---

## Phase 6: Server Configuration Architecture

### What It Does
Manages environment-based configuration with public/private separation. Prevents secrets from being exposed to the browser.

### Key Components

**1. Server-Side (`tools/api/config.py`)**
```python
# Public config (safe for browser)
DSS_HOST = os.environ.get("DSS_HOST", "localhost")
DSS_PORT = os.environ.get("DSS_PORT", "3456")
STORYBOOK_PORT = 6006

# Private config (server-only)
FIGMA_API_KEY = os.environ.get("FIGMA_API_KEY")
DATABASE_URL = os.environ.get("DATABASE_URL")

# Endpoint: /api/config
def get_public_config():
    return {
        "dssHost": DSS_HOST,
        "dssPort": DSS_PORT,
        "storybookPort": STORYBOOK_PORT
    }
```

**2. Client-Side (`admin-ui/js/core/config-loader.js`)**
- Blocking async pattern: `await loadConfig()` before app initializes
- Prevents race conditions
- Methods: `getConfig()`, `getDssHost()`, `getDssPort()`, `getStorybookUrl()`

### Deployed Endpoints
```
✅ GET /api/config                 → Returns public config
✅ GET /api/figma/health          → Figma service status
✅ GET /health                    → Server health check
```

### Live Configuration
```json
{
  "dssHost": "dss.overbits.luz.uy",
  "dssPort": "3456",
  "storybookPort": 6006
}
```

## Phase 7: Component Registry Pattern

### What It Does
Extensible registry system for integrating external tools (Storybook, Figma, etc.) without code changes. Components define their own config schema and health checks.

### Key Components

**1. Registry Structure (`admin-ui/js/core/component-config.js`)**

Each component defines:
- `id` - Unique identifier
- `name` - Display name
- `description` - Human-readable description
- `icon` - Icon name
- `category` - One of: documentation, design, project
- `config` - JSON schema for settings
- `getUrl()` - Generate URL dynamically
- `checkStatus()` - Health check async function

### Implemented Components

#### Storybook (✅ Enabled)
```javascript
{
  id: 'storybook',
  name: 'Storybook',
  description: 'Component documentation and playground',
  icon: 'book',
  category: 'documentation',
  config: {
    port: { type: 'number', default: 6006, readonly: true },
    theme: { type: 'select', options: ['light', 'dark', 'auto'], default: 'auto' },
    showDocs: { type: 'boolean', default: true }
  },
  getUrl() { return `https://dss.overbits.luz.uy/storybook/` },
  async checkStatus() { /* health check */ }
}
```

#### Figma (✅ Enabled)
```javascript
{
  id: 'figma',
  name: 'Figma',
  description: 'Design file integration and token extraction',
  icon: 'figma',
  category: 'design',
  config: {
    apiKey: { type: 'password', label: 'API Token', sensitive: true },
    fileKey: { type: 'text', label: 'Default File Key' },
    autoSync: { type: 'boolean', default: false }
  },
  getUrl() { return 'https://www.figma.com' },
  async checkStatus() { /* check via /api/figma/health */ }
}
```

#### Jira (⏳ Placeholder)
```javascript
{
  id: 'jira',
  enabled: false,  // Not yet implemented
  // ... config structure defined for future use
}
```

#### Confluence (⏳ Placeholder)
```javascript
{
  id: 'confluence',
  enabled: false,  // Not yet implemented
  // ... config structure defined for future use
}
```

### Helper Functions
```javascript
getEnabledComponents()           // Returns active components only
getComponentsByCategory(cat)     // Filter by category
getComponent(id)                 // Get single component
getComponentSetting(id, key)     // Get persisted setting
setComponentSetting(id, key, val) // Persist setting to localStorage
getComponentSettings(id)         // Get all settings for component
```

### Storage
Settings stored in localStorage with key pattern:
```
dss_component_{componentId}_{settingKey}
```

### API Endpoints
```
✅ /api/config/figma             → Figma config & features
✅ /api/figma/extract-variables  → Extract design tokens
✅ /api/figma/extract-components → Extract components
✅ /api/figma/extract-styles     → Extract styles
✅ /api/figma/sync-tokens        → Sync to database
```

