// PYRE / Prometheus Protocol — PM2 ecosystem (process manager) config
//
// ⚠️  INERT / NOT YET RUNNABLE: the apps are NOT implemented yet. This file
//     defines how the three PYRE processes WILL run once apps/web, apps/api,
//     and apps/worker are built/deployed. Starting it now will fail because
//     the apps (and their builds) do not exist yet.
//
// Process names match docs/PYRE_MVP_DESIGN.md §12: pyre-web, pyre-api, pyre-worker.
//
// Once apps exist, start with:
//   pm2 start ecosystem.config.cjs
//   pm2 save            # persist process list so `pm2 resurrect` works 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).
//
// Note on memory: the 8GB VPS is shared with postgres, redis, nginx, etc.,
// so each process is capped at 400M via max_memory_restart.
