Soapie uses a bundled oil catalog rather than live web lookups. That keeps saved recipes tied to a stable set of SAP values and fatty acid profiles.
Why this is part of the product story
For soapmakers, reference data is not a decoration. It is part of the formula itself. If those inputs drift silently, historical recipes become harder to trust.
What the catalog supports
- 172 bundled oils at launch
- visible SAP and profile context
- stable offline behavior
- versioned calculations that can be explained later
