```
### Integration
```
Total tests: 254 passed; 0 failed
```
### Clippy
```
cargo clippy -p sublime_pkg_tools --lib -- -D warnings
Finished (no warnings or errors)
```
### Example

2. **Test suite in src/version/tests.rs** (515 lines added)
- 33 comprehensive tests
- All edge cases covered
- Error cases tested
3. **examples/snapshot_version.rs** (126 lines)
- Multiple usage examples
- CI/CD workflow demonstration
- Different format patterns
4. **STORY_5.6_SUMMARY.md** (308 lines)
- Complete implementation summary
- API usage examples
- Design decisions documented
5. **STORY_5.6_CHECKLIST.md** (this file)
- Verification checklist
- Quality assurance
## Files Modified ✅
1. **src/version/mod.rs**
- Added `pub mod snapshot`
- Added exports: `SnapshotContext`, `SnapshotGenerator`, `SnapshotVariable`
- Updated example documentation
- Removed TODO for Story 5.6
## API Verification ✅
### Public API
```rust
// Exported from sublime_pkg_tools::version::snapshot
pub struct SnapshotGenerator { ... }
pub struct SnapshotContext { ... }
pub enum SnapshotVariable { ... }
// All methods documented and tested
```
### Configuration Integration
```rust
// Works with existing PackageToolsConfig
config.version.snapshot_format // Already defined
```
## Feature Verification ✅
### Supported Variables
- [x] `{version}` - Base version number
- [x] `{branch}` - Sanitized git branch name
- [x] `{commit}` - Short git commit hash (7 chars)
- [x] `{timestamp}` - Unix timestamp in seconds
### Branch Sanitization
- [x] Forward slashes → hyphens
- [x] Non-alphanumeric removed (except `-`, `.`, `_`)
- [x] Multiple hyphens collapsed
- [x] Leading/trailing hyphens removed
- [x] Lowercase conversion
### Format Validation
- [x] Empty format rejected
- [x] Missing {version} rejected
- [x] Unsupported variables rejected
- [x] Clear error messages
### Snapshot Generation
- [x] All variables replaced
- [x] Branch names sanitized
- [x] Commit hashes shortened
- [x] Timestamps formatted correctly
## Integration Points ✅
- [x] Works with `Version` type from types module
- [x] Uses `VersionError` for error handling
- [x] Integrates with `PackageToolsConfig`
- [x] Follows version module patterns
- [x] Compatible with existing version resolution
## Performance Considerations ✅
- [x] Regex patterns cached using `OnceLock`
- [x] Minimal allocations
- [x] Efficient string operations
- [x] No unnecessary cloning
## Security Considerations ✅
- [x] Branch name sanitization prevents injection
- [x] Format validation prevents malformed versions
- [x] No unsafe code
- [x] All inputs validated
## Maintenance Considerations ✅
- [x] Clear documentation for future maintainers
- [x] Comprehensive tests prevent regressions
- [x] Well-structured code easy to modify
- [x] Error messages guide users
