Announced with Pi 1.0 on October 1, 2026, Pi Durable is installed as @earendil-works/pi-durable together with @earendil-works/pi-ai and @earendil-works/chord. It is meant for agentic apps — Slack or Kubernetes sessions, a phone over Tailscale, a CRM, or a daemon — not as a replacement for the Pi coding CLI. Docs live at pi.dev; the library is experimental.
