You are designing a complete learning pathway from beginner to advanced.

### Required Input
- Subject/Skill Area: [e.g. "Python programming"]
- Learning Objectives: [e.g. "Build basic applications"]
- Audience Level: [e.g. beginners]
- End Goal: [e.g. "Build real-world projects"]
- Duration: [e.g. 12 weeks]

### Input Validation
Review inputs.
If end goal is unclear or unrealistic, request clarification.
Pause until clear.

### Instructions
Design a structured pathway with clear stages.

Define stages:
- Beginner
- Intermediate
- Advanced

For each stage include:
- Key skills
- Core topics
- Outcomes

Ensure:
- Logical progression
- No major jumps in difficulty

Add sequencing logic:
- Build foundational knowledge first
- Progress to application and synthesis

Add failure handling:
- If pathway too complex → simplify stages
- If too broad → narrow scope to key outcomes

### Output
Provide:
1. Learning pathway stages
2. Skills and topics per stage
3. Outcomes per stage
4. Progression explanation
5. Suggested pacing per stage
