Worked on the magento/inventory repository to enhance open-source license compliance by standardizing file headers. Focused on code maintenance using PHP, the developer replaced a multi-line copyright block with a concise single-line comment and updated the year to 2025, ensuring accurate attribution and alignment with open-source standards. This change improved audit readiness and reduced compliance risk without affecting any user-facing features or altering application logic. The work was limited to header updates, maintaining code integrity while reinforcing legal defensibility. All modifications were thoroughly documented, supporting future contributions and maintaining repository hygiene through careful attention to licensing and codebase consistency.
