Global post search is more productive than group feeds: `facebook.com/search/posts?q=<query>&filters=eyJyZWNlbnRfcG9zdHM6MCI6IntcIm5hbWVcIjpcInJlY2VudF9wb3N0c1wiLFwiYXJnc1wiOlwiXCJ9In0%3D` (base64 for the recent_posts filter) covers all public groups. Long scroll scripts hit `CDP sendCommand "Runtime.evaluate" timed out after 45000ms`, so use short chunks and small batches. Scroll an inner overflow div, not the window, because document height can be tiny and `[role=article]` nodes can come back empty. Helpers on `window` vanish on navigation (`window.__sc is not a function`), and localStorage stores got wiped, so return text per query or re-inject each time. Permalinks stay hidden until hover, so harvest text first and resolve links only for candidates; output containing query strings gets `[BLOCKED: Cookie/query string data]`, so strip them.
