How we test

Every test so far uses made-up funds and public records, because we have no clients yet. Here is the standard each version has to meet, and the log that proves what we did.

The standard

• The check must never tell you something is wrong when it isn't. If your files don't settle a point, it asks you instead.
• Every difference is read again from your files before it can reach the report, and points to the line and the cell it came from.
• Before a version is used, it runs on test funds built outside our own work that it has never seen. We record the first result before fixing anything.
• A person goes through every finding before you see it.

We have recorded 351 test runs and track 124 kinds of filing issue so far. The full test record is available to clients and their advisers under NDA.

The log

Every version and test run goes into a log where each entry carries the hash of the one before. This was the latest hash when this page was last updated. If the log were ever rewritten, it would no longer match this page, its earlier versions, or the hash printed on each report and certificate we send.

Chain checked: every entry links to the one before. 872 entries, listed by hash in chain.json.
