assertTrue(x > 0) fails as "False is not true" and hides the value that failed; assertGreater(x, 0) reports the actual count. Same predicate, so pass and fail are unchanged on every input. CodeQL py/imprecise-assert on both generator tests.

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.
