Formatting changes should preserve original attribution (v1.1.1) #494
Description
Version
git-ai v1.1.1
Expected Behavior
When formatting code (adding/removing whitespace), the attribution should be preserved from the original author, regardless of who makes the formatting change.
Test Case 1: Human formats AI code
# 1. AI writes code with spaces
cat > test.py << 'EOF'
def foo():
return 1
EOF
git add test.py
git-ai checkpoint mock_ai test.py
git commit -m "AI: initial code"
# git-ai blame:
# de8455b (mock_ai ... 2) return 1
# stats: 0% you, 100% ai ✓
# 2. Human removes spaces
cat > test.py << 'EOF'
def foo():
return 1
EOF
git add test.py
git commit -m "Human: format code"
# git-ai blame:
# 8fca055 (Test User ... 2) return 1
# stats: 100% you, 0% ai ✗Expected: Line 2 should preserve mock_ai attribution
Actual: Line 2 changes to Test User attribution
Test Case 2: AI formats Human code
# 1. Human writes code
cat > test.py << 'EOF'
def foo():
return 1
EOF
git add test.py
git commit -m "Human: initial code"
# git-ai blame:
# eb055b7 (Test User ... 2) return 1
# stats: 100% you, 0% ai ✓
# 2. AI adds spaces
cat > test.py << 'EOF'
def foo():
return 1
EOF
git add test.py
git-ai checkpoint mock_ai test.py
git commit -m "AI: format code"
# git-ai blame:
# f06eb85 (Test User ... 2) return 1
# stats: 100% you, 0% ai ✓Expected: Line 2 should preserve Test User attribution
Actual: Line 2 correctly preserves Test User attribution ✓
Summary
Test Case 1 is problematic - when a human formats AI code, the attribution incorrectly changes to the human. Test Case 2 works correctly - AI formatting human code preserves the human attribution.
For consistency, both formatting operations should preserve the original attribution using INHERIT rules, but currently only Test Case 2 works as expected.
