# Public-safe leak gate for this repository.
# Runs on every commit (.githooks/pre-commit) and in CI (.github/workflows/leak-gate.yml).
# It enforces only what is safe in a PUBLIC repo: no AI/tool vendor names (outside the
# two attribution rules that discuss them), no machine-absolute paths, no em dashes.
# The private project-name scrub lives in a separate private repository, listing those
# names here would itself be the leak.

# the filename is the tool's addressing interface, function, not attribution. Root
