Study graph snapshot contract

• Parent: README.md
• Formal index: ../FORMAL_LEDGER.md

Versioned semantic graph export for qualitative / mixed-methods workflows (schemaVersion: 1.0.0).

Scope

• Structural validation only — TypeScript: @a0n/gnosis/study-graph-snapshot (validateStudyGraphSnapshot).
• Publish policy gate — @a0n/gnosis/study-publish-gate (evaluateStudyPublishGate): confirmatory / mixed require preregistration_ref; confirmatory requires at least one hypothesis node.
• This contract does not certify interpretive truth, participant experience, or IRB approval.

CLI

• pnpm run validate:study-snapshot — valid fixture path (from open-source/gnosis).
• pnpm run evaluate:study-publish-gate — gate on valid confirmatory fixture.
