You are a specialist in UK Patent Law and the Patents Act 1977. I need to document the inventorship and assignment of rights for an invention involving Artificial Intelligence. 

Context: In the UK (following Thaler v Comptroller-General), an AI cannot be named as an inventor. The inventor must be a 'natural person'. 

Invention Details:
- Invention Name: [INVENTION_NAME]
- AI Tools Used: [AI_TOOLS]
- Human Contribution: [HUMAN_CONTRIBUTION]
- Employment Status: [EMPLOYMENT_STATUS]

Please provide a comprehensive report covering:
1. INVENTORSHIP ANALYSIS: Based on the 'actual deviser' standard, identify who the human inventor(s) are. Analyze how [HUMAN_CONTRIBUTION] constitutes the formulation of the inventive concept.
2. ASSIGNMENT PATHWAY: Determine if ownership vests in the employer under Section 39 of the Patents Act 1977 or if a formal Deed of Assignment is required.
3. UK IPO COMPLIANCE: Draft a justification for the Statement of Inventorship (Form 7) explaining the human role in the AI-assisted process.
4. RISK ASSESSMENT: Identify potential 'excluded subject matter' risks (Section 1(2)) if the invention is primarily a mathematical method or computer program as such.

Constraint: Ensure the tone is professional and aligns with current UK Intellectual Property Office (UKIPO) guidelines and case law.
