Add tests/lint/ansible/roles/test_compose_no_raw_image.py (strict mode):
every `image:` line in roles/<role>/templates/compose.yml.j2 must
resolve through a Jinja substitution so the underlying registry /
repository / tag is declared in the role's meta/services.yml instead of
being pinned in the compose template.
Fix the 8 pre-existing violations the lint surfaces:
- web-svc-coturn: gateway nginx → services.gateway.{image,version}
- web-svc-simpleicons: local build tag → services.application.{image,version}
- web-app-mailu: clamav antivirus → services.antivirus.{image,version}
- web-app-taiga (5×): events, async-rabbitmq, events-rabbitmq, protected,
gateway → top-level services.<name>.{image,version}

* scripts/lint/autoformat.sh:
- rename run_sort_claude_settings worker to run_claude (matches the
renamed scripts/lint/claude.sh).
- drop the EXIT trap that wiped status_dir; cleanup happens explicitly
after `wait` returns, so a parallel worker that interrupts the
parent never races a vanished status dir.
- each worker now captures its tool's exit code and writes one of
OK / SKIP / FAIL. Tolerated `expected violations remain`-style exits
(markdownlint-cli2 rc≤1, ansible-lint rc≤2) still count as OK; only
real failures count as FAIL.
- all workers run to completion regardless of individual tool failures
(so the user always sees the full picture); after the summary, the
script exits 1 if any worker reported FAIL.
* scripts/lint/sort_claude_settings.sh -> scripts/lint/claude.sh
(history preserved via git mv); update test_claude_settings_sorted.py
fix-hint accordingly.
Plus working-tree drift across roles/, group_vars/, inventories/,
requirements/, and .pre-commit-config.yaml accumulated from the
make-test setup phase regenerating generated artefacts during recent
test runs.

* scripts/lint/autoformat.sh: rename AUTOFORMAT_PARALLEL to PARALLEL,
declare it at file start with default `true`; still env-overridable.
Reword the worker comment so the literal `# shellcheck` token no
longer appears at start-of-line and trips SC1072/SC1073.
* scripts/lint/galaxy.sh: drop the GALAXY_FATAL / GALAXY_NAMESPACE /
GALAXY_PARALLEL env vars (over-engineered for a single repo). Failure
is always fatal. NAMESPACE is an internal constant. Add the same
PARALLEL env var (default `true`, env-overridable); falsy demotes the
xargs fan-out to one worker.
* docs/contributing/environment/variables.md: collapse the four
AUTOFORMAT_*/GALAXY_* rows into one `PARALLEL` row covering both
consumers.
* docs/contributing/tools/make.md: refer to `PARALLEL=0` everywhere;
add the lint-galaxy parallelism note.
Plus working-tree drift across roles/, group_vars/, inventories/, and
tasks/ that accumulated from the make-test setup phase regenerating
generated artefacts during recent test runs.

Tooling integration
* add .markdownlint-cli2.jsonc, .ansible-lint, .ansible-lint-ignore
configs (permissive day-1: cosmetic rules disabled, semantic ones on)
* extend scripts/install/lint.sh with generic install_pip_pkg helper +
ensure_ansible_lint / ensure_galaxy_importer / ensure_markdownlint_cli2
ensure_* functions (pip / npm with sudo / --user / --break-system-packages
fallbacks). install_ansible_tools now also pulls ansible-lint and
galaxy-importer; new `markdown` install group.
* extend scripts/lint/ansible.sh to run ansible-lint after the existing
syntax-check.
* add scripts/lint/markdown.sh and scripts/lint/galaxy.sh runners. The
galaxy runner parallelizes via xargs (-P=$(nproc)), prints OK/FAIL per
role, and treats `bare-name dependency` errors as success since our
roles/ tree is not a Galaxy collection layout. All other Galaxy schema
errors still fail.
* Makefile: new lint-markdown and lint-galaxy targets, both wired into
`make lint`.
* CI: new workflows lint-markdown.yml and lint-galaxy.yml; lint-ansible.yml
now installs ansible-core + ansible-lint; ci-orchestrator wires both
new lint workflows into lint-gate.
