//Evidence records
Sources
Sumivo treats a source as a structured record that explains what a method relies on and where that material applies.
What a source record contains
Each source record should identify the document or URL, the publishing organization, a version or publication date, and the parts of the calculator method it supports. It should also record important exclusions or limits on that applicability.
- Document title or direct URL
- Publishing organization
- Version, revision or publication date
- Applicable formula, definition, unit or scope
- Known exclusions and limits
What does not qualify
A search-result snippet is a discovery aid, not a source. A competing calculator is also not evidence for a formula or claim. Those materials may point toward a primary document, but they do not replace it.
Current publication state
Sumivo is launching in stages. Published calculators cite their primary sources on the page itself, and new tools are released each day only after they clear source and quality review. Calculators still in review remain noindex and out of the public catalog until they meet the requirements for published status.
