- Add get_status() SQL and /api/status route; load stale state on login - Replace polling with immediate client-side stale tracking via callbacks - Amber status bar with per-item Generate buttons for sources and stacks - Pivot: add stack selector to view any dfv.stack view via Perspective - Stack views: DROP CASCADE, add id to source views, per-source balance columns - net_balance = sum(all amounts) + total_offset guarantees chase+dcard=net per row - CLAUDE.md: document correct dedup spec (within-batch duplicates always allowed) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
