The public error ledger
Every class of error we have ever found, and the rule that now prevents it. Published, dated and numbered — including the ones that were embarrassing.
Why a vendor would do this
Because a competitor cannot copy it without publishing their own defects, and because a new supplier has no other way to earn trust honestly. It is the model aviation uses: report the incident, fix the system, tell everyone.
- Each entry: what went wrong, why, and the rule that stops it
- Numbered rules, versioned protocol, public history
- Your own reports enter the ledger too, with credit
- No entry is ever quietly deleted
Example: the foreign-numeral incident
A page-number format we set produced Devanagari digits instead of Persian ones in some copies of Word. It was caught by a reader, not by us. The fix was to ban live fields from facsimile output entirely and use static text — and a character sweep now runs over every file we ship.
Send us your hardest page
The one with the table that never survives, or the formula that always breaks, or the Persian text that always reverses. That is the page we built this for.
