Editorial interest 77/100 Selection signal · not a rating of the site

Landing page captured for the 2026-09-29 issue.
For
Caseworkers, lawyers, procurement officers, and document validators
Worth noticing
Version 0.3.1 is marked pre-release; the steward is seeking documents from other platforms and countries to calibrate the thresholds.

Field notes

The rubric is versioned, and the page says applying the same version at the same moment should produce the same grade. It invites people to send in documents they believe were graded incorrectly, while cautioning them to share only files they are allowed to disclose. The page says submitted files and personal data are used for calibration, kept within Edström Business AB, and deleted within 12 months at the latest unless the sender agrees to a public test case.
