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.
