-# JSON Compatibility Implementation Summary
-
-## Overview
-This document summarizes the low-hanging fruit implemented from the JSON_COMPATIBILITY_ANALYSIS.md document.
-
-## ✅ Completed Work
-
-### 1. Added 6 Molecular Components to JSON Registry
-
-The following components have been successfully integrated into the JSON UI system:
-
-#### Components Added:
-1. **AppBranding** - Application branding with logo, title, and subtitle
-2. **LabelWithBadge** - Label with optional badge indicator (supports variant customization)
-3. **EmptyEditorState** - Empty state display for editor contexts
-4. **LoadingFallback** - Loading message display with spinner
-5. **LoadingState** - Configurable loading state indicator (supports size variants)
-6. **NavigationGroupHeader** - Navigation group header with expand/collapse indicator
-
-### 2. Updated Type Definitions
-
-**File: `src/types/json-ui.ts`**
-- Added all 6 new component types to the `ComponentType` union type
-- Ensures full TypeScript support for the new components in JSON schemas
-
-### 3. Updated Component Registry
-
-**File: `src/lib/json-ui/component-registry.tsx`**
-- Added imports for all 6 new molecular components
-- Registered components in `componentRegistry` object
-- Added components to `customComponents` export for enhanced discoverability
-
-### 4. Created Showcase Schema
-
-**File: `src/schemas/page-schemas.ts`**
-- Created `newMoleculesShowcaseSchema` - A comprehensive demonstration page
-- Showcases each new component with realistic use cases
-- Includes data bindings and multiple variants
-- Demonstrates integration within Card layouts
-
-### 5. Enhanced JSON UI Showcase Page
-
-**File: `src/components/JSONUIShowcasePage.tsx`**
-- Added new "New Molecules" tab to the showcase
-- Integrated the new showcase schema with PageRenderer
-- Provides instant visual verification of the new components
-
-## 📊 Impact
-
-### Before:
-- JSON-compatible molecules: 3 (DataCard, SearchInput, ActionBar)
-- Total JSON components: ~60 (mostly atoms and UI primitives)
-
-### After:
-- JSON-compatible molecules: 9 (+6 new)
-- Total JSON components: ~66 (+10% increase)
-- Enhanced showcase with dedicated demonstration page
-
-## 🎯 Components Analysis Results
-
-From the original 13 "fully compatible" molecules identified:
-
-| Component | Status | Reason |
-|-----------|--------|--------|
-| AppBranding | ✅ Added | Simple props, no state |
-| LabelWithBadge | ✅ Added | Simple props, no state |
-| EmptyEditorState | ✅ Added | No props, pure display |
-| LoadingFallback | ✅ Added | Simple props, no state |
-| LoadingState | ✅ Added | Simple props, no state |
-| NavigationGroupHeader | ✅ Added | Simple props, display-only |
-| Breadcrumb | ❌ Skipped | Uses hooks (useNavigationHistory) |
-| SaveIndicator | ❌ Skipped | Internal state + useEffect |
-| LazyBarChart | ❌ Skipped | Uses async hooks (useRecharts) |
-| LazyD3BarChart | ❌ Skipped | Uses async hooks |
-| LazyLineChart | ❌ Skipped | Uses async hooks |
-| SeedDataManager | ❌ Skipped | Complex hooks + event handlers |
-| StorageSettings | ❌ Skipped | Complex state + side effects |
-
-**Success Rate: 6/13 (46%)** - Realistic assessment based on actual complexity
-
-## 📝 Usage Example
-
-Here's how to use the new components in JSON schemas:
-
-```json
-{
-  "id": "my-component",
-  "type": "AppBranding",
-  "props": {
-    "title": "My Application",
-    "subtitle": "Powered by JSON"
-  }
-}
-```
-
-```json
-{
-  "id": "label-with-count",
-  "type": "LabelWithBadge",
-  "props": {
-    "label": "Active Users",
-    "badgeVariant": "default"
-  },
-  "bindings": {
-    "badge": { "source": "userCount" }
-  }
-}
-```
-
-```json
-{
-  "id": "empty-state",
-  "type": "EmptyEditorState",
-  "props": {}
-}
-```
-
-```json
-{
-  "id": "loading",
-  "type": "LoadingState",
-  "props": {
-    "message": "Loading your data...",
-    "size": "md"
-  }
-}
-```
-
-## 🔄 Next Steps
-
-### Immediate Opportunities:
-1. **Chart Components** - Create simplified wrapper components for charts that don't require hooks
-2. **Event Binding System** - Implement the event binding system described in the analysis
-3. **State Binding System** - Implement the state binding system for interactive components
-4. **Component Wrappers** - Create JSON-friendly wrappers for complex existing components
-
-### Medium-term Goals:
-1. Add the 27 "maybe compatible" molecules with event binding support
-2. Implement computed prop transformations for dynamic component behavior
-3. Create JSON-friendly versions of the 14 organisms
-4. Build a visual component palette showing all JSON-compatible components

-
-## ✨ Key Achievements
-
-1. ✅ Successfully identified and added truly simple JSON-compatible components
-2. ✅ Maintained type safety throughout the implementation
-3. ✅ Created comprehensive demonstration with real-world examples
-4. ✅ Updated all relevant documentation
-5. ✅ Provided clear path forward for future additions
-
-## 🎉 Conclusion
-
-We successfully implemented the low-hanging fruit from the JSON compatibility analysis, adding 6 new molecular components to the JSON UI registry. These components are now fully usable in JSON schemas and have been demonstrated in the enhanced showcase page.
-
-The implementation prioritized truly simple components without complex dependencies, hooks, or state management, ensuring reliable JSON-driven rendering. The remaining "fully compatible" components were correctly identified as requiring additional infrastructure (hooks, state management) that makes them unsuitable for pure JSON configuration without wrapper components.

-# JSON UI Components Registry
-
-This document describes the JSON UI component system and lists all components that can be rendered from JSON schemas.
-
-## Overview
-
-The JSON UI system allows you to define user interfaces using JSON schemas instead of writing React code. This is useful for:
-- Dynamic UI generation
-- No-code/low-code interfaces
-- Configuration-driven UIs
-- Rapid prototyping
-
-## Quick Start
-
-### List All JSON-Compatible Components
-
-```bash
-# List all components with details
-npm run components:list
-
-# List only supported components
-npm run components:list -- --status=supported
-
-# List only planned components
-npm run components:list -- --status=planned
-
-# Output as JSON
-npm run components:list -- --format=json
-```
-
-### Using JSON UI Components
-
-Components are defined in the `ComponentType` union in `src/types/json-ui.ts` and registered in `src/lib/json-ui/component-registry.tsx`.
-
-Example JSON schema:
-
-```json
-{
-  "id": "example-page",
-  "type": "Card",
-  "props": {
-    "className": "p-6"
-  },
-  "children": [
-    {
-      "id": "heading",
-      "type": "Heading",
-      "props": {
-        "level": 2,
-        "children": "Welcome"
-      }
-    },
-    {
-      "id": "description",
-      "type": "Text",
-      "props": {
-        "children": "This is a dynamically rendered component"
-      }
-    },
-    {
-      "id": "cta",
-      "type": "Button",
-      "props": {
-        "variant": "default",
-        "children": "Get Started"

-- `scripts/list-json-components.cjs` - CLI tool to list components
-
-## Adding New Components
-
-To add a new component to the JSON UI system:
-
-1. Add the component type to `ComponentType` union in `src/types/json-ui.ts`
-2. Import and register it in `src/lib/json-ui/component-registry.tsx`
-3. Add component definition in `src/lib/component-definitions.ts`
-4. Update `json-components-registry.json` with metadata
-5. Test the component in a JSON schema
-
-### JSON Compatibility Checklist
-
-Before migrating a component, confirm all required conditions are met:
-
-- [ ] **Hooks/state are registry-safe**: hooks and internal state are acceptable when the component registry can control or expose them through JSON bindings.
-- [ ] **Bindings are defined**: any required actions, event handlers, or state bindings are already supported by the JSON UI binding system.
-- [ ] **Refactoring covered by PR**: JSON compatibility gaps should be resolved via refactoring as part of the same pull request.
-
-### Step-by-Step Migration Path
-
-Use this repeatable migration flow for planned components:
-
-1. **Update the type union** in `src/types/json-ui.ts` to include the new component type name.
-2. **Register the component** in `src/lib/json-ui/component-registry.tsx` so JSON schemas can resolve it at runtime.
-3. **Define component metadata** in `src/lib/component-definitions.ts` (defaults, prop schema, and any JSON-driven constraints).
-4. **Validate JSON schema usage** by rendering a sample schema that uses the new type.
-5. **Update registry metadata** in `json-components-registry.json` so the CLI/listing reflects the new status.
-
-## Migration Strategy
-
-Components marked as "planned" are:
-- Available in the codebase as React components
-- Not yet integrated into the JSON UI system
-- Can be migrated following the steps above
-
-Priority for migration:
-1. High-usage components
-2. Components with simple props
-3. Components with good atomic design
-4. Components without complex state management

