Recursive by design

What improved

This school is built to get better over time. The site counts, anonymously, which lessons learners open, which quiz questions they miss and what they ask the professors. Each night an AI review reads those counts. When enough answers show that one of the AI-skills lessons is confusing, it can revise that one lesson (at most one a night). For course lessons it only writes a proposal that a person decides on. A change goes live only after automated checks pass: the code compiles, the tests pass, the site builds, and AI-run design and truthfulness reviews pass. Most nights nothing changes, because traffic is still small. We do not run A/B tests; there is too little traffic to measure them. Here is the log.
