All 101 tests you signed off pass. They were replayed on both versions, together with 40 extra workflows recorded after the spec was frozen. The resulting data, exports and printed reports were compared. Then three of your staff used it for a week.
Every statement in SPEC.md is tagged. 1,312 facts came from using the app; 128 came from Ghidra on the Paradox reading code, and are limited to the table layouts.
| wording | 11 dialog messages are worded slightly differently. That's allowed at Compatible. Exact would match them, and every pixel of the screens, for €25,000 more. |
| behaviour | When two users edited the same article, the original silently lost one change. The rebuild warns the second user instead. Say if you want the old behaviour back. |
| look | Same layout, field order and keyboard shortcuts, in a modern font and browser controls. |
| not covered | Patents, trademarks and your original licence terms aren't affected by a clean room. |
