Spreadsheets and kits that add up.
Every Foundry file is checked before we list it, and every outside number inside shows its source and the date we checked it.
Registry: ok
No formula ships unverified
Every calculation is independently re-derived against a hand-worked test case before a product can be listed — never verified by the same formula being tested.
Never platform-locked
Spreadsheets ship in Google Sheets and Excel 2019+. Doc kits ship in Word, Google Docs and PDF. No product depends on one tool to open it.
One record of truth
Every product fact — price, format, status — comes from one registry. A page never holds its own copy, so a price can't drift between where you find it.

Every calculation is re-derived against a hand-worked test case before a product can be listed. Spreadsheets must pass in both the Sheets build and the Excel build. If a case fails, the product does not ship.

The five registry states every product moves through. A product is live only after its checks pass.
Rates with receipts
Any outside figure — a tax rate, a fee, a threshold — carries its source and an as-of date. A product cannot ship with a figure older than 12 months, and each product page shows the figures it uses.
