- 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.

utils/yaml_bootstrap.py promises that load_block(text) either equals
yaml.safe_load(text) or raises BootstrapYamlError. A fuzzer comparing
both found two inputs that broke the promise:
- str.splitlines() also breaks lines at \x0b, \x0c and \x1c to \x1e,
which PyYAML's reader rejects as non-printable. "\x1e/: R" came back
as {"/": "R"}, and a non-printable character inside a comment line was
skipped with the comment.
- An indented " ---" on line 1 was taken as the document marker, while
PyYAML reads it as a plain scalar and rejects the mapping that follows.
load_block now refuses any character outside PyYAML's own printable
class before it splits lines, and takes "---" as the document marker
only at column 0. The line breaks splitlines() still honours (\r, \r\n,
NEL, LS, PS) are line breaks for PyYAML too, so splitting stays as is.
The eight inputs join STRUCTURES in the divergence test; against the
previous reader, four of them diverge and fail it.

The env generator runs on the bare bootstrap python, before any
dependency is installed. utils/distros.py reached PyYAML through
utils.cache.yaml, so `python -m cli.meta.env` died with
ModuleNotFoundError on every dev-runtime image that ships python3
without PyYAML.
utils/yaml_bootstrap.load_block reads the block-YAML subset the SPOT
files use with stdlib only. It raises BootstrapYamlError on anything it
cannot parse identically to yaml.safe_load, so meta/distros.yml fails
loud instead of drifting.
The per-line regex lint meant to guard this is gone: one hop of
indirection defeated it and it stayed green while the invariant was
broken. It is replaced by a test that runs the real generator with
every non-stdlib import blocked.
