KIWERB OpenLab - de Vos curve 20 independent review pack (English)

START AND SEAL
1. Read https://kiwerb.de/forschung/devos-independent-review.html before opening any KIWERB result notes.
2. Verify this ZIP SHA-256 against that public page and every extracted file against MANIFEST.json.
3. Copy devos-worksheet.csv to filled.csv and transcribe only your own lawful source reading.
4. Run the worksheet validator locally:
   Windows: py -3 validate-devos-worksheet.py filled.csv
   macOS/Linux: python3 validate-devos-worksheet.py filled.csv
5. Preserve its JSON output and seal the worksheet before opening the pinned archive member.

COMPLETE THE RETURN TEMPLATE
6. Copy devos-return-template.json to completed-return.json. Do not edit schema_version, task_slug, archive_sha256, member_sha256, curator_fields or instructions.
7. Fill source_worksheet_sha256 with the validator output, sealed_at_utc with an ISO-8601 UTC time, source_row_count with the worksheet row count, and source_pages_used with at least one page locator.
8. Choose the exact value that truthfully applies:
   reviewer_role: source_reader | independent_reproducer
   prior_exposure: task_only | saw_result | unsure
   method_origin: independent | kiwerb_reference | unsure
   known_connection: none_known | known_connection | unsure
9. Fill comparison_method, agreements, discrepancies, uncertainty and rights_statement with nonempty text. Use an empty attachment_sha256s list unless you have local attachments; list only lowercase SHA-256 values, never file contents.
10. Run the return validator locally. It independently repeats the full CSV structure check and requires a real whole-second UTC seal time:
   Windows: py -3 validate-devos-return.py filled.csv completed-return.json
   macOS/Linux: python3 validate-devos-return.py filled.csv completed-return.json
11. Keep all files local until a human confirms a transfer route.

TASK.en.json is the exact published English rendering. It binds the unchanged canonical task by SHA-256. Its original volunteer_pack field names the earlier compact package; this wrapper is separately bound by its own MANIFEST.json and the public page.

Do not include or redistribute handbook scans, PDFs or protected full text. The tools perform no network request and do not write files. Structural success is not identity, independence, source truth, scientific validation, acceptance, correction or discovery.

KIWERB permits copying these package files only for personal participation in this named review task. No broader open-source or content license is granted. Third-party sources remain under their own terms.
