Checks you can run

A build that grades itself and publishes the grade is asking you to trust the grader. So these checks do not read a stored result — they run now, in your browser, and fetch the same files this site just served you. If one fails you will see it fail.

Nothing here is sent anywhere. Open your network tab and watch: every request goes to this host and nowhere else, which is itself one of the checks.

A check nobody has watched fail proves nothing, so four of these are deliberately fed bad input and must report fail — they appear below marked poison. If a poison row ever says pass, the check above it is vacuous and the green beside it is worthless.
