How we verify spreadsheet installs

Every install command on this site must appear in docs/RESEARCH.md with a source URL and review date. Package ids must resolve in microsoft/winget-pkgs or formulae.brew.sh when we show them. Asset names must match GitHub Releases.

We mark runtime behaviour we could not personally run as UNVERIFIED and avoid describing it. We do not invent winget or brew ids. We do not claim affiliation with Ascensio System SIA.

Corrections: use the contact page. Independence disclosure also appears on advertising disclosure.

Head term remains spreadsheet. Brand names identify upstream software only.
