 ### Added
-- Added `--license-sources` (`-ls`) to copyleft inspection for filtering by license source
+- Added `--license-sources` (`-ls`) option to copyleft inspection
+  - Filter which license sources to check (component_declared, license_file, file_header, file_spdx_tag, scancode)
+  - Supports both `-ls source1 source2` and `-ls source1 -ls source2` syntax
+
+### Changed
+- Copyleft inspection now defaults to component-level licenses only (component_declared, license_file)
