See the essential structure first

Begin by identifying the source family before comparing authority or interpreting text. This deliberately incomplete preview has 5 nodes; exceptions and legal consequences remain in the sourced prose below.

Why source hierarchy comes first

US law is distributed across constitutions, enacted statutes, agency materials, judicial decisions, and procedure rules. A reader first identifies source type, jurisdiction, date, and status because those fields determine what comparison is even possible. Guidance is recorded as a source, not silently promoted to binding law.

A constitutional source anchor

The Constitution assigns granted legislative power to Congress. The quote supplies real text for the top source row without deciding any dispute. Verbatim snapshot text: “All legislative Powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and House of Representatives.” Source: U.S. Const. art. I, § 1; https://www.neochart.com/catalog/constitution/articles/article_1/section_1/const_art1_sec1_1a59fd90b5f3/article_i_section_1_0001/index.html; data via neochart.com, snapshot 2026-08.

A source packet for an engineering team

A safe source packet stores the document type, issuing institution, jurisdiction, date, citation, exact text, and source URL. It does not attach an outcome, authority-weight score, or legal recommendation.

Read the hierarchy diagram

The diagram contains 7 source nodes. The branches are a vocabulary map: actual priority questions depend on jurisdiction, subject, date, and conflict rules, so the model stops before declaring which row controls.

Narrow summary

What counts as law begins as a provenance problem: identify the source and its coordinates, quote it accurately, then hand interpretation to the appropriate legal analysis.
