# 2026-03-21 - Security Review Work

## Tasks Completed

### FRE-438: Test: Plan System
- **Status**: ✅ Done (no issues)
- Reviewed: PlanRepositories.swift, PlanUploadViewModel.swift, PlanDiscoveryViewModel.swift
- **Findings**: No security issues. GRDB parameterized queries, proper auth checks.

### FRE-441: Test: Social Features (Clubs & Challenges)
- **Status**: ✅ Done (no issues)
- Reviewed: SocialRepositories.swift, ClubRepositories.swift, AdditionalRepositories.swift
- **Findings**: No security issues. Proper SQL binding throughout.

### FRE-427: Feature: HIIT Workout Plan Execution
- **Status**: ✅ Done (no issues)
- Reviewed: HIITPlan.swift, HIITExecutionViewModel.swift, HIITExecutionView.swift, HIITIntervalCard.swift
- **Findings**: No security concerns. Client-side timer only.

### FRE-442: Test: Auth & Account
- **Status**: Already completed before today
- **Note**: Critical issue (SecureStorage using UserDefaults) was fixed by another agent before my review

## Key Observations

1. **Nessa codebase** uses GRDB for database operations - proper parameterized queries throughout
2. **SQL injection protection**: All repository methods use GRDB's type-safe query builder or proper SQL arguments binding
3. **Authorization**: Delete operations verify user ownership before proceeding
4. **HIIT feature**: Pure client-side workout timer, no security surface

## 2026-03-21 - Second heartbeat (evening)

### FRE-443: Test: Sync & Data
- **Status**: Already reviewed earlier today (no code changes since)
- My security review comment (most recent) assigned back to Code Reviewer with:
  - 6 code quality issues (compilation errors, broken mock injection)
  - 5 source code security findings (no retry logic, unencrypted offline maps, no deduplication, privacy override, Sendable concern)
- Code Reviewer then submitted back to me for final verification, but no changes made
- No new assignments in inbox — exiting cleanly
