nodito: de-Uptime-Kuma the ZFS and NUT playbooks, extract templates These two are host-specific by design - nodito is a pet, not cattle - so they stay playbooks rather than becoming roles. But they had rotted. De-Kuma, following the pattern of the six service roles: Both plays opened with an assert on uptime_kuma_username/password, which were removed from the vault, so both failed before doing anything. Dropped that, the two embedded Python monitor-creation scripts, and their /tmp cleanup. Kept every check, threshold and systemd timer - those are the durable part. Reporting is now generic: `healthcheck_push_url` goes into the unit as Environment=HEALTHCHECK_PUSH_URL and the script reads ${HEALTHCHECK_PUSH_URL:-}, treating empty as normal rather than an error. The exit code is the real answer; systemd keeps it. Both scripts now also report status=down on failure instead of only going silent. Live push URLs harvested into the vault so nothing observable changes for ZFS. Three live bugs found while check-diffing: 1. 32_zfs would have DE-REGISTERED the Proxmox storage. `pvesm remove` was gated on the storage existing and `pvesm add` on it NOT existing - mutually exclusive - so a real run removed the proxmox-tank-1 entry backing every VM and never put it back. It would also have dropped `mountpoint /var/lib/vz`, which the live entry has and `pvesm add` does not set. Registration is now add-only. 2. zfs_disk_1 named ata-...WX11TN0Z, a disk no longer in the machine. The live mirror is WX120LHQ + WX11TN2P; a leg was replaced and the repo never caught up. Inert behind `when: zfs_pool_exists.rc != 0`, but wrong on any disaster-recovery run. This is the seventh instance of an identifier written down once whose hardware later moved. 3. 34_nut has NEVER been applied to nodito - no /etc/nut file carries the "Managed by Ansible" marker; they were written by hand in January 2026. The vault held the literal CHANGE_ME_TO_SECURE_PASSWORD, so applying it would have overwritten a working upsd/upsmon auth pair with a placeholder and restarted NUT, leaving the hypervisor's UPS unable to trigger a clean shutdown on mains loss. The Kuma assert was the only thing stopping that, so removing it without a replacement would have armed the gun: there is now an explicit assert that refuses to run on the placeholder. The real password is in the vault and `Configure upsd users` check-diffs clean. Templates reconciled with the live files first, so applying 34_nut is close to a no-op: added `maxretry = 3` to ups.conf and OFFDURATION / RBWARNTIME / NOCOMMWARNTIME / FINALDELAY plus quoted POWERDOWNFLAG to upsmon.conf. The only substantive additions left are the NOTIFYMSG/NOTIFYFLAG syslog lines. /usr/local/bin/ups-heartbeat.sh on the box is an orphan - mode 0644, not executable, referenced by no unit and no cron entry - but its push token belongs to a monitor that still exists and answers, so that monitor has had no heartbeat since January. Harvested as healthcheck_push_urls.ups; applying this play is what will finally feed it. Finish the host_vars migration: infra/nodito/nodito_vars.yml was byte-identical to host_vars/nodito/main.yml. Deleted it, moved nodito_secrets.yml to host_vars/nodito/vault.yml, and stripped the dead vars_files entries from all three playbooks. Extract the 13 inline `content: \|` blocks to infra/nodito/templates/, pulled via a YAML load rather than retyped. 681+582 lines become 313+344 plus templates. Ownership parity against HEAD checked mechanically: no owner/group/mode drift on any surviving task. Neither playbook has been applied. ZFS play 2 check-runs failed=0 with two changes: the script rewrite (the deployed one is a hand-edited DEBUG VERSION with `set -x`) and the Environment line.