Galaxy schema fixes
* shorten the canonical `galaxy_info.company` block from three lines to
two ("Kevin Veen-Birkenbach\nhttps://www.veen.world", 45 chars) so it
stays under Galaxy's hard 50-char limit. Updated everywhere: 229 role
meta/main.yml plus _CANONICAL_COMPANY in
tests/lint/repository/test_role_meta_main_galaxy_schema.py.
* shorten 19 over-long role descriptions to <=255 chars.
* add stub READMEs for sys-svc-compose-ca and sys-utils-service-loader.
Markdown baseline fixes
* markdownlint-cli2 --fix run repo-wide (formatting normalization
across CHANGELOG, role READMEs, docs).
* manual MD041 fixes: prepend H1 in 15 files (CHANGELOG, LICENSE,
TODO.md helpers, role README templates, etc.).
* MD025 / MD003 / MD001 / MD032 manual fixes for heading-style and
list-spacing edge cases.
* role README content polish: "## Single Point of Truth (SPOT)" headings
renamed to "## User data resolution" (D3 self-label rule).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* meta/main.yml: replace every prior platforms variant (Linux,
GenericLinux, Any, Archlinux+rolling/all, distro-specific pins) with
the canonical 5-distro list (ArchLinux, Debian, EL, Fedora, Ubuntu;
versions: [all] each).
* lint: merge tests/lint/ansible/roles/test_meta_company_canonical.py
into tests/lint/repository/test_role_meta_main_galaxy_schema.py and
add a parallel canonical-platforms exact-value check; one file walk
enforces both schema conformance and the two project canonical
exact-values (company block-scalar + platforms 5-distro list).
* roles/<role>/README.md: strip emojis from H1/H2 headings (per
readme_md.md role rule), normalize the Credits block to the canonical
wording (Author/Authors/Author Information aliased; canonical block
appended where absent).
* repo-wide: revert text-drift `GenericLinux` -> `Linux` in role
description fields, README body prose, vars, j2 templates, and the
Makefile (87 occurrences). The lint docstring keeps a single
historical mention.

Collapse the prior ~10 variants of galaxy_info.company (single-line,
multi-line single-quoted, multi-line double-quoted, escaped \n,
Unicode non-breaking hyphen, Birchenbach typo, block-scalar) into one
canonical block-scalar form across every roles/*/meta/main.yml that
declares the field:
company: |
Kevin Veen-Birkenbach
Consulting & Coaching Solutions
https://www.veen.world
Add tests/lint/ansible/roles/test_meta_company_canonical.py so future
drift fails CI immediately.

Adds the missing `min_ansible_version: '2.9'` and a `platforms:`
block (single Linux entry, all versions) to 63 role meta/main.yml
files so the Galaxy-publishing recommended-field check in
tests/lint/repository/test_role_meta_main_galaxy_schema.py stops
warning. Four roles only needed `platforms`; the rest needed both.
Both fields are appended at the end of the existing `galaxy_info:`
mapping; the lint only checks presence and shape, not order.
Existing scalar values (multi-line `company:`, single-line
`description:` paragraphs, etc.) stay byte-for-byte identical:
ruamel.yaml round-trip mode with `width=10000` and the project's
`indent(mapping=2, sequence=4, offset=2)` preserves the original
formatting on every untouched key.

Two new integration lints under tests/integration/roles/meta/:
* test_variants_coverage.py — every services.yml flag declared via
the dynamic ``"{{ '<role>' in group_names }}"`` form MUST be
exercised by meta/variants.yml: at least one variant entry pins
it to literal ``true`` AND at least one pins it to ``false``.
Pairs may share variant entries — the test only checks the union
of all variants covers both polarities for every dynamic flag.
* test_services_no_self_reference.py — a role's own primary entity
(matching ``get_entity_name(role)``) MUST NOT use the dynamic form
for ``enabled`` / ``shared``. Both MUST be literal ``true``: the
role's own services.yml is loaded only when the role itself is in
group_names, so a ``'<self>' in group_names`` Jinja is tautological.
