Monthly work summary for 2025-10 focusing on Mastodon integration across two repositories. Delivered cross-repo Mastodon posting capabilities by integrating Mastodon posting into SocialMediaComposer and establishing a Mastodon post management flow in HGNRest. Refactored posting flow, added dev server proxy support for local testing, and prepared API-dependent functionality with required dependencies and configuration. These changes enable broader social distribution, streamline content workflows, and accelerate QA cycles across the platform.
