feat: Issue #42 - Nexus Architect for autonomous Three.js world building
Implement Phase 31: Autonomous 'Nexus' Expansion & Architecture DELIVERABLES: - agent/nexus_architect.py: AI agent for natural language to Three.js conversion * Prompt engineering for LLM-driven immersive environment generation * Mental state integration for dynamic aesthetic tuning * Mood preset system (contemplative, energetic, mysterious, etc.) * Room and portal design generation - tools/nexus_build_tool.py: Build tool interface with functions: * create_room(name, description, style) - Generate room modules * create_portal(from_room, to_room, style) - Generate portal connections * add_lighting(room, type, color, intensity) - Add Three.js lighting * add_geometry(room, shape, position, material) - Add 3D objects * generate_scene_from_mood(mood_description) - Mood-based generation * deploy_nexus_module(module_code, test=True) - Deploy and test - agent/nexus_deployment.py: Real-time deployment system * Hot-reload Three.js modules without page refresh * Validation (syntax check, Three.js API compliance) * Rollback on error with version history * Module versioning and status tracking - config/nexus-templates/: Template library * base_room.js - Base room template (Three.js r128+) * portal_template.js - Portal template (circular, rectangular, stargate) * lighting_presets.json - Warm, cool, dramatic, serene, crystalline presets * material_presets.json - 15 material presets including Timmy's gold, Allegro blue - tests/test_nexus_architect.py: Comprehensive test coverage * Unit tests for all components * Integration tests for full workflow * Template file validation DESIGN PRINCIPLES: - Modular architecture (each room = separate JS module) - Valid Three.js code (r128+ compatible) - Hot-reloadable (no page refresh needed) - Mental state integration (SOUL.md values influence aesthetic) NEXUS AESTHETIC GUIDELINES: - Timmy's color: warm gold (#D4AF37) - Allegro's color: motion blue (#4A90E2) - Sovereignty theme: crystalline structures, clean lines - Service theme: open spaces, welcoming lighting - Default mood: contemplative, expansive, hopeful

Nexus Build Tool
|
||||
|
||||
Build tool integration for the Three.js Nexus.
|
||||
Provides high-level functions for creating rooms, portals, lighting,
|
||||
and geometry with automatic code generation and validation.
|
||||
|
||||
Functions:
|
||||
- create_room(name, description, style) - Generate room module
|
||||
- create_portal(from_room, to_room, style) - Generate portal connection
|
||||
- add_lighting(room, type, color, intensity) - Add lighting
|
||||
- add_geometry(room, shape, position, material) - Add 3D objects
|
||||
- generate_scene_from_mood(mood_description) - Mood-based generation
|
||||
- deploy_nexus_module(module_code, test=True) - Deploy and test
|
||||
|
||||
Usage:
|
||||
from tools.nexus_build_tool import create_room, deploy_nexus_module
|
||||
|
||||
# Create room
|
||||
room = create_room(
