• Quality Gates: Automatic PR status checks

Reporting Features

• Line-by-line analysis of covered/uncovered code
• Pull request comments with detailed coverage changes
• Historical trends and coverage evolution
• Component breakdown for focused improvement

Exclusions

The following are intelligently excluded from coverage:

• Test files (tests/)
• Documentation (docs/)
• Build scripts (scripts/)
• Package metadata (setup.py, __main__.py)
• Generated files (build/, dist/)
• Type checking imports (if TYPE_CHECKING:)