## Phase 8: Enterprise Patterns

### What It Does
Four production-grade patterns for resilience, observability, and crash recovery.

### 1. Workflow Persistence 📦

**Purpose**: Save/restore application state for crash recovery and session restoration.

**Key Features**:
- Create snapshots of current state
- Auto-save every 30 seconds
- Keep 10 most recent snapshots
- Restore from any snapshot
- Export/import snapshots as JSON

**Methods**:
```javascript
persistence.snapshot()           // Create snapshot object
persistence.saveSnapshot()       // Save to localStorage
persistence.getSnapshots()       // Get all saved snapshots
persistence.restoreSnapshot(id)  // Restore from ID
persistence.startAutoSave()      // Enable periodic auto-save
persistence.exportSnapshots()    // Export as JSON
persistence.importSnapshots()    // Import from JSON
```

**Storage**: localStorage key `dss-workflow-state` (max 10 snapshots)

---

### 2. Audit Logger 📋

**Purpose**: Track all user actions, state changes, and API calls for compliance and debugging.

**Key Features**:
- Log user actions (button clicks, form submissions)
- Track state changes (what changed, old → new value)
- Log API calls (method, endpoint, status, response time)
- Log errors with full stack traces
- Log permission checks (audit trail)
- Automatic sensitive data redaction
- Filter logs by action, category, level, time range
- Export logs as JSON

**Methods**:
```javascript
auditLogger.logAction(action, details)               // User action
auditLogger.logStateChange(key, oldVal, newVal)     // State change
auditLogger.logApiCall(method, endpoint, status)    // API call
auditLogger.logError(error, context)                // Error
auditLogger.logPermissionCheck(action, allowed)     // Permission
auditLogger.getLogs(filters)                        // Query logs
auditLogger.getStats()                              // Statistics
auditLogger.exportLogs()                            // Export JSON
```

**Storage**: localStorage key `dss-audit-logs` (max 1000 entries)

**Automatic Redaction**: Passwords, tokens, API keys, secrets

---

### 3. Route Guards 🔐

**Purpose**: Enforce permissions and authentication before allowing access to routes.

**Pre-Built Guards**:
- **settings** → TEAM_LEAD | SUPER_ADMIN
- **admin** → SUPER_ADMIN only
- **projects** → Active team required
- **figma** → DEVELOPER or higher

**Methods**:
```javascript
routeGuard.canActivate(route)              // Check route access
routeGuard.hasPermission(permission)       // Check permission
routeGuard.validateAction(action, resource) // Validate action
routeGuard.register(route, guardFn)        // Custom guard
```

**Permission Levels**:
```
SUPER_ADMIN: all permissions ['*']
TEAM_LEAD:   ['read', 'write', 'sync', 'manage_team']
DEVELOPER:   ['read', 'write', 'sync']
VIEWER:      ['read']
```

---

### 4. Error Recovery 🚑

**Purpose**: Handle crashes, recover lost state, and provide resilience.

**Key Features**:
- Global error handlers (unhandled promises, window errors)
- Create recovery points before risky operations
- Auto-detect crash conditions
- Categorize errors (network, timeout, auth, permission, notfound)
- Recovery strategies for each category
- Retry with exponential backoff
- Crash reports with full analysis

**Methods**:
```javascript
errorRecovery.createRecoveryPoint(label)   // Create checkpoint
errorRecovery.recover(pointId)             // Restore from checkpoint
errorRecovery.detectCrash()                // Check if crashed
errorRecovery.retry(operation, maxRetries) // Retry with backoff
errorRecovery.getCrashReport()             // Full analysis
errorRecovery.exportCrashReport()          // Export JSON
```

**Error Categories**:
- **network** - Network errors (retryable)
- **timeout** - Request timeouts (retryable)
- **auth** - Authentication failures
- **permission** - Permission denied
- **notfound** - Resource not found
- **unknown** - Other errors

**Recovery Points**: Stores up to 5 checkpoints with state & logs
