# BW Babel — Phase 1 Foundation Build Progress

**Project:** BW Babel v3.0.0-babel (Schema Markup Made Simple)  
**Phase:** 1 — Foundation Refactoring  
**Started:** 2026-08-05  
**Location:** `/srv/apps/bw-plugins/wp-content/plugins/bw-babel/`

---

## Overview

BW Babel is a fresh plugin built from the ground up with modern architecture. Phase 1 establishes:
- **Services Layer** — pure business logic, reusable across the plugin
- **Form Builder** — declarative form definitions instead of massive view files
- **Page Classes** — modular admin pages that delegate to services

This is a complete rebuild, not a refactor of `bw-ai-schema-pro`. All features from v2.6.0 will be ported to Babel in Phase 1-4.

## Architecture

### Services Layer Pattern

Each service handles business logic for one feature area:

```php
class BW_Babel_Service_Organization {
    public static function get() { }           // Read
    public static function save( $data ) { }   // Write
    public static function validate( $data ) { } // Validation
    public static function get_field_definitions() { } // Form definitions
}
```

**Principles:**
- ✅ Static methods (stateless)
- ✅ No WordPress hooks (pure functions)
- ✅ Single responsibility
- ✅ Testable (no side effects)
- ✅ Reusable (pages, AJAX, CLI)

### Form Builder Pattern (Next)

Forms defined declaratively:

```php
$form = BW_Babel_Form_Builder::build_form( 'organization', [
    [
        'name' => 'org_name',
        'label' => 'Organization Name',
        'type' => 'text',
        'required' => true,
    ],
    // ... more fields
] );

echo $form->render();
if ( $_POST ) {
    $result = $form->validate_and_save( $_POST );
}
```

### Page Classes Pattern (Next)

Each admin page is a simple class:

```php
class BW_Babel_Page_Organization {
    public function render() {
        $data = BW_Babel_Service_Organization::get();
        // ... render page
    }
    
    public function handle_save() {
        return BW_Babel_Service_Organization::save( $_POST );
    }
}
```

## Current Session Work

### Starting Point

- Fresh plugin directory: `/srv/apps/bw-plugins/wp-content/plugins/bw-babel/`
- No existing code to migrate
- Clean slate for architecture

### Work Log

**2026-08-05 — Session 1: Task 1.1 COMPLETED ✅**

✅ **Created New Plugin Structure:**

1. **Main Plugin File** (`bw-babel.php`)
   - Plugin headers (name, description, version, author, etc.)
   - Autoloader for BW_Babel_* classes
   - Hooks and dependencies loading
   - Activation/deactivation stubs

2. **Core Class** (`includes/class-bw-babel-core.php`)
   - Singleton bootstrap
   - Hook registration
   - Admin page registration
   - Activation/deactivation handlers

3. **5 Service Classes** (`admin/services/`)
   - Organization service (312 lines)
   - Locations service (352 lines)
   - People service (325 lines)
   - Survey service (364 lines)
   - Cache service (197 lines)
   - **Total: 1,550 lines of pure business logic**

**Key Features in Services:**

| Service | What It Does |
|---------|------|
| **Organization** | Get/save org data, 20 field definitions, business types |
| **Locations** | CRUD locations, service areas, room management |
| **People** | Team config, author box, team member queries |
| **Survey** | Survey config, response CRUD, moderation workflow |
| **Cache** | Cache status, health checks, invalidation |

**Database Pattern:**
- Options: `bw_babel_*` prefix (ready for migration from `bw_schema_*`)
- Custom tables: `wp_bw_babel_survey_responses`
- Post meta: `_bw_babel_*`

---

## Next Steps

### Task 1.2: Form Builder (2-3 days)

Create declarative form system:

1. **BW_Babel_Form_Builder** — main class
   - `build_form()` — create form from field definitions
   - `render()` — output HTML
   - `validate_and_save()` — process submission

2. **BW_Babel_Form_Fields** — field types
   - Text, email, url, tel, textarea
   - Dropdown, checkboxes, radio
   - Date, time, datetime
   - Media picker

3. **BW_Babel_Form_Validator** — validation rules
   - Required, email, url, phone
   - Min/max length, patterns
   - Custom validators

### Then: Task 1.3 - Page Classes (3-4 days)

Convert admin UI to modular pages:
- Dashboard (status overview)
- Organization (identity settings)
- Locations (multi-location management)
- People (authors & team)
- Content (post types, FAQ, breadcrumbs)
- Tools (export, import, cache, conflicts)
- Help (docs & schema reference)

---
