Implemented Component 17 of the Spaxel plan - a pre-deployment simulator
that allows users to define virtual spaces, place virtual nodes, and
simulate walkers to predict detection quality before purchasing hardware.
Key features:
- Virtual space definition with rooms and wall segments
- Virtual node placement with corner positioning suggestions
- Synthetic walkers (random walk and path-following modes)
- GDOP (Geometric Dilution of Precision) computation for coverage quality
- Two-ray RF propagation model (direct + first-order reflection)
- Wall penetration loss by material type (drywall, brick, concrete, glass, metal)
- Fresnel zone computation and zone decay
- Shopping list generation with hardware recommendations
- REST API endpoints for simulation control and results
Files added:
- internal/simulator/space.go - Virtual space and room definitions
- internal/simulator/node.go - Virtual node management
- internal/simulator/walker.go - Synthetic walker simulation
- internal/simulator/gdop.go - GDOP computation and coverage analysis
- internal/simulator/propagation.go - RF propagation model
- internal/simulator/engine.go - Simulation engine (bug fixes)
- internal/simulator/handler.go - HTTP API handlers
- internal/api/simulator.go - REST API endpoints
- internal/simulator/simulator_test.go - Comprehensive tests
- internal/simulator/space_test.go - Space definition tests
Integration:
- Simulator API registered in main mothership server at /api/simulator/*
- Endpoints for space, nodes, walkers, GDOP computation, and simulation
