Develop LLM-based Certification Verification

Using Google Gemini 2.5 Pro (or a suitable alternative), develop a module that takes unstructured text from a simulated material certification document as input. The LLM should extract key information such as the material name, its embodied carbon value, claimed carbon reductions, and compliance with specified standards (e.g., ASTM). The module should also attempt to 'verify' these claims by comparing them against a small, curated internal knowledge base of known industry averages or standards, assigning a confidence score.
