How Svelte’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 Score34/100

Agent-ready 20.0 × 0.30 = 6.00

API quality 0.0 × 0.20 = 0.00

Openness 90.0 × 0.20 = 18.00

Built-in AI n/a — excluded, its ×0.15 weight renormalized away

Automation n/a — excluded, its ×0.15 weight renormalized away

(6.00 + 0.00 + 18.00) ÷ (0.30 + 0.20 + 0.20) = 24.00 ÷ 0.70 = 34.3 — weights renormalized over the scored components

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.
