already have location bindings (on_shelf or transferred) - Replace single on_shelf pre-check with unified conflict detection for both normal shelf and transit targets - Show conflict dialog listing duplicate and/or transferred items with details before any API calls are made - Prevents partial batch failures where some items succeed before a conflicting item is encountered Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
