Koa proxy — leftmost XFF for its per-IP limits and the sign-in link's IP binding. Once traefik trusts the tunnel's fixed address (controller v0.286.0), the leftmost entry is what a
stranger writes; with the chain removed the app reads traefik's X-Real-Ip or its peer, as before — never forgeable.
Measured on 9202: a router with this middleware receives no X-Forwarded-For (felhom.eu audits/visitors-2026-10-01/A/P1).

The app half only; PostgreSQL 18 and redis 7 do not move. Bench 9401 (harness v4, swap 0): the
self-hosted workspace + a document seeded and read back before and after, 10-min watch 0 kills (anon
peak 33.5 %); the abort starts and serves. Box 9202: done in 89.2 s through the setup gate, the
document read back. Written by upgrade-test.py --write-ladder; the PG 18 step keeps its definition.

The ONLY image move in this commit. Written by upgrade-test.py --write-ladder from both venues:
- bench LXC 9401 (harness v4): converted 16 -> 18 in 26.7 s, check equal over 42 tables, the seeded
document read back, 10-minute memory watch peak 48.9 % (anon), 0 kills, 0 restarts;
- box 9202 (controller 0.283.1, the product's guarded Update, drill catalog): converted, done in
41.1 s, PG_VERSION 18, the document read back through the front door. Undo case on 9202 first:
the load failing (adminpack) -> undone in 57.5 s, back on 16, the document read back.
Target 18: Outline's official self-host compose (docs.getoutline.com, Docker) runs postgres:18 at
/var/lib/postgresql (09 decision 42's rule); Outline documents PostgreSQL 14+.

outline 1.9.1 crash-looped (15 restarts in 420s) on a fresh deploy:
SequelizeConnectionError: The server does not support SSL connections
Set the PGSSLMODE environment variable to 'disable' or enable SSL on your
database server.
The stack's own Postgres sidecar is on the app-internal network and does not
serve SSL, so the correct answer is to disable it client-side. Env var proven
wrong by the deploy.
Campaign 7 catalog sweep.

BusyBox wget (+ node/python/curl one-shots, incl mealie's socket tuple) resolve
localhost -> IPv6 ::1 with no cross-family fallback; an IPv4-only-binding app
reads docker-unhealthy while serving (vaultwarden, re-run 2026-07-06). Escalates
that instance to the class. Scoped strictly to healthcheck test: lines
(diff-reviewed: no env/config/label changed; .felhom.yml already clean). New
REUSE.md convention row.

All 51 docker-compose.yml: replaced hardcoded subdomain.${DOMAIN}
with ${SUBDOMAIN}.${DOMAIN} in Traefik labels, app env vars, and
comments.
All 51 .felhom.yml: added SUBDOMAIN deploy field (type: subdomain)
with default matching existing subdomain metadata value.
Works with felhom-controller v0.27.0 which validates and stores the
user-chosen subdomain in app.yaml. Existing deployed apps get
SUBDOMAIN auto-injected via InjectMissingFields() on next sync.
