Sentinel Health — Offline Gemma 4 Triage for Community Health Workers

Описание: Sentinel Health is an offline-first AI triage tool powered by Gemma 4, built for community health workers in low-resource settings. Submitted to the Gemma 4 Good Hackathon (Kaggle, 2026). Runs entirely on a clinic laptop — no internet required.

Scoped to the five grassroots emergencies where minutes matter: Trauma, Poisoning, Snake Bite, MI, and Stroke. Multimodal reasoning, deterministic safety override, KB grounding, audit log, and WhatsApp escalation to the hub physician — all on a single device.

Architecture
• Multimodal Gemma 4 (gemma4:e4b-it-q4_K_M, 8B weights with sub-4B inference footprint) via Ollama — accepts symptoms + an optional ECG / wound / scene photo
• Deterministic keyword red-flag safety layer that overrides LLM triage on missed red flags
• JSON-Schema-enforced output grounded in a curated knowledge base — model picks from candidates, cannot invent
• WhatsApp wa.me deep-link handoff to the hub physician in real PHC group format, with ambulance number + ETA
• Append-only JSONL audit log with side-file image storage — record of care for the village
• Multilingual UI + voice input: English, Hindi, Tamil, Malayalam
