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.

685-line playbook becomes 33 lines plus a 426-line role
(install/service/healthcheck phases, six templates, one handler).
fulcrum_vars.yml is deleted; its content is the role's defaults.
Verified: fulcrum untouched - active since 2026-07-29 (no restart), 192G datadir,
height 966842, bitcoind and db_mem unchanged on disk. Second run changed=1 (the
arming run, changed_when: false aside). vipy changed=0.
THREE PRE-EXISTING LANDMINES the check-mode diff caught, any of which a faithful
extraction would have detonated:
- bitcoin_rpc_host was "192.168.1.140", commented "IP of knots_box_local". But
.140 is fulcrum-box ITSELF; knots-box is .135. The DHCP leases had reshuffled -
the fifth instance of this same disease in this estate. The live config had
been hand-corrected to knots-box; running the playbook would have reverted it
and pointed Fulcrum at itself. Now addressed by Tailscale name.
- The `Restart fulcrum` handler was guarded by uptime_kuma_enabled, so the three
tasks that notify it (SSL cert, fulcrum.conf, systemd unit) could not restart
anything. A config change applied to disk, reported success, and silently never
took effect. That is worse than the other banner casualties: it makes the
deployment itself lie. Ungated.
- db_mem was about to go 2048 -> 4448 (75% of 5931MB RAM), leaving ~1.4GB for the
OS and Fulcrum's non-cache memory. The live value had been hand-tuned down.
fulcrum_db_mem_mb_override pins it. Note set_fact outranks role defaults, so
the calculation itself has to honour the override.
MY OWN ERROR, third instance: retyping `copy:` as `template:` lost `owner:` on
the banner and on fulcrum.conf. Rather than keep catching these by eye, every
managed path's owner/group/mode is now compared against `git show HEAD:`
mechanically - 12/12 match.
The health check timer had not fired since 2026-02-17 while reporting `active`
and `enabled`. It is OnBootSec + OnUnitActiveSec with no OnCalendar: OnBootSec
elapses once, and OnUnitActiveSec needs the SERVICE to have run this boot to have
anything to schedule from. Restarting the timer does not supply that; running the
service does, so the role now runs the check once after enabling. Also dropped
`Requires=fulcrum.service` from the timer - on a timer that means "stop watching
when the watched thing stops".
Diagnostic note: NextElapseUSecRealtime is always empty for a monotonic timer, so
it reads as broken even when healthy. I misread it once and wrongly called the
timer dead. Use NextElapseUSecMonotonic or systemctl list-timers.
fulcrum_ssl_port and fulcrum_tailscale_hostname moved to services_config.yml -
the socket-proxy play on the edge host needs them and a role default cannot reach
a second play.
