If a crawler reaches a JavaScript page before a snapshot exists, starting Chrome at that moment adds work to an already waiting client. RenderCache&rsquo;s alpha takes a different starting point: discover the public URLs from the sitemap, then render them before requests need the saved HTML.</p> <p>The worker queue is bounded. Missing pages get priority, refreshes are scheduled, and repeated work for a page is deduplicated. That does not make coverage automatic: an empty sitemap, a failed browser or a wrong readiness selector can leave pages without useful snapshots. The status page therefore shows what is discovered, cached, missing, queued and failing, with request-added pages reported separately.</p>
