Once Found, Look It Up

This chapter builds the last stage before the model writes: three lookups that turn one retrieved subsection into the whole section it belongs to, the court’s figure for breaking it, and the agency’s page on what happens next. No model is involved, because once retrieval has found the section the rest is a lookup, not a search.

On 10 October 2026 the deployed pipeline’s author asked it, for Texas, what happens if I get pulled over and I don’t have my license with me? and read:

You are required by law to display your driver license when an officer asks for it … a first conviction carries a fine of up to $200.

For Maryland, the same question:

Maryland law requires every driver to have their license with them. The laws given here do not state the penalty.

Both are the rule and a fine. Neither is what happens. The answer a learner wanted was two sentences: in Texas, you’ll get a ticket with a fine of up to $200, but if you bring your valid license to court the charge is dropped; in Maryland, the officer looks you up, and if you’re licensed you’ll usually get a $50 ticket you can pay by mail, no points, no court date.

Three facts were missing, and retrieval could not have found any of them. In Texas the way out is § 521.025(d), the subsection after the fine, and retrieval had found neither (c) nor (d), because each subsection competes on its own words and “defense to prosecution” shares none with the question. In Maryland the $50 is in no section of the Transportation Article at all: it is a row of the District Court’s fine schedule, a PDF. And what happens once the ticket is written, the thirty days to respond to it, is answered by neither; it is on the District Court’s own page.

What the three have in common is the key. What happens is spread over three bodies in every state, and all three are organised by the section number the code uses. The code holds the duty, the penalty range and any way out, under one section. The court’s schedule lists its fines by section. The agency’s pages are not keyed by section, but the family of question they answer is named by the rephraser, and that name is a key of its own. A join key is the value two records share that lets one be looked up from the other, and here it is the section.
