detect_node_ip recomputed FELIS_ROOT_DOMAIN from scratch on every run and fell back to <node-ip>.nip.io. Nothing read the domain back out of the felis.toml an earlier run wrote, so it survived only as long as the operator kept passing the same environment. That made re-running the installer destructive on any install with a real domain, and re-running it is not optional: it is the only way to move felis-api to a newer release, which is what `felis update` points operators at. A bare re-run rewrote root_domain, panel_hostname and admin_hostname to nip.io names while ensure_panel_tls_cert returned early on the certificate it had already written, leaving the console serving a cert for hostnames it no longer answered to -- with no re-domain flow to recover through. Precedence is now explicit FELIS_ROOT_DOMAIN, then the domain the last run persisted, then the nip.io default. First installs are unaffected. Deliberate re-domains still work, because there is no other route to one, but they now warn that the write-once certificate is not reissued and that the proxy and login config carry the old name too. Secrets were never exposed to this: load_or_make_secrets has always sourced secrets.env before generating anything. The domain was the one piece of install identity with no read-back. The channel is deliberately left alone. FELIS_VERSION_BOOTSTRAP is not persisted either, but defaulting a re-run to the release channel installs a working build rather than breaking one, so cmd/felis/update.go states that instead. Its warning about the domain went with the bug and would now be false. Verified against the shipped function text: the ladder holds for a fresh host, a re-run with and without the variable set, a re-domain, and a felis.toml whose root_domain is missing or empty. Reverting the one line reproduces the nip.io overwrite.

Table of Contents
Features
- Wake on Join: Servers start automatically when a player connects, and stop when idle — like hibernate for your server.
- Web Dashboard: Monitor server status, online players, and resource usage from your browser, with backup and restore management.
- Auto Backup & Restore: Scheduled world backups with one-click rollback from any backup point.
- World Reaper: Worlds idle for more than 15 days are automatically backed up and removed to free disk space.
- Multi-core Support: Compatible with Paper, Fabric, Forge, and NeoForge, federated behind a Velocity proxy.
- Modpack Submission: Players submit custom modpacks; admin approval triggers automatic build and deployment.
- Passkey Login: Passwordless authentication via fingerprint, face recognition, or hardware security keys.
- Zero Trust Security: Panel traffic protected by Cloudflare Access; the internal API is never exposed to the internet.
Getting Started
On a prepared Linux host, run:
curl -fsSL https://raw.githubusercontent.com/MliroLirrorsIngenuity/Felis/main/deploy/bootstrap.sh | sudo bash
The script installs K3s, deploys the control plane, and launches a setup wizard. Once done, open your browser at the configured domain.