-# JSON Expression System
-
-This document describes the JSON-friendly expression system for handling events without requiring external TypeScript functions.
-
-## Overview
-
-The JSON Expression System allows you to define dynamic behaviors entirely within JSON schemas, eliminating the need for external compute functions. This makes schemas more portable and easier to edit.
-
-## Expression Types
-
-### 1. Simple Expressions
-
-Use the `expression` field to evaluate dynamic values:
-
-```json
-{
-  "type": "set-value",
-  "target": "username",
-  "expression": "event.target.value"
-}
-```
-
-**Supported Expression Patterns:**
-
-- **Data Access**: `"data.fieldName"`, `"data.user.name"`, `"data.items.0.id"`
-  - Access any field in the data context
-  - Supports nested objects using dot notation
-
-- **Event Access**: `"event.target.value"`, `"event.key"`, `"event.type"`
-  - Access event properties
-  - Commonly used for form inputs
-
-- **Date Operations**: `"Date.now()"`
-  - Get current timestamp
-  - Useful for creating unique IDs
-
-- **Literals**: `42`, `"hello"`, `true`, `false`, `null`
-  - Direct values
-
-### 2. Value Templates
-
-Use the `valueTemplate` field to create objects with dynamic values:
-
-```json
-{
-  "type": "create",
-  "target": "todos",
-  "valueTemplate": {
-    "id": "Date.now()",
-    "text": "data.newTodo",
-    "completed": false,
-    "createdBy": "data.currentUser"
-  }
-}
-```
-
-**Template Behavior:**
-- String values starting with `"data."` or `"event."` are evaluated as expressions
-- Other values are used as-is
-- Perfect for creating new objects with dynamic fields
-
-### 3. Static Values
-
-Use the `value` field for static values:
-
-```json
-{
-  "type": "set-value",
-  "target": "isLoading",
-  "value": false
-}
-```
-
-## Action Types with Expression Support
-
-### set-value
-Update a data source with a new value.
-
-**With Expression:**
-```json
-{
-  "id": "update-filter",
-  "type": "set-value",
-  "target": "searchQuery",
-  "expression": "event.target.value"
-}
-```
-
-**With Static Value:**
-```json
-{
-  "id": "reset-filter",
-  "type": "set-value",
-  "target": "searchQuery",
-  "value": ""
-}
-```
-
-### create
-Add a new item to an array data source.
-
-**With Value Template:**
-```json
-{
-  "id": "add-todo",
-  "type": "create",
-  "target": "todos",
-  "valueTemplate": {
-    "id": "Date.now()",
-    "text": "data.newTodo",
-    "completed": false
-  }
-}
-```
-
-### update
-Update an existing value (similar to set-value).
-
-```json
-{
-  "id": "update-count",
-  "type": "update",
-  "target": "viewCount",
-  "expression": "data.viewCount + 1"
-}
-```
-
-**Note:** Arithmetic expressions are not yet supported. Use `increment` action type instead.
-
-### delete
-Remove an item from an array.
-
-```json
-{
-  "id": "remove-todo",
-  "type": "delete",
-  "target": "todos",
-  "path": "id",
-  "expression": "data.selectedId"
-}
-```
-
-## Common Patterns
-
-### 1. Input Field Updates
-
-```json
-{
-  "id": "name-input",
-  "type": "Input",
-  "bindings": {
-    "value": { "source": "userName" }
-  },
-  "events": [
-    {
-      "event": "change",
-      "actions": [
-        {
-          "type": "set-value",
-          "target": "userName",
-          "expression": "event.target.value"
-        }
-      ]
-    }
-  ]
-}
-```
-
-### 2. Creating Objects with IDs
-
-```json
-{
-  "type": "create",
-  "target": "items",
-  "valueTemplate": {
-    "id": "Date.now()",
-    "name": "data.newItemName",
-    "status": "pending",
-    "createdAt": "Date.now()"
-  }
-}
-```
-
-### 3. Resetting Forms
-
-```json
-{
-  "event": "click",
-  "actions": [
-    {
-      "type": "set-value",
-      "target": "formField1",
-      "value": ""
-    },
-    {
-      "type": "set-value",
-      "target": "formField2",
-      "value": ""
-    }
-  ]
-}
-```
-
-### 4. Success Notifications
-
-```json
-{
-  "type": "show-toast",
-  "message": "Item saved successfully!",
-  "variant": "success"
-}
-```
-
-## Backward Compatibility
-
-The system maintains backward compatibility with the legacy `compute` function approach:
-
-**Legacy (still supported):**
-```json
-{
-  "type": "set-value",
-  "target": "userName",
-  "compute": "updateUserName"
-}
-```
-
-**New (preferred):**
-```json
-{
-  "type": "set-value",
-  "target": "userName",
-  "expression": "event.target.value"
-}
-```
-
-The schema loader will automatically hydrate legacy `compute` references while new schemas can use pure JSON expressions.
-
-## Limitations
-
-Current limitations (may be addressed in future updates):
-
-1. **No Arithmetic**: Cannot do `"data.count + 1"` - use `increment` action type instead
-2. **No String Concatenation**: Cannot do `"Hello " + data.name` - use template strings in future
-3. **No Complex Logic**: Cannot do nested conditionals or loops
-4. **No Custom Functions**: Cannot call user-defined functions
-
-For complex logic, you can still use the legacy `compute` functions or create custom action types.
-
-## Migration Guide
-
-### From Compute Functions to Expressions
-
-**Before:**
-```typescript
-// In compute-functions.ts
-export const updateNewTodo = (data: any, event: any) => event.target.value
-
-// In schema
-{
-  "type": "set-value",
-  "target": "newTodo",
-  "compute": "updateNewTodo"
-}
-```
-
-**After:**
-```json
-{
-  "type": "set-value",
-  "target": "newTodo",
-  "expression": "event.target.value"
-}
-```
-
-**Before:**
-```typescript
-// In compute-functions.ts
-export const computeAddTodo = (data: any) => ({
-  id: Date.now(),
-  text: data.newTodo,
-  completed: false,
-})
-
-// In schema
-{
-  "type": "create",
-  "target": "todos",
-  "compute": "computeAddTodo"
-}
-```
-
-**After:**
-```json
-{
-  "type": "create",
-  "target": "todos",
-  "valueTemplate": {
-    "id": "Date.now()",
-    "text": "data.newTodo",
-    "completed": false
-  }
-}
-```
-
-## Examples
-
-See the example schemas:
-- `/src/schemas/todo-list-json.json` - Pure JSON event system example
-- `/src/schemas/todo-list.json` - Legacy compute function approach
-
-## Future Enhancements
-
-Planned features for future versions:
-
-1. **Arithmetic Expressions**: `"data.count + 1"`
-2. **String Templates**: `"Hello ${data.userName}"`
-3. **Comparison Operators**: `"data.age > 18"`
-4. **Logical Operators**: `"data.isActive && data.isVerified"`
-5. **Array Operations**: `"data.items.filter(...)"`, `"data.items.map(...)"`
-6. **String Methods**: `"data.text.trim()"`, `"data.email.toLowerCase()"`
-
-For now, use the legacy `compute` functions for these complex scenarios.

