SOURCE UNIVERSE // CAPABILITY TRUTH
R/IV Source Registry
The operational matrix for implemented, verified, degraded, blocked, not-configured, and lead-only R/IV source adapters.
Operational adapter matrix
| ADAPTER | SOURCE CLASS | RELEASE-CANDIDATE STATUS | KNOWN LIMITATION | FALLBACK |
|---|---|---|---|---|
| NARA | OFFICIAL ARCHIVE | BLOCKED | Provider-compliant persistence design required | Manual National Archives Catalog search |
| CIA READING ROOM | OFFICIAL DECLASSIFIED ARCHIVE | IMPLEMENTED_NOT_VERIFIED | HTML search and official-original retrieval require deployed exercise | Direct Reading Room search |
| FBI VAULT | OFFICIAL FOIA ARCHIVE | IMPLEMENTED_NOT_VERIFIED | HTML search and official-original retrieval require deployed exercise | Direct Vault search |
| GOVINFO | OFFICIAL GOVERNMENT REPOSITORY | NOT_CONFIGURED | Production API key required | GovInfo public search |
| COURTLISTENER | LEGAL RECORD INDEX | NOT_CONFIGURED | Authenticated API token required | CourtListener public search |
| FEDERAL REGISTER | OFFICIAL REGISTER | IMPLEMENTED_NOT_VERIFIED | JSON adapter implemented; release candidate not deployed | Federal Register public search |
| SEC EDGAR | OFFICIAL REGULATORY REPOSITORY | IMPLEMENTED_NOT_VERIFIED | Fair-access limits apply | EDGAR public search |
| LIBRARY OF CONGRESS | OFFICIAL LIBRARY COLLECTION | IMPLEMENTED_NOT_VERIFIED | Bounded public API search | LOC public search |
| FRUS | OFFICIAL DOCUMENTARY HISTORY | IMPLEMENTED_NOT_VERIFIED | Bounded catalog search | Office of the Historian search |
| INTERNET ARCHIVE | PUBLIC WEB/MEDIA ARCHIVE | IMPLEMENTED_NOT_VERIFIED | Reference-only unless rights and provenance support preservation | Archive.org search |
| GDELT NEWS | GLOBAL MEDIA INDEX | LEAD_ONLY | Discovery and chronology leads are not proof | Direct source verification |
| BLUESKY PUBLIC | PUBLIC SOCIAL LEAD | LEAD_ONLY | Public metadata only; no private content | Public Bluesky search |
| 4CHAN PUBLIC | ANONYMOUS SOCIAL LEAD | LEAD_ONLY | Live public catalog only; no historical completeness | Manual public-board review |
Runtime fields
The live runtime endpoint records adapter status, last test, last success, canary state, latency when measured, acquisition mode, preservation policy, known limitation, fallback route, and deployment version. This public release-candidate matrix does not promote an adapter to VERIFIED before a deployed test succeeds.
Admission boundaries
Official repositories return candidates for review. News indexes, public social posts, and anonymous-board matches are discovery leads only. Leads do not authenticate claims, identify speakers, or establish truth.
Planned registry expansion
Relevant future adapters include Congress.gov, GAO, inspectors general, presidential libraries, NSA releases, DTIC, DOE, OSTI, FEC, USAspending, SAM.gov, patent repositories, Crossref, PubMed, state archives, and university special collections. They are not represented as connected until implemented and verified.
