03_wait_converge built the DB service name from the engine type:
"${DB_DEP}_${DB_DEP}" -> mariadb_mariadb. That name is only correct when
the database is central. force_shared_db deliberately leaves a
manager-pinned role carrying a literal `shared: false` alone, so
web-app-magento keeps its embedded engine, and sys-svc-rdbms deploys it as
magento_database inside magento's own stack.
The name came from the engine, which is global, and was looked up with
`docker service ls` across the whole swarm instead of the role's stack, so
the `shared` flag never entered the check at any step. Both polarities were
wrong:
variant #1 - no consumer pulls the central provider in, so
mariadb_mariadb does not exist. Run 32630684501 job 97175522113 polled it
ninety times and failed the drill, while the rescue artifact shows
magento_database at 1/1 Running and the play at failed=0.
variant #0 - matomo and mailu declare a Jinja `shared`, get force-shared
and drag svc-db-mariadb in. Job 95662862942 then reported
`db(mariadb): 1/1 Running 2 hours ago` beside `magento: Running 21
minutes ago` - green on a database magento never touches.
resolve_db_service asks the deployed swarm which service carries this
role's database: <entity>_database first, else <dep>_<dep>. The two cannot
collide, because sys-svc-rdbms renders the _database sidecar only under
`lookup('database', application_id, 'local')`. Exact-line matching, not
docker's substring name filter, per 246558a13.
Only web-app-magento changes behaviour: it is the one role that is both
pinned by force_shared_db and seen by the DB_DEP grep. matrix and
bigbluebutton never reach the DB half - their entity key carries no image,
so skip_if_no_swarm_service exits first - and discourse resolves
postgres_postgres exactly as before, in every variant.
A role that declares a DB dep no service serves now says so and gates the
app half alone, instead of polling a name nobody deployed.
diagnostics.sh carried the same guess in its container filter.

Run 32118850138 lost the :53 listener, so the sampler counts listeners.
Run 32538854067 lost DNS with the listener still bound: sockets-udp.txt
showed dnsmasq holding 0.0.0.0:53 while every forwarded query timed out,
and the sampler reported that hour as healthy.
Each tick now also records what a glibc caller gets back — for the zone
this resolver owns, derived from its own address= line, and for one name
it must forward — with the latency that caller paid. The rescue collector
probes the in-zone name too: probing external names alone cannot separate
"forwarding is gone" from "dnsmasq is gone".
The sampler now also runs on the swarm lab DNS nodes; it only ever ran in
the compose path, which is why the Magento artifact carried no sampler log
at all. Its location comes from group_vars FILE_DNS53_SAMPLER_LOG and is
required at every call site, so a run cannot quietly collect nothing.

Every script a role ships now lives under `files/<language>/`, and the unit
suite is split the same way: `tests/unit/python/` beside new sibling trees for
the other languages. `tests/lint/filesystem/test_role_files_layout.py` keeps it
that way; directories whose shape is dictated from outside carry a `.nocheck`
naming the constraint (Docker build contexts, WordPress mu-plugins, the Joomla
extension, Odoo addons, Playwright suites, the `files/test/test.sh` harness
that `test-e2e-cli` resolves generically).
This cannot be applied in halves. Moving a file and repointing what names it
are the same change: 14 references resolve only at deploy time, so the tree is
green either before or after, never between.
Those 14 were found by static resolution over every reference class, not by the
test suite -- a full `make quality-high` was green while all of them were
broken:
* 7 `src:` values built from a role variable holding a bare filename
(svc-bkp-remote-2-local, decidim, espocrm, friendica, joomla, pixelfed x2).
The variable doubles as the destination name inside the container, so the
language segment belongs at the call site, not in the variable.
* `sys-service/tasks/04_base.yml` resolved every consumer's systemd script
through `first_found(..., errors='strict')` over `files/script.{sh,py}`.
18 roles ship exactly that and have no template fallback: the play would
have died on each.
* `sys-front-inj-javascript` fell back to `<role>/files/javascript.js`; the
interface now reads `files/javascript/javascript.js`.
* `sys-front-inj-logout/templates/head_sub.j2` built the cache-busting mtime
path through `path_absolute(... 'files', ...)`.
* 4 `ansible.builtin.script:` invocations naming a bare command
(pull.py, prune.sh, set_postgres_superuser_password.sh, ganesha-serve.sh).
* `dev-python/files/shell/install.sh` pointed at a sibling role's script.
Depth-dependent paths inside the moved trees were bumped accordingly: 59
`parents[N]` computations, 12 relative climbs, and the per-role recover CLI,
whose path `cli/administration/recover/recoverers.py` still assembled from the
pre-move location.
