feat: Phase 5 - Real-Time Result Transmission & Transparency Platform

Phase 5 – Real-Time Result Transmission & Transparency Platform

Summary

Adds 6 features to the existing INEC Election Platform, introducing 3 new frontend pages, new Go backend endpoints, and a rewritten Python analytics service for AI-powered anomaly detection.

Features added:

1. PWA – Service worker (sw.js) + manifest for offline viewing; network-first for navigation, cache-then-network for assets.
2. SMS/USSD Gateway – Go endpoints (/sms/verify, /ussd/gateway, /sms/stats) for mobile result verification without internet. USSD supports a multi-step session menu.
3. AI Anomaly Detection (Python) – Benford's Law (first & last digit), z-score/IQR turnout outliers, overvoting, party dominance (>90%), round-number bias, sequential/identical pattern detection. Composite integrity score (0–100, A–F grade).
4. Multi-language – Expanded i18n (EN, HA, YO, IG) across all pages via useI18n hook and language selector in header.
5. Accessibility – WCAG AA improvements: aria labels, skip link, keyboard-focusable landmarks, aria-live status regions, role attributes on tables/groups.
6. Public API v1 – Versioned endpoints (/api/v1/*) with API key auth (X-API-Key header), in-memory rate limiting (100 req/min), and OpenAPI 3.0 spec at /api/v1/docs.

New files:

• inec-go-backend/sms_ussd.go, public_api.go, ai_proxy.go
• inec-frontend/src/pages/AnomalyDetectionPage.tsx, SMSVerificationPage.tsx, PublicAPIPage.tsx
• inec-frontend/public/sw.js, manifest.json, icons/
• inec-backend/app/analytics.py

Review & Testing Checklist for Human

• SQL schema alignment: Verify result_votes vs result_party_scores table name usage is consistent with actual DB schema (queries in public_api.go lines 89–290 and analytics/main.py party_performance)
• USSD hardcoded election_id=1: sms_ussd.go lines 195, 199, 204 hardcode election ID 1 for USSD flows – confirm this is acceptable or needs parameterization
• API key security: Public API keys are SHA256-hashed but stored in SQLite with no expiry/rotation – review if acceptable for production
• Rate limiting resets on restart: In-memory rate limiter in public_api.go – verify this is acceptable or needs Redis/persistent store
• Test AI anomaly detection end-to-end: Navigate to AI Anomaly page, verify integrity score loads, Benford chart renders, anomaly list populates

Recommended test plan:

1. Open https://inec-election-platform-app-8t3vto5u.devinapps.com
2. Navigate to AI Anomaly, SMS/USSD, and Public API pages – verify no console errors
3. Test SMS verification: enter phone + PU code, submit
4. Test Public API: generate an API key, copy it, test curl -H "X-API-Key: <key>" https://app-pugfnumm.fly.dev/api/v1/elections
5. Test language switcher (EN→HA→YO→IG) on any page
6. Test PWA: open DevTools → Application → Service Workers, verify inec-v6 is active
