The rules

Five rules go in the system prompt. Each is a sentence that was added after a measured failure, and the deployed pipeline holds each by name in a test, so that a rewrite that lost one fails before any answer is read.

The register of an answer is the voice it is written in: who it is written for, how long it runs, what it leaves out. The register here is the third rule, and it is the one with the most history. The deployed pipeline’s source records the answer that tightened it, on 11 October 2026, the day after the register was planned: the author asked how he could get in trouble using his high beams, and got two sentences inside the count, the first of which ran 36 words with both distances joined by “and Maryland law also says”. His note: “way too detailed and verbose. This is for teenagers.” The rule now carries the answer as it should have read:

Dim your high beams within 500 feet of an oncoming car, or 300 feet behind one. Otherwise it’s a $60 ticket, no points, no court.

The rules you type are shorter than the deployed ones, which have grown sentence by sentence through a hundred and ninety measured questions. The shape is the same.
