对缺失数据的鲁棒性处理。
+
+## Web 交互系统 (Core)
+基于 Flask + TailwindCSS + Alpine.js 构建的现代化 Web 应用。
+
+### 核心功能模块

+展示项目业务价值的核心是打造**「技术动作→数据成果→业务落地」的闭环链路**，结合你CS2数据项目+数据分析岗的定位，同时匹配“队长带领5人团队”的角色，核心要做到**量化成果前置、技术与业务强绑定、个人贡献突出**，以下是可直接落地的方法，附专属你的CS2项目优化示例和通用模板：
+
+### 一、核心方法：5招落地，每招配CS2项目简历示例
+#### 1. 成果前置+强量化，抓牢HR8秒注意力
+把**最核心的业务价值**放在项目概述首位，用**对比量化（提升/降低）+绝对值量化（数据量/规模）** 替代模糊描述，电竞/数据分析岗重点突出**核心业务指标、数据处理规模、效率/成本优化**三类数据。
+**普通表述**：带领团队搭建CS2数据平台，处理了大量比赛数据，提升了战队胜率
+**优化表述**：作为队长带领5人数据团队，搭建CS2赛事全流程数据分析平台，完成1年内300+场职业比赛、1600+玩家、数十万回合级数据的结构化处理，**推动战队ELO分层胜率从42%提升至55%（+13个百分点）**，数据维护人力成本降低60%。
+
+#### 2. 技术动作与业务价值强绑定，拒绝纯技术堆砌
+数据分析岗最忌只说“用Python做数据处理”，要明确**Python的具体高阶操作→带来的数据分析成果→最终落地的业务价值**，让技术成为业务价值的“桥梁”，而非孤立的技能。
+**普通表述**：用Python做了数据清洗和特征工程，构建了玩家画像
+**优化表述**：通过Python（Pandas/NumPy）实现原始JSON赛事数据的**矢量化清洗与批处理转换**，结合窗口函数完成200+维度玩家画像的高效计算，创新定义“压力表现”等战术指标，**为战队战术组提供精准的选手适配、站位优化数据支撑，成为胜率提升的核心数据依据**。
+
+#### 3. STAR法则结构化，让业务价值链路更清晰
+围绕电竞行业**“经验驱动战术→缺乏精细化数据支撑”**的核心痛点搭建STAR框架，**情境(S)讲行业/业务痛点，任务(T)定团队目标+个人职责，行动(A)做技术+数据动作，结果(R)出业务+效率双成果**，同时突出队长的**团队统筹能力**。
+**CS2项目STAR落地示例**：
+- 情境(S)：针对电竞行业战术决策依赖经验、传统K/D指标无法量化战术价值的痛点，战队ELO分层胜率长期低于行业平均水平；
+- 任务(T)：带领5人团队搭建从数据采集到可视化的全流程分析平台，核心目标通过数据驱动战术优化提升战队胜率；
+- 行动(A)：统筹团队分工（数据采集/特征工程/可视化），制定Python代码规范，主导设计L1-L3分层数仓，开发Python多线程ETL自动化流水线；
+- 结果(R)：战队ELO分层胜率提升13%，300+场比赛数据实现实时入库，数据查询效率提升至毫秒级，团队开发效率提升40%。
+
+#### 4. 多维度拆解业务价值，让成果更立体
+单一的胜率提升不够有说服力，结合数据分析岗的**效率、成本、复用性**，从**核心业务指标（胜率）、数据效率（处理/查询速度）、运营成本（人力/时间）、成果复用性（模型/指标的落地）**四个维度拆解，贴合企业对数据“降本增效+业务赋能”的核心需求。
+**CS2项目多维度价值示例**：
+- 业务效果：ELO分层胜率42%→55%，战术优化精准度提升80%；
+- 数据效率：Python矢量化处理让1600+玩家全维度数据查询效率提升至毫秒级；
+- 成本优化：Python自动化ETL流水线让数据维护人力成本降低60%，赛事数据入库时间从小时级压缩至分钟级；
+- 成果复用：搭建的200+维度玩家特征模型被战队战术组复用，成为日常战术分析、选手选拔的标准模型。
+
+#### 5. 嵌入行业专属术语，让专业度拉满
+在描述中加入**电竞行业+数据分析岗**的专属术语，让HR/业务方快速感知你对双领域的理解，避免“外行话”，核心术语精准即可，无需堆砌。
+- 电竞行业：ELO分层胜率、战术复盘、玩家协同效率、阵容适配、回合级数据；
+- 数据分析岗：L1-L3分层数仓、特征工程、ETL自动化流水线、矢量化运算、玩家画像特征集市。
+
+### 二、数据分析岗专属：「技术-业务」价值句式模板
+直接套用来描述项目职责，完美实现技术动作与业务价值的绑定，适配你的CS2项目所有模块：

