OptionalExpected hash compare
Use this when a manifest, CI log, or incident report gives you an expected checksum and you need to confirm whether the current file matches it.
Example workflow
Keep the evidence copy-ready.
- Input: `png_500x300_sample_file_13KB.png` and expected SHA256 from the manifest.
- Match case: status confirms the computed value equals the expected hash.
- Mismatch case: status shows drift so you can route the incident into triage.
