Question

What supports a particular assertion, and where did that support originate?

Nodes

Claim; Evidence; Source version; Extraction activity; Reviewer

Relationship sketch

claim → supported/contradicted by evidence
evidence → source version
derived artifact → source activity

Evidence inputs

Exact assertion scope, original source locator, observation date, evidence class, and review decision.

Implementation

Make claims first-class records. Preserve source chains and ownership/independence labels. A summary derived from a source is not a new independent source.

Acceptance checks

Every published material assertion has a source or labeled basis
Conflicting evidence remains attached
Unsupported assertions cannot pass the publication-readiness check

Do not infer

Five copies of the same claim do not constitute five independent confirmations.

Publication boundary

Publish safe citations, not secrets, client messages, or restricted originals.

Source basis

S14, S16. See Research/sources.json. Sources support the primitives or named technology. The organization, labels, actions, and acceptance contracts in this catalog are this library's design, not claimed provider requirements.
