Audit of per-app hooks/tools found 19 of 33 apps whose helpers would have
operated on the BASE app after cloning. Two general causes, both fixed by
rewriting classes rather than patching apps:
- Container references escaped the rewrite whenever a flag sat between the
docker verb and the target (`docker exec -u git gitea-service …`), since the
old rule only matched a name immediately after the verb — and the hyphenated
form missed the `<type>_` rule too. Hook trees now get the same discovered
identity rename the compose does, reading names from the TYPE's compose since
the clone has already been rewritten by then. Safe to apply broadly: the
compose pass runs first and aborts for any app whose identities aren't
<type>-prefixed, so a bare word like stoat's `api` never reaches it.
- Hooks that build the deployed path as "${containers_dir}<type>/..." instead
of "$containers_dir$app_name/..." read and WROTE the base app's files —
adguard's auth adapter edits AdGuardHome.yaml, so an instance would have
rewritten the original's config. The trailing slash is optional in the match:
dashy tests [[ -d "${containers_dir}dashy" ]] and gluetun cds into it, both
ending at the quote. Only the first path component is touched, so
${containers_dir}prometheus/prometheus/... keeps its inner segment.
Re-audit: all 33 apps with hook trees are clean. Stoat still leaks, but it is
refused at the compose stage and never reaches this code.
Volumes audited too, and need no changes: no app uses named volumes, so the
./relative bind mounts every app uses resolve inside each instance's own
deployed dir. The absolute sources that exist are host or in-container paths
correctly shared read-only (/etc/localtime, /sys, /etc/ssl/certs). Jitsi's
${CONFIG} is set per-app by its own hook to $containers_dir$app_name/... and so
follows the slug.
Bookstack's rewritten tool tree is byte-identical to the live instance's across
all 8 files, so the running instances are unaffected.

The registry helpers rejected any repo containing a dotted host segment,
which caught 'docker.io/authelia/authelia' — Docker Hub spelled out in
full. Those apps were silently skipped by tag enumeration and version
laddering. Strip the docker.io/ and index.docker.io/ prefixes before the
host check; genuinely third-party registries (ghcr.io, quay.io, lscr.io)
are still correctly skipped.
Found by auditing every app's anchor image.

Foundation for stepped upgrades. Answers one question only — WHICH
versions, in WHICH order — with no side effects, so it can be tested
exhaustively. Applying the rungs is a separate job.
Nextcloud refuses to skip a major ("Updates between multiple major
versions and downgrades are unsupported") and will not start; databases
behave the same way about their data directory. For those apps 31 -> 34
is three upgrades, each with a migration that must finish before the
next begins.
Built by PROBING each candidate rung, not by enumerating tags — because
enumeration is provably unsafe here. Docker Hub pages at 100 ordered by
recency, and the first real-registry run proved the danger: it produced
v4.2 -> v4.4 -> v4.5 -> v4.6 for mastodon, silently skipping v4.3, which
exists (HTTP 200) but had fallen off the newest-100 listing. Skipping a
rung is the precise failure this file exists to prevent, so the ladder is
now built by incrementing and probing: v4.2 -> v4.3 -> v4.4 -> v4.5 ->
v4.6, 4 steps.
Guarantees: same shape only (never 31-fpm-alpine onto 31-apache),
strictly ascending, never a downgrade, rolling tags refused outright, and
a version upstream never published is stepped over only because the probe
said so. If a continuous path to the target cannot be constructed it
returns 1 and prints nothing — refusing to guess, because a wrong ladder
means a skipped migration.
20 unit tests, including the exact listing-truncation case above and the
numeric ordering that would otherwise drive an app backwards (0.9 vs
0.10). Real registry: nextcloud 3 steps, mastodon 4, stalwart current.
