One binary and one SQLite file. Topics with ntfy-style publish and subscribe, HTTP/TCP/DNS/TLS/heartbeat monitors with a public status page, schedules and escalation policies, and incidents with a timeline and post-mortem. The UI follows the Lightwell design language. Builds against an unreleased Reef (secretbox) through a local replace line. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
