"""v0.5 B.5.c — smoke test for the enterprise document fixture.

Validates `tests/fixtures/v0.5_enterprise_documents.json` against the
B.5.b primitives (subtypes / relations / roles / lifecycle states) and
CLAUDE.md rule #1 (no vertical-specific content).

Scope:
- Schema fields exist and are well-typed.
- Every `subtype` is in DOCUMENT_SUBTYPES.
- Every relation `type` is in the document's ALLOWED_RELATIONS.
- Every `role_at_target` is in ENTERPRISE_ROLES.
- Every `lifecycle_state` is in DocumentLifecycleState.
- The lifecycle_state agrees with `state_from_t1_t7(**frontmatter)`.
- Every relation target resolves (intra-corpus integrity).
- All 10 subtypes, all 4 new relations, all 4 roles, and all 7
  lifecycle states are exercised at least once.
- No vertical tokens anywhere in titles, bodies, or doc_ids.

This test loads the fixture but does NOT call `core/retrieval`,
`core/graph`, or `core/reasoning` — it's a pure data contract test.
