v0.5 Superseded Pre-release

Introduces the A to E grading scale with green-to-red colour direction, three-axis scoring logic (task type, model category, usage intensity) and expanded methodology sources.

  • Base grade grid introduced mapping task type and model category to starting grade
  • Usage intensity modifier: light moves one grade down, heavy moves one grade up
