# ClickReflex - Comprehensive Technical Reference

## Technical Stack
- Framework: Next.js 16 (App Router)
- Language: TypeScript / React 19
- I18n: next-intl (Supports EN, ZH, DE, JA, PT-BR)
- Performance: ISR-enabled for dynamic leaderboards.

## Detailed Metrics & Tools

### 1. Input Lag Diagnostics
- **Mouse Polling Test**: Measures real-time reporting frequency (Hz) and jitter.
- **System Jitter Test**: Detects OS scheduling variance and DPC latency impacts.
- **Display Latency Test**: Visualizes frame delivery consistency and V-Sync/G-Sync impact.
- **Double Click Test**: Hardware-level detection for switch bouncing failures.

### 2. Reaction Benchmarks
- **Simple RT**: Baseline visual response time.
- **Choice RT**: Decision-making speed under multi-stimulus pressure.
- **Game Simulators**: Precision-calibrated reaction tests styled after Valorant and CS2 mechanics.

### 3. Cognitive Performance
- **Visual Memory**: Spatial recall and focus stability.
- **Sequence Memory**: Short-term logical chunking.
- **Stroop Test**: Cognitive interference and inhibitory control.

## Global Ranking & Normalization
ClickReflex uses Z-Score normalization to calibrate performance across different test modes.
Formula: `TGS = (Z_Score_Simple + Z_Score_Aim + Z_Score_Stroop) / 3`
This allows players to have a unified "Triathlon Global Score" (TGS) that is comparable globally.
