Dual-Mode Snyk Integration + +Implemented both CLI and API scanning: + +```go +cliResult, cliErr := s.scanWithCLI(ctx, opts) +apiResult, apiErr := s.scanWithAPI(ctx, sbomData, sbomFormat, opts) + +// Prefer API, fall back to CLI +if apiResult != nil { + result = apiResult +} else if cliResult != nil { + result = cliResult +} +``` + +**Benefits:** +- Resilience (multiple paths to success) +- Better results from API when available +- CLI fallback for air-gapped environments + +### 3. Graceful Scanner Error Handling + +Exit code handling for scanners that signal vulnerabilities via non-zero exit: + +```go +output, err := cmd.CombinedOutput() + +// Scanner may exit non-zero when vulnerabilities found +// Parse output regardless if it exists +if len(output) == 0 { + return nil, NewScanError("scanner", "no output", err) +} + +return s.parseOutput(output, opts) +``` + +### 4.
