# `src/shared/` — vocabulary, types, pure helpers

Future home: `citation-engine` (the shared types and contracts half of it).
Owns: `Document`, `Selector`, `Annotation`, `EvidenceItem`, `EvidenceLink`,
`EvidenceSet`, state enums, branded IDs, canonical text normalization.

May import from: nothing internal. Leaf node of the dependency graph
(`wiki/DependencyMap.md` §4).
