ANSWER-NEUTRAL REVIEW TASK / 10 OCTOBER 2026

Independently review
de Vos curve 20.

Check one tungsten curve from TPRC volume 7 against an exactly pinned EKHI archive record. This page includes no result values and no expected row count.

Start result-blind. Before sealing your own handbook transcription, do not open KIWERB's de Vos result section or anyone else's comparison. If you have already seen one, disclose that prior exposure.

SOURCE-FIRST / OFFLINE

Seal the source first, then compare.

Use only your own lawful access to TPRC volume 7, table 234, curve 20; the target is tungsten at 2000 K.
Download the published blank worksheet and transcribe every visible table row into its unchanged five columns: source_row,wavelength_um,emittance,source_page,transcription_note.
Record the SHA-256, UTC time, page locator, row count and ambiguous characters. This seals the source transcription before comparison.
Verify validator SHA-256 e588bcc7a5aab9839cbb0ce86cafca1cd9b764ccd4b72d4fcda55432556a6bba and run py -3 validate-devos-worksheet.py filled.csv on Windows or python3 validate-devos-worksheet.py filled.csv on macOS/Linux. Keep its JSON output; it confirms structure and file hash only.
Only then open the pinned archive member and independently compare order, lengths, numbers and metadata.
Record agreements, discrepancies and uncertainty. Keep the handbook scan and PDF private.

VERIFY YOUR DOWNLOADS

One pack or individual files.

The English offline pack has SHA-256 04e1b0484c863c32b51a828c62ad4f3e17d5525e32661105475859f8365fc8c5. It contains seven files, including this English task and a clean cross-platform README with every allowed disclosure value. The original compact pack remains available separately. On Windows, check it with Get-FileHash -Algorithm SHA256 devos-volunteer-pack-en.zip. On macOS or Linux, use shasum -a 256 devos-volunteer-pack-en.zip or sha256sum devos-volunteer-pack-en.zip.

Copy the blank worksheet under a new name before editing. The validators make no network requests and write no files.

The second validator independently repeats the full worksheet structure check, binds the worksheet hash, requires a real whole-second UTC seal time and leaves curator fields unchanged; it does not submit or accept a return.

RIGHTS BOUNDARY

Do not share scans.

The source links permit only a narrowly bounded individual-fact check here. Do not upload PDFs, scans or protected full text, and do not perform database-wide extraction.

OPTIONAL MANUAL RETURN

Send route and hash first.

A manual email is optional and reveals your sender address. Initially send only the task name, worksheet hash, role and possible prior exposure; request a checked transfer route before attaching files.

Open the monitored mailbox ↗

No automatic send, live intake, acceptance promise or payment promise.

EVIDENCE BOUNDARY

A return is not confirmation.

KIWERB must separately assess identity, prior exposure, method, source evidence and values. This task claims neither independent validation, a confirmed correction nor a scientific discovery.