+# Review: maybe-json-compatible components and binding gaps
+
+## Scope
+Components still marked `maybe-json-compatible` were reviewed for missing event/state bindings that would need to be exposed to the JSON UI system. This list mirrors the registry entries that currently sit in that status. Each component below is annotated with the missing bindings that should be mapped to JSON events (`events`) or data bindings (`bindings`/`dataBinding`).
+
+## Component-by-component binding gaps
+
+### Dialogs and editor flows
+- **CodeExplanationDialog**: needs JSON bindings for `open` and `onOpenChange`, plus data bindings for `fileName`, `explanation`, and `isLoading` so schemas can control dialog visibility and content. These are currently prop-only. 
+- **ComponentBindingDialog**: needs JSON bindings for `open`, `component`, and `dataSources`, plus event bindings for `onOpenChange` and `onSave`. This dialog also pipes `onChange` updates through `BindingEditor`, which should map to JSON actions when used from schemas.
+- **DataSourceEditorDialog**: needs JSON bindings for `open`, `dataSource`, `allDataSources`, plus event bindings for `onOpenChange` and `onSave`. Internally, field updates (e.g., `updateField`, dependency add/remove) are not yet exposed as JSON actions.
+- **TreeFormDialog**: needs JSON bindings for `open`, `name`, `treeDescription`, plus event bindings for `onNameChange`, `onDescriptionChange`, `onOpenChange`, and `onSubmit`.
+
+### Selection and list management
+- **FileTabs**: needs JSON bindings for `files` and `activeFileId`, plus event bindings for `onFileSelect` and `onFileClose`.
+- **NavigationItem**: needs JSON binding for `isActive`/`badge` and event binding for `onClick`.
+- **NavigationMenu**: relies on internal `expandedGroups` state and a set of callbacks (`onTabChange`, `onToggleGroup`, `onItemHover`, `onItemLeave`). These should be exposed as JSON data bindings and events to support JSON-driven navigation and hover-driven actions (e.g., preloading routes).
+- **TreeCard**: needs event bindings for `onSelect`, `onEdit`, `onDuplicate`, and `onDelete` plus data bindings for `isSelected`/`disableDelete` to allow schema-driven selection state.
+- **TreeListHeader**: needs event bindings for `onCreateNew`, `onImportJson`, and `onExportJson`, with `hasSelectedTree` coming from data bindings.
+- **TreeListPanel**: orchestrates tree selection and CRUD; bindings are needed for `trees`, `selectedTreeId`, and event callbacks (`onTreeSelect`, `onTreeEdit`, `onTreeDuplicate`, `onTreeDelete`, `onCreateNew`, `onImportJson`, `onExportJson`).
+
+### Data source management
+- **DataSourceCard**: requires event bindings for `onEdit` and `onDelete`, plus data bindings for `dataSource` and `dependents`.
+- **DataSourceManager**: uses local state for `editingSource` and dialog visibility while exposing `onChange` externally. Needs JSON bindings for `dataSources` and events for `onAdd`, `onEdit`, `onDelete`, `onSave` (mapped to create/update/delete actions) plus ability to toggle dialog state from JSON.
+
+### Editor UI and property panels
+- **BindingEditor**: should expose `bindings`, `dataSources`, and `availableProps` through data bindings plus event bindings for `onChange` when bindings are added/removed.
+- **CanvasRenderer**: needs JSON events for `onSelect`, `onHover`, `onHoverEnd`, `onDragOver`, `onDragLeave`, and `onDrop`, and data bindings for `selectedId`, `hoveredId`, `draggedOverId`, and `dropPosition` so drag/hover state can live in JSON data.
+- **ComponentPalette**: should expose `onDragStart` via JSON events, and optionally a binding for the active tab/category if schemas should control which tab is open.
+- **ComponentTree**: relies on internal expansion state (`expandedIds`) and emits `onSelect`, `onHover`, `onDragStart`, `onDrop`, etc. Those should be JSON event bindings plus data bindings for expansion and selection state.
+- **PropertyEditor**: needs event bindings for `onUpdate` and `onDelete`, with the selected `component` coming from JSON data.
+- **SchemaEditorCanvas**: mirrors `CanvasRenderer`; bindings needed for all selection/hover/drag data and events.
+- **SchemaEditorLayout**: orchestrates `onImport`, `onExport`, `onCopy`, `onPreview`, `onClear`, plus component drag events and selection state. These should map to JSON action handlers.
+- **SchemaEditorPropertiesPanel**: inherits `ComponentTree` and `PropertyEditor` events; all selection/drag/update/delete events should be exposed in JSON.
+- **SchemaEditorSidebar**: needs JSON event binding for `onDragStart` from the component palette.
+- **SchemaEditorToolbar**: needs JSON event bindings for `onImport`, `onExport`, `onCopy`, `onPreview`, and `onClear`.
+
+### Search and toolbar interactions
+- **ActionBar**: actions array needs JSON event bindings for each `onClick` with optional `disabled`/`variant` driven by bindings.
+- **EditorActions**: needs JSON event bindings for `onExplain` and `onImprove`.
+- **EditorToolbar**: needs bindings for `openFiles` and `activeFileId`, plus events for file select/close and explain/improve actions.
+- **SearchBar**: needs binding for `value` plus event binding for `onChange`/clear.
+- **SearchInput**: needs binding for `value` plus event bindings for `onChange` and `onClear`.
+- **ToolbarButton** and **ToolbarActions**: need JSON event bindings for their `onClick` handlers.
+
+### Monaco editor integrations
+- **LazyInlineMonacoEditor**: needs data binding for `value` and event binding for `onChange`.
+- **LazyMonacoEditor**/**MonacoEditorPanel**: same binding as above (value/content and change events).
+
+### Mostly presentational components (no missing event/state bindings beyond data)
+These components are largely render-only and should work with basic `props`/`bindings` without extra event wiring: **SchemaCodeViewer**, **EmptyCanvasState**, **EmptyState**, **SchemaEditorStatusBar**, **StatCard**, **DataCard**, **PageHeaderContent**, **AppHeader** (except for the actions passed into the toolbar components), **JSONUIShowcase** (internal demo state).
+
+## Mapping missing bindings to the JSON action + expression systems
+
+The JSON UI system already supports `events` for action execution and `bindings`/`dataBinding` for state. The following mappings show how each missing binding should be wired.
+
+### 1) Dialog open/close control
+**Bindings:** `open` state stored in a data source.
+
+```json
+{
+  "id": "code-explain-dialog",
+  "type": "CodeExplanationDialog",
+  "bindings": {
+    "open": { "source": "uiState", "path": "dialogs.codeExplainOpen" },
+    "fileName": { "source": "editor", "path": "activeFile.name" },
+    "explanation": { "source": "ai", "path": "explanation" },
+    "isLoading": { "source": "ai", "path": "loading" }
+  },
+  "events": {
+    "onOpenChange": {
+      "actions": [
+        {
+          "id": "toggle-code-explain",
+          "type": "set-value",
+          "target": "uiState.dialogs.codeExplainOpen",
+          "expression": "event"
+        }
+      ]
+    }
+  }
+}
+```
+
+**Why:** `onOpenChange` provides a boolean; the JSON action `set-value` with an expression is a direct mapping for controlled dialog visibility.
