MandiShield is an open-source multimodal agro-chemical and seed forensic inspection engine powered by Google Gemma 4 (gemma-4-26b-a4b-it & local edge Ollama), safeguarding India’s 140 million smallholder farmers against the ₹25,000 Cr counterfeit agricultural input crisis.

Key Capabilities:

1. Real Laboratory & Raid Test Cases: Pre-loaded with authentic high-resolution forensic photos—including an enforcement raid seizure of illicit warehouse containers (Case 1) and laboratory tray seed morphology with cracked dyed grains (Case 1).
2. Autonomous Vision Forensics: Scrutinizes bottle packaging, micro-typography, dot-matrix vs flat-print batch numbers, and Rule 19 toxicity diamonds (Red/Yellow/Blue/Green) against oral LD50 values under the Insecticides Act 1968.
3. Seed Coating & Purity Morphological Inspection: Evaluates fungicide coating uniformity (pink Thiram/Captan) vs illegal food dyes, inert matter/chaff %, and non-viable embryos under Seeds Act 1966.
