claim
Portable BEP 2 object with stable identity, provenance and typed graph links. Context, uncertainty and source lineage are preserved rather than flattened into prose.
Move scientific evidence between tools without losing why it should be trusted.
BEP 2.0 adds stricter typed objects, SHA-256 provenance, JSON-LD semantics, typed links, context-of-use, uncertainty, PROV-O alignment, RO-Crate compatibility and explicit migration from BEP 1.0.

Conformance
SDK, CLI validator and migration path.
JavaScript SDK
lib/bep2.js provides envelope construction, validation and BEP 1 → 2 migration.
CLI
node bin/bep-validate.mjs file.json --migrate --json validates or migrates evidence envelopes with process exit codes for CI without changing production dependencies.
PROV-O
Source, generation activity and attribution semantics map to W3C provenance concepts.
RO-Crate
Optional crate entities allow evidence bundles to preserve associated research objects and hashed artifacts.
JSON-LD context
Semantic reference contract.
