+#### Component Documentation (Storybook)
+
+**🚨 CRITICAL GUARDRAIL: Stories Are Data, Not Code**
+
+Like tests, Storybook stories must be JSON, not TypeScript!
+
+**❌ WRONG: Writing new .stories.tsx files**
+```typescript
+// DON'T DO THIS - No new .stories.tsx files!
+export const HomePage: Story = {
+  render: () => <HomePage title="Welcome" />
+}
+```

+  }]
+}
+```
+
+**Story Location Rules:**
+- ✅ `packages/{package_name}/storybook/stories.json` - Package stories (PREFERRED)
+- ✅ `storybook/src/stories/*.stories.tsx` - Existing stories (legacy, don't add more)
+- ❌ NEVER create new `.stories.tsx` files - use JSON instead!
+
+**JSON Story Loader:**
+- Stories defined in `packages/*/storybook/stories.json` are auto-discovered
+- `storybook/json-loader/` loads and renders JSON stories directly
+- No code generation - JSON is rendered at runtime
+- Uses `DynamicStory` component to render from JSON definitions

+# Test & Story Conversion Guide
+
+## Overview
+
+Old Playwright tests (`.spec.ts`) and Storybook stories (`.stories.tsx`) can be converted to JSON format for direct interpretation at runtime.
+
+## ✅ Benefits of JSON Format
+
+1. **True Meta Architecture**: Tests/stories are data, not code
+2. **No Code Generation**: JSON is directly executed/rendered
+3. **Immediate Changes**: Edit JSON → Effect is immediate
+4. **Single Source of Truth**: JSON only (no generated code)
+5. **Package Ownership**: Each package owns its test/story data
+6. **Schema Validated**: Definitions conform to JSON schemas
+
+## 🚨 Critical Rules
+
+### Tests
+- ✅ NEW TESTS: Write in `packages/{name}/playwright/tests.json`
+- ✅ EXISTING: Keep old `.spec.ts` files (don't break existing tests)
+- ❌ NEVER: Create new `.spec.ts` files
+
+### Stories
+- ✅ NEW STORIES: Write in `packages/{name}/storybook/stories.json`
+- ✅ EXISTING: Keep old `.stories.tsx` files (don't break existing stories)
+- ❌ NEVER: Create new `.stories.tsx` files
+
+## Conversion Examples
+
+### Playwright Test Conversion
+
+**Before (TypeScript):**
+```typescript
+// e2e/login.spec.ts
+import { test, expect } from '@playwright/test'
+
+test('should login successfully', async ({ page }) => {
+  await page.goto('/login')
+  await page.fill('[name="username"]', 'testuser')
+  await page.fill('[name="password"]', 'testpass')
+  await page.click('button:has-text("Login")')
+  await expect(page).toHaveURL('/dashboard')
+})
+```
+
+**After (JSON):**
+```json
+// packages/auth/playwright/tests.json
+{
+  "$schema": "https://metabuilder.dev/schemas/package-playwright.schema.json",
+  "package": "auth",
+  "version": "1.0.0",
+  "tests": [{
+    "name": "should login successfully",
+    "tags": ["@auth", "@smoke"],
+    "steps": [
+      {
+        "description": "Navigate to login page",
+        "action": "navigate",
+        "url": "/login"
+      },
+      {
+        "description": "Fill username",
+        "action": "fill",
+        "selector": "[name='username']",
+        "value": "testuser"
+      },
+      {
+        "description": "Fill password",
+        "action": "fill",
+        "selector": "[name='password']",
+        "value": "testpass"
+      },
+      {
+        "description": "Click login button",
+        "action": "click",
+        "role": "button",
+        "text": "Login"
+      },
+      {
+        "description": "Verify redirected to dashboard",
+        "action": "expect",
+        "selector": "body",
+        "assertion": {
+          "matcher": "toHaveURL",
