# Agent-readiness technologies

One page per technology: what it is, why an agent cares, how far the world has actually adopted it, every check we
run against it, and the documents it is anchored to. Generated from `src/tech/`, so a page cannot describe a check
the container does not perform.

**Not adopting an emerging technology is not a failure.** Every check is gated on detecting the technology first, so
a site that has never published one of these is not assessed on it and appears in no report. What we surface is a
technology that is present and wrong. **Scored** means we check it; **watched** means we follow it and its page
says why we do not.
