Worked on the apache/dolphinscheduler repository to enhance its security documentation by introducing a dedicated Network Environment section to the security_model.md file. This update clarified the system’s security assumptions, explicitly stating that dolphinscheduler operates under the premise of a secure network and does not address internal network infiltration scenarios. The documentation was meticulously updated in both English and Chinese to ensure consistency and support for a bilingual user base. Leveraging Markdown for clear technical writing, the work focused on improving onboarding and governance alignment, demonstrating attention to detail and a methodical approach to documentation within open source project workflows.