+
+### 2) Input value + change events (SearchBar/SearchInput/TreeFormDialog)
+**Bindings:** `value` and `onChange` mapped to `set-value` with `event.target.value`.
+
+```json
+{
+  "id": "search-input",
+  "type": "SearchInput",
+  "bindings": {
+    "value": { "source": "filters", "path": "query" }
+  },
+  "events": {
+    "onChange": {
+      "actions": [
+        {
+          "id": "update-search-query",
+          "type": "set-value",
+          "target": "filters.query",
+          "expression": "event.target.value"
+        }
+      ]
+    },
+    "onClear": {
+      "actions": [
+        {
+          "id": "clear-search-query",
+          "type": "set-value",
+          "target": "filters.query",
+          "value": ""
+        }
+      ]
+    }
+  }
+}
+```
+
+**Why:** `event.target.value` is supported by the JSON expression system, allowing direct mapping from inputs.
+
+### 3) List selection (FileTabs, NavigationMenu, TreeListPanel)
+**Bindings:** selection ID stored in state, `onClick` mapped to `set-value` with a static or computed value.
+
+```json
+{
+  "id": "file-tabs",
+  "type": "FileTabs",
+  "bindings": {
+    "files": { "source": "editor", "path": "openFiles" },
+    "activeFileId": { "source": "editor", "path": "activeFileId" }
+  },
+  "events": {
+    "onFileSelect": {
+      "actions": [
+        {
+          "id": "select-file",
+          "type": "set-value",
+          "target": "editor.activeFileId",
+          "expression": "event"
+        }
+      ]
+    },
+    "onFileClose": {
+      "actions": [
+        {
+          "id": "close-file",
+          "type": "custom",
+          "params": { "fileId": "event" }
+        }
+      ]
+    }
+  }
+}
+```
+
+**Why:** selection changes are simple state updates. More complex close behavior can map to a `custom` action if it needs side effects.
+
+### 4) Toolbar and button actions (ActionBar, ToolbarActions, EditorActions)
+**Bindings:** each `onClick` maps to a JSON action list.
+
+```json
+{
+  "id": "schema-toolbar",
+  "type": "SchemaEditorToolbar",
+  "events": {
+    "onImport": { "actions": [{ "id": "import-json", "type": "custom" }] },
+    "onExport": { "actions": [{ "id": "export-json", "type": "custom" }] },
+    "onCopy": { "actions": [{ "id": "copy-json", "type": "custom" }] },
+    "onPreview": { "actions": [{ "id": "open-preview", "type": "open-dialog", "target": "uiState", "path": "preview" }] },
+    "onClear": { "actions": [{ "id": "clear-schema", "type": "set-value", "target": "schema.components", "value": [] }] }
+  }
+}
+```
+
+**Why:** these are pure event triggers; `custom` actions cover app-specific flows that aren’t part of the built-in action types.
+
+**Dialog storage convention:** `open-dialog`/`close-dialog` actions store booleans in `uiState.dialogs.<dialogId>`. Use `target` for the data source (typically `uiState`) and `path` for the dialog id.
+
+### 5) Drag-and-drop/hover state (CanvasRenderer, ComponentTree)
+**Bindings:** IDs and `dropPosition` stored in data; events mapped to custom actions for editor logic.
+
+```json
+{
+  "id": "canvas",
+  "type": "CanvasRenderer",
+  "bindings": {
+    "selectedId": { "source": "editor", "path": "selectedId" },
+    "hoveredId": { "source": "editor", "path": "hoveredId" },
+    "draggedOverId": { "source": "editor", "path": "draggedOverId" },
+    "dropPosition": { "source": "editor", "path": "dropPosition" }
+  },
+  "events": {
+    "onSelect": { "actions": [{ "id": "select-node", "type": "set-value", "target": "editor.selectedId", "expression": "event" }] },
+    "onHover": { "actions": [{ "id": "hover-node", "type": "set-value", "target": "editor.hoveredId", "expression": "event" }] },
+    "onHoverEnd": { "actions": [{ "id": "clear-hover", "type": "set-value", "target": "editor.hoveredId", "value": null }] },
+    "onDragOver": { "actions": [{ "id": "drag-over", "type": "custom", "params": { "targetId": "event" } }] },
+    "onDrop": { "actions": [{ "id": "drop-node", "type": "custom", "params": { "targetId": "event" } }] }
+  }
+}
+```
+
+**Why:** drag/drop handlers need richer logic, so `custom` actions are the safest mapping until more JSON-native drag actions exist.
+
+### 6) Data source CRUD (DataSourceManager/DataSourceCard)
+**Bindings:** data sources array stored in JSON data; CRUD mapped to `create`/`update`/`delete` actions where possible.
+
+```json
+{
+  "id": "data-sources",
+  "type": "DataSourceManager",
+  "bindings": {
+    "dataSources": { "source": "schema", "path": "dataSources" }
+  },
+  "events": {
+    "onAdd": {
+      "actions": [
+        {
+          "id": "add-source",
+          "type": "create",
+          "target": "schema.dataSources",
+          "valueTemplate": {
+            "id": "Date.now()",
+            "type": "event.type",
+            "value": ""
+          }
+        }
+      ]
+    },
+    "onEdit": {
+      "actions": [
+        { "id": "open-source-editor", "type": "open-dialog", "target": "uiState", "path": "dataSourceEditor" }
+      ]
+    },
+    "onDelete": {
+      "actions": [
+        { "id": "delete-source", "type": "delete", "target": "schema.dataSources", "path": "id", "expression": "event" }
+      ]
+    },
+    "onSave": {
+      "actions": [
+        { "id": "update-source", "type": "update", "target": "schema.dataSources", "expression": "event" }
+      ]
+    }
+  }
+}
+```
+
+**Why:** CRUD aligns with the action schema (`create`, `update`, `delete`) and can use expressions/value templates to shape payloads.
+
+## Prioritized binding additions (with example schemas)
+
+1) **Dialog visibility + save/cancel actions** (CodeExplanationDialog, ComponentBindingDialog, DataSourceEditorDialog, TreeFormDialog)
+   - **Why priority:** unlocks core UI flows (open/close/save) and ties dialogs to JSON actions.
+   - **Example schema:** see “Dialog open/close control” above.
+
+2) **Input value + change events** (SearchBar, SearchInput, TreeFormDialog)
+   - **Why priority:** essential for text filtering, search, and form editing in JSON-driven flows.
+   - **Example schema:** see “Input value + change events.”
+
+3) **Selection and navigation events** (FileTabs, NavigationItem/Menu, TreeListPanel, TreeCard)
+   - **Why priority:** these are the primary navigation and selection surfaces in the editor UI.
+   - **Example schema:** see “List selection.”
+
+4) **Toolbar/button action wiring** (SchemaEditorToolbar, ToolbarActions, EditorActions, ActionBar)
+   - **Why priority:** these buttons trigger important workflows (import/export, AI tools, preview).
+   - **Example schema:** see “Toolbar and button actions.”
+
+5) **Drag-and-drop/hover orchestration** (CanvasRenderer, ComponentTree, ComponentPalette)
+   - **Why priority:** required for schema editing UI; may need `custom` actions for editor logic.
+   - **Example schema:** see “Drag-and-drop/hover state.”
+
+6) **Data source CRUD flows** (DataSourceManager, DataSourceCard)
+   - **Why priority:** CRUD should map to built-in JSON actions to avoid bespoke handlers.
+   - **Example schema:** see “Data source CRUD.”

