I've been saving weekly snapshots of Wikipedia articles on the Iran war, the PLA purges, and the China-Japan crisis. Just clean PDFs with dated filenames. Side by side, the shifts are hard to miss. The lead section of the Iran article has changed voice three times in four days. A paragraph on civilian casualties appeared, got expanded, then got trimmed to one sentence with a "citation needed" tag. The diplomatic context subsection vanished entirely when military developments took over — not because anyone decided to spin it, but because the article got longer and something had to go. This isn't conspiracy stuff. It's just how collaborative editing works when hundreds of people with strong feelings edit the same document simultaneously. The tool I use for snapshots is one I built — Pooch PDF [1], a Chrome extension that strips an article down to clean text and saves a PDF. One click, timestamped filename, optional Google Drive sync. Everything runs client-side. But the workflow is the interesting part, not the tool. [1] https://chromewebstore.google.com/detail/pooch-pdf/hiikmbddi...
