## Process Workflow

### Step 0: Content Safety Validation (MANDATORY)

**CRITICAL**: This check runs BEFORE any content generation.

1. **Input Validation**: Verify style, character, age are in allowed lists
2. **Forbidden Content**: Reject violence, horror, adult, political, commercial content
3. **Age-Theme Check**: Ensure theme appropriate for age group

> **Full rules**: `references/config/core/content-safety-validation.md`

### Step 0.5: Pre-Generation Helpers (Optional)

**Style Assistant** (`help:style [mood]`): Get style recommendations based on desired feeling
**Character Advisor** (`help:character [context]`): Get character recommendations based on story context
**Character Type Detection**: Auto-detects animal vs human character requests

> **Full details**: `references/config/core/style-assistant.md`, `references/config/core/character-advisor.md`

### Step 1: Parameter Validation

Validate style, scene, and age/pages parameters. If missing, ask user to specify.

**Age-Driven Auto-Calculation**:
- Ages 3-4: 1-3 pages, basic cognition
- Ages 5-6: 3-5 pages, basic science + social skills
- Ages 7-8: 5-7 pages, science + math + history
- Ages 9-10: 7-10 pages, advanced science + psychology
- Ages 11-12: 10-15 pages, interdisciplinary learning

> **Full specifications**: `references/config/core/age-system.md`

### Step 2: Character Consistency (CCLP 4.0)

Apply **Character Consistency Lock Protocol v4.0** for multi-page stories.

**Three Flexibility Levels**:
1. **STRICT** (Default): 100% identical appearance across all pages
2. **MODERATE**: Fixed face/hair/body, scene-adaptive clothing with narrative justification
3. **FLEXIBLE**: Signature features only, time/theme-adaptive changes

**Core Requirements**:
- **MANDATORY SIGNATURE markers** on key features
- **LOCK ESTABLISHED** statement on Page 1
- **CONSISTENCY REFERENCE** statement on subsequent pages
- **Watermark Prevention Level 2 (35 words)** at prompt end
- **Prompt compression**: 280-300 words total

> **Full protocol**: `references/config/cclp/character-consistency-lock.md`, `references/config/cclp/CCLP-FLEXIBILITY.md`

### Step 3: Content Generation

#### For Single Page
Generate four components:
1. **Story Text**: Bilingual (Chinese first, English), age-appropriate
2. **Learning Focus**: Chinese character + learning domain for age
3. **Image Prompt**: Character anchor + scene + style + rendering + watermark prevention
4. **Formatted Output**: Standard template

#### For Multi-Page Stories
1. **Cover Page**: Character showcase, title space, inviting atmosphere
2. **Story Arc**: 3-page (B-M-E), 5-page (full arc), 7-page (extended journey)
3. **Narrative Continuity**: Character consistency, story flow, learning progression
4. **Story Summary**: Characters learned, theme, extension activities

> **Story patterns**: `references/config/core/story-flow.md`
> **Output format**: `assets/templates/output-format.md`

### Step 4: Pre-Output Validation

**Reality Validation** (for discovery/science themes):
- Cross-check scene Observable Elements
- Verify biological/physical accuracy
- Scan for common error patterns

> **Validation rules**: `references/config/advanced/reality-validation.md`

### Step 5: File Output

Save to: `./output/picture-books/[YYYY-MM]/[style]-[scene]-[character]-[pages]-[timestamp].md`

## Image Prompt Assembly

### Solo Character Format
```
[Style] children's picture book illustration,
[Character Anchor with expression],
[Action/Pose],
[Scene Elements],
[Style Keywords],
[Rendering Parameters],
[Watermark Prevention Level 2]
```

### Multi-Character Format
```
[Primary Character Anchor - 150 words],
[Primary Action + Interaction],
[Secondary Character - 40-50 words],
[Relationship Description],
[Scene + Style + Rendering],
[Watermark Prevention Level 2]
```

**CRITICAL Multi-Character Rule**: NEVER use generic descriptions ("family members", "Dad's silhouette"). Each visible character MUST have detailed visual anchor.

> **Supporting character anchors**: `references/config/advanced/supporting-characters.md`
> **Multi-character fix guide**: `references/guides/MULTI-CHARACTER-PROMPT-FIX.md`

### Watermark Prevention (MANDATORY)

**Level 2 (35 words - Default for multi-page)**:
```
clean professional children's book illustration, publication-ready quality, pristine unmarked image, full bleed composition, no watermark, no text overlays, no signatures, no artist marks, no logos, no branding, no copyright symbols, no website URLs, clean professional image
```

**Placement**: MUST be LAST in prompt.

> **Troubleshooting**: `references/guides/WATERMARK-TROUBLESHOOTING.md`
