kevinveenbirkenbachandClaude Opus 4.7 fe54854fe5 refactor(resolver): variant-aware combined resolver and per-round include
Single SPOT for matrix-deploy topology
=======================================

Before this change two paths derived the deploy plan from different
sources and could disagree:

 * Group inclusion (`--include` / `group_names`): driven by
   `cli.meta.applications.resolution.combined.CombinedResolver`,
   which read each role's `meta/services.yml` raw and ignored
   `meta/variants.yml` entirely. A variant that flipped
   `services.<X>.enabled` to a literal `true` did NOT pull `<X>`'s
   provider role into the deploy plan.

 * Inventory bake (`host_vars/applications.<app>.*`): driven by the
   variant-aware payload merge in `cli.deploy.development.inventory`,
   so the role saw the variant-merged services map at deploy time.

The split surfaced concretely for `web-app-wordpress` variant 0
(`services.discourse.enabled: true` in `meta/variants.yml`): the
inventory baked `discourse.enabled = true`, the wp-discourse plugin
task gate fired, and the install loop tried `docker exec discourse`
against a container the variant-blind resolver had never pulled.

This commit collapses both consumers onto the same per-round,
variant-merged services map. The variant-aware resolver (Phase 1+2)
is the additive plumbing, but the deploy/init wiring (Phase 3-5) is
what actually changes behaviour at runtime.

Variant-aware resolver (Phase 1+2)
----------------------------------

`role_introspection.load_shared_service_roles_for_app` accepts a
`services_override` kwarg; `CombinedResolver.__init__` accepts a
`{role_name: services_dict}` map and routes it through the loader.
A `CombinedResolver` instance is round-specific when overrides are
supplied — its per-role edge cache is variant-resolved, do NOT reuse
across rounds. The combined-resolver CLI gains
`--services-overrides <path>`.

`cli.deploy.development.deps.resolve_run_after` threads the
in-container path of the overrides JSON into the resolver
invocation.

Per-round include planner (Phase 3)
-----------------------------------

`cli.deploy.development.inventory.plan_dev_inventory_matrix` now
takes `primary_apps` (just the user-named apps) instead of a
pre-resolved `include` list and returns a 4-tuple per round
`(round_index, inv_dir, round_variants, include_R)`. Per round it:

 1. Computes `round_variants` clamped to each primary's variant
    count.
 2. Builds variant-merged services overrides for every role with a
    `meta/variants.yml`, picking that role's variant for the round
    (clamped) — so transitive deps with their own variants follow
    the round.
 3. Runs `CombinedResolver(services_overrides=...)` per primary and
    unions the result with the primary apps in user order.
 4. Extends `round_variants` with the discovered deps' clamped
    variant indices so the deploy step's per-round purge logic stays
    accurate.

`build_dev_inventory_matrix` keeps its name but signature changes:
it now takes `primary_apps` and an optional `include_filter` for
SERVICES_DISABLED-style consumer filters.

Init / deploy wiring (Phase 4-5)
--------------------------------

`init.py` and `deploy.py` consume the per-round `include_R`
directly, drop the old `resolve_deploy_ids_for_apps` pre-resolution
step, and apply the SERVICES_DISABLED provider filter on the
include set so the inventory `--include` flag and the final ansible
deploy ids stay in lockstep.

Behaviour invariance for non-variant roles
------------------------------------------

Apps with no `meta/variants.yml`, or without a `services.<X>.enabled`
override on any variant, behave identically to before:

 * The override map for those roles is empty — resolver falls
   through to the disk-only path.
 * Per-round `include_R` collapses to the same set every round.
 * Inventory bake outputs the same `applications.<app>.*` shape.

The behaviour change is scoped to roles that legitimately use
variants to flip topology. In the current repo only
`web-app-wordpress` is affected (variant 0 pulls
`web-app-discourse` in; variant 1 leaves it out, exercising the
multisite-without-discourse path).

Test surface
------------

 * `tests/unit/cli/deploy/development/test_inventory.py` updated
   for the new planner signature, mocking
   `_resolve_round_include` / `_build_services_overrides_for_round`
   so the planner's tuple shape is asserted independently of the
   live resolver.
 * `tests/unit/cli/deploy/development/test_matrix_deploy.py` adds a
   `_entry()` helper that defaults `include` to the keys of
   `round_variants`, so existing fixtures stay terse — round 0 of
   the deploy loop deploys whatever is in `include_R`, and the
   variant-aware planner naturally emits the same set.
 * `tests/unit/utils/cache/test_data.py` pins the planner contract
   (`primary_apps=`, 4-tuple plan entries with `include_R`).
 * `tests/utils/__init__.py` added so the
   `tests.lint.filesystem.test_init_files` lint test passes
   end-to-end (the directory existed in the tree without an
   __init__.py and tripped the lint).

Verification
------------

 * `make test` green (162 tests, 1 skipped) on the merged tree.
 * `make deploy-fresh-kept-apps APPS="web-app-wordpress"
   FULL_CYCLE=true SERVICES_DISABLED="matomo,email"` end-to-end:
   round 0 (variant 0, single-site + Discourse integration) and
   round 1 (variant 1, multisite) each ran PASS 1 (sync) and PASS 2
   (async), all four passes with `failed=0 rescued=0`. Round 0's
   per-round include contained `web-app-discourse`; round 1's did
   not — exactly the variant-driven topology the resolver is
   supposed to produce.

