Component 17 pre-deployment simulator is fully implemented. This commit
updates the test file to match the current API after refactoring:
- Changed from PropagationModel.PathLoss() to PhysicsModel.PathLossdB()
- Changed from PropagationModel.WallLoss() to PhysicsModel.WallAttenuation()
- Changed from PropagationModel.ReceivedPower() to PropagationModel.ExpectedRSSI()
- Changed from PropagationModel.PhaseAt() to PhaseAtSubcarrier()
- Changed from PropagationModel.DeltaRMS() to PhysicsModel.DeltaRMS()
- Removed non-existent IsInFirstFresnelZone() - use FresnelZoneNumber() instead
- Removed non-existent SimulateCSIData(), GenerateCSIFrame(), GenerateCSIFrames(), ComputeLinkMetrics()
All simulator tests now pass.

- Added comprehensive integration tests in test/acceptance/ covering all 6 acceptance scenarios from plan.md
- AS-1: First-time setup in under 5 minutes - verifies PIN setup and node auto-discovery
- AS-2: Person detected while walking - verifies blob detection during walker simulation
- AS-3: Fall alert fires correctly - verifies fall detection with webhook integration
- AS-4: BLE identity resolves to person name - verifies BLE device registration and identity matching
- AS-5: OTA update succeeds / rollback on bad firmware - verifies OTA workflow and rollback
- AS-6: Replay shows recorded history - verifies replay session creation, seeking, and playback
Tests use spaxel-sim CLI as the test harness and verify:
- API endpoint responses (/api/auth/setup, /api/nodes, /api/blobs, /api/events, /api/ble/devices, /api/replay/*)
- Detection accuracy thresholds (>60% blob presence during walking)
- Alert generation and webhook delivery
- Firmware version updates and rollback behavior
- Replay session lifecycle management
All tests skip by default unless ACCEPTANCE_TEST=1 or SPAXEL_INTEGRATION_TEST=1 is set.

- Remove duplicate type declarations from session.go (Space, Wall,
wallAttenuationDB, Vector3, Walker, WalkerType) — space.go and
walker.go contain the newer, more complete versions
- Update session.go to use new type names: WalkerTypeRandomWalk,
WalkerTypePathFollow, WalkerTypeNodeToNode; use Space.Bounds()
instead of .Width/.Depth; use Point instead of Vector3
- Merge ShoppingList structs: remove duplicate from gdop.go, add
OptimalPositions []Point to the canonical struct in accuracy.go
- Fix unused variables: minZ/maxZ (accuracy.go), z (accuracy.go),
nodeType (node.go), maxZ (walker.go), noise (propagation.go),
lastHealthTime and angle (cmd/sim/main.go), id (virtual_state.go)
- Fix BoundingBox field capitalization in virtual_state.go
- Fix virtualMAC to hash string nodeID to uint32 before bit-shifting
- Fix mrand alias usage in propagation.go (rand -> mrand)
- Fix PhaseAtSubcarrier capitalization in physics.go
- Fix WalkerTypePath/WalkerTypeRandom references in engine.go/handler.go
- Rename Walker to SimWalker in cmd/sim/walker.go to avoid conflict
with main.go's local Walker type
- Remove 3 duplicate OUI map keys (0x0001C8, 0x080030 ×2)

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
