Question

Which part of which document describes or supports an entity or concept?

Nodes

Document; Version; Section; Passage; Entity; Concept

Relationship sketch

passage → document version
passage → mentions entity
section → concerns concept

Evidence inputs

Original text, offsets or section locators, content hashes, extraction method, and source rights.

Implementation

Preserve document and section boundaries when indexing. Treat mentions as mentions, not verified assertions; keep a route from each retrieved passage back to the actual source.

Acceptance checks

Every passage resolves to an exact source version
Quoted context can be reconstructed
Mention extraction does not silently assert facts

Do not infer

Entity mention, aboutness, evidence support, and endorsement are different relationships.

Publication boundary

Public passages follow source rights; private corpus records remain private.

Source basis

S12, S14, S25. 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.
