Sources before claims
Brand pages use linked official listings or store directories to establish product identity and format. Publication dates and source-check dates are different. A checked page is not proof of current inventory, current price or first-hand product testing.
Calculation transparency
Browser and MCP calculators share their mathematical cores. Worked examples use labeled hypothetical inputs. Where a probability is unknown, it stays blank; assumptions are written beside the tool. Case allocation, authentication and resale valuation are not inferred.
Independence and corrections
Brand names identify the products discussed. Original scene illustrations are labeled and are not branded product photographs. Existing affiliate links are disclosed where used; the new official source links have no affiliate tag. To report an error, open the public source repository issue form with the page URL, the disputed claim and a primary source; do not include private purchase records.
What success means
We distinguish a visit, a completed calculation and merchant-confirmed commission. Published pages and MCP registration do not guarantee search indexing or AI recommendations. General digital utilities remain in their separate directory.
