bookstack-db, kimai-db, nextcloud-db, romm-db each gain `MARIADB_AUTO_UPGRADE=1` in the db
service's environment list. Operator ruling 2026-09-13 on the measurement in
felhom.eu/documentation/audits/SPIKE-r459-mariadb-upgrade-2026-09-06.md: an unconverted datadir
is stable but never heals; the conversion costs ~7 s and the engine backs its system tables up
first. MARIADB_DISABLE_UPGRADE_BACKUP is deliberately left UNSET — that backup is the precaution.
NO `image:` line changed, so `catalog_since` does NOT move — the CLAUDE.md rule ties it to an
image change and this is not one. Do not "fix" that.
The setting is inert until an engine major actually moves, and none may until Slice 4 (R-448)
ships — see the engine-major rule in CLAUDE.md and scripts/check-engine-major.py (next commit).
The eleven PostgreSQL templates are untouched: R-463 is a different engine and a different
measurement.
REUSE.md: one convention row for the MariaDB sidecar env, same commit.

MAJOR (bookstack): v26.05 needs storage/fonts writable for PDF export; revision
viewing is now a separate permission. Fresh deploys unaffected; flagged for the
future in-place update path.
MAJOR (mariadb): 11.6 -> 12.3.
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.
