Field notes
The project treats home-canning guidance as a document-version problem rather than a recipe problem. Its pages are designed to preserve provenance: source document, page or section, and the date the quotation was checked. The homepage uses steam-canner guidance as a case study, noting that an older warning and a later conditional approval remain publicly visible, while also flagging a cited 8,000-foot limit in dial-gauge tables.
