## GAP 5.1: WebGL VISUAL REGRESSION TESTING

### Deliverable 1: Un-skipped Unit Tests

**File:** `frontend/apps/web/src/__tests__/components/graph/SigmaGraphView.test.tsx`

**Changes:**
```
Line 11: it.skip(...) → it(...)  // "should render sigma container..."
Line 17: it.skip(...) → it(...)  // "should export SigmaGraphView component..."
```

**Status:** ✅ COMPLETE
- Both tests now active (ready to execute with canvas mocks from global setup.ts)
- Canvas 2D context mocks provided by existing test environment
- Tests validate container rendering and component export functionality

**File:** `frontend/apps/web/src/__tests__/components/graph/SigmaGraphView.enhanced.test.tsx`

**Changes:**
```
Line 12: it.skip(...) → it(...)  // "should export enhanced node renderer..."
Line 19: it.skip(...) → it(...)  // "should implement LOD (Level of Detail) rendering..."
```

**Status:** ✅ COMPLETE
- Both tests now active
- LOD rendering verification included
- Enhanced rendering tests validate advanced Sigma.js features

**Total Unit Tests Un-skipped:** 4

### Deliverable 2: Playwright Visual Regression Spec

   - Desktop viewport (1280x720)
   - Tablet viewport (768x1024)
   - Mobile viewport (375x667)

2. **Core Graph Rendering** (3 tests)
   - Node rendering with pixel validation
   - Edge rendering with path validation
   - Dynamic edge updates

3. **Level of Detail (LOD) Switching** (3 tests)
   - Far zoom level (zoom < 1)
   - Medium zoom level (1 ≤ zoom ≤ 3)
   - Close zoom level (zoom > 3)

4. **Graph Controls** (2 tests)
   - Zoom buttons and pan controls
   - Minimap functionality

5. **Performance & Accessibility** (2 tests)
   - Multi-node rendering performance (20, 50, 100 nodes)

## GAP 5.2: OAUTH NATS EVENT INTEGRATION

### Deliverable 1: Event Publisher Implementation

**File:** `backend/internal/auth/event_publisher.go` (NEW, 320+ lines)

**Event Publishing Methods (9 total):**

1. **PublishOAuthLoginStarted(ctx, provider, stateToken)**
   - Emitted when OAuth login flow begins
   - Publishes state token (masked for security)

2. **PublishOAuthCallbackReceived(ctx, provider, authCode)**
   - Emitted when auth code received from provider
   - Publishes masked auth code

3. **PublishOAuthTokenExchanged(ctx, provider, userID)**
   - Emitted on successful token exchange
   - Links provider to user for audit trail

4. **PublishOAuthUserCreated(ctx, userID, provider, email)**
   - Emitted on first-time user creation
   - Captures user creation context

5. **PublishOAuthSessionCreated(ctx, userID, sessionID)**
   - Emitted on session establishment
   - Captures session ID for tracking

6. **PublishOAuthTokenRefreshed(ctx, userID)**
   - Emitted on token refresh
   - Minimal data (user only)

7. **PublishOAuthTokenExpired(ctx, userID)**
   - Emitted on token expiration
   - Audit event for security monitoring

8. **PublishOAuthError(ctx, userID, provider, reason)**
   - Emitted on OAuth errors
   - Captures error reason for debugging

9. **PublishOAuthLogout(ctx, userID)**
   - Emitted on user logout
   - Simple session termination event

**Security Features:**
- Token masking: First 4 + last 4 characters only (e.g., "token_ghij")
- Email masking: Domain only (e.g., "user@*****.com" → "@example.com")
- Nil-safe: All methods return nil gracefully if eventBus is nil (optional infrastructure)
- No actual credentials logged

**Struct Definition:**
```go
type OAuthEvent struct {
    ID        string
    EventType string
    EntityID  string
    Data      map[string]interface{}
    Metadata  map[string]string
    CreatedAt time.Time
}
```

**Status:** ✅ COMPLETE

### Deliverable 2: Unit Test Suite

**File:** `backend/internal/auth/event_publisher_test.go` (NEW, 150 lines)

**Tests (14 total):**

1. **PublishOAuthLoginStarted** - ✅ PASS
2. **PublishOAuthCallbackReceived** - ✅ PASS
3. **PublishOAuthTokenExchanged** - ✅ PASS
4. **PublishOAuthUserCreated** - ✅ PASS
5. **PublishOAuthSessionCreated** - ✅ PASS
6. **PublishOAuthTokenRefreshed** - ✅ PASS
7. **PublishOAuthTokenExpired** - ✅ PASS
8. **PublishOAuthError** - ✅ PASS
9. **PublishOAuthLogout** - ✅ PASS
10. **MaskToken** (5 edge cases)
    - Empty token
    - Short token (< 8 chars)
    - Normal token
    - Long token
    - Edge case validation
11. **MaskEmail** (3 test cases)
12. **EventStructure** - Validates JSON marshaling
13. **GracefulErrorHandling** - Nil eventBus handling
14. **NewEventPublisher** - Constructor validation

**Test Results:** 14/14 PASSING ✅

**Verification Command:**
```bash
cd backend && go test ./internal/auth -v
# Output: PASS
```

### Deliverable 3: NATS JetStream Consumer

**File:** `backend/internal/nats/nats.go` (MODIFIED)

**New Methods:**

1. **ensureOAuthConsumer()** (~20 lines)
   ```go
   ConsumerConfig {
       Durable: "oauth-audit",
       Description: "OAuth event audit trail",
       AckPolicy: AckExplicitPolicy,
       MaxAckPending: 100,
   }
   ```
   - Creates durable consumer for fault-tolerant event replay
   - Idempotent (gracefully handles existing consumer)
   - Integrated into NewEventBus() initialization

2. **ReplayOAuthEvents(ctx, fromTime)** (~25 lines)
   - Returns channel of messages for audit trail replay
   - Filter subject: "tracertm.entities.*.oauth.*"
   - Non-blocking with proper cleanup
   - 5-second ack timeout, 100 max pending

**Status:** ✅ COMPLETE

### Deliverable 4: OAuth Service Integration

**File:** `backend/internal/cliproxy/oauth_service.go` (MODIFIED)

**Integration Points:**

1. **OAuthService Constructor**
   - Added `eventPublisher *auth.EventPublisher` parameter
   - Wired EventPublisher dependency injection

2. **HandleAuthorizeRequest()**
   - Publishes `oauth_login_started` event on flow initiation
   - Includes state token (masked)

3. **HandleCallbackRequest()**
   - Publishes `oauth_callback_received` on code receipt
   - Publishes `oauth_token_exchanged` on successful exchange
   - Publishes `oauth_session_created` on session establishment
   - Publishes `oauth_error` on failures
   - All publishing is non-blocking (graceful degradation)

**Status:** ✅ COMPLETE
