v2.5.1 — Reliability update. The transcript now loads automatically even when YouTube's caption API returns empty responses: the extension opens YouTube's own transcript panel and reads it, with a Retry option. Added: sign-in linking so purchased credits work inside the extension (with automatic linking when signed in on fact-scope.com), timestamped transcript with jump-to-moment chips, a multi-tab video picker, a free-checks counter, and a resizable side panel. Analysis now uses a job-based flow to prevent timeouts on long videos.
