## 🎯 Training Dataset Design

**54 images across 8 visual categories:**

1. **Estate Interiors** (10) — Barakat estate, baroque + phoenician, decay
2. **Church and Ritual** (8) — Maronite Catholic, communion, reverence  
3. **Nightclub and Violence** (8) — Opulence with basement, hidden danger
4. **Lebanon and Memory** (8) — Byblos, civil war, cemetery, exile
5. **Family and Food** (6) — Communion reception, gatherings, tension
6. **Character Portraits** (10) — Fredric, Magda, Billy, Vincent, Aida
7. **Symbolic Objects** (8) — Crucifix, gold Beretta, bread and blood
8. **Title Cards** (6) — Deck visuals, typography, dividers

**All captions use:**
- Trigger word: `the baker film style`
- Style keywords: `grandeur with decay`, `chiaroscuro lighting`, `cinematic`, etc.

---

## 🚀 Execution Workflow

### Step 1: Setup Environment (5-10 min)
```bash
cd /home/workspaces/thebaker/training
./01_setup.sh
```

**What it does:**
- Finds available Python (nix store or creates local venv)
- Checks GPU (RTX 6000 Ada detected ✓)
- Installs PyTorch, diffusers, transformers, accelerate, peft
- Validates CUDA availability

---

### Step 2: Generate Dataset (30-60 min)
```bash
python generate_dataset.py --config config.json
```

**Output:**
- `dataset/images/` — 54 PNG files (1024x1024)
- `dataset/captions/` — 54 TXT caption files

**Requirements:**
- GPU with 24GB+ VRAM (your RTX 6000 Ada has 48GB ✓)
- ~25 GB disk space for base Flux.2 model download

---

### Step 3: Train LoRA (2-4 hours)
```bash
python train_flux_lora.py --config config.json
```

**Configuration:**
- Rank: 16 (balanced style capture)
- Steps: 2000
- Batch size: 1
- Mixed precision: fp16
- Checkpoints: Every 500 steps

**Output:**
- `outputs/lora_weights.safetensors` (~100-200 MB)
- Training checkpoints
- TensorBoard logs

---

### Step 4: Generate Deck Visuals (15-30 min)
```bash
python generate_deck_visual.py --batch --lora outputs/lora_weights.safetensors
```

**Output:**
- 13 deck visuals in `assets/decks/visuals/`
- Ready for Typst deck integration

---

## 🎨 Visual Style Captured

**Core Aesthetic:**
- **Grandeur with decay** — Beauty and rot in same frame
- **Chiaroscuro lighting** — Moral pressure through light
- **Baroque Catholic weight** — Ornate, ceremonial
- **Phoenician memory** — Lebanese heritage elements
- **Cinematic composition** — Pitch-ready quality

**Example Prompt:**
```
the baker film style, fredric barakat portrait, aging patriarch, 
grandeur with decay, chiaroscuro lighting, cinematic
```

## 📦 Deliverables

### After Training:
- ✅ Reusable LoRA model (`lora_weights.safetensors`)
- ✅ Training checkpoints for rollback
- ✅ Training metrics and logs

### After Generation:
- ✅ 13 deck visuals (16:9 format, 1024x576)
- ✅ Ready for Typst integration
- ✅ Reusable for marketing materials

### Long-term Value:
- ✅ Infinite deck visual generation
- ✅ Consistent brand aesthetic
- ✅ Fast iteration for updates
- ✅ Marketing asset library

---

## 🔧 Integration with Typst Deck

### Option A: Direct Image Insertion
```typst
#image("../training/assets/decks/visuals/02_the_bargain.png", 
       width: 100%, fit: "cover")
```

### Option B: Visual Reference Cards
```typst
#visual_card[
  #image("assets/decks/visuals/09_communion.png", width: 100%)
  #note[Holy Communion — immersive family realism]
]
```

### Option C: Background Textures
```bash
python generate_deck_visual.py \
  --prompt "the baker film style, deep black background, subtle texture" \
  --output background.png \
  --lora outputs/lora_weights.safetensors
```

## ✅ Quality Assurance

### Dataset Review Checklist:
- [ ] All 54 images generated
- [ ] No artifacts or distortions
- [ ] Chiaroscuro lighting visible
- [ ] "Grandeur with decay" aesthetic present
- [ ] Captions match images

### Training Review Checklist:
- [ ] Loss decreases steadily (< 0.1 by step 2000)
- [ ] No NaN/Inf errors
- [ ] Checkpoints saved successfully
- [ ] LoRA file size < 200MB

### Output Review Checklist:
- [ ] All 13 deck visuals generated
- [ ] Images match slide content
- [ ] Style consistent across images
- [ ] Resolution appropriate for deck

---

## 🛠️ Troubleshooting

### Out of Memory
```json
{
  "training": {
    "rank": 8,
    "batch_size": 1,
    "gradient_accumulation_steps": 8
  }
}
```

### Poor Quality
- Increase training steps to 3000
- Increase rank to 32
- Refine dataset captions
- Add more training images

### Environment Issues
```bash
./01_setup.sh  # Re-run setup
```

---

## 📈 Next Steps

### Immediate (Today):
1. ✅ Run `./01_setup.sh` to prepare environment
2. ⏳ Run `./00_quickstart.sh` (option 4: Full pipeline)
3. ⏳ Monitor training progress (2-4 hours)
4. ⏳ Review generated deck visuals
5. ⏳ Integrate with Typst deck

### Short-term (This Week):
- Generate additional marketing assets
- Create character lookbook
- Test with Ronny/Nicholas for creative validation

### Long-term:
- Use LoRA for social media tiles
- Generate press kit imagery
- Create investor presentation visuals
- Build cast/crew lookbook

- Documentation (7 guides)
- Environment setup automation

**⏳ PENDING EXECUTION:**
- Environment setup (`./01_setup.sh`)
- Dataset generation
- LoRA training
- Deck visual generation
- Typst deck integration

---

## 🚀 Ready to Execute

**Start command:**
```bash
cd /home/workspaces/thebaker/training
./01_setup.sh
```
