tarla.io notification generator - updated production workflow & architecture

🚀 System Overview

Complete production workflow for the AI-powered agricultural notification generator integrated with Tarla.io's GraphQL API. This system generates personalized farming advice using Google Gemini AI, weather data, and crop intelligence.

🆕 Major New Features (Latest Update)

✅ Production GraphQL Integration

• Real Farmer Data: Now fetches actual farmer data from production database instead of local JSON files

• Service Account Authentication: Uses JWT service account tokens to access the API

• Push Notification Delivery: Can send real notifications to farmers via pushService mutation

• Dual Mode Operation: TEST mode sends to Slack for review, PRODUCTION mode sends actual notifications
