# Story 10.2: Upgrade Audit Section - Completion Checklist

## Story Information
- **Story**: 10.2 - Upgrade Audit Section
- **Epic**: 10 - Audit & Health Checks
- **Priority**: High
- **Effort**: Medium
- **Status**: ✅ COMPLETE

## Acceptance Criteria

- ✅ Identifies deprecated packages from registry metadata
- ✅ Groups upgrades by package name
- ✅ Counts upgrades by type correctly
- ✅ Extracts alternative package suggestions from deprecation messages

### 2. Issues have correct severity
- ✅ Deprecated packages generate Critical issues
- ✅ Major upgrades generate Warning issues
- ✅ Minor upgrades generate Info issues
- ✅ Patch upgrades generate Info issues
- ✅ Severity ordering works correctly (Info < Warning < Critical)
- ✅ Issues include actionable suggestions

### 3. Tests pass 100%
- ✅ 24 new tests added for upgrade audit functionality
- ✅ All 50 audit module tests passing
- ✅ Tests cover all public APIs
- ✅ Tests cover error conditions
- ✅ Tests cover edge cases (no dependencies, disabled sections)
- ✅ Integration tests with AuditManager
- ✅ Serialization tests for all types

### 4. All code verified and updated
- ✅ Removed TODO comment from AuditManager indicating story 10.2
- ✅ No pending TODOs for this implementation
- ✅ All methods fully implemented (no placeholders)

## Implementation Tasks

### Task 1: Create `src/audit/sections/upgrades.rs`

- ✅ Module-level documentation complete

### Task 2: Add issue detection
- ✅ `AuditIssue` struct created in `src/audit/issue.rs`
- ✅ `IssueSeverity` enum created with proper ordering
- ✅ `IssueCategory` enum created

- ✅ Major upgrades → Warning severity
- ✅ Minor/Patch upgrades → Info severity
- ✅ Issues include affected packages
- ✅ Issues include suggestions
- ✅ Issues include metadata for programmatic access

### Task 3: Write tests
- ✅ Test with no dependencies
- ✅ Test with section disabled
- ✅ Test issue creation and mutations
- ✅ Test severity ordering
- ✅ Test category display
- ✅ Test section accessors
- ✅ Test deprecated package structure
- ✅ Test alternative extraction patterns

- ✅ Integration tests with AuditManager
- ✅ All tests passing
- ✅ Tests organized in `src/audit/tests.rs`

### Task 4: Integration with AuditManager
- ✅ Added `audit_upgrades()` method to AuditManager
- ✅ Method properly delegates to section implementation
- ✅ Uses manager's upgrade_manager and config
- ✅ Returns AuditResult<UpgradeAuditSection>
- ✅ Full documentation with examples

- ✅ Uses `config.audit.upgrades` settings
- ✅ Integrated with `PackageToolsConfig`

### With Error System
- ✅ Uses `AuditError::SectionDisabled`
- ✅ Uses `AuditError::UpgradeDetectionFailed`
- ✅ Returns `AuditResult<T>` consistently
