+## ETL Step 1:

+
+### 脚本说明
+- **脚本位置**: `ETL/L1A.py`
+- **功能**: 自动遍历 `output_arena` 目录下所有的 `iframe_network.json` 文件，提取原始内容并以 `match_id` (文件夹名) 为主键存入 `L1A.sqlite` 数据库的 `raw_iframe_network` 表中。
+
+### 运行方式

+# 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
+
+**预留中** - 无需任何文件或配置

+
+#### fact_match_players_t (2,080 rows, 101 columns)
+T-side specific player statistics
+- Same schema as fact_match_players
+- Filtered to T-side performance only
+
+### 3. Fact Tables - Round Level (3)
+
+#### fact_rounds (4,315 rows, 16 columns)
+Round-by-round match progression
+- Primary Key: (match_id, round_num)
+- Common Fields: winner_side, win_reason, duration, scores
+- Leetify Fields: money_start (CT/T), begin_ts, end_ts

+#### fact_round_player_economy (5,930 rows, 13 columns)
+Economy state per player per round
+- Primary Key: (match_id, round_num, steam_id_64)
+- Leetify Data: start_money, equipment_value, loadout details
+- Classic Data: equipment_snapshot_json (serialized)
+- Economy Tracking: main_weapon, helmet, defuser, zeus
+- Performance: round_performance_score (leetify only)
+
+---
+
+## 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.

+
+## 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
