 ## 📋 Executive Summary
 
 ObjectUI is a universal Server-Driven UI (SDUI) engine built on React + Tailwind + Shadcn. It renders JSON metadata from the @objectstack/spec protocol into pixel-perfect, accessible, and interactive enterprise interfaces.
 
-**Where We Are:** Foundation is **solid and shipping** — 35 packages, 99+ components, 5,700+ tests, 78 Storybook stories, 42/42 builds passing, ~85% protocol alignment. SpecBridge, Expression Engine, Action Engine, data binding, all view plugins (Grid/Kanban/Calendar/Gantt/Timeline/Map/Gallery), Record components, Report engine, Dashboard BI features, mobile UX, i18n (11 locales), WCAG AA accessibility, Designer Phase 1 (ViewDesigner drag-to-reorder ✅), Console through Phase 20 (L3), **AppShell Navigation Renderer** (P0.1), **Flow Designer** (P2.4), **Feed/Chatter UI** (P1.5), and **App Creation & Editing Flow** (P1.11) — all ✅ complete.

 **What Remains:** The gap to **Airtable-level UX** is primarily in:
 1. ~~**AppShell** — No dynamic navigation renderer from spec JSON (last P0 blocker)~~ ✅ Complete
