The tutorial pack-open alias hardcoded parent_gacha_id=99047 (the May 2026 throwback pair), so once the June rotation replaced it with 99032 the tutorial's final pack-open 400ed. Fix the identity gate by removing it: /tutorial/pack_open is now a plain alias for /pack/open with a single epilogue that advances TutorialState to 100 and emits tutorial_step=100. The tutorial gift's TICKET_MULTI item naturally scopes what the alias can open — the normal path's ticket-debit branch already consumes it, so no separate tutorial-path bypass is needed. Also drop the July-1 expiry on packs 80032/99032 so the current throwback pair stays visible. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
