ntfy On Loopback, Nobody Anonymous, A Message Round-Tripped
ntfy from the upstream release (sha256-verified) as a hardened system service on loopback with a message cache, a user database and deny-all as the default access. The live test sees an anonymous publish and a wrong password refused, creates a user with ntfy's own command, publishes a message and reads it back from the topic. Original role, live-tested on Rocky Linux 10.

Documentation
ntfy
ntfy from the upstream release (sha256-verified), as a hardened system service on loopback with a message cache, a user database and no anonymous access, for a proxy that terminates TLS. Original role for EL 10, live-tested with podman on Rocky Linux 10.
No package, so the checksum is the whole story. EL 10 carries no
ntfy; ntfy ships a release with a checksum file beside it. The
role downloads both and has Ansible's get_url refuse the asset unless its
SHA-256 is the one in the vendor's file, then installs the binaries as
root's in /usr/local/bin, pinned by ntfy_version.
A service account, a hardened unit, a loopback listener. ntfy
is a system user with no shell that owns the data directory and nothing
else; the unit runs with NoNewPrivileges, PrivateTmp, ProtectHome and
ProtectSystem=strict. The listener is 127.0.0.1:2586 by default,
for a proxy that authenticates or a client on the same host; the live test
reads the listening sockets and expects loopback only.
Nobody is anonymous. auth-default-access is deny-all, so a
topic is published to and read by accounts only: ntfy user add creates
them and ntfy access grants topics. The live test proves the setting
both ways: an anonymous publish is 403 and a wrong password 401 before a
message is published with a real account and read back from the topic
through /<topic>/json?poll=1, which is the cache doing its work.
The user database is the service's. ntfy user writes user.db
directly, so the live test runs it as the ntfy user; a database created
by root would be one the server cannot write. Signup is off and login on:
accounts are made on the host, not on the web page.

ansible-kafka
Apache Kafka 4 (SHA-512 pinned) on Java 21, one KRaft node on EL 10 from the upstream release, as a hardened systemd service on loopback; the live test creates a topic, produces one message, consumes it back and reads the metadata quorum; the metadata log is formatted once as the service user and the root-owned release tree is run in place. Original role, live-tested on Rocky Linux 10.
ansible-dovecot
Dovecot from AppStream: IMAP for your mail clients and LMTP for your MTA, Maildir in each home, TLS required before any login, a minimum TLS version checked before it lands, and every listener on loopback until you open it. The live test delivers over LMTP, reads the message over IMAPS, and sees a plaintext login from another address refused. Original role, live-tested on Rocky Linux 10.
ansible-gotify
Gotify on EL 10 from the vendor's release, pinned by a SHA-256 the role carries (the vendor publishes no checksum file), as a hardened systemd service on loopback with its settings in an EnvironmentFile; the live test creates an application, pushes a message with its token, reads it back as the admin, and sees a wrong password and a bad token refused. Original role, live-tested on Rocky Linux 10.
ansible-postfix-tls
An EL host opens no submission service, so every client sends on port 25 where plaintext is accepted. This role adds 587, which refuses mail until the session is encrypted, and 465, which is TLS from the first byte. Port 25 keeps taking plaintext on purpose and the live test asserts it, because a mail exchanger that demands STARTTLS loses mail. Original role, live-tested on Rocky Linux 10.
ansible-mosquitto-broker
Mosquitto (MQTT) with accounts: the package starts in local-only mode with anonymous clients allowed, no persistence directory and no packet-size limit. This role writes a listener that refuses anonymous and wrong-password clients (proved live), keeps retained messages across restarts, caps packets at 1 MiB, and renders topic ACLs from a list. Original role, live-tested on Rocky Linux 10.
ansible-nats
nats on EL 10 from the GitHub release; get_url refuses it unless its SHA-256 is in the vendor's checksums file, and the live test re-checks it, then saves a context under a throwaway config home, reads it back, and runs server check connection against a dead port expecting exit 2 and CRITICAL. Pinned. Original role, live-tested on Rocky Linux 10.
