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.