+
+## Analysis of 68 React Components
+
+After analyzing all 68 organism and molecule components, here's what can be converted to JSON:
+
+### Categories
+
+#### ✅ Fully Convertible to JSON (48 components)
+
+These are presentational components with props, conditional rendering, and simple event handlers:
+
+**Molecules (35):**
+1. `LabelWithBadge` - ✅ Converted
+2. `LoadingState` - ✅ Converted
+3. `SaveIndicator` - ✅ Converted (computed sources replace hook)

+
+**Organisms (13):**
+1. `AppHeader` - ✅ Already converted
+2. `EmptyCanvasState` - ✅ Already converted
+3. `NavigationMenu` - ✅ Already converted

+
+#### ⚠️ Needs Wrapper (Complex Hooks) (12 components)
+
+These use hooks but the hook logic can be extracted to data sources or remain in a thin wrapper:
+
+**Molecules (10):**
+1. `BindingEditor` - Form with `useForm` hook → Extract to form state
+2. `ComponentBindingDialog` - Dialog with `useForm` → Extract to form state
+3. `DataSourceEditorDialog` - Complex form + validation → Wrapper + JSON form
+4. `PropertyEditor` - Dynamic form generation → Computed source for fields
+5. `ComponentPalette` - Search + filter → Computed source
+6. `CanvasRenderer` - Recursive rendering → Could be JSON with loop support
+7. `ComponentTree` - Tree state + drag/drop → State machine in JSON
+8. `ComponentTreeNodes` - Recursive nodes → Loop construct
+9. `CodeExplanationDialog` - Dialog + API call → Dialog JSON + API action
+10. `DataSourceCard` - Card with actions + state → Separate state, JSON layout
+
+**Organisms (2):**
+1. `DataSourceManager` - Complex CRUD + hook → Extract `useDataSourceManager` logic
+2. `JSONUIShowcase` - Examples display → Convert examples to JSON schema
+
+#### ❌ Must Stay React (8 components)
+
+These have imperative APIs, complex recursion, or third-party integration:
+
+**Molecules (6):**
+1. `LazyMonacoEditor` - Monaco integration (refs, imperative API)
+2. `LazyInlineMonacoEditor` - Monaco integration
+3. `MonacoEditorPanel` - Monaco wrapper
+4. `LazyBarChart` - Recharts integration
+5. `LazyLineChart` - Recharts integration
+6. `LazyD3BarChart` - D3.js integration (imperative DOM manipulation)
+
+**Organisms (2):**
+1. `SchemaEditor` - Complex editor with drag-drop, undo/redo state machine
+2. `DataBindingDesigner` - Visual flow editor with canvas manipulation
+
+## Conversion Statistics
+
+| Category | Count | Percentage |
+|----------|-------|------------|
+| ✅ Fully Convertible | 48 | 71% |
+| ⚠️ Needs Wrapper | 12 | 18% |
+| ❌ Must Stay React | 8 | 11% |
+| **Total** | **68** | **100%** |
+
+## Key Insights
+
+### 1. Most Components Are Presentational
+71% of components are pure presentation + simple logic that JSON can handle with:
+- Data binding
+- Computed sources
+- Conditional rendering
+- Event actions
+- Loops (for lists)
+
+### 2. Hooks Aren't a Blocker
+Even components with hooks like `useSaveIndicator` can be converted:
+- Time-based logic → Computed sources with polling
+- Form state → Form data sources
+- Local UI state → Page-level state
+
+### 3. True Blockers
+Only 8 components (11%) genuinely need React:
+- Third-party library integrations (Monaco, D3, Recharts)
+- Complex state machines (drag-drop, undo/redo)
+- Imperative DOM manipulation
+- Recursive algorithms (though loops might handle some)
+
+### 4. Wrapper Pattern
+The 12 "needs wrapper" components can have thin React wrappers that:
+- Extract hooks to data source utilities
+- Convert to JSON-configurable components
+- Keep complex logic centralized
+
+Example:
+```tsx
+// Thin wrapper
+export function FormDialogWrapper({ schema, onSubmit }) {
+  const form = useForm()
+  return <JSONDialog schema={schema} formState={form} onSubmit={onSubmit} />
+}
+```
+
+```json
+// JSON configures it
+{
+  "type": "FormDialogWrapper",
+  "props": {
+    "schema": { "$ref": "./schemas/user-form.json" }
+  }
+}
+```
+
+## Recommended Conversion Priority
+
+### Phase 1: Low-Hanging Fruit (35 molecules)
+Convert all presentational molecules that are just composition:
+- AppBranding, ActionBar, ToolbarButton, etc.
+- **Impact**: Eliminate 51% of React components
+
+### Phase 2: Organisms (13)
+Convert layout organisms:
+- TreeListPanel, SchemaCodeViewer, etc.
+- **Impact**: Eliminate 70% of React components
+
+### Phase 3: Extract Hooks (10 molecules)
+Create data source utilities and convert:
+- BindingEditor, ComponentPalette, etc.
+- **Impact**: Eliminate 85% of React components
+
+### Phase 4: Wrappers (2 organisms)
+Create thin wrappers for complex components:
+- DataSourceManager, JSONUIShowcase
+- **Impact**: 89% conversion
+
+### Final State
+- **8 React components** (third-party integrations + complex editors)
+- **60 JSON components** (89% of current React code)
+- **100% JSON page definitions** (already achieved)
+
+## Implementation Patterns
+
+### Pattern 1: Simple Conversion
+```tsx
+// React
+export function LabelWithBadge({ label, badge }) {
+  return (
+    <Flex>
+      <Text>{label}</Text>
+      {badge && <Badge>{badge}</Badge>}
+    </Flex>
+  )
+}
+```
+
+```json
+// JSON
+{
+  "type": "div",
+  "className": "flex gap-2",
+  "children": [
+    { "type": "Text", "dataBinding": { "children": { "source": "label" } } },
+    {
+      "type": "Badge",
+      "conditional": { "source": "badge", "operator": "truthy" },
+      "dataBinding": { "children": { "source": "badge" } }
+    }
+  ]
+}
+```
+
+### Pattern 2: Hook Extraction
+```tsx
+// React (before)
+export function SaveIndicator({ lastSaved }) {
+  const { timeAgo, isRecent } = useSaveIndicator(lastSaved)
+  return <div>{isRecent ? 'Saved' : timeAgo}</div>
+}
+```
+
+```json
+// JSON (after) - hook logic → computed source
+{
+  "dataSources": [
+    {
+      "id": "isRecent",
+      "type": "computed",
+      "compute": "(data) => Date.now() - data.lastSaved < 3000"
+    }
+  ],
+  "type": "div",
+  "dataBinding": {
+    "children": {
+      "source": "isRecent",
+      "transform": "(isRecent, data) => isRecent ? 'Saved' : data.timeAgo"
+    }
+  }
+}
+```
+
+### Pattern 3: Wrapper for Complex Logic
+```tsx
+// Thin React wrapper
+export function DataSourceManagerWrapper(props) {
+  const manager = useDataSourceManager(props.dataSources)
+  return <JSONComponent schema={schema} data={manager} />
+}
+```
+
+## Next Steps
+
+1. ✅ Convert 35 simple molecules to JSON
+2. ✅ Convert 13 layout organisms to JSON
+3. ⚠️ Extract hooks to utilities for 10 components
+4. ⚠️ Create wrappers for 2 complex organisms
+5. ❌ Keep 8 third-party integrations as React
+
+**Target: 60/68 components in JSON (89% conversion)**

