John Slack authored the Package Retention Policy Documentation for the chainguard-dev/edu repository, focusing on clarifying how long non-latest APK package versions are retained in both public and private repositories. He used Markdown and technical writing skills to align documentation with internal policy standards and ongoing Wolfi retention discussions. The work involved cross-team collaboration to ensure accuracy and consistency, updating package-model.md to reflect current practices. By providing clear guidance on retention rules, John’s documentation aimed to reduce support queries and assist sales teams. The depth of the work lay in policy alignment and knowledge transfer rather than code or bug fixes.
