Sectors are deterministic matches from official Congress.gov data and cached bill text. They are source-derived signals, not conclusions about intent or economic effect.

Evidence matches count official fields, normalized subjects, cached text snippets, or extracted entities that matched the sector rules.

Impact is a bill-level rollup used for sorting and filtering. It is not an economic impact estimate.

Confidence is the strongest individual match score behind that sector.

Evidence snippets show why a sector matched and can repeat when Congress.gov repeats the same phrase across official fields.

CBO estimates are official source documents with their own assumptions, scope, and publication dates. They can score a bill, a version of a bill, or a broader legislative package.

LawLinter stores the source link from Congress.gov and does not replace the CBO document. Use these cards as pointers for source review, not as independent fiscal advice.

CBO context shows source-attributed Congressional Budget Office cost estimates linked from official Congress.gov bill records. It is research context only; read the official CBO source document for assumptions, scope, and dates.

Amounts shown here are campaign-finance totals for sponsor or cosponsor-linked candidates and their committees in the displayed FEC cycle.

They are not donations to this bill, spending on this bill, or proof that money influenced or caused sponsorship, cosponsorship, votes, or legislative outcomes.

If multiple linked lawmakers have FEC records, this section can show multiple candidate cards and separate sponsor/cosponsor rollups.

Campaign-finance context uses source-attributed FEC/OpenFEC records that are related or relevant to the displayed bill, lawmaker, candidate, committee, or legislative relationship through deterministic links. It is research context only, not proof of influence, causation, endorsement, or that money caused a sponsorship, vote, or legislative outcome.

LDA filings are public lobbying disclosure records. LawLinter links them here only when the filing activity text contains an exact-looking reference to this bill.

A filing can mention many issues, clients, agencies, or bills. A match should be treated as a pointer for review, not as a conclusion about why legislation changed or how any lawmaker acted.

Lobbying context uses source-attributed LDA.gov records that appear related to this bill through bill references in public lobbying activity descriptions. It is research context only, not proof of influence, causation, endorsement, lobbying effectiveness, or legislative intent.