The dynamic-flag test now skips the role's own entity to avoid a
contradiction with this new guard.
Self-reference fixes (Jinja → literal ``true: true``) on 19 roles:
svc-ai-ollama, svc-db-{mariadb, openldap, postgres}, web-app-{
dashboard, discourse, keycloak, mailu, matomo, prometheus},
web-svc-{asset, cdn, collabora, coturn, file, libretranslate, logout,
onlyoffice, simpleicons}.
Variants coverage rollout (62 new + 17 merged meta/variants.yml):
* Roles without a pre-existing variants.yml get a new file with two
entries — one pinning every dynamic flag true, one pinning every
dynamic flag false. No ``- {}`` baseline (matrix runs only the
two coverage variants).
* Roles with a pre-existing variants.yml (akaunting/baserow/bluesky/
bookwyrm/flowise/fusiondirectory/jenkins/jira/joomla/keycloak/lam/
minio/phpmyadmin/postmarks/wordpress/web-svc-xmpp) keep their
matrix variants (OIDC vs LDAP, Single-Site vs Multisite, dev creds
+ TOTP-disabled realm, autologin, etc.); the all-true coverage is
deep-merged into variant 0 and the all-false coverage into
variant 1, so each role still ships exactly two matrix rounds.
* svc-ai-ollama keeps its single CI image-shrink variant; after the
self-reference fix it has no remaining dynamic flags so no extra
coverage entry is required.
* svc-db-{mariadb, openldap, postgres} drop variants.yml entirely
for the same reason.

Replace literal `enabled: true / shared: true` flags across every
roles/*/meta/services.yml with a Jinja `"{{ '<role>' in group_names }}"`
form so the per-role services map becomes the single source of truth
for shared-service co-deployment, on a per-host basis. Inventory build
already runs through the templar before reaching the static `is True`
check, so runtime behaviour is unchanged; the new form only opens up
static-analysis and CLI tooling to the group-aware semantics.
Mechanism + lint:
- New integration test tests/integration/roles/meta/test_services_
dynamic_flags.py enforces the dynamic shape per top-level service
entry. Registered service keys must reference the registry-resolved
provider role; covered keys (e.g. oauth2 -> web-app-keycloak via
the new `covers:` block) reference the covering role.
- Two suppression placements documented in docs/contributing/actions/
testing/suppression.md: per-flag inline `# nocheck: dynamic-flag`
for databases (`enabled: true` stays literal, `shared` resolves
dynamically) and block-level above the key for entries whose both
flags legitimately stay literal (`css`, `javascript`, role-local
`redis`, `recaptcha`, `hcaptcha`, role-local containers with
`shared: false`).
Registry + helpers:
- utils/service_registry.py: new `is_explicit_truth(value)` helper
accepts `True` literal OR a Jinja string carrying `in group_names`.
Adopted by `resolve_service_dependency_roles_from_config`,
`ServicesResolver._is_enabled_shared`, `test_web_app_email_
integration`, `test_prometheus`, `test_universal_logout`, and the
run_after-explicit guard so static analysis keeps resolving deps.
- New `covers:` field on a primary service entity declares
transitive equivalents (web-app-keycloak.covers: [oauth2]).
Exposed via `build_role_to_covered_keys` and
`build_covered_key_to_role`, replacing the previously hard-coded
`_TRANSITIVE_SERVICE_EQUIVALENTS` / `_SPECIAL_REFERENCE_ROLE` maps
in the run_after and dynamic-flag tests.
Bulk migration:
- All 80 roles/*/meta/services.yml files migrated to the dynamic
form. DB consumer keys (mariadb, postgres, ldap) keep
`enabled: true # nocheck: dynamic-flag` literal with a dynamic
`shared`. Block-nocheck applied to css/javascript/recaptcha/
hcaptcha and role-local containers (e.g. mailu's admin/imap/smtp/
antispam/antivirus/oletools/webdav/fetchmail/webmail/resolver/
front, nextcloud's talk).
