745-line playbook becomes 37 lines (the role, plus the Caddy play for the edge
host) and a 408-line role with docker/deploy/healthcheck phases and six
templates. mempool_vars.yml is deleted; its content is the role's defaults.
Three health checks are kept, not collapsed: Mempool is three moving parts and
knowing which one is down is the point. Each has its own script, unit, timer and
push_url, driven by a mempool_healthchecks list. The Uptime Kuma specifics are
gone - the embedded Python creating monitors over the API, the /tmp credentials
file, the push-URL file read back and parsed, three Environment= rewrites - and
the three live push URLs are preserved from the vault, so reporting is unchanged.
`Enable and start health check timers` and `Display deployment status` were both
guarded by uptime_kuma_enabled despite being deployment tasks. Third service in
a row with that pattern: the deprecation banner was applied to contiguous blocks,
so anything sitting near the push plumbing was disabled with it. Ungated.
TWO OWNERSHIP PROBLEMS, different in kind:
- MINE: I wrote `owner: root` on docker-compose.yml where the original says
`owner: "{{ ansible_user }}"`. A straight violation of extract-mechanically-
change-nothing, caught only by reading the check-mode diff line by line.
Reverted to match the original.
- PRE-EXISTING, and dangerous: the playbook declared
`owner: "{{ ansible_user }}"` (1000) on the MariaDB data directory, which the
container owns as uid 999. Confirmed against `git show HEAD:` before
concluding it was not mine. It had drifted since the containers were created
and went unnoticed because the playbook had not been run since.
This was not academic. The first real run pulled a newer mariadb:10.11 and
recreated mempool-db; with the chown still in place MariaDB would have come
back to a data directory it could not write. The role now ensures the
directory exists and leaves ownership to the container. Verified after the
run: /opt/mempool/mysql is still 999:999 and all three containers are healthy.
This is a deliberate behaviour change, not part of the extraction. It is in
this commit rather than a follow-up because the faithful version was never
safe to run, so there was no intermediate state worth recording as verified.
mempool_frontend_port moved to services_config.yml: two hosts need it (this role
deploys the frontend, the Caddy play proxies to it from the edge host) and a role
default is invisible to the second play. caddy_site's parameter assert caught
this loudly - "'mempool_frontend_port' is undefined" - rather than silently.
Verified: check-mode diff clean apart from unavoidable check-mode artifacts;
first run ok=24 changed=5, zero failures; second run changed=2 - the two bare
`command:` tasks (pull, compose up) that have no changed_when and always report
changed. That is the idempotent floor. All three health checks report
ExecMainStatus 0 with their push URLs intact.

All five close-out greps return nothing: no sites-enabled handling outside
roles/, no `systemctl reload caddy`, no caddy_sites_dir self-reference, no
inline proxy unit writes. 37 playbooks syntax clean. The 14 Caddy site files
and 6 proxy units on the hosts are byte-identical to the Stage 0 baseline.
Seven play names still said "on vipy" while the play targeted a group. Renamed
to "on the edge host" - the last place a play claimed a hostname after Plan 2.
Documented the four vhosts in /etc/caddy/sites-enabled that no playbook writes
(uptime-kuma, arbretstaging, bitcoininfra, scriberr) in the caddy_site README.
None deleted.
uptime-kuma.conf was going to be deleted as dead config. It is not dead: the
louislam/uptime-kuma container is STILL RUNNING on watchtower - created
2026-02-07, restart=unless-stopped, healthy - and uptime.contrapeso.xyz returns
302, not the 502 a dead backend would give. The "decommissioning" retired the
Ansible code and the vault credentials, not the service. PLAN_3 claimed "the
tokens died with the server"; that is corrected there.
The Caddyfile.* backups are kept: one per host, Nov-Dec 2025, not churning, and
the only record of each Caddyfile before the import line was added.

lnbits is the header_up shape; memos and mempool are the Tailscale MagicDNS
shape. 108 lines removed, 25 added.
mempool was the one playbook already reloading Caddy correctly
(systemd: state: reloaded rather than command: systemctl reload caddy), so
its end marker differed - the role's handler does the same thing.
Verified:
- lnbits: full --check, site task ok, byte-identical to the live file
- memos, mempool: --check --diff via --limit edge shows exactly one added
line each, the standardised MagicDNS comment. Both playbooks fail earlier
in check mode on their VM play ("Extract memos binary", the same
download-does-not-happen-in-check-mode artifact as forgejo), but the edits
are confined to the hosts: edge play - memos at line 169+, play 2 starts
at 159; mempool at 617+, play 2 starts at 606.
The added comment means the next real run of memos/mempool rewrites one
comment line. Those two host files were already stale against their
playbooks before this change.
All 14 site files on all 3 hosts still byte-identical.

Removing the credentials would otherwise break these playbooks mid-deploy: they
template uptime_kuma_password with no assert to stop them first. 100 tasks are
now guarded by uptime_kuma_enabled (false), so deployments run normally and the
monitoring sections skip. A further 28 tasks were already self-guarding on
monitor_setup/push_url being defined; verified that a skipped task's registered
variable makes those skip cleanly rather than error.
The blocks are kept on purpose — the health-check logic is the durable part and
should be rewired to whatever replaces Uptime Kuma.