+# Hybrid Architecture: JSON + React
+
+## The Power of Both Worlds
+
+This platform uses a **hybrid architecture** where JSON handles declarative UI composition while React provides the imperative implementation layer. This gives you the best of both worlds:
+
+- **JSON** for structure, composition, and configuration
+- **React** for complex logic, hooks, events, and interactivity
+
+## What JSON Can't (and Shouldn't) Replace
+
+### 1. Hooks
+React hooks manage complex stateful logic that can't be represented declaratively:
+
+```tsx
+// ❌ Cannot be JSON
+function useDataSourceManager(dataSources: DataSource[]) {
+  const [localSources, setLocalSources] = useState(dataSources)
+  const [editingSource, setEditingSource] = useState<DataSource | null>(null)
+
+  useEffect(() => {
+    // Sync with external API
+    syncDataSources(localSources)
+  }, [localSources])
+
+  const getDependents = useCallback((id: string) => {
+    return localSources.filter(ds => ds.dependencies?.includes(id))
+  }, [localSources])
+
+  return { localSources, editingSource, getDependents, ... }
+}
+```
+
+**Why React?** Hooks encapsulate complex imperative logic: side effects, memoization, refs, context. JSON is declarative and can't express these patterns.
+
+### 2. Event Handlers with Complex Logic
+Simple actions work in JSON, but complex event handling needs code:
+
+```tsx
+// ✅ Simple actions in JSON
+{
+  "events": [{
+    "event": "onClick",
+    "actions": [
+      { "type": "setState", "target": "count", "value": 1 },
+      { "type": "toast", "title": "Clicked!" }
+    ]
+  }]
+}
+
+// ❌ Complex logic needs React
+function handleFileUpload(event: React.ChangeEvent<HTMLInputElement>) {
+  const file = event.target.files?.[0]
+  if (!file) return
+
+  // Validate file type
+  const validTypes = ['image/png', 'image/jpeg', 'image/svg+xml']
+  if (!validTypes.includes(file.type)) {
+    toast.error('Invalid file type')
+    return
+  }
+
+  // Check file size
+  const maxSize = 5 * 1024 * 1024 // 5MB
+  if (file.size > maxSize) {
+    toast.error('File too large')
+    return
+  }
+
+  // Convert to base64, compress, upload
+  compressImage(file).then(compressed => {
+    uploadToServer(compressed).then(url => {
+      updateState({ faviconUrl: url })
+      toast.success('Uploaded!')
+    })
+  })
+}
+```
+
+**Why React?** Branching logic, async operations, error handling, file processing. JSON actions are linear and synchronous.
+
+### 3. Classes and Interfaces
+Type systems and OOP patterns require TypeScript:
+
+```tsx
+// ❌ Cannot be JSON
+export interface DataSource {
+  id: string
+  type: DataSourceType
+  dependencies?: string[]
+  compute?: string
+}
+
+export class ThemeManager {
+  private themes: Map<string, Theme>
+  private listeners: Set<ThemeListener>
+
+  constructor(initialThemes: Theme[]) {
+    this.themes = new Map(initialThemes.map(t => [t.id, t]))
+    this.listeners = new Set()
+  }
+
+  applyTheme(themeId: string): void {
+    const theme = this.themes.get(themeId)
+    if (!theme) throw new Error(`Theme ${themeId} not found`)
+
+    // Apply CSS variables
+    Object.entries(theme.colors).forEach(([key, value]) => {
+      document.documentElement.style.setProperty(`--${key}`, value)
+    })
+
+    // Notify listeners
+    this.listeners.forEach(listener => listener.onThemeChange(theme))
+  }
+}
+```
+
+**Why React/TS?** Type safety, encapsulation, methods, private state. JSON is just data.
+
+### 4. Complex Rendering Logic
+Conditional rendering with complex business rules:
+
+```tsx
+// ❌ Cannot be JSON
+function ComponentTree({ components }: ComponentTreeProps) {
+  const renderNode = (component: Component, depth: number): ReactNode => {
+    const hasChildren = component.children && component.children.length > 0
+    const isExpanded = expandedNodes.has(component.id)
+    const isDragging = draggedNode === component.id
+    const isDropTarget = dropTarget === component.id
+
+    // Determine visual state
+    const className = cn(
+      'tree-node',
+      { 'tree-node--expanded': isExpanded },
+      { 'tree-node--dragging': isDragging },
+      { 'tree-node--drop-target': isDropTarget && canDrop(component) }
+    )
+
+    return (
+      <div
+        className={className}
+        style={{ paddingLeft: `${depth * 20}px` }}
+        onDragStart={() => handleDragStart(component)}
+        onDragOver={(e) => handleDragOver(e, component)}
+        onDrop={() => handleDrop(component)}
+      >
+        {/* Recursive rendering */}
+        {hasChildren && isExpanded && (
+          <div className="tree-children">
+            {component.children.map(child =>
+              renderNode(child, depth + 1)
+            )}
+          </div>
+        )}
+      </div>
+    )
+  }
+
+  return <div className="tree-root">{components.map(c => renderNode(c, 0))}</div>
+}
+```
+
+**Why React?** Recursion, dynamic styling, drag-and-drop state, event coordination. JSON can't express recursive algorithms.
+
+### 5. Third-Party Integrations
+Libraries with imperative APIs need wrapper components:
+
+```tsx
+// ❌ Cannot be JSON
+import MonacoEditor from '@monaco-editor/react'
+
+export function LazyMonacoEditor({ value, onChange, language }: EditorProps) {
+  const editorRef = useRef<monaco.editor.IStandaloneCodeEditor>()
+  const [isValid, setIsValid] = useState(true)
+
+  useEffect(() => {
+    // Configure Monaco
+    monaco.languages.typescript.typescriptDefaults.setCompilerOptions({
+      target: monaco.languages.typescript.ScriptTarget.ES2020,
+      allowNonTsExtensions: true,
+      moduleResolution: monaco.languages.typescript.ModuleResolutionKind.NodeJs,
+    })
+
+    // Add custom validation
+    monaco.editor.onDidChangeMarkers(([uri]) => {
+      const markers = monaco.editor.getModelMarkers({ resource: uri })
+      setIsValid(markers.filter(m => m.severity === 8).length === 0)
+    })
+  }, [])
+
+  return (
+    <MonacoEditor
+      value={value}
+      onChange={onChange}
+      language={language}
+      onMount={(editor) => {
+        editorRef.current = editor
+        editor.addAction({
+          id: 'format-document',
+          label: 'Format Document',
+          keybindings: [monaco.KeyMod.CtrlCmd | monaco.KeyCode.KeyS],
+          run: () => editor.getAction('editor.action.formatDocument')?.run()
+        })
+      }}
+    />
+  )
+}
+```
+
+**Why React?** Third-party libraries expect imperative APIs (refs, lifecycle methods). JSON can reference the wrapper, but can't create it.
+
+## The Hybrid Pattern
+
+### JSON References React Components
+
+JSON schemas can reference any React component via the component registry:
+
+```json
+{
+  "id": "code-editor-section",
+  "type": "div",
+  "children": [
+    {
+      "id": "monaco-editor",
+      "type": "LazyMonacoEditor",
+      "props": {
+        "language": "typescript",
+        "theme": "vs-dark"
+      }
+    }
+  ]
+}
+```
+
+The `LazyMonacoEditor` is a React component with hooks, refs, and complex logic. JSON just *configures* it.
+
+### Component Registry: The Bridge
+
+```tsx
+// src/lib/json-ui/component-registry.ts
+export const componentRegistry: ComponentRegistry = {
+  // Simple components (could be JSON, but registered for convenience)
+  'Button': Button,
+  'Card': Card,
+  'Input': Input,
+
+  // Complex components (MUST be React)
+  'LazyMonacoEditor': LazyMonacoEditor,
+  'DataSourceManager': DataSourceManager,
+  'ComponentTree': ComponentTree,
+  'SchemaEditor': SchemaEditor,
+
+  // Hook-based components
+  'ProjectDashboard': ProjectDashboard,  // uses multiple hooks
+  'CodeEditor': CodeEditor,              // uses useEffect, useRef
+  'JSONModelDesigner': JSONModelDesigner, // uses custom hooks
+}
+```
+
+### The 68 React Components
+
+These aren't legacy cruft - they're **essential implementation**:
+
+| Component Type | Count | Why React? |
+|----------------|-------|------------|
+| Hook-based managers | 15 | useState, useEffect, useCallback |
+| Event-heavy UIs | 12 | Complex event handlers, drag-and-drop |
+| Third-party wrappers | 8 | Monaco, Chart.js, D3 integrations |
+| Recursive renderers | 6 | Tree views, nested structures |
+| Complex forms | 10 | Validation, multi-step flows |
+| Dialog/Modal managers | 8 | Portal rendering, focus management |
+| Real-time features | 5 | WebSocket, polling, live updates |
+| Lazy loaders | 4 | Code splitting, dynamic imports |
+
+## When to Use What
+
+### Use JSON When:
+✅ Composing existing components
+✅ Configuring layouts and styling
+✅ Defining data sources and bindings
+✅ Simple linear action chains
+✅ Static page structure
+✅ Theming and branding
+✅ Feature flags and toggles
+
+### Use React When:
+✅ Complex state management (hooks)
+✅ Imperative APIs (refs, third-party libs)
+✅ Advanced event handling (validation, async)
+✅ Recursive algorithms
+✅ Performance optimization (memo, virtualization)
+✅ Type-safe business logic (classes, interfaces)
+✅ Side effects and lifecycle management
+
+## Real-World Example: Data Source Manager
+
+### What's in JSON
+```json
+{
+  "id": "data-source-section",
+  "type": "Card",
+  "children": [
+    {
+      "type": "CardHeader",
+      "children": [
+        { "type": "CardTitle", "children": "Data Sources" }
+      ]
+    },
+    {
+      "type": "CardContent",
+      "children": [
+        {
+          "id": "ds-manager",
+          "type": "DataSourceManager",
+          "dataBinding": {
+            "dataSources": { "source": "pageSources" }
+          },
+          "events": [{
+            "event": "onChange",
+            "actions": [
+              { "type": "setState", "target": "pageSources", "valueFrom": "event" }
+            ]
+          }]
+        }
+      ]
+    }
+  ]
+}
+```
+
+**JSON handles:** Layout, composition, data binding, simple state updates
+
+### What's in React
+```tsx
+// src/components/organisms/DataSourceManager.tsx
+export function DataSourceManager({ dataSources, onChange }: Props) {
+  // ✅ Hook for complex state management
+  const {
+    dataSources: localSources,
+    addDataSource,
+    updateDataSource,
+    deleteDataSource,
+    getDependents,  // ← Complex computed logic
+  } = useDataSourceManager(dataSources)
+
+  // ✅ Local UI state
+  const [editingSource, setEditingSource] = useState<DataSource | null>(null)
+  const [dialogOpen, setDialogOpen] = useState(false)
+
+  // ✅ Complex event handler with validation
+  const handleDeleteSource = (id: string) => {
+    const dependents = getDependents(id)
+    if (dependents.length > 0) {
+      toast.error(`Cannot delete: ${dependents.length} sources depend on it`)
+      return
+    }
+    deleteDataSource(id)
+    onChange(localSources.filter(ds => ds.id !== id))
+    toast.success('Data source deleted')
+  }
+
+  // ✅ Conditional rendering based on complex state
+  const groupedSources = useMemo(() => ({
+    kv: localSources.filter(ds => ds.type === 'kv'),
+    computed: localSources.filter(ds => ds.type === 'computed'),
+    static: localSources.filter(ds => ds.type === 'static'),
+  }), [localSources])
+
+  return (
+    <div>
+      {localSources.length === 0 ? (
+        <EmptyState />
+      ) : (
+        <Stack>
+          <DataSourceGroup sources={groupedSources.kv} />
+          <DataSourceGroup sources={groupedSources.static} />
+          <DataSourceGroup sources={groupedSources.computed} />
+        </Stack>
+      )}
+      <DataSourceEditorDialog
+        open={dialogOpen}
+        dataSource={editingSource}
+        onSave={handleSaveSource}
+      />
+    </div>
+  )
+}
+```
+
+**React handles:** Hooks, validation, dependency checking, grouping logic, dialog state
+
+## The Power of Hybrid
+
+### Flexibility
+- **JSON**: Quick changes, visual editing, non-developer friendly
+- **React**: Full programming power when needed
+
+### Composition
+- **JSON**: Compose pages from molecules and organisms
+- **React**: Implement the organisms with complex logic
+
+### Evolution
+- **Start Simple**: Build in JSON, reference simple React components
+- **Add Complexity**: When logic grows, extract to custom React component
+- **Stay Declarative**: JSON schema stays clean, complexity hidden in components
+
+### Example Evolution
+
+**Day 1 - Pure JSON:**
+```json
+{
+  "type": "Button",
+  "events": [{ "event": "onClick", "actions": [{ "type": "toast" }] }]
+}
+```
+
+**Day 30 - Need validation:**
+```json
+{
+  "type": "ValidatedButton",  // ← Custom React component
+  "props": { "validationRules": ["required", "email"] }
+}
+```
+
+```tsx
+// Custom component when JSON isn't enough
+function ValidatedButton({ validationRules, onClick, ...props }) {
+  const validate = useValidation(validationRules)
+
+  const handleClick = () => {
+    if (!validate()) {
+      toast.error('Validation failed')
+      return
+    }
+    onClick?.()
+  }
+
+  return <Button onClick={handleClick} {...props} />
+}
+```
+
+**Day 90 - Complex workflow:**
+```json
+{
+  "type": "WorkflowButton",  // ← Even more complex component
+  "props": { "workflowId": "user-onboarding" }
+}
+```
+
+The JSON stays simple. The complexity lives in well-tested React components.
+
+## Conclusion
+
+The **68 React components aren't cruft** - they're the **essential implementation layer** that makes the JSON system powerful:
+
+- **Hooks** manage complex state
+- **Events** handle imperative interactions
+- **Interfaces** provide type safety
+- **Classes** encapsulate business logic
+- **Third-party integrations** extend capabilities
+
+JSON provides the **declarative structure**. React provides the **imperative power**.
+
+Together, they create a system that's:
+- **Easy** for simple cases (JSON)
+- **Powerful** for complex cases (React)
+- **Scalable** (add React components as needed)
+- **Maintainable** (JSON is readable, React is testable)
+
+This is the architecture of modern low-code platforms - not "no code," but **"right tool for the right job."**

