Provider Directory
External services that can help discover sources. A provider is not a Source Record: a provider listing, an adapter, or a search hit establishes no source status, identity, support, standing, admission, or corpus closure.
Adapter state, operational-verification state, and corpus-closure state are shown separately, exactly as the pinned inventory records them; none stands in for another.
Pinned inventory snapshot
Typed counts, separate meanings
These count rows in an inventory of candidate providers. They are not a coverage measure, a quality score, or a corpus-closure measure: adding a provider or an adapter does not widen what Counterpedia has admitted.

This directory is a pinned snapshot of a producer-owned artifact, regenerated deterministically from the exact bytes whose digest is shown above. It does not query the providers or the producer at read time, so it can lag the producer. The producer states its own scope: “Descriptive registry of candidate external source services. Inventory/adapter state has no source, support, standing, identity, admission, or corpus-closure effect.” Implementation coordinates that the pinned record keeps for adapters (repository, file, and change references) are held in Counterpedia’s internal provenance record and are not shown on this public page.
Adapter landed
4 rowsAn adapter for this provider is merged into the integration codebase, as of the pinned snapshot. Implemented code only: it is not a statement about what Counterpedia has admitted, or about what public Search reaches.
