Data Flow Explained
FLOW 01
Student SMS Enrollment
Student texts JOIN CS101 XK9P2M → Twilio receives it → fires webhook to Render backend → backend validates join code against Neon DB → enrolls student → Twilio sends confirmation back to student's phone
FLOW 02
Staff Dashboard Alert
Staff logs into app.paws-alert.com (Render frontend) → selects section + message → React calls Render backend API → backend queries Neon for recipients → loops through Twilio to send SMS to every enrolled student → logs delivery receipts back to Neon
FLOW 03
Staff SMS Interaction
Staff texts any message → Twilio webhook → backend checks if number is registered staff in Neon → if yes, Claude API guides conversation → staff picks section + priority + message → backend fires broadcast via Twilio → result texted back to staff
FLOW 04
Deploy Pipeline
Code pushed to GitHub → Render auto-detects push → builds and deploys backend (FastAPI) and frontend (React/Vite) → Netlify auto-deploys consent page from its own GitHub repo → live within ~2 minutes
FLOW 05
DNS Resolution
paws-alert.com bought on Namecheap → nameservers pointed to Netlify → Netlify manages all DNS records → paws-alert.com serves consent page → app.paws-alert.com CNAME points to Render frontend → api subdomain points to Render backend
FLOW 06
Scheduled Alerts
Staff schedules alert via dashboard → stored in Neon with UTC timestamp → APScheduler on Render backend checks every 60 seconds → when time is due fires broadcast via Twilio → updates status in Neon → logs delivery receipts