The unrelated Joomla CLI install race (CI run 25079786137 `Deploy
web-app-joomla`) is parked separately as infinito-nexus/core#209;
its candidate fix is in that issue body, not in this commit.

kevinveenbirkenbachandClaude Opus 4.7 b3de2a4d7c refactor(meta): land req-011 meta/info.yml + utils/cache cleanup
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.

kevinveenbirkenbachandClaude Opus 4.7 ed04dad5d5 refactor(meta): land req-008/009/010 role-meta layout/networks/ports/run_after migration
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}.

kevinveenbirkenbachandClaude Opus 4.7 9c35909752 refactor(utils/cache): split data.py into base/applications/users/domains
The 934-line `utils/cache/data.py` monolith mixed cross-cutting helpers
(constants, yaml-loaders, deep-merge, signatures, render machinery)
with three independent domain caches (applications, users, domains).
Per the KISS/SPOT/DRY guidelines, split it along domain boundaries so
each file has a single, well-scoped responsibility:

  utils/cache/__init__.py     — package; owns _reset_cache_for_tests()
                                orchestrator
  utils/cache/base.py         — cross-cutting helpers: constants,
                                yaml-loaders, _deep_merge, cache-key +
                                content-fingerprint signatures, the
                                cross-domain re-entry guard, and the
                                templar-render machinery (the only
                                ansible-coupled symbol, lazy-imports
                                its dependency)
  utils/cache/applications.py — variants + defaults +
                                get_merged_applications. Strictly
                                ansible-free at import time so the
                                GitHub Actions runner-host CLI path
                                (cli.deploy.development.init →
                                plan_dev_inventory_matrix →
                                get_variants) keeps working without
                                ansible installed
  utils/cache/users.py        — user defs, token store hydration,
                                alias materialization,
                                get_user_defaults, get_merged_users
  utils/cache/domains.py      — get_merged_domains, derived from the
                                merged applications view
  utils/cache/data.py         — DELETED. Façade is gone; the package
                                exports nothing the domain modules
                                don't already

Backward-compat: the facade was deleted (per operator request) and all
36+ consumers — 18 plugins, 2 CLI entry points, 9 test files, 4 doc
files, plus a role-internal lookup_plugin — were rewired to import
directly from the owning domain module. `_reset_cache_for_tests` is
now exposed at `from utils.cache import _reset_cache_for_tests`.

Tests added (per-module, focused):
  tests/unit/utils/cache/test_base.py            (31 cases)
  tests/unit/utils/cache/test_applications.py    ( 9 cases)
  tests/unit/utils/cache/test_users_module.py    (21 cases; suffix
                                                  disambiguates from
                                                  the existing
                                                  tests/unit/plugins/
                                                  lookup/test_users.py)
  tests/unit/utils/cache/test_domains.py         ( 6 cases)

The ansible-block invariants from CI runs 24934007615 and 24935979190
are now pinned via subprocess isolation: each ansible-less import test
spawns a fresh `python3 -c '…'` with a meta_path filter denying every
`ansible*` import and asserts the import + invocation succeed in that
clean process. The earlier in-process sys.modules-manipulation shims
fragmented module identity and broke under Python 3.13 inside the
infinito container; subprocess isolation has neither problem.

Doc-style audit (per docs/contributing/documentation.md):
  - Removed em-dash from utils/cache/README.md (split into two
    sentences)
  - Updated stale `utils.runtime_data` reference in
    docs/contributing/design/matrix-deploy.md
  - Removed two SPOT self-declarations
    (docs/agents/files/group_vars/applications.md and
    docs/contributing/artefact/files/plugins/lookup/users.md) per
    the documentation rule that SPOT status is conferred by
    cross-links, not by the page asserting it about itself

Empirical proof:
  - All four domain modules import without ansible (subprocess
    isolation tests)
  - get_variants(roles_dir=ROLES_DIR) returns 99 apps in the
    ansible-blocked subprocess
  - 142 cache tests + 1085 wider-suite tests pass; the only
    remaining failures (test_host_vars free-function fixture bug,
    test_runtime_performance timing flake) are pre-existing and
    unrelated to this refactor (verified via `git stash`).

kevinveenbirkenbachandClaude Opus 4.7 8e4886d705 fix(utils/cache): allow utils.cache.data import without ansible
CI run 24934007615 broke every per-app deploy job (test-deploy-server,
test-deploy-universal — ~70 jobs) with the same trace:

    cli/deploy/development/init.py:10
      → cli/deploy/development/inventory.py:26
        → utils/cache/data.py:15
          → plugins/lookup/application_gid.py:7
            → ansible.plugins.lookup
    ModuleNotFoundError: No module named 'ansible'

`scripts/tests/deploy/ci/dedicated.sh:167` runs `python3 -m
cli.deploy.development init` directly on the GitHub Actions runner host
to materialise the dev inventory. The runner Python (3.12) ships without
`ansible`, but `utils.cache.data` was eager-importing
`ApplicationGidLookup` (extends `ansible.plugins.lookup.LookupBase`) and
`_templar_render_best_effort` (uses `ansible.errors.AnsibleError`) at
module scope. The cheap `get_variants` entry point — the only thing the
init step actually needs — therefore refused to import.

