## 💡 Key Achievements

### 1. Zero to Hero Components
9 components went from **0% coverage to >85% coverage** in a single session:
- ChatInterface: 0% → 96.49%
- ErrorBoundary: 0% → 93.33%
- ContextItemList: 0% → 98.14%
- ContextTierChart: 0% → 87.50%
- LintResultsTable: 0% → 100%
- ReviewResultsPanel: 10.52% → 100%
- ReviewScoreChart: 0% → 90%
- timestampUtils: 0% → 100%

### 2. Bug Discovered & Fixed
**timestampUtils.ts:** Found critical bug where `isValidTimestamp()` returned `true` for `NaN` values
- **Root Cause:** Comparisons with NaN always return false
- **Fix:** Added `Number.isFinite()` check
- **Impact:** Prevents timestamp validation errors in production

### 3. Two-Tier Testing Strategy
Implemented comprehensive testing approach:
- **Tier 1 (Unit):** Fast feedback for developers (10s)
- **Tier 2 (E2E):** Production validation (15min)
- **Combined:** Best of both worlds
