// PYRE / Prometheus Protocol — PM2 ecosystem (process manager) config.
//
// Process names match docs/PYRE_MVP_DESIGN.md §12: pyre-web, pyre-api, pyre-worker.
// Start (from repo root):  pm2 start ecosystem.config.cjs --only pyre-api,pyre-web
// Persist for boot:        pm2 save   (systemd unit infra/systemd/pm2-pyre.service
//                                      runs `pm2 resurrect` on boot)
//
// PM2 is installed at user level: ~/.local/share/pnpm/bin/pm2
// Logs go to /home/pyre/pyre/logs/ (rotated by infra/logrotate/pyre).
// Each process is capped at 400M (8GB VPS shared with postgres/redis/nginx).
//
// NOTE: api/worker run their TypeScript directly via `node --import tsx` (no
// separate build step; tsx resolves the workspace `@pyre/*` source packages).
// The web app runs Next.js in production mode and requires a prior `next build`.
