C3 ANCHOR — ENGLISH
A public knowledge surface for AI that can pause, review, and verify
C3 (C3 Social Design Center) publishes the same authoritative documents to both people and AI systems, so a claim can always be traced back to its evidence.
What this site provides
C3 Anchor is the public documentation surface behind C3's work on verifiable identity, institutional AI governance, and structures that let an operator pause, roll back, and independently verify a decision — rather than relying on a model's own explanation of itself.
Definitions, specifications, and verification surfaces are published with explicit version, status, and evidence links, so both human readers and AI crawlers can read the same primary source.
English pages
English pages are being added progressively. The links below are the currently activated English translations. Each is tied to a reviewed Japanese source revision and hash. Japanese remains the institutional authority; activation does not certify either page, prove truth, issue a Verify ID, or make the English representation co-authoritative. This does not mean the whole site is bilingual.

Verifiability and Verify ID
Many pages on this site carry a Verify ID — a reference identifier bound to a specific published snapshot in an external registry, so a claim can be checked against the exact evidence it was made from. A Verify ID is locale- and artifact-specific: it is never shared between a Japanese page and an English page, and this frontdoor does not carry one, since it has no bound registry snapshot.
Translation status (draft, under review, or current) is tracked separately from Verify ID, and a page in draft or under review is never presented as current.
