The greedy set-cover retires a role's variant-0 row when an earlier row of another role embeds it, on the premise that embedding pulls the provider at variant 0. The premise is a property of the pair, not of the coverer: a job's round index is the primary role's own variant index, and plan_dev_inventory_matrix hands each pulled-in dependency 'round_index if round_index < its variant count else 0'. A variant 3 coverer therefore pulls a 3-variant provider at 0 and a 14-variant provider at 3.
Coverage now asks that question per pair instead of assuming the answer. Nothing changes on the current tree, where 53 rows are covered before and after: the discovery sort ends on 'asc variant', so a role's variant-0 row is always green before its higher ones and gets to cover first. That is a property of a sort key in default.env, not of this code, and 2633 embed pairs would fall the wrong way without it.

A round deploys a provider once, so the role that pulls it in is the only place that can say how lean it has to be. A variant entry may now carry any application config topic under a service it depends on: a mapping deep-merges, so naming one key changes that key alone, and null empties the topic. Empty was the case that needed a marker of its own, because merging an empty mapping is a no-op and would leave exactly the services the round was trying to shed.
The topic vocabulary and the merge semantics live in utils.roles.applications.topics, which is also where resources.py now gets them rather than spelling the same null-or-merge out a second time. Collecting who demands what stays in the inventory tree, refuses two roles demanding different values for one provider in the same round, and skips a role's own entity entry so the existing services.<own>.users declarations are not read as overrides.
The CI set-cover learns the same fact. Its greedy cover retires a role's variant-0 row when an earlier row of another role embeds it, on the stated premise that embedding pulls the provider's variant 0. A variant that dictates that provider's config breaks the premise from the other side: whatever ran, it was not the provider as the provider declares it. Such a pair now covers nothing, so the retired row keeps its job, its artefact and its verdict.
Measured on the current tree: 20 override pairs, 41 covered rows before and after, so nothing is revoked today. The rule bites the moment an override lands in a row that covers.

The instructions test held a job of its own that picked one random role per
run, so a README's Production block was proven roughly once per 265 roles.
The replay now rides on a deploy row instead: no extra runner, and every role
the sweep touches gets its documented one-command deploy exercised.
The row is the role's smallest variant -- fewest services enabled -- because
that is the shape the README describes, and it is chosen among the variants
the sweep actually deploys, so a row cut as redundant coverage cannot silently
drop the role from the test. A role qualifies only when its README carries a
Production block and the guide's own mode is one the role runs and tests.
The marked entry carries the guide mode in `instructions` and a 📖 in its job
title, between the variant number and a priority ⭐. The guide mode is
independent of the mode the rotation gave the row: a swarm row still replays
in compose. The step runs last in the deploy job, after the swarm teardown,
because the replay deploys the role a second time and needs the runner's
ports.
call-test-instructions.yml, cli.meta.ci.guide_select and the `instructions`
dispatch input go with it. `redundant()` moves next to the marker so the
chunker, the plan table and the marker share one definition.
The plan table trades its 📊 Weight column for 📖 Instructions; nothing read
the weight any more, so it leaves the matrix entries too.

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.
