# Perseus Efficiency — Dashboard Infographic

## Data Points (Verbatim)

**Cold → Warm Scaling (500 @query directives with 20ms work each):**
- Sequential cold: 11.5s
- Cached warm: 0.28s  
- Speedup: 40×
- Warm render time is CONSTANT regardless of query count

**Real-World Benchmarks:**
- Mega-Enterprise (500 microservices, 50 databases, 30 CI pipelines): 1.7s cold render, 722 lines, 48KB
- Mixed Real-World (9 git repos): 1.3s cold render, 291 lines, 24KB

**Stdout Safety:**
- 12MB scanner output capped at 256KB (47× reduction) with visible truncation marker

**Bug Fixes (Windows compatibility):**
- 4 Windows bugs fixed: emoji encoding, /bin/bash fallback, binary stdout crash, --help crash

**Test Suite:**
- 539 tests passing, 1 skipped

**Features Shipped:**
- @cache ttl=N → 40× warm speedup
- max_query_bytes → prevents stdout bombs
- timeout=N → per-directive timeout control
- parallel_queries / parallel_services → concurrent resolution (opt-in)

## Visual Layout

### Top Banner
"PERSEUS EFFICIENCY" with subtitle "Cold-Start Eliminated — Facts Before the First Prompt"

### Left Panel: Scaling Curve
Bar chart or line chart showing:
- X-axis: Number of @query directives (10, 50, 100, 200, 500)
- Two lines: Sequential Cold (blue, rising) vs Cached Warm (green, flat at 0.28s)
- Annotate the 500 point: "40×"

### Center Panel: Key Metrics (KPI cards)
- Large number: "40×" — Warm speedup
- Large number: "47×" — Stdout reduction  
- Large number: "1.7s" — 500-service enterprise audit
- Large number: "539" — Tests passing

### Right Panel: Real-World Impact
- Mega-Enterprise: 788 discovery calls → 0 after render
- Mixed Real-World: 76 cd-and-query ops → 0 after render
- "The assistant opens every session already oriented"

### Bottom: Feature Bar
- @cache ttl= | max_query_bytes | timeout= | parallel_* | Windows fixes

## Style Notes
- Dark blueprint background (navy/blue)
- White and cyan technical annotations
- Grid lines, measurement marks
- Engineering/schematic aesthetic
- Large bold numbers for metrics
- Clean, precise typography
