Updated README_scenario_design.md with new grid-based room layout system:
- Documented Grid Unit (GU) system: 5×4 tiles base unit
- Added valid room size specifications (widths: multiples of 5, heights: 2+4N)
- Replaced old north/south-only constraints with four-direction support
- Updated door placement rules for N/S/E/W connections
- Added room positioning algorithm documentation
- Revised scenario design guidelines for grid system flexibility
Created 5 comprehensive test scenarios:
1. test_vertical_layout.json - Traditional N/S stacking
2. test_horizontal_layout.json - E/W connections
3. test_complex_multidirection.json - All four directions
4. test_multiple_connections.json - Multiple doors per direction
5. test_mixed_room_sizes.json - Different room sizes (1×1, 1×2, 2×2 GU)
Added TEST_SCENARIOS_README.md documenting:
- Grid system overview and room size specifications
- Detailed test scenario descriptions with layout diagrams
- Testing procedures and validation checks
- Expected console output examples
- Troubleshooting guide
Note: Scenarios reference hall_1x2gu.json and small_room_1x1gu.json which
need to be created in assets/rooms/. Currently using 2×2 GU placeholders.
All test scenarios include:
- Visual layout diagrams in scenario_brief
- Progressive difficulty with locks and keys
- Documentation of what each scenario tests
- Notes explaining grid system concepts
