jarld also listens on /run/jarl/jarl.sock (socket in jarl.yaml). Requests
on it from root or jarld's own user need no token and act as an
administrator; the kernel's SO_PEERCRED says who is connecting, and
anyone else must send a token. The jarl CLI uses the socket when no server
is configured, or with -s local, so 'sudo jarl status' works on the server
with nothing set up and a lost token or password never locks root out.
Changes are audited under the system user's name via "socket".
The systemd unit creates /run/jarl (0750). Socket paths over 107 bytes
are refused with a clear message. The docs explain the socket and what
happens when a token is revoked.

Jarl keeps a BIND 9.20 server's whole configuration (views, ACLs, TSIG
keys, zones of every type, records, named.conf options) in SQLite and
renders named.conf, keys.conf and zone files from it.
Every change goes through one changeset pipeline: whole-configuration
validation, named-checkconf -z and named-checkzone in a staging
directory, atomic install, rndc reconfig/reload, serial verification
with rndc zonestatus, and rollback if named does not load the change.
Changes apply one at a time by default or are bundled and applied
together. Applied changesets can be reverted.
- jarld: the daemon with the REST API and an embedded web UI, plus import,
adopt, check, resync, backup and local user recovery commands
- jarl: the CLI, including ACME DNS-01 hooks for certbot and acme.sh
- users with argon2id passwords and CSRF-protected sessions; hashed API
tokens with granular grants and roles; an audit log
- systemd unit, sysusers.d/tmpfiles.d files, Makefile
- unit tests, integration tests against a real named, scripts/e2e.sh
- docs/ guides, README and CHANGELOG
