Twelve checks. Six of them a computer cannot do.

A lesson goes live here when twelve checks pass. Six of them run in about four seconds. The other six take an afternoon and cannot be automated, which is the reason this site will always be small.

The six a computer does

Required blocks present. Reading grade under 13.0, warning above 11.0. No banned words and no voice tics. Every statistic resolves to a source that exists. Every link alive, and a warning when a lesson is past its stale window. Brand rules — two primary buttons on a page, a rounded corner, a video without a transcript, all fail the build.

None of those checks is clever. They are all things that quietly rot over three months if nobody is watching, which is exactly what an automated check is for.

The six that need somebody

• Is the outcome observable, or does it say "understand"?
• Is the title a moment somebody could overhear in a break room, or a topic?
• Are the entry criteria honest, or written so nobody would ever skip?
• Was the time measured with a stopwatch, or estimated?
• Does every step say what you should see afterwards?
• Are the failures real ones, hit while doing it, or imagined ones?

These are the six that erode first. They are also the six a better-funded competitor cannot buy their way past, because each of them requires somebody to have actually done the thing.

Today's build

The quality bar page shows the current build output, including the warnings. Right now that means two warnings and four unticked person-checks on every lesson. Showing the failing ones is worth more than showing the passing ones.
