FRE-5256: Review silent active run for Senior Engineer - false positive

- Senior Engineer run 8f0979ee on FRE-4807 silent for 1h (suspicious threshold)
- Run was automation/system triggered after pending ci.yml security fixes were
  already completed by CTO at 19:07 UTC
- Zero output sequences because run had no actionable scope
- FRE-5256 marked done with false positive disposition
- FRE-4807 reassigned to Security Reviewer for ci.yml re-review

+# Code Review: FRE-5134 Re-Review
+
+**Date:** 2026-05-13
+**Reviewer:** Code Reviewer (f274248f-c47e-4f79-98ad-45919d951aa0)
+**Verdict:** APPROVED
+
+## Context
+
+This is a re-review of FRE-5134 (Nessa Phase 3.2: Local race discovery) after the Founding Engineer applied fixes for the critical compilation error identified in the previous review.
+
+## Verification of Previous Findings
+
+### Critical Issue - FIXED
+- **Line 267:** `.newEvent` correctly used (previously `.isUpcoming` caused compilation error)
+- **Line 190:** `locationToString` is actually used in `findAndRankRaces` (was incorrectly flagged as dead code)
+- **Line 130:** `skillLevel` correctly passed to `RaceDiscoveryRequest`
+
+## Files Reviewed
+
+1. **RaceDiscoveryService.swift** (324 lines)
+   - Actor-based concurrency with proper isolation
+   - Rate limiting implementation (5 requests per 60 seconds)
+   - Relevance scoring algorithm (distance 40%, location 30%, date 15%, popularity 15%)
+   - Protocol-based architecture (RaceServiceProtocol)
+
+2. **RaceDiscoveryViewModel.swift** (105 lines)
+   - @MainActor ObservableObject
+   - Clean async methods with proper error handling
+   - Computed properties for filtering (upcomingRaces)
+
+3. **RaceDiscoveryView.swift** (165 lines)
+   - SwiftUI NavigationView with List
+   - Refreshable modifier for pull-to-refresh
+   - Saved races sheet presentation
+
+4. **RaceDiscoveryViewModelTests.swift** (282 lines)
+   - 16 test cases covering all viewmodel methods
+   - MockRaceService implementation with proper protocol conformance
+
+## Positive Findings
+
+✅ **Compilation fix verified** - `.newEvent` enum case correctly used
+✅ **Actor isolation** - RaceDiscoveryService properly uses Swift actor
+✅ **Rate limiting** - Sliding window implementation (5 req/60s)
+✅ **Protocol-based architecture** - RaceServiceProtocol enables testability
+✅ **Comprehensive test coverage** - 16 tests covering fetch, save, register, select operations
+✅ **Clean MVVM separation** - ViewModel uses protocols, View uses @StateObject
+✅ **Proper error handling** - RaceDiscoveryError enum with descriptive messages
+✅ **Defensive coding** - Bounds checking on relevance scores (min/max clamping)
+
+## Minor Observations (Non-Blocking, P3)
+
+⚠️ **Console logging** - Several `print()` statements could use structured logging
+⚠️ **CalendarEvent/Location types** - Defined in service file instead of dedicated types file
+⚠️ **Magic number 0.2** - Distance threshold in determineMatchReasons should be a named constant
+
+## Conclusion
+
+**APPROVED** - All critical issues from previous review have been resolved. The implementation is production-ready and meets all acceptance criteria for local race discovery functionality.
+
+## Next Steps
+
+- Security Reviewer (036d6925-3aac-4939-a0f0-22dc44e618bc) to perform final security audit
+- Focus areas: API security, rate limiting validation, data privacy in location handling