Move both ansible-coupled imports into the call sites that genuinely
need them:

- `_templar_render_best_effort` is now a lazy import inside
  `_materialize_builtin_user_aliases` and `_render_with_templar` (the
  two functions whose closures use it).
- `ApplicationGidLookup` is now a lazy import inside `_build_variants`
  (the only caller that instantiates it). The forward reference in
  `_build_role_base_config(gid_lookup: ApplicationGidLookup)` keeps
  working because `from __future__ import annotations` is already in
  effect; a `TYPE_CHECKING` import keeps static type checkers happy.

`merge_with_defaults` is pure-Python and stays at module scope.

Add `TestImportableWithoutAnsible` (two tests, one for `utils.cache.
data.get_variants`, one for the full
`cli.deploy.development.inventory.plan_dev_inventory_matrix` chain) that
artificially blocks `ansible` via a `MetaPathFinder` and asserts the
imports still complete. Without this guard a future eager import of an
ansible-coupled symbol would silently break ~70 CI jobs again.

kevinveenbirkenbachandClaude Opus 4.7 0639fb2fa7 fix(deploy): unblock matrix-deploy of web-apps on dev runtime
Four independent bugs were each blocking the autonomous
fresh-purged-apps iteration of web-app-{openwebui,wordpress,nextcloud,
phpmyadmin,yourls}; bundling them so the pipeline keeps running.

- cli/core/discovery.py: stop walking argv prefixes at the first flag
  or path-shaped arg and ignore OSError so the matrix-init's
  `infinito create inventory <abs-path> --vars '<huge JSON>'` no longer
  hits ENAMETOOLONG inside `is_dir()`. New regression tests pin both.
- utils/cache/data.py: when this module moved to utils/cache/data.py,
  PROJECT_ROOT silently slid one level deep, pointing ROLES_DIR at a
  non-existent `<repo>/utils/roles`. Implicit lookups returned empty
  defaults so `lookup('users','contact')` failed at deploy time as if
  the user weren't defined. Use parents[2] and pin the invariant in a
  new regression test.
- roles/web-app-keycloak/vars/main.yml: KEYCLOAK_PER_APP_LDAP_ROLES_MAPPER
  inherited `subComponents`/`id` from the realm-import dictionary's base
  `ldap-roles` mapper. kcadm rejects those keys on `create components`
  ("Unrecognized field 'subComponents'"), with stderr swallowed by
  `2>/dev/null` in upsert_app_mapper.sh. Strip both keys exactly like
  update/05_ldap.yml already does for the shared mapper.
- scripts/tests/deploy/local/deploy/fresh-purged-app.sh: pass
  `RUNTIME=dev` through `--vars`, otherwise the host process running
  init falls back to `detect_runtime() == "host"` and the Playwright
  E2E gate (`RUNTIME in [dev, act, github]`) never fires.

kevinveenbirkenbach 12dba01156 refactor(utils): consolidate cache modules into utils/cache/ package
Both in-process cache layers — the cached YAML loader and the cached
runtime-data getters — now live next to each other under
`utils/cache/`. The package gains a README that documents the
"orthogonal layers, no third cache" rule so future contributors hit
the right primitive on the first look.

Moves:
- `utils/yaml_cache.py` -> `utils/cache/yaml.py`
- `utils/runtime_data.py` -> `utils/cache/data.py`
- `tests/unit/utils/test_yaml_cache.py` -> `tests/unit/utils/cache/test_yaml.py`
- `tests/unit/utils/test_runtime_data.py` -> `tests/unit/utils/cache/test_data.py`
- `tests/unit/utils/test_variants.py` -> `tests/unit/utils/cache/test_variants.py`

New:
- `utils/cache/__init__.py` (empty per project convention)
- `utils/cache/README.md` describing the two layers, when to reach for
  which, lifetime, test-only helpers, and design guidelines (RFC 2119
  keywords, emoji-after-headline, no self-SPOT declaration, no
  slash-in-link-text).
- `tests/unit/utils/cache/__init__.py`

Mechanical updates:
- All imports across cli/, plugins/lookup/, tests/, and roles/ rewritten
  from `utils.yaml_cache` -> `utils.cache.yaml` and
  `utils.runtime_data` -> `utils.cache.data` (40+ files).
- `REPO_ROOT` parents-index in the moved tests bumped from `parents[3]`
  to `parents[4]` to reflect the deeper nesting.
- Six broken markdown links in docs/ updated to the new module paths
  (test_markdown_links lint test stays green).
- Two test files that used the `from utils import runtime_data` form
  now use `from utils.cache import data as runtime_data` so the local
  alias remains.

Tests: 848 passed across unit + lint suites (1 pre-existing collection
error in test_host_vars.py unrelated to this change).