+          "expected": "/dashboard"
+        }
+      }
+    ]
+  }]
+}
+```
+
+### Storybook Story Conversion
+
+**Before (TypeScript):**
+```typescript
+// storybook/src/stories/HomePage.stories.tsx
+import type { Meta, StoryObj } from '@storybook/react'
+import { HomePage } from '@/components/HomePage'
+
+const meta: Meta<typeof HomePage> = {
+  title: 'Pages/HomePage',
+  component: HomePage,
+}
+
+export default meta
+type Story = StoryObj<typeof meta>
+
+export const Default: Story = {
+  args: {
+    title: 'Welcome to MetaBuilder',
+    subtitle: 'Build apps visually'
+  }
+}
+```
+
+**After (JSON):**
+```json
+// packages/ui_home/storybook/stories.json
+{
+  "$schema": "https://metabuilder.dev/schemas/package-storybook.schema.json",
+  "title": "Pages/HomePage",
+  "description": "Home page components",
+  "stories": [{
+    "name": "Default",
+    "render": "home_page",
+    "description": "Default home page view",
+    "args": {
+      "title": "Welcome to MetaBuilder",
+      "subtitle": "Build apps visually"
+    }
+  }]
+}
+```
+
+## Existing Test Files Status
+
+### Can Be Converted (2,500+ lines)
+- `e2e/smoke.spec.ts` → `packages/smoke_tests/playwright/tests.json` ✅ DONE
+- `e2e/login.spec.ts` → `packages/auth/playwright/tests.json` ✅ DONE
+- `e2e/crud.spec.ts` → Can be converted
+- `e2e/navigation.spec.ts` → Can be converted
+- `e2e/pagination.spec.ts` → Can be converted
+- `e2e/package-loading.spec.ts` → Can be converted
+- `e2e/package-rendering.spec.ts` → Can be converted
+- `e2e/auth/*.spec.ts` → Can be converted
+- `e2e/crud/*.spec.ts` → Can be converted
+- `e2e/api/*.spec.ts` → Can be converted
+
+### Should Keep As-Is
+- `e2e/dbal-daemon/*.spec.ts` - Complex daemon testing
+- Tests with custom TypeScript logic that can't be represented in JSON
+
+### Storybook Files
+- `storybook/src/stories/*.stories.tsx` (8 files) - Can be converted
+
+## Conversion Priority
+
+1. **High Priority** - Smoke/critical tests
+   - ✅ `smoke.spec.ts` (converted)
+   - ✅ `login.spec.ts` (converted)
+
+2. **Medium Priority** - Common workflows
+   - `crud.spec.ts`
+   - `navigation.spec.ts`
+   - `auth/*.spec.ts`
+
+3. **Low Priority** - Complex/specialized tests
+   - `dbal-daemon/*.spec.ts` (keep as TypeScript)
+   - Tests with complex assertions
+
+## Running JSON Tests
+
+```bash
+# Run all JSON-defined package tests
+npm run test:e2e:json
+
+# Or explicitly
+npm run test:e2e -- e2e/json-packages.spec.ts
+
+# Run with UI mode
+npm run test:e2e:ui -- e2e/json-packages.spec.ts
+
+# Run legacy tests (still works)
+npm run test:e2e
+```
+
+## No Leftover Junk
+
+✅ **Clean Status:**
+- No generated files or directories
+- No `.bak`, `.old`, `.tmp` files
+- No leftover code generators (removed in bccc336)
+- JSON runners/loaders are clean, documented code
+
+## Documentation
+
+- `e2e/json-runner/README.md` - JSON test runner documentation
+- `storybook/json-loader/README.md` - JSON story loader documentation
+- `schemas/package-schemas/playwright.schema.json` - Test schema
+- `schemas/package-schemas/storybook_schema.json` - Story schema
+- `schemas/package-schemas/PLAYWRIGHT_SCHEMA_README.md` - Schema guide
+
+## Summary
+
+- ✅ 2 test suites converted (smoke, auth)
+- ✅ 12+ tests now in JSON format
+- ✅ JSON runner infrastructure complete
+- ✅ No code generation - direct interpretation
+- ✅ Guardrails added to AGENTS.md and CLAUDE.md
+- ✅ Clean codebase - no junk files
+- 🎯 Ready for more conversions as needed
