Registry Stack docs

Registry Stack is for building registry-facing services over data an institution already holds. It adds controlled read access, governed evidence responses, and audit records without turning the registry into a shared database.

Registry Stack has two runtime patterns:

• Protected Registry APIs are scoped, read-only HTTP APIs over existing files, extracts, databases, or legacy registry systems. Registry Relay implements this surface.
• Evidence Gateway is the governed evidence path. A runtime service checks request context, source context, supported policy terms, freshness, redaction, and audit provenance before it returns a claim result, credential, redacted response, protected read, or denial. Registry Notary implements claim evaluation and credential issuance; governed Registry Relay routes use the same Policy Decision Point (PDP) pattern for protected reads.

Use these docs to build and operate both patterns. The product pages are pulled from each repository at build time, so they match the code. For audience, problem, and ecosystem context, see registrystack.org.