- web-app-prometheus's primary entity now declares
`provides: prometheus` + dynamic flags so the registry recognises
it as a service provider. Consequence: tasks/01_core.yml split out
with `- include_tasks: utils/once/flag.yml` as the first task and
tasks/main.yml reduced to the standard run_once-guarded loader.
- Seven minimal no-login apps (web-app-hugo, -bridgy-fed, -chess,
-littlejs, -navigator, -mini-qr, -mig) gained an explicit
`logout: { enabled: false, shared: false }` opt-out (with
`# nocheck: dynamic-flag` block-marker) to satisfy the universal-
logout schema check.

req-011 — descriptive role-level metadata
* Move logo / homepage / video / display out of
meta/main.yml.galaxy_info into a new project-owned
roles/<role>/meta/info.yml (file-root convention, no `info:` wrapper).
* 78 role meta/main.yml files migrated via ruamel round-trip
(key-order / quoting / inline-comments preserved). Roles with none
of the four fields are left untouched (no empty info.yml created).
* web-app-dashboard/lookup_plugins/docker_cards.py reads logo +
display from meta/info.yml; description / galaxy_tags continue to
come from galaxy_info (Galaxy-spec fields).
* docker_cards.py now routes ALL its file reads through the
process-wide caches: load_yaml_any for vars/main.yml,
meta/main.yml, meta/info.yml; read_text from utils.cache.files for
README.md. The orphan `import yaml` is gone.
New utils/cache/files (renamed from tests/utils/fs)
* The process-wide filesystem cache (read_text, iter_project_files,
iter_project_files_with_content, _all_project_files) is not
test-specific; it now lives under utils/cache/files.py next to the
other process-wide caches. 34 consumer imports rewritten across
tests/ and docs/. The empty tests/utils/ package is removed.
* New unit suite tests/unit/utils/cache/test_files.py — 12 cases
covering read_text, iter_project_files (skip-dirs, extensions,
exclude_tests, exclude_dirs, walk-cache invariants), the combined
iterator, non-UTF-8 silent skip, and _reset.
utils/cache redundancy cleanup
* applications.py + users.py + cli/create/inventory/services_disabler.py
drop their direct yaml.safe_load calls and their private
_load_yaml_mapping/_load_yaml_variant_list copies; everything routes
through utils.cache.yaml.load_yaml / load_yaml_any. The dead
utils.cache.base._load_yaml_mapping is removed.
* users.py:_load_store_users (tokens.yml read) likewise migrated.
* _load_yaml_variant_list moves out of base.py to applications.py
(its only consumer) and is renamed _load_variants_overrides — also
routes through the cached loader now.
* utils.cache.yaml._reset_cache_for_tests is renamed _reset (kept as
alias) for parity with the per-domain reset helpers.
* utils.cache.files grows a _reset() that clears its two LRU caches.
* utils.cache.__init__._reset_cache_for_tests now orchestrates ALL
six caches (applications, users, domains, base, yaml, files) so
tests get clean state across cache layers — needed because
applications/users now share the yaml cache and would otherwise
serve stale parses across reset boundaries.
* utils.cache.files imports PROJECT_ROOT from base instead of
redefining it.
* tests/unit/utils/cache/test_data.py + test_base.py: obsolete
TestLoadYamlMapping / TestLoadYamlVariantList classes deleted
(covered by test_yaml.py + test_variants.py).
* README.md updated for the new module list (files, yaml) and the
six-module orchestrator.
Galaxy schema lint
* tests/lint/repository/test_role_meta_main_galaxy_schema.py: split
galaxy_info field requirements into hard-required {author,
description, license} and soft-recommended {min_ansible_version,
platforms}. Soft-recommended -> emit a GitHub Actions ::warning::
annotation via utils.annotations.message.warning (titled
"meta/main.yml galaxy_info" with file= pointing at the offender),
no test failure. Rationale: min_ansible_version + platforms are
only enforced by Galaxy when *publishing*, which Infinito.Nexus
does not do.
* Galaxy lint goes green (was 226 offenders before req-011 +
license_url/repository/documentation strip; was 62 before this
relaxation; now 0 hard offenders, 62 soft warnings).
