# v3.1 SKOS Fixture

> Test fixture exercising the full v3.1 predicate set. Not a production skill.

## Domain Context

This fixture exists to verify that the runtime — `generate-manifest.js`, `skill-lint.js`,
`skill-graph-route.js`, and the lint-target resolver — iterates the complete v3.1 predicate
set defined in ADR 0001 (SKOS additions: `related`, `broader`, `narrower`) and ADR 0006
(`boundary` canonical for routing-layer; `disjoint_with` separate orthogonal relation
for formal OWL class-disjointness).

The companion test `scripts/__tests__/test-v3-1-skos-runtime.js` builds a manifest entry
from this file and asserts every predicate above appears in the resulting `relations`
block, with relation-target validation passing for all eight references.

## Coverage

Predicates exercised:

- `related` — symmetric SKOS associative relation (skos:related)
- `broader` — SKOS generalisation (skos:broader); triggers Stage 4b parent recall in router
- `narrower` — SKOS specialisation (skos:narrower)
- `boundary` — routing-layer asymmetric handoff (sg:disjointOwnership)
- `disjoint_with` — formal OWL class-disjointness (owl:disjointWith)
- `verify_with` — PROV-O informational influence (prov:wasInformedBy)
- `depends_on` — DCMI requirement (dcterms:requires)

`adjacent` is intentionally NOT exercised here — that's covered by the back-compat
fixture (a separate test asserting the deprecated alias still validates).

## Workflow

This skill has no workflow — it is a fixture, not a procedure.

## Verification

`scripts/__tests__/test-v3-1-skos-runtime.js` exits 0 only when this fixture round-trips
cleanly through the manifest generator and lint relation-target check.