+**技能关键词**：Python（Pandas/NumPy/多线程/矢量化运算）、SQLite、SQL、ETL自动化、数据仓库设计、特征工程、Playwright、Flask、团队管理、电竞赛事数据分析
+
+### 五、高端项目启发：从电竞数据项目到企业级数据项目的业务价值思维
+你的CS2项目已经具备企业级高端数据项目的核心雏形，高端项目对**业务价值**的要求会更强调**「规模化、可复用、商业变现」**，核心启发有3点：
+1. **从“单战队价值”到“行业规模化价值”**：企业级项目不仅服务单一业务方，而是能复用到整个行业/公司多业务线，比如你的CS2特征模型可从单战队拓展至青训选手选拔、赛事直播数据可视化、电竞俱乐部数据中台搭建；
+2. **从“战术价值”到“商业价值”**：高端项目需将数据价值转化为**可量化的商业收益**，比如电竞数据平台可通过为赛事方/俱乐部提供付费数据分析服务、为品牌方提供选手粉丝画像实现商业变现，企业中则是将数据成果转化为GMV提升、营收增长、获客成本降低；
+3. **从“人工落地”到“自动化决策”**：你的项目实现了“数据支撑战术决策”，高端项目会进一步实现**“数据自动化输出决策建议”**，比如通过Python搭建实时战术推荐模型，比赛中根据战局动态输出最优站位/道具使用建议，企业中则是智能推荐、自动化风控、精准营销等场景。

+# L1B层 - 预留目录
+
+## 用途说明
+
+本目录为**预留**目录,用于未来的Demo直接解析管道。
+
+### 背景
+
+当前数据流:
+```
+output_arena/*/iframe_network.json → L1(raw JSON) → L2(structured) → L3(features)
+```
+
+### 未来规划
+
+L1B层将作为另一条数据管道的入口:
+```
+Demo文件(*.dem) → L1B(Demo解析后的结构化数据) → L2 → L3
+```
+
+### 为什么预留?
+
+1. **数据源多样性**: 除了网页抓取的JSON数据,未来可能需要直接从CS2 Demo文件中提取更精细的数据(如玩家视角、准星位置、投掷物轨迹等)
+2. **架构一致性**: 保持L1A和L1B作为两个平行的原始数据层,方便后续L2层统一处理
+3. **可扩展性**: Demo解析可提供更丰富的空间和时间数据,为L3层的高级特征提供支持
+
+### 实施建议
+
+当需要启用L1B时:
+1. 创建`L1B_Builder.py`用于Demo文件解析
+2. 创建`L1B.db`存储解析后的数据
+3. 修改L2_Builder.py支持从L1B读取数据
+4. 设计L1B schema以兼容现有L2层结构
+
+### 当前状态

+
+## Data Processing Architecture
+
+### Modular Processor Pattern
+
+The L2 build uses a 6-processor architecture:
+
+1. **match_processor**: fact_matches, fact_match_teams
+2. **player_processor**: dim_players, fact_match_players (all variants)
+3. **round_processor**: Dispatcher based on data_source_type
+4. **economy_processor**: fact_round_player_economy (leetify data)
+5. **event_processor**: fact_rounds, fact_round_events (both sources)
+6. **spatial_processor**: xyz coordinate extraction (classic data)
+
+### Data Source Multiplexing
+
+The schema supports two data sources:
+- **Leetify**: Rich economy data, scoring metrics, performance analysis
+- **Classic**: Spatial coordinates, detailed equipment snapshots
+
+Each fact table includes `data_source_type` field to track data origin.
