Mirror scope.sh's is_markdown_or_rst skip-list in affected_roles.sh so a
PR that touches both a role and a doc file outside roles/<role>/ resolves
to that role only, not __ALL__. Covered by tests/integration/meta/workflows/test_diff_affected_roles.py.
Widens the cache-read lint guard from ``tests/lint/`` to every ``.py``
under ``tests/``. Integration tests show the same compounding cost
pattern (one role's compose template / nginx conf / scrape fragment
read across many shape tests) that motivated the original lint for
lint/.
Converts 91 violations across 28 test files:
- **Cache (utils.cache.files.read_text)** for project-tracked reads
and single-read tempdir fixtures, e.g. test_prometheus.py (32x),
test_keycloak_import_flow.py (11x), test_dashboard_oidc.py (3x),
test_changelog_md.py (8x), test_package_mirror.py (8x), plus
test_logging.py / test_summarize.py / test_version_updater.py /
test_get_url_retry.py / test_pull_specific_host.py.
- **Cache + UnicodeDecodeError handler** for project-walk scanners
that previously used ``errors="replace"`` / ``errors="ignore"`` to
defend against non-UTF-8 files (compose volumes, password quoting,
template image, mailu dependency, URL reachability). Wraps each
read in ``try/except (OSError, UnicodeDecodeError): continue``,
which has the same observable effect (skip undecodable files).
- **Refactor away the binary heuristic** in test_no_raw_docker.py:
``read_bytes() + b"\x00" not in raw`` becomes
``read_text() / except UnicodeDecodeError``. Same files skipped,
with cache benefit.
- **Variable extraction** in test_changelog_md.py / test_package_mirror.py
for cases where ``self.assertEqual(path.read_text(...), expected)``
exceeded ruff's 88-char limit. Ruff was wrapping the marker onto a
line outside the AST span of the read_text call.
- **Compute-from-setup** for two test methods that previously read
``self.changelog`` twice (before/after) to verify a no-op:
``before`` is now derived from the known input, dropping the first
read.
Five ``# nocheck: cache-read`` markers remain, each annotated inline
with the reason: idempotency tests where the second read must hit
disk to catch non-idempotent regressions, and tests with intermediate
``write_text`` whose subsequent read would return stale cache data.
