<h4>Newsfeed Inline Warning Fix</h4><ul><li><strong>Fixed:</strong> PHP warning text rendering inside newsfeed posts at line 999 — $v["source_url"] undefined for newsfeed-native posts (only set for cross-module posts). Initialized source_url to empty string in the data preparation loop. Also added ?? fallbacks to source_url, post_source, btnicon, and embed template outputs.</li></ul>
