Evidence first. Uncertainty stays visible.

• Exactly 50 U.S. states appear in the state collection.
• Washington, D.C., territories, tribal governments, and federal policy are separate future or contextual layers.
• Proposed, failed, vetoed, repealed, and historical instruments do not supply enacted/current-policy facts.
• Federal requirements remain separate from state-enacted authority.
• Editorial strengths and gaps are labeled as analysis rather than legal fact.

1. Enacted statute or official session law
2. Official bill page and enrolled text
3. Regulation or administrative code
4. Authoritative statewide policy or standard
5. Official agency implementation page
6. Official fiscal note, hearing, report, audit, or budget
7. Official press release
8. Official biography or contact page
9. Reputable legal or research analysis
10. Advocacy summary
11. News report
12. Crowd submission

Important claims should use the first six categories whenever possible. Reachability, authority, currency, accessibility, and claim support are separate questions; a working link proves none of them by itself.

Yesyes

The initial research states yes; claim-level source review is still pending.

No — explicitly statedno

The initial research explicitly states no; this is never inferred from missing evidence.

Partialpartial

The initial research describes partial coverage or authority.

Unclearunclear

Available wording cannot be reduced to one conclusion without inference.

Not applicablenot_applicable

The field does not apply to this record.

Not yet verifiednot_yet_verified

Research or expert verification is still required.

Proposed onlyproposed_only

The described provision appears only in proposed, failed, or vetoed legislation.

Federal requirement onlyfederal_requirement_only

Only the separate federal baseline is explicit in the initial research.

Historical or outdatedhistorical_or_outdated

The cited framework is historical, older, or potentially outdated.

“Not found,” silence, an inaccessible source, or an unverified claim never becomes no. A proposal never becomes enacted law, and a WCAG target never becomes proof of conformance or compliance.

1. Preserve the submitted or source wording and provenance.
2. Check source reachability separately from source authority.
3. Link each material claim to supporting source records.
4. Keep conflicting evidence visible and use an uncertainty value.
5. Require legal/expert review for authority, scope, status, and enforcement claims.
6. Record an accepted research change in the versioned changelog.

Corrections cannot publish automatically. The current correction page prepares a local draft only because an approved intake system, retention owner, and production security boundary have not been established.

• State records and claims remain in draft verification status.
• Material legal claims still require human legal or expert review.
• Some sources are broken, restricted, secondary, or general leads.
• The source lists do not prove every claim is current or fully supported.
• Laws, policies, standards, statements, VPATs/ACRs, and test results do not prove practical accessibility.
• Manual assistive-technology and disabled-user testing remains a Phase 5 launch-readiness task.
