- 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.

Eliminates the last 102 violations of test_project_root_import by
making PROJECT_ROOT in each package's __init__.py the single source
and inlining every wrapper helper.
Migrations
==========
- ~70 files: ``Path(__file__).resolve().parents[N]`` → ``from <pkg>
import PROJECT_ROOT`` (single-expression shape, scripted).
- ~12 files: two-statement helpers (``T = Path(__file__).resolve();
R = T.parents[N]``) and multi-line ``os.path.abspath(os.path.join(...
os.pardir...))`` chains rewritten by a follow-up scripted pass.
- ~20 files migrated by hand for shapes the scripts couldn't safely
rewrite (helper functions like ``_repo_root_from_test_file``,
embedded ``os.pardir`` chains, etc.).
Helpers removed (inlined to PROJECT_ROOT)
=========================================
- All ``def repo_root_from_here() / _project_root_from_here()`` and
same-shape variants in cli/ (``cli/deploy/development/{down,common,
build,deploy}.py``, ``cli/meta/categories/invokable/command.py``,
``cli/meta/applications/resolution/{combined/repo_paths,
dependencies/__main__,run_after/__main__}.py``).
- All zero-arg ``def <name>() -> Path: return PROJECT_ROOT`` helpers
(utils/invokable.py, utils/roles/resource_validation.py, cli/meta/
runtime/__init__.py, cli/meta/callorder/__main__.py, plus a dozen
test files).
- 4 ``PROJECT_ROOT = PROJECT_ROOT`` self-assignments removed from
test files where the class attribute became dead after migration.
Test-mock updates
=================
``patch.object(repo_paths, 'repo_root_from_here', return_value=ROOT)``
→ ``patch.object(repo_paths, 'PROJECT_ROOT', ROOT)`` (27 patches across
8 unit-test files); same shape for ``patch('utils.invokable._repo_root',
return_value=…)``.
Suppressions documented
=======================
5 files marked ``# nocheck: project-root-import`` for the catalog's
documented exemptions:
- 2 lints walking from a discovered glob match (<role>/templates/...)
up to its role dir, NOT the repo root.
- ``cli/validate/inventory/__main__.py`` invoked as standalone
subprocess (relative imports unavailable).
- ``plugins/filter/value_generator.py`` loaded by Ansible outside the
project package (relative imports broken).
- ``roles/test-e2e-playwright/filter_plugins/discover_playwright_roles.py``.
Bugs surfaced and fixed in the same commit
==========================================
The migration uncovered two latent role-content violations that were
silently masked by buggy ``_repo_root()`` helpers in two integration
tests (the helpers walked upward looking for marker dirs and returned
``tests/integration/`` instead of the repo root, so the tests scanned
nothing under ``roles/`` for years):
- roles/web-app-minio: extracted 6-task OIDC block into 02_oidc.yml +
``include_tasks`` (the documented "Good" pattern from
test_block_size; parsing cost is paid only when OIDC is enabled).
- roles/web-app-bluesky/tasks/01_core.yml: collapsed 3 sequential
``when: BLUESKY_WEB_ENABLED | bool`` tasks into one ``block:`` with
the guard at block level (4 → 2 occurrences, under threshold).
Two semantic-bug fixes carried alongside
========================================
- cli/core/app.py: ``cli_dir`` was previously ``parents[1]`` (= cli/),
not the repo root; rewritten to ``PROJECT_ROOT / "cli"`` to match
the variable's intent.
- cli/make/__main__.py: pre-existing bug — ``repo_root`` was actually
the ``cli/`` directory (so ``cli/Makefile`` was the search target,
which never existed). Now correctly uses PROJECT_ROOT.
- scripts/lint/sort_claude_settings.sh: invokes utils/claude/
settings_sort.py as a module (``python -m``) so its
``from . import PROJECT_ROOT`` resolves.
Verification
============
- ``ruff check .`` → clean
- ``tests.lint.repository.test_project_root_import`` → OK (102 → 0)
- 1621 unit tests → all pass
- Integration suite: 44 failures (baseline, pre-existing, none from
this commit), 1 skipped
