_fingerprint_mapping memoised digests under id(obj) while holding no
reference to obj, so CPython reused the address of a freed mapping and
served its digest for an unrelated live one. Measured 398/400 wrong
digests for short-lived mappings; in-place mutation was invisible and
the domain-index collision guard could be bypassed entirely.
Two unit tests pinned that behaviour as the contract —
test_id_cache_short_circuits_recompute asserted that mutating a dict in
place leaves its fingerprint unchanged — so the defect shipped green.
Both now assert the opposite.
build_domain_index rebuilt the whole reverse index on every lookup,
scanning every application's domains and aliases to answer one key. It
is now memoised on that fingerprint, which is only sound because of the
fix above. 4x on a 100-app payload.

Extract the csp, domains, and networks blocks out of roles/*/meta/server.yml
into dedicated meta files, each mapping to its own top-level applications key
via the recursive meta-walk:
csp: -> meta/csp.yml -> applications.<app>.csp
domains: -> meta/domains.yml -> applications.<app>.domains
networks: -> meta/networks.yml -> applications.<app>.networks
Residual nginx/proxy keys (status_codes, client_max_body_size, locations,
ip6_enabled, config_upstream_url) stay in server.yml; an emptied server.yml is
deleted. 98 server.yml -> 249 new files, 74 deleted.
- Consumers repointed applications.<app>.server.{csp,domains,networks} ->
applications.<app>.{csp,domains,networks} across templates, vars, tasks,
lookups and filters.
- Infra readers migrated: canonical_domains_map, application_domain_index,
build_ldap_role_entries, service-registry overlay discovery,
roles_with_service, and the file-based readers utils/domains/list.py +
utils/meta/scan.py (read the now-deleted server.yml directly).
- Detection + mapping: _META_TOPICS gains csp/domains/networks;
ROLE_FILE_META_{CSP,DOMAINS,NETWORKS} constants + ROLE_FILES entries.
- New self-expiring lint guard (test_server_meta_no_split_fields) fails if a
server.yml still carries a split field; auto-fails from 2026-12-28 as a
delete reminder.

TC (flake8-type-checking): typing-only imports moved into
``if TYPE_CHECKING:`` blocks across 8 source files via auto-fix
(117 hits). Reduces runtime import surface and rules out circular
imports for type-only deps. Project-wide ``from __future__ import
annotations`` (FA, already enabled) keeps annotations as strings,
so the moved imports never need to load at runtime.
N (pep8-naming): 32 hits handled.
Renames (semantic + lint):
- ``isSmallerThenMaximumBackupSize`` -> ``is_larger_than_maximum_backup_size``
(snake_case + fixes both the typo "Then -> Than" and the
semantic mismatch: the function returns ``current > maximum``)
- ``isDirectoryDeletable`` / ``deleteVersion`` /
``getAmountOfIteration`` / ``deleteIteration`` -> snake_case
- 8 test functions with ALL-CAPS env-var fragments
(``test_..._DOMAIN_PRIMARY_...`` etc.) -> snake_case
- Mock alias ``VH`` -> ``vh`` in test_host_vars.py
Exception class renames (``N818`` Error suffix):
- ``TimeLimitExceededException`` -> ``TimeLimitExceededError``
- ``AttemptException`` -> ``AttemptError``
- ``PathNotFound`` -> ``PathNotFoundError`` (propagated across
4 callers under tests/integration/lookups/config/)
- ``_ExitJson`` / ``_FailJson`` -> ``*_Error``
Refactor:
- ``METADATA = {...}`` local constant in two functions of
``plugins/filter/invokable_paths.py`` lifted to module-level
``_METADATA_KEYS``.
- ``from typing import TYPE_CHECKING`` in
``tasks/utils/migrate_meta_layout/__main__.py`` moved above
the ``sys.path.insert`` hack to satisfy E402 (collateral from
the TC auto-fix that landed it after the path mutation).
Per-file ignores in pyproject.toml for the legitimate cases the
rule cannot accept:
- ``pull-specific-host.py`` -> ``N999`` (Ansible-invoked role-level
script, hyphenated filename pinned by the surrounding stack).
- 4 matrix-deploy files -> ``N806`` for the ``include_R`` /
``raw_include_R`` round-index notation; the uppercase ``R``
here mirrors the formula in the docstring rather than naming
a constant.
- ``plugins/filter/value_generator.py`` -> ``N806`` for the
lazy-loaded class binding ``ValueGenerator =
_value_generator_cls()``, which retains the imported class
identifier per PEP 8.

Adds ``[tool.ruff.lint]`` with ``select = ["E", "F", "I", "B", "UP"]``
and ``target-version = "py311"``. ``E501`` is ignored because
``ruff format`` already reflows what it can; the remaining long lines
are unsplittable string literals / URLs.
Auto-fixed (2753 issues, behavior-preserving):
- UP006/UP035: ``List[X]`` → ``list[X]``, ``Dict[X]`` → ``dict[X]``,
``from typing import …`` redirected where superseded by builtins.
- UP045: ``Optional[X]`` → ``X | None``.
- UP010/UP009/UP015: dropped Python-2-era pragmas (``from __future__
import absolute_import, division, print_function``,
``# -*- coding: utf-8 -*-``), redundant ``open(..., "r")`` mode.
- UP004: dropped implicit ``class X(object):``.
- UP022/UP008/UP032: stdlib idiom modernization (``capture_output``,
super-call simplification, etc.).
- B905: ``zip(...)`` → ``zip(..., strict=False)`` (preserves prior
behavior; switching to ``strict=True`` is a separate semantic
choice not made here).
- I001: import-block ordering.
Hand-fixed (66 issues):
- B904 × 54: appended ``from <bound>`` (when the enclosing ``except``
binds a name) or ``from None`` (when it doesn't) so chained
exceptions stay distinguishable from errors-during-exception-
handling. Applied via a small AST-aware script that walked back to
the enclosing ``except`` clause and matched the binding.
- B017 × 4: narrowed broad ``assertRaises(Exception)`` to the actual
``AnsibleError`` / ``AnsibleFilterError`` raised by the code under
test.
- B023 × 2: bound captured loop variables via default args
(``def _record(name, *, _path_real=path_real, ...)``) so each
closure gets its own snapshot.
- B007 × 2: unused loop control variables renamed to ``_`` /
rewritten to ``.values()``.
- UP007 × 2: ``Union[X, Y]`` → ``X | Y`` (plus dropping the now-unused
``from typing import Union``).
- B018 × 1: Odoo addon manifests are bare dict expressions at module
level by design — suppressed with an inline ``# noqa: B018`` and
rationale comment.
- UP031 × 1: printf-style format → f-string.
The 65 ``# noqa: …`` markers introduced by the auto-fixer all carry
real ruff codes (``B018``, ``E402``, ``F401``, etc.), so
``test_noqa_only_ruff_codes`` stays green.
Verification
============
- ``ruff check .`` → All checks passed
- ``ruff format --check .`` → 894 files already formatted
- ``tests.lint.repository.{test_project_root_import,
test_no_direct_yaml_calls, test_noqa_only_ruff_codes}`` and
``tests.unit.utils.annotations.test_suppress`` → 20 tests OK
- 1621 unit tests → all pass
- Integration suite: 44 failures (pre-existing baseline, none from
this change), 1 skipped.
Going forward, the new rules block regressions on E (style), F
(pyflakes), I (import order), B (likely-bug patterns), and UP
(modernization to py311) for any new code.
