# V3 1 Skos Fixture

> Test fixture exercising SKOS predicates (related, broader, narrower), routing-layer suppresses, the ADR 0006 split between routing exclusion and disjoint_with (OWL class-disjointness), and the io_contract composition hook. Used by scripts/__tests__/test-v3-1-skos-runtime.js to verify that the manifest generator, lint, and router all recognize the full canonical predicate set. Not a production skill.

# 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 canonical
predicate set defined in ADR 0001 (SKOS additions: `related`, `broader`, `narrower`),
ADR 0018 (`suppresses` for routing-layer exclusion), ADR 0006 (`disjoint_with` as
the separate orthogonal relation for formal OWL class-disjointness), and the
composition hook `io_contract`.

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)
- `suppresses` — routing-layer asymmetric exclusion (sg:disjointOwnership)
- `disjoint_with` — formal OWL class-disjointness (owl:disjointWith)
- `verify_with` — PROV-O informational influence (prov:wasInformedBy)
- `depends_on` — DCMI requirement (dcterms:requires)
- `io_contract` — machine-checkable artifact inputs/outputs for composition

Retired aliases are intentionally NOT exercised in this fixture; the companion unit
test checks in-memory alias normalization separately.

## 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.
