SCR Protocol v1 — The Open Specification for a Versioned Memory of Scientific Answers

SCR Protocol v1 is the open, discipline-agnostic specification of the Scientific Claim Registry (SCR) — a versioned memory of how scientific answers evolve. It defines the rigid minimal core any implementation must honour to interoperate: the object model (question · claim · evidence), structured identifiers and their lifecycle, the claim contract (PECO context, GRADE, gaps, knowledge state), immutable citable versioning, Knowledge Freshness, the machine-first JSON surface, and the provenance/neutrality discipline (‘registers, not arbitrates’). It specifies an open, suggestion-only contribution model and conformance levels, while leaving the periphery open: which domains exist, which AI compiles, which sources are searched, who funds compute. Lipedema is the pilot domain. Status: Draft, offered for adoption and comment; builds on prior art (nanopublications/Trusty URIs, DOI/DataCite, PROV-O, ClaimReview, GRADE, ORCID).
