3a1ef70cb removed the rerun workflow's rows from the actions configuration
page and left two blank lines at the end of the file, which MD012 rejects.
That is what failed the Lint job on 777f7f0fa.
The two Python files carry the reflow ruff 0.16.2 produces; 6320da703
brought that version in with the main merge. Committing it keeps the tree
matching the formatter, since scripts/lint/python.sh runs ruff format in
write mode and would otherwise rewrite them on every run.

force_shared_db flipped every DB service to shared with no exemption, so
web-app-magento's deliberate embedded MariaDB 11.4 - declared shared:
false with a comment warning that no bot may move the major underneath
it - became dead config and setup:install hit the central engine's 12.3.2,
outside Magento's supported range. The run log names the override:
'swarm force-shared: web-app-magento.services.mariadb -> shared=true'.
Exempts a DB service whose role meta declares a literal shared: false AND
whose role is manager-pinned. The second condition is not decoration:
utils/storage/nfs.py keeps a manager-pinned role's volumes node-local, and
InnoDB over NFS is why the harness force-shares in the first place. Of the
two roles with a literal local DB, magento qualifies and bigbluebutton
(unpinned) does not, so its behaviour is unchanged.
derive_includes._force_shared_db_view documents itself as mirroring
force_shared_db, so it takes the same exemption - without it the dep walk
would compute magento's include closure against the central engine while
the deploy runs a local sidecar.
The sidecar carried no deploy block at all, so an exempted service would
have been free-floating with one task per node over a single-writer
datadir. The block now comes from a container_deploy lookup shared with
sys-svc-container/templates/deploy.yml.j2, which replaces the replicas
ternary and the duplicated placement constraint there. Its unit test
caught a real defect while being written: with compose_mode_force=swarm
over DEPLOYMENT_MODE=compose the delegated compose_replicas returned
empty, emitting a deploy: key with no child.
