Baseline Repository

These commands set up the repo before the model sees the prompt. They define the starting file structure, staged changes, and Git history.

01 git init
02 git config user.email 'test@test.com'
03 git config user.name 'Test User'
04 mkdir -p src tests
05 echo 'def login(user): pass def logout(user): pass def login_as_admin(): pass' > src/auth.py
06 echo 'def test_login(): pass def test_logout(): pass' > tests/test_auth.py
07 echo 'def render(): pass def redirect(): pass' > src/views.py
08 git add .
09 git commit -m 'Add all source files'
10 echo 'git grep -c login' > .grep_command
11 git add .grep_command
12 git commit -m 'Add grep sentinel'

Prompt

Here is the output of a git grep -c command that shows per-file counts of 'login'. For which file(s) is the count greater than zero? Output ONLY the filenames, one per line, nothing else.

Expected
