# Pre-commit hooks for todo.
#
# This repo previously used a hand-written .git/hooks/pre-commit installed by
# scripts/install_hooks.sh. It moved to the pre-commit framework when the
# 250-line file-length gate was added, so the *checks* live in one place with
# one install path.
#
# Only non-mutating checks belong here. pre-commit stashes unstaged changes
# for the duration of the run and restores them with `git apply` afterwards;
# a hook that rewrites a tracked file inside that window makes the restore
# conflict, which aborts the commit AND drops the developer's uncommitted
# edit. scripts/bump_patch_version.sh rewrites pubspec.yaml, so it stays out
# of this file and runs from the wrapper hook instead -- see
# scripts/install_hooks.sh.
#
# fail_fast so a later check cannot run after an earlier one has already
# rejected the commit.
#
# Install with:  scripts/install_hooks.sh
# The hooks are `language: system` because they are plain bash/python already
# on this machine; pre-commit must not build an isolated env for them.

      # always_run/pass_filenames rather than `files:`: a poisoned pubspec can
      # arrive by pull, merge or --no-verify, and a staged-only trigger would
      # then never look at it again for any commit that does not happen to
      # touch pubspec.yaml. The old hand-written hook checked it every time;
      # narrowing that to staged-only silently widened the hole this gate
      # exists to close.