+
+---
+
+## Key Technical Achievements
+
+### 1. Fixed Column Count Mismatches
+- Implemented dynamic SQL generation for INSERT statements
+- Eliminated manual placeholder counting errors
+- All processors now use column lists + dynamic placeholders
+
+### 2. Resolved Processor Data Flow
+- Added `data_round_list` and `data_leetify` to MatchData
+- Processors now receive parsed data structures, not just raw JSON
+- Round/event processing now fully functional
+
+### 3. 100% Data Coverage
+- All L1 JSON fields mapped to L2 tables
+- No data loss during transformation
+- Raw JSON preserved in fact_matches for reference
+
+### 4. Comprehensive Schema
+- 10 tables total (2 dimension, 8 fact)
+- 51,860 rows of structured data
+- 400+ distinct columns across all tables
+
+---
+
+## Files Modified
+
+### Core Builder
+- `database/L1/L1_Builder.py` - Fixed output_arena path
+- `database/L2/L2_Builder.py` - Added data_round_list/data_leetify fields
+
+### Processors (Fixed)
+- `database/L2/processors/match_processor.py` - Dynamic SQL generation
+- `database/L2/processors/player_processor.py` - Dynamic SQL generation
+
+### Analysis Tools (Created)
+- `database/L2/analyze_coverage.py` - Coverage analysis script
+- `database/L2/extract_schema.py` - Schema extraction tool
+- `database/L2/L2_SCHEMA_COMPLETE.txt` - Full schema documentation
+
+---
+
+## Next Steps
+
+### Immediate
+- L3 processor development (feature calculation layer)
+- L3 schema design for aggregated player features
+
+### Future Enhancements
+- Add spatial analysis tables for heatmaps
+- Expand event types beyond kill/bomb
+- Add derived metrics (clutch win rate, eco round performance, etc.)
+
+---
+
+## Conclusion
+
+The L2 database layer is **production-ready** with:
+- ✅ 100% L1→L2 transformation coverage
+- ✅ Zero data loss
+- ✅ Dual data source support (leetify + classic)
+- ✅ Comprehensive 10-table schema
+- ✅ Modular processor architecture
+- ✅ 51,860 rows of high-quality structured data
+
+The foundation is now in place for L3 feature engineering and web application queries.

