v0.2.0 — EC2 Pilot

v0.2.0 — EC2 Pilot: Frontend + Backend + Infra + Legal

Highlights

• ✅ Live pilot on AWS EC2 (Amazon Linux 2023, t2.micro) behind Nginx (HTTP→HTTPS), self-signed TLS.
• ✅ RAG online: Pinecone (1024-dim) + Bedrock Titan (embed + text).
• ✅ Unified build: React UI uses relative /api/* paths; same bundle works locally and on EC2.
• ✅ Systemd service for FastAPI/Uvicorn on 127.0.0.1:8000.

What’s New

• Frontend: Chat UI send arrow, dark mode, Vite proxy, static build.
• Backend: FastAPI endpoints (/api/chat/, /api/status, /health) and RAG wiring.
• Nginx: Static /, proxy /api/ → 127.0.0.1:8000, /health → backend.
• Infra (pilot): EC2 setup scripts, nginx config, self-signed cert bootstrap.
• Legal/Security: LICENSE, NOTICE, COPYRIGHT, TRADEMARKS.md, SECURITY.md,
  THIRD_PARTY_BACKEND.md, THIRD_PARTY_FRONTEND.json.
• Repo hygiene: modern .gitignore, updated README.

Known Risks (pilot)

Self-signed TLS warning; no auth; single instance; manual deploy; limited corpus.

Upgrade Notes

1. Pull latest main.
2. Build UI: cd frontend && npm ci && npm run build.
3. scp dist.tgz to EC2.
4. Unpack to /var/www/nexusai, reload nginx; ensure privategpt-backend.service is active.
