## 🏗️ Phase 8 Architecture Notes

### Option B: Hybrid AI + Rules Engine (SELECTED)

**Problem**: AI is unreliable at following D&D rules consistently
- Ignores spells player casts
- Allows spells player doesn't know
- Doesn't track resources (HP, spell slots)
- Makes up mechanics on the fly

**Solution**: Intercept player actions BEFORE AI sees them

**Flow**:
1. **Player Input**: "I cast Magic Missile at the goblin"
2. **Rules Engine** (Python code):
   - Parse: Detect spell casting intent
   - Validate: Check if player owns "Magic Missile" ✓
   - Validate: Check if player has 1st-level spell slot ✓
   - Retrieve: Get spell details from RAG (3 darts, 1d4+1 each)
   - Roll: 3d4+3 = 11 damage (programmatically)
   - Deduct: Spell slot consumed
   - Update: Target HP reduced by 11
3. **AI Prompt**: "You successfully cast Magic Missile dealing 11 force damage to the goblin. The goblin now has 5 HP remaining. Describe the magical missiles striking the goblin."
4. **AI Response**: (Just narrates the flavor, mechanics already handled)

**Benefits**:
- AI becomes a **narrator**, not a **rules engine**
- Mechanics are deterministic and accurate
- AI can focus on storytelling
- Players can trust the rules

**Alternatives Rejected**:
- **Option A** (Pure AI): Too unreliable, tested and failed
- **Option C** (Post-process AI): Too hard to fix bad outputs

- **Monsters**: Name appears 3× (MONSTER: name, name, **name**) + type extraction
- **Classes**: Name appears 3× (CLASS: name, name, **name**)
- **Races**: Name appears 3× (RACE: name, name, **name**) + trait extraction

### ✅ Multiple Chunk Types Per Entity
- **Spells**: full_spell, quick_reference, by_class
- **Monsters**: monster_stats with type tags
- **Classes**: class_features
- **Races**: race_description, race_traits

### ✅ Rich Metadata
- **Spells**: level, school, casting_time, range, components, duration, classes, ritual, concentration
- **Monsters**: challenge_rating, monster_type (size + type), type tags
- **Classes**: name, content_type
- **Races**: ability_increases, size, speed, darkvision, languages

## 📝 Notes & Decisions

### Design Decisions
- **Database**: ChromaDB for persistence and semantic search
- **Embeddings**: sentence-transformers/all-MiniLM-L6-v2 for speed/quality balance
- **LLM**: Ollama with Qwen3-4B-RPG-Roleplay-V2 for D&D-tuned responses
- **Collection Strategy**: Separate collections per content type for clean organization
- **Name Weighting**: Entity names repeated 2-3× at chunk start for better exact-match retrieval
- **Multiple Chunks**: Each entity creates multiple specialized chunks for different use cases

### Key Improvements (Nov 6, 2024)
1. ✅ **Spell Parser Upgrade** - Now uses sophisticated `SpellParser` class instead of inline code
2. ✅ **Name Weighting** - All entity types now have weighted names for better retrieval
3. ✅ **Race Extraction** - Full race data extracted from PDF with traits and metadata
4. ✅ **Monster Type Extraction** - Automatic extraction of size and creature type
5. ✅ **Interactive Query Tool** - New CLI for exploring the RAG system
6. ✅ **Comprehensive Tests** - 26+ automated tests validating all functionality

### Known Issues (Phase 8 Discovery - Dec 1, 2024)
- **AI Unreliability**: Pure AI approach fails to consistently enforce D&D rules
  - Ignores valid spell casts (Magic Missile cast was turned into melee combat)
  - Allows invalid spells (Let Elara cast Fireball, which she doesn't know)
  - No resource tracking (spell slots, HP, gold)
- **Solution**: Moving to Hybrid Architecture (Option B) with programmatic rules engine

### Current Work (Phase 8)
- 🚧 **Spell Validation System**: Programmatically check spell ownership before AI generation
- 🚧 **Resource Tracking**: HP, spell slots, inventory management
- 🚧 **Combat Mechanics**: Attack/damage rolls, initiative, turn tracking
- 🚧 **Rules Engine**: Intercept player actions, apply mechanics, then AI narrates

### Future Enhancements (Post-Phase 8)
- ⏳ **Subrace Support**: High Elf, Mountain Dwarf, etc. with specific abilities
- ⏳ **Advanced Filtering**: Search by CR range, spell level range, class, type
- ⏳ **Web UI**: Web interface for GM dialogue
- ⏳ **Multiplayer Support**: Multi-player sessions
- ⏳ **Custom Content Import**: User-created monsters/spells
- ⏳ **Voice Interface**: Voice commands for GM dialogue
- ⏳ **Map/Battle Grid Integration**: Visual battle maps
