Score any site
All four engines on one URL: the 45-check contract score, drift, AI readiness and guardrails, with one combined score and every finding a click away.
Does the page keep the v0.4.6 contract: tokens, type, motion, color, access, identity?
Do its tokens resolve, and do its values still cluster on a scale?
What can an agent read about the system before it builds?
Can its tokens become a build contract an agent follows?
Run a URL and all four engines light at once. Point at any cell to read the check behind it.

Method
Fire four engines
In parallel, each fetching the page itself: contract score, drift, readiness, guardrails.
Weigh three
The combined score is the contract score at 50%, drift at 30% and readiness at 20%.
Keep one apart
Guardrails grades the bundle it writes for agents, so it reports beside the combined score.
Remember the last run
Your previous combined score for the site is kept in this browser, and the change shows on the next run.
combined score = contract score × 0.5 + drift × 0.3 + readiness × 0.2A ≥ 90B ≥ 80C ≥ 70D ≥ 60F belowChecks that need a browser run are left out of every score.
