# pre-commit hook — blocks commits when no task is in an edit-allowed phase.
#
# Install: cp this file to .git/hooks/pre-commit && chmod +x .git/hooks/pre-commit
# Or:      ln -s ~/.automaton/scripts/git-hooks/pre-commit .git/hooks/pre-commit
#
# This is a safety net. The primary enforcement is the harness pre-edit hook.
# Pre-commit catches changes that bypassed the harness (e.g., manual edits).