* roles/svc-opt-keyboard-color/meta/main.yml: backfill `license`
(only role missing the hard-required field).
New lint
* tests/lint/repository/test_role_meta_info.py — enforces meta/info.yml
file-root convention, the four-field allowlist (logo, homepage,
video, display), and shape (logo.class string, homepage/video
non-empty strings, display bool). Also fails if any
meta/main.yml.galaxy_info still carries one of the four migrated
fields.
Docs
* docs/contributing/design/services/layout.md: new section
"Descriptive Role-Level Metadata — meta/info.yml" with allowed-
fields table, optionality rule, materialised path, and consumer
note. File-Layout table grows the meta/info.yml row;
meta/main.yml row gets the explicit "no logo/homepage/video/display"
note. req-011 added to header and Related Pages.
* utils/cache/README.md: files.py + yaml.py rows added; six-module
reset orchestrator documented.
Validation
* Unit: 1573 passed.
* Lint: 55 passed.
* Integration: 161 passed (1 skipped) via pre-commit hook.

These three sub-keys lived under `galaxy_info:` purely as a workaround
because Galaxy silently ignores unknown keys (same pattern as the
`run_after` / `lifecycle` migration in req-010). The new lint
`tests/lint/repository/test_role_meta_main_galaxy_schema.py` rejects
them, and no consumer in `plugins/`, `utils/`, `cli/`, `filter_plugins/`
or `roles/` reads any of them, so the strip is safe.
Round-trip via ruamel.yaml so the remaining `galaxy_info:` block keeps
its key order, quoting style and inline comments.
224 files touched. Remaining lint offenders after this commit are still
present (`logo`, `homepage`, `video`, plus a handful of roles missing
required Galaxy fields like `min_ansible_version` / `platforms` /
`license`); those are a separate decision and not folded into this
change.

Single atomic landing for three back-to-back role-meta refactor requirements
(see docs/requirements/008-role-meta-layout.md, 009-per-role-networks-and-ports.md,
010-role-meta-runafter-lifecycle-migration.md).
req-008 — role meta layout
* Move every role's metadata under meta/<topic>.yml with file-root
convention (no wrapping key matching the basename):
- schema/main.yml + config/main.yml.credentials → meta/schema.yml
- users/main.yml → meta/users.yml
- config/main.yml.server → meta/server.yml
- config/main.yml.rbac → meta/rbac.yml
- config/main.yml.compose.services + every other top-level key
of config/main.yml inlined under <entity>.<key>
→ meta/services.yml
- config/main.yml.compose.volumes → meta/volumes.yml
* Drop the legacy schema/, users/, config/ directories from every role.
* meta/schema.yml: support nested credential keys, optional `default:`
field (Jinja literal, not rendered/validated/regenerated), implicit
`algorithm: plain`.
* Materialised paths drop the `compose.` prefix:
compose.services.<e>.<…> → services.<e>.<…>
compose.volumes.<k> → volumes.<k>
<former-top-level>.<…> → services.<entity_name>.<former-top-level>.<…>
* Update every Python consumer (utils/cache, utils/manager, utils/applications,
plugins/lookup, plugins/filter, cli/*) plus every Jinja template, vars/*.yml
and task file to the new paths.
* No legacy fallback. Repository-wide grep for `compose.services.` /
`compose.volumes.` / `schema/main.yml` / `users/main.yml` / `config/main.yml`
is empty outside docs/requirements/ and tasks/utils/migrate_meta_layout.py.
* Add tests/lint/repository/test_role_meta_layout.py guarding against the
old paths returning, and an explicit lint guard that meta/variants.yml
files do not carry a `compose:` wrapper.
req-009 — per-role networks/ports
* Move group_vars/all/08_networks.yml.defaults_networks.local.<role>.{subnet,
dns_resolver} into roles/<role>/meta/server.yml.networks.local.{subnet,
dns_resolver}.
* Delete group_vars/all/09_ports.yml entirely; ports now live on the
service entity that exposes them at
roles/<role>/meta/services.yml.<entity>.ports.{inter,local,public}.
