Standalone ESM-daemon that:
- Connects via ImapFlow IDLE to all active Legend mailboxes
- Triggers /api/mail/scan-internal on new-mail events (real-time)
- Auto-renew IDLE every 25min (RFC 3501 limit), exponential-backoff reconnect
- DB-refresh every 5min for new/removed connections
Plus deploy-pipeline:
- GH-Actions artifact-upload + scp to /srv/rebreak/backend/imap-idle/
- npm install --production on server (imapflow + pg)
- pm2 startOrReload via ecosystem.config.js
- start-idle-staging.sh wrapper for Infisical secret-injection
