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.

A backup generation stores databases as sql dumps, not as a file tree
(--dump-only-sql), and the recover chain only ever restored trees:
`git grep sql HEAD -- cli/administration/recover utils/recovery` was
empty. An operator running `recover full` after a real loss got their
files back, their databases untouched, and an exit code of 0.
Adds the missing leg as a fifth recoverer, planned right after the
volume steps so the dumps land once the volumes are back. Three
properties make it a restore rather than an attempt:
- It refuses while a consumer of that database runs. `--empty`
pre-cleans the schema in one psql session and replays in the next; a
booting consumer recreates it in between and the dump's own CREATE
TABLE fails. That is what turned CI red with `relation
"ar_internal_metadata" already exists`.
- The engine is read, not guessed: the service key in the consuming
role's meta/services.yml, the same value that fed the backup seed.
The two previous call sites each sniffed it from the container image
and could disagree.
- The dump's own header states which server it came out of, and that is
compared against the running engine before the pre-clean drops
anything. Forward across a major version is the upgrade path and
stays allowed; backward is refused. The version deliberately does not
travel in databases.csv: that file is written at seed time and would
state the version deployed back then, and a generation copied to
another host carries its header along while a csv row stays behind.
Mind the header formats, they are not symmetric - postgres puts
`Dumped from database version` on line 7, while mariadb's line 2 opens
with mariadb-dump's own version and only the tab-separated `Server
version` line names the server. Both are pinned as test fixtures,
captured from postgres:17-alpine and mariadb:11 themselves.
baudolo is untouched: nothing beyond the credentials it already carries
is read from databases.csv, and no upstream format changes.

Second diagram in the backup architecture doc: when the units run
during a deploy, keyed on MODE_BACKUP and install vs update, including
the preload instant snapshots, the end-of-play remote pull and the
abort-on-failed-snapshot semantics.

Add utils/recovery/base.py DirectoryRecovery: a service-backed pre-recover
(start the role's backup unit first) + rsync -a --delete mirror. Each
svc-bkp-* role gets a files/recover.py subclass (volume resolves the docker
mountpoint, nfs mirrors the export, local-2-device opens the newest LUKS
snapshot across machine hashes) or a documented one-way opt-out
(remote-2-local recover.py.nocheck). A lint guard enforces every svc-bkp-*
role ships a recover.py and a ## Recover README section; docs/architecture/
backup.md documents the end-to-end schema. Unit tests cover the base flow,
the per-role class logic and every recover.py main() CLI wiring.
