Scored by v3 · source-of-truth hashes: score db860d6ac94e · thresholds e94f8b33e500 — verifiable against the canonical scorer.
The 28-day score is the p75 of nightly runs — the stable number to cite. Deterministic metrics (CRR/SSD/TC) show their latest value (they move only when the site changes); timing (TTFUT) and answer-fidelity (AF) are smoothed by 28-day p75 — the same lab-vs-field split Core Web Vitals uses. Synthetic daily measurement, not real-user field data.
An agent gets the basics but will guess on the gaps. 2/3 applicable facts come from machine-readable structured data.

~ llms.txt present + valid high impact Found at /llms.txt but missing H1/blockquote
Business impact llms.txt is the robots.txt for AI: it tells agents what your site is, what matters, and where to find it. Without it AI guesses — and guessing means inaccurate recommendations and lost visibility.
What we measured We fetch /llms.txt and /.well-known/llms.txt and validate the spec (H1 title + a one-line blockquote summary). We also note /llms-full.txt (your full content as Markdown).
How to fix Create /llms.txt with a short summary + key pages; optionally /llms-full.txt with full content in Markdown.
# Your Site
> One-line description for AI agents.

Transport & Trust (SEC 1.0.0)
HTTPS, HSTS, CSP, sniffing, referrer and CORS posture. Diagnostic only — this does not affect the CAV score. A security header does not make a page more legible to an agent, so scoring it would reward a CDN toggle that changes nothing an agent can recover. We measure it and say so.
Per-header findings (6)
| Header | Evidence |
|---|---|
| ✅ HTTPS | served over HTTPS |
| ✅ HSTS | max-age=63072000 |
| ✅ Content-Security-Policy | policy present, script-src does not allow inline |
| ❌ X-Content-Type-Options | missing nosniff |
| ⚠️ Referrer-Policy | no referrer-policy header (browser default applies) |
| ➖ CORS exposure | no CORS headers on the document (normal for an HTML page) |

Third-party impact
211 third-party requests · 2661 KiB (55.3% of transfer) · 1634 ms main-thread — code an agent must also fetch/run before your content settles. Fewer, lazier third-parties = faster, cheaper agent reads.

Wasted JavaScript (by bundle)
Transfer-accurate — each bundle's transfer size × its unused %, ranked by wasted bytes (the biggest code-splitting wins). Unused JS also inflates Token Cost (TC).