docs/JSON-UI-SYSTEM.md

 The JSON UI System is a declarative framework for building React user interfaces from JSON configurations. Instead of writing React components, you define your UI structure, data sources, and event handlers in JSON files, which are then rendered dynamically.
 
+This document now serves as the consolidated reference for the JSON UI system. Legacy notes like `JSON_COMPONENTS.md`, `JSON_EXPRESSION_SYSTEM.md`, `JSON_COMPATIBILITY_IMPLEMENTATION.md`, the component usage report, and the old `json-components-list.json` artifact have been retired in favor of keeping the guidance in one place.

+# JSON-First Architecture
+
+## Overview
+
+This low-code platform uses a **JSON-first architecture** where the entire application is defined declaratively in JSON, eliminating React boilerplate and enabling visual editing, version control, and runtime customization.
+
+## Core Principles
+
+### 1. Everything is JSON
+- **Pages**: All 35 application pages defined in JSON schemas
+- **Components**: Atomic design library (atoms, molecules, organisms) in JSON
+- **Themes**: Complete theming system configurable via JSON
+- **Data**: State, bindings, and data sources declared in JSON
+- **Actions**: Event handlers and side effects defined in JSON
+
+### 2. Composition via $ref
+JSON files reference each other using JSON Schema `$ref`:
+```json
+{
+  "id": "dashboard",
+  "components": [
+    { "$ref": "./molecules/dashboard-header.json" },
+    { "$ref": "./molecules/stats-grid.json" }
+  ]
+}
+```
+
+### 3. One Definition Per File
+Following single-responsibility principle:
+- 1 function per TypeScript file
+- 1 type per TypeScript file
+- 1 component definition per JSON file
+- Compose larger structures via $ref
+

+## JSON Schema Features
+
+### Page Schema
+```json
+{
+  "$schema": "./schema/page-schema.json",
+  "id": "dashboard-simple",
+  "name": "Project Dashboard",
+  "description": "Overview of your project",
+  "icon": "ChartBar",
+  "layout": {
+    "$ref": "./layouts/single-column.json"
+  },
+  "dataSources": [
+    {
+      "id": "projectStats",
+      "$ref": "./data-sources/kv-storage.json",
+      "key": "project-stats",
+      "defaultValue": { "files": 0, "models": 0 }
+    }
+  ],
+  "components": [
+    { "$ref": "./molecules/dashboard-header.json" },
+    { "$ref": "./molecules/stats-grid.json" }
+  ]
+}
+```
+
+### Data Binding
+```json
+{
+  "id": "files-value",
+  "type": "div",
+  "props": {
+    "className": "text-2xl font-bold",
+    "children": "0"
+  },
+  "dataBinding": {
+    "source": "projectStats",
+    "path": "files"
+  }
+}
+```
+
+### Actions
+```json
+{
+  "type": "Button",
+  "events": [
+    {
+      "event": "onClick",
+      "actions": [
+        {

+    "value": 0
+  },
+  "children": [
+    { "type": "p", "children": "No custom colors" }
+  ]
+}
+```
+
+## Theming System
+
+### JSON Theme Definition
+The entire theming system is JSON-based (theme.json):
+
+```json
+{
+  "sidebar": {
+    "width": "16rem",
+    "backgroundColor": "oklch(0.19 0.02 265)",
+    "foregroundColor": "oklch(0.95 0.01 265)"
+  },
+  "colors": {
+    "primary": "oklch(0.58 0.24 265)",
+    "accent": "oklch(0.75 0.20 145)",
+    "background": "oklch(0.15 0.02 265)"
+  },
+  "typography": {
+    "fontFamily": {
+      "body": "'IBM Plex Sans', sans-serif",
+      "heading": "'JetBrains Mono', monospace"
+    }
+  },
+  "spacing": {
+    "radius": "0.5rem"
+  }
+}
+```
+
+### Runtime Theme Editing
+Users can create theme variants and customize colors/fonts via JSON:
+
+```json
+{
+  "activeVariantId": "dark",
+  "variants": [
+    {
+      "id": "dark",
+      "name": "Dark Mode",
+      "colors": {
+        "primary": "#7c3aed",
+        "secondary": "#38bdf8",
+        "customColors": {
+          "success": "#10b981",
+          "warning": "#f59e0b"
+        }
+      }
+    }
+  ]
+}
+```
+
+## Data Sources
+
+### KV Storage
+```json
+{
+  "id": "userData",
+  "type": "kv",
+  "key": "user-settings",
+  "defaultValue": { "theme": "dark" }
+}
+```
+
+### Computed Sources
+```json
+{
+  "id": "totalFiles",
+  "type": "computed",
+  "compute": "(data) => data.files.length",
+  "dependencies": ["files"]
+}
+```
+
+### Static Sources
+```json
+{
+  "id": "tabs",
+  "type": "static",
+  "defaultValue": ["colors", "typography", "preview"]
+}
+```
+
+## Benefits Over Traditional React
+
+### Traditional React Component (~50 lines)
+```tsx
+import { useState } from 'react'
+import { Card } from '@/components/ui/card'
+
+interface DashboardProps {
+  initialData?: { files: number }
+}
+
+export function Dashboard({ initialData }: DashboardProps) {
+  const [stats, setStats] = useState(initialData || { files: 0 })
+
+  return (
+    <div className="p-6">
+      <div className="border-b pb-4">
+        <h1 className="text-2xl font-bold">Dashboard</h1>
+      </div>
+      <Card className="p-6">
+        <div className="text-2xl font-bold">{stats.files}</div>
+        <div className="text-sm text-muted">Files</div>
+      </Card>
+    </div>
+  )
+}
+```
+
+### JSON Equivalent (~15 lines)
+```json
+{
+  "id": "dashboard",
+  "dataSources": [
+    { "id": "stats", "type": "kv", "key": "stats" }
+  ],
+  "components": [
+    { "$ref": "./molecules/dashboard-header.json" },
+    {
+      "$ref": "./molecules/stat-card.json",
+      "dataBinding": { "source": "stats", "path": "files" }
+    }
+  ]
+}
+```
+
+## Eliminated Boilerplate
+
+✅ **No imports** - Components referenced by type string
+✅ **No TypeScript interfaces** - Types inferred from registry
+✅ **No useState/useEffect** - State declared in dataSources
+✅ **No event handlers** - Actions declared in events array
+✅ **No prop drilling** - Data binding handles it
+✅ **No component exports** - Automatic via registry
+✅ **No JSX nesting** - Flat JSON structure with $ref
+
+## Coverage Statistics
+
+- **35/35 pages** use JSON schemas (100%)
+- **0/35 pages** use React component references
+- **109 JSON component files** created
+  - 23 atoms
+  - 23 molecules
+  - 8 organisms
+  - 55 page schemas
+- **68 React components** remain as implementation layer
+
+## Potential Cleanup Targets
+
+### Deprecated Files (Safe to Remove)
+- `src/config/default-pages.json` - Replaced by pages.json
+- `src/config/json-demo.json` - Old demo file
+- `src/config/template-ui.json` - Replaced by JSON schemas
+
+### Keep (Still Used)
+- `src/config/pages.json` - Active router configuration
+- `theme.json` - Active theming system
+- `src/config/feature-toggle-settings.json` - Feature flags
+- All JSON schemas in `src/config/pages/`
+
+## Best Practices
+
+### 1. Atomic Granularity
+Break components into smallest reusable units:
+```
+❌ dashboard.json (monolithic)
+✅ dashboard-header.json + stats-grid.json + stat-card.json
+```
+
+### 2. $ref Composition
+Always compose via references, never inline:
+```json
+❌ { "type": "div", "children": [ ... 50 lines ... ] }
+✅ { "$ref": "./molecules/complex-section.json" }
+```
+
+### 3. Single Responsibility
+One purpose per JSON file:
+```
+✅ stat-card-base.json (template)
+✅ stat-card-files.json (specific instance)
+✅ stat-card-models.json (specific instance)
+```
+
+### 4. Descriptive IDs
+Use semantic IDs that describe purpose:
+```json
+{ "id": "dashboard-header" }      // ✅ Good
+{ "id": "div-1" }                 // ❌ Bad
+```
+
+## Future Enhancements
+
+- [ ] Visual JSON editor for drag-and-drop page building
+- [ ] Theme marketplace with sharable JSON themes
+- [ ] Component library with searchable JSON snippets
+- [ ] JSON validation and IntelliSense in VSCode
+- [ ] Hot-reload JSON changes without app restart
+- [ ] A/B testing via JSON variant switching
+- [ ] Multi-tenant customization via tenant-specific JSONs
+
+## Conclusion
+
+This JSON-first architecture transforms React development from code-heavy to configuration-driven, enabling:
+- **Visual editing** without touching code
+- **Version control** friendly (JSON diffs)
+- **Runtime customization** (load different JSONs)
+- **Non-developer accessibility** (JSON is readable)
+- **Rapid prototyping** (compose existing pieces)
+- **Consistent patterns** (enforced by schema)
+
+All without sacrificing the power of React when you need it - complex interactive components can still be written in React and referenced from JSON.

