- Registry coordinate system: X=width, Y=height, Z=depth
- Simulator coordinate system: X=width, Y=depth, Z=height
- Y and Z axes are swapped between systems
- registry_bridge.go passes positions without coordinate transformation
- Required fix: swap Y and Z when calling registry methods
- Affects fusion engine, coverage optimization, and position-based tracking
Acceptance criteria:
- Registry's expected position format is documented ✅
- Actual format from simulator is documented ✅
- Format differences are identified ✅
- Required transformations are documented ✅
