django-allauth 0.63.3 — leftmost XFF for its per-IP login limits. 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).

Written by upgrade-test.py --write-ladder: bench (harness v4) healthy in 217 s, the world-data file present and reused ("Latest data already imported"), 6 migration lines, seed read back, memory watch anon peak 73.0 %, 0 restarts; box 9202 through the guarded Update in 204 s with the product's default 5-min wait (a first try under the drill's 90 s wait was UNDONE correctly). Same commit: (1) the frontend healthcheck override is dropped — v0.13.0 brings its own (node at /usr/bin/node); (2) a world-data file that does not parse to its end is renamed aside before start so download-countries fetches it again — with an import pending, the image's own start crash-looped 10 times on IncompleteJSONError, with the step it was set aside, downloaded and healthy.

The frontend healthcheck ran 'wget --spider', but the image is distroless: no
shell, no wget, no curl, and node itself is only reachable at an absolute path
(/nodejs/bin/node, off PATH). The probe therefore ENOENT'd on every run, the
container stayed permanently unhealthy, and Traefik -- which will not route to
an unhealthy container -- returned 404 to the customer even though the app was
serving 200 on :3000 the whole time.
Replaced with the Node-exec family using the absolute interpreter path.
Live-verified on the demo box.
Campaign 7 catalog sweep.

Backend: wget missing from image, use python urllib instead.
Frontend: localhost resolves to IPv6, use 127.0.0.1.
Backend: add SECRET_KEY env var (v0.11.0 reads it directly).

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.
