Comprehensive refactoring plan targeting the Hetzner CAX21 (ARM64/Debian/8GB) environment. Covers 17 items across P0–P3 priority levels: - P0: ARM64 platform declaration, graceful shutdown, Redis persistence, log rotation, systemd auto-start - P1: Swap config, per-service memory limits, seed retry with backoff, ufw firewall, cron seeding - P2: Structured JSON logging, health check automation, Docker Secrets - P3: TLS via Cloudflare Proxy https://claude.ai/code/session_012cgux13dymqPbJMuJoWBWs
Revise VPS_REFACTORING_PLAN.md to include Gemini-powered Discord
periodic notification as a P1 item (Section 7):
- New script: scripts/discord-notify.mjs
- Fetches 8 data categories from Redis in parallel
(earthquakes M5+, unrest HIGH, military flights HIGH,
natural disasters, weather EXTREME/SEVERE, cyber CRITICAL,
armed conflict, market movers ±2%)
- Summarizes via Gemini 2.0 Flash (direct API) with
OpenRouter fallback (google/gemini-2.5-flash)
- Posts rich Discord Embed with color-coded threat level
- Supports configurable interval via DISCORD_NOTIFY_INTERVAL_MINUTES
- Runs as one-shot (cron) or daemon (--daemon flag)
- New env vars: DISCORD_WEBHOOK_URL, GEMINI_API_KEY,
GEMINI_MODEL, DISCORD_NOTIFY_INTERVAL_MINUTES, DISCORD_NOTIFY_LANGUAGE
- Added to Week 2 roadmap alongside other P1 items
- Updated file list and status summary tables

…ation P0 — Production-critical: - docker-compose.yml: add linux/arm64 platform to all build sections - docker-compose.yml: enable Redis AOF+RDB persistence, maxmemory 1GB - docker-compose.yml: add per-service mem_limit (2g/3g/1.2g/256m) - docker-compose.yml: add json-file log rotation (max-size/max-file) - local-api-server.mjs: add createLogger() for structured JSON logging in Docker mode; plain console in desktop/sidecar mode - local-api-server.mjs: add SIGTERM/SIGINT graceful shutdown with 30-second force-exit safety net P1 — Operational stability + Discord notifications: - docker-compose.yml: add DISCORD_WEBHOOK_URL / GEMINI_API_KEY / GEMINI_MODEL / DISCORD_NOTIFY_INTERVAL_MINUTES / DISCORD_NOTIFY_LANGUAGE env vars; add OPENROUTER_API_KEY passthrough - scripts/discord-notify.mjs (new): Redis → Gemini → Discord pipeline - Fetches 8 data categories in parallel from Redis - Filters for notable events (M5+ quakes, HIGH unrest, CRITICAL cyber, etc.) - Summarises with Gemini 2.0 Flash (direct API) or OpenRouter fallback - Posts rich colour-coded Discord Embed with per-category fields - One-shot mode (cron) or --daemon mode (supervisord) - Exits 0 when env vars unset so supervisord does not restart - scripts/run-seeders.sh: replace single-attempt loop with run_with_retry() (3 attempts, exponential backoff 1s/4s) - docker/supervisord.conf: add discord-notify program (autorestart=unexpected) - scripts/setup-vps.sh (new): one-shot VPS bootstrap script (2GB swap, Docker install, ufw firewall, systemd service, cron jobs) - docker/worldmonitor.service (new): systemd unit template with __REPO_DIR__ placeholder substituted by setup-vps.sh P2 — Monitoring: - scripts/health-check.sh (new): polls /api/health every 2 min, sends Discord alert and optional email on DEGRADED/UNHEALTHY/UNREACHABLE Misc: - .env.example: document DISCORD_WEBHOOK_URL, GEMINI_API_KEY, GEMINI_MODEL, DISCORD_NOTIFY_INTERVAL_MINUTES, DISCORD_NOTIFY_LANGUAGE https://claude.ai/code/session_012cgux13dymqPbJMuJoWBWs

Summary
Comprehensive refactoring plan and implementation for 24/7 stable operation on Hetzner CAX21 (ARM64 Debian). Adds critical production-readiness features: ARM64 Docker builds, graceful shutdown, Redis persistence, automated service startup, Docker log rotation, and a new Discord notification system powered by Gemini AI.