* Rename + int-cast every former top-level `services.<entity>.port`
field to `services.<entity>.ports.inter` (single int).
* Always-category-keyed maps for ports.local / ports.public; relay
spans use {start, end} integers.
* Add PORT_BANDS map to group_vars/all/08_networks.yml — single source
of truth for the per-<scope>.<category> band ranges, consumed by both
the new CLI helpers and the lint test.
* New CLI helpers (cli meta ports suggest, cli meta networks suggest)
walk the live role tree gap-first then increment-fallback, with
deterministic output and non-zero exit on capacity overflow.
* cli create role consumes both helpers when scaffolding a new role.
* Lint extensions: bare-int port shape rejection, host-bound port
collision check (single ints + relay span integers, inter excluded),
band-membership check with documented allow-list for the legacy
web-app-bigbluebutton.bigbluebutton.local.http: 48087 entry.
req-010 — run_after / lifecycle migration
* Move galaxy_info.run_after and galaxy_info.lifecycle out of
meta/main.yml into meta/services.yml.<primary_entity>.{run_after,
lifecycle}; <primary_entity> is the value returned by
get_entity_name(role_name).
* For multi-entity roles whose primary entity has no compose service
(web-app-bluesky → bluesky, web-app-matrix → matrix, desk/dev/drv/
gen roles), create a dedicated metadata-only top-level entry under
<primary_entity>.
* Introduce utils/roles/meta_lookup.py with get_role_run_after /
get_role_lifecycle that resolve <primary_entity> once and read from
meta/services.yml; degrade gracefully when meta/services.yml is
absent OR the field is absent; raise MetaServicesShapeError when the
file exists but is malformed.
* Update every consumer (utils/service_registry, utils/invokable,
cli/meta/applications/resolution/run_after/__main__, cli/meta/roles/
lifecycle_filter/__main__, cli/meta/applications/resolution/combined,
cli/build/{tree,graph,role_include}, cli/deploy/development/{common,
init,deps,deploy}, plugins/filter/canonical_domains_map, etc.) to
use the helper.
* Lint guards: no run_after/lifecycle in meta/main.yml; lifecycle
values restricted to {planned,pre-alpha,alpha,beta,stable,deprecated};
run_after/lifecycle never on a non-primary entity; empty run_after
lists rejected.
Also folded into this change set
* services_disabler now writes `services.<svc>.{enabled,shared}` into
host_vars instead of the old `compose.services.<svc>.{...}` path; the
discover/find pair walks meta/services.yml and only treats entries
carrying enabled/shared/provides as provider declarations (so
metadata-only entries from req-010 do not create spurious provider
rows).
* service_registry skips `run_after` deps whose target was filtered
out via SERVICES_DISABLED instead of failing the whole load.
* cli/mirror/resolver and cli/create/inventory/mirror_overrides emit/
consume the new applications.<role>.services.<svc>.image shape
(mirror.md updated to match).
* utils/domains/list.build_applications_from_roles now reads
meta/server.yml directly (it had been silently returning {} since
config/main.yml stopped existing).
* utils/roles/resource_validation.filter_roles_by_min_storage reads
meta/services.yml.<entity>.min_storage instead of the legacy
compose.services path.
* web-app-bluesky pre-clones the social-app build context BEFORE
sys-svc-compose so the build context is on disk by the time
sys-stk-front-proxy/tasks/main.yml flushes the docker build handler.
* 4 meta/variants.yml files (svc-ai-ollama, web-app-phpmyadmin,
web-app-wordpress, web-app-keycloak) lose their `compose: services:`
wrapper so deep-merge over meta/services.yml lands on the new
file-root shape.
Validation
* Unit tests: 1571 passed.
* Lint tests: 50 passed.
* Integration tests: 161 passed (1 skipped).
* Full-cycle fresh-purged-apps deploy succeeded for the 8-app validation
set: web-app-{nextcloud,wordpress,yourls,bigbluebutton,bluesky,gitea,
discourse,mattermost}.