+# L3 Implementation Roadmap & Checklist
+
+> **Based on**: L3_ARCHITECTURE_PLAN.md v2.0  
+> **Start Date**: 2026-01-28  
+> **Estimated Duration**: 8-10 days
+
+---
+
+## Quick Start Checklist
+
+### ✅ Pre-requisites
+- [x] L1 database完整 (208 matches)
+- [x] L2 database完整 (100% coverage, 51,860 rows)
+- [x] L2 schema documented
+- [x] Profile requirements analyzed
+- [x] L3 architecture designed
+
+### 🎯 Implementation Phases
+
+---
+
+## Phase 1: Schema & Infrastructure (Day 1-2)
+
+### 1.1 Create L3 Database Schema
+- [ ] Create `database/L3/schema.sql`
+  - [ ] dm_player_features (207 columns)
+  - [ ] dm_player_match_history
+  - [ ] dm_player_map_stats  
+  - [ ] dm_player_weapon_stats
+  - [ ] All indexes
+
+### 1.2 Initialize L3 Database
+- [ ] Update `database/L3/L3_Builder.py` init_db()
+- [ ] Run schema creation
+- [ ] Verify tables created
+
+### 1.3 Processor Base Classes
+- [ ] Create `database/L3/processors/__init__.py`
+- [ ] Create `database/L3/processors/base_processor.py`
+  - [ ] BaseFeatureProcessor interface
+  - [ ] SafeAggregator utility class
+  - [ ] Z-score normalization functions
+
+**验收标准**：
+```bash
+sqlite3 database/L3/L3.db ".tables"
+# 应输出: dm_player_features, dm_player_match_history, dm_player_map_stats, dm_player_weapon_stats
+```
+
+---
+
+## Phase 2: Tier 1 - Core Processors (Day 3-4)
+
+### 2.1 BasicProcessor Implementation
+- [ ] Create `database/L3/processors/basic_processor.py`
+
+**Sub-tasks**:
+- [ ] `calculate_basic_stats()` - 15 columns
+  - [ ] AVG(rating, rating2, kd, adr, kast, rws) from fact_match_players
+  - [ ] AVG(headshot_count), hs_rate = SUM(hs)/SUM(kills)
+  - [ ] total_kills, total_deaths, total_assists
+  - [ ] kpr, dpr, survival_rate
+  
+- [ ] `calculate_match_stats()` - 8 columns
+  - [ ] win_rate, wins, losses
+  - [ ] avg_match_duration from fact_matches
+  - [ ] avg_mvps, mvp_rate
+  - [ ] avg_elo_change, total_elo_gained from fact_match_teams
+  
+- [ ] `calculate_weapon_stats()` - 12 columns
+  - [ ] avg_awp_kills, awp_usage_rate
+  - [ ] avg_knife_kills, avg_zeus_kills, zeus_buy_rate
+  - [ ] top_weapon (GROUP BY weapon in fact_round_events)
+  - [ ] weapon_diversity (Shannon entropy)
+  - [ ] rifle/pistol/smg hs_rates
+  
+- [ ] `calculate_objective_stats()` - 6 columns
+  - [ ] avg_plants, avg_defuses, avg_flash_assists
+  - [ ] plant_success_rate, defuse_success_rate
+  - [ ] objective_impact (weighted score)
+
+**测试用例**:
+```python
+features = BasicProcessor.calculate('76561198012345678', conn_l2)
+assert 'core_avg_rating' in features
+assert features['core_total_kills'] > 0
+assert 0 <= features['core_hs_rate'] <= 1
+```
+
+---
+
+## Phase 3: Tier 2 - Tactical Processors (Day 4-5)
+
+### 3.1 TacticalProcessor Implementation
+- [ ] Create `database/L3/processors/tactical_processor.py`
+
+**Sub-tasks**:
+- [ ] `calculate_opening_impact()` - 8 columns
+  - [ ] avg_fk, avg_fd from fact_match_players
+  - [ ] fk_rate, fd_rate
+  - [ ] fk_success_rate (team win when FK)
+  - [ ] entry_kill_rate, entry_death_rate
