- Declare `__all__` in every package `__init__.py` whose `PROJECT_ROOT` is imported by its modules (163 packages), so the constant counts as exported; list every public name where the package defines more. - Empty the 15 package `__init__.py` files whose `PROJECT_ROOT` no module imports. - Declare the public API of `utils.github.variant.axes` in `__all__`, re-exports included, instead of silencing them with `noqa: F401`; the list matches the one `feature/store-i18n` already carries. - Use `import unittest.mock as mock` in `test_applications.py`, as the rest of the suite does. - Spell `_NON_PRINTABLE` in `utils/yaml_bootstrap.py` as the equivalent BMP-only positive class; it matches exactly the same 2111 code points as the old negated class across U+0000..U+10FFFF.

lookup('config', …) Path Validation 🔎
Integration tests that statically validate every lookup('config', application_id, …) (and quoted-app variants) found in role YAML and Jinja templates against the role's effective configuration.
Tests in this directory MUST only cover the four classifications of a single project-wide match stream: literal-app calls (test_literal_paths.py), variable-app calls with an existing literal path (test_variable_paths.py), ~-concatenated path expressions (test_wildcard_paths.py), and the strict per-role pass for lookup('config', application_id, …) calls inside roles/<role>/... (test_role_local_paths.py). Pure unit coverage of the lookup plugin's return values MUST live under tests/unit/python/plugins/lookup/.
The match stream is built once per process by _scan.iter_matches and shared across the four test classes; the repo-derived context (application defaults, user defaults, per-role schemas, application_id-declaring role set) comes from _scan.get_context. Validation helpers live in _validate.py. Suppression is wired through the project's noqa / nocheck grammar; the rule key is lookup-config-path (see suppression.md).
