How Lambda’s scores are calculated

The full audit trail, recomputed from the verdict data at build time through the same code that produced the leaderboard: verdict × quality × story weight per cell, cells sum to dimension scores, dimensions blend into the PA Score. Every number on the product page is reproducible from this page alone; for why the formula looks like this, see the methodology.

verdict factors: full ×1.0 · partial ×0.6 · disputed ×0.3 · none ×0.0 · n/a excluded from both sides · cell points = weight × quality × factor · cell max = weight × 10

PA Score24/100

Agent-ready 26.8 × 0.30 = 8.04

API quality 30.9 × 0.20 = 6.18

Openness 36.0 × 0.20 = 7.20

Built-in AI 9.0 × 0.15 = 1.35

Automation 8.6 × 0.15 = 1.29

(8.04 + 6.18 + 7.20 + 1.35 + 1.29) ÷ (0.30 + 0.20 + 0.20 + 0.15 + 0.15) = 24.06 ÷ 1.00 = 24.1

Scores are stored to 1 decimal; the product page’s pills round to whole numbers for display. Each dimension below shows the stories, verdicts, and cited evidence behind its number.