+# JSON Component Conversion Tasks
+
+This task list captures the next steps for expanding JSON UI coverage, split between **component migrations** and **framework enablers**.
+
+## Implementation Notes
+
+- Component trees can live as JSON definitions.
+- Custom behavior should be organized into hooks where appropriate.

+### Action & Conditional Syntax
+- Use supported JSON UI action types (for example, `set-value`, `toggle-value`, `show-toast`) with `target`, `path`, `value`, or `expression` fields instead of legacy `setState` actions.

+## Component Pattern Templates
+
+Use these patterns as starting points when authoring JSON schemas. Each example includes
+recommended prop shapes and binding strategies for predictable rendering and data flow.
+
+### Form Pattern (Create/Edit)
+
+**Recommended prop shape**
+- `name`: field identifier used in data mappings.
+- `label`: user-facing label.
+- `placeholder`: optional hint text.
+- `type`: input type (`text`, `email`, `number`, `date`, etc.).
+- `required`: boolean for validation UI.
+
+**Schema example**
+```typescript
+{
+  id: 'profile-form',
+  type: 'form',
+  props: {
+    className: 'space-y-4'
+  },
+  children: [
+    {
+      id: 'first-name',
+      type: 'Input',
+      props: {
+        name: 'firstName',
+        label: 'First name',
+        placeholder: 'Ada',
+        required: true
+      },
+      bindings: {
+        value: { source: 'formState', path: 'firstName' }
+      },
+      events: [
+        {
+          event: 'change',
+          actions: [
+            {
+              type: 'set-value',
+              target: 'formState',
+              path: 'firstName',
+              compute: (data, event) => event.target.value
+            }
+          ]
+        }
+      ]
+    },
+    {
+      id: 'email',
+      type: 'Input',
+      props: {
+        name: 'email',
+        label: 'Email',
+        placeholder: 'ada@lovelace.dev',
+        type: 'email'
+      },
+      bindings: {
+        value: { source: 'formState', path: 'email' }
+      },
+      events: [
+        {
+          event: 'change',
+          actions: [
+            {
+              type: 'set-value',
+              target: 'formState',
+              path: 'email',
+              compute: (data, event) => event.target.value
+            }
+          ]
+        }
+      ]
+    },
+    {
+      id: 'save-profile',
+      type: 'Button',
+      props: { children: 'Save profile' },
+      events: [
+        {
+          event: 'click',
+          actions: [
+            {
+              type: 'create',
+              target: 'profiles',
+              compute: (data) => ({
+                id: Date.now(),
+                ...data.formState
+              })
+            },
+            {
+              type: 'set-value',
+              target: 'formState',
+              value: { firstName: '', email: '' }
+            }
+          ]
+        }
+      ]
+    }
+  ]
+}
+```
+
+**Recommended bindings**
+- Use `bindings.value` for inputs and update a single `formState` data source.
+- Use `set-value` with `path` to update individual fields and avoid cloning the whole object.
+
+### Card Pattern (Summary/Stat)
+
+**Recommended prop shape**
+- `title`: primary label.
+- `description`: supporting copy.
+- `badge`: optional status tag.
+- `icon`: optional leading icon name or component id.
+
+**Schema example**
+```typescript
+{
+  id: 'stats-card',
+  type: 'Card',
+  props: { className: 'p-4' },
+  children: [
+    {
+      id: 'card-header',
+      type: 'div',
+      props: { className: 'flex items-center justify-between' },
+      children: [
+        {
+          id: 'card-title',
+          type: 'h3',
+          bindings: {
+            children: { source: 'stats', path: 'title' }
+          },
+          props: { className: 'text-lg font-semibold' }
+        },
+        {
+          id: 'card-badge',
+          type: 'Badge',
+          bindings: {
+            children: { source: 'stats', path: 'status' },
+            variant: {
+              source: 'stats',
+              path: 'status',
+              transform: (value) => (value === 'Active' ? 'success' : 'secondary')
+            }
+          }
+        }
+      ]
+    },
+    {
+      id: 'card-description',
+      type: 'p',
+      props: { className: 'text-sm text-muted-foreground' },
+      bindings: {
+        children: { source: 'stats', path: 'description' }
+      }
+    }
+  ]
+}
+```
+
+**Recommended bindings**
+- Bind the card text fields directly to a `stats` data source.
+- Use `transform` for simple presentation mappings (status to badge variant).
+
+### List Pattern (Collection + Row Actions)
+
+**Recommended prop shape**
+- `items`: array data source bound at the list container.
+- `keyField`: unique field for list keys.
+- `primary`: main text content (usually `name` or `title`).
+- `secondary`: supporting text (optional).
+- `actions`: array of action configs for row-level events.
+
+**Schema example**
+```typescript
+{
+  id: 'task-list',
+  type: 'div',
+  bindings: {
+    children: {
+      source: 'tasks',
+      transform: (items) =>
+        items.map((item) => ({
+          id: `task-${item.id}`,
+          type: 'div',
+          props: { className: 'flex items-center justify-between py-2' },
+          children: [
+            {
+              id: `task-name-${item.id}`,
+              type: 'span',
+              bindings: {
+                children: { source: 'item', path: 'name' }
+              }
+            },
+            {
+              id: `task-toggle-${item.id}`,
+              type: 'Button',
+              props: { size: 'sm', variant: 'outline' },
+              bindings: {
+                children: {
+                  source: 'item',
+                  path: 'completed',
+                  transform: (value) => (value ? 'Undo' : 'Complete')
+                }
+              },
+              events: [
+                {
+                  event: 'click',
+                  actions: [
+                    {
+                      type: 'update',
+                      target: 'tasks',
+                      id: item.id,
+                      compute: (data) => ({
+                        ...item,
+                        completed: !item.completed
+                      })
+                    }
+                  ]
+                }
+              ]
+            }
+          ]
+        }))
+    }
+  }
+}
+```
+
+**Recommended bindings**
+- Use a `transform` to map collection items into child component schemas.
+- Use `{ source: 'item', path: 'field' }` when binding inside the item loop for clarity and efficiency.
