Gregory — every assumption, with its receipts

Field notes

Gregory is designed around a register that sits beside an existing workbook rather than replacing it. Its example tracks a supplier deposit percentage and lead time with a source quote and confirmation dates, while the stated workflow turns replies, transcripts, PDFs, and notes into proposed cell changes. The site says reviewers approve, edit, or reject each item and that approved changes receive before-and-after snapshots. It also specifies native workbook features, with no macros or add-ins, as the provenance layer.
