# Integration test for .pre-commit-hooks.yaml as an EXTERNAL hook repo — the
# contract ADR-0014 exists to provide, and the one thing running pre-commit
# inside this repo can never exercise: `repo: local` makes pre-commit's clone
# prefix equal to the consuming repo's root, so a hook entry that only works
# because those two coincide passes here and hard-fails everywhere else.
# (It did: every argument after entry[0] resolves against the CONSUMING repo,
# so a `--config plugins/.../.vale.ini` argument gave external consumers
# `E100 [--config] Runtime error ... does not exist`, exit 2, on both Vale hooks.)
#
# The hook repo is built from the WORKING TREE, not from HEAD, so an uncommitted
# change to the manifest or the wrapper is what gets tested.
