watchtower is being destroyed. Removed from [vps], with its host_vars, its push
token, and the six Gatus endpoints that referenced it (liveness, disk, two
systemd services, the ntfy DNS record and the ntfy HTTP check).
ntfy went with it - it ran nowhere else - so services/ntfy is deleted,
subdomains.ntfy and ntfy_topic are gone from group_vars, and the ntfy playbook
is out of site.yml. ntfy_topic already had no readers: the three infra/4xx plays
that used it were deleted when their checks were superseded.
Two things this exposed.
services/ntfy/deploy_ntfy_playbook.yml was pointing at the WRONG MACHINE. It
said `hosts: observability`, which resolves to the host `monitoring`
(64.226.70.190) - but ntfy ran on watchtower, and ntfy.contrapeso.xyz pointed
there. Running it would have installed ntfy on the new VPS. Moot now, but it is
the same stale-identity failure as the rest: the group meant watchtower when the
play was written, and nobody revisited it when the group changed. Watchtower was
in [vps] and NO role group at all, while running caddy, ntfy and Uptime Kuma -
nothing in the repo managed any of it.
More seriously: ntfy-emergency-app on vipy (avisame.contrapeso.xyz) sends its
notifications to https://ntfy.contrapeso.xyz, topic "emergencia". Destroying
watchtower breaks it, and it is an EMERGENCY notifier - it would fail silently
at exactly the moment it matters. That is NOT resolved here, deliberately:
standing ntfy up elsewhere, pointing at ntfy.sh, or retiring the app are all
decisions, not cleanups.
What this change does is make the break impossible to miss. The URL was derived
from subdomains.ntfy, so deleting that would have turned it into an undefined
variable buried in a template. It is now an explicit ntfy_service_url in the
app's own vars, still holding the old value, with the three options written
above it. The ntfy credentials stay in the vault because that app still needs
them - the vault was restored from HEAD and only watchtower's push token
removed, rather than re-handling the plaintext.
Verified: no reference to watchtower or its IP anywhere in the repo; Gatus down
from 91 to 85 endpoints, 85 UP, 0 DOWN.

Three files existed only as second copies of things group_vars/all already
auto-loads, and 34 playbooks named them in vars_files: - which outranks
group_vars, so the copies won. The day someone edited one and not the other,
those plays would silently keep the stale value. infra_vars.yml was already
drifting: group_vars/all/main.yml had grown age_backup_recipient and
backup_pull_public_key that it lacked.
infra_vars.yml - a strict subset of group_vars/all/main.yml
infra_secrets.yml - decrypts byte-identical to group_vars/all/vault.yml
infra_secrets.yml.example - documented Uptime Kuma credentials as the reason
the file exists, which stopped being true
Deleted, along with 62 vars_files entries across 34 playbooks (12 of which
named ../../group_vars/all/main.yml directly - same defect, a vars_files entry
duplicating an auto-loaded file at higher precedence than the file itself).
Checked before touching anything: infra_secrets.yml was listed LAST in 10 plays,
after services_config.yml, so removal would flip precedence if the two shared a
key. They share none, and neither does services_config.yml with
group_vars/all/main.yml, so the removal is provably inert.
services_config.yml was the last one standing. It held four unrelated things:
caddy_sites_dir - an identical copy of roles/caddy_site/defaults/.
Deleted; the role default is now the only one.
*.tailscale_hostname (x3) - a THIRD copy of each box's identity, which
inventory.ini already holds as ansible_host.
Deleted. Edge plays now read
hostvars['<host>'].ansible_host - verified an
edge play resolves that with nothing loaded and
the other host in no play. Three copies of one
name is how bitcoin_rpc_host ended up labelled
"knots_box" while pointing at fulcrum-box.
subdomains, ntfy topic, - genuinely global: their readers span managed,
headscale namespace monitoring, vpn_control and edge, so no single
group covers them. Moved to group_vars/all/main.yml
where they auto-load. The ntfy_topic and
headscale_namespace indirection through
service_settings collapses to the global name.
the four cross-host ports - the only entries with a real justification.
Left in place; they move in the next commit.
Also dead, all Uptime Kuma residue or duplication:
phoenixd_monitor_name, forgejo_runner healthcheck_timeout_seconds/retries,
fulcrum_tailscale_hostname, and bitcoin_knots_version - the last being a
v-prefixed copy of bitcoin_knots_version_short that nothing read, two
hand-maintained copies of one version string.
Corrected a false comment: services_config.yml claimed the uptime_kuma subdomain
"no longer resolves to anything". It resolves to 164.92.239.72 and answers HTTP
302, and 11 playbooks still template it. Same wrong premise as PLAN_3.
Verification: all 37 playbooks' --list-tasks output is byte-identical before and
after. A probe resolving all 22 values services_config.yml used to supply returns
21 identical and one intended deletion (caddy_sites_dir, now role-only - confirmed
the role still resolves it: "Ensure Caddy sites-enabled directory exists" comes
back ok against the real path). memos check-diff identical before and after.
Syntax passes on every playbook.
