# Reachability Mini-Map Visualization API

## Module
Scanner

## Status
IMPLEMENTED

## Description
Extracts a compact mini-map from full reachability graphs, providing a simplified topological view (MiniMapNode, MiniMapPath models) for quick visual orientation. Distinct from existing "Reachability Subgraph Extraction" which is about proof-of-exposure, not UI visualization.

## Implementation Details
- **Mini-Map Extractor**:
  - `src/Scanner/__Libraries/StellaOps.Scanner.Reachability/MiniMap/MiniMapExtractor.cs` - `MiniMapExtractor` extracts compact mini-map representations from full reachability graphs for quick visual orientation
  - `src/Scanner/__Libraries/StellaOps.Scanner.Reachability/MiniMap/ReachabilityMiniMap.cs` - `ReachabilityMiniMap` model containing `MiniMapNode` and `MiniMapPath` structures for simplified topological views

## E2E Test Plan
- [ ] Generate a mini-map from a reachability graph and verify it contains simplified nodes and paths
- [ ] Verify the mini-map correctly preserves the topological structure (entrypoints, intermediate hops, vulnerable sinks)
- [ ] Verify the mini-map node count is significantly smaller than the full reachability graph
- [ ] Verify mini-map paths include key metadata (gate types, confidence levels) for each path segment
- [ ] Verify the API returns the mini-map in a format suitable for UI rendering (JSON with coordinates/layout hints)
