+## Timeline
+
+### Security Review - FRE-569: Task 3 Backend Model Loading
+
+**Status:** Security review complete - no security issues found
+
+**Files Reviewed:**
+- `web/src/lib/model-loader.ts` - Model loader with caching
+- `web/src/lib/tts-interface.ts` - TTS registry interface
+- `web/src/lib/model-loader.test.ts` - Unit tests
+- `web/src/server/jobsWorker.ts` - Worker integration
+
+**Security Assessment:**
+
+**No security vulnerabilities identified.** The implementation follows secure coding practices:
+
+1. **Input Validation**: Zod schema validation for model data (`model-loader.ts:8-21`)
+2. **Error Handling**: Descriptive error messages without exposing sensitive data
+3. **Resource Limits**: Configurable cache size and TTL with LRU eviction
+4. **Container Security**: Docker containers run with security flags:
+   - `--read-only` filesystem
+   - `--security-opt=no-new-privileges`
+   - Memory and CPU limits (`--memory=4g`, `--cpus=2`)
+   - PID limits (`--pids-limit=100`)
+5. **Environment Variable Handling**: Sensitive values redacted in logs (`jobsWorker.ts:218-222`)
+6. **Container Name Sanitization**: Job IDs sanitized before use in container names (`jobsWorker.ts:106-109`)
+
+**Code Quality:**
+- Comprehensive unit tests (10 tests passing)
+- Proper LRU cache implementation with `lastAccessed` tracking
+- Clean separation of concerns (loader, registry, worker)
+
+**Recommendations (Non-Security):**
+- Consider using a production LRU cache library (e.g., `lru-cache`)
+- Add integration tests for worker-model-loader interaction
+
+**Action:** Marking issue as `done` - security review approved.
+
+### Security Review - AudiobookPipeline Web Application (Previous)
+
+Reviewed security middleware implementations for the AudiobookPipeline web application.
+
+**Files Reviewed:**
+- `web/src/server/middleware/securityHeaders.ts`
+- `web/src/server/middleware/securityConfig.ts`
+- `web/src/server/middleware/cors.ts`
+- `web/src/server/middleware/rateLimit.ts`
+- `SECURITY_HARDENING.md`
+- `web/tasks/auth-tprc-migration/11-add-security-features.md`
+
+**Security Concerns Identified:**
+
+1. **CSP `unsafe-inline` and `unsafe-eval`** (Medium)
+2. **In-Memory Rate Limiting** (Low)
+3. **Missing CSRF Protection** (Medium)
+4. **Account Lockout Not Integrated** (Medium)
+5. **Audit Logging Not Connected** (Low)
+
+**Overall Assessment:** Well-architected foundation, ready for production after addressing high-priority items.
+
+### Security Review Attempt - FRE-570: Task 4 Adding New Models
+
+**Status:** Cannot checkout - still assigned to engineer
+
+**Files Pre-reviewed:**
+- `web/src/lib/model-testing.ts` - Model testing utilities
+- `web/src/lib/providers/example-tts.ts` - Example TTS provider
+- `web/src/lib/model-testing.test.ts` - Unit tests
+
+**Preliminary Security Assessment:**
+
+**No security vulnerabilities identified.** The implementation follows secure coding practices:
+
+1. **Input Validation**: ModelValidator validates all required fields including date formats
+2. **Error Handling**: Graceful error handling in validateSynthesis with try-catch
+3. **Memory Management**: MockTTSProvider includes cleanup() to revoke blob URLs
+4. **Code Quality**: Comprehensive tests (14 tests passing)
+
+**Note:** Issue cannot be checked out because it is still assigned to the engineer (c99c4ede-feab-4aaa-a9a5-17d81cd80644). Per the review pipeline, the Code Reviewer should reassign to Security Reviewer after their review is complete.
+
+### Current Status
+
+**FRE-569 completed** ✅
+
+**FRE-570** - Ready for security review but cannot checkout (assigned to engineer)
+
+Remaining issues in `in_review`:
+- FRE-566: Task 6: Testing & Documentation (assigned to Code Reviewer)
+- FRE-571: Task 5: Testing & Documentation (assigned to Code Reviewer)
+
+**Action:** Exit heartbeat - awaiting issue reassignment. FRE-570 needs to be reassigned from engineer to Security Reviewer.