+  - [ ] opening_duel_winrate
+  
+- [ ] `calculate_multikill()` - 6 columns

+
+## Risk Mitigation
+
+### 🔴 High Risk Items
+1. **Position Mastery (xyz clustering)**
+   - Mitigation: Start with simple grid-based approach, defer ML clustering
+   
+2. **Composite Score Standardization**
+   - Mitigation: Use simple percentile-based normalization as fallback
+   
+3. **Performance at Scale**
+   - Mitigation: Implement incremental updates, add indexes
+
+### 🟡 Medium Risk Items
+1. **Time Window Calculations (trades)**
+   - Mitigation: Use efficient self-JOIN with time bounds
+   
+2. **Missing Data Handling**
+   - Mitigation: Comprehensive NULL handling, default values
+
+### 🟢 Low Risk Items
+1. Basic aggregations (AVG, SUM, COUNT)
+2. Service layer refactoring
+3. Template updates
+
+---
+
+## Next Actions
+
+**Immediate (Today)**:
+1. Create schema.sql
+2. Initialize L3.db
+3. Create processor base classes
+
+**Tomorrow**:
+1. Implement BasicProcessor
+2. Test with sample player
+3. Start TacticalProcessor
+
+**This Week**:
+1. Complete all 5 processors
+2. Full L3_Builder run
+3. Service refactoring
+
+**Next Week**:
+1. Frontend integration
+2. Testing & validation
+3. Documentation
+
+---
+
+## Notes
+
+- 保持每个processor独立，便于单元测试
+- 使用动态SQL避免column count错误
+- 所有rate/percentage使用0-1范围存储，UI展示时乘100
+- 时间戳统一使用Unix timestamp (INTEGER)
+- 遵循"查询不计算"原则：web层只SELECT，不做聚合

+# JSON Schema Extractor
+
+用于从大量 5E Arena 比赛数据 (`iframe_network.json`) 中提取、归纳和分析 JSON Schema 的工具。它能够自动处理复杂的嵌套结构，识别动态 Key（如 SteamID、5E ID、Round Number），并生成层级清晰的结构报告。
+
+## ✨ 核心功能
+
+*   **批量处理**: 自动扫描并处理目录下的所有 `iframe_network.json` 文件。
+*   **智能归并**:
+    *   **动态 Key 掩码**: 自动识别并掩盖 SteamID (`<steamid>`)、5E ID (`<5eid>`) 和回合数 (`<round_n>`)。
+    *   **结构合并**: 自动将 `group_1`/`group_2` 合并为 `group_N`，将 `fight`/`fight_t`/`fight_ct` 合并为 `fight_any`。
+*   **多格式输出**:
+    *   `schema_summary.md`: 易于阅读的 Markdown 层级报告。
+    *   `schema_full.json`: 包含类型统计和完整结构的机器可读 JSON。
+    *   `schema_flat.csv`: 扁平化的 CSV 字段列表，方便 Excel 查看。
+*   **智能分类**: 根据 URL 路径自动将数据归类（如 Match Data, Leetify Rating, Round Data 等）。
+
+## 🚀 快速开始
+
+### 1. 运行提取器
+
+在项目根目录下运行：
+
+```bash
+# 使用默认配置 (输入: output_arena, 输出: output_reports/)
+python utils/json_extractor/main.py
+
+# 自定义输入输出
+python utils/json_extractor/main.py --input my_data_folder --output-md my_report.md
+```
+
+### 2. 查看报告
+
+运行完成后，在 `output_reports/` 目录下查看结果：
+
+*   **[schema_summary.md](../../output_reports/schema_summary.md)**: 推荐首先查看此文件，快速了解数据结构。
+*   **[schema_flat.csv](../../output_reports/schema_flat.csv)**: 需要查找特定字段（如 `adr`）在哪些层级出现时使用。
+
+## 🛠️ 规则配置
+
+核心规则定义在 `utils/json_extractor/rules.py` 中，你可以根据需要修改：
+
+*   **ID 识别**: 修改 `STEAMID_REGEX` 或 `FIVE_E_ID_REGEX` 正则。
+*   **URL 过滤**: 修改 `IGNORE_URL_PATTERNS` 列表以忽略无关请求（如 sentry 日志）。
+*   **Key 归并**: 修改 `get_key_mask` 函数来添加新的归并逻辑。
+
+## 📊 结构分析工具
+
+如果需要深入分析某些结构（如 `fight` 对象的变体），可以使用分析脚本：
+
+```bash
+python utils/json_extractor/analyze_structure.py
+```
+
+该脚本会统计特定字段的覆盖率，并检查不同 API（如 Round API 与 Leetify API）的共存情况。
