How Phaser’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 Score31/100

Agent-ready 53.0 × 0.30 = 15.90

API quality 15.4 × 0.20 = 3.08

Openness 46.0 × 0.20 = 9.20

Built-in AI 15.6 × 0.15 = 2.34

Automation 6.0 × 0.15 = 0.90

(15.90 + 3.08 + 9.20 + 2.34 + 0.90) ÷ (0.30 + 0.20 + 0.20 + 0.15 + 0.15) = 31.42 ÷ 1.00 = 31.4

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.
