Mirrors the CI-green safeguards rolled out repo-wide (see screen-locker):
- scripts/check_requirements_sync.py: pre-commit hook that fails if a
package import isn't declared in requirements.txt. On rollout it caught
a real latent gap — diet_guard/_mcp.py imports pydantic but it was only
present transitively (via mcp); now declared explicitly.
- scripts/ci_mirror.sh: pre-push gate = requirements.txt-only venv
(hash-gated) running `pre-commit run --all-files` + `pytest`, replacing
the plain pytest-coverage pre-push hook.
Only the tooling files + the pydantic declaration are committed; unrelated
in-flight work in the tree is left untouched.
