OpenSSF Scorecard reports no fuzzer integration (code scanning alert
507, issue #853). tests/fuzz/_yaml_bootstrap.py is an atheris harness
that feeds arbitrary input to utils.yaml_bootstrap.load_block and fails
whenever the reader accepts a document that load_yaml_str parses
differently or rejects. That is the contract the module's docstring
states, and the existing property test only samples it. The leading
underscore keeps unittest discovery from importing it, because atheris
is only installed with the fuzz extra.
cron-security-fuzz.yml runs the harness for 15 minutes every Sunday and
on demand, on ubuntu-latest, and uploads crashing inputs as the
fuzz-crashes artifact. atheris 3.1.0 ships x86_64 manylinux wheels for
CPython 3.12 to 3.14 only, so it lives in its own `fuzz` extra and
stays out of every other install path. tests/fuzz/ is not part of
`make test`.

Keep live registry lookups out of the default make test flow.
Add a dedicated external suite, workflow, and docs so the check stays opt-in but still gates code CI when enabled.
- Move emojis after headline text (CONTRIBUTING.md, actions/, design/, tools/, tests/)
- Replace em dashes with colons, semicolons, or complete sentences throughout
- Add missing emojis to all headlines in exceptions.md, principles.md, services.md, shell.md, setup.md, pull-request.md, commit.md, act.md, docker.md, pr/README.md
- Update H1 titles to reflect renamed directories (actions/, design/)
- Fix broken relative links in workflow.md after directory moves
- Fix full-path link texts in services.md (style.css.md, javascript.js.md)
- Fix broken principles.md link to lint.md after testing/ → actions/testing/ move

Replace stale unit test README with a pointer to the canonical unit.md guide.
Add index README to tests/ and per-directory READMEs for e2e, integration,
lint, and regression — each linking to the matching docs/contributing page.
