First real end-to-end auto-update on a live install failed like this:
Automatically updating trivy (a recovery snapshot is taken first)
Snapshotting trivy before update…
Pulling new image(s) for …
Update of failed — rolling back…
Could not roll back automatically
The app name went empty after the snapshot. Cause: bash is dynamically
scoped, so a callee assigning an undeclared variable writes the CALLER's
local of that name — and a `while read app` loop leaves it EMPTY at EOF.
webuiBackupAppStatus's dashboard generator runs at the end of every backup
and did exactly that to updaterApplyApp's `app`.
Nothing was damaged: the pull ran against an empty name, failed before
touching the image, and the rollback was a no-op on a nonexistent app.
Fixed both ends. The generator (and three gluetun loops with the same
latent leak) now declare `local app`. updaterApplyApp/updaterRollbackApp
hold the name in `_upd_app` so they no longer depend on every callee's
hygiene, and updaterApplyAll stops leaking its own loop var.
This is exactly the untested path the roadmap flagged: "apply/revert not
yet exercised end-to-end on a live install with a pending update."

If it's gluetun code, it lives with gluetun. Both functions in
scripts/config/tags/processors/tags_processor_network_mode.sh manipulate gluetun
markers / gluetun's compose, so move them into containers/gluetun/scripts/
gluetun_network.sh and rename to the per-app-hook convention:
tagsProcessorNetworkMode -> appNetworkApplyMode_gluetun
tagsProcessorGluetunForwardedPorts -> appNetworkRegisterPorts_gluetun
Central call sites are now provider-agnostic — no "gluetun" literal anywhere:
- docker_config_setup_data.sh: an app routing via CFG_<APP>_NETWORK=<provider>
triggers `appNetworkApplyMode_<provider>` + `appNetworkRegisterPorts_<provider>`
via declare -F, so any future gateway provider plugs in with no engine edits.
- uninstall_app.sh: loops every `appNetworkRegisterPorts_*` hook (each self-skips
when its provider isn't installed), so removing a routed app refreshes the
right provider with no provider name in central code.
Delete tags_processor_network_mode.sh; regenerate arrays. Verified with stubs:
default mode no-ops, gluetun-routed app fires both hooks, gluetun itself is
skipped, unknown provider is silently no-op, uninstall loop calls registerPorts.
Drive-by cleanup: 9 stale "${X_scripts[@]}" array references in app_files.sh /
cli_files.sh (gluetun + headscale from this session's moves, plus 7 pre-existing:
command/ssl/swapfile/ufw/ufwd/user — all from older refactors that left them
behind). Each expanded to nothing at runtime (harmless), but they're dead
misleading refs. Cleaned both files; every remaining array ref now points to a
real files_*.sh.
