AXIOM / Scoring Methodology

How AXIOM scores a sitev1.0

Every number is traceable to specific scanner output. No PRNG, no hidden defaults, no fabricated industry data — just deterministic scoring backed by AI interpretation where it adds value.

Section 01 / Scoring Principle

Evidence in, score out.

Every dimension score is computed from real, evidence-backed scanner output. Where a dimension cannot be scored due to insufficient data, it is reported as null with a stated reason — never silently filled with a default value.

Section 02 / Role of AI

Where AI helps — and where it doesn't

AI (Anthropic Claude) is used only to narrate evidence-based findings and produce executive summaries on top of deterministic scores. AI does not generate or modify scores.

Section 03 / The Nine Dimensions

Weighted scoring across nine evidence-based dimensions

01

Accessibility

WCAG 2.2 AA compliance, alt text, contrast, keyboard navigation, ARIA semantics.
