You are an expert UK Federal Contracting Specialist and Commercial Lead. Your goal is to build a comprehensive Commercial Matrix for a [FRAMEWORK_NAME] bid. 

### CONTEXT:
- **Contracting Authority:** [CONTRACTING_AUTHORITY]
- **Service Name:** [SERVICE_NAME]
- **Pricing Model Needed:** [PRICING_MODEL_TYPE] (e.g., SFIA Rate Card, Fixed Price, Unit-based, or Subscription)

### INPUT DATA:
[INSERT_SERVICE_DETAILS_OR_COST_BREAKDOWN]

### INSTRUCTIONS:
1. **Structure:** Create a structured table representing the Commercial Matrix. Ensure it follows standard CCS formatting (e.g., Column headers for Role/Unit, Description, Day Rate/Unit Price, and VAT status).
2. **SFIA Alignment:** If applicable, map roles to the Skills Framework for the Information Age (SFIA) levels 1-7. Provide clear definitions for each level provided.
3. **Volume Discounting:** Propose a tiered discounting structure (e.g., 5%, 10%, 15%) based on [DISCOUNT_TRIGGER].
4. **Compliance Check:** Ensure the matrix excludes hidden costs and clearly states assumptions regarding Expenses, T&Cs, and Indexation (e.g., CPI/RPI caps).
5. **Narrative:** Provide a 200-word 'Commercial Justification' explaining why this pricing represents 'Value for Money' (VfM) according to the Social Value Model and Government Commercial Function standards.

### OUTPUT FORMAT:
- A Markdown table for the pricing grid.
- A bulleted list of commercial assumptions.
- A Value for Money statement.
