Test yourself before you change yourself.

Most teams find out work is wrong from readers, after it ships, and at AI volume that failure mode scales: more output, more confident, more wrong, faster. The Eval discipline is one sentence: before work ships, it must pass a test that exists in writing and is allowed to say no. A person reviewing is not that test; a person can be tired, rushed, or agreeable, and is worst exactly when volume is highest. A written standard holds on a busy Friday. The standard is never finished: when something wrong ships anyway, the incident closes only when a test now exists that would have caught it. Eval has no territory of its own because its territory is the other six disciplines; remove it and they slowly become theatre. Test the floor first (machine-written tells, unsourced numbers, claims without proof), then the bar: could a competitor have shipped this word for word, and does it add anything a buyer could not already find? The standard that guards this site blocked earlier drafts of this very cluster three times in one day, and each block produced a better sentence.
