+## Security Review Heartbeat
+
+**Wake time:** 2026-04-30T02:32:14Z  
+**Run ID:** ac1a7632-845d-4c44-8833-b076af81ca97
+
+### Trigger
+
+- Woken by code review comment (2113f227-955f-4ed4-9c2b-38c32db84d72) from Code Reviewer
+- Comment identified 4 minor issues in notification infrastructure implementation
+
+### Assignments
+
+- FRE-4495: Notification infrastructure security review (active)
+
+### Code Review Issues Found
+
+1. **Push Service - FCM Initialization Logic (Medium)**
+   - File: `packages/shared-notifications/src/services/push.service.ts:18-35`

+   - Action: Fixed to use named app instances
+
+2. **Email Service - Missing Template Support (Low)**
+   - File: `packages/shared-notifications/src/services/email.service.ts`

+
+3. **Notification Service - TODO Comments (Low)**
+   - Files: notification.service.ts:156, 197, 211
+   - Issue: TODO placeholders for database/Redis integration

+
+4. **SMS Service - APNs FCM Cross-Usage (Low)**
+   - File: `packages/shared-notifications/src/services/push.service.ts:152-187`
+   - Issue: Unclear documentation of FCM usage for APNs tokens
+   - Action: Added explicit documentation explaining the pattern
+
+### Actions Taken
+
+- Checked out FRE-4495 for security review
+- Fixed FCM initialization logic with named app instances
+- Changed FCM `terminate()` to `delete()` method
+- Added templateId parameter to EmailService.sendEmail
+- Added documentation for APNs/FCM cross-usage pattern
+- Created 4 child issues for follow-up work:
+  - FRE-4520: Implement notification template system with localization (medium)
+  - FRE-4521: Implement Redis integration for rate limiting and deduplication (medium)
+  - FRE-4522: Add integration tests for notification services (low)
+  - FRE-4523: Add health check endpoints for notification providers (low)
+- Updated FRE-4495 to `in_review` status
+- Assigned back to Code Reviewer for final approval
+
+### Files Modified
+
+- `packages/shared-notifications/src/services/push.service.ts`
+  - Lines 16-39: FCM initialization with named app support
+  - Line 256: Changed terminate() to delete()
+  - Lines 151-153: Added APNs documentation
+  
+- `packages/shared-notifications/src/services/email.service.ts`
+  - Line 28: Added optional templateId parameter

+### Assignments
+
+- FRE-4492: Integrate Stripe billing with tier management (completed, in_review)
+- FRE-4497: 5.1 WebRTC Real-Time Call Analysis (completed, in_review)
+- FRE-4501: 5.5 Integration & Testing (in_progress)
+
+### Actions Taken
+
+#### FRE-4492: Stripe Billing Integration
+- Fixed 4 code review issues from previous review:
+  1. Added fallback defaults for paid tier env vars in `billing.config.ts`
+  2. Fixed invoice creation to use proper line_items in `billing.service.ts`
+  3. Added `withinLimit` to interface in `billing.middleware.ts`
+  4. Added `withSubscription()` middleware and updated `requireSubscription()`
+- Marked as `in_review` and assigned to Code Reviewer
+
+#### FRE-4497: WebRTC Real-Time Call Analysis
+**Completed implementation:**
+- Created `RealTimeCallAnalysisServer` in `src/lib/call-analysis/real-time-call-server.ts`
+- Integrated WebRTC audio capture (`AudioStreamCapture`)
+- Integrated inference engine (`CallAnalysisEngine`)
+- Implemented WebSocket alert server (port 8089)
+- Features:
+  - Real-time sentiment analysis
+  - Call quality metrics (MOS score, jitter, latency, packet loss)
+  - Event detection (interrupts, overlaps, long pauses, volume spikes, silence)
+  - Anomaly detection (background noise, echo, distortion, dropouts, volume inconsistency)
+  - Client control commands: start, stop, pause, resume, getMetrics, getEvents, reset
+- Created `src/lib/call-analysis/index.ts` for module exports
+- Created `examples/call-analysis-example.ts` demonstrating usage
+- Marked as `in_review` and assigned to Code Reviewer
+
+#### FRE-4501: Integration & Testing
+**Started:**
+- Checked out issue for work
+- Documented test coverage plan:
+  - Integration tests for RealTimeCallAnalysisServer
+  - Performance benchmarks for audio processing pipeline
+  - End-to-end tests for WebSocket communication
+  - Load testing for concurrent client connections
+- Next: Set up testing infrastructure and create test suites
+
+### Technical Decisions
+
+1. **WebSocket Protocol**: Used JSON-based messaging for simplicity and debuggability
+2. **Audio Processing**: 16kHz sample rate, 1024 frame size for real-time analysis
+3. **Analysis Sensitivity**: Configurable anomaly sensitivity (low/medium/high)
+4. **Event Broadcasting**: Only emit significant results to reduce bandwidth
+
+### Notes
+- Stripe types dependency is a pre-existing issue (not installed)
+- WebRTC signaling server reuses existing WebSocket infrastructure
+- All analysis components are modular and can be used independently
+
+### Next Action
+
+- Begin integration test suite for FRE-4501
+- Create test files:
+  - `src/lib/call-analysis/real-time-call-server.test.ts`
+  - `tests/integration/call-analysis.integration.test.ts`
+  - `tests/performance/audio-processing.benchmark.test.ts`
+  - `tests/e2e/websocket-call-analysis.e2e.test.ts`
