The native client split the feed on `<div class="post is-shown`, but `is-shown` is added by SubscribeStar's infinite-scroll JS when a post scrolls into view — present in a browser-SAVED page (what the Step-0 characterization used) but ABSENT from the raw server HTML we and gallery-dl actually fetch. So the live feed (cheunart) parsed to zero posts and raised a false SubscribeStarDriftError. Align with gallery-dl's proven `_pagination`: split on the generic `<div class="post ` (trailing space rules out the hyphenated post-content/ post-date/post-body siblings). Also mirror gallery-dl's redirect-based gating detection (/verify_subscriber, /age_confirmation_warning => auth, not drift). Regression tests: raw server markup without is-shown now parses; an age-wall redirect raises SubscribeStarAuthError. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
