What one record is

One row per tool evaluated. Score = activity 30 + popularity 25 + usability 30 + compliance 15 = 100. Verdict: shelf at 70 or above, watch from 40 to 69, dropped below 40. Usability credit is only given when at least two independent signals agree. The private evidence blob behind each score is not published; the scores are.

Records

This is a scored list, not a recommendation engine. The rubric is fixed and published so a reader can disagree with a specific score and say why.
